question: This is not on a FreeBSD box. This is on a HP-9000/800 K400, under HP/UX 10.10... Sorry, but I thought someone here might be able to answer anyway. From `netstat -s`: igmp: 0 messages received 0 messages received with too few bytes 0 messages received with bad checksum 13041472 membership queries received 13041472 membership queries received with incorrect field(s) 0 membership reports received 0 membership reports received with incorrect field(s) 0 membership reports received for groups to which this host belongs 0 membership reports sent why isn't the ++igmpstat.igps_rcv_total; line in igmp.c bumping the counter? the /usr/include/netinet/igmp_var.h starts off with: /* $Header: igmp_var.h,v 1.4.89.5 95/04/10 11:33:03 indnetwk Exp $ */ #ifndef _NETINET_IGMP_VAR_INCLUDED #define _NETINET_IGMP_VAR_INCLUDED /* * Internet Group Management Protocol (IGMP), * implementation-specific definitions. * * Written by Steve Deering, Stanford, May 1988. * * MULTICAST 1.2 */ indicating that they simply use a hacked reference implementation, also indicating that the source code base on which HP's igmp is based SHOULD have, and always has had the ++igmpstat.igps_rcv_total; line. the way i read the reference implementation, the membership query counters CANNOT be bumped without the total count being bumped... any ideas? jim -- All opinions expressed are mine, if you | "I will not be pushed, stamped, think otherwise, then go jump into turbid | briefed, debriefed, indexed, or radioactive waters and yell WAHOO !!! | numbered!" - #1, "The Prisoner" ------------------------------------------------------------------------------ Inet: jbryant@tfs.net AX.25: kc5vdj@wv0t.#neks.ks.usa.noam grid: EM28pw voice: KC5VDJ - 6 & 2 Meters AM/FM/SSB, 70cm FM. http://www.tfs.net/~jbryant ------------------------------------------------------------------------------ HF/6M/2M: IC-706-MkII, 2M: HTX-212, 2M: HTX-202, 70cm: HTX-404, Packet: KPC-3+
