I try to create a co-domain to test a site before moving all dns entries to the new server, so my setup is: DNS: www.domain.tld --> old server www2.domain.tld --> new server (ISPC based) I create a co-domain www2. Unfortunately is does not show up. In the apache2/vhost directory, I find the www2 ServerAlias in a file Vhosts_ispconfig.conf with a timestamp. In the Vhosts_ispconfig.conf without a timestamp www2 is gone, but the change date_time of both files are the same. So, it looks like it gets added, but also immediately removed. So, I thought I remove all www2 entries in ISPC, do-domain, dns all cleared, also empty-d the recycle bin. Then start from fresh. Now I get an error entry already exists. Looking for www2 in /etc/bind shows that the rDNS file still holds the www2 entries. So, up to the database.... and yes www2 is in there also. Looks like the delete function of codomain does not clear all entries? Any suggestions? Insight? Am I on the wrong track?
