HTTP info server
HTTP info server is the 1st project to subject IPK (Computer Communications and Networks). It provides a script that acts as an HTTP server informing about the system where it is running.
Compilation
Installation of this project could be done by using the Make program. The default rule from the packed Makefile does this job. You can compile the whole script with:
make
The compilation phase will produce one binary file called hinfosvc, a few obj files, and a dep.list. You can run Make again for removing temporarily created files: make clean.
Running the script
This project has only one executable binary file - hinfosvc. It starts the HTTP server providing information about the machine where the script is running. To run the script, use this command structure:
./hinfosvc PORT &
For example: ./hinfosvc 1221 runs the server on port 1221. The server will be available at all IP (v4 and v6) addresses of the machine. For testing, you can use http://localhost:1221 with the address of the wanted information (see next section).
Usage
There are three types of information the server provides. You can find them in the following subsections.
Hostname
The first information you can get from the server is the fully qualified hostname of the computer.
GET http://server-name:PORT/hostname
Example request (from internet browser):
http://localhost:1221/hostname
Example output (text/plain):
On personal computer (not in a domain):
xsmahe01-notebook
On school/enterprise machine (in a domain):
minerva3.fit.vutbr.cz
CPU name
The second information you can get is the name of the used CPU.
GET http://server-name:PORT/cpu-name
Example request (from internet browser):
http://localhost:1221/cpu-name
Example output (text/plain):
Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz
CPU load
The last information provided by the HTTP server is the CPU load. It is the average usage of the CPU (across its cores).
GET http://server-name:PORT/load
Example request (from internet browser):
http://localhost:1221/load
Example output (text/plain):
