Hello, regarding the looping, I got logfiles from peer side, a Linux box (SuSE Linux 5.3 Kernel 2.0.35) called "Router1". The first part shows a successfull connection to FreeBSD pppd using a ISDN adapter (ELSA Microlinc ISDN). Pppd is configured to use PAP and to be "silent": May 9 21:50:58 Router1 isdnlog: May 09 21:50:58 tei 107 calling hini with myself1 1.EH DM 0,12 May 9 21:50:58 Router1 kernel: isdn_net: ippp0 connected May 9 21:50:58 Router1 kernel: isdn_net: chargetime of ippp0 now 993454 May 9 21:50:58 Router1 ipppd[90]: Local number: 914269, Remote number: 08974299734, Type: outgoing May 9 21:50:58 Router1 ipppd[90]: PHASE_WAIT -> PHASE_ESTABLISHED, ifunit: 0, linkunit: 0, fd: 6 May 9 21:50:58 Router1 ipppd[90]: sent [0][LCP ConfReq id=0x1 <mru 1524> <magic 0x64267842>] May 9 21:51:00 Router1 ipppd[90]: sent [0][LCP ConfReq id=0x1 <mru 1524> <magic 0x64267842>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][LCP ConfReq id=0x1 <auth pap> <magic 0x7acf8d41> <pcomp> <accomp>] May 9 21:51:00 Router1 ipppd[90]: sent [0][LCP ConfRej id=0x1 <pcomp> <accomp>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][LCP ConfAck id=0x1 <mru 1524> <magic 0x64267842>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][LCP ConfReq id=0x2 <auth pap> <magic 0x7acf8d41>] May 9 21:51:00 Router1 ipppd[90]: sent [0][LCP ConfAck id=0x2 <auth pap> <magic 0x7acf8d41>] May 9 21:51:00 Router1 ipppd[90]: lcp layer is UP May 9 21:51:00 Router1 ipppd[90]: sent [0][PAP AuthReq id=0x3 user="xyz" password="xxxxxx"] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][PAP AuthAck id=0x3msg="Login ok"] May 9 21:51:00 Router1 ipppd[90]: Remote message: Login ok May 9 21:51:00 Router1 ipppd[90]: bundle, he: 0 we: 0 May 9 21:51:00 Router1 ipppd[90]: sent [0][IPCP ConfReq id=0x1 <addr 0.0.0.0>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][IPCP ConfReq id=0x1 <addr 193.31.21.1> <compress VJ 0f 01>] May 9 21:51:00 Router1 ipppd[90]: sent [0][IPCP ConfRej id=0x1 <compress VJ 0f 01>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][IPCP ConfNak id=0x1 <addr 193.31.21.2>] May 9 21:51:00 Router1 ipppd[90]: sent [0][IPCP ConfReq id=0x2 <addr 193.31.21.2>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][IPCP ConfReq id=0x2 <addr 193.31.21.1>] May 9 21:51:00 Router1 ipppd[90]: sent [0][IPCP ConfAck id=0x2 <addr 193.31.21.1>] May 9 21:51:00 Router1 ipppd[90]: rcvd [0][IPCP ConfAck id=0x2 <addr 193.31.21.2>] May 9 21:51:00 Router1 ipppd[90]: local IP address 193.31.21.2 May 9 21:51:00 Router1 ipppd[90]: remote IP address 193.31.21.1 The second part shows a looping connection.
