Ltsp WebUsing tserver as a client Web Server
Why would you do this.
Web Servers allow access to the host using a simple web browser. A web server that can be CGI scripted be used to create custom applications using forms.Tserver
Tserver was written by Andrew Tridgell of Samba fame and is part of his junk code collection. It's claim to fame is the ability to execute bash commands as embedded CGI in an extermely light weigth server program with few library dependencies.
# ls -l /usr/sbin/tserver
-rwxr-xr-x 1 root root 14552 Mar 26 16:30 tserver
# ldd /usr/sbin/tserver
libc.so.6 => /lib/libc.so.6 (0x40018000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
A web page like thus:
<HTML>
<BODY>
<H1>Welcome to LTSP Client <font color=red> {{ ! hostname }} </font> </H1>
Here is the contents of some interesting /proc files
<pre>
<h4>/proc/cpuinfo</h4>
{{ !
cat /proc/cpuinfo
}}
<h4>/proc/meminfo</h4>
{{!
cat /proc/meminfo
}}
</pre>
</BODY>
</HTML>
will output a Web page with the hostname of the machine substituted. The syntax {{ ! bash script commands }} execute the external command and substitute its output for the {{ ...... }}. Attached is an example page from the distribution files.
