on my laptop, at times when I switch from X to vty0, I see (e.g.): Oct 18 08:27:07 g1-227 kernel: rn_addmask: mask impossibly already in treern_addmask: mask impossibly already in treern_addmask: mask impossibly already in treern_addmask: mask impossibly already in treern_addmask: mask impossibly already in treern_addmask: mask impossibly already in treern_addmask: mask impossibly already in tree... I see where the message is issued (sys/net/radix.c:539 @r210122, last updated 2010-07-15 14:41:59Z). As this is a laptop, and thus subject to being connected to networks I do not control, I run a packet filter on it, and the one with which I happen to be most familair is ipfw. Thus that's what I use. So it's possible that either ipfw or routing is driving rn_addmask(). However, I'm unclear on: * What (specifically) is actually causing this. * Whether or not it's enough of an issue or problem that I should take evasive action. Put differently: what is my exposure here? * If so, what sort of evasive action is appropriate for me to take. I suppose I could try a packet-capture, but the lack of timestamps make correlating the message-issuance with particular packets a little more challenging than I'd prefer. I note, too, that I'm running a very similar ipfw configuration on the packet-filter machine here at home; while I find the above- quoted whines in /var/log/console.log on the laptop, I do not find them mentioned in that file for the packet filter machine. Clues? [Please include me in the recipient list, as I'm not subscribed to net@; I've set Reply-To as a hint.] Thanks! Peace, david -- David H.
