First of all, I can't access the archive to search information. Second, my question. It seems to me you guys know the answer: Is it bad to make a cname to a cname a in cname b b in cname c c in a w.x.y.z as long as you don't create loops a in cname b b in cname a :) it takes more time to resolve, but it can be done (with bind at least) Should I avoid it, and what reasons can I give to ask them to change the situation? (RFC???) Thanks very much! P.S Me not english speek good _________________________________________________________________ From MAILER-DAEMON Tue Jun 24 04:46:33 2003 Received: from list by monty-python.gnu.org with archive (Exim 4.20) id 19UjRh-0002Xh-6f for mharc-zonecheck-tests@gnu.org; Tue, 24 Jun 2003 04:46:33 -0400 Received: from list by monty-python.gnu.org with tmda-scanned (Exim 4.20) id 19UjRe-0002U7-RE for zonecheck-tests@nongnu.org; Tue, 24 Jun 2003 04:46:30 -0400 Received: from mail by monty-python.gnu.org with spam-scanned (Exim 4.20) id 19UjRd-0002Tj-Dl for zonecheck-tests@nongnu.org; Tue, 24 Jun 2003 04:46:29 -0400 Received: from maya40.nic.fr ([192.134.4.151]) by monty-python.gnu.org with esmtp (Exim 4.20) id 19UjR8-00027d-M7 for zonecheck-tests@nongnu.org; Tue, 24 Jun 2003 04:45:58 -0400 Received: from hyperion.nic.fr (hyperion.nic.fr [192.134.4.116]) by maya40.nic.fr (8.12.4/8.12.4) with ESMTP id h5O8jvNl709081 for ; Tue, 24 Jun 2003 10:45:57 +0200 (CEST) Received: from hyperion.nic.fr (localhost [127.0.0.1]) by hyperion.nic.fr (8.12.6p2/8.12.6) with ESMTP id h5O8jUB5023800 for ; Tue, 24 Jun 2003 10:45:30 +0200 (CEST) (envelope-from sdalu@nic.fr) Received: (from sdalu@localhost) by hyperion.nic.fr (8.12.6p2/8.12.6/Submit) id h5O8jUAm023799 for zonecheck-tests@nongnu.org; Tue, 24 Jun 2003 10:45:30 +0200 (CEST) (envelope-from sdalu@nic.fr) X-Authentication-Warning: hyperion.nic.fr: sdalu set sender to sdalu@nic.fr using -f Date: Tue, 24 Jun 2003 10:45:30 +0200 From: "Stephane D'Alu" To: Discussion about tests performed by ZoneCheck Subject: Re: [zonecheck-tests] alias to an alias ?

(RFC???) > You can refer to RFC1912 p.6 (Common DNS Operational and Configuration Errors): Also, having chained records such as CNAMEs pointing to CNAMEs may make administration issues easier, but is known to tickle bugs in some resolvers that fail to check loops correctly. As a result some hosts may not be able to resolve such names. Sincerly -- Stephane D'Alu
