pppd

Oct 23 08:00:55 Orion pppd[658]: The remote system is required to authenticate itself Oct 23 08:00:55 Orion pppd[658]: but I couldn't find any suitable secret (password) for it to use to do so. Oct 23 08:00:55 Orion pppd[658]: (None of the available passwords would let it use an IP address.) ================ pppd от root нечто похожее, хотя файлы /etc/ppp/pap-secrets b chap-secrets присутствуют. Как настроить pppd?
