[oclug] pppd

[Strosberg, Bill]

Greg:

It was mentioned before, but check that /proc/sys/net/ipv4/ip_forward
contains 1.  There's been a change in the /etc/sysconfig/network parameters
(in RedHat, anyways) to enable ip forwarding, and the previous FORWARD_IPV4
parameter doesn't work any more.

You have to put net.ipv4.ip_forward=1 in /etc/sysctl.conf to enable
forwarding in newer versions, but most documentation still uses the old
conventions.  If you check out the contents of /proc/sys/net/ipv4/ip_forward
you get the true picture.

what I used was 

pppd /dev/cua0 57600 passive local debug logfile ppp-log 192.168.0.1:

in my case my machines IP was 192.168.0.1 and the other machine on the
subnet 
was 192.168.0.99

now you mentioned that the palm to linux connection should be on a different

subnet.  Why is this?  Can I not use the same subnet?  As I mentioned I can 
communicate with the linux box the palm is connected to. But my broadcast 
didn't seem to work. Just noticed I can set a netmask option for the pppd, 
thought the default was 255.255.255.255.

Maybe this is the problem.  My outgoing broadcast message from the palm
would 
only work if the destination address was 192.168.0.255.

Again to clear up my goal is to send an broadcast message from the palm and 
have a process on the linux box as well as another computer on the same 
subnet reply using unicast.
