Null Modem Connection Linux <> Win95?

Post by Alex Man » Sun, 16 May 1999 04:00:00



Hi all... Trying DESPERATELY to interconnect two machines.. RH Linux to
Win95 over a null
modem cable.  The two machines are capable of talking over Win95's "direct
cable connection",
but when I try to set up pppd on the Linux box, it won't talk to the Win
machine.  Using the proper
null modem serial cable, Com1 (ttys0) to Com1.  Is there additional software
that's required on
either box to make this work?  The eventual goal is to "modem-share" between
the two boxes, so
pppd is kind of necessary, but I have no clue what authentication procedure
Win95's direct
cable connection follows, so I don't know what to send to the serial port
during the connection
process.

Another option (I think) is to use Win95's "dial up networking" to establish
the connection, and use
the Linux box as a server, but I'm pretty lost as to how to acheive even
THAT goal.  Any assistance
would be greatly appreciated.

The most flexible and easiest way to connect two machines is over
Ethernet.  You can buy ISA Ethernet cards in the US for around $10/each
that will work fine with Linux.

First: Your serial connection would be painfully slow... don't bother.
The reason it's not working is probably the fact that pppd would need
to be set up for whatever weird protocol the Windows box will expect.

Two: I second Mike about getting a couple of $10 Ethernet cards and a)
a hub and a couple of cables, or b) a crossover cable, or c) a piece
of RG-58 and a couple of terminators (id the cards have BNC
connections, then they should come with Ts).

Three: I really doubt that you can "share" the modem.  You can share
the *connection*, though... if the modem is on the Windows box, get
SyGate (www.sygate.com), and if it's on the Linux box, use IP
Masquerading.  There's a HOWTO for setting that up.

Good luck!

Those guys are suggesting you other options ;)

Well, I'm doing exactly what you're trying to do and I like it.
Because, my win95 box is a notebook, the ethernet card for which is still
expensive. Plus, It gives me a 115200 speed connection which is quite
reasonable for using internet with just 2 dollars cable.

However, you can't connect a Linux box with win95 direct cable connection.
It means that you should use DUN(Dialup Networking) and it's much faster.
Visit here:

!!Remember that you should make sure you have a RIGHT cable!!

If this site doesn't help you, mail me.
I'm doing exactly what you're trying to do.
Good Luck!

1. Linux <->Null Modem<->Win95 with PPP

I have been tring to get my pppd in my Linux box setup so that I can
do some serial networking via a null modem cable...  I have tried a
couple of different methods of doing this...

I get the most response out of my machine using the same setup that
was illistrated in the network admin guide (setting up a ppp account
and a pppd script).

If anyone has done this, drop me a line... I could use some new ideas,
new approaches and some help with all these damn messages in the log
files <grin>..

Thanks
