Hi This is directed to Brian or possible anybody else who could help me. I have bellsouth.net IFITL. I have been using netgraph with userland ppp since it has been implemented to handle PPPoE (3.4 I think?). Anyways it has been working great for me for quite awhile. My connection has really taken a turn for the worse lately (Bellsouth doing what there good at, I would normally say more here but this isn't a flame war.) And I have noticed my ppp locking up at a certain place and not continuing trying to redial. This is where it occurs: Sep 25 14:24:09 zeist ppp[9872]: tun0: Phase: PPP Started (ddial mode). Sep 25 14:24:09 zeist ppp[9872]: tun0: Phase: bundle: Establish Sep 25 14:24:09 zeist ppp[9872]: tun0: Phase: deflink: closed -> opening Sep 25 14:24:09 zeist ppp[9872]: tun0: Phase: deflink: Connected! Sep 25 14:24:09 zeist ppp[9872]: tun0: Phase: deflink: opening -> dial Sep 25 14:24:09 zeist ppp[9872]: tun0: Phase: deflink: dial -> carrier Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: Received NGM_PPPOE_SUCCESS (hook "tun0") Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: deflink: carrier -> login Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: deflink: login -> lcp Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: bundle: Authenticate Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: deflink: his = CHAP 0x05, mine = none Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: Chap Input: CHALLENGE (16 bytes from XXXXXX_IFITL) Sep 25 14:24:12 zeist ppp[9872]: tun0: Phase: Chap Output: RESPONSE (XXXXX@bellsouth.net) And it will just sit there for hrs and hrs if I don't manually come and kill the process and try to restart it. Unofortunatly this is so frequent that I have experienced over 24 hrs of downtime in a whole 5 days, whoopie for my connection! Here is my ppp.conf file: default: set log Phase Chat IPCP CCP tun command set device PPPoE:dc0 set mru 1492 set mtu 1492 deny pap accept chap disable lqr set timeout 30 set server +XXXX XXXXXXX set speed sync set cd 5 set authname XXXXXXX@bellsouth.net set authkey XXXXXX set redial 15 28800 set dial add default HISADDR disable iface-alias At one time I had LQR packets on and was getting dropped whenever heavy traffic occured. I used to not have this problem. Is it possible that disabling the packets is the reason for the hanging of the ppp? Like I said it can sit in that state right on Chap Output for hrs. I wonder if enabling the LQR packets and just setting a high timelimit on them to send to redback swould help this scenario and atleast get ppp to realize that A) This connection is bunk and is never going to happen cause bellsouth.net is never assigning me an IP and responding and B) try to redial it. Here is my uname info: su-2.03# uname -a FreeBSD zeist.homeip.net 4.4-STABLE FreeBSD 4.4-STABLE #8: Mon Sep 17 05:22:21 EDT 2001 root@zeist.homeip.net:/usr/obj/usr/src/sys/zeist i386 This has been an occuring problem like I had stated for quite along time. Anyways, thanks for the excellent work, FreeBSD Owns all and I'm looking forward to figuring out this little tweak to try to get ppp to act a little more friendly towards a poor IFITL connection, lol. Other then this problem which has been occuring for awhile for me I have had no problems with userland. Really from what I can tell this of course isn't a problem with userland, just a small tweak of a configuration that may help it act better with networks that don't like to assign IP addresses. :) Hope someone can give me some insight or some info on some directions I may take to overcome my problem, thank you. Matt P.S. Sorry about the cruddy wrap on this email, had to post it from a web form since freebsd doesn't like my mail servers cause the reverse doesn't match the HELO, good security.. :) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
