Networking doubt

hai friends,
I m new to solaris OS.
i m doing b.tech project in java for connecting windows,linux,solaris10
here i got a problem when im using solaris10
i connected my solaris system to the network by cable. but i dont know where to set the IP address
for the interface. where to find it
without seeing it when i executed my TCP /ip program in java
i got a error during runtime (ie) network unreachable
now i need to know how & where i can identify
n/w card connected and set the IPaddress for it
please help for me urgent.....
i ll be thankful to everyone

1 ifconfig -a (will show you the network interfaces)
2 look at /etc/hostname.(interface from above) for your hostname
3 edit /etc/hosts and change the ip to your new ip for your hostname found in step 2
If ifconfig is only showing lo0 the loop back interface then you have never set up the interface and it is not plumbed.
Probably doing a sys-unconfig would be easyier to do then the following.
But you can do it the long way
dmesg |grep pci
and look to see what the interface name is and do a ifconfig plumb (interface name)
edit /etc/hostname.(interface name) and put in your hostname
edit /etc/hosts and add your ip address
edit /etc/netmasks to add your netmask
edit /etc/defaultrouter to add your router

Doubts regarding WAN Network sizing formula parameters

Hi
We have used the following SAP document - Front end requirements for SAP Business solutions
We have some doubts regarding the formula. Sometime we have the feeling it does not address very well issues as user's concurrency, WAN Optimization and contingency. However, it might be only that we are not using correctly the formula, so we would like to confirm some information regarding the parameters.
C = X * N * D * 0.25
The parameters are as follows:
C: Bandwidth in kbps that is needed for the SAP GUI
X: Amount of data per dialog step in kilo bytes
N: Number of active users (independent of the number of sessions)
D: Average number of dialog steps per minute per user7
Numerical factor: ~0.25 = 8 (kb/kilo bytes ) * 1.25 (protocol overhead) * 1/60 (min/s) * safety factor
1.58 (response time, peak load, different technologies)
The number of active user is the average number of concurrent users (from the total number of users) which are using the network? Therefore, we should calculate first the concurrent users number?
Does any body knows what is the reasoning behind the Numerical Factor and the safety factor? It is a contingency factor? It is related with a network bandwidth contingency?
Has anyone apply WAN Optimization?
Has anyone apply any additional contingency measure additional to the safety factor?
Kind regards
Gonzalo Pérez-Prim

Hi Gonzalo,
As you said, the number of active users is the mean number of concurrent users, since idle users don't normally need bandwidth.
I think that safety factor is an estimated number provided by SAP engineers to increase the final amount, just in case you have different issues that could lead to a lower network transmission rate. As it's a general estimation, please take into account that the particular issues of your network can have some influence in the speed calculation.
Please take into account that maybe you want to switch the option "slow network connection" in SAPGUI, just to decrease the ammount of traffic between frontends and server.
Hope this helps
Best Regards

Try temporarily disabling your firewall and see if you are then able to access the iTunes store.

Configure Network (Ethernet Cards) interfaces doubts.

Hi All,
I m beginner in Solaris/Unix, and I have same problems in configure my network.
I have one machine with 2 Ethernet Cards, this machine has multiboot, than it have Solaris 10 and Windows XP.
I will show the configuration that I have on Window,I need the same configuration in Solaris:
In eth0:
IP: 192.168.0.117 (In Solaris the name of this is in ifconfig is IP, OK?)
Mask: 255.255.255.0 (In Solaris the name of this is in ifconfig is
netmaks , OK?)
Gatway: 192.168.0.254 (In Solaris the name of this is in ifconfig broadcast, OK?)
Primary DNS: 192.168.0.254 (In Solaris I don�t know how configure this)
Secondary DNS: void (In Solaris I don�t know how configure this)
I Have an DHCP Server in 192.168.0.254, than I can use dhcp.
The problems, When I try use DHCP:
Ifconfg eth0 DHCP
This command delay and return an Error.
If Itry configure manually, like
Ifconfg eth0 192.168.0.117 (this OK)
Ifconfg eth0 netmask 255.255.255.0 (this OK)
Ifconfg eth0 broadcast 192.168.0.254 (here the 254 is changed to 255 that is broadcast default, but in my net broad cast or router is in 254)
Other thing how I save this configuration. When I restart I lost all changes�
Well in second interface the problem is same, but I didn�t have DHCP:
IP: 200.44.136.145 (In Solaris the name of this is in ifconfig is IP, OK?)
Mask: 255.255.255.192 (In Solaris the name of this is in ifconfig is netmaks , OK?)
Gatway: 200.44.136.129 (In Solaris the name of this is in ifconfig broadcast, OK?)
Primary DNS: 4.2.2.2 (In Solaris I don�t know how configure this)
Secondary DNS: void (In Solaris I don�t know how configure this)
fconfg eth1 200.44.136.145 (here .44 is changed to 36)
Any one can help-me please?
Thanks

yes. you got it .... eg..
/etc/hostname.le0
/etc/hostname.le1
in here put the hostname ... so at the shell prompt:
# hostname <cr>
should give your hostname.
now, in the hosts file: eg:
# Internet host table
127.0.0.1 localhost
<your ip address> <your hostname> loghost
129.156.89.252 host2
you need to reboot after this.
if you get a 'bad address' error on boot,
you probably have a mismatch of hostnames/ip addresses somewhere in their respective files.
also, see:
# man hosts
# man ifconfig

Hi small doubt on network app?

Hi we have developed an app in java which works on LAN. But according to new requirement we need to run that app on LAN which is established via WIFI. I mean all the systems connect to LAN using WIFI. So is there anything special that we have to do to make the app run on the WIFI LAN?

I am not sure but i think the network protocol(collision detection etc) will be implemented by OS By the TCP/IP networking stack, inside the OS.
and then then the tcp/ip is implemented by sockets. Am i right?Not so much right as meaningless. A socket is an endpoint of a TCP connection, or a UDP endpoint.
as far as i know networking is a concept. if it has to be established there should be a protocol well implemented. One such protocol is WIFI which makes the systems to establish LAN. Please correct me if i am wrong.I don't really np know what all this is supposed to mean or how it affects your project, whatever that is. Perhaps you could ask a specific question?

Request to clarify my doubt - ESXi5.1 -Networking

Dear experts,
This is my post in this forum and I am trying to learn vmware esxi as much as possible. Sorry to ask you very basic questions.
I have created the following environments for learning purpose.I have a physical server (64 GB RAM) where installed esxi 5.1 and created 4 VM machines with 8GB RAM on top of this. Each VMs has 2 Network ethernet cards. I have used the 4 vm as follows.
VM-1 for openfiler (storage)
VM-2 for another esxi host -1
VM-3 for another esxi host -2
VM -4 for vCenter server
Now from vCenter server, I have added the hosts (VM-2, VM-3) in inventory and created another 2 VMs (nested vms) on VM-2 host only and installed CentOS on these VMs. I have also configured a virtual standard switch on VM-2 (esxi host-1 above) so that two CentOS are able to connect each other over the virtual standard switch. But while trying to assign the IP address of CentOs , I am not seeing any hardware Ethernet available in CentOs and 'ifconfig -a ' command show 'veth0' instead 'eth0' . Is it happening because of Nested VM ? Is it my correct configuration ? If I am able to assign IP address in CentOS , can both OS communicate each other over the standard switch?
Thanks in advance.
Regards,
Tarun

Thank you for the reply.
I am able to assign IP address in Nested VMs through veth0 , but both the VMs are not pinging each other over the standard switch. Both VMs are in same server.
Am I missing some configuration ?
Thanks once again.

Tarun

I want a new and more powerful (non-Apple) wireless router but I still want to use my existing Time Capsule to continue with my Time Machine backups and I still need the Time Capsule's Network Attached Storage (NAS) features and capabilities

THE SHORTER STORY
My goal is to successfully use my existing Time Capsule (TC) with a new and more powerful wireless router. I need a new and more powerful wireless router in order to reach a distant Denon a/v receiver that is physically located in a master bedroom some 50 feet away from my modem. I need to provide this Denon a/v receiver with an Internet connection so that it can obtain its firmware updates and I need to connect this Denon a/v receiver to my network in order to use its AirPlay feature. I believe l still need the TC's Network Attached Storage (NAS) features because I am not sure if the new wireless router will provide me with the NAS like features / capabilities I need to share files between my two Apple laptops with OS X 10.8.2. And I know that I absolutely need my TC's seamless integration with Apple's Time Machine (TM) application in order to continue to make effortless backups of my two Apple laptops. To my knowledge nothing works with TM like Apple's TC. I also need the hard disk storage space built into the TC.
I cannot use a long wired Ethernet cable connection in this apartment and I cannot use power-line adapters. I have read that wireless range extenders and repeaters are difficult to successfully set-up and that they will reduce data speeds, especially so when incorrectly set-up. I cannot relocate my modem and/or primary base station wireless router.
In short, I want to use my TC with my new and more powerful wireless router. I need to stop using the TC to connect to the modem. However, I still need the TC for seamless TM backups. I also need to use the TC's built in hard drive for storage. And I may still need the TC's NAS capabilities to share files wirelessly between laptops because I am assuming the new wireless router will not provide NAS capabilities for OS X 10.8.2 (products like this/non-Apple products rarely seem to work with OS X 10.8.2/Macs to provide NAS features and capabilities). Finally, I want to continue to use my Apple laptop and AirPlay to wirelessly access and play my iTunes music collection stored on the TC's hard drive. I also want to continue to use my Apple laptop, AirPlay and Apple TV to wirelessly watch movies and TV shows stored on the additional external hard drive connected to the TC via USB. Can someone please advise on how to set-up my new Asus wireless router with my existing TC in such a way to accomplish all of this?
What is the best configuration or set-up to accomplish my above goals?
Thank you in advance for your assistance!!!
THE FULL STORY
I live in an apartment building where my existing Time Capsule (TC) is located in my living room and serves many purposes. Specially, my TC is at least all of the following:
(1) Wi-Fi router connected to Comcast Internet service via Motorola SB6121 cable modem - currently the TC is the Wi-Fi base station that connects to the modem and has the gateway address to the Internet. The TC now provides the DHCP service for the Wi-Fi network.
(2) Wireless router providing Internet and Wi-Fi network access to several Wi-Fi clients - two Apple laptop computers, an iPod touch, an iPad and an iPhone all connect wirelessly to the Internet via the TC.
(3) Wired Ethernet router providing Internet and Wi-Fi network access to three different devices - a Panasonic TV, LG Blu-Ray player and an Apple TV each use one of the three LAN ports on the back of the TC to gain access to the Internet.
(4) Primary base station in my attempt to extend my wireless network to a distant (located far away) Denon a/v receiver requiring a wired Ethernet connection - In addition to the TC, which is my primary base station, I am also using a second extended Wi-Fi base station (a Netgear branded product) to wirelessly extend my WiFi network to a Denon receiver located in the master bedroom and requiring a wired Ethernet connection. I cannot use a wired Ethernet connection to continuously travel from the living room to the master bedroom. The distance is too great as I cannot effectively hide the Ethernet cable in this apartment.
(5) Time Machine (TM) backup facilitator - I use my TC to wirelessly back-up two Apple laptops using Apple's Time Machine (TM) application. However, I ran out of storage space on my TC and therefore added external storage to it. Specifically, I added an external hard drive to my TC via the USB port on the back of the TC. I now use this added external hard drive connected to the TC via USB as the destination storage drive for my TM back-ups. I have partitioned the added external hard drive, and each of the several partitions all have enough storage space (e.g., each of the two partitions used by TM are sized at three times the hard drive space of each laptop, etc.). Everything works flawlessly.
(6) Network Attached Storage (NAS) - In addition to using the TC's Network Attached Storage (NAS) capabilities to wirelessly back-up two Apple laptops via TM, I also store other additional files on both (A) the hard drive built into the TC and (B) the additional external hard drive connected to the TC via USB (there are additional separate partitions on this drive for these other additional and non-TM backup files).
I use the TC's NAS feature with my Apple laptop and AirPlay to wirelessly access and play my iTunes music collection stored on the TC's hard drive. I also use my Apple laptop, AirPlay and Apple TV to wirelessly watch movies and TV shows stored on the additional external hard drive connected to the TC via USB. Again, everything works wirelessly and flawlessly. (Note: the Apple TV is connected to the network via Ethernet and a LAN port on the back of the TC).
The issue I am having is when I try to listen to music via Apple's AirPlay in the master bedroom. This master bedroom is located at a distance of two rooms away from the TC's current location in the living room, which is a distance of about 50 feet. This apartment has a long rectangular floor plan where each room is connected to the next in a straight line. In order to use AirPlay in the master bedroom I am using a second extended Wi-Fi base station (a Netgear branded product) to wirelessly extend my WiFi network to a Denon receiver located in the master bedroom and requiring a wired Ethernet connection. This additional base station connects wirelessly to the WiFi network provided by my TC and then gives my Denon receiver the wired Ethernet connection it needs to use AirPlay. I have tried moving my iTunes music directly onto my laptop's hard drive, and then I used AirPlay on this same laptop to connect to the Denon receiver. I always get a successful connection and the song plays, but the problem is that the connection inevitably drops.
I live in an apartment building and all of the many wireless routers in this building create a great deal of WiFi interference on both the 2.4 GHz and 5GHz bands. I have tried connecting the Netgear product to each the 2.4 and 5 GHz bands, but neither band can successfully maintain a wireless connection between the TC and the Netgear product. I also attempted to maintain a wireless connection to an iPod touch using the 2.4 GHz band and AirPlay on this iPod touch to play music on the Denon receiver. Again, I was able to establish a connection and successfully play music, but after a few minutes the connection dropped and the music stopped playing. I therefore have concluded that I have a poor wireless connection in the master bedroom. I can establish a connection, but it is intermittent with frequent drops. I have verified this with both laptops by working in the master bedroom for an entire day on both laptops. The Internet connection in this master bedroom proved to drop out frequently - about once an hour with the laptops. The wireless connection and the frequency of its dropout are far worse with the iPod touch and an iPhone.
I cannot relocate the TC. Also, this is an apartment and I therefore cannot extend the range of my network with Ethernet cable (I cannot drill through walls/ceilings, etc.). It is an old building with antiquated wiring and power-line adapters are not likely to function properly, nor can I spare the direct power outlet required with a power-line adapter. I simply need every outlet I can get and cannot afford to block any direct outlet.
My solution is to use a more powerful wireless router. I found the ASUS RT-AC66U Dual-Band Wireless-AC1750 Gigabit Router which will likely provide a better connection to my wireless Internet in the master bedroom than the TC. The 802.11ac band of this Asus wireless router is totally useless to me, but based on what I have read I believe this router will provide a stronger connection at greater distances then my TC. And I will be ready for 802.11ac when it becomes more widely available.
However, I still need to maintain the TC's ability to work seamlessly with TM to backup my two laptops. Also, I doubt the new Asus router will provide OS X 10.8.2 with NAS like features and capabilities. Therefore, I still would like to use the TC's NAS capabilities to share files on my network wirelessly assuming the Asus wireless router fails to provide this feature. I need a new and more powerful wireless router, but I need to maintain the TC's NAS features and seamless integration with TM. Finally, I want to continue to use my Apple laptop and AirPlay to wirelessly access and play my iTunes music collection stored on the TC's hard drive. I also want to continue to use my Apple laptop, AirPlay and Apple TV to wirelessly watch movies and TV shows stored on the additional external hard drive connected to the TC via USB. Can someone advise on how to set-up my existing TC with this new Asus wireless router in such a way to accomplish all of this?

In regards to a Plan B, I hear ya brother. I am already on what feels like Plan Z. Getting WiFi to a far off room in an apartment building crowded with WiFi routers is a major pain.
I am basing my thoughts on the potential of a new and more powerful router reaching the far off master bedroom based on positive reviews on cnet.com, pcmag.com and pcworld.com. All 3 of these web sites have reviewed the Asus RT-AC66U 802.11AC wireless router as well as its virtual twin cousin 802.11n router. What impressed me is that all 3 sites rated this router #1 overall in terms of both range and speed (in both the 802.11n and 802.11AC flavors). They tested the router in real world scenarios where the router needed to compete with a lot of other wireless routers. One of the sites even buried this Asus router in a media room with thick walls and inside a media cabinet. This Asus router should be able to serve my 2.4 GHz band wireless clients (iPod Touch and iPhone 4) with a 2.4GHz Wireless-N band offering some 50 feet of dependable range and a 60 Mbps throughput at that range. I am hoping that works, but it's borderline for my master bedroom. My 5 GHz wireless clients (laptops) will enjoy a 5GHz Wireless-N band offering 150 feet of range and a 200 Mbps throughput at that range. I have no idea what most of that stuff means, but I did also read that Asus could reach 300 feet and I got really excited. My mileage may vary of course and I'm sure I'm making some mistakes in my interpretation of their data. However, my Winter 2009 Time Capsule was rated by cnet.com to deliver real world performance of less than that, and 802.11AC may or may not be useful to me someday. But when this Asus arrives and provides anything other than an excellent and consistent wireless signal without drops in the master bedroom it's going right back!
Your solution sounds great, but I have some questions. I'm using OS X 10.8.2 and Airport Utility (version 6.1 610.31) and on its third tab labeled "Wireless" the top option enables you to set "Network Mode" to either:
Create a wireless network
Extend a wireless network
Off
Given your advice to "Turn off the wireless on the TC," should I set Network Mode to Off? Sorry, I'm clueless in regards to how to turn off the wireless on the TC any other way. Can you provide specific steps on how to turn off the wireless on the TC? If what I wrote is correct then what should the rest of this Wireless tab look like, or perhaps it is irrelevant when wireless is off?
Next, what do you mean by "Configure the TC in Bridge Mode?" Under Airports Utility's fourth tab labeled "Network" the top option "Router Mode" allows for either:
DHCP and Nat
DHCP Only
Off (Bridge Mode)
Is your advice to Configure the TC in Bridge Mode as simple as setting Router Mode to Off (Bridge Mode)? If yes, then what should the rest of this "Network" tab look like? Anything else involved in configuring the TC in Bridge Mode or is it really as simple as setting the Router Mode to "Off (Bridge Mode)"?
How about the other tabs in Airport Utility, can they all stay as is assuming I use the same network name and password for the new Asus wireless router? Or do I need to make any other changes to the TC via Airport Utility?
Finally, in regards to your Plan B suggestion. I agree. But do you have a Plan B for me? I would greatly appreciate any alternative you could provide. Specifically, if you needed a TC's Internet connection to reach a far off corner of your home how would you do it? In the master bedroom I need both a wired Ethernet connection for the Denon a/v receiver and wireless Internet connection for the iPhone and iPod Touch.
Power-Line Adapters - High Cost, Blocks at Least One Wall Outlet and Does Not Solve the Wireless Need
I actually like exactly one power-line adapter, which is the D-Link DHP-540 PowerLine AV 500 4-Port Gigabit Switch. This D-Link power-line adapter plugs into your wall outlet with a normal sized plug (regular standard power cord much like any other electronic device) instead of all of the other recommended power-line adapters that not only use at least one wall outlet but also often block the second outlet. You cannot use a power strip with a power-line adapter which is very impractical for me. And everything about my home is strange and upside down. The wiring here is a disaster and I don't have faith in its ability to carry Internet access from the living room to the master bedroom. And this D-Link power-line adapter costs $90 each and I need at least two to make the connection to the Denon A/V receiver. So, $180 on this solution and I still don't have a dependable drop free wireless connection in the master bedroom. The Denon might get its Ethernet Internet connection from the power-line adapter, but if I want to use an iPhone 4 or iPod Touch to stream AirPlay music to the Denon wirelessly (Pandora/iTunes, etc.) from the master bedroom the wireless connection will not be stable in there and I've already spent $190 on just the two power-line adapters needed.
Extenders / Repeaters / Wirelessly Extending the Wireless Network
I have also read great things about the Amped Wireless High Power Wireless-N 600mW Gigabit Dual Band Range Extender (Repeater) SR20000G and the My Net Wi-Fi Range Extender. The former is very powerful and the latter is easier to install. Both cost about $150 ish so similar to a new Asus router. However, everything I read about Range Extenders points to them not being very effective for a far off corner of your house wherein it's apparently hard to place the range extender in the sweet spot where it both gets a strong enough signal to actually effectively extend the wireless signal and otherwise does not reduce network throughput speeds to unacceptable speeds.
Creating a Roaming Network By Hard Wiring with Ethernet Cable - Wife Would Say, "**** No!"
Even Apple seems to warn against wirelessly extending your network (see: http://support.apple.com/kb/HT4145#) and otherwise strongly recommends a roaming network where Ethernet cable is used to connect two wireless base stations. However, I am in an apartment where stringing together two wireless base stations with Ethernet cable would have an extremely low wife acceptance factor (WAF). I cannot (both contractually and from a skill prospective) hide Ethernet wire in the walls or ceiling. And having visible Ethernet cable running from room-to-room would be unacceptable, especially to the wife.
So what is left? Do you have a Plan B for me? Thanks in advance for your help!

Network security: SSL / TLS connections or not?

Hi,
Our small office-network is administered by a (very good) self-employed debian dev, and in the last six years I have learned a great deal by reading through configfiles on our server. I have even setup my own (modest) homeserver and am very interested in everything about networking.
Earlier this year there were the SSL-vulnerabilities, so I glanced through our own setup and I think I have found a weakness that I'm not sure of if it is serious or not.
Internal authentication is handled with LDAP / Kerberos, so at this level I see no problems, but connections to f.e. our LDAP-server are not protected with SSL or TLS and thus my question: should this not be mandatory on an office network that (although protected by iptables) allows connections with the internet?
Our server handles next to LDAP / Kerberos also apache, postgresql, imap, smtp, calDAV, NFS, cups etc...
THX!

Our LDAP-server is used to authenticate users (LAN only), but also as an addressbook (LAN only, although exposed through a local web app).
But other services are exposed to the internet: imap, smtp, http, etc. Whenever I need to add a new device (smartphone f.e.), I'm confronted with the setting 'encryption', which has to be left blank for our setup. That's why I have my doubts...
But you seem to find encryption something 'optional' if I understand you completely. So my doubts are probably not warranted. THX for your reply!

Unplugging all network devices from Fios router prevents DVR freezing and remote control lock ups.

All,
I recently had a Verizon tech visit my house due to constant DVR and remote control freezing. TV content was freezing whether it was locally recorded, pulled from another DVR in the house, or On Demand. On a hunch after the tech tested everything and was about to leave, he unplugged my gigabit switch from the Fios router. Lo and behold everything started running perfectly. Since to the tech, the problem was solved, he closed the case and was on his way. The probem is of course I have more devices than the built in router switch provides ports for. My network is compised of an 8 port Netgear gigabit switch downstream from the Fios router with two wireless access points (with their own built in gigbait switches) connecting to the Netgear gigabit switch. There are no loops in the switch topology. I've tried changing out the router, the gigabit switch, removing the wireless acces points individually as well as plugging the access points directly into the Fios router switch (one at a time with no Netgear switch in the middle) and all scenarious cause the DVR/remote control freeezing to come back. The only devices I can plug into the Fios router without causing freezes are PC's....anything with it's own switch essentially brings the network to it's knees. If anyone has an idea how to get my network back in one piece AND make the DVR's/remotes behave, I'd greatly appreciate the help!
My Fios equipment:
MI-424WR GEN-3I rev I (eye) running firmware 40.19.36
5 Motorola HD-DVRs all QIP 7232-2 running software release 1.9.1 platform build 25.39 (Oct. 22, 2012)
Specific config:
75/35 Fios connecting via ethernet from ONT. Set-top boxes connect to Fios router coax port via powered splitter.
*All SNR/dB mesasurements taken by the tech from the set-top boxes and router are well within spec.
Fios router provides DHCP addressing. Wireless N access points are configured for roaming with the same SSID and non-overlapping channels. Access points are not providing routing or IP adressing...all layer 3 and up services still provided by Fios router

I am inclined to echo several of the "tns" comments, particularly with respect to your splitter. My layout is based on a standard 8-port splitter of the type usually supplied in a VZ install. In addition I do have a ChannelPlus device that functions as a powered splitter, but its use is limited to distribution of secondary TV signals to older analog TVs. My first point then is that this may be an offender as "tns" has suggested.
In addition, I'd describe your wiring as "non-standard" (red-colored items in the above diagram)  As you're no doubt aware, with 75/35 you don't really need Cat5e from the ONT (your original diagram). It seems the highest tiers do require it, but in "standard" installations this run is coax directly to an 8-port non-powered splitter (below diagram), then from that splitter via coax to all STBs and CableCards, other TVs, et.), and also to the Actiontec.   Subsequent feeds from the Actiontec to wired devices (including WAPs) are via Ethernet (typically Cat 5e).
In fact I don't immediately see how your STBs get additional services such as On Demand and IMG with the wiring shown in your diagram (perhaps someone can help me out here). In "standard" installs the Actiontec must be connected via coax to the ONT to provide such services to other network clients. I don't see that requirement being met here.
For starters I'd recommend that you change your service from WAN Ethernet to WAN coax. This can easily be accomplished over the telephone. Then I'd run coax directly from the ONT to the Actiontec as in my revised diagram below (blue-colored items). If your setup can manage with this arrangement, I think it will help greatly with the "freezing" issue.

Subsequent Note: You provided additional info while I was composing a response, and I'd like to offer another comment. Structured wiring "panels" of the type usually available are pre-configured to provide data, phone and video. This usually means that one is in certain respects limited by the ideas of the panel designer. I have what can be called a structured wiring layout, but it really is composed of individual small custom networks for each service (automation, security, video, data, telco, etc.), configured so that all wiring terminates in "home run" fashion at a central panel (a few details here: http://forums.verizon.com/t5/Home-Networking/Cmon-Show-Us-Your-Network/m-p/481733#M765 ). This layout makes it easier to make adjustments (and there have been quite a few over the intervening years). I'm thinking that in your case you may have to abandon the powered splitter (presumably) built into the panel in order to avoid your present fix.
Subsequent Subsequent Note:   From your description it seems that you are using more than a single "whole house" DVR to supply programming to other devices. This is a bit puzzling to me because somewhere along the line I recall reading that only a single whole house DVR was allowed on the network. Can you elaborate a bit?

What is needed to network 2 computers using Airport card

I know I need an airport card in my eMac, but is there any other cards that have to be in the computer? I want to network my eMac with an iMac using a DSL line. The eMac will be downstairs and the iMac will be upstairs. I'm waiting for delivery from Apple of the iMac. It has everything built in that is needed to network but my eMac doesn't. To make my eMac wireless is all I have to buy is an Airport Card and a Wireless Gateway for the iMac which is the computer connected to the DSL modem and Wireless USB adapter with connects to the eMac? What type of Airport Card do I need to buy for my eMac (model #'s etc.) It is the card that inserts above the super drive in the front of the computer. Is there any software that is needed to install Airport?

I am also doing some configuration changes (we have one Imac and two eMac's)
but one eMac does not have a airport card and is hardwired (ethernet) to the high speed cable modem then a apple airport. One Imac and the Emac with a airport card work fine, it is a bit tricky finding the correct airport card (or airport extreme card if you have a ATI graphics card (use about the mac/system profiler then click on more to see if you have a graphics card (which affects which airport card you need, there are alot of resellers on the net so you should find what you want.
If in doubt there is a free program mactracker which provides data on every mac made (available off off versiontracker.com (free site just register) it will guide
you on the type of card needed. I was quite amazed at the amount of different spec eMac's made in their relativealy short history.
Macwireless.com does sell eMac cards (for two models) but also antenna type
or flash drive appearing USB based wireless connectors that may help.
I found the mactracker program helpful (alot) as alot of web sites provide some vague info and I would hate to se you get stuck with a non returnable card.
The actual card install does not look hard (its done through the cd rom drive door.
I am not sure why we did not get a airport card for ours when we bought it.
Wish I did as it would have saved some $ (maybe) and surf time making sure I find the right one.
We did have a antenna wireless antenna for a "green" Imac (long gone) and it ran on OS9 but it was finicky when we had the airport base station upstairs
and the Imac and antenna in the basement (about 50-75 feet)
Best of luck
Hope this helps, I am not a expert, the serial number on the cd drawer will
nail down the model you have and what you need.
We have been working adding a laser printer and airport express and the two macs with cards work fine but the Emac with no card can not be set up yet. The laser printer will sure save on ink!

Need help to deploy IP Multicast in private network

Hi,
I am currently working on a project where there is an urgent requirement to deliver an IP multicast solution.
The network itself is fairly simple.
IP Cameras as connected to pairs of Catalyst 2960 switches in 'access nodes'. There are 8 cameras per node, 4 on each switch. There are multiple nodes, 3 at the moment in our testing environment, all trunked together, so 24 cameras in total.
The Catalyst 2960 switches are trunking to a Core node, which consists of a pair of Catalyst 3750 switches with MHSRP configured for each of 8 VLANs, with 2 DCs and 2 Video storage servers for storing camera footage attached to access ports on those switches. We also have workstations attached to the core node switches which have software installed to view live images and manage the cameras across the network.
We have no routing - the access switches have default gateways pointing to the VLANs SVIs configured on the core switch, and each function has its on VLAN. InterVLAN routing is enabled on the 3750s and connectivity is working fine.
I wish to send a TCP stream to the Video Storage servers for storage, and to multicast to the workstations so that the software can see multiple streams from multiple cameras.
Could someone please suggest a suitable deployment strategy, including how to configure the cameras and switches appropriately to allow this to happen? I am struggling to understand what type of configuration is required.
Much appreciated. I'm actively viewing this thread for assistance.

I don't think IP Base supports any PIM mode other than PIM stub routing (unless you know otherwise) so your solution wouldn't work. Or perhaps i am not understanding ?
Martin
I think the only way forward is to test what we have already covered.
I didn't realise this was a test environment so at least you can try all things out without worrying about the production network.
The thread i linked to suggested that you can get the routing working even without a L3 device capable of running full multicast routing but at the moment the question concerns those extra commands you can't enter. Can you verify they are not available in config mode ?
An additional problem is because PIM is passive on the SVIs no IGMP queries are being made so there is no way for the switches to work out which ports needs the multicast stream and so it will be flooded.
There is a function, supported on the 3750s called the IGMP querier function which allows the switch to make IGMP queries per vlan without PIM enabled. We may be able to use this but i have absolutely no idea how it will work with the L3 multicast routing config.
I recommend you try and get multicast routing working first. If you can get to the stgae where you can send a multicast stream from one vlan to another then you should be able to use wireshark to then see each port in the destination vlan receiving the stream (even when you don't want it to).
If you can get to that stage we can then try the IGMP snooping querier to see if we can restrict the stream to only those ports that need to receive it. It may be we can't in which case -
a) you could statically configure the multicast mac address to the relevant ports but this is no scalable and does not allow clients to dynamically join and leave the multicast group
or
b) simply allow the stream to be flooded to all ports within the destination vlan. Not ideal and kind of defeats the purpose of multicast but you may have no choice.
I doubt whether any of this would be supported by Cisco though as i think their position would be to simply upgrade to an IP Services license although in understand this may not be possible for you because of cost.

How do I check a wifi network on my iphone 4S ?

I was in a Dennys restaurant that boasts a free WI-FI network, but couldnt logon to it. The iPhone saw the net but would not join it. No-one else could get onto the network either. This has happened in other locations too.
My home network is via the Telus phone line. I noticed that on this network, according to Speedtest.net, the internet speed is not very good, i.e. download 5.96 MB, Up 0.43 Mb/s, ping 62ms
Thanks for any ideas on making it easier to join free networks that wont be joined, and speed up access on a slow networks

If others are having problems getting on the network, it's probably a problem on the network, but I think you understand that. If the network is broken and it doesn't belong to you, the only way to 'bypass this' is to disconnect from the WiFi network and use 3G. That or complain to the manager... I doubt that will do you much good. They can barely figure out how to fry eggs, much less do anything with their network.

Why has my native windows 7 Pro-64 network to a windows 7 Pro-64 VM has slowed to a crawl and freezes, after the new Arris cable modem was installed?

Please appreciate the details, so the complete situation can be visualized:
The office network:
New Mac Mini PC running Win 7Pro 64, (in boot camp), networked to an iMac running the same Win 7 Pro 64, VM, UNDER Fusion 7Pro.
To review: My treatment rooms former dell PC/running vista business/ running the server and network versions of my Dental practice mgmt & X-ray capture apps, had no probs WLAN to the front desk iMac running the same PC client dental network apps under the same vista business, & Fusion 4. The dell slowly fried its power supply .
I could not wait to replace it with a Mac mini/ boot camp/ win7 pro 64 bit, as it has to run natively to capture X-rays. The front desk iMac was also upgraded to os10.10.3/ Fusion 7pro/ and its own matching Win7 pro 64bit. The iMac is wired and WLAN connected to a netgear d600 router and a Time Warner Cable modem. The modem then failed and was replaced by an arris modem. As the Arris was configured out of the box, the network ran much slower slowed, as compared to the original modem. BUT- The Vonage 2 line phone system stopped working- no incoming or outgoing voices could be heard after it rang. Then twc remote configured it and the phone now works, but the network iMac slowed to a crawl, and now freezes when accessing the Mac Mini PC dental server to edit or enter data. The Mini perfectly accesses the internet via wifi. It accesses the front desk canon printer by wifi, and can print share they the iMac that is wired to the printer, as well, BUT, the network connection is a spinning pinwheel. The front desk imac easily finds the Mac Mini PC server on the network. It connects easily by entering the servers IPv4 address SHOULD THAT last value change. But if data isn't entered in slow motion, the window and app freezes, and has to be force quit by Task Manager!
Cause:
1. I think TWC switched the cable modem from the default- Non Bridged, to Bridged mode. Could this be the cause?
2. The network setting in fusion, on the iMac is auto detect, a setting that always worked with vista and with the new Win7 system, before TWC installed the new arris modem. 3. Switching to NAT does not work at all is there a different setting to use?
3. Does the Netgear Router have to have a port or pref configured so as not to block the Server.
4. might in need an Access Point (I have an extra netgear wdr3400) ).
5. Do I need an Extender that plugs into the AC LINE?
I hope this info helps.
PS:(some addtl info:
1. File sharing works fine between the minis -Mac and boot camp sides and between the iMacs- Mac and VM sides and between eother side to or from either of the 2 computers! 2. Also either office computer and all of my my home macs , (& my iPad, & iPhone), can access each other instantly and flawlessly, with splash top streamer and jump desktop remote apps, as controller or as client! In fact, the front desk iMac can remote control the mini PC AS IF YOU WERE DIRECTLY ENTERING INFO I TO IT!
SO I think it's either a misconfiguration in the TWC cable modem &/or some additional pref to config in the router? Thanks so much for your help, (been using VM's since VPC1. & Win95 in a iMac, 1999, DV MODEL! (TWC BLAMES VONAGE FOR NOT OPENING SOME PORTS IN THE TELE MODEM. Vonage blames TWC FOR NOTopeningj ITS PORTS IN THE CABLE MODEM, when they meant the ports on the Netgear. They have passed the buck for 6 weeks with not even a guess at what to do. VERY FRUSTRATING! Again, thanks to all!

Okay Saint Steven, I'll bite:
I read your description multiple times, very carefully, and I am still confused. May I suggest the following:
* Follow basic troubleshooting procedures. Isolate each individual problem. Don't try to get everything working at once. Make one change at a time.
* If I read your description correctly, the Netgear D600 (??) Router is the office LAN (not WLAN). Connect each piece on the LAN separately one-by-one, and test each piece individually. Get your LAN and its devices working first. Forget about the Vonage and the Arris Cable modem.
* Next, look at your Internet connection. Again, try each piece separately. Depending on how the original cable modem and the new Arris cable modem are configured, you may also have to adjust the configuration of the Netgear D600 Router.
* Finally, if you are still having problems, try to organize your thoughts and presentation before you post again. List each element in your network. List how each element is configured. Be systematic.
"Arris cable modem" does not help much - some are simple bridges, others are routers, etc.
To answer your questions:
1. I can't tell from your confusing description, but I don't think so. It seems like the problems are associated with the system changes you made (replacing Dell, etc.) and the problems seem to be isolated to the local LAN.
2. Auto detect should work, but it is easy to change and test, as long as you change one thing at a time.
3. No. The Netgear router should allow all communications on the local LAN. Could you have put the "server" in the DMZ?
Note: I could not find a Netgear "D600" model in a web search. Do you mean N600?
4. No. I doubt that you need an additional access point. Based on your description, everything appears to connect to the LAN.
5. No. See 4.
To repeat myself:
* Do careful, systematic troubleshooting.
* Provide carefully written, detailed description of your network and system configurations when you ask for help.
Good luck!

[SOLVED] network randomly doesn't work after reboot (e100)

Hi
Lately I have some weird issues with network. I shutdown computer during night, so basicly I reboot it at least once per day and every now and then without any pattern network doesn't work at all and so far only solution I have found is to reboot (again).
Before anything else I'm sure it's not hardware problem, since other OS on same computer don't have any issues, neither is router since other devices in network from laptops to mobile phones work flawless.
Relevant info and what I have found so far (not everything is copy/pasted so there may be some typos):
$less rc.conf (network part)

So basicly network is dead, can't even ping router, cable connection is detected tho (lights are on). I have tried to restart newtork with /etc/rc.d/network stop/start, nothing. Only clue is dmesg.
$dmesg

modrope -r e100 and then reloading it doesn't help either, but reboot does (once I had to reboot twice tho).
Anyone with more clue and ideas then me, it's getting really annoying, it also kill whole KDE plasma-desktop for couple of minutes before plasmoids find out network is really down and I'm not really fan of morning "gamble". I can't pinpoint some hard date/update when this started to happening because like I said it's random but last couple of months should be quite accurate. Thanks in advance.

I don't have anything special set at router but I doubt rc.conf play any role. I will try to set it up with dhcp (but I think I have tried that already) if there is any change.
This morning I had to reboot twice, so new kernel didn't help. Fowler, what network card are you using, also e100 (well or some intel)? I dunno, should this be handed to the kernel team? If it will piss me enough one morning I'll just go and buy a new network card, just wanna be sure that will really solve the problem.
UPDATE: OK, this is just silly. I remebered I have acctualy onboard LAN so I edited rc.conf and dived into the dust under my desk to move cable and there I found out it was acctual onboard in use all the time Now this dosen't make much sense to me anymore, when I can't get net up all the stuff in dmesg is e100 related. Anyway, I connected network to e100 and rebooted, suprise, same story. Dmesg reported again link was not ready. I edited rc.conf to
INTERFACES=(eth0 !eth1)
in case this has anything to do with proper timing at assigning whatever needs to be assigned to network cards at boot so I'm sure just 1 card with all info provided get's kicked in at boot. First reboot after that works, it dosen't prove anything yet but at leat it's some kind of progress in recognising proper cause.
UPDATE 2: Nah, still happens. Googling for "no link during initialization" show a lot of familiar problems, almost all on nforce motherboards and mine is nforce too. I just don't get it why this mess seperate PCI network card. In any case it's extremely annoying.

Cannot detect any wireless networks on my HP ENVY TouchSmart m7 j120dx

Hello,
My laptop won't pick up any wireless networks at all - I'm having what seems like a few different problems:
1. Because the laptop won't pick up any wireless networks, I can't of course connect to the internet without using my ethernet cable.
2. When I try to turn my adapter on using the F12 key, all it does is toggle airplane mode - which isn't going to help me connect to the internet.
3. When I go to 'Network' under PC Settings, I can toggle airplane mode but the bluetooth is greyed out and can't be toggled and it doesn't even give me an option to turn back on my wifi adapter.
4. When I went into the Network and Sharing Center to enable the adapter that way under 'Change Adapter Settings', I couldn't even see the adapter listed there. All it showed was Ethernet and Hamachi because I use LogMeIn Hamachi on my computer.
By this point, I was like "Oh, great - the adapter might somehow not even be there even though it was last night," (I was online wirelessly the night before) so I went into the device manager and then expanded Network Adapters I only saw the same two Ethernet and LogMeIn adapters.
5. So next, I tried downloading the adapter - but the problem is, I have no idea what kind my laptop is supposed to have. Going to the download drivers section in the support area of the hp website, I found many options and none of them seemed to work. I also tried redownloading the Wireless Button Driver (whatever that's called) and that didn't work.
5. I even tried doing a system restore to a point of about a week ago - this also did not solve my problem because the same things were happening and the same things I tried above still are not solving the problem either.
I know countless other people have had the same problem(s) mentioned above (simple Google search told me that) with their HP ENVY Notebook PCs, so I'm hoping that someone can help me and finally solve this problem for me.
The model is HP ENVY TouchSmart m7 j120dx, the model number is E8A11UA#ABA, and my computer is running Windows 8.1 64-bit.
On another note, here's the names of the only 2 adapters that show up in my device manager list (one is for LogMeIn Hamachi);
Realtek PCIe GBE Family Controller (Ethernet)
LogMeIn Hamachi Virtual Ethernet Adapter (Hamachi)
The wireless was working fine before with Hamachi installed, so I doubt that has any significance.
If there's any other information you need that I did not mention above, feel free to ask me. I look forward to someone replying as soon as possible and being able to find a solution to this problem for me!
EDIT: One other thing I should mention is that the wifi in my location is working fine for every other device I try (phone, gaming console, other people's laptops/desktops, etc.

Hello dginther,
Welcome to the HP Forums!
I understand wireless is not working properly. If the issue just began occurring, I would perform a system restore. I want you to bring the computer back to the earliest restore point possible, in an attempt to dodge whatever caused the issue. Here is a document on how to perform a System Restore: System Restore
Next, please try the steps in this HP document: Troubleshooting Your Wireless Network and Internet Connection (Windows 8)
These steps should be enough to resolve the issue. If not, you can try a manual reinstall of the driver:
1. Go into Device Manager, then Network adapters.
2. Right-click on the wireless driver, and select "Uninstall".
3. Restart the computer. This will force the driver to reinstall itself.
Please let me know the results of your troubleshooting. Thanks!
Mario
I worked on behalf of HP.
