Thanks all of your for reply. Here is the output of command:


root at li496-23:~# lsmod | grep -i sip

root at li496-23:~#

This command is giving blank output.

This is linnode server. So the zcat /proc/config.gz command reveals the 
kernel loaded modules.
You can see complete output at pastebin:

Thanks in advance

Vijay Th.
