I'm thinking it's a peer bug, but I'm not sure, and I can't do anything about the peer, as it's a consumer service by an apparently disinterested service provider who refuses to resolve problems if "unsupported" software is used. Can anyone suggest anything? Is there somewhere in pppd source where I can easily disable this response, in case I can continue the existing connection? The debug and dump output is here; http://quozl.linux.org.au/mm-5100/2005-08-12/rtt-fail.log (the SIGHUP after the restart is generated by my ip-down script) The pppdump output is here; http://quozl.linux.org.au/mm-5100/2005-08-12/rtt.pppdump The service I'm using is a CDMA 1x RTT modem attached by USB; http://quozl.linux.org.au/mm-5100/ pppd is from Debian GNU/Linux sarge, 2.4.3-20050321 Linux kernel 2.6.11.7 on i686. Problem is reproducible; most easily if there is a PPTP session active on another interface and packets begin to be sent over the new interface as a result of a route change, but also during normal operation without any PPTP session active. Sometimes it will operate for minutes or hours, sometimes only seconds. The trouble always begins with an LCP ConfReq out of the blue, and generally in apparent response to some packet sent by my end. --=20 James Cameron http://ftp.hp.com.au/sigs/jc/ --IMjqdzrDRly81ofr Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFC/FDWIiWKUhK+Mj4RAl3KAJ9Yvcr7D6A/BmSRRjAIVTHMW+utewCgkYqi HlLSPXBuWE4LxAJe8rwvynM= =WK+r -----END PGP SIGNATURE----- --IMjqdzrDRly81ofr--
