    Hi

    I am facing a very strange problem with my AIX box, 5.3 TL7.
    When connecting to the server remotly using telnet or ssh, in hunder times, only 3 or 4 times it gets successful login else I get connection closed by remote host.
    But at the same time, I get successful login through a perticular ID. But thats also from one machine and not from other and that also stops sometimes and starts login from other.
    I have tried reinstalling openssl, ssh and rebooted the machine.
    Even that user is not able to login from same server to 127.0.0.1 IP or its public IP.

    sshd_config is same in all servers. no paramenters are also not altered.

    one important thing here is that, through public key, login is perfect, through expect script also, login is happening.

    No problem in ssh debug output.

    Any suggestion?
