QUIRK XiVO ISO / IncrediblePBX installer issues on systems with PTR records

Kinjo · Aug 17, 2016

In attempt to help others with the same DNS environment I wanted to share:

I found that the current installer - http://incrediblepbx.com/IncrediblePBX13-XiVO.sh with a XiVO ISO base doesn't change the hostname correctly if that system has a PTR record in DNS.

It would appear that somewhere in the base ISO install it does a reverse lookup and writes the FQDN to /etc/hosts in addition to the default XiVO hostname. Then when the IncrediblePBX script attempts to change the hostname it stays as the default "xivo" - which results in a failed install.

My work around was to manually edit /etc/hostname with the corrected FQDN and then remove the extra xivo entry from /etc/hosts, before running the IncrediblePBX installer.

DNS is admittedly not our strong suit, and the XiVO install procedure is unusual. If you have suggestions on how to identify the issue you've raised and address it programmatically, we would be most appreciative.

Unfortunately scripting is not my forte so I won't be much help on troubleshooting the hostname change logic in the IncrediblePBX installer.

The good news is it is easy to replicate the issue without creating a PTR record in DNS. After a base XiVO ISO install edit the /etc/hosts and replace the unassigned:

Code:

127.0.0.1    localhost
127.0.1.1    unassigned.unassigned    unassigned
127.0.0.1    xivo

With a non-xivo FQDN and assoicated system hostname as noted below:

Code:

127.0.0.1    localhost
127.0.1.1    pbx.local.net    pbx
127.0.0.1    xivo

Then proceed with the IncrediblePBX installer. Once you get to the hostname change, this is what you'll see:

Code:

Adjusting hostname to FQDN...
New hostname: xivo.incrediblepbx.com

Please verify no errors shown above in XiVO configuration step.

To continue with installation, press ENTER. Or press Ctrl-C to abort.

After breaking out of the script at this point, I confirmed that both the /etc/hosts and /etc/hostname were untouched. However running "hostname" showed xivo.incrediblepbx.com but running "hostname -f" showed unassigned. Then on a reboot it reverts back to the default xivo hostname.

I suspect the script is expecting one of the following hostname conditions:

xvio with no FQDN entries
FQDN entries with no xvio entries

However in a case with PTRs - it's going to have both xvio and non-matching xvio FQDN entries as described above.

Thanks. Part of the problem is that every single cloud provider sets this up a different way, and I'm still unclear why it should matter to XiVO in the first place.

My pleasure sir and that is a good question. Being my first XiVO install I didn't know what to expect either.

It be nice if they could let us specify the hostname during the base install.
