Hi There, I have a situation where I'm trying to maintain a PPP connection from my Linux PC to an embedded Linux device. I am able to get the PPP connection working such that each end has an IP address and I can ping the other end for twenty seconds, but then I receive an [LCP ConfReq] packet and the PPP connection sets itself up again. This interrupts the IP connection and breaks my ability to ping. I'm trying to figure out why this is happening, because I want to have a stable PPP connection. If someone can help me I'd appreciate it very much. The embedded device seems to want to restart the connection every 20 seconds. This is what the pppd debug log looks like from my end: ~ # pppd nodetach file /etc/ppp/options.pppUSB1 pppd options in effect: nodetach # (from command line) debug # (from /etc/ppp/options.pppUSB1) dump # (from /etc/ppp/options.pppUSB1) noauth # (from /etc/ppp/options.pppUSB1) /dev/ttyUSB1 # (from /etc/ppp/options.pppUSB1) 57600 # (from /etc/ppp/options.pppUSB1) lock # (from /etc/ppp/options.pppUSB1) noaccomp # (from /etc/ppp/options.pppUSB1) asyncmap ffffffff # (from /etc/ppp/options.pppUSB1) nopcomp # (from /etc/ppp/options.pppUSB1) 10.2.10.5:10.2.10.20 # (from /etc/ppp/options.pppUSB1) nobsdcomp # (from /etc/ppp/options.pppUSB1) nodeflate # (from /etc/ppp/options.pppUSB1) using channel 18 Using interface ppp0 Connect: ppp0 <--> /dev/ttyUSB1 sent [LCP ConfReq id=0x1 <magic 0x913429f5>] rcvd [LCP ConfAck id=0x1 <magic 0x913429f5>] sent [LCP ConfReq id=0x1 <magic 0x913429f5>] rcvd [LCP ConfAck id=0x1 <magic 0x913429f5>] sent [LCP ConfReq id=0x1 <magic 0x913429f5>] rcvd [LCP ConfAck id=0x1 <magic 0x913429f5>] sent [LCP ConfReq id=0x1 <magic 0x913429f5>] rcvd [LCP ConfAck id=0x1 <magic 0x913429f5>] sent [LCP ConfReq id=0x1 <magic 0x913429f5>] rcvd [LCP ConfAck id=0x1 <magic 0x913429f5>] rcvd [LCP ConfReq id=0x6c <asyncmap 0x0> <magic 0xa5a44a5a>] sent [LCP ConfAck id=0x6c <asyncmap 0x0> <magic 0xa5a44a5a>] sent [IPCP ConfReq id=0x1 <compress VJ 0f 01> <addr 10.2.10.5>] sent [IPCP ConfReq id=0x1 <compress VJ 0f 01> <addr 10.2.10.5>] rcvd [IPCP ConfAck id=0x1 <compress VJ 0f 01> <addr 10.2.10.5>] rcvd [IPCP ConfReq id=0x6d <addr 10.2.10.20>] sent [IPCP ConfAck id=0x6d <addr 10.2.10.20>] local IP address 10.2.10.5 remote IP address 10.2.10.20 (there's 20 seconds here where I can ping the other side.) rcvd [LCP ConfReq id=0x6e <asyncmap 0x0> <magic 0xa5a44a5a>] Connect time 0.3 minutes.
