Hi, I encounter an chap authorization problem using pppoe3.8, ppp 2.4.4b1 and Freeradius 1.1.3. The relevant logs are: PPP dump: Nov 15 17:43:29 localhost pppd[7486]: rcvd [LCP ConfReq id=0x2 <magic 0x1b31752> <pcomp> <accomp> <callback CBCP>] 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Nov 15 17:43:29 localhost pppd[7486]: sent [LCP ConfRej id=0x2 <pcomp> <accomp> <callback CBCP>] Nov 15 17:43:29 localhost pppd[7486]: rcvd [LCP ConfReq id=0x3 <magic 0x1b31752>] 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Nov 15 17:43:29 localhost pppd[7486]: sent [LCP ConfAck id=0x3 <magic 0x1b31752>] Nov 15 17:43:29 localhost pppd[7486]: sent [LCP EchoReq id=0x0 magic=0xbe000118] Nov 15 17:43:29 localhost pppd[7486]: sent [CHAP Challenge id=0x2 <dd114655881b93c9111ba4122068632faa63f98d>, name = "localhost"] Nov 15 17:43:29 localhost pppd[7486]: rcvd [CHAP Response id=0x2 <3e7ffb922fcba977f3dc8c2418d7dec2>, name = "test1"] 00 00 00 00 00 00 00 00 00 00 00 00 Nov 15 17:43:29 localhost pppd[7486]: rc_avpair_new: unknown attribute 60 Nov 15 17:43:31 localhost pppd[7486]: Peer test1 failed CHAP authentication Nov 15 17:43:31 localhost pppd[7486]: sent [CHAP Failure id=0x2 ""] Nov 15 17:43:31 localhost pppd[7486]: sent [LCP TermReq id=0x2 "Authentication failed"] Nov 15 17:43:31 anton pppd[7486]: rcvd [LCP TermAck id=0x2] 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
