    Default ok, behind a router, behind NAT

    Clearly then I am behind my router with this machine.

    Anyone else here running this..with Debian, with dynamic IP, with similar situation? Setting up things to work with my dynamic IP is all that stands between me and a running zimbra installation now.

    A dynamic IP set-up is no different than with a fixed IP, you need to install a local DNS server on your LAN. Follow the instruction for a split DNS set-up in the wiki or 'DNS In A Nutshell' in the forums.

    Bill:

    Thanks...I'll catch on eventually. Not sure if this helps or hinders things, but let me provide more details on my network.

    I run several mailman newslists, from my primary linux box at my office. This machine is 'scott' and the linux box upon which I have installed zimbra is named 'david'.

    Currently, ports 22, 25, 80, 110 are forwarded in my router to 'scott', allowing me remote access for ssh and scp from home, as well to all my email server on 'scott' to process my email, run with exim4.

    Does any of this hinder in any way my attempts here, or is this all simply due to my lack, as of yet, of the proper DNS setup? I am off to read the 'split DNS wiki' entry and see if it sets me straight.

    It won't hinder your efforts to install Zimbra but it will change the requirements slightly. As you will have two mail servers on your LAN you'll need one of them to be authoritative (i.e. the primary mail server), do you intend to retire the exim mail server eventually?

    For this set-up you need to check an additional page in the wiki and that's Split Domain with Zimbra as the primary. DOn't worry about the commands shown there, just try and follow the logic of what you need to do. You will still need a local DNS server, it's postfix that does a DNS lookup to find your mail server and as your on a LAN that IP will be 192.168.1.x - that's where you local DNS will point to.

    Read those two items and if you have any question then post again.
    Regards

    I suppose at some point, once i have Zimbra working well, I could retire my exim mail server; but I am glad to know the status quo can remain intact during the transition. I'll check the two items you mention; my answer likely lies there anyway. I realize Zimbra will have a nicer UI, but for speed and efficiency, I really like reading my mail with mutt.

    Oh, finally, do y'all ever sleep there, or got insomnia like I have?

    Default printing threads

    Is it possible print out a thread with each subsequent message?

    I reran ./install.sh today, after changing some things. Now I receive NO ERROR about DNS...or other errors, but I get the following:

    zimbra@david:~$ zmcontrol status
    Host fyrenice.com
    antispam Running
    antivirus Stopped
    zmclamdctl is not running
    ldap Running
    logger Running
    mailbox Stopped
    tomcat is not running
    mta Stopped
    postfix is not running
    snmp Running
    spell Running
    zimbra@david:~$ zmcontrol start
    Host fyrenice.com
    Starting logger...FAILED


    Starting mailbox...Done.
    Starting antispam...Done.
    Starting antivirus...Done.
    Starting snmp...FAILED


    Starting spell...Done.
    Starting mta...Done.

    What I fail to understand, is how I can run the -status flag and get 'snmp Running' and yet if I run the -start flag it snows 'Starting snmp ... FAILED' .. How can that happen?

    Default after reinstall, still down

    ran ./install.sh -u to remove then reinstalling, and now getting this message:


    Setting defaults...No results returned for A lookup of fyrenice.com
    Checked nameservers:
    24.10.147.163


    DNS ERROR resolving fyrenice.com
    It is suggested that the hostname be resolveable via DNS
    Change hostname [Yes]

    This is odd as I reinstalled the other day, and had NO DNS trouble.

    That would explain the errors in your previous post.

    Check your initial set-up with the following run on the Zimbra server:

    Code:
    host `hostname`   <-- backticks not single quotes
    dig fyrenice.com any
    dig fyrenice.com mx
    and post the results.
    Regards

    dig fyrenice.com mx

    Here are the results, run as user, root and zimbra:

    zimbra@david:~$ host `hostname`
    ;; connection timed out; no servers could be reached

    I know that last week, when I did the install without DNS trouble, this resolved, though I forget to what now.

    'dig fyrenice.com any' returns the following:

    scott@david:~$ dig fyrenice.com any

    ; <<>> DiG 9.3.4 <<>> fyrenice.com any
    ;; global options: printcmd
    ;; connection timed out; no servers could be reached

    likewise, 'dig fyrenice.com mx' returns this:

    scott@david:~$ dig fyrenice.com mx

    ; <<>> DiG 9.3.4 <<>> fyrenice.com mx
    ;; global options: printcmd
    ;; connection timed out; no servers could be reached

    Incidentally, here's something from incoming email..on this zimbra system, while running the dig commands:

    Envelope-to: zimbra@david.fyrenice.com
    Delivery-date: Mon, 30 Jul 2007 08:50:21 -0600
    From: Cron Daemon
    To: zimbra@david.fyrenice.com
    Subject: Cron /opt/zimbra/libexec/zmqueuelog
    X-Cron-Env:
    X-Cron-Env:
    X-Cron-Env:
    X-Cron-Env:

    postqueue: warning: My hostname david is not a fully qualified name - set myhostname or mydomain in
    +/opt/zimbra/postfix-2.2.9/conf/main.cf
    postqueue: fatal: chdir /var/spool/postfix: No such file or directory

    And finally, a reminder about the topology of my office LAN where this merry-go-round is running. I have CABLE from comcast for my WAN IP address. Behind it I have a Linksys RT31P2 router/phone adapter.

    Both 'scott', my primary linux box, and 'david', the one with zimbra installed, are plugged into the Linksys device.

    Ports 22, 25, 80 and 110 at least, are routed to 'scott' while ports 6881, 7025, 995, 993, 443 and 389 are forwarded/routed to 'david' in the Linksys web admin interface. I have mentioned this before, but it's back up the thread a bit.

    Hopefully this will help you in helping me.....

    scott
