Querry about contrack

[Dhirendra Pal Singh]

Hi All,

Is it possible to find

A) number of packets recived and send,

B) no of connections existing

on the basis of port no.  ???

Does contrack keeps a track of it.. or something else...
I think somwehere in /proc contrack keeps a list of the active 
connections.. but I need the info to analyse it in my piece of c code.

Any ideas how can I do that..

Thanks in Advance
Dp

   A simple "cat /proc/net/ip_conntrack | wc -l" will tell you how many
connections are currently being tracked.  This does include possibly
failed connections as well though ([UNREPLIED]), so some use of grep or
perl on the output is probably a good idea.

   As for the packets received/sent, you'd have to either set up
accounting targets per port (ick), or simply LOG every such packet and
then count the matching lines in the syslog file(s).  Ugh.

  Maybe ULOG or similar can be of help with this.
