Very Computer

Hello !
I'm searching for a method to find out which process occupies a given
tcp or udp
port.

For example :

searching for the udp port 162 you will get in most cases :

snmpd (or its pid)

Is there any chance to do this ? I read the man page about the /proc
filesystem
but found nothing to start with.

Perhaps in a newer kernel ( I'm using 2.0.18 ) ?

Answers also per mail to me, please !

Thanks in advance

Thomas Gebert

The list of "known" ports on your system will be listed in /etc/services.

To reply via mail, please remove the obvious from the email address.

I know this. But if some crazy process occupies for example port 162 with
protocoludp I want to know what is the pid or name of this process.

/etc/services only gives a name for a port number so that a program can get
a
specific port by name.

For example :
netstat gives the service names if it can get it from /etc/services.

So this is not enough for me, but thanks.

Try:

        $ lsof -i:162

Lsof is available (including source code) at:

        ftp://vic.cc.purdue.edu/pub/tools/unix/lsof

and (perhaps closer to you) at these .de mirrors:

        ftp://ftp.fu-berlin.de/pub/unix/tools/lsof
        ftp://ftp.uni-mainz.de/pub/misc/lsof

Revision 4.35 is the latest.

Caveat: the one I have doesn't seem to work on 2.1.x kernels...
