This is a open source light weight web server to implement HTTP/1.1, easy to setup with minimum effort to get it running.
Download a copy of thttpd to unzip.
Configure and compile it.
./configure --host=arm-linux
make
Note, if there is a conflicting getline error in extras/htpasswd.c change all the getline function to some other name eg. getlines to make it unique.
Copy the thttpd executable file to /rootfs/usr/sbin (this is assume the root filesystem is created in /rootfs directory).
cp thttpd /rootfs/usr/sbin
Create a thttpd.config file in the /rootfs/etc directory for its configuration settings.
dir=/www
user=root
cgipat=/cgi-bin/*
logfile=/tmp/thttpd.log
pidfile=/var/thttpd.pid
Add the command line to the rcS script to start up the http server.
# start HTTP server
thttpd -C /etc/thttpd.config
Create a directory for the web page.
mkdir -p /rootfs/www/cgi-bin
Create a simple index.html program in the www directory.
<html>
<head>
<title>Welcome html</title>
</head>
<body>
<h1>Hello World!</h1>
</body>
</html>
Restart the board, go to the host computer web browser and enter the url of the device ip address eg. http://192.168.114.190/index.html
Note, the board must be configured with network address over the NFS service.
Image may be NSFW.
Clik here to view.
However, to make our target board as a client we have to configure our host as a router which allow network traffic to be redirected to access the internet gateway, this set up assume the target and host is connected via a hub with NFS service.
First create a virtual network interface, this interface is use as a bridge to our target as a logical subnet.
ifconfig eth0:1 192.168.114.254 netmask 255.255.255.0 up
then, configure the interface routing and enable IP Forward function below.
iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
iptables --append FORWARD --in-interface eth0 -j ACCEPT
echo "1">/proc/sys/net/ipv4/ip_forward
next, in the target bootloader environment, change serverip and gateway reference to eth0:1 IP address (eg. as above 192.168.114.254) and update the bootargs.
That's it, reboot target and it should be able to access to the internet.
