DNS Caching Server

I'm trying to set up a DNS Caching Server on one of my local machines. I've followed the DNS-Howto (http://www.tldp.org/HOWTO/DNS-HOWTO.html) to the letter, but whenever I start named, it fails.

tail -f /var/log/messages outputs:
Oct 6 17:20:05 Marcus named[29170]: loading configuration from '/etc/named.conf'
Oct 6 17:20:05 Marcus named[29170]: listening on IPv4 interface lo, 127.0.0.1#53
Oct 6 17:20:05 Marcus named[29170]: listening on IPv4 interface eth0, 192.168.0.101#53
Oct 6 17:20:05 Marcus named[29170]: root.hints:33: file does not end with newline
Oct 6 17:20:05 Marcus named[29170]: command channel listening on 127.0.0.1#953
Oct 6 17:20:05 Marcus named[29170]: couldn't open pid file '/var/run/named/named.pid': Permission denied
Oct 6 17:20:05 Marcus named[29170]: exiting (due to early fatal error)
Oct 6 17:21:41 Marcus su: pam_unix2: session finished for user root, service su
Oct 6 17:22:02 Marcus su: (to root) katie on /dev/pts/1
Oct 6 17:22:02 Marcus su: pam_unix2: session started for user root, service su

So I assume this is a permissions problem. I've been doing the whole process by su'ing to root and making changes as neccesarry. Must I actually be logged in as root for this to work, or is 'su' sufficient?

Thanks in advance.

P.S.
This is on SuSE 9.1

I'm not familiar with how SuSE installs bind, but the logfile entries you posted suggest you have 2 problems.

1) root.hints:33: file does not end with newline.

I'd be willing to bet that line 33 is the end of the file.

2) couldn't open pid file '/var/run/named/named.pid': Permission denied

You'll have to check your SuSE init script, but if named is being started as user"named" (like on FC2) then change the ownership/permissions on directory /var/run/named to "named". On my FC2 system the ownership/permissions are set to:

Code:

[root@excelsior run]# pwd
/var/run
[root@excelsior run]# ls -ld named
drwxrwx---  2 named named 1024 Mar 26  2004 named

In fact, the SuSe init script could also be starting named in a chroot'd jail. i.e. -t parameter. If thats the case, you'll have to find the chroot'd base directory from the SuSE init script and then change the ownership/permissions on the corresponding chroot'd /var/run. Again, on FC2 its....

Code:

[root@excelsior run]# pwd
/var/named/chroot/var/run
[root@excelsior run]# ls -ld named
drwxrwx---  2 root named 1024 Oct  3 04:03 named

Note the chroot'd base on FC2 is /var/named/chroot. So all subordinate directories start from that point.

Also, just su'ing to root is all that's needed to start named.

It works now, thanks so much for your hints.
