Server Bug Fix: Configuration of a Cisco IP Phone 7916 and 7975g

Original Source Link

Hi everyone,

I would appreciate some help configuring my Cisco IP Phone 7975.
In fact the phone works well with the SIP firmware (version SIP75.8-4-1ES2) and an Asterisk Server. Now I would like to connect a Cisco IP Phone 7916 Expansion Module to it. The problem is during my search on the web I have only found explanations to configure the expansion with a Cisco Unified Call Manager but not with Asterisk.

For information, the IP Phone gets its configuration file from a tftp server and the file follows the SEP.cnf.xml format.

So if someone here have already done this task before, can he pleases explain me.

Thanks in advance for your help.

Alex

I haven’t had very much success with these phones and Asterisk in SIP mode. However, they work well using SCCP. Take a look at this SCCP module for Asterisk.

I just configured a 7016 module successfully. You need the firmware for the add-on module and then in the SEP.cnf.xml file, you add this after the tag:

<addOnModules>
<addOnModule idx="1">
<loadInformation>B016-1-0-4-2"</loadInformation>
</addOnModule>
</addOnModules>

Then, in the <sipLines> node, you add entries such as this one for the keys you want to configure:

<line button="9">
<featureID>21</featureID>
<featureLabel>Joe Bloggs</featureLabel>
<speedDialNumber>4000</speedDialNumber>
<featureOptionMask>1</featureOptionMask>
</line>

Then, update your device with this configuration file and firmware using the TFTP process and it should work out fine.

Hope this works for you!

Server Bug Fix: Cisco Aironet 1200 mode button disabled

Original Source Link

I received a free Cisco Aironet 1200 and tried to restore it using the mode button but it was disabled and no one knows the password for the WAP’s interface. Any ideas how I could get it reset?

You’ll probably need to attach a serial cable to the console port. Getting console on cisco devices can be a real pain. You basically want the baby-blue RJ45-DB9 cables that comes with real routers.

Try following the directions in the link below for the Aironet 350 (which lacks a mode button):

http://www.cisco.com/c/en/us/support/docs/wireless/aironet-1200-series/9215-pwrec-2.html#connecting_ap

Briefly, you want to interrupt the boot process with ESC, then flash_init to load the flash memory, and then rename the config.txt to something else, and reset. This should restore factory defaults.

To return all access point settings to the factory defaults including password you need to use the MODE button.

Disconnect the power and press and hold the MODE button while you reconnect power to the access point. You need to hold the MODE button until the ethernet LED turns amber (approximately 2 to 3 seconds), then release the button.

Then you can connect with cisco/cisco via serial console or web gui.

Server Bug Fix: zabbix import trigger template

Original Source Link

i am importing a zabbix template, the items load successfully

snippet of the xml template:

      <triggers>
        <trigger>
          <description>PING response on Vlan1</description>
          <type>1</type>
          <expression>{11.11.11.11:icmpping['11.11.11.11'].last(0)}=0</expression>
          <status>0</status>
          <priority>0</priority>
          <comments>Interface: Vlan1 is down</comments>
        </trigger>
      </triggers>
    </host>
  </hosts>
</zabbix_export>

but when it reaches the trigger section while importing it gives this error:

Added new item Template_Test_Router_Ping:icmpping[11.11.11.11,3,25,68,500]
[ CTrigger::create ] No permissions !

any idea which permissions its referring to?

Looks like parent template didn’t exist, could be various reason such as linked with other template.

why dont you try Importing template element only and then import everything doing same for the host, First imported hosts and then imported everything else. (Importing the base “Elements” only in the first import then, Importing the everything else the second import.)

Hope this helps

Server Bug Fix: Replace a Cisco VPN IPSec concentrator with an Ubuntu-box

Original Source Link

Is it possible to replace a Cisco VPN IPSec concentrator with Ubuntu and for instance Strongswan?

1) Do Strongswan implement the same protocolls that Cisco uses?

2) Can we retrieve keys from the Cisco concentrator and import them to the Ubuntu-box, if not can we generate new keys that suits equipment at sites?

3) Are there any performance concerns to think of?

I’m sure you can find examples of remote-access VPN and site-to-site VPN configuration for Strongswan listed here helpful.

Server Bug Fix: Putty blank when connected to Cisco Catalyst 3500

Original Source Link

I’m using the normal blue RJ45 to DB9 cable plugged into my Cisco Catalyst 3500 series XL switch. That cable is connected to a serial-to-usb adapter that I got from Monoprice, and that is plugged into my computer (running Windows 7).

When I go into the device manager, I see that it uses COM5, so I’m trying to connect to that with putty. However, when I click “open” it just opens a black screen in putty. When I hit enter, nothing happens. I’ve tried looking around, but I can’t figure out how to get into the switch.
So far, I’ve tried updating the driver. Windows says it’s update to date. I’ve tried matching the settings I see in the device manager to the settings in putty:

Bits per second: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

I’ve also tried changing some of those settings to see if anything would happen, but it’s the same result every time. I’ve changed them back to as they are above.

It seems that my computer recognizes the device and the connection because of what it shows in the device manager, but it just seems to be refusing to communicate. If I try to make the connection in putty, and then unplug the cable from my computer I get an error message: “Error reading from serial device”. If I unplug from the switch, or unplug the adapter, I get no error. I’ve also tried using a second switch (same model), and I get the same results.

Valid speeds (other than 9600bps) include 1200, 2400, and 4800 bps. On some platforms 19200, 38400, 57600 and 115200 bps are supported. Try these if you fail to connect. I’ve had this issue in the past and using a faster speed (115200 in my case) solved the problem.

Baud rate is the issue here, try and use all the baud rate above one at a time to see which one go with the baud rate configured for the switch.

I had the same issue until I went into device manager and installed the driver for the USB to Serial cable. Then no problem.

Ubuntu HowTo: Wine: using webcam with Cisco Jabber Video client

Original Source Link

I’m trying to use Cisco Jabber Video client (https://www.ciscojabbervideo.com/home) with Wine but I’m unable to get the webcam to work.

Steps that I have completed this far:

  1. Register an account for Cisco Jabber Video (required to get the download link for the application).

  2. Install Cisco Jabber Video Client.

  3. Run Cisco Jabber Video Client. This part was problematic until I found out that this application expects to find a copy of ksuser.dll int the system. I located a copy of said DLL from the dlldump.com and put it in ~/.wine/drive_c/windows/system32 and everything else but video from webcam seems to work.

I’m able to successfully use the webcam without wine. The webcam already works with Skype, Cheese Webcam Viewer, guvcview, luvcview and Flash plugin (both Firefox and Google Chrome). Still the Cisco Jabber Video client running on wine claims that I have no USB webcam installed in the system.

I also tried to add devenum override and deleted HKEY_CURRENT_USER/Software/Microsoft/ActiveMovie with regedit as suggested by http://wiki.winehq.org/MSN_Messenger_webcam_support

Can you suggest anything else to get the camera to work? (The reason I even need this stuff is I would need to connect to Cisco TelePresence SX20 hardware on the remote site and it seems that Ekiga is not compatible with that. Ekiga is never able to establish a connection with that thing.)

Update:
I forgot to mention the hardware I’m using:

Bus 003 Device 064: ID 045e:075d Microsoft Corp. LifeCam Cinema

Software:

Ubuntu 12.04.4 LTS 64-bit (precise with all the updates)
Wine 1.7.18-0ubuntu1 from ubuntu-wine PPA

A large number of cameras have been tested with several versions of Cisco Jabber Video for TelePresence. While Jabber Video should work with all USB cameras, the cameras that the Jabber Video team are using on a regular basis and are guaranteed to perform well are:

Cisco TelePresence PrecisionHD USB Camera (recommended for business-quality HD video)
Apple iSight cameras
Cisco VT Camera III
Creative Live! Cam Socialize HD 1080
Lenovo Thinkpad cameras
Logitech HD Pro Webcam C910
Logitech HD Webcam C310
Logitech QuickCam Pro
Logitech QuickCam Pro 9000
Microsoft LifeCam Studio
Microsoft LifeCam HD-6000

Cameras that support HD 1080

Logitech HD Pro Webcam C910
Microsoft LifeCam Studio
Creative Live! Cam Socialize HD 1080
HP Webcam HD-4110

Server Bug Fix: ->% 192.168.2.0 overlaps with FastEthernet0 / 0

Original Source Link

enter image description here

I am working within the Cisco Packet Tracer platform. I made all the necessary configurations but when assigning an IP address to my router, I get the error message in title and I do not know how to fix it. Anyone have any ideas?

I’m doing my best to interpret that diagram, but I’m not exactly sure what the diagram is showing due to the labels being in inconsistent places. However:

It looks like on Router10 you have 192.168.2.1/30 assigned to Se0/0/0. That subnet consumes the IP addresses 192.168.2.0 - 192.168.2.3

You also looks like you have 192.168.2.1 in your diagram assigned to Fa0/0. No subnet is mentioned, but if I assume that’s a /24 then you’ve assigned 192.168.2.0 - 192.168.2.255 to Fa0/0 as well.

So the router is correct, you have an overlapping IP configuration on two distinct interfaces on the same device, which is an invalid configuration.

Change your 192.168.2.1/30 link between Router10 and Router8 (I think? Router name is obscured) to a different subnet.

Ubuntu HowTo: 19.10 – Wifi – Linksys AE2500-RM not recognized by system

Original Source Link

I see this has been asked before, but not for 19.10, and not for FIVE years.

Linksys AE2500-RM wi fi adapter not even popping up on my Wi Fi Settings when I plug it in.

In five years, has there been a better solution than XP drivers to make this work?

EDIT: lsusb output:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub 
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub 
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub 
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub  

EDIT 2: removed the devide from it’s USB port and plugged it into a different port, reran the command and got the following:

Bus 001 Device 008: ID 13b1:003a Linksys AE2500 802.11abgn Wireless Adapter [Broadcom BCM43236]

There is no known native Linux driver for your 13b1:003a device.

Drivers are typically developed either directly by or in conjuntion with the device chipset manufacturer, in this case, Broadcom. They have provided no driver for this device nor any of the very few other Broadcom USB devices.

The alternative used to be to use Windows XP driver files and the ndiswrapper mechanism. However, ndiswrapper is poorly supported and hasn’t worked properly on any recent Ubuntu version for many years.

The direct answer to your question, “In five years, has there been a better solution than XP drivers to make this work?” is that there is no solution at all, including ndiswrapper, to make this work.

I suggest that you purchase another fully supported USB wireless device.
