openssh bugs - Dec 2008 - [Bug 1543] New: ~C always opens command prompt on master session

https://bugzilla.mindrot.org/show_bug.cgi?id=1543

           Summary: ~C always opens command prompt on master session
           Product: Portable OpenSSH
           Version: 5.1p1
          Platform: All
               URL: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=50754
                    1
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: cjwatson at debian.org


In Debian bug #507541, Adrian Bridgett reported:

"I use multiplexed connections.  If in a slave SSH session I type
"~C"
to open an SSH command prompt, nothing appears to happen.  If I look at
the master SSH session though I see the "ssh>" prompt has appeared
there :-)  Not the end of the world, though it did confuse me for a
while (not least as it hangs the slave session until I've entered a
command on the master session)."

Created an attachment (id=1583)
 --> (http://bugzilla.mindrot.org/attachment.cgi?id=1583)
disable ~C for multiplexed slave connections

This patch takes the easy way out and just disables ~C for multiplex
slave connections. I'd like to fix it properly (i.e. make ~C work for
slaves too), but it is quite a bit of work -
clientloop.c:process_cmdline() would need a read_passphrase()
equivalent that worked with the stdio Buffers.

Perhaps a feature bug needs to be created to track Damien's comment
that really this needs reimplementing in the slave - after all when I
have four ssh sessions open I have _no_ idea which is the master more
often than not!
