micro-httpd - really small HTTP server
30
micro-httpd is a very small HTTP server all in 150 lines of code. It
31
runs from inetd, which means its performance is poor. But for
32
low-traffic sites, it is quite adequate. It implements all the basic
33
features of an HTTP server, including:
35
* Security against ".." filename snooping.
36
* The common MIME types.
37
* Trailing-slash redirection.
41
To install it, add a line like this to /etc/inetd.conf:
43
micro-http stream tcp nowait nobody \
44
/usr/sbin/micro-httpd micro-httpd dir
46
Make sure the path to the executable is correct, and change "dir" to
47
be the directory you want to serve. You could add line like this to
50
micro-http port/tcp #Micro HTTP server
52
Change "port" to the port number you want to use: 80, 8000, whatever.
53
Restart inetd by sending it a "HUP" signal.
55
On some systems, inetd has a maximum spawn rate - if you try to run
56
inetd services faster than a certain number of times per minute, it
57
assumed there is either a bug of an attack going on and it shuts down
58
for a few minutes. If you run into this problem - look for syslog
59
messages about too-rapid looping - you will need to find out how to
60
increase the limit. Unfortunately this varies from OS to OS. On
61
FreeBSD, you add a "-R 10000" flag to inetd's initial command line. On
62
some Linux systems, you can set the limit on a per-service basis in
63
inetd.conf, by changing "nowait" to "nowait.10000".
65
Note that you can use micro-httpd to serve HTTPS, if you like, by
66
running it from stunnel. First fetch and install stunnel - FreeBSD
67
users can just go to /usr/ports/security/stunnel and do a "make cert ;
68
make install". Then as root run:
70
stunnel -p /usr/local/certs/stunnel.pem -d 443 -l \
71
/usr/sbin/micro-httpd -- micro-httpd dir
73
Make sure the paths to the certificate and executable are correct, and
74
again don not forget to change "dir" to the directory you want to
