Problem Formulation<\/h2>\n

I just tried to run AutoGPT<\/a> on an EC2 instance using SSH from my local Windows machine. But here’s the annoying part: the connection always closes and AutoGPT can only work in small ~10 minute increments<\/strong>. When I return to my machine, I need to SSH into my instance and restart the program.<\/p>\n

\"\u2694\" Problem Formulation<\/strong>: Your SSH connection to a remote server works properly at your workplace, but it freezes after 10-15 minutes when connecting from home. You don’t receive any error messages, but you notice zombie login users that need to be killed manually.<\/p>\n

Quick and Easy Solution (Client-Side)<\/h2>\n

To prevent an SSH connection from closing when the client goes silent, you can configure the client to send a keep-alive signal to the server periodically. <\/p>\n

Create a configuration file in your home directory at $HOME\/.ssh\/config<\/code>, and set its permissions to 600<\/code> using chmod 600 ~\/.ssh\/config<\/code><\/code> after file creation. To send a keep-alive signal every 240 seconds, for example, add the following lines to the configuration file:<\/p>\n

Host * ServerAliveInterval 240<\/code><\/pre>\n
You can get this done with the following two commands on Linux:<\/p>\n
printf '%s\\n' 'Host *' ' ServerAliveInterval 240' > ~\/.ssh\/config\nchmod 600 ~\/.ssh\/config<\/code><\/pre>\n
You can then check the file content using the command cat ~\/.ssh\/config<\/code> like so:<\/p>\n
\"\"<\/figure>\n
Alternative Solution: Server Side<\/h2>\n
In some cases, you have access to the server’s SSH settings. In that case, add an entry ClientAliveInterval 60<\/code> to the file \/etc\/ssh\/sshd_config<\/code>. I used the Vim editor in the terminal to accomplish this.<\/p>\n
