Don't forget that nmap will probably need to run as root on a *nix box.
That may be the bigger obstacle. Reading some of the other posts
prompted me to re-read your post. I'm getting the idea that I
misinterpreted your statement "We have a web server..." as indicating
that you have control over it that you may not have. You may not be
able to run your web service as root. You may not be able to modify the
services that run on it.

Can you provide some more details on the target and how much access you
have to it?

One possible solution:
1.) Use Apache Tomcat and have each client request index.jsp instead of
index.html.
2.) In index.jsp, include lines similar to this (I haven't tested it, so
you may have to fiddle with it.):
String cmd = "./nmap -sS -v -O -P0 " + request.getRemoteAddr()
+ " > " + request.getRemoteAddr() + ".txt &";
Process proc = Runtime.getRuntime().exec(cmd);
3.) Figure out how you're going to keep from filling up the web server's
DASD with loads of nmap output. Think also about the processing power
of the server. If 50 clients all connect and run nmap at the same time,
how's that going to affect things? This could quickly turn into an easy
to DoS your own web server.

Another:
1.) Use Apache Tomcat and have each client request index.jsp instead of
index.html.
2.) In index.jsp, include a Server Side Include tag similar to this, but
change the command to something like the nmap line above.
<!--#exec cmd="cat /etc/passwd"-->

There are (>)hundreds of ways to execute something upon (>)hundreds of
events related to a web server receiving a request. Let your
imagination run wild!!

Subject: run nmap automatically from index.html (??)

We are doing a pen test for a small company and wish to automate some
things. We have a website inside their Intranet that
when employees scan or visit it we'd like to nmap the box they came
from trying to see if anyone hooks up an authorized computer to their
intranet. Any ideas of how to get=
nmap to run automatically?

Getting a perl script to run nmap is already done but I'm trying to
figure out whether we should monitor the libpcap data or the apache log
files
etc. I'm sure someone else has done this already - can you share some
ideas?
