SSH session timeout

Hi Guys,

 

I need help please on how to increase timeout for SSH session, we have a Virtual server with service port of 22 and pool member with health monitor of tcp. If we keep the ssh session idle (using putty & user login) for more than 5 mins it automatically get disconnected.

 

regards Caswell

    Our Linux team made these changes on their side but still the problem persist.

     

    Host * ServerAliveInterval 120 ServerAliveCountMax 30 ConnectTimeout 30

    Please configure TCP profile with an idle timeout as per your requirement and then assign to the virtual server on F5.

    Hi Caswell,

    This is working as per your current design. If you'd like to have increase the idle session time, you are required to have a custom profile mapped to your existing Virtual Server.

    Refer the article K7606: Overview of BIG-IP idle session time-outs

    TCP profile - The default idle timeout is 300 seconds. Which is 5mins.

    Do not map this tcp profile, rather create a new custom tcp profile and modify the timeout value to your needs. And then map the custom profile to your VS.
