Jack, Thank you for this tip (and also to Mark), switching off peerdns seems to have done the trick. Best regards, Graeme. -- Graeme J Hosking pgp0.pgp Description: PGP signature
[expert] Resolv.conf changing
Hi, I wonder if someone can tell me how to prevent the contents of my /etc/resolv.conf from being re-written every time my NIC is brought up? Or at least, allow me to keep entries in that file that I have put there manually. Basically, the NIC connected to my cable modem has to use DHCP to get its address, etc, etc. But I also run a caching DNS server on that machine. Every time the interface is brought up it will re-write /etc/resolv.conf with settings it gets from my ISP's DHCP server, overwriting my entry to point to the local instance of BIND for DNS lookups. This is frustrating, as the result is that all the machines on my network use my self-hosted DNS server except the machine hosting the DNS server. :) I've read about adding the -R switch to dhcpcd but I wondered if there is another solution? I'm using mdk9.1. Many thanks, Graeme. -- Graeme J Hosking pgp0.pgp Description: PGP signature

Re: [expert] Resolv.conf changing
First up disable a package called tmdns for some reason it's enabled by default.. don't actually remove the package, as every time you configure your network with drakconf, drakconf will reinstall the package.. The commands to disable it.. service tmdns stop chkconfig --del tndns Next edit a file /etc/sysconfig/network-scripts/ifcfg-eth0 and place in there PEERDNS=no for more help to know what you can place in those ifcfg files.. have a look at the man file for ifcfg.. man ifcfg I hope this is a help Cheers Mark On Tue, 2003-09-23 at 10:17, Graeme J Hosking wrote: Hi, I wonder if someone can tell me how to prevent the contents of my /etc/resolv.conf from being re-written every time my NIC is brought up?

RE: [expert] resolv.conf
As I understand it, zeroconf is sposed to be to linux what netbeui is to windoze or what appletalk is to macs. A quick google search shows that is the case. http://www.zeroconf.org/ bascially, when it works, you plug a few mandrake machines into a hub, and they allocate themselves and allow networking with no config work. I don't know if i like it, but i see the reason for it.

I just never noticed the problems from tmdns because all the other network stuff is more forgiving of a bad nameserver in the file. -- Bryan Phinney Software Test Engineer Want to buy your Pack or Services from MandrakeSoft?

[expert] resolv.conf
I am having problems getting SA to do the rbl checks. It appears that my /etc/resolv.conf file keeps getting built with 127.0.0.1 as the first name server. Other network utilities appear to be able to bypass this and try each nameserver before giving up but the Net::DNS perl module is not that smart. It tries the first nameserver, gets a SERVFAIL from localhost and then gives up. I have edited the offending file to move localhost back down but everytime I start the network, it rewrites resolv.conf and adds loopback as the first nameserver. Does anyone know where this behavior is coming from and how I can remove it. I have checked several other boxes with Mandrake 9.1 and none of them appears to even be getting the loopback address in the resolv.conf file but I am not sure how it is happening on this one box so I don't know how to repair it. -- Bryan Phinney Software Test Engineer Want to buy your Pack or Services from MandrakeSoft?
