My home system runs ppp-2.2.0.c with a 1.2.13 kernel. ppp gets loaded as a
module at boot time, and the kernel has IP forwarding compiled.

I want to:

    - dial up my home system from host 203.25.235.1 (at work), and login to an
      account that starts up a ppp link;

    - on my home system, add a network route (not default route) for
      203.25.235.0 over the ppp interface.

The first part I can do, no problem. To handle the second part, I put the
following in /etc/ppp/ip-up, on my home system:

case $5 in \
203.25.235.?|203.25.235.??|203.25.235.???) \
    route add -net 203.25.235.0 gw 203.25.235.1 netmask 255.255.255.0;; \
esac
exit 0

According to the pppd man page, ip-up gets called with several parameters,
with the fifth one equal to the destination address. Also, according to the
man page, ip-up gets executed only after the link gets established.

My problem is that the ip-up script above doesn't work. pppd executes the
script (with source address 192.168.0.1; destination address 203.25.235.1), the
ppp link gets established, but netstat -rn doesn't show a network route,
only a host route.

But if I execute ip-up "by hand" as root, once the link is established,
netstat *does* show the network route (as well as the host route), and pings
to any hosts on 203.25.235.0 get sent via the ppp interface, as expected.

Can someone shed some light on this, and say what I need to do to get ip-up
to work when pppd executes it?

Thanks,

Carl.

You need to speify the full path to the route command.
(ie. /sbin/route add -net ......   )

I set my routes up with the default route always pointing at ppp0 and  
the local network addresses pointing at eth0. 
I figure anything outside my home network will fail when ppp0 is down anyway.

One other thing  do you have #!/bin/sh  at the start of the ip-up script?

I just let pppd define the default route dynamically, by using the
'defaultroute' option.  When the link's down, attempting to access any
address outside the Ethernet results in "network unreachable", and the
process aborts quickly and cleanly. :-)

No need to run route either.  pppd will look after it all. :-)

It will, but having the default route entry removed when the link goes
down is a bit cleaner. :-)
