Yes. As for getting the NICs to cooperate, just specify which is which like this (/etc/modutils/local) : alias eth0 tulip options eth0 io=0xdc00 irq=11 alias eth1 tulip options eth1 io=0xde00 irq=10 By specifying the IO (determined from 'dmesg') I can ensure that I know which card is which interface and they'll be plugged in to the correct ethernet segments. (I specified IRQ because by default they were sharing one, and I had a spare so I thought "why not?") | However, can it effectively run Apache?

If you're doing complex dynamic building of web pages then more details are needed. For example, zope would not run terribly well on that 133, I don't think (especially if you had an RDBMS to query on it too). | (It won't be running any GUI apps whatsoever, so the only things running | will be the various daemons and an instance of emacs.) Sounds good to me. I've got a 486SX (25MHz) with 8MB RAM at my parents' home handling NAT. It sometimes runs dhcpd and I tried making it my secondary MX (exim). dhcpd runs fine, when it runs. The main problem I've had is the load getting too high (thrashes like mad) and the kernel starts killing things. That happened when I first set it live with exim because I didn't configure it right (no load limiting options set) and mail servers around the world tried to offload a 4-day queue undelivered mail (eg debian-user and several other lists) because my primary was offline. Then the little machine tried to fork a delivery process for each message, but my primary was offline. That half-killed the machine. I couldn't do a thing since sshd and every other daemon was killed by the kernel in an effort to stay alive. (Hint: plan better than I did) I've also tried running samba on it. It can't be done from xinetd because windows times out before it finishes loading samba from disk (and thrashing all through the process). I don't know how bind would fare because I didn't know anything about setting it up when I setup that router. In fact, I know of one debian user in particular who runs spamassassin on a pentium class machine with 24MB RAM. Of course, it does shoot the system load sky-high when he tries to fetch 1K+ messages at once and takes about a half-hour to process them all, but that is extreme usage.
