Remove simple_httpd
simple_httpd was granted a reprieve from the picobsd removal based on having some reported user; it turns out this user isn't actually using the version in base and merging their changes would be difficult at this point, so the version in base will simply continue to rot. Retire it now, it may make a comeback to ports with the improved version. No notice issued because its current visibility has only been for ~3 months, and a notice has been previously issued about picobsd removal.

Simple_httpd - A small and free Web server
|
||||
|
||||
"Simple_httpd is like /usr/bin/mail is to mail clients, no frills."
|
||||
|
||||
This HTTP server can be used in any FreeBSD/PicoBSD application.
|
||||
|
||||
It has been tested under FreeBSD 2.2.x, 3.x and 4.x. It might work
|
||||
on other OS systems, but it's for FreeBSD primarily.
|
||||
|
||||
The main advantage to Simple_httpd is that it is very small.
|
||||
The 25K binary can satisfy most needs in a small or embedded
|
||||
appplication. If you want a full featured server see
|
||||
/usr/ports/www/apache* or http://www.apache.org
|
||||
|
||||
Simple_httpd is released under a BSD style copyright that unlike
|
||||
GPL is embedded developer friendly.
|
||||
|
||||
The server is designed to be run in one of two modes. The standard
|
||||
mode is a httpd server running in the background serving up a directory
|
||||
of html,gif,cgi whatever. Your traditional www server.
|
||||
|
||||
The "fetch" mode supports file transfer over httpd. This
|
||||
is best thought of as mate for fetch(1). This feature can be
|
||||
useful to transfer a file from one host to another.
|
||||
|
||||
Simple_httpd has the ability to run CGI scripts. All CGI
|
||||
scripts must be located in ${DOCUMENT_ROOT}/cgi-bin. The
|
||||
server currently only sets 3 environment variables before calling
|
||||
the script.
|
||||
|
||||
CGI Environment variables are below:
|
||||
|
||||
SERVER_SOFTWARE = FreeBSD/PicoBSD
|
||||
REMOTE_HOST = client.canada_lower_taxes.com
|
||||
REMOTE_ADDR = 200.122.13.108
|
||||
|
||||
In most target applications for this server the extra DNS traffic from
|
||||
the remote_addr lookup will likely be on the local lan anyway and not
|
||||
on the other side of the internet. You can turn it off yourself in
|
||||
the code if you want to speed the whole process up. Be sure to turn
|
||||
it off for the logfile also.
|
||||
|
||||
How to use it?
|
||||
==============
|
||||
|
||||
Compile with make, run as follows
|
||||
|
||||
usage: simple_httpd [-vD]
|
||||
[-d directory]
|
||||
[-g grpid]
|
||||
[-l logfile]
|
||||
[-p port]
|
||||
or
|
||||
usage: simple_httpd [-p port] -f filename
|
||||
|
||||
-v
|
||||
Run the server verbose. Show the program options that will be used for this
|
||||
process. Will only show information during startup, no messages will
|
||||
be displayed while serving requests. In other words you can still
|
||||
daemonize without fear of output on stdout.
|
||||
|
||||
-D
|
||||
Do not daemonize. The server will not run in the background. It will
|
||||
stay attached to the tty. This is useful for debugging. In this
|
||||
mode no log file is created. Logging info is to stdout.
|
||||
|
||||
This option is automatically selected if fetch option is selected.
|
||||
|
||||
-d directory
|
||||
The html document directory, if nothing is provided the default is
|
||||
/httphome if UID is root, otherwise document root is ${HOME}/public_html
|
||||
|
||||
-l logfile
|
||||
Set the logfile to use. Log messages will be written to /var/log/jhttpd.log
|
||||
if you are root and ${HOME}/jhttpd.log otherwise. If you don't want a
|
||||
log file try "-l /dev/null"
|
||||
|
||||
-p port
|
||||
Set the port httpd server will listen to. Default is port 80 if
|
||||
you are root and 1080 if you are not.
|
||||
|
||||
-f filename
|
||||
This is the only option needed to use the "fetch" feature. The file
|
||||
specified will be the ONLY file served to ANY GET request from a browser
|
||||
or fetch(1).
|
||||
|
||||
Example
|
||||
=======
|
||||
|
||||
Standard Mode:
|
||||
--------------
|
||||
If you have the FreeBSD handbook installed on your machine and would
|
||||
like to serve it up over http for a quick look you could do this
|
||||
|
||||
simple_httpd -d /usr/share/doc/handbook -l /usr/tmp/jlog.txt -p 1088 -v
|
||||
|
||||
Any browser would be able to look at the handbook with
|
||||
http://whatever_host/handbook.html:1088
|
||||
|
||||
I'm using 1088 as the port since I already have apache running on port 80
|
||||
and port 1080 on my host.
|
||||
|
||||
Please note, the handbook is not installed by default in FreeBSD 3.x
|
||||
It must be installed from the ports collection first if you want to
|
||||
try this.
|
||||
|
||||
Another simple example is to browse your local ports collection:
|
||||
|
||||
cd /usr/ports
|
||||
make readmes #wait about 1 hour!
|
||||
simple_httpd -p 1080 -v -d /usr/ports
|
||||
|
||||
Then point your browser at http://whatever_host/README.html
|
||||
|
||||
Fetch Mode:
|
||||
--------------
|
||||
This is designed to be used in conjunction with fetch(3). It allows
|
||||
for easy transfer of files from one host to another without messy
|
||||
authentication or pathnames required with ftp. The file to be
|
||||
served up must be readable by the user running simple_httpd.
|
||||
This is not a magic way to avoid permissions and read files.
|
||||
|
||||
The daemon will only serve up ONE file. The file specified will
|
||||
be returned for every GET request regardless of what the browser
|
||||
asks for. This allows for on the fly naming.
|
||||
|
||||
sender# simple_httpd -f /usr/tmp/big_file.tgz
|
||||
receiver# fetch http://sender.com/Industrial_Secrets.tgz
|
||||
|
||||
big_file.tgz was transferred from one machine to another and renamed
|
||||
Industrial_Secrets.tgz at the same time.
|
||||
|
||||
Tunneling over other TCP ports. Choose something that firewall
|
||||
will probably pass. See /etc/services.
|
||||
|
||||
sender# simple_httpd -p 53 -f /usr/tmp/big_file.tgz
|
||||
receiver# fetch http://sender.com:53/Industrial_Secrets.tgz
|
||||
|
||||
To Do
|
||||
=====
|
||||
|
||||
Simple authentication would be very useful [understatment].
|
||||
/etc/passwd or PAM would be nice.
|
||||
|
||||
I think a netmask option would be good. Most internet appliances
|
||||
probably want to restrict traffic to local ethernet anyway.
|
||||
ie: Allow anything from my class C.
|
||||
|
||||
The server always has 1 zombie process hanging around when it
|
||||
runs as a daemon. Should fix so that it doesn't happen.
|
||||
|
||||
Anything to make it faster!
|
||||
|
||||

|
||||
|
||||
If anyone has any improvements or ways to easily implement something
|
||||
please let me <wlloyd@slap.net> know. If you make some neat embedded
|
||||
device with PicoBSD I want to know too!
