Test cases for npppd

pppoe.md

Test PPPoE on a standalone OpenBSD

This test

• assumes /etc/npppd/npppd.conf is kept the original.
  • uses 10.0.0.0/24 for pool address for npppd
• uses rdomain 1 for client PPPoE

1. System configuraions

   $ doas sysctl net.inet.ip.forwarding=1
   $ doas sysctl net.pipex.enable=1
   

2. Create pair(4) interfaces for test

   $ doas ifconfig pair0 up
   $ doas ifconfig pair1 patch pair0 up
   

3. Append the following setting to /etc/npppd/npppd.conf

   tunnel PPPoE protocol pppoe {
       listen on interface pair0
   }
   bind tunnel from PPPoE authenticated by LOCAL to pppx0
   

4. Create a test user "test" with password "hogehoge"

   $ echo "test:password=hogehoge:" | doas tee -a /etc/npppd/npppd-users
   

5. Start npppd

   $ doas npppd -dd
   

6. Start pppoe0

   $ doas ifconfig pppoe0 rdomain 1 0.0.0.0/32 0.0.0.1 \
       pppoedev pair1 authproto chap authname test authkey hogehoge up
   

7. Test if success

   $ npppctl session brief
   Ppp Id     Assigned IPv4   Username             Proto Tunnel From
