=head1 NAME
micro-httpd - really small HTTP server
=head1 SYNOPSIS
micro-httpd DIRECTORY
=head1 OPTIONS
None.
=head1 DESCRIPTION
micro-httpd is a very small HTTP server all in 150 lines of code. It
runs from inetd, which means its performance is poor. But for
low-traffic sites, it is quite adequate. It implements all the basic
features of an HTTP server, including:
* Security against ".." filename snooping.
* The common MIME types.
* Trailing-slash redirection.
* index.html
* Directory listings.
To install it, add a line like this to /etc/inetd.conf:
micro-http stream tcp nowait nobody \
/usr/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. You could add 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.
Restart inetd by sending it a "HUP" signal.
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 is 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 will 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 "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/sbin/micro-httpd -- micro-httpd dir
Make sure the paths to the certificate and executable are correct, and
again don not forget to change "dir" to the directory you want to
serve.
