I'm suppose you're using PPP and pppconfig for the dialup connection. If so, check your pppconfig setup for that connection. Make sure that "Nameservers" (advanced options) is set to "None". If set to "Dynamic" or "Static", a script in /etc/ppp/ip-up.d messes with your resolv.conf when the connection comes up. Likewise, a script in /etc/ppp/ip-down.d messes with it when the connection is brought down. Note that the latter script is also run at boot time from /etc/init.d/dns-clean. I haven't really had problems with the way this works, but in your particular situation this might cause problems.

I was thinking about making one of my debian digncc> machies a firewall, but don't really know what I would do with it:) Yes a firewall is very useful, because by filtering packets, prevent an outside intruder to access resources inside your network. Inside you may have services running that could be easily hacked, like telnet, dhcp, or Windoze disks sharing. So the firewall separate and link your network to the Internet. Obviously if don't have a network to protect you don't need a firewall :-) For more informations about firewalls look at: http://www.clark.net/pub/mjr/pubs/fwfaq/ http://www.interhack.net/pubs/fwfaq/ About firewalls and routing... There are two types of firewalls: 1. Network level 2. Application level A network level firewall is a router with packet filtering capabilities. Application level firewalls generally are hosts running proxy servers. -- Best regards, Minta Adrian - YO3GIH phone: +401.683.66.52 mailto:[EMAIL PROTECTED]http://www.csit-sun.pub.ro/~gygy/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

VPN
'Lo Folks, In an effort to expand our VPN services, I'm looking at any opensource VPN solution I can find to replace our Shiva box. What I'd love to see is to be able to set up a Linux box with the VPN server software running on it, and to have IPSec compliant clients (wintel, linux, slowaris, mac) connect and have to do authentication via radius (We use CiscoSecure backended by Cryptocards Cryptoadmin server for OTP signon). Is there anything like this out there? I've not been able to find it as of yet... pointers?

Re: VPN
Tim, Take a look at http://www.xs4all.nl/~freeswan/ It's an open source ipsec compliant VPN server. You apply it as a patch to the Linux kernel. It's not packaged because it's a kernel patch, not just a binary.
