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 - - Dave Rivers -
