Help: weird DNS problem
Hello,
I have managed to run out of ideas on this one, so I put it out to you:
I have 2 machines networked at home, for experiments, and a set of hard
disks that have various OSes on them. One of them is loaded with 1.2.13
Slackware.
The other machine (that does not change) has 2.0.27 Slackware. Both
kernels are recompiled @home.
I have configured named for both machines in the same way, that is cache
and their own domain each (they have different domains).
I will call the 1.2.13 machine #2 from now on.
When I do dig on #2 it works (with server #2 and #1 if asked). When I do
dig on #1 it works for server #1 but not for #2. I have copied the named
files, incremented serials etc, from #1 to #2 and edited them as required.
There are no differences between them, excepting the host names and
addresses. Same for named.boot hosts.conf resolv.conf. hosts is edited as
required.
The second problem is, that I can't telnet from #1 to #2. The syslog
says that telnetd failed to authenticate the host (#1), by RARP, which is
b..st. RARP works on both machines.
And, as expected, email goes from #2 to #1 but not the other way around
(sendmail SMTP/DNS).
Routes are clean, ftp and everything else works, I have even removed
tcpd from the telnet entry on #2 and restarted it. No joy.
Any ideas ? Is there a bug in one of the distribs that I don't know of ?
(NOTE: Each machine runs only programs from its own distribution. There
are no inode/bad cluster problems, and each machine works well by
itself. Before I used to be able to telnet into #2 from #1).
Peter
