I was trying to get a PPP connection going with a cisco terminal
server, and this stuff started happening:

Sep  4 05:33:21 dahan pppd[452]: sent [LCP ConfReq id=0x1 <mru 552> <asyncmap 0x0> <magic 0x2352067e> <pcomp> <accomp>]
Sep  4 05:33:22 dahan pppd[452]: rcvd [LCP ConfReq id=0x6b <asyncmap 0xa0000> <magic 0xb94fff2b> <pcomp> <accomp>]
Sep  4 05:33:22 dahan pppd[452]: sent [LCP ConfAck id=0x6b <asyncmap 0xa0000> <magic 0xb94fff2b> <pcomp> <accomp>]
Sep  4 05:33:24 dahan pppd[452]: sent [LCP ConfReq id=0x1 <mru 552> <asyncmap 0x0> <magic 0x2352067e> <pcomp> <accomp>]
Sep  4 05:33:24 dahan pppd[452]: rcvd [LCP ConfNak id=0x1 <mru 1500>]
Sep  4 05:33:24 dahan pppd[452]: sent [LCP ConfReq id=0x2 <mru 552> <asyncmap 0x0> <magic 0x2352067e> <pcomp> <accomp>]
Sep  4 05:33:24 dahan pppd[452]: rcvd [LCP ConfNak id=0x2 <mru 1500>]
Sep  4 05:33:24 dahan pppd[452]: sent [LCP ConfReq id=0x3 <mru 552> <asyncmap 0x0> <magic 0x2352067e> <pcomp> <accomp>]
Sep  4 05:33:24 dahan pppd[452]: rcvd [LCP ConfNak id=0x3 <mru 1500>]
Sep  4 05:33:24 dahan pppd[452]: sent [LCP ConfReq id=0x4 <mru 552> <asyncmap 0x0> <magic 0x2352067e> <pcomp> <accomp>]
[ repeats a couple of times ]

Eventually, this starts happening:
Sep  4 05:33:25 dahan pppd[452]: Received bad configure-nak/rej:  01 04 05 dc
[ more of those, along with ConfReqs and ConfNaks ]

Until finally:
Sep  4 05:33:55 dahan pppd[452]: LCP: timeout sending Config-Requests
Sep  4 05:33:55 dahan pppd[452]: Connection terminated.
Sep  4 05:33:57 dahan pppd[452]: Exit.

So, is it right for pppd to be doing that? I have "mru 552" in my
options file, but I thought that meant "ask for 552, but I'll take
what I can get", not "insist on 552 and refuse to play if I can't
have it". I thought that was the point of all this fancy PPP options
negotiation :)

(Taking the "mru 552" line out of options made it work, btw)
