provate APN (no dns

[bartek w]

Hi All
Its over a 2 weeks i figthing with connecting my system to private APN in
GSM network (gprs connection). It seems that problem lays in how pppd
works...

In if one would like connect to public APN just to use internet, send proper
AT command, tries to connect, there is an PAP autentification and then
system obtaion DNS and IP throug IPCP...(APN "internet") When calling
private APN i've got
IPCP timeout probably becouse system offers only IP.. (maybe I'm wrong)
i've tries to also add ms-dns option, but it doesnt help

In win32 everything works smoothly without any error. Could you advice??
please...

Data:
ubuntu kernel 2.6.17
modem: siemens ES75(mc75) on COM1 (ttyS0)

messeges, debug and setup files are here:

any question please ask, acces to system -no problem - i need help....

The ms-dns option means you offer to supply the DNS servers to the peer
rather than the peer supplying them to you.

Excerpt from logs/debug:

Nov 7 16:39:39 STAWOZ-client pppd[4816]: rcvd [PAP AuthAck id=0x1 "TTP Com PPP
- Password Verified OK"]
Nov 7 16:39:39 STAWOZ-client pppd[4816]: sent [IPCP ConfReq id=0x1 <addr 0.0.0.
0> <ms-dns1 0.0.0.0> <ms-dns3 0.0.0.0>]
Nov 7 16:39:42 STAWOZ-client pppd[4816]: sent [IPCP ConfReq id=0x1 <addr 0.0.0.
0> <ms-dns1 0.0.0.0> <ms-dns3 0.0.0.0>]
Nov 7 16:39:43 STAWOZ-client pppd[4816]: rcvd [IPCP ConfRej id=0x1 <ms-dns1 0.0
.0.0> <ms-dns1 0.0.0.0>]

[with many repeats of the last two line]

Looks like the peer isn't going to provide DNS servers and pppd won't
give up asking for them so as a result you aren't getting an IP address.
I've never had to use the pppd option "usepeerdns" but I think pppd
should accept the ConfRej and just ask for the IP address. If so then
this pppd is broken. I can say the source code for pppd 2.4.4 here,
obtained from ftp.samba.org, does not have a "dns3" - it uses dns1 and
dns2 as one might expect.

That said try removing the "usepeerdns" option to get past the trouble,
or better, get a pppd that is not broken. Unfortunately, distributions
sometimes tamper with programs and break things...
