About reverse DNS
 

Hello,

I have 2 questions about how the reverse zones are generated by ispconfig:

1) What triggers the generation of a new zone?
2) What triggers the inclusion of a record in the reverse zone?

The thing is that I have 5 reverse zones in my server when I only have 1 range of Ip's.

Also I don't understand what takes for a domain to be included with a ptr record in the reverse zone.

Thank's in advance.....Larry.

1) A new zone is generated when you add a new zone in dns manager or when you check the create dns checkbox when you add a website.
2) Originally it was the first domain for a specific IP, but falko had changed this in the latest update.

What I am trying o find is when is created a new "reverse" zone (x.y.x.in-addr.arpa)"

I described this in 1)

I am sorry Till but I don´t get it.
I know there is something that I am missing and I don't know what.

If my server has only one IP how come I am going to serve the reverse zone of somebody else IP or IP-range.

Per example:

I have the IP range 200.100.0.192/28
I have one server with IP 200.100.0.196
My reverse zone is 192.0.100.200.in-addr.arpa (set up by my provider)
I have DNS records of domains that I redirect the "www" and MX entries to other servers.
I also manage webs and mail of domains that point to me but I don't have their DNS records.

I had to change the customized/named.conf.master for it to add a "192" before the {ZONE} so it would work for me.

Actualy in my server I have 7 "in-addr.arpa" zones when I sould only have 2, the "0.0.127.in-addr.arpa" and the "192.0.100.200.in-addr.arpa"

Why are the other 5 zones created.

I found out that they are the reverse zones of IP addresses I have asigned to an "A Record" of a domain I host.

Per example:
I have a "A record (WWW)" for a DNS Entry pointing to 82.223.149.150 because the web is served by another company.
This IP is not mine.
ISPConfig creates a "192.149.223.82.in-addr.arpa". ¿?¿?

I could understand if there where as many reverse zones created as IP Addresses are in the "Management-->Server-->Settings-->IP List" plus the "Management-->Server-->Settings-->IP Address" since this are the only IPs the server is going to manage as it does with the "/etc/httpd/conf/vhosts/Vhosts_ispconfig.conf" file (at least if it is connected directly to internet)

Thanks in advance for your time and explanation.

Please update to ISPConfig 2.2.25. It allows you to create the reverse records yourself instead of creating them automatically.

I have now a sistem with IspConfig 2.2.25 installed and working.

I added a "New PTR":
Group: Admin
Title: ono
Folder: admin
IP Address: 213.201.123.86
Hostname: bs1.activa-icard.com

I checked for the entry in /var/named/chroot/etc/named.conf and nothing showup.
I checked for the file /var/named/chroot/var/named/pri.123.201.213.in-addr.arpa and nothing shows up

I include a copy of the /home/admispconfig/ispconfig/ispconfig.log

I don't know why it is not creating the entry and the file.

Any Ideas?
