Package: pyhoca-cli
Version: 0.6.1.2

If the remote user does not exist, then pyhoca-cli exits with success (exit code 0). The calling script does not know then that the connection has failed.

For scripting purposes, it is important that errors are always signalled with a non-zero exit code.

Example:

$ pyhoca-cli  --server localhost  --username=does-not-exist

pyhoca-cli[97275] NOTICE: preparing requested X2Go session
pyhoca-cli[97275] (PyHocaCLI) NOTICE: preparing requested X2Go session

pyhoca-cli[97275] (PyHocaCLI) WARN: passwordless login for ,,does-not-exist'' failed [SSHException]
pyhoca-cli: error: No existing session

$ echo "Exit status code: $?"
Exit status code: 0

Thanks in advance,
