SSH Timeout in centos8 vm

[Diptendu Tan]

Hello There,

I have created a centos 8 vm in gcp and enabled password login.And connecting to the vm via putty. Now after very short time of inactivity, I am getting ssh timeout in putty.

So I have modified the ssh conf as bellow but ssh timeout has not increased. Can someone please help me increase the ssh timeout.

TCPKeepAlive no

#PermitUserEnvironment no

#Compression delayed

ClientAliveInterval 420

ClientAliveCountMax 360

BR,

Google cloud has a session timeout across the board of 10 minutes, so you need to use a keepalive. Try adding the argument --ssh-flag="-ServerAliveInterval=30" - any value less than 600 should do the trick there. 

For more information you can also see this link [1].
