I have two different servers, one has ubuntu 12.10, the other has ubuntu 14.04 LTS. I need to SSH files to a 3rd remote server. The 14.04 LTS server throws an error when attempting to SSH.
This is the log of 14.04 in verbose mode:

Because of the write | broken pipe
error, I added the following options to /etc/ssh/ssh_config
:
TCPKeepAlive yes
ServerAliveInterval 120
However error still persists. Any assistance would be greatly appreciated.
Also, this might be related to using SSH with passphrase instead of a standard public key.
ssh
works, and 14.04 LTS wheressh
does not work. Not sure how to diagnose the underlying problem from this point. I'll edit the question to make it more accurate.
