this is usually caused by tcp wrappers(most often controlled
from /etc/hosts.deny and /etc/hosts.allow). the best solution I
think is to run a local nameserver and provide forward and reverse
resolution for your local network. A workaround may be to do something
such as:

ALL: 192.168.2.

in your /etc/hosts.allow and/or remove ALL: PARANOID from /etc/hosts.deny.

that format above may not be exactly right its been years since I've
seriously played with tcp wrappers.

but I still reccomend setting up a DNS ..

another workaround at least for telnet may be to just not use
tcp_wrappers(which is fine as long as your firewalled), edit
/etc/inetd.conf and remove the reference to tcpd, and restart it,
that may work too(haven't tried it, and I've been using xinetd for
a while which has it's own tcp wrappers support..)
