No. You wouldn't want to stick swap in a MFS anyways... it would be silly to swap from RAM to RAM when you could have just left it in RAM to begin with. What you _can_ do: design a MFS that fits within the kernel (the way the boot.flp is built) and stick tcpdump in it. Stick it on a floppy. (I make this sound much easier than it is; I once built a router floppy using this technique and jammed _lots_ of utilities on it; it took all night to get it halfway right). Make sure you have the RAM to support the application. > I have no intention to build a web box.

Unless you have a compelling reason to make this work off of floppy (i.e. you don't have a dedicated machine which implies that you might be a student who is illicitly spying on others without the consent of the school)... I advise that you just pop for the hard disk and be done with it. Much less effort. On the other hand... Web boxes.. interesting concept. ... JG
