Is anyone interested in my crude hackery which allows you to serve web pages on your zaurus without installing any software? I'll assume so!
At the end of the day, a web server can be written in a shell script, with the networking provided by inetd, so provided you generate the right http response headers it's actually quite trivial! I've used this for quite a few years and not come across anyone else doing it, and it seems to me that the Z is an ideal target for something so light weight. Add the following line to the bottom of your /etc/inetd.conf file: CODE http stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/sh-httpd don't worry about the spacing. Then you need to HUP inetd process, by entering the command "ps -ef | grep inet", look for the first number and enter "kill -1 xxxx". Or, in desperation, reboot! e.g. CODE # ps -ef | grep inet root 4802 1 0 21:41 ? 00:00:00 /usr/sbin/inetd root 5726 5671 0 22:41 pts/0 00:00:00 grep inet # kill -1 4802 # Then create the following script, as /usr/local/bin/sh-httpd: CODE #!/bin/bash DBGFILE=/tmp/sh-httpd.log date >> $DBGFILE H="IGNORE" while [ "$H" != "" ]; do echo $H >> $DBGFILE read H H=`echo $H | sed -e 's/^M//g'` done echo 'HTTP/1.1 200 OK' echo -n "Date: "' date|sed 's/ /, /'' echo 'Server: sh-http/0.01 (Linux/bash)' echo 'Accept-Ranges: bytes' echo 'Connection: close' echo 'Content-Type: text/html' echo '' echo '<?xml version="1.0" encoding="ISO-8859-1"?>' echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">' echo '<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">' echo '<head><title>Zaurus sh-httpd daemon</title></head>' echo '<body bgcolor="#ffffff">' echo "<p>" echo "<b>hello</b>" echo "</p>" echo "</html>" echo "finished" >> $DBGFILE # end sh-httpd A key part in the script is that you see ^M in the while loop, but it's actually a ctrl-m, which you get in vi by typing ctrl-v ctrl-m. Or, attached is the script; I had to add a .txt type to make it uploadable. Once created, make it executable using CODE chmod ugo+x /usr/local/bin/sh-httpd Then test it, either from the local browser using "http://127.0.0.1" or remotely when usb networking is up (http://192.168.129.201) or over wifi. Note that if you've use iptables firewalling on your Z you need to punch a hole for port 80, e.g. "iptables -I INPUT -p tcp --dport 80 -j ACCEPT". BTW, I am doing this now because I want to write a somewhat more sophisticated version in order to produce some local management tools for the Z which aren't present in the normal ROM, and also for a small secret project which will be revealed soon  -- edited quite a few times to ensure layout and clarity is up to standard!
