Reverse lookups failing

[jeffrey_collins at hotmail.com]

I'm using Bind 9.2.3-76 on a Suse server.  Forward lookups work fine.
When I try to do a reverse lookup by IP address from my internal
network using "host 192.168.5.14", I get a "Host
14.5.168.192.in-addr.arpa not found:  2(SERVFAIL)" error message.  I've
verified that the 5.168.192.in-addr.arpa file exists in /var/lib/named
and that my /etc/named.conf file has this entry:

zone "5.168.192.in-addr.arpa" {
	type master;
	file "/var/lib/named/5.168.192.in-addr.arpa";
	};

In the /var/lib/named file I have the following:

5.168.192.in-addr.arpa.	IN	SOA	ns1.myhome.com. me at myhome.com. (
			2006092800
			28800
			7200
			604800
			86400 )

NS      192.168.5.12.
12.5.168.192.in-addr.arpa.	IN	PTR	ns1.sabroso.com.
14.5.168.192.in-addr.arpa.	IN	PTR	zen.sabroso.com.

I'm guessing it's a simple syntax problem in my 5.168.192.in-addr.arpa
file, but can't track it down.  Would appreciate any troubleshooting
tips anyone might have.
