[bitfolk] Networking issue

Hi This is puzzling me. I have been on a server attempting to set up radicale but nothing to interfere with the networking function of the server - as far as I knew. On purging the installation and attempting to download the apt version I found that it couldn't connect to apt-catcher. DNS was obviously foobarred, as was the internet with no pings or traceroute. Logged in via the console and got internet back up and running by re-adding the gateway to ip route. I'm then attempted to get DNS working. The configuration at /etc/network/interfaces looked ok. auto eth0 iface eth0 inet static address 85.119.83.xx netmask 255.255.248.0 gateway 85.119.80.1 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 85.119.80.232 85.119.80.233 Nothing in /etc/resolv.conf. I've tried reloading interfaces by installing resolvconf and -d and -a with no joy. I could dig using the Bitfolk DNS on the command line, i.e. dig @85.119.80.232 www.google.com, but standard DNS queries timed out. I then added the Bitfolk DNS manually to resolv.conf, rebooted and I was still without name resolution as resolvconf is now controlling the file and had deleted my entries! # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN I fixed this by adding nameserver entries to the resolv.conf.d/head, rebooted and DNS working but no internet. Added the gateway again and everything is finally working - fingers crossed. Thank goodness for console access! Any ideas as to the best approach to fix this properly please and any idea what I could have done to wreak such havoc? TIA Steve -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
