Sometime on Dec 18, banaja assembled some asciibets to say:
I want to set up MODEM in my Linux server.
and use it as a proxy server for other machines.
There are howtos on the subject.
First, there are the modem howtos: http://linuxdoc.org/HOWTO/HOWTO-INDEX/hardware.html#HWMODEMS
Then there's the dial up howtos: http://linuxdoc.org/HOWTO/HOWTO-INDEX/networking.html#NETDIALUP
The routing howtos: http://linuxdoc.org/HOWTO/HOWTO-INDEX/networking.html#NETROUTING
the security howtos: http://linuxdoc.org/HOWTO/HOWTO-INDEX/networking.html#NETSECURITY
You should read through the relevant sections of the above documents, and then come back with specific questions. For example:
I set up my modem to connect to vsnl, and I can dial out perfectly, but I'm having trouble resolving hosts, and downloading mail.
