pppoe

pppoe -A
pppd pty 'pppoe -S sluzba'

Pokud program spustíme pouze s parametrem -A, pak jen zjistí přítomné AC v síti a vypíše jejich identifikaci.

root@hasan:~# pppoe -A

Chceme-li se na službu připojit, musíme spustit program pppoe , ,přes`` pppd. Oba pak budou komunikovat prostřednictvím standardního vstupu a výstupu.
