Re: reveal IP connection source from bruteforce authentication attempt

Ok, what does that 1:1 NAT setting look like? Do you really need that? If you only have one public ip on the WAN interface, you don't.

Re: reveal IP connection source from bruteforce authentication attempt

There's your problem. Delete those rules and port forward all of those ports to your Zimbra server.

Re: reveal IP connection source from bruteforce authentication attempt

What do your port forwarding settings look like in pfSense?

Re: Migration ubuntu Server 14.04->16.04 on a Zimbra 8.8.10

I'd recommend doing a clean install of 16.04 instead of doing the upgrade. If you partition the server correctly, ie put /opt on a separate partition, then it's very easy to do and you don't need to restore the /opt/zimbra directory(although you should always have a current backup).

Re: Clean and empty ZCS 8.8.9 Server and Ubuntu 16.04 issues

How is your disk subsystem setup? Hopefully not RAID 5. I'd also recommend disabling apparmor.

Re: Migration Options

As long as you are staying with the same flavor of Linux, ie Ubuntu > Ubuntu or CentOS > CentOS, all you need is the /opt/zimbra directory and the ldap database, the exact same Zimbra version, and for the new server to have the same hostname and ip as the old. I've done this many times without issue...

Re: Restore Data

If you can't pull the hard drive out of the server and access it in another machine, and you don't have a backup of /opt/zimbra on an external backup source, I'm afraid there is no information to upload to the new server.

Re: Zimbra 8.6.0 DNS migration problems

Did you restart Zimbra after reconfiguring the server with the new DNS settings?

Re: Zimbra 8.6 Single Server upgrade - upgrade failure

At this point, I'd backup /opt/zimbra and any other data needed, and do a fresh install of Ubuntu 14.04. Be sure the hostname and ip address remain the same. After Ubuntu is installed and /opt/zimbra is restored, rename /opt/zimbra to /opt/zimbra.live and run the Zimbra 8.6 installer for 14.04 with ...
