Ok -
I have a machine that is my gateway to the outside world (using
natd.) This machine contacts my ISP every now-and-then to grab
news and mail.
So, this machine (and all of the others on my network) have a
/etc/resolv.conf for pointing to the ISP's nameserver.
But - at any given time, the gateway machine isn't likely to
be connected to the network...
This is completely fine, until I try to rlogin to the gateway
machine (ponds.dignus.com). The rlogin's have to timeout doing the
normal rhosts verification... which can take a long time, since
I'm not running a resolver (bind) at my end. Of course, I'm using
an internal (10.0.0.xx) network... so the ISP shouldn't be able to
resolve this anyway...
Now - the typical answer is, of course, "You need to set your
/etc/host.conf to use the /etc/hosts file first, then use bind.
Well - I have that set up - my /etc/host.conf looks like:
# $Id: host.conf,v 1.2 1993/11/07 01:02:57 wollman Exp $
# For our situation, use /etc/hosts first...
hosts
# Then, use the nameserver
bind
# If you have YP/NIS configured, uncomment the next line
# nis
My entries are present in my host file...
What's strange is that things on the gateway machine seem to access
the local network (presumably using /etc/hosts) just fine. It's
only rlogin's to the gateway machine from the internal network
that are causing the problem...
Also, if I don't ifconfig the external slip connection, I don't
have this timeout behaviour...
I guess, what I'm hinting at here, is that /etc/host.conf doesn't
seem to be working for the r-cmds...
Has anyone seen this behaviour?
Are the r-cmds using their own resolver? And thus "by-passing"
/etc/host.conf?
Is something else going on?
- Thanks -
