SSH inactivity timeout

We connect to Cisco switches which have a 5 minute inactivity timeout setup. We've tried changing the Rebex Keep Alive to 30000 (which should send a keepalive every 30 seconds) but we still get disconnected every 5 minutes. We tried changing to the Putty plugin and changing the Keep Alive Interval to 30 seconds but that would also still disconnect us every 5 minutes. Any suggestions on how to stay connected to the SSH session even though the switches are set to disconnect inactive sessions after 5 minutes?


It depends on the plugin you use.


For Rebex, go to the plugin settings and enable Keep Alive there:

https://docs.royalapps.com/r2023/royalts/reference/connections/terminal-rebex.html#plugin-settings


For PuTTY you can configure it in the Advanced settings of the connection:

https://docs.royalapps.com/r2023/royalts/reference/connections/terminal-putty.html#keep-alive-interval-sec


Let me know if this helps.

The Royal TS client should be able to send a keep alive to the switch to keep it connected even though the exec-timeout is set to 5 minutes. Do you have a doc that shows how to setup Royal TS correctly to do this? I've tried a bunch of things and it doesn't appear like Royal TS is sending the keep alive.

Hi Mike,


I've heard of devices/appliances which do not honor specific ignore packets used for keep alive functionality. AFAIK there's nothing on the client side to "convince" those devices to keep the connection open. I think your question should be directed to Cisco, F5 and similar companies ;)
