ControlPath can be too long #31

neutrinonerd3333 commented 4 years ago

I've was using forward to run Jupyter notebooks on Sherlock, using the default ssh config in hosts/sherlock_ssh.sh, and recently encountered an SSH Error: ControlPath too long.

I discovered that it was because the default ssh config includes the full hostname in the ControlPath for the Sherlock connection. I was at SLAC, and the hostname my machine was assigned was surprisingly long. I fixed this by replacing the ControlPath name %l%r@%h:%p with %C, which gives a hash of %l%h%p%r (see ssh_config manpage).

(So… pr maybe?)
