[-- Attachment #1 --] Hi all, I have a laptop (FreeBSD-4.2-R) that spends a lot of it's time disconnected from the network. When I do want to connect it, I kick off dhclient -- works fine. I recently set up ntpd as a multicast client and discovered that, when the interface (fxp0 in this case) is brought up by dhclient, the machine does not respond to IGMP queries, even though ntpd is listening on 224.0.1.1. ntpd is started at boot time (in the standard rc script way), and therefore fires up well before there is any IP connectivity. It seems to me that the machine should respond to IGMP queries, even though the interface receiving the queries was not up when the socket was opened to listen for multicast traffic..... Any notion of why I might be seeing this? Thanks! --eli [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: This is a comment. iD8DBQE8TehPLTFEeF+CsrMRArfEAKDmGdEItTzM1B//FArlfQVSPsv+dgCg6z5U 3ZK12Sl+EPPCaBmPR4jfvrA= =d6sc -----END PGP SIGNATURE-----
