[pkg-wicd-maint] Bug#894509: /usr/sbin/wicd: Setting static DNS with custom nameservers works only for a few minutes

[Neels Hofmeyr]

Package: wicd-daemon
Version: 1.7.4+tb2-5
Severity: normal
File: /usr/sbin/wicd

Dear Maintainer,

In wicd-gtk, I set the wired interface Properties as:

  [x] Use static DNS    [ ] Use global DNS servers
  DNS domain    [                        ]
  Search domain [                        ]
  DNS server 1  [9.9.9.9                 ]
  DNS server 2  [8.8.8.8                 ]
  DNS server 3  [                        ]

I disconnect, then re-connect. Above DNS servers are used, and I see them in
/etc/resolv.conf fine.

After some time though, presumably after DHCP refresh, the nameserver in
/etc/resolv.conf is set back to the DHCP server's idea of what nameservers I
should be using (in my case 192.168.0.1).

In my current situation, the DHCP server's DNS is broken, and thus name
resolution stops working as soon as the static name servers are dropped, which
is why I noticed this behavior quite prominently.

In the olden days, I would edit /etc/resolv.conf manually, and it would stay
put. Currently though resolv.conf seems to get overwritten regularly
(presumably by DHCP), and I had hoped that wicd would help me keep it static.

Thanks for taking a look!
