Thread: Error with Admin Console Mail Queue Possible SSHD problem

    Default Error with Admin Console Mail Queue Possible SSHD problem

    Message: system failure: exception during auth {RemoteManager: mail.mymailserver.com->zimbra@mail.mymailserver.com:22} Error code: service.FAILURE Details:soap:Receiver

    A similar error occures when selecting the "mail queues" tab with the following message:

    Message: system failure: exception during auth {RemoteManager: fehr.is-a-chef.com->zimbra@fehr.is-a-chef.com:22} Error code: service.FAILURE Method: GetMailQueueInfoRequest Details:soap:Receiver

    I changed the port from 22 to a different port in the SSHD config file, reason being I was tired of having people brute force attack the server 2300 times per day. is there anyway I can reconfigure Zimbra to use a different port or am I damned if I do, damned if I don't?

    Welcome to the forums,

    Yup - just substitute your port number in the below instructions:

    1. Check /etc/sshd_config and be sure it's set to 22 (or the port you're using)
    2. stop/start/restart sshd
    Code:
    /etc/init.d/ssh restart
    3. su - zimbra
    4. Be sure zimbra's ssh port is set to 22
    Code:
    zmprov ms server.domain.com zimbraRemoteManagementPort 22
    5. Generate new ssh keys
    Code:
    cd /opt/zimbra/bin/
    ./zmsshkeygen
    6. Deploy the keys
    Code:
    ./zmupdateauthkeys
    To test this, you can run the following command:
    ssh -vi .ssh/zimbra_identity -o strictHostKeyChecking=no zimbra@server.domain.com -p 22
    -Shouldn't prompt you for a password at this point...then check the admin console mail queues area/servers/certificates.
    If you continue to get that error please see this doc for some more ideas Mail Queue Monitoring - Zimbra :: Wiki

    I'm not technically unsavy but I am new somewhat new to zimbra and semi new to Linux but from what I gather the directions you gave me are still referencing port 22 for ssh

    You didn't state what port you we're using so I said:

    su - zimbra (or sudo as needed)
    Code:
    zmprov ms server.domain.com zimbraRemoteManagementPort 2233

    Code:
    cd /opt/zimbra/bin/

    I have same error, however, it shows that connection to port 22 has been refused. What can I do?

    your problem seems the same yes, depending on if you have modified the SSHD config. First I would make sure the SSH service is running

    Code:
    ./etc/init.d/sshd status
    if it is not running, issue the start command. if it IS running then perhaps look at iptables or other services that might be blocking it. also you might want to install NMAP to see if the server is actually listening on port 22 (default SSH port)

    nmap localhost

    When I check sshd status, it show this:

    The program 'sshd' is currently not installed. To run 'sshd' please ask your administrator to install the package 'openssh-server'

    My question is, I have followed Zimbra installation guide and Zimbra has been working fine except for the message queue error. Why is this not installed? And what purpose does sshd do?

    Thanks,
    Boon Hong.

    yes, it is not installed and zimbra uses SSH to access the mail queue interface. if you are running ubuntu you will want to do this command

    sudo apt-get install openssh-server

    and that should fix you up. Also make sure SSHD starts with the server by issuing the following command

    chkconfig sshd on

    Let me know if that works.
