SuSE 9.0: Internet connection sharing

vbraca · 03-14-2004, 05:55 PM

Hi,

I have problems setting up /srv/www/cgi-bin/internet.html script to share my internet connection in a home network.
I can access it from both machines but nor the list of providers nor the status of smpppd service appears.

I've setup smpppd and smpppd-c conf files but still when I press connect - nothing happens ?

Even tried to edit file mannualy and to add interface and provider myself - still nothing - any ideas ?

Have you considered using iptables for routing instead of the suse configuration?

Iptables/Firewall settings are O.K. - if I connect mannualy both machines can access Internet through gateway Linux machine.

I'm looking for a solution how to set smpppd-web package to allow my wife to control connection from her WinXP box.

Done !!!

Script was meant for specific machne setup though distiributed as part of official SuSE distirbution.

If anyone needs help with this one feel free to contact me anytime.

Regards,

Is there anyway you can post a short description of how you solved the problem? This would be greatly appreciated and extremely helpful!

Here is adapted script for my configuration. Everything works execpt for selecting providers/ISP so I guess someone else could help with this one. So far my provider is selected as default one in /etc/sysconfig/network/ifcfg-ppp0

For /etc/smppd.conf add lines:

open-inet-socket=yes
host-range="x.x.x.x x.x.x.x."
#leave empty for no authentication
password=

Also language selection has been striped from script since I use English/Serbian only.
