I would suggest a 4GB drive as a proxy caching and news spool. Well, at clubnet and interworld we're using 3 3g drives for news and still can't keep 10 days of some alt groups :-) Remember to add the '-l' flag to expire if you're spreading news across filesystems. (between Christmas and New Year's we got 650mb/day of alt alone for several days in a row; it's tapered off for now to a "sane" 350...) INN "can" run in a 16m machine but then nothing else will (I've done this on an SGI :-(. We run INN and apache (with 14 alias/virtual hosts now) on the same (P120 FreeBSD) system at clubnet with no problems (in 32m ram), but the web hit rate is still pretty low. If it starts creeping up we'll split that off. (try www.turkeyrack.com or www.macom-phi.com for an example :-) A "good" 486 running INN can keep up with a T1 easily if you don't have more than 2 or 3 big feeds. The thing that'll get you is passive outgoing feeds using slurp; if anyone does that there's a cute secret - turn off dbzincore for nnrpd. That change alone cuts your load average a bunch... (and encourage them to go over to psl, which is much easier on the server, and easier for them to control too.) (note that regular news readers never trigger dbzincore anyhow since they don't do msg-id requests). Another hint - use INN with the streaming patches, at least if your bulk provider has them. You can run a full feed on a 56k but there is little room for fixing hangups (the news flood after a crash of either your server or another big one anywhere on the backbone can be awesome). -- Pete
