samba - Jan 1998 - Hostname lookups fail when hostname is all numeric!

Hi all!

I'm using Samba 1.9.17p4 on Solaris 2.5.1 and have been pretty well off so
far
(except for printing, but that is another story).  Anyway, I was playing around
with what I'm calling smbwall (was ~/extra/misc/wall.perl) which allows
messages
to be sent to all hosts connected to the samba server.  Anyway, I noticed that
my machine was NOT getting these broadcast messages. After a little research,
I found that we've got two machines that have the following hostnames :

02634211
02802771

Neither of these machines are able to get these broadcast messages.. All the
other machines that I tried have the same style hostnames, but have a
"p" on
the front making them in the following format :

p02634782

Anyway, it appears that samba is messing up the hostname lookup somehow for
hosts that have no alpha characters on the front part of the name.  I suspect
that if I were to change my machine name to have the prefixed "p" that
the
problem would go away.  However, that is not an easy option currently.  I've
been poking around in the name lookup sources thinking the problem would be
easy to spot, but I haven't found anything interesting yet.  I've been
looking
at the sources to 1.9.18p1 so far, and will be installing it later today. I
don't know if that will fix this problem -- I suspect not.

Any ideas?

>From RFC 952 (DOD INTERNET HOST TABLE SPECIFICATION):
   1. A "name" (Net, Host, Gateway, or Domain name) is a text string
up
   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
   sign (-), and period (.).  Note that periods are only allowed when
   they serve to delimit components of "domain style names". (See
   RFC-921, "Domain Name System Implementation Schedule", for
   background).  No blank or space characters are permitted as part of a
   name. No distinction is made between upper and lower case.  The first
   character must be an alpha character.

Not "should be an alpha character", "must be..."!
