Imagine going down for 4 hours, | then getting 4 hour's feed from ten sites simultaneously in the first few | minutes of going back up. Tends to push up the load average a bit, and if | there's anything wrong with the workings of other important software on | the system (i.e. mail) that can make it difficult to address those problems. | | I had thought to put something in rc.local to delay accepting news from most | sites for say 30 minutes after boot; you'd have two nntp_access files, and | boot with a real restrictive one which only allows a few favorite close-by | sites to feed you, which you'd replace with the real one after things quieted | down sufficiently. Before booting: mv /etc/nntpd /etc/nntpd~ After you've been up for a bit: mv /etc/nntpd~ /etc/nntpd Simple, effective. It doesn't prevent the load average hike from happening, but does at least delay it until you want it. Paul DuBois dubois@primate.wisc.edu
