Ive been told to use the 'conntrack' utility ( for some purpose.

now as in the description writen:

  conntrack -L
      Dump the connection tracking table in /proc/net/ip_conntrack format

so i found the log file in /proc/net/ip_conntrack and it updates at realtime on every ip conntrack, but when i type 'conntrack' i get not found. its a d-link router with Linux version 2.4.20

how can i find that file to use it if they changed the name or its hidden somewhere

Which custom firmware are you using? – Hyppy May 27 '11 at 15:03
its not custom its a pocket router that came build in with busybox(1.00) router firmware is 1.02 - d-link Dir-457U – PyThoN May 27 '11 at 15:05
I have the open GPL right in front of me but i still cant point on the file location – PyThoN May 27 '11 at 15:08
What is a GPL, besides the GNU Public License? – Hyppy May 27 '11 at 15:12
Its the router open source at least thats how d-ink calls it, i can modify compile and the install custom firmware – PyThoN May 27 '11 at 15:23

conntrack is an utility to see and modify the conntrack tables - but they are unrelated as far as dependencies go. The fact that you have conntrack tables (that's what you're seeing in /proc) doesn't imply you must have this utility: the tables are part of Linux itself, you could say, but the utility is just that - an utility - and indeed it's more likely not to be present as it isn't in most default installs, and I would not expect it to be present in a router Linux distribution.

See your distribution docs to find out how to install utilities, but try /usr/sbin/conntrack just in case it's installed to /usr/sbin and you haven't got the standard root $PATH set.

As a last resort look for it in the whole filesystem (you could use locate for faster searching, but I'm guessing your router distro doesn't have it installed):

find / -name 'conntrack'

i guess you are right, not exist in /usr/sbin or /usr/bin and also i do not have find or locate installed there :( thank you. – PyThoN May 27 '11 at 15:25
i just hope they didnt just changed it name like i saw on other files – PyThoN May 27 '11 at 15:26
