    Thanks all for your help but the Pb doesn't seem to come from host name IP
    resolution.
    Indeed, the connection to server2 is very quick.
    The above step takes less than 1 sec !
    $ ssh -vv server2
    OpenSSH_3.8.1p1, OpenSSL 0.9.7d 17 Mar 2004
    debug2: ssh_connect: needpriv 0
    debug1: Connecting to server2 [IP@] port 22.
    debug1: Connection established.

    However, it's like the ssh client machine has trouble retrieving the ssh
    server version.
    debug1: identity file /home/user/.ssh/id_dsa type -1
    !!! Long time period (around 2mn) !!!
    debug1: Remote protocol version 1.99, remote software version OpenSSH_3.9p1

    I've checked the network, and nothing special to report either on this
    point.

    Any idea of what's going on ?
    Sabrina

    Hi,

    I compiled openssh exactly the same way on 2 identical HP-UX 11.11 servers
    (same patches level, same hardware config, etc.) and for an unknown reason
    the ssh connection to one (server1) is very quick but very slow to the
    other one (server2)...

    I traced the connection to both of them, and the second one get stuck at
    this level:
    debug1: identity file /home/user/.ssh/id_dsa type -1

    Note1: the user home dir is NFS mounted on both machines => same home dir
    from both servers.
    Note2: the server load is about the same on both machines.

    $ ssh -vv server2
    OpenSSH_3.8.1p1, OpenSSL 0.9.7d 17 Mar 2004
    debug2: ssh_connect: needpriv 0
    debug1: Connecting to ncegc201 [172.16.133.12] port 22.

    debug2: key_type_from_name: unknown key type '-----END'
    debug1: identity file /home/user/.ssh/id_rsa type 1
    debug1: identity file /home/user/.ssh/id_dsa type -1

    Could you please give me some clues ?
