ssh broken pipe

This is a common problem that can be caused by several factors, e.g. SSH config, network instability, client power-saving settings. Possible solutions are:

  • Add the following settings to ~/.ssh/config on the client that keeps losing the connection:



ForwardX11Timeout 596h
  • Use a tool such as screen or tmux which allows you to detach from and re-attach to a terminal session on the target server.
  • (MacOS only) Start your ssh session using caffeinate which will prevent your Mac from sleeping during the session, e.g: 
caffeinate -i /usr/bin/ssh
  • (MacOS only) Check the energy saver settings and set:
    • On: Prevent computer from sleeping automatically when the display is off
    • Off: Put harddisks to sleep when possible
