How to kill a tcp connection

[Daniel Ubeda]

Hi,

I need to kill several tcp connections in linux RH 8 and 9.
Are there any command to do this ?

thanks

If the process id's or names are identifyable, you can use the utility I'm attaching to kill the processes.

Its a hpux script and will require adaptation.

You should also consider setting up iptables to block certain ports if you want to stop these tcp connections permanently.

I can't identify the process because is a broken connection, and I can view it with netstat -na

if you add a -p to your netstat command:

netstat -anp the running command may show up in the last column

what state is the port in?

if it is in fin_wait2 then you may have to do something drastic. I usually restart my network device to clear these

service network restart

will restart the network for your verison of redhat.
