A simple CGI webserver written in C with no dependencies.

A Simple CGI Server

This is a small CGI server written in C. It has no dependencies outside of the provided files, assuming a POSIX-compatible operating environment.

By default, the server will try to run on port 80. You can supply a different port number as an argument, or edit the source to change the default port.

The server will serve files out of the pages directory, but you can change this as well by editing the source.

cgiserver's Issues

Failed to bind socket to port 80!

Other ports (like 8080) work ok.

output of sudo lsof -i:80 is empty. What can I do?

Don’t allow going outside PAGES_DIRECTORY

The server as it stands now will happily display things like /../, /../../, or ../../../../../../../../../../etc/passwd. (Note that most modern browsers and even curl will refuse to make such requests, but, say, HTTPie won’t, and there’s always telnet.) Such requests should be treated as if PAGES_DIRECTORY is the filesystem root.

In use

Hi!
I would like to congratulate you on the project. I needed something simple and functional to add some functionality in a small project, your code answered perfectly.

CGI not working

Hi Klange,

Thank you for put the cgiserver online. I compiled today on my Linux box, run cgiserver. The server runs on my localhost but it wont parse .php file, it spew out the script. Is it possible to add path to php interpreter instead of on pipe or socket?
That way we can use it for any cgi executable and make it more flexible and more generic.

Many thanks!

Hear from you soon!

God blesses!!!

Best regards,
