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

</div>Very strange. Operating system? Distribution? Anything unusual? What does<br>
hostname report? What is in /etc/hosts?<br>
<br>
My best guess (with very little info) is that you are trying to find localhost<br>
and failing.<br>

</div>Apparently? Strace? Wireshark? How you tracked it down would be helpful.<br>

</div>Ugly. Try adding your hostname to the /etc/hosts entry for 127.0.0.1<br>

</div>Anything that displays X (or runs inside of a new xterminal) needs to find the<br>
$DISPLAY, which might well do a hostname lookup to set/check the display.<br>

</div>I'm a fan, certainly much faster on average than what pacbell provides. Where<br>
does your laptop/router get it's IP? Static? DHCP from your network<br>
provider? If it's dhcp then you are getting the DNS servers from your dhcp<br>
provider, if not then someone likely followed the opendns directions for your<br>
router/laptop.<br>
<br>
I wouldn't be terribly surprised if say a linksys router installed with a<br>
community linux distribution like openwrt defaulted to using opendns as a server.<br>
