Debian doesn't have /tmp/resolv.conf.auto but here is the
answer.
peter@joule:~$ ps aux | grep dnsmasq
dnsmasq 5278 0.0 0.0 2328 592 ? S Aug08 0:00 /usr/sbin/dnsma
sq -u dnsmasq -r /var/run/dnsmasq/resolv.conf
peter 6774 0.0 0.0 3120 728 pts/0 S+ 07:56 0:00 grep dnsmasq
>From the manual.
-r, --resolv-file=<file>
Read the IP addresses of the upstream nameservers from <file>,
instead of /etc/resolv.conf. For the format of this file see
resolv.conf(5) the only lines relevant to dnsmasq are nameserver
ones. Dnsmasq can be told to poll more than one resolv.conf
file, the first file name specified overrides the default, sub-
sequent ones add to the list. This is only allowed when polling;
the file with the currently latest modification time is the one
used.
And finally.
peter@joule:~$ cat /var/run/dnsmasq/resolv.conf
nameserver 64.59.160.[]
nameserver 64.59.160.[]
Last field omitted from the addresses in respect of the ISP.
Strangely, the manual, FILES section, lists /etc/resolv.conf
but not /var/run/dnsmasq/resolv.conf.
I should have thought to check ps yesterday. All that
is left in this story is to understand why dnsmasq
uses /var/run/dnsmasq/resolv.conf rather than
/etc/resolv.conf. Appears to be specific to Debian;
not in other distributions. Is this a consequence of
Debian policy?
Thanks again, ... Peter E.
