Hi All,

I'm looking for a Linux tool which can just establish a TCP session and leave at it there w/o sending a FIN /RST.
I tried tools like iperf etc., which sends out a FIN as well once the connection is established.
kindly let me know if there are any tools that are avaiable?
Thanks

You can simply use telnet. There are also other ways you could programmatically do this. Unfortunately there may other things between you and the remote end that may terminate the session. Many proxy servers and firewalls close inactive sessions without traffic over them. A common timeout is two minutes without traffic. This is done to conserve resources. Each connection that is kept open consumes resources.
