micro_httpd - really small HTTP server
is a very small HTTP server. It runs from inetd, which means
its performance is poor. But for low-traffic sites, it's quite adequate. It
implements all the basic features of an HTTP server, including:
- Security against ".." filename snooping.
- The common MIME types.
- Trailing-slash redirection.
- Directory listings.
All in 150 lines of code.
To install it, add a line like this to /etc/inetd.conf:
micro_http stream tcp nowait nobody /usr/local/sbin/micro_httpd micro_httpd dir
Make sure the path to the executable is correct, and change "dir" to
be the directory you want to serve. Then add a line like this to
micro_http port/tcp #Micro HTTP server
Change "port" to the port number you want to use - 80, 8000, whatever.
Then restart inetd by sending it a "HUP" signal, or rebooting.
On some systems, inetd has a maximum spawn rate - if you try to run inetd
services faster than a certain number of times per minute, it assumed there's
either a bug of an attack going on and it shuts down for a few minutes. If you
run into this problem - look for syslog messages about too-rapid looping -
you'll need to find out how to increase the limit. Unfortunately this varies
from OS to OS. On FreeBSD, you add a "-R 10000" flag to inetd's
initial command line. On some Linux systems, you can set the limit on a
per-service basis in inetd.conf, by changing "nowait" to
Note that you can use micro_httpd to serve HTTPS, if you like, by running it
from stunnel. First fetch and install stunnel - FreeBSD users can just go to
/usr/ports/security/stunnel and do a "make cert ; make install".
Then as root run:
stunnel -p /usr/local/certs/stunnel.pem -d 443 -l /usr/local/sbin/micro_httpd -- micro_httpd dir
Make sure the paths to the certificate and executable are correct, and again
don't forget to change "dir" to the directory you want to serve.
