Hello

We have AIX 5.2 (5200-09-04) with openssh-4.3 (sum says: 17387 4513 openssh-4.3p2-r2_52.tar.Z).

If I enable authentication agent forwarding from remote host, ie.

ssh -A broken_52_ssh_host

connection will terminate with error:
Received disconnect from xxx.xxx.xxx: 2: bind: Invalid argument

When disabling authentication agent, ie.
ssh -a broken_52_ssh_host

connection works.

SSH configuration is from new package (removed the old one).

bash-2.05b# ls -la /usr/bin/ssh*
-r-xr-xr-x 1 root system 1260276 Apr 06 06:43 /usr/bin/ssh
-r-xr-xr-x 1 root system 398572 Apr 06 06:43 /usr/bin/ssh-add
-r-xr-xr-x 1 root system 290292 Apr 06 06:43 /usr/bin/ssh-agent
-r-xr-xr-x 1 root system 486900 Apr 06 06:43 /usr/bin/ssh-keygen
-r-xr-xr-x 1 root system 730982 Apr 06 06:43 /usr/bin/ssh-keyscan
bash-2.05b# ls -la /usr/sbin/ssh*
-rws--x--x 1 root system 727907 Apr 06 06:43 /usr/sbin/ssh-keysign
-r-xr-xr-x 1 root system 111138 Apr 06 06:44 /usr/sbin/ssh-rand-help
er
-r-xr-xr-x 1 root system 1758663 Apr 06 06:44 /usr/sbin/sshd

Please, help.

    hello - you'll get the same error when starting ssh-agent, eg. ssh-agent -s|-c

    Yes, it seems broken:
    OpenSSH_4.3p2, OpenSSL 0.9.7d 17 Mar 2004
    on AIX
    oslevel -r: 5200-09

    When trying to ssh -A on that box:
    Received disconnect from 138.nnn.nnn.nn: 2: bind: A system call received a parameter that is not valid.

    the problem has already peeked and forwarded to maintainer: bind fails due to compilation with aix5.3 includes, hence
    sockaddr for bind has wrong size!!
