micro_httpd is a very small HTTP server.
It runs from inetd, which means its performance is poor.
But for low-traffic sites, its quite adequate.
It implements all the basic features of an HTTP server, including:
All in 150 lines of code.
Security against ".." filename snooping.
The common MIME types.
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 /etc/services:
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 theres 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 - youll 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 inetds initial command line.
On some Linux systems, you can set the limit on a per-service basis
in inetd.conf, by changing "nowait" to "nowait.10000".
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 --
Make sure the paths to the certificate and executable are correct, and
again dont forget to change "dir" to the directory you want to serve.
