Test cases for npppd

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
