From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kanagesh Date: Wed, 20 Oct 2004 07:08:53 +0000 Subject: PPP fails due to IPCP NAK Message-Id: <41760C35.2010804@ncoretech.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ppp@vger.kernel.org Hello, I am using WvDial and PPP to dial out from an embedded board through a modem. On getting the 'Connect' string, PPP is started and initial LCP goes through fine. However, when it comes down to negotiating an IP address, there seems to be a conflict and the connection is terminated. (The debug messages actually show that at one point of time, PPP did receive an IPCP ACK). The board runs on Linux kernel 2.4.18 (patched with arm patch rmk7). PPP version - 2.4.1 I have also added here the debug prints that are shown in /var/log/messages during this attempt. thanks in advance, regards, kanagesh --> Looks like a password prompt. --> Sending: (password) ~&}*Starting PPP Session from 219.65.151.169 to 203.200.15.171}-}*1}=~~[7f]}#@!}!}!} }0}"}&} }*} } }%}&}(<[12]OC)~~&}*Starting PPP Session fr om 219.65.151.169 to 203.200.15.171}-}*1}=~~[7f]}#@!}!}!} }0}"}&} }*} } }%}&}(<[12]OC)~ --> PPP negotiation detected. --> Starting pppd at Wed Oct 20 21:48:06 2004 Oct 20 21:48:06 daemon.notice pppd[183]: pppd 2.4.1 started by root, uid 0 Oct 20 21:48:06 daemon.debug pppd[183]: using channel 6 Oct 20 21:48:06 daemon.info pppd[183]: Using interface ppp0 Oct 20 21:48:06 daemon.notice pppd[183]: Connect: ppp0 <--> /dev/ttyS0 Oct 20 21:48:06 daemon.debug pppd[183]: sent [LCP ConfReq id=0x1 ] Oct 20 21:48:06 user.notice /sbin/hotplug: no runnable /etc/hotplug/net.agent is installed Oct 20 21:48:06 daemon.debug pppd[183]: rcvd [LCP ConfRej id=0x1 ] Oct 20 21:48:06 daemon.debug pppd[183]: sent [LCP ConfReq id=0x2 ] Oct 20 21:48:06 daemon.debug pppd[183]: rcvd [LCP ConfAck id=0x2 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [LCP ConfReq id=0x2 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [LCP ConfAck id=0x2 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x1 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x1 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfNak id=0x1 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x2 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfNak id=0x2 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x3 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfNak id=0x3 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x4 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfNak id=0x4 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x5 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfNak id=0x5 ] Oct 20 21:48:09 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x6 ] Oct 20 21:48:09 daemon.debug pppd[183]: sent [IPCP ConfRej id=0x6 ] Oct 20 21:48:10 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x7] Oct 20 21:48:10 daemon.debug pppd[183]: sent [IPCP ConfAck id=0x7] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x1 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfRej id=0x1 ] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x2 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x2 ] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x3 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x3 ] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x4 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x4 ] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x5 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x5 ] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x6 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x6 ] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x7 ] Oct 20 21:48:12 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x8] Oct 20 21:48:12 daemon.debug pppd[183]: sent [IPCP ConfNak id=0x8 ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x7 ] Oct 20 21:48:13 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x8 ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfReq id=0x9] Oct 20 21:48:13 daemon.debug pppd[183]: sent [IPCP ConfAck id=0x9] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x8 ] Oct 20 21:48:13 daemon.debug pppd[183]: sent [IPCP ConfReq id=0x9 ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0x9 ] Oct 20 21:48:13 daemon.debug pppd[183]: sent [IPCP ConfReq id=0xa ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0xa ] Oct 20 21:48:13 daemon.debug pppd[183]: sent [IPCP ConfReq id=0xb ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0xb ] Oct 20 21:48:13 daemon.debug pppd[183]: sent [IPCP ConfReq id=0xc ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [LCP TermReq id=0x3] Oct 20 21:48:13 daemon.info pppd[183]: LCP terminated by peer Oct 20 21:48:13 daemon.debug pppd[183]: sent [LCP TermAck id=0x3] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP ConfNak id=0xc ] Oct 20 21:48:13 daemon.debug pppd[183]: rcvd [IPCP TermReq id=0xa] --> PPP daemon has died!
