LINUX<(nullmodem)>Mac PPP connection; LINUX as PPP-server

LINUX<(nullmodem)>Mac PPP connection; LINUX as PPP-server

Post by maarten de boe » Mon, 30 Sep 1996 04:00:00



Hi!

We are trying to run PPP thru a NULL-MODEM connection between
  -PC running LINUX (running kernel ver. 2.0.0, PPP ver. 2.2.0)
    and a
  -Macintosh running FreePPP ver. 2.5 and apple TCP/IP 1.1

Of course, we want LINUX to be the PPP-server and the Mac to be
the client.

This is how far we get:

LINUX:
   as root, we run:

   /usr/sbin/pppd -detach modem crtscts lock :192.1.2.23 /dev/ttyS1
57600

MAC:
   In the terminal window FreePPP recognises the ppp-startup string
   sent by linux. The local IP is also set.
   Anyway, all seems to go well. FreePPP says:
      -establishing communicatiom
      -succesful
      -established communication
      -(short time passes)
      -link dead
      -connection was established but it is not a reliable connection
and
       was terminated.

meanwhile at LINUX:
/var/adm/messages reads:
Sep 29 17:18:34 zorn pppd[147]: pppd 2.2.0 started by root, uid 0
Sep 29 17:18:58 zorn pppd[147]: Serial connection established.
Sep 29 17:18:59 zorn pppd[147]: Using interface ppp0
Sep 29 17:18:59 zorn pppd[147]: Connect: ppp0 <--> /dev/ttyS1
Sep 29 17:19:01 zorn pppd[147]: local  IP address 194.109.45.55
Sep 29 17:19:01 zorn pppd[147]: remote IP address 194.109.6.110

We have the feeling we are quite close to succes... :-}
Can anybody help us out?

Thanks in advance!

1. MAC/PPP <---> FreeBSD PPP --->modem---> ISP

Hi,
  I'm sure this has been asked and answered a thousand times, but I
cannot locate the answer by searching through the archives. I have a
PC box (Cyrix P166+) running FreeBSD 2.2.2, and am using user-level
ppp over a modem to connect to an ISP (dynamic IP). I just got a MAC
(powerPC) and want to connect the MAC to the FreeBSD box, and use the
FreeBSD box as a router to the internet. I don't want to give up user
level PPP, since I have it working perfectly with -auto mode. I use
192.168.64.1 as my FreeBSD box. Also, I have a serial cable which
connects my MAC ModemPort (GeoPort?) to a serial port on the PC
(sio0). I want the MAC and PC to be able to use PPP over the modem
simultaneously, too.  I've seen mention of "proxyarp" but I don't have
any details.  Can someone send me detailed help of how to do this? I'm
sure many out there are probably running similar local nets.
 Thanks,
david
