Question

SSH connection freezes

Posted September 22, 2021 598 views
Ubuntu 20.04DigitalOcean Droplets

Hi,

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:

/etc/ssh/ssh_config

Host *
ServerAliveInterval 100

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