I have been using Newsguy's dialup ISP service for sometime now and\nhave been happy with it, until last month when my Linux box could no\nlonger establish a ppp connection. The symptom was that pppd errored\nout with "LCP: timeout sending Config-Requests". I had been running\npppd version 2.4.1, upgrading to 2.4.3 did not help.\n\nThe strange thing is that I can connect to the Atlanta numbers\n(e.g., 678-538-1522) without issue, but the problem does show up on\nthe Augusta, Georgia line (706-849-0578). The Augusta line is on the\nMegaPOP network which is owned by Starnet ([URL="http://www.starnetinc.com"]www.starnetinc.com[/URL]).\n\nSo, I enabled my pppd's debug option to see what was going on. With\nthe Atlanta number, all is well:\n\n\nrcvd [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x923d695a> <pcomp>\n<accomp> <auth pap>]\nsent [LCP ConfAck id=0x1 <asyncmap 0x0> <magic 0x923d695a> <pcomp>\n<accomp> <auth pap>]\n\n\nBut, there is a problem with the Augusta number:\n\n\nsent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xc473d9d7> <pcomp> <accomp>]\nrcvd [LCP ConfReq id=0x1 <mru 1501> <asyncmap 0xa0000> <auth pap>\n<magic 0xfd874513> <pcomp> <accomp> <mrru 1524>\n<endpoint [local:22.214.171.124.2d.6c.6e.73.31]>]\nsent [LCP ConfRej id=0x1 <mrru 1524>]\n\n\nAfter which point the host (peer from my machine's perspective) seems to\nignore my machine's ConfRej message and simply reissues its previous\nConfReq options until my machine times-out. I am not sure if the ppp\nsoftware these ISP's use is even capable of full negotiation (that\nmight be too much to ask). However, unless they do negotiate, they\nshould not default to multilink operation (<mrru 1524> above) which\nis for use with multiple modems (so as to get a ppp multiline\nconnection over 56Kbps).\n\nThe behavior of the Augusta ppp host seems to me to be a violation\nof ppp standards. Specifically, section 5.1.1 of RFC1990\n([URL]http://www.ietf.org/rfc/rfc1990.txt[/URL]) states:\n\n\nThe presence of this [mrru] LCP option indicates that the system\nsending it implements the PPP Multilink Protocol. If not rejected,\nthe system will construe all packets received on this link as being\nable to be processed by a common protocol machine with any other\npackets received from the same peer on any other link on which\nthis option has been accepted.
