Testing the uplink

If everything went as it should we should now have a working uplink.

Simply fire up pppd with the right connection and run ifconfig to see if it worked:

pppd call adsl

PPPD output in /var/log/syslog

Note: If you get something like:
Couldn’t set tty to PPP discipline: Invalid argument
Make sure you have the synchronous tty module loaded or compiled into your kernel (I forgot this myself)

Looking at the last 4 lines you can see the connect succeeded. If you have copied my masquerading script you can now enter ‘internet’ on the console and manually configure your normal pc with an internal ip address and the dns addresses you can see in the output of pppd to go online!
