Sorry. I was trying to keep it short. Linux, of course. Debian etch for amd-64
/etchosts has a 127.0.0.1 localhost grassmann line plus a line 192.168.0.21 grassmann.harke.org grassmann and similar for my other machines on this lan every thing on this lan has fixed IP address One mystery solved. /etc/resolv.conf has the IP addresses for openDNS But I don't know how they got there. The file is dated 10/20 so it might be from when I used the wifi at Borders. I had to change my interfaces file and do a ifup ath0=borders to get connected. Could that have given permission to rewrite /etc/resolv.conf? I guess I could check this out the next time I'm at Borders. I used wireshark to trace the net happenings. I just retried with the net connected to see if there was any follow up to the DNS query. For firfox, er iceweasel, there was but for a card game no follow up.
