SunOS caxy 5.3 Generic_Patch sun4m sparc

Starting a few days ago, telnet connections to my Sparc-10 compatible
suddenly began to take anywhere from a few seconds to a couple minutes
too long.

This happens only from within my subnet/dns domain. In fact, I can
telnet out to an outside host from a Mac or PC and then telnet back in to
my host in less time than it takes to telnet there in the first place.

I can't find anything wrong with my dns (which was my first thought), and
I don't really have a second thought.

Can anyone give me a hint how I might track this problem down?

Thanks much!

(I forgot to say I was running DNS, not NIS.)

Thanks to the many people who sent helpful responses. The upshot:

1) By not having reverse name entries for all my internetted desktop
machines, I am being a Bad Boy. That I didn't even have forward entries
for them is no excuse.

2) Who cares why it never caused a problem before? Why not just create
the entries and not worry about it any more.

The solution was to write a Perl script to generate the dns files from
the bootptab table.

If anyone is interested in such a script, feel free to ask.
