PPP: "Re: IPCP with mobile ISP sometimes gives bogus DNS address"

[Markus Becker <mab comnets uni-bremen de>]

Hi all,

several 3G cards (e.g. from Option) are reporting 10.11.12.13 as DNS 
server, when they are not yet attached to a network, as you probably know, 
see http://marc.info/?l=linux-ppp&w=2&r=1&s=bogus+DNS&q=b

There seem to be 2 possible solutions to this:
1) Patch PPP to accept MS-WINS settings and use high values for 
ipcp-max-configure, ipcp-max-failure, ipcp-max-terminate and/or 
ipcp-restart. See 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=445711 .
(I am using the mentioned patch currently. Works fine for me.)

2) Checking with AT command CGATT, whether the device is attached to a 
network and only try to dial in when this is true. 
(http://marc.info/?l=linux-ppp&m=121305432406467&w=2)

In order to get this fixed, I have several questions:

a) The Debian bug report states, this has been sent upstream. Has upstream 
accepted, denied or forgotten about it? Is there an upstream bugzilla for
linux-ppp?

b) Marco, could this patch be part of the Debian package? Dan, how is this 
done in Fedora?

c) Dan, could solution 2 be integrated into NM?
