    Hi NoDoze,

    Is ssh installed an running on your Server. You can do: "netstat -a | grep LISTEN" to see if port ssh is listening. Or rather do; "Telnet yourserveripaddress 22" from the machine from which you are trying to view the AdminPanel from.

    Good luck..

    Samp try going through the steps shown in this part of the wiki: Regenerating Keys
    This should regenerate your ssh keys, and will also show you steps to verify that they are working.

    OMG! It never occurred to me that is a port 22!

    Yea, I have SSH installed and working....BUT I created my own backup script which uses a ssh key to auto login to the backup server...I TOTALLY deleted the ssh key when creating a new one for the backup server, DUH! LOL

    ...I regenerated the keys... but still no luck...same error. Does the zimbra server need a restarting afterwords...?

    Hmmmm.....

    Yea that would be a problem, something is already listening to the port 22.
    Code:
    lsof | grep ":22"
    should show you the process name and user at least...

    On: Mail Queue Monitoring - Zimbra :: Wiki

    I've done:
    Regenerating Keys
    Verifying sshd configuration
    /etc/hosts.allow
    Another cause, Zimbra account has been disabled

    And still have the same error....

    Uh... you seem to have a talent for having bizarre things happen for you

    Try this one?
    Code:
    lsof -i | grep ssh
    If you can do so, I would also recommend rebooting the server. It might clear up whatever process is holding up the ssh daemon.

    that worked!

    lsof -i | grep ssh
    sshd 7943 root 3u IPv6 2089540 TCP mail.domain.com:ssh->192.168.1.191:50760 (ESTABLISHED)
    sshd 9920 root 3u IPv6 2100808 TCP *:ssh (LISTEN)
    sshd 17575 root 3u IPv6 2150646 TCP mail.domain.com:ssh->static-210-214-136-103.maa.sify.net:43591 (ESTABLISHED)
    sshd 17576 sshd 3u IPv6 2150646 TCP mail.domain.com:ssh->static-210-214-136-103.maa.sify.net:43591 (ESTABLISHED)
    Uhmmm... Do I have a hacker...???

    WTF is this:
    static-210-214-136-103.maa.sify.net:43591
    I dunno what IP that is....!?!

    Did a lookup, got:
    IP address: 210.214.136.103
    Host name: static-210-214-136-103.maa.sify.net

    210.214.136.103 is from India(IN) in region Southern and Eastern Asia

    Ah ha, your system was changing the :22 to :ssh. And if you are connected locally (the 192.168.1.191 I am guessing), and nobody else should be connected then just maybe as you have 2 remote SSH connections coming into your server from outside. You might want to kill those processes and check what was going on...
