Question about networking config

Hi all
i am about to setup a remote server with arch and i was wondering if the following rc.conf entries will work.
eth0="eth0 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx"
eth0:0="eth0 yyy.yyy.yyy.yyy netmask xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx"

I think you need
eth0:0="eth0:0 yyy.yyy.yyy.yyy netmask xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx
, and you need
INTERFACES=(lo eth0 eth0:0)
in your rc.conf.
but it should work...

Basic questions about Network Licence

Hi,
Before buying, I have some basics questions about the network licence of Acrobat
As an example, if I buy 5 network licence for 20 users.
If the 5 licence are used or if one user is outside and can't access the licence serveur, is there still some basic features available? I mean, is there a "acrobat reader" part that still allow users to read pdf?
In the same kind of problem, if 10 users are using Acrobat just for reading pdf file and that a user now want to use acrobat to create a pdf, is there still available licence or the 5 firsts that are just reading have take the 5 licences available?
Thank you for your answers

Questions about networking a desktop app

So the background first: I'm working on a hobby program, and wanted to try my hand at networking it. It's a desktop app (a simple game) that two or more users can play at the same time. There's no centralized server to connect to, it will be an ad hoc connection. One user hosts a game (starts a server) and then others join the game (start their clients). I've done a lot of research, but still have some unanswered questions. I plan on using ssl encrypted socket connections. I used this tutorial to learn about trust managers and such.
My questions are:
1) What's the best way to give the users the info they need to connect to each other? I haven't looked into it yet, but I'm assuming it's not to hard to display the server's ip address, which they can give to the clients to connect to the server. PC games used to do this years ago before companies began hosting matchmaking services. Is there more required than that?
2) What's the best way to pick a port number that all user's have access to? I know I need to pick a port that isn't registered by another app, and that the port number will need to be given to the clients along with the server's ip. If the server is able to open that port, is there a situation where clients wouldn't be able to access that port?
3) Since this is basically a toy, I don't want to to the trouble of something like Verisign for security. Will a self-signed certificate authority be adequate? My concerns are not opening user's computers to attack, and protecting the data in transit. I know ssl will protect the data, but I'm not knowledgable with security to be sure if a shared trust manager will be enough to only let the app access the connection. What are the risks of someone bypassing the security and gaining access to our systems?
I've never written an application that had to deal with network security, so please pardon my paranoia, and thanks very much for any help.

If you are getting the week or intermittent wireless connection then,try the following settings on the router...Under the Wireless tab,Change the Channel Width to 20MHz and Channel to 11..Provide unique SSID.Under the Advanced Wireless Settings..Change the Beacon Interval to 50,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings...Power Cycle the network and check the connection.
WPA2 is very secured Secured type,so it is advisable to use it.However,it is not necessary to use WPA2.
If you are using "N"Router then,to get the full advantage of N Speed,you should "N" Adapter.
If you want to set the static DNS on the computer or any other wireless device then,you can set any DNS numbers.
To repeat the wireless signal of the N Router,I would suggest you to go for an Access Point like WAP610N.

Question about Network In/Out in the Monitor of the Cloud Service

Hi there
My question is that what kind of data is the monitor monitoring? The monitor is in the cloud service.
And what are network in/out in the monitor stand for? The network in/out are in the monitor.
The monitor had monitored a huge amount of data in my cloud, but I have no ides what are they.
Thanks a lot!

hi Tianchi,
Thanks for your posting!
>>what kind of data is the monitor monitoring? The monitor is in the cloud service
From the concepts side, By default, minimal monitoring is provided for a new cloud service using performance counters gathered from the host operating system for the roles instances (virtual machines). The minimal metrics are limited to
CPU Percentage, Data In, Data Out, Disk Read Throughput, and Disk Write Throughput.
If you want to monitor other metrics, you could use the azure Diagnostic to custom
performance counter in your cloud service or set
Verbose setting on the azure portal. For this issue, I suggest you could refer to the concepts part of this page (http://azure.microsoft.com/en-us/documentation/articles/cloud-services-how-to-monitor/
>>And what are network in/out in the monitor stand for? The network in/out are in the monitor.
Base on my understanding, Network in/out include the
performance counter "Bytes receive" and "Bytes send". Maybe it seems that your data size of network in/out is huge amount. But only your outbound data
can be charged. Of course, if you have some doubt about data or data billing, you could contact Azure Billing support for more details.

Question about networking iMac and streaming video to TV

I have the 24" iMac 2.66GHz with 4 G ram. Currently using Motorola SBG900 (Docsis 2) cable modem & router to stream Comcast through house (another PC, iPhones, LG Blu Ray player/digital video streamer).
Recently acquired a Netgear Rangemax 3700 which is supposed to be the fastest current wireless router. Here are my questions:
1) Can I just use the Motorola SBG900 as modem ONLY and run the ethernet out of it to the Netgear router (thus bypassing the router built into the SBG900). Will this accelerate the streaming of video to other receivers?
2) Would I be better off with a Motorola 6120 Docsis 3 Cable modem feeding the Netgear router (even though my Comcast cable feed is Docsis 2, not 3)?
3) Since my Comcast account is rated 10 Mbps max (though it sometimes goes up to 15 or so late at night) and I believe the existing Motorola SBG90 is rated at 54 Mbps, is the limiting factor the speed of my Comcast connection and all else doesn't matter? That is, is it impossible to speed up my streaming or download speed without a faster connection to the Internet?
4) What kinds of connections are there that are faster than Comcast cable connections?
Basically, I don't want to waste money or time if I'm already at the maximum throughput available given my connection. If I can get marginal speed increases by adding new modem and router, that's fine. I'll do that.
Thanks for your help.
PS: I owned and returned the Airport Extreme Base Station. It did not increase the speed of my connection or streaming, but then it tested very poorly at www.smallnetbuilder.com -- about half the speed of the Netgear Rangemax.

Can't help with Q 1 + 2, but here are some things to consider re:
+3) Since my Comcast account is rated 10 Mbps max (though it sometimes goes up to 15 or so late at night) and I believe the existing Motorola SBG90 is rated at 54 Mbps, is the limiting factor the speed of my Comcast connection and all else doesn't matter? That is, is it impossible to speed up my streaming or download speed without a faster connection to the Internet?+
My Comcast account is rated 15 Mbps and I never get that. I've done everything I can here including Cat 6 cables (instead of Cat 5), but the major problem/hangup in my case is: Comcast is using 20-year old buried cables from their hub (approx. 10 mi across town) to the neighborhoods here - those cables are "leftovers" from the company Comcast purchased the rights from. So, we not only have old cables, but the little boxes all over the neighborhood feed at least 6 - 10 homes each, so you are sharing the available bandwidth with the neighbors. And, whenever everyone seems to be online at the same time, my downloads slow down to a c r a w l (as slow or slower than dialup occasionally!).
So, unless you have a better/newer cable setup where you are, you need to keep that in mind; in that case, no matter what you do, you are at the mercy of Comcast's equipment and your neighbors' usage.
4) The only one I know of is FioS (fiber optic).

Question about network statement in OSPF and BGP

The network statements in OSPF and BGP can be used to advertise networks. But I'm not clear under what circumstances would make more sense to use network statements to advertise a network than by using other methods to have the network learned by other routers.
Here is an example: assume I'm running BGP on router A. I want to advertise network 10.1.1.0/24 to other BGP peers. I have a OSPF route for this network. I can do 2 things: one is to use "network 10.1.1.0 mask 255.255.255.0", the other is to do "redistribute OSPF ... route-map OSPF-INTO-BGP", and create a prefix list to permit 10.1.1.0/24.
Both would work to have this network learned by other BGP peers. But which is better for what purpose?
Thanks a lot
Gary

Hi Gary,
There is one little difference between the use of the two approaches - the route injected into BGP by using a network statement will carry an Origin attribute of IGP, whereas the route injected using redistribution will have an Origin attribute of Incomplete. Now, that is not a huge issue since you can always change that whatever value you desire both with the use of the network statement and redistribution. The important thing, however, is that in the BGP best path selection process, the Origin attribute comparison is fairly high up and will prefer a route with the attribute of IGP.
Apart from that, there is absolutely no difference between using the network statement and using redistribution with a route-map that matches exactly on the same route that you would have specified with the network statement.
I guess one advantage of using the redistribute approach is that it does not clutter up the BGP config. If you wish to add more routes, you simply add them to the prefix list so that you don't really touch the BGP config portion at all..
Hope that helps - pls do remember to rate posts that help.

Question about networking

So I've gotten placed into the role of UCS manager having only a basic understanding of upkeep (currently taking training). I've noticed some things that I'm curious about but don't know where I should look for more information.
For one. We were orinigally using port channels to do networking when we had a 1g connection to the core from the FI, now that we're 10g my network team told me that we wouldn't do port channel anymore and what I've got currently setup is 3 connections marked network and 1 connection marked unified uplink 2 Network in FI B and 1 Unified Uplink and 1 network in FI A.
This seems very incorrect to me but I also can't seem to set the unified uplink port back to a network port (I don't see that as a configure choice).
If anyone has some good info on what I really need to be looking at that'll be great but if you've run into a similar issue that would be awesome.
Thanks

Sean,
Doing a deeper research in our data base I found that this has no problems and actually is saying that it works as uplink port for FCoE and Ethernet at the same time and it should show up under the LAN and SAN tab as uplink ports.
We set the role of the port to either "Network", "FCoEUplink" or "UnifiedUplink" based on whehter the port is used as an ethernet uplink, fcoe uplink or both.
If you go to the LAN/SAN tab and check the interface you should be able to see the interface as uplink for both as these are Unified Ports that can be FC or Eth ports.
Can you try to unconfigure the port from the "Equipment" tab? the LAN/SAN tabs will only let you delete/disable the interface, and then just configure it as LAN OR SAN uplink?
Let me know what happens.
Rate ALL helpful answers.

Question about Network (JNet)

Dear experts:
I use Network in my WebDynpro program, in the graphic, first node (A) act as a container, it contain two other nodes: B and C. I found that B and C displaied vertically in A, but I want them are horizontally displayed in A. Anyone know how to do that?
Thanks.

If you're talking about round robin DNS, then no.
DNS is completely blind as to the state of the servers in its table.
Sure, you can say that your server has two IP addresses, and BIND will happily hand out both addresses to each client, effectively splitting the load between them, but if one of the servers goes down BIND has no way of knowing that and will continue to offer the second IP address as valid, even if users can't get there.
There are load balancing technologies available that will automatically failover connections from a failed server, but they tend to cost $$$ (or, at the very least require running a separate 'traffic cop' server in front of your real servers and if that goes down then all bets are off).
That's not to say you're out of options altogether. It's possible to configure Mac OS X's IP Failover - a system that automatically kicks in when a partner server fails. You could use this to take over the second machine's IP address and start up services as soon as the partner fails - users would continue to connect to the hostname they're familiar with, but behind the scenes that IP address has moved to a different box. This is covered in the Mac OS X Server docs - look for IP Failover.

Question about network simlocks and countries

No, I'm not asking how to unlock the phone, as that would be unethical. (Whether or not it is illegal is an interesting question, but not one I'm prepared to venture into here.)
A friend of mine has a phone that is simlocked to Orange in the UK, and I'm contemplating buying it from him.
However, even though I'm with Orange, I live in Switzerland.
Will a phone simlocked to Orange(UK) work with Orange(CH)?

The simlock information stored in the usually specifies network operator and country. The phone may ignore the country setting if the operator information is correct but I wouldn't bet on it!

Question about MaxDb config files

I have a problem where a database is taking 28 hours to backup.
While the db backup runs, the log backup will not.
I want to know if there is a way to get around that; either by specifying a unique set of configs so temp file names won't conflict and 2 backups can run simultaneously or some other way.

Let me recommend using the 'Database Analyser' for this. In an SAP environment, this tool autostarts and collects data every 15 minutes (default interval). The data itself is kept in one 'dban.prt' log file plus detailed info in various Excel style csv files.
If you have an SAP system nearbei, you could integrate the MaxDB you want to monitor via TA DB59 or use DB50/LC10, if MaxDB is running in an SAP system. Of course, you could also just look at the csv files directly, but they are much easier to use within the SAP world.
Please have a look at our FAQ note 1423935 for further details.
This means in regards to your specific question: Start the Database Analyzer (if not already active) and go to the 'DBAN_FILLING.csv' file. There you will find the filling levels for temporary and permanently data plus min and max values and averages...

[SOLVED] Question about network setup static and dynamic

I am trying to set up an Arch install on my other pc. I have used Ubuntu and then Linux Mint for a year+ and Arch has always intrigued me so I am attempting to install it now. I do consider myself a pretty advanced computer user/programmer but computer networking has always confused me a little. I'm not quite understanding whether I setup my network with a static or dynamic ip. This is what I know
I have a static ip assigned to me by my ISP but I do have a router so it assigns me a different internal ip. Does that make my ip dynamic?
Last edited by c26zwj (2013-03-14 18:24:35)

If your ISP assigns a static IP then your IP in the internet is static. If you have a different internal IP then your router is running a DHCP server and performing network address translation. Your IP on the LAN is dynamic (unless you configure your router to assign static IPs, which can be useful if you want to forward ports to a specific computer). You most likely want to use DHCP to obtain a dynamic internal IP when you connect. The external IP is beyond your control (it is managed by the ISP and assigned to the router) so you do not need to worry about it.

Question about struts-config.xml

Hi,
In the struts-config.xml,
What is the difference about "redirect="true" and redirect="false" ?
thanks,
happybaobao

Hello,
redirect = truemeans that the ActionForward () statement in your execute method of the Action class will perform a response.sendRedirect. You can see that the URL is getting altered in the clients browser
redirect = false means the vice-versa.
I would recommend that you go through the Struts official site and see the DTD specifications in the URL

for more details.
Thanks and regards,

Documentation needed about networking config storage environments

Hello,
In my job there are more and more environments where I have to manage storage switches in vmware ESX environments with Netapp storage.
I was wondering if there is any documentation available about how to configure storage switches in these environments. I have checked with vmware, but with no luck.
Any help is appreciated. Thank you and kind regards,
Ralph Willemsen
Arnhem, Netherlands

Ralph,
although it is not mentioned what is the type of switch connecting storage.
I am assuming it is cisco MDS storage switch..
here is the MDS switch configuration guide
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/sw/4_1/configuration/guides/cli_4_1/ov.html
If you are looking for configuration of storage devices itself. that has to come from either VMWare or Netapp.
This support forum is perticularly focused on Cisco MDS/Nexus switching side.Are there any issues..configuring / attaching these devices on cisco switch side?
when you connect any server running Vmware ot netapp storage device on MDS switch. there is nothing special required on port side. Device is suppose to negotiate automatically with switch port and it comes UP or online state.
First thing you need to see .. Is the Port UP.. if Yes, switch side is good.
second is zoning. create zones for required devices to be zoned together and activate.thatz it..
rest all of the configuration is on Device side..means on VMware or Netapp device side .How you allocate disks/Lun/volume etc ..these things are outside of switch configuration,.
Have you opened a case with Vmware or Netapp or posted question on these vendors Support site.
Hope it gives a right direction.
Have you

General questions about network setup

Hi everybody,
I am in the process of migrating the network of our small nonprofit-organization from windows to linux. I searched for a while and had a look at several distros but it seems that arch is what we need ;-) Some months ago I migrated my own laptop and desktop at home to arch and learned a lot about KISS since then. But now I need some hints that point me in the right direction. The net consists of a router (running fli4l for firewalling, ntp, dhcp and dns-server), a main Server (SuSE 9.1 samba domain controller by now) and a backup server (arch). There are some workstations running Win2000 or XP and two arch systems with a KDE-desktop.
How can I manage single sign on for all these machines? NIS seems to be insecure, LDAP very complicated. Any other options? Maybe someone with a working configuration as an example? The setup should take care about the possibilty of one server going down and the backup server then taking all services over.
On each windows machine I needed antivirus and desktop firewall software. Any need for this on linux machines? I am a bit concerned about degrading performance since all workstations are 1GHhz Durons which is not so much these days...
By now the main task for all workstations is doing some text processing and spreadsheet work. The servers do the file sharing using samba. In the future I want to set up an internal email server, maybe some kind of networked PIM-Software for all users. What would you use for this purposes?
Are there any other things I have to keep in mind while setting up a small network like this?
Thanks for your help.
Harvey
BTW, English is not my native language so don't shoot me if I put something wrong ;-)

TB2 wrote:If the main tasks are text processing and spreadsheet work, then why are there any Windows machines?
Because this environment has grown over years and is now moving towards Linux. And there is some special software that only exists as windows software (medical databases) which I was not able to run in Wine. Virtualbox is a good hint, though I am using vmware in the moment for my own boxes. So vmware-player would do as well, I guess.
Then you will also be able to drop samba...
Mmmh, I'm a bit concerned about that. I suppose you suggest using NFS/NIS? Isn't that believed to be insecure?
and there's loads of IPM programs for Linux
Well, not so much if you are looking for a networked one which archlinux supports. Evolution looks nice though I'd personally prefer Kolab, but for groupware features it needs a server which I wasn't able to find in the repositories. And making packages is not one of my skills...
switch from KDE to a more ressource-friendly DE, like Xfce, Window Maker or Fluxbox.
Tried XFCE, which looks nice, but I need a login manager for my users. Had a look at slim, but was not able to configure it right. The wiki seems to be outdated here. It runs on boot, but never lets me login. I come back to the login screen in an infinite loop. Still looking for a solution here.
In general I think it's better if all machines run the same setup. Mixing Win2000, XP and Linux machines can be done, but I think it's not recommended
This is what I am thinking too. And I want to migrate, but in the moment there are some caveats I have to deal with.

Question about network w/two routers

I am trying to setup a network that covers both my home and detached garage home office. The garage office is approximately 100 feet away from the home. Internet access is delivered to the garage office. The cable modem is connected to a wired router with four switched ports. A cable from one of the switched ports extends through an underground conduit into the home where it attaches to the internet port of a Linksys WRT160N wireless router. I can access the internet from the garage and within the home, but I CANNOT browse from the home network to the garage network.
How can I configure the Linksys WRT160N so that I can access the internet from both locations AND browse from one network to the other?
Thanks,
Mike208

With this setup.
