I couldn't ssh into my work machine last night, despite having done
so on Saturday. 

auth.log has the following: 

May 30 20:10:01 wivenhoe sshd[12050]: warning: /etc/hosts.deny, line 15: can't verify \
hostname: getaddrinfo(123-456-163-187.bas003.bmt.esat.net, AF_INET) failed

Is this a DNS problem, an sshd config problem or a tcpwrappers
problem? I can resolve the IP number to the hostname but not the
reverse:
brendan@wivenhoe:~$ nslookup 212.2.163.187

Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
Server:		136.201.1.3
Address:	136.201.1.3#53

Non-authoritative answer:
187.163.2.212.in-addr.arpa	name = 212-2-163-187.bas003.bmt.esat.net.

Authoritative answers can be found from:
163.2.212.IN-ADDR.ARPA	nameserver = auth02.ns.esat.net.
163.2.212.IN-ADDR.ARPA	nameserver = sec02.ns.esat.net.
auth02.ns.esat.net	internet address = 193.95.142.60

** server can't find 212-2-163-187.bas003.bmt.esat.net: NXDOMAIN



/etc/hosts.deny has
 "ALL: PARANOID"
as its only relevant content.
