hello,
i'm using a dialup connection to internet, it works fine in winxp/win98, i just have to put the dns of my isp. in linux Mdk 9.0 i use the same configuration as in win xp, ie, pap authentication, i enter the dns but i only receive 74 bytes. nothing is working : pop3, http,....

the command route -n gives only this (with 1st isp)
Destination Passerelle Genmask Indic Metric Ref Use Iface
xxx.xx.31.61 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
the ip : xxx.xx.31.61 is the remote host ip.

and the ifconfig command gives (second isp) :
[root@home t]# ifconfig

lo Lien encap:Boucle locale
inet adr:127.0.0.1 Masque:255.0.0.0

[root@home t]#

i have the same problem with both isp's

i'm sure the problem is within my installation, but don't know what to do
any help appreciated
thanks

What kind of modem is it? What sort of results do you get when you ping the outside world?

If you want to do it the command line way, have a look at this article.

hi,

is my problem due to the ip...xxx modules running? i really don't know why they are running, since my machine is not a server.

try this
route del default
route add default ppp0

and then try it
