I received the following message, but I'm not able to answer myself. If someone can, please send reply to: gromero@andescol.bitnet Here is the message I received: =================================================== From: Gonzalo Romero <GROMERO%ANDESCOL.BITNET@brownvm.brown.edu> Date: Wed, 27 Feb 91 22:25:12 COL Subject: Re: DNS help To: Luigi Rizzo <lr@cs.brown.edu> In-Reply-To: Your message of Wed, 27 Feb 91 22:03:55 -0500 X-Acknowledge-To: <GROMERO@ANDESCOL> Status: RO Dr. Rizzo: Thank you anyway for your answer. We are really new on it, as you can look with our questions. We just have by now a bitnet link for contact you, for example. We have a local network over an ethernet cable, running full TCP/IP protocols, and in it, we have a local decnet with a VMS machine, about five ULTRIX's, 2 IBM RT's, and an IBM PS/2 model 80 with AIX, in which we have put the Name Server because, according to the TCP/IP 1.1 manuals, it supports the MX records. We would appreciate so much if you can put our question on any list or discussion group, because I have put it on several ones, but I haven't received an answer that can help us to solve the trouble. Here is the "/etc/named.*" files of our NameServer: The fist one is the NAMED.DATA file: ;$ORIGIN uniandes.edu.co ; @ IN SOA rtterm.uniandes.edu.co. hsin.andescol.uniandes.edu.co. ( 910201 1800 300 604800 86400 ) IN NS rtterm.uniandes.edu.co. ; localhost IN A 127.0.0.1 andescol IN A 128.1.1.1 andesu6k IN A 128.1.1.54 hugosin IN A 128.1.1.101 vmsing IN A 128.1.25.1 ultrix IN A 128.1.25.2 dfac1 IN A 128.1.25.3 dfac2 IN A 128.1.25.4 dfac3 IN A 128.1.25.5 pegasus IN A 128.1.25.6 tribm IN A 128.2.1.1 rtterm IN A 128.2.1.51 rtgraf IN A 128.2.1.52 aixps2 IN A 128.2.1.53 ; andescol.uniandes.edu.co IN CNAME andescol andesu6k.uniandes.edu.co IN CNAME andesu6k hugosin.uniandes.edu.co IN CNAME hugosin vmsing.uniandes.edu.co IN CNAME vmsing ultrix.uniandes.edu.co IN CNAME ultrix dfac1.uniandes.edu.co IN CNAME dfac1 dfac2.uniandes.edu.co IN CNAME dfac2 dfac3.uniandes.edu.co IN CNAME dfac3 pegasus.uniandes.edu.co IN CNAME pegasus rtterm.uniandes.edu.co IN CNAME rtterm rtgraf.uniandes.edu.co IN CNAME rtgraf aixps2.uniandes.edu.co IN CNAME aixps2 mredadm.uniandes.edu.co IN CNAME mredadm predadm.uniandes.edu.co IN CNAME predadm ; predadm IN A 128.1.11.65 IN MX 10 predadm mredadm IN MX 10 predadm Now the following is the "named.boot" file: domain uniandes.edu.co primary uniandes.edu.co /etc/named.data primary in-addr.arpa /etc/named.rev The 3rd file is "named.rev" : 9999999 IN NS aixps2.uniandes.edu.co. ; $ORIGIN 128.in-addr.arpa 1.1.1.

Now, when you try to PING any machine on the network, you receive the resolution correctly (any A record definition runs OK, but the only MX don't !), and the ping responds OK. We also looked at the "sendmail.cf" file but it don't says anything about MX records or something like it (anymore, the code of this file is almost unreadeable, at least for me!) .... I really thank you in advance, Gonzalo Romero ANDESCOL PostMaster P.S.: Gracias a personas como ud., las redes son como son. Muchas gracias por su ayuda y su interes en colaborarnos en bien de solucionar nuestra noble causa. Disculpenos cualquier molestia que le hayamos podido ocasionar
