Question:
The connection keeps dropping after 5 minutes of inactivity:
- I connect to my server via SSH
- I go to Google to look for a command, for example, to find a file
- go back and the
git bashwindow is not responding - restarting it
- re-enter password …
This is extremely annoying! Why and what to do about it?
Answer:
Usually the sshd server will close inactive connections. I often came across that routers also terminate connections that are "silent" for some time.
You can persuade the client to send an I-live signal all the time. In ~/.ssh/config add (in seconds):
Host *
ServerAliveInterval 120
If the file still does not exist, you need to create and in order to avoid an error
Bad owner or permissions on ~ / .ssh / config
remember to change the write permissions (in some versions also read):
chmod go-rw ~/.ssh/config
# или
chmod 600 ~/.ssh/config
Without configuration, you can try: ssh -o ServerAliveInterval=120 iam@my.home.ru

In PuTTY, this is set in the menu – Connection> Seconds between keepalives (0 to turn off).
