SSH Broken Pipe Issue

Problem:

My laptop struggles at keeping an SSH connection alive with its default settings. See my pipe break below.

ubuntu@ip-10-106-2-194:~$ client_loop: send disconnect: Broken pipe

This is very annoying, especially if you are attempting something that requires long intervals of inactivity between commands.

Solution:

Glancing through the SSH documentation, I found two settings that looked to be of importance.

• ServerAliveInterval
• ClientAliveInterval

They appear to be intervals that can be set on the server or client that send a keep alive request through the connection.

By setting the ServerAliveInterval on my local machine I found my SSH connections to persist without intervention.

File: ~/.ssh/config:

ServerAliveInterval 120

I also went ahead and put the ClientAliveInterval setting into my personal AWS boxes.

File: /etc/ssh/sshd_config

ClientAliveInterval 120

Enjoy!
