Dear colleagues, Yesterday we'd found/stepped on a bit of trouble: on some of our FreeBSD-based routers (hundreds of vlans, etc): Oct 20 22:12:46 <ntp.notice> gwn4 ntpd[86421]: ntpd 4.2.4p5-a (1) Oct 20 22:12:46 <ntp.err> gwn4 ntpd[86422]: Too many sockets in use, FD_SETSIZE 1024 exceeded Actually, machine has to listen on 123 on just 2-3 interfaces (two upstream vlans and lo0), but googling leads me just to -L option which is not described in the manual page nor seams to work (I did not look at the sources yet though). Is there any way to restrict interfaces on which ntpd is listening (modulo jail, which has another/orthogonal set of restrictions)? As usual -- thanks in advance! :) -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
