Help I want to use the Redhat box as follows :

[Windows XP] ---> TCP/IP or SAMBA ---> [Redhat 9.0] ---> Modem ---> end.

I want to create "virtual com ports" or something on my XP machine and use a certian app to dial an end point Redhat 9 must then actually use a modem on /dev/ttyS0 to dial the end point ...

Windows must think it's got a modem installed but actually it is on the Redhat box.

The end results will be to have a modem bank ( 2 or 3 modems ) on the redhat box and let 10 Windows XP machines use it as if they had modems connected to them.


Any help will be appreciated.

I assume you mean internet sharing via the redhat box. You will need to build a NAT with port forwarding, a dns caching/resolving server, and I believe diald will help you to dial on demand.

Try these links below.

I am actually want to dial into SUN Solaris boxes all over the show ...

I have 10 technicians with Windows XP machines , I want to use my Redhat Box in the server room , connect 2 or 3 modems onto it and let the guys use that "modem bank" to dial out to the clients , thus no need to give all of them analog lines etc.
