You misread the output of free (don't worry, it's a very common mistake). You've actually got about 10MB free; most of what you're seeing is actually buffers and cache. Those will get dumped as you need to load software, but otherwise they're a good thing; you want most of your memory in use, and Linux tries hard to keep "free" memory occupied with cache. > 156 ? 00:00:00 rpc.statd Are you using NFS? If not, you don't need this one (it's from the nfs-common package). > 209 ? 00:00:00 lpd You can probably do without this one, too, unless you need it for a print server. If you like lpr printing, try rlpr instead: no daemon required. > 320 tty2 00:00:00 getty > 321 tty3 00:00:00 getty > 322 tty4 00:00:00 getty > 323 tty5 00:00:00 getty > 324 tty6 00:00:00 getty You can ditch some of these getty's by commenting them out in /etc/inittab. Be sure to leave at least one (I like to leave two). > Is this the best I can expect from linux? What the heck is using all my > memory?

As I said: it's mostly buffers, and you shouldn't worry about it, but you can get rid of some of those daemons to free up a few more bits. M
