External Modem / PPP Problems.

Mandrake 10.0 Community.

I have an external modem that works well under Linux.
If I use kppp, I get connected fine.
Problem - none of my web-browsers or my kmail program can use the connection. I get unknown host messages.
ifconfig tells me the ppp0 interface is up but if I go into the MCC to set up a modem connection, it fails.

Any ideas?

Did you set up DNS properly?
Try 'ping www.google.com' and 'ping 64.233.161.99'. If the first doesn't work, and the second does, you will need to setup the DNS. You will probably need the DNS addresses of your ISP. Then you can put them into KPPP.

The dns is fine. /etc/resolv.conf is overwritten with the correct dns numbers by kppp. Thanks, though.

I have the same problem (with mdk 10), but when I create a new connection in MCC (after closing the non-working one) by browsers and e-mail clients work well. Of course it is not very efficient to open the MCC and create a new connection each time I want to reach the internet. So I am also interested in a clean solution to this problem.

(This problem appeared after I upgraded from mdk 9.1 to mdk 10.)

I had the same problem but i found out that it was ethernet to blame.
Ethernet was up and all the applications was not paying attention to the modem.
If you have ethernet try (as root) ifdown eth0 or ifconfig eth0 10.10.1.1 netmask 255.255.0.0 .

ifconfig only said I had lo and ppp0 up, but I tried ifdown eth0 and that didn't help.

Interestingly, if I try ifup ppp0 as root, I get "ppp0 failed error 2"
Man ppp gave me nothing.

I have a partial solution to my (our ?) problem:

As root type ifconfig when the modem is connected. Then note the device (say ppp0) and the inet address (say aaa.bbb.ccc.ddd)

Then type
route add default gw aaa.bbb.ccc.ddd ppp0

It worked for me, but when I log off and log in I have to do it again.

I've wimped out - a fresh install of 10.0 Official has cured all.
