Re: resolv.conf getting erased

This is something I was messing with months ago, and I have no idea why (or if!) the associated behaviour changed now. Anyways, things seem to be working fine now. We'll see what happens when I plug into eth0 at work tomorrow. I've been working at home all week, just plugged into my work eth0. On resuming from hibernate to disk, only the lo interface was up. I plugged in the ethernet cable and called ifconfig eth0 up. The eth0 network was up, without an IP, and I also had an entry for eth0:avahi: eth0:avahi Link encap:Ethernet HWaddr 00:16:d3:29:0d:aa inet addr:169.254.5.190 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 I then called dhclient eth0, and got an IP on eth0. Everything then seemed to be working, but dns lookups were slow. So I checked resolv.conf, and this time, instead of being cleared of all useful info, it had the dns servers for my work network *and* my home router: tyler:~- cat /etc/resolvconf/run/resolv.conf # 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 nameserver 192.168.2.1 nameserver 140.184.1.21 nameserver 140.184.1.22 search no-domain-set.aliant SMUNET.SMU.CA So now I've got the opposite problem as before - instead of having resolv.conf properly updated, I'm getting the new info appended. Which means I still have to edit the file by hand. Any ideas what's wrong would be most helpful! I will eventually look into automating more of this, but I would like to understand what's going on at a lower level, hence my current efforts to sort this out at with dhclient and ifconfig.

Re: resolv.conf getting erased - every 5 minutes
tyler tyler.sm...@mail.mcgill.ca writes: An update to the problem discussed below: on connecting to my wireless with dhclient ath0, I saw a warning that /etc/resolv.conf was not a symlink to /etc/resolvconf/run/resolv.conf. This was a consequence of having to manually correct /etc/resolv.conf to point at my wireless router for dns. So I deleted /etc/resolv.conf, and replaced it with a symlink to /etc/resolvconf/run/resolv.conf, after confirming that this target did contain correct dns info. Twice in the last half hour since doing this, this file has been cleared - only the comment lines at the top remain, all the dns info is gone. This breaks my internet connection, or at least my ability to resolve addresses. Calling dhclient ath0 restores the file, but this is getting really annoying. Any idea how I find out what is messing up my resolv.conf files? Sorry to be a pest, but I've now determined that /etc/resolvconf/run/resolv.conf is being cleared every five minutes. There is nothing in my leases files, or in dhcp.conf, or in the message I get from dhclient that indicates that the wireless lease should last less than hours/days. This is beyond me, but it's making my computer unusable for anything that requires internet connections. Which is just about everything... Thanks for any suggestions, Tyler -- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org
