Looks like the other side is semi-broken. It's interpreting 0x21 0x45 as a two byte protocol ID, whereas really it's a one byte compressed protocol ID (0x0021) followed by the first byte of an IP packet (0x45). That's clearly broken, because only the last byte of a protocol ID can be odd. Perhaps it's not expecting the 0x0021 to be protocol-compressed... the MPPE RFC (3078) is silent on whether or not that's allowed. Try the patch below and see if that helps. You might also report the bug to whoever maintains the Linux PPP daemon. -Archie __________________________________________________________________________ Archie Cobbs * Packet Design * http://www.packetdesign.com --- sys/netgraph/ng_ppp.c.orig Thu Nov 21 12:39:06 2002 +++ sys/netgraph/ng_ppp.c Thu Nov 21 12:39:26 2002 @@ -744,7 +744,7 @@ case HOOK_INDEX_VJC_VJIP: if (priv->conf.enableCompression && priv->hooks[HOOK_INDEX_COMPRESS] != NULL) { - if ((m = ng_ppp_addproto(m, proto, 1)) == NULL) { + if ((m = ng_ppp_addproto(m, proto, 0)) == NULL) { NG_FREE_META(meta); return (ENOBUFS); } To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
