We'll return to todd@zeta.org.au and All's
discussion of PPP troubles

 to> This is what happens when i try and run net-start.

 to> [root@ozzy bin]# net-start
 to> bash: /usr/local/bin/net-start: No such file or directory

 to> bash: /usr/local/bin/net-start: No such file or directory

What is net-start supposed to do?  I haven't seen this command.  On my
Linux box, network services are loaded in the rc scripts on startup and
for the PPP connection, I either use a default (configured using diald)
login to the Net, or I manually run a script to connect to the network
at work (all PPP scripts are "home grown", I trust them more that way :)
).

Loos like you have a network. :-)  Mine looks similar, except for having
an official IP address on eth0 and a phantom sl0 interface used by
diald. :-)

Your default route goes via your Ethernet?  Shouldn't it be going out
through the PPP link?  Try adding the "defaulteroute" option to your
pppd commandline.


 to> After Logging off.
-----------------------

Looks pretty normal, though I wouldn't have a default route pointing to
your Ethernet, unless it leads elsewhere.  My default route points to
the sl0 interface, and appears as though I'm still connected to the Net,
but this is because I'm using diald.  Without diald, I wouldn't have a
default route, which would be fine (if it's not on the LAN, it doesn't
exist! :) ).

 to> [root@ozzy ppp]# cat options
 to> lock


 to> Any help, greatly appreciated.

Try adding defaulteroute to your pppd commandline (or /etc/ppp/options
if you will only ever use one PPP connection), and remove your static
default route (which serves no useful purpose). If you do happen to have
multiple LAN segments (common in a company LAN), use specific static
routes to route to them, as you should know the address ranges and
gateways used on the LAN. Leave the default route pointing towards the
Internet. :-)
