Open BSD 3.3 Change DNS from Master to secondary

I have ab old OpenBSD 3.3 Unix server hosting DNS. I have limited experience on this server. Now we are making some major changes on my network which is forcing me to make some changes on this server.

1- Presently this BSD server is a master DNS for many domains. I have a windows server as the secondary. How do switch it and make the Windows the master of those domains and BSD the secondary for those Domains in DNS on the BSD?

2-How do I switch the domain on the OpenBSD?

Thanks,

It's not really matter of OpenBSD, it's rather issue of the DNS server you use on it.

If it's Bind, you need to make changes on named.conf file (i.e. /var/named/etc/named.conf), and change entries from master to slave (see named-simple.conf as sample).

Example:
#slave needs to specify where the master is
masters { 192.168.1.10; [...;] };

Next, you can/should check/update /etc/resolv.conf, /etc/hosts and /etc/myname.

It is a bind DNS. OK I get how I will make it a slave but who becomes the master? Does my Windows which is secondary become master? I want to make my WIndows server master instead of secondary.

Also, what about switching domains?

DonKoyote

You need to configure your Windows Server as a master for your domain. Then, configure your hosts to use both servers as a DNS servers (master - Windows Server, slave - OpenBSD).

When you say master Windows and Slave OpenBSD--do you mean primary windows and secondary OpenBSD? sorry I just want to make sure.

Also, if I want to switch this server to anther domain, how would i do it?

That answes my DNS questions. I'll let you know how it goes.

The actual OpenBSD is in domain company.com as an example. How would I move to us.company.com.

How do I change the domain this server is in??

DonKoyote

As I mentioned earlier, OpenBSD machine just needs /etc/hosts, /etc/myname, and /etc/resolv.conf files to be reviewed. All other changes depends on what services does it serves (i.e. MTA, POP3, HTTPD... etc.).

All depends if you serve any services on OpenBSD machine. It's not like on Windows Servers or Windows Hosts in the Active Directory domain.

one more question. How do I change the IP address of this server? These changes are happening this weekend so I want to make sure I have everything covered.

DonKoyote

OpenBSD has all network card configuration in /etc/hostname.if file where "if" is a network adapter three letter name (see ifconfig command output). Change IP and mask to your needs and run /etc/netstart.

I don't see anything called hostname in the etc directory.

ASKER

I foud it in a file called rc.conf in ETC. is this where I need to make these changes.

DonKoyote

If it's correctly configured OpenBSD, you should see hostname.* files in your /etc/ directory.
If not... I can't describe all possible configuration methods used on your OpenBSD machine.

Show me output of "uname -a", "ifconfig" and "ls /etc/host*"

(By the way, this is going far away from the topic...)

IFCONFIG COMMAND IS NOT WORKING? WHAT AM i DOING WRONG? I WAS ABLE TO DO AN LS FROM WITHIN ETC BUT IT WOULD NOT LET MAKE CD INTO HOST.

Really need your help on this one for this weekend. Thanks

DonKoyote

As I thought, we are talking about wrong system :)

You have a FreeBSD, not OpenBSD.

So how would I make those changes to the network IP?? Is the DNS changes the same?

DonKoyote

Modify your rc* file for network configuration changes and rest should be the same.
