Running OpenSSH 3.9p1 on AIX 5.1

Subject: Running OpenSSH 3.9p1 on AIX 5.1

Hi,

Just came across a couple of situations after transitioning away from
ssh.com to OpenSSH (now that gssapi+mic is supported)  One I will send
in another email regarding another OS, but we have a AIX 5.1 box where
3.9p1 has compiled and sshd is running, however, no clients can connect
to that host. ("ssh_exchange_identification: read: Connection reset by
peer")  Debug logs below:

-=-
# /tmp/openssh-3.9p1/sshd -ddd
debug3: Seeding PRNG from /usr/libexec/ssh-rand-helper
debug2: load_server_config: filename /etc/sshd_config
debug2: load_server_config: done config len = 191
debug2: parse_server_config: config /etc/sshd_config len 191
debug1: sshd version OpenSSH_3.9p1
debug3: Not a RSA1 key file /etc/ssh_host_rsa_key.
debug1: read PEM private key done: type RSA
debug1: private host key: #0 type 1 RSA
debug3: Not a RSA1 key file /etc/ssh_host_dsa_key.
debug1: read PEM private key done: type DSA
debug1: private host key: #1 type 2 DSA
debug1: rexec_argv[0]='/tmp/openssh-3.9p1/sshd'
debug1: rexec_argv[1]='-ddd'
debug2: fd 3 setting O_NONBLOCK
debug1: Bind to port 22 on 0.0.0.0.
Server listening on 0.0.0.0 port 22.

% openssh -vvv catbert
OpenSSH_3.9p1, OpenSSL 0.9.7d 17 Mar 2004
debug1: Reading configuration data /etc/ssh/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to catbert [10.0.2.13] port 22.
debug1: Connection established.
debug1: identity file /udir/plosher/.ssh/identity type -1
debug1: identity file /udir/plosher/.ssh/id_rsa type -1
debug1: identity file /udir/plosher/.ssh/id_dsa type -1
ssh_exchange_identification: read: Connection reset by peer

There is no activity on the server end while the client is trying to
connect.  Any ideas what could be causing this?
