It consists of 2 shell scripts: 'recursls' (something like a filtered
'find [<path>] ! -type d') and 'getsums' which produces a md5sum list
(see below).

It requires another package which may be found here: 
http://www.zelow.no/floppyfw/download/packages/chksum/chksum.bz2

I run it like this:

# ssh root@floppyfw-inside getsums / | sort -k2 > md5sums.2001-12-27

It produces a list of files with their associated md5-checksums:

285b0ecf99c9b71f5884295a2c6e75dd  /lib/ld-2.1.3.so
24509abf9763ae7cf273b365a0d8894e  /lib/libc-2.1.3.so
a17b6dfe8125987fc207320949387a7d  /lib/libcrypt-2.1.3.so

I do a diff with previous version(s) of the list to check if
there have been any changes I'm not aware of. A very simple
intrusion detection system.

Out of box, it installs in /usr/bin, in which case no pre-*.ini
or post-*.ini script is required; if you don't like that, you'll
have to write a post-microids.ini script to move it somewhere
else.

Should you have any comments and/or questions, throw them at me
and I'll try answer to the best of my abilities ;-)
