Hi,
I want to create a simple web application in Embedded Linux.
I downloaded thttpd from www.acme.com
I am not sure to create a simple application.
If there is any website which says steps for creating simple
webserver application for embedded linux suggest me.
Suggest me steps to create simple webserver application for ARM.

Regards,
Kirthika

Hi,
Eh, server.. i don't have idea.

Pls suggest me website for just going through this.

httpd is client side

WebServer based application only we are doing.
I have to do with thttpd only.
I just want to know the steps for building html pages using thttpd
webserver.

I searched in web. I didn't get any solid idea.

Suggest me steps for building html pages or web page using thttpd
server.

Regards,
Kirthika.

Busybox has a httpd client.
You already have busybox IIRC, reconfigure with httpd enabled.

Use text editior, download html specs, write webpage.

Indoin gso you must have looked at _hundreds_ of html pages, use show source in browser.

I give up, India is not going to make it in IT, no matter how cheap they work.

No, httpd is a server program. If it's in your embedded box, your box is
also a server.

Html pages are plain text files, just write them with your favorite text
editor, place them somewhere on the filesystem and tell the location to
thttpd with the -d option.

Dear Kirthika ,

I think it will be better if you try the buildroot for your
development (http://buildroot.uclibc.org/). The buildroot already
contains almost all type of servers such as web , ftp, etc.

Hi,
I am working with Webserver application development.
I ported webserver to my target device which is thttpd(i
downloaded from
www.acme.com). thttpd is my server.

I created a simple html page and i put in root file system of
target device.

I want to view my html page in my PC if i give <board ip
address :port>
I am not getting the page.

I am not sure to link my html page with thttpd and to make it run
in PC
once i give IP address of target device.

If i give thttpd -d <test.html>
Its not showing the web page in PC.
How to make my web page which in target system to view in my PC once
i give IP address of target device in PC side.

Pls. suggest me.

Regards,
Kirthika

Hi Karthika,

I think you are not sure what you want and what you are trying to do.
so I suggest first you should decide yourself what exactly you want to
do.

Anyways let me just understand the problem. Is it like you have a box
and you want to access it through HTTP from some other PC? Or you want
to write an HTTP server for embedded Linux box? You need two things
first HTTP server which will be running on box and browser running on
PC. First make sure that your box is listening on port 80 (default)
using netstat. if it is not running you should whether your box has
HTTPD in it and find a way to run it. You can download httpd
application from Internet. Once box is listening for HTTP connection,
you can connect it from any machine.

Hi,
ping is working in both sides
But if i give
telnet <ipaddress of PC>, portno in target board side
and if i view the output with Etheral analyser i was able to see the
following response
board sending request , PC sending acknowledgement.

But
telnet <ipaddress of target board> , portno in PC side
PC keeps on sending request.
No acknowledgement from device to PC.

Ping is working in PC side as well as target board side.

Suggest me in resolving this problem...

Further i was not able to see the html page in my PC side when i give
http://board ip address/test.html

Regards,
Kirthika

Many reasons possible. Can you ping the board? Does the httpd responds to

$ telnet IP-ADDRESS 80

from your developers machine?

>

This is clearly wrong. Suggesting you put a file /htdocs/test.html on your
embedded machine, it must read "thttpd -d /htdocs"

You then may check with the browser on your developers machine by typing

http://IP-ADDRESS/test.html

Kind regards

You should check "iptables -nvL" on the embedded board. Some firewall
setting may keep incoming TCP requests outside.

Hi,
I have a small doubt.
I don't have http or httpd in my target device.
In my target device whether i need http or httpd to make telnet
<board ip
address>, portno. to work from PC side.

I have telnet in my target device.

I know i am asking very basic question...

IP tables i am checking. I was able to find Kernel Route tables only..

Regards,
Kirthika

I don't believe busybox (upto 1.6 or so) supports iptables.
Also, iptables tends to need a strong tie in to the kernel, in that a new
netfilter modules needs explicit support in the iptables command.

Usually, one cross-compiles iptables from it's native sources and adds the
result to the rootfs.

Well, you need httpd on your target device to get it responing to http
requests. What did you expect?

(I thought it was working with locaho connection -- this was on your
developers machine, right?)

httpd.

You won't need a telnet or http (any browser) client, but only httpd, a http
server.

Y-E-S. This is sometimes confusing even to others.

Chances are you even have no iptables support in your target system kernel.
Just forget about it for now.

I think you have to put your HTML files in /usr/local/www/data
directory. By default your server will look for files in this
directory only. So try putting files in this directory if you have one
already or create new one. By the way, you can change this path to
some other in your configuration file (/usr/local/www/thttpd_config).

Hi,
I have thttpd as webserver in target device.
So no problem. My confusion is cleared regarding http and thttpd.

After creating a web page which in put in root file system of target
device (In root
file system i kept in usr/local/www/mywebpage.html or /www/
mywebpage.html
After loading my ramdisk or root file system to target device i gave
thttpd -d /usr/local/www/ -c "*"
And when i view the current process using ps command its showing my
process
thttpd -d /usr/local/www -c "*"

I am not sure whether the binding of application with thtttp is
correct or not.
The above command only i used for binding.

But somewhere the link between PC and target side thttpd is missing.
Thats why target side is not responding to my PC request.

After loading thttpd (which i downloaded from www.acme.com) to target
device whether any configuration i have to do for adding my
application other than binding with the above command.

How to find out the fire wall in target side?

Further i have another query. "www.acme.com" has default web page
"index.html
That should run know..(default)

telnet <board ip address, port no> is not working yet when i send
request from PC side.
How to find out where the problem is.

Even i kept some simple web page in usr/local/www of target side.

That also is not working.

Help me in resolving..

Regards
Kirthika
