When using VMWare to do work on my virtual machines, I came across an annoying bug where all my SSH connections failed:
$ ssh email@example.com packet_write_wait: Connection to 22.214.171.124 port 22: Broken pipe
$ git clone firstname.lastname@example.org:bycEEE/bycEEE.github.io.git Cloning into 'bycEEE.github.io'... packet_write_wait: Connection to 126.96.36.199 port 22: Broken pipe fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
Finally found a discussion on this issue here
~/.ssh/config fixed my issues:
Host * ServerAliveInterval 600 TCPKeepAlive yes IPQoS=throughput
