DNS Slave Issues on Fedora

I recently updated one of my servers to Fedora Core 2, and one of its jobs is to provide DNS slave service. I could not for the life of me figure out why I was getting the following message when sending zone notifies:

Oct 11 17:11:44 saturn named[30297]: received notify for zone 'guyton.net': 
                not authoritative

The main problem was that I didn’t follow convention with ns records, so I fixed them up. Still nothing fixed, but I got things in better shape, theoretically.

It turns out that Fedora’s named runs chrooted to /var/named, even though there is an /etc/named.conf file. That’s misleading – you really need to edit the /var/named/chroot/etc/named.conf file. That in itself didn’t fix things, however:

Oct 11 21:45:47 saturn named[31267]: transfer of 'guyton.net/IN' from 10.1.1.14#53: 
                failed while receiving responses: permission denied
Oct 11 21:45:47 saturn named[31267]: transfer of 'guyton.net/IN' from 10.1.1.14#53:
                end of transfer

I had to chgrp named /var/named/chroot/var/named; chmod g+w ... so that the replicated zones could be written as the named user.

Problem solved, but it took some tinkering. I found a couple of other items that were improved upon in the process, so it was not a bad thing. I also softlinked /etc/named.conf to /var/named/chroot/etc/named.conf so that it would remain obvious.

Double-Network Linux Installation

Wow, Linux installations have come a long way in the past few years. I won’t dredge up the past, but the present certainly needs mentioning:

  • I downloaded Fedora Core 2 ISO images
  • I mounted them as loopback devices and dumped the contents all to one directory
  • I set up that directory for NFS export
  • I burned disc one for initial boot
  • I booted the new server with the CD with this command:
    linux vnc askmethod
    

    This did nothing at first, but eventually asked me the type of install I wanted – NFS to the server I had already set up.

  • Then the cool part – it started a VNC server on port 5901 for the gui choices.
  • I went downstairs to my laptop in front of the TV, grabbed an alcoholic beverege, and proceded to choose packages on my remote (wireless) network display.
  • Currently as I type, my remote display is telling me that the new server is pulling install files off the older server and installing Linux.

That’s so cool! I view my display over the network to the new server, which is pulling packages over the network from the NFS server.

For what it’s worth, it’s not a big box – just a 450 MHz P-II with 256 MB RAM. But it’s got two new 80 GB drives mirrored – nice again – the Linux install was able to do software RAID and LVM on everything.

I love being a geek.

Halloween Wigs

I went to Party City today to pick up a few things, and I passed through the wig section. Hilarious! Two of note: Enormous Afro and Deluxe Mullet. They also had “Comb-over” and a nerd ‘do. Funny.

I got a cool plastic warhammer for $8, but it looks like Zachary owns it now…
