           Summary: Local Port Forwarding does not work in AIX 5.1 or AIX
                    5.2
           Product: Portable OpenSSH
           Version: 3.6.1p2
          Platform: PPC
        OS/Version: AIX
            Status: NEW

         Component: ssh
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: tech at rassin.com


Local port forwarding does not work with AIX 5.1 or AIX 5.2.  The same results
occur with both OpenSSH_3.4p1 and OpenSSH_3.6.1p2.  ssh segmentation faults 
when the connection is made to the local forwarded port.  Debug out put follows.

debug1: Connections to local port 24800 forwarded to remote address 
192.168.1.100:23
debug1: Local forwarding listening on 127.0.0.1 port 24800.
debug1: fd 4 setting O_NONBLOCK
debug2: fd 4 is O_NONBLOCK
debug1: channel 0: new [port listener]
debug1: Entering interactive session.
debug1: Connection to port 24800 forwarding to 192.168.1.100 port 23 requested.
debug1: fd 5 setting TCP_NODELAY
debug2: fd 5 is O_NONBLOCK
debug2: fd 5 is O_NONBLOCK
debug1: channel 1: new [direct-tcpip]
Memory fault(coredump)

What compiler are you using?  If it's the gcc-2.9whatever from the AIX
toolbox
CD, I suspect it's a compiler problem (I've seen it miscompile openssl
and I
suspect it of causing another couple of problems).

FWIW 3.6.1p2 works for me on 5.1 and 5.2 (compiled with gcc 3.3):

$ echo `uname` `oslevel`
AIX 5.2.0.0
$ ssh -v -L 2000:127.0.0.1:22 localhost
OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090702f

Compiled with gcc 3.3.1 and local port forwarding worked.

Original tests were done with openssh that was compiled with xlc "IBM
Visual
Age C/C++" and also with the openssh binaries distributed by IBM and 
bullfreeware.
