Linux/Mac PPP

Linux/Mac PPP

Post by Schlatter Marti » Tue, 11 Mar 1997 04:00:00

I've a problem with a dialup connection to one of our customer
which run mac's on his side. When he tries to download a 2Mb
file via ftp from my linux server, the ppp appears to hang
(even ping does not return).

Here is my environment:

- Linux Caldera 1.0
- Zyxel Elite
- /etc/ppp/options:
  asyncmap 0

I have no problems connecting to our system and ftp these files
from another linuxbox or event NT-Systems.
Has anybody experience in this area? Please let me know!

Thanks, Martin

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


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:

   as root, we run:

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

   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
      -established communication
      -(short time passes)
      -link dead
      -connection was established but it is not a reliable connection
       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
Sep 29 17:19:01 zorn pppd[147]: remote IP address

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

Thanks in advance!
