using the same file, make the following addition to /etc/inetd.conf:

12345   stream  tcp     nowait  nobody    /usr/local/sbin/fileviewer.sh fileviewer.sh /path/to/file/filename

then use this script (note that ^M means C-m, you can do this in vi by
typing C-vC-m in insert mode):

#!/bin/sh
FILE=$1
read x y
while [ "$y"x != "x" ]; do
    read x y
done
cat << EOF
HTTP/1.1 200 OK
Content-Type: text/html^M
^M
<html><head><title>File contents</title></head><body><pre>
EOF
cat $FILE
echo '</pre></body></html>'

an additional tweak might be to change from cat to using tail.  you could
even make it configurable with this:

#!/bin/sh
FILE=$1
read x y
if echo $y|grep tail; then SPEW="tail -100"; else SPEW=cat; fi
...
$SPEW $FILE

anyway once done, just connect to the un*x box via a web server like so:
http://unix.box:12345/  i don't think i used any gnu'isms so this should
work across the boxes you describe.

cheers,

kevin
