Bug ID: 2255
Summary: tunneling with -W does not report non 0 exit codes on
failure even with ExitOnForwardFailure=yes
Product: Portable OpenSSH
Version: 6.6p1
Hardware: amd64
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: ssh
Assignee: [email protected]
Reporter: [email protected]
Currently it looks like there is no way to trap unsuccessful port
forwards using ssh -W
Example:
$ ssh -o ExitOnForwardFailure=yes -W localhost:1590 remotehost
$ echo $?
0
1590 is not listening on remotehost and debug output shows:
channel 0: open failed: connect failed: Connection refused
But ssh exits with 0.
Changing ExitOnForwardFailure has no effect.
It should exit(1) like nc does
