Debugging PPPOE Problems

PPPOE is used mainly for handling connections via Digital Subscriber Lines (DSL).

To debug problems regarding PPPOE, connect the router to the DSL modem and check that the Internet LED at the front panel is lit. If not, check cabling.

Now you have to login to the router to get access to a console for entering commands. Use telnet or ssh.

First, enable syslog on the shell prompt:

syslogd -OP $(tty)

This should give you at least one line of output saying that syslog is now enabled.

Second, check the DSL connection. To do so we use the command line version of rp-pppoe. Hint: Disable the DSL connection in your WRT54G's setup menues otherwise there may be more than one pppoe client running concurrently.

Try:

pppoe -I vlan1 -A

This should print the name of your DSL access concentrator.

Alternatively try:

pppoe -I vlan1 -d

These commands my fail with one of the following messages:

  • Timeout waiting for PADO packets.
  • Timeout waiting for PADS packets.

In this case, ... more help to come... have to sort out first!
