           Summary: unexpected warning for mux control commands when stdin
                    is not connected to a tty
           Product: Portable OpenSSH
           Version: 5.4p1
          Platform: All
        OS/Version: OpenBSD
            Status: NEW
          Severity: minor
          Priority: P2
         Component: ssh
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: sfandino at yahoo.com


Example:

$ ssh -O check -S /foo/bar -- host </dev/null
Pseudo-terminal will not be allocated because stdin is not a terminal.

Is there any reason to force tty allocation when a mux command is
given?

As a workaround -T can be used:
$ ssh -T -O check -S /foo/bar -- host </dev/null
