** Description changed:
While resolvconf daemon is running, I cannot use the network, because my
resolv.conf file is filled with invalid nameservers soon after
connection:
========================== bash session: ==========================
# service resolvconf status
resolvconf start/running
# file /etc/resolv.conf
/etc/resolv.conf: symbolic link to `../run/resolvconf/resolv.conf'
# export LC_ALL=C;\
- date;\
- dhclient wlan0;\
- cat /etc/resolv.conf;\
- date;\
- inotifywait /etc/resolv.conf;\
- date;\
- cat /etc/resolv.conf

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

=============================================================================
To clarify servers:
192.168.129.129 is my ISP DNS
8.8.8.8 backup server configured in my router
- 94.25.128.74… what's that?
+ 94.25.128.74… first wimax0 DNS, invalid in my current wlan0 network
- # egrep -nR '94.25.(12|20)8.74' /etc/*
- /etc/resolv.conf:3:nameserver 94.25.128.74
- /etc/resolv.conf:4:nameserver 94.25.208.74
-
- So these last two servers cannot be found in the configs, but somehow
- appear in resolv.conf. They are not delivered by dhclient either. I
- guess they may be root DNSes for my ISP (according to whois info), but
- I'm unable to surf the Internet with their help.
+ # cat /run/resolvconf/interface/wimax0.dhclient
+ nameserver 94.25.128.74
+ nameserver 94.25.208.74
+ # ifconfig wimax0
+ wimax0: error fetching interface information: Device not found
+ # ifdown wimax0
+ ifdown: interface wimax0 not configured
The delay until resolv.conf gets corrupted is not constant at all, sometimes it's as small as 3 seconds. one time is was 13 seconds.
If I reconnect and shut down resolvconf, I get a working network without any problems. This behavior seems to be a regression after apt-get upgrade from ubuntu 11.10 and seems to be a blocker to an ordinary user, since the network is effectively unusable.
