DNS issues seemingly within OTRS [SOLVED]

[dantheman972]

EDIT: My apologies, meant to post this in "Help", if a mod could please move it.

Hello all, I have an OTRS 3.2 install on a CentOS VM. I recently migrated the VM from a host on one subnet 192.168.1.XX to another subnet 192.168.2.XX and now I'm getting errors from OTRS saying it can't resolve host names. Originally it couldn't resolve our LDAP server making it impossible to log in. To get around that, I just plugged in the LDAP's IP instead of its hostname and now it works. Now I'm getting this error when loading an agent dashboard: "Can't get file from http://otrs.org/product.xml?Product=OTRS-3.2.2: 500 Can't connect to otrs.org:80 (Bad hostname)."

So it seems like it's having issues resolving domain names on our network, as well as the internet as a whole. Funny thing is though, from within CentOS, I can do a dig and resolve the host name just fine:

Code: Select all

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.6 <<>> www.otrs.org

Does OTRS have any DNS settings I need to change or clear? I already tried deleting the cache but no dice. Any advice is greatly appreciated.

it would obey, for instance /etc/resolv.conf

That appears to have done the trick, there was an entry in resolv.conf for an old DNS server on the previous subnet. After I deleted that, restarted the network interface, OTRS and deleted OTRS's cache the link loads on the dashboard. In addition I put our LDAP server's hostname back in the config file and that works now too. Guess that was more a linux issue than OTRS but your assistance is much appreciated none the less.

Thanks,
