One of my server computers shows a "broken pipe" message while I'm using SSH after 10 minutes even though I execute simulation program programmed with python3.5.

I tried

  1. Editing sshd_config and ssh_config files
  2. Ignoring power-save mode
  3. Re-installing Ubuntu 16.04
  4. Using tmux for the simulation.

In addition, after the disconnection between the server and local client, I tried tmux attach command but it didn't work.

The most weird thing is only the one server shows this symptom. Other server works well without any broken pipe message.

What should I do?

Depending on the servers settings, idle connections may be dropped.

To prevent this from the client side, use ssh option ServerAliveInterval.

Use this in your ~/.ssh/config

Host xyz
    ServerAliveInterval 120

or using command line option ssh -o ServerAliveInterval=120 ...

Alternatively, you can change the setting from the server side in ssdh_config:

ClientAliveInterval ...
