ad-hoc web server

Hi,
~
In order to avoid viruses and things I use knoppix to access the
internet
~
Now, sometimes I need to setup an ad-hoc web server to show case some
work. I don't need a domain name to be resolve, nor do I need this
permanently
~
I thought all I had to do is:
~
1) set up my router to forward http request to port 80 to the IP
address of the internal box where I
~
2) have a service running accepting connections and serving pages on
port 80 from a USB external drive
~
But when I went to check this from a local internet caffee I was
404'ed
~
What else do I need to do?
~
Thanks

I am not sure if I DNATed or not, but I did set up the router to
forward external requests on port 80 to the internal address of the
box (192.168.1.???) that was picked up using DHCP. I used to do that
same thing when I owned a domain name and I don't remember having any
trouble setting it up

OK. What do you mean, when you say "check that the webserver uses the
right location"?
~
This is what I see when I run lsof
~
sh-3.1# lsof -i -n -P
