Re: /etc/resolv.conf, /etc/ppp/resolv.conf, dhcp3-server and dnsmasq

Folk,

I tried to reply via the link on the Web page of the list using a Win 98 system. The message failed to appear. Hence this message. According to advice, the subject line will allow the list processor to connect the thread. If it fails, please don't tell me to maintain the thread rather than start a new one.

Doug,

Thanks. resolvconf has been present since long ago. After your message I purged it, reinstalled and tried ppp again. (Oddly, purging resolvconf did not remove /etc/resolv.conf.)

No dice. /etc/ppp/resolv.conf has two nameserver addresses but they are not copied to /etc/resolv.conf after ppp connects. Of course, if I
cp /etc/ppp/resolv.conf /etc/resolv.conf names are then resolved; but as you say resolvconf should do this or something similar. Also, the addresses are not removed from /etc/resolv.conf when ppp disconnects. Also, this is in syslog at startup.
Warning: /etc/resolv.conf is not a symbolic link to /etc/resolvconf/run/resolv.conf Since when is /etc/resolv.conf a link rather than a file?

So perhaps this is the problem: if /etc/resolv.conf is the link, it gets updated automatically for a new connection. If it is a file, it is left unchanged.

Luckily a cable modem is also available. If connected to the 'net through eth0, /etc/resolv.conf gets the nameservers for the cable ISP. So the problem is with ppp but not with eth.

Do you need help?

Name resolution worked until about the time I tried udhcp, dhcp3-server and dnsmasq. I wonder whether one of these installations changed something in /etc/ppp/ or resolvconf.

In principle, name resolution is a simple concept. Pity that the implementation is so tangled. Any ideas to solve this appreciated.

Thanks, ... Peter E.
