I always could connect to my companys Microsoft Lync network which is based on SIP. There is an addon for Pidgin called pidgin-sipe. Everything worked fine unless the company changed something weird. Now I always get a Read Error when I want to connect.

The debug output shows the following:

Isn't it possible anymore to connect or is this an error of pidgin-sipe?

    You might want to give wync a try instead

~$ export NSS_SSL_CBC_RANDOM_IV=0

~$ pidgin

Seems to do the trick, not sure exactly what it does. I need to read up on it.

Here is the bug traq for the issue: https://bugs.launchpad.net/ubuntu/+source/pidgin/+bug/950790

  • Thanks, this is great. I just created a custom script to start pidgin with this setting. Would be nice to hear from you if you know what this option does exactly.

  • Thanks! it seems to solve the "Read error", but I still getting auth error. Did you have to configure something special? Aug 1, 2012 at 9:18

    Note: You can avoid having to use a script by condensing this into one command: NSS_SSL_CBC_RANDOM_IV=0 pidgin Aug 23, 2012 at 17:44
  • Perfect! Works for Windows as well! (Add that into user environment) Apr 4, 2013 at 14:12
  • Doesn't work for me.

Other answers are old ways.

There is now a config file you should edit.

sudo -e /etc/default/pidgin-sipe

Uncomment the line that reads,

# export NSS_SSL_CBC_RANDOM_IV=0

(remove the '#' write the file and restart pidgin)

just add:

NSS_SSL_CBC_RANDOM_IV=0

to /etc/environment

and it will persist without you needing a non-standard startup script for pidgin.

To get it working with how you normally start applications in Ubuntu, and not getting into the way of other programs, you can copy the pidgin's launcher to ~/.local/share/applications/ directory by issuing the following commands:

mkdir -p ~/.local/share/applications
cp /usr/share/applications/pidgin.desktop ~/.local/share/applications

Then edit the file with your favorite editor, e.g.

nano ~/.local/share/applications/pidgin.desktop

Replace the line Exec=/usr/bin/pidgin with the following:

Exec=env NSS_SSL_CBC_RANDOM_IV=0 /usr/bin/pidgin

  • While this method works. It's way complex and doesn't catch invocations of pidgin from other routes. Try this instead Apr 8, 2015 at 23:23
