Open SSH Connections

I have 2 machines running AIX and OpenSSH. I am trying to connect from one to the otherwithout success. The details are as follows:
Server1 AIX v 5300-07-01-0748 OpenSSH version 4.5p1 openSSL version 0.9.8d
Server2 AIX v 5300-00                OpenSSH version 4.3p2 openSSL version 0.9.7g

ssh server1 to server2 hangs - debug output is:

OpenSSH_4.5p1, OpenSSL 0.9.8d 28 Sep 2006
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Failed dlopen: /usr/krb5/lib/libkrb5.a(libkrb5.a.so):   0509-022 Cannot load module /usr/krb5/lib/libkrb5.a(libkrb5.a.so).
        0509-026 System error: A file or directory in the path name does not exist.

debug1: Error loading Kerberos, disabling Kerberos auth.
debug1: Connecting to server2  [0.0.0.0] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
debug1: old_gid:0       pw->pw_gid:0    pw->pw_uid:0
debug1: identity file /.ssh/identity type -1
debug1: identity file /.ssh/id_rsa type 1
debug1: identity file /.ssh/id_dsa type 2

We expect the Kerberos error. The session hangs at this point.

Both machines can ping each other and ssh from Server2 to Server 1 works perfectly. I suspect that it is a networking problem but what I would need to find is the IP address which Server1 is using to connect to Server2

IP details of the two servers are:

Server1 -
