In my project I have to run a unix commond from html page to change my IP address of my target board.
can some one suggest me how to achieve this.

you need three things for that:
1. HTTP server with CGI support
2. a privileged daemon that can change IP-address (it can listen for commands on a socket or with named pipe or whatever you prefer)
3. CGI script that sends appropriate command to the daemon

I have a commond "fw_setenv ipaddr 'ip'", this commond on target terminal will change the ip address in u-boot environment. when next time the target restarted will come up with same ip address which as in u-boot environment.

this is happing through terminal, but I want this need happen on onclick submit in HTML page.

In HTML page I will be mentioniong the Ip address and followed by submit,my fw_setenv ipaddr commond as to take ip address from HTML and execute.

I have HTML server with CGI support, please guide me how can i achieve the above with giving som example code.

does fw_setenv have SUID (check with «stat» command)? if not, you still need a privileged daemon to run «fw_setenv»

yeah its having, I want to know how should i call the fw_setenv to execute onclick in html.

where should i call that commond to execute in .cgi or .htm file and how can i call that..??

just look at any CGI example for your preferable language
