Howdy folks,
I think I've run into a bug in the FreeBSD resolve libraries.
All error messages are from /var/log/messages.
(We use "bounce-xxx" as a temp hostname here at UF).
Here's the bsd uname info:
[jfh@bounce-bsd:/] 22 % uname -a
FreeBSD bounce-bsd.cis.ufl.edu 2.0.5-RELEASE FreeBSD 2.0.5-RELEASE #0:
Fri Sep 8 16:17:01 1995
root@bounce-bsd.cis.ufl.edu:/usr/src/sys/compile/KERNEL.EDO.IRQ i386
On to the problem:
-------------------------------------
On freefall.cis: (you get r.arpa)
[jfh@freefall:~] 93 % rsh bounce-bsd ls
Permission denied.
[jfh@freefall:~] 94 % grep freefall /etc/hosts
128.227.224.32 freefall freefall.cis.ufl.edu
On the bsd machine, syslog reports:
Sep 22 12:07:31 bounce-bsd rshd[3282]: jfh@r.arpa as jfh:
^^^^^^^^^^
permission denied. cmd='ls'
---------------------------------------
On redbug.cis: (you get ddr.arpa)
[jfh@redbug:~] 5 % rsh bounce-bsd ls
Permission denied.
[jfh@redbug:~] 6 % grep redbug /etc/hosts
128.227.224.18 redbug.cis.ufl.edu loghost
On the bsd machine:
Sep 22 12:28:15 bounce-bsd rshd[3308]: jfh@ddr.arpa as jfh:
^^^^^^^^^^^^
permission denied. cmd='ls'
---------------------------------------
On tick.cis: (you get -addr.arpa)
[jfh@tick:~] 3 % rsh bounce-bsd ls
Permission denied.
[jfh@tick:~] 4 % grep tick /etc/hosts
128.227.224.30 tick.cis.ufl.edu tick loghost
On the bsd machine:
Sep 22 12:31:40 bounce-bsd rshd[3314]: jfh@-addr.arpa as jfh:
^^^^^^^^^^^^^^
permission denied. cmd='ls'
---------------------------------------
Here are the reverse pointers:
freefall: 32.224.227.128.in-addr.arpa
redbug: 18.224.227.128.in-addr.arpa
tick: 30.224.227.128.in-addr.arpa
But, for some reason, if you line up the hostnames two spaces ahead
of 'in-addr.arpa,' you get the above pattern:
freefall (r.arpa)
in-addr.arpa
^^^^^^
redbug (ddr.arpa)
in-addr.arpa
^^^^^^^^
tick (-addr.arpa)
in-addr.arpa
^^^^^^^^^^
Anyone else seen or know about this bizarre bug??
This machine is running as an nis-client to SunOS 4.1.3 NIS, and is
one of our hosts.equiv.

P.S. Apparently, it's just keying on the host name, not the domain, as I
tried this from "gibson.ucet.ufl.edu" (hostname as long as "redbug"), and
also got "ddr.arpa."
