Hi All, it's the first time for me on this forum.

I'd like to have some hits from you about a problemi on ssh connection.

I have two servers with RedHat 5.4 installed and I have an application that looks like a cluster handler (as veritas, heartbeat, suncluster, redhatcluster and so on). This Application is not graphic and when I started it makes an "attach" to the bash shell.

My problem is the following:I connect through Putty client and after some minutes the ssh connection goes in INACTIVE mode. At this point I lost the bash shell with the prompt of application. It is not possible "detach" the application from the shell so I did the following instruction to avoid the inactive state of ssh connection:

I modified sshd_config file only

TCPKeepAlive yes
ClientAliveInterval 300

and then
/etc/init.d/sshd restart

Unfortunately it doesn't work. Is there any other solution to keep "ACTIVE" the ssh connection?

Thank you very much

just set a keepalive on putty, make it check every 10 seconds in the gui and you should be ok, assuming that you do actually not use the connection for a period of time, and these interruptions aren't in the middle of being used.

Thank you! I already tried to set keep alive on client and it works properly but for my scope I should keep alive the ssh session "for ever" unless I terminate it. Therefore I have to avoid the "crash" of ssh connection and shell.

Do you have any other suggestions?

Thank you for you availability

well that IS what a keepalive is for...? you can't stop something """"crashing""""""" though.

Ok I knew that, I meant that I cannot modify the keep alive by the remote client. I need to find a solution by the server!!!

Do you know any solution?

Thank you in advance!
