SSH connection freezes


My ssh connected terminal freezes after sometime (after being inactive for few minutes), I’ve changed the /etc/ssh/sshd_config to

TCPKeepAlive yes ClientAliveInterval 30 ClientAliveCountMax 99999

and restarted the ssh daemon service,

still it’s not working.

(I’m using Ubuntu 20.04 (LTS) x64)

Hi @thenishantgiri,

You’ll need to change the SSH settings on your local machine as well. To get your configuration working, make these configuration changes on the client:

Host *
ServerAliveInterval 100

**ServerAliveInterval **The client will send a null packet to the server every 100 seconds to keep the connection alive
