When you need a web server in a hurry.

Features:

• Simple to set up:
  • Single binary, no other files, no installation needed.
  • Standalone, doesn't need inetd or ucspi-tcp.
  • No messing around with config files - all you have to specify is the www root.
• Written in C - efficient and portable.
• Small memory footprint.
• Event loop, single threaded - no fork() or pthreads.
• Generates directory listings.
• Supports HTTP GET and HEAD requests.
• Supports Range / partial content. (try streaming music files or resuming a download)
• Supports If-Modified-Since.
• Supports Keep-Alive connections.
• Supports IPv6.
• Support arbitrary custom response headers.
• Can serve 301 redirects based on Host header.
• Uses sendfile() on FreeBSD, Solaris and Linux.
• Can use acceptfilter on FreeBSD.
• Can use chroot as non-root on FreeBSD 14+.
• At some point worked on FreeBSD, Linux, OpenBSD, Solaris.
• ISC license.
• suckless.org says darkhttpd sucks less.
• Small Docker image (<100KB)

Security:

• Can log accesses, including Referer and User-Agent.
• Can chroot.
• Can drop privileges.
• Impervious to /../ sniffing.
• Times out idle connections.
• Drops overly long requests.

Limitations:

• Only serves static content - no CGI.

Simply run make:

make

If cc is not on your PATH as an alias to your C compiler, you may need to specify it. For example,

CC=gcc make

Serve /var/www/htdocs on the default port (80 if running as root, else 8080):

./darkhttpd /var/www/htdocs

Serve ~/public_html on port 8081:

./darkhttpd ~/public_html --port 8081

Only bind to one IP address (useful on multi-homed systems):

./darkhttpd ~/public_html --addr 192.168.0.1

Serve at most 4 simultaneous connections:

./darkhttpd ~/public_html --maxconn 4

Log accesses to a file:

./darkhttpd ~/public_html --log access.log

Chroot for extra security (you need root privs for chroot):

./darkhttpd /var/www/htdocs --chroot

Use default.htm instead of index.html:

./darkhttpd /var/www/htdocs --index default.htm

Add mimetypes - in this case, serve .dat files as text/plain:

$ cat extramime
text/plain  dat
$ ./darkhttpd /var/www/htdocs --mimetypes extramime

Drop privileges:

./darkhttpd /var/www/htdocs --uid www --gid www

Use acceptfilter (FreeBSD only):

kldload accf_http
./darkhttpd /var/www/htdocs --accf

Run in the background and create a pidfile:

./darkhttpd /var/www/htdocs --pidfile /var/run/httpd.pid --daemon

Serve only one file instead of a whole directory:

./darkhttpd ~/public_html/index.html --single-file

Web forward (301) requests for some hosts:

./darkhttpd /var/www/htdocs --forward example.com http://www.example.com \
  --forward secure.example.com https://www.example.com/secure

Web forward (301) requests for all hosts:

./darkhttpd /var/www/htdocs --forward example.com http://www.example.com \
  --forward-all http://catchall.example.com

Arbitrary custom response headers (in this case, allow all cross-origin requests):

./darkhttpd /var/www/htdocs --header 'Access-Control-Allow-Origin: *'

Commandline options can be combined:

./darkhttpd ~/public_html --port 8080 --addr 127.0.0.1

To see a full list of commandline options, run darkhttpd without any arguments:

./darkhttpd

First, build the image.

docker build -t darkhttpd .

Then run using volumes for the served files and port mapping for access.

For example, the following would serve files from the current user's dev/mywebsite directory on http://localhost:8080/

docker run -p 8080:80 -v ~/dev/mywebsite:/var/www/htdocs:ro darkhttpd

Enjoy.

make test

If that isn't working for you, and you're on FreeBSD, you may need to run something closer to the following:

ASAN_OPTIONS=" " PYTHON=python3.11 make test
