No internal Interface for Corp Wireless?

I have been trying to create a Guest WLan on my 4402 WLC system and have found several confilcting documents explaining the procedure. During this process I have notices that although the current corp wireless works, there was never a virtual interface created for it. Instead it uses the same Wlan/Vlan as the ap manager and managemnt interfaces. Could this by why I cant seem to get the Guest access working? or is this not a problem after all since the wireless does work.
Any advice would be appreciated, would love to take a class or something on this, good stuff but there seems to be alot to it.

Hello Robert,
It is OK to use the management interface as your internal wireless network interface as long as you are OK with that design (clients and management in the same subnet).
Basically, if you want to put WLAN traffic in a different WIRED vlan, you create a dynamic interface for the desired VLAN (controller > interfaces) and then select the desired interface under the WLAN configuration.
On the switch side, you will need to make sure that these new vlans are being trunked to the WLC.
The following diagram explains the interface usage on the WLC platform:

DO i need some extra hardware interface for receving both Audio and video

hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for receving both Audio and video. im using code AVTransmit and AVReceive found from this site only
After running TX
i give Dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting

[solved] Arch linux access point with multiple interfaces for the NAT

Hi, I have a router running Arch linux. It is connected via LAN (let's call it eth0) to the internet. It has a second LAN interface, eth1, and a wireless interface in master mode, wlan0.
Now, Everything works perfectly except providing network connectivity on eth1 and wlan0 simultaneously. I followed the guide in the "Internet share" wiki article and use dnsmasq/hostapd for the AP. It appears as if all traffic from the router is sent to the wlan0 interface, even if it came in through eth1 (for example, dhcp requests). I cannot really find information how to solve this. The words "bonding" and "iptables" are floating around, but there is not really an easy to understand tutorial for this.
What do I need to do to use both the eth1 and wlan0 interface (for different clients!) on my router?
Best regards, and thank you in advance
Jan Oliver
/e: This seems to be my problem: http://www.novell.com/support/kb/doc.php?id=7000318 How do I solve this using the usual iptables? (The way described in the article doesn't work: "RTNETLINK answers: No such process" errors.)

Or you could bridge eth1 and wlan0, and make dnsmasq bind/listen on that bridge...

Adaptation of LIFA (LabVIEW Interface For Arduino) to other Arduino compatible boards

Hello evryone,
I am trying to use a ''Sakura board", which is an Arduino compatible board, having similar programming as Arduino. This board is manufactured by Renesas; more specifications on it can be found on the following link: http://sakuraboard.net/gr-sakura_en.html
What I would like to know, is if the firmware used for LIFA to interface Arduino with labview, or the ChipKit firmaware, can be used to this kind of Arduino compatible boards.
My aim, is to use the Sakura Board for acquiring signals from various pins(Be it digital or analog), and setting other pins (Digital) parralelly, using labVIEW, as this is done using LIFA, or LabVIEW interface for ChiKit!!
Thanks in advance for your support.

I haven't had any experience with the Sakura board, so can only go on the information on the website.
I've used the Arduino LabVIEW interface previously, and it basically uses serial communications between the PC and the Arduino. This serial interface is provided by the on-board USB-serial converter (an ATMega8u2 running custom firmware).
From what I can tell about the Sakura, it appears as a storage device when plugging into a PC, and doesn't seem to have a USB to serial converter. If this is the case, then the LIFA toolkit won't work. That said, my understanding of the Sakura board may be incorrect (for example I'm unsure what operation modes the slide switch changes between). If you can confirm it has a USB-serial port then LIFA may work. I guess the key thing is that the serial port is required.
You may be able to use a software serial port (http://arduino.cc/en/Reference/SoftwareSerial) on the Sakura to communicate with a PC, though that would require a PC with a serial port, or an external USB-serial converter. This approach would also require you to modify the LIFA arduino code (located in vi.lib\LabVIEW Interface for Arduino\Firmware\LIFA_Base) to reference the software serial port. It's probably a long shot that this will work, as the software serial library has been written for AVR chips, making use of their specific internal timers.

[Solved For Now] Wireless Not Working on HP Pavillion 15-n278sa

EDIT: I seem to have fixed it for now by following this tutorial, I don't know how long it will last though: http://askubuntu.com/questions/337785/w … -c55-a5281
Hi there guys,
I have been having some problems with my Wireless under arch on my lapotop, which is a HP Pavillion 15-n278sa. I've had the wireless working twice before, but a reboot broke it both times. The Ethernet works perfectly fine. The first time I have no idea how I got it to work, it was a combination of a bunch of different threads and eventually I modprobed the wireless adapter and it worked (this no longer works).
This is the output of when I try to connect to the wireless using wifi-menu:
Job for [email protected] failed. See 'systemctl status [email protected]' and 'journalctl -xn' for details.
So I run systemctl status [email protected] and journalctl -xn and this is the output of the both respectively:
Systemctl output:

This one being the wireless controller:

If there is anything more I can provide I would happily do it, I really need the wireless to work under this laptop. I know it works, I have had it working under Arch and it works under Ubuntu no problem. I am not sure if it is a driver problem, or if it's a problem with netctl. It looks more like a problem with netctl as after netctl updated it started working, and after a reboot it broke again.
Thanks so very much everyone,

How can I know if my new internal hd for macbook pro is compatible?

I have been trying to upgrade my internal HD for macbook pro early 2008 2.4 and have been having a hard time getting it to boot. Problems with both WD and Seagate. I am wondering if the problem is with Mavericks. I got a good back up from Time Machine to load on the hybrid drive. Then when I try to restart it shows the apply symbol with no chime and then a black screen comes over the blue screen with some code (strange problem I have never seen) I can see that all the data is on the drive. I was able to partitian in disk utility. Anything ringing a bell. I have done several switches like this and this is the first time I have had so much trouble. I reinstalled my old drive just to make sure there was not another hardward issue and everything is fine there. In fact I have a new logic board freshly installed by mac.

Your machine has a SATA 2 interface and I'm sure the new drives are SATA 3. They should still step down and work though. It's possible your SATA cable is marginal and the newer drive is trying to demand more out of it than the old one did. A good test would be to put the new drive in an external enclosure and see if it works ok from there. If so, it's probably the cable.

How did you install Mavericks on the new drive?

Best Practice for FlexConnect Wireless roaming in MediaNet environment?

Hello!
Current Cisco best practice recommendations for enterprise MediaNet design, specify that VLANs be local to a switch / switch stack (i.e., to limit the scope of spanning-tree).
In the wireless world, this causes problems if you want users while roaming to keep real-time applications up and running. Every time they connect to a new AP on a different VLAN, then they will need to get a new IP address, which interrupts real-time apps.
So...best practice for LAN users causes real problems for wireless users.
I thought I'd post here in case there's a best practice for implementing wireless roaming in a routed environment that we might have missed so far!
We have a failover pair of FlexConnect 7510s, btw, configured for local switching for Internal users, and central switching with an anchor controller on the DMZ for Guest users.
Thanks,
Deb

Thanks for your replies, Stephen and JSnyder.
The situation here is that the original design engineer is no longer here, and the original design was not MediaNet-friendly, in that it had a very few /20 subnets bridged over entire large sites.
These several large sites (with a few hundred wireless users per site), are connected to an HQ location (where the 7510s in failover mode are installed) via 1G ethernet hand-offs (MPLS at the WAN provider). The 7510s are new, and are replacing older contollers at the HQ location.
The internal employee wireless users use resources both local to their site, as well as centralized resources. There are at least as many Guest wireless users per site as there are internal employee users, and the service to them consists of Internet traffic only. (When moved to the 7510s, their traffic will continue to be centrally switched and carried to an anchor controller in the DMZ.)
(1) So, going local mode seems impractical due to the sheer number of users whose traffic bound for their local site would be traversing the WAN twice. Too much bandwidth would be used. So, that implies the need to use Flex / HREAP mode instead.
(2) However, re-designing each site's IP environment for MediaNet would suggest to go routed to the closet. However, this breaks seamless roaming for users....
So, this conundrum is why I thought I'd post here, and see if there was some other cool / nifty solution I wasn't yet aware of.
The only other (possibly friendly to both needs) solution I'd thought of was to GRE tunnel a subnet from each closet to the collapsed Core / Disti switch at each site. Unfortunately, GRE tunnels are not supported in the rev of IOS on the present equipment, and so it isn't possible to try this idea.
Another "blue sky" idea I had (not for this customer, but possibly elsewhere in the future), is to use LAN switches such as 3850s that have WLC functionality built-in. I haven't yet worked with the WLC s/w available on those, but I was thinking it looks like they could be put into a mobility group, and L3 user roaming between them might then work. Do you happen to know if this might be a workable solution to the overall big-picture problem?
Thanks again for taking the time and trouble to reply!

Do I need a router to interface with my wireless laptop and printer, or can booth tooth.

Im having a problem interfacing the HP B210 all in one wireless printer to my ASUS wireless Laptop. Do I need a router or can I some hoe make the wireless connection using my blue tooth on my laptop. Please help.

Well, the printer does not have bluetooth so that will not work.
However, you can connect to it directly via wi-fi on your laptop. From the front of the printer go to: Setup > Network > Restore Network Defaults.
Now, on your PC, look for a wireless network beginning with "HP". Join it. There is no password.
Now, go to Control Panel > Printers and Add a Printer.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Hard drive interface for new dv7t-7000 quad

Hi.
I just want to know the hdd interface for the newer ivy bridge dv7t-7000 quad laptops.
Does anyone know if it is SATA, SATA 2 or SATA 3?
Thanks

I run three firewire audio interfaces daisy chained together, 2 Presonus FP10's and an Alesis Multimix8.
This gives me 24 simultaneous inputs. I normally record 24 bit at 88.2 . My iMac has a FW800 and a FW400 port. What I tried to do was run all the interfaces through the 400 and record to a FW800 external hard drive but I it kept dropping out interfaces, even if I used only one interface. I switched firewire cables on the hard drive to a 800/400 so that the hard drive was now operating as a 400 and I did not have any more interface drop outs.
Even though the iMac has 2 firewire ports, they connect to a single cable to the i/o inside the Mac. If I try recording to an external hard drive, that is 24 tracks going into the Mac, back out to the hard drive, back in to the Mac and then back out to the interfaces and on to the monitor speakers. That is a lot to ask of a firewire connection.
So, I record to the internal drive and use the external for backing up and saving the projects.

Best Network Settings for mostly wireless, sometimes wired?

Folks:
My household --4 desktops Macs, 2 MacBooks, all running 10.4.x or 10.5.x-- lives by using DSL via a Netopia router controlling a LAN, with Cat 5 strung to six desks. No problem there, everything works. Note: for historical reasons --because, mostly, I forget what they were-- all desktops have static IP addresses.
But sometimes one of us wants to work in the house on a MacBook where there is no Cat 5 strung, that is, wirelessly. It's simple enough to set up a wireless server on one of the Airport-equipped desktops and make certain it stays awake.
That works, too, as long as each MacBook is configured with separate Network Preference "Locations" -- one for "Wired" and one for "Wireless", and the wireless configuration is IPv4 using DHCP with IPv6 disabled. Specifically, this requires the user to switch the Location when he/she connects or disconnects a Cat 5 cable.
My questions:
1. Is there a way of configuring the MacBooks so they will work without the requirement switching the Location when removing or connecting a LAN cable?
2. Can this configuration also accommodate what is needed for typical hotspots out there in "the outside world", as in coffee-shops, etc, again without switching the Network Preference Location?
3. Bonus Questions: Would this problem be easier if I modified the wired system configuration to use DHCP instead of fixed IPs? By the way, the Netopia Router will assign addresses in the 192.168.0 to 192.168.15 range, no others.
4. Double Bonus Questions: What are the responses to the above questions, if instead of serving the wireless from one of the desktops, we added a wired/wireless router, say, a D-LINK WBR1310B1 to the LAN? Yes, it's true, we have already tried that. (Our teenager bought and installed it without my...help.) It worked for a while, something unknown changed, and now wiring up the D-LINK brings down the entire LAN. In other words, what are the "issues" of running wired AND wirelessly, and using Airport remotes with a foreign (non-Apple) wireless router?
TIA,
Henry

1. Is there a way of configuring the MacBooks so they will work without the requirement switching the Location when removing or connecting a LAN cable?
Yes, but it's a little freaky (in other words, using the Location menu is the better solution).
To do what you want you need to setup the wireless network on the desktop using a different subnet (e.g. 10.1.x.x) and enable internet sharing (System Preferences -> Sharing).
Then connect the MacBook to the wireless network and make sure it's set for DHCP (the desktop Mac will act as a DHCP server for the wireless network).
Now the kicker is to use MacBook's System Preferences -> Network -> Set Service Order to make sure the ethernet interface is above the AirPort interface. Now the MacBook will use the ethernet interface if it's there and fall back to the AirPort if the ethernet is down.
2. Can this configuration also accommodate what is needed for typical hotspots out there in "the outside world", as in coffee-shops, etc, again without switching the Network Preference Location?
Yes. Most hot-spots will require the use of DHCP on the client, which is the same as how it's set above.
3. Bonus Questions: Would this problem be easier if I modified the wired system configuration to use DHCP instead of fixed IPs?
Yes, but not significantly enough to worry about.
What are the responses to the above questions, if instead of serving the wireless from one of the desktops, we added a wired/wireless router, say, a D-LINK WBR1310B1 to the LAN?
The setup on the client would be the same - the main point is in setting the interface preferences so that the wired ethernet has precedence.
However, a dedicated base station will offer other advantages such as WPA encryption (the Mac-based base station only offers the weaker WEP), and no requirement to leave the desktop Mac running.
From a 'which base station' standpoint, the Apple base stations would be easier to run in an all-Mac environment, but most of the major brands now use web-based interfaces which make them reasonably easy to manage from a Mac. The issue with your D-Link is almost certainly one of misconfiguration rather than incompatibility, but without knowing how it was setup it's hard to advise further.

Assigning multiple interfaces for Oracle API Gateway (OAG)

We are deploying Oracle API Gateway to throttle our incoming API requests. We would like to keep the incoming external API requests separate from the internal configuration management so that they go through different interfaces when accessing the OAG server. This is mainly for security reasons so that the external people won’t have access to the interface used by internal operations team to manage OAG. Based on your experience, is there any standard best practice to accomplish this? We were thinking to perhaps use two of the server’s network interfaces with different IPs, one for the incoming API requests and the other for the internal admin management of OAG. But not sure if this is the best way to do what we need. We are aware of OAG's capability to support two separate ports to handle this situation, but would like a more secure set-up that could completely eliminate external access to the OAG management done by the IT team.
Would appreciate any thoughts on best practices used regarding multiple interfaces for OAG set-up. Thank you. Oracle Marketing Cloud.

You are on the right track.
Here is how you can achieve this:
You can use multiple network interfaces on the UNIX machine and setup networking/routing in such a way that all external traffic comes on on one card and is routed internally via a different card.
Segregate difference types of services (i.e to be used by external clients vs internal apps) into difference different "Service Groups". Have each of these service groups listen on different port + NIC card (under Listeners, you can define a port to list to list on a specific network address and port instead of *).
Setup additional protection for services that will be accessed by external clients. Use "Threatening Content " filter to protect your services.
Setup 2 way SSL for the interface that will be called by external clients. Setup a DN based authorization check if you want to have both authentication and authorization.
Hope this helps.
-Thanks,

Looking for a wireless router / accespoint with radio time restriction

I am looking for a wireless router / accespoint with a radio time restriction but didn't find any information about this option. Are there any routers with the option to turn off the wireless signal between a specific time?
The router will be used at a small office .
I hope you can tell me more.
Cheers
Michel

Well there is No router which linksys/cisco manufacture that can stop the wireless signals to be broadcast for a specific time..
However what you can do is you can get into the setup interface of the router and disable the SSID broadcast and that will stop the router to broadcast the wireless signals...and whenever you need to enable it you can just go back into the setup page of the router and enable the broadcast again.

OTV Internal Interface Configuration

Hi
I am trying to implement OTV between 2 sites. I am slightly confused about the config for the join interface and site VLAN. Attached is the basic setup on one of the sites, I am using ASR 1002X routers to perform the OTV functions.
There seem to be limited sources for the ASR OTV configs, but on source states the internal interface on the ASR router should be configured as follows for each vlan
no ip address
service instance 10 ethernet
  encapsulation dot1q 10
  bridge-domain 10
service instance 20 ethernet
  encapsulation dot1q 20
  bridge-domain 20
service instance 30 ethernet
  encapsulation dot1q 30
  bridge-domain 30
I guess on the internal switch it will just be a trunk port allowing the above VLANs?
Thanks

Thanks Minh,
So it is possible to have switchports configured as routed, fabricpath and trunk/access in a fabricpath configuration? Do i need to add any spanning-tree pseudo or priority configuration?
Sample configs:
#ASR
interface GigabitEthernet0/0/1
no ip address
service instance 1 ethernet
  encapsulation dot1q 1
  bridge-domain 1
service instance 2 ethernet
  encapsulation dot1q 2
  bridge-domain 2
service instance 3 ethernet
  encapsulation dot1q 3
  bridge-domain 3
#Nexus 56xx
interface e1/5
switchport mode trunk
switchport trunk allow vlan 1,2,3
