RE: Problem setting up a ppp server

As a follow up to this question what exactly should I put in the
options.ttyS0 file ?

My Linux machine has 2 interface cards in it as it acts as the default
gateway for all my locally connected machines.

eth0 is the internal nic with an ip of 172.16.45.1
eth1 is the external nic with an ip of 192.168.254.2

eth0 is connected to the internal hub and eth1 is connected to the DSL
hub/router. The linux box runs DHCP for any locally connected clients with
an ip ragne of 172.16.45.50 to 172.16.45.100. There is one other machine
with a fixed ip address of 172.16.45.2. Other than that any other ip
addresses within the local subnet are free.

I have no idea if the 172.16... subnet is valid for an internal network and
I am quite happy for people to point it out if it is wrong, but I will not
be changing that in the short term, not until I have got this problem sorted
anyway.

Thanks

Simon

Subject: RE: Problem setting up a ppp server


The pppd is only started by mgetty if you specify AutoPPP. I have not done
this yet as I wanted to get mgetty working in basic mode first. What I do is
dial the server and when the connection is established the windows box gives
me a terminal window where I can specify the user name and password. I then
get a command prompt, this is NOT using ppp. The PPP and Serial howtos
explain this quite well. The ppp howto then states that you should do a
setuid on pppd and create a global alias for ppp to call pppd with options.
As I said, this is the least of my problems especially as I will set up
AutoPPP if I can get ppp working.

As for the default gateway setting on my client, which is the important one
for me, I cannot find anywhere to specify this on the dial-up connections
properties. I thought the ppp server would supply this information, just
like it does with dns servers. I cannot find anything on the man page to set
in the options though.

Thanks

Simon

At this point I start to be confused. Why are you running pppd on the
server. That is what
mgetty does. If you have shell access pppd must be running. I just don't
understand what
you are asking. Could you clarify?

The gateway is setup in the client setup on the w2k machine and should be
the ip address
of your server. I do this all the time from my w2k setup at home. Again I am
not sure I
understand what you are doing. How did you configure the ppp connection on
the w2k client?
