To build:
% ./configure
Edit config.h to change the configuration options if necessary.
% make
To install:
% make install
Edit one of your system rc files to run thttpd at boot time. Do NOT
run it from inetd, that setup is inefficient so thttpd doesn't support it.
Red Hat:
On Red Hat Linux systems you can use RPM to install thttpd, like so:
cd /usr/src/redhat/SOURCES
wget http://www.acme.com/software/thttpd/thttpd-2.29.tar.gz
rpm -ta thttpd-2.29.tar.gz
rpm -i /usr/src/redhat/RPMS/i386/thttpd-2.29-1.i386.rpm
Solaris:
If you're running Solaris and you want to use the security-enhancing
chroot feature, then you must create the TCP device files in the chroot
tree. There is no way around this, Solaris needs these files to accept
network connections. You need /dev/tcp, which is a symbolic link like so:
/dev/tcp -> ../devices/pseudo/clone@0:tcp
And you also need the file it points to:
crw-rw-rw- bin 11, 42 May 24 21:32 /devices/pseudo/clone@0:tcp
You probably need some other files too, such as shared libraries and
a tmp directory. Check out the man page for ftpd, it has a big long
shell script for setting up an anonymous ftp area that should also
work for thttpd.

thttpd - tiny/turbo/throttling HTTP server
version 2.29 of 23May2018
thttpd is a simple, small, portable, fast, and secure HTTP server.
Simple: It handles only the minimum necessary to implement HTTP/1.1.
Small: See the size comparison chart at
http://www.acme.com/software/thttpd/notes.html#sizes. It also has a
very small run-time size, since it does not fork and is very careful about
memory allocation.
Portable: It compiles cleanly on FreeBSD 2.x/3.x, SunOS 4.1.x, Solaris 2.x,
BSD/OS 2.x, Linux 1.2.x, OSF/1 (on a 64-bit Alpha), and no doubt many others.
Fast: In typical use it's about as fast as the best full-featured servers
(Apache, NCSA, Netscape). Under extreme load it's much faster.
Secure: It goes to great lengths to protect the web server machine
against attacks and breakins from other sites.
It also has one extremely useful feature (URL-traffic-based throttling) that
no other server currently has.
See the manual entry for more details. See the INSTALL file for
configuration and installation instructions. Check the web page
(http://www.acme.com/software/thttpd/) for updates, or add yourself to
the mailing list by sending a "subscribe" to thttpd-announce-request@mail.acme.com.

dnl
dnl This test is for network applications that need socket() and
dnl gethostbyname() -ish functions. Under Solaris, those applications
dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
dnl with "-lnsl" but should *not* link with "-lsocket" because
dnl libsocket.a breaks a number of things (for instance:
dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
dnl versions of IRIX).
dnl
dnl Unfortunately, many application developers are not aware of this,
dnl and mistakenly write tests that cause -lsocket to be used under
dnl IRIX. It is also easy to write tests that cause -lnsl to be used
dnl under operating systems where neither are necessary (or useful),
dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
dnl
dnl This test exists so that every application developer does not test
dnl this in a different, and subtly broken fashion.
dnl It has been argued that this test should be broken up into two
dnl seperate tests, one for the resolver libraries, and one for the
dnl libraries necessary for using Sockets API. Unfortunately, the two
dnl are carefully intertwined and allowing the autoconf user to use
dnl them independantly potentially results in unfortunate ordering
dnl dependancies -- as such, such component macros would have to
dnl carefully use indirection and be aware if the other components were
dnl executed. Since other autoconf macros do not go to this trouble,
dnl and almost no applications use sockets without the resolver, this
dnl complexity has not been implemented.
dnl
dnl The check for libresolv is in case you are attempting to link
dnl statically and happen to have a libresolv.a lying around (and no
dnl libnsl.a).

/* phf - cracker trap
**
** Old distributions of the NCSA and Apache web servers included a
** version of the phf program that had a bug. The program could
** easily be made to run arbitrary shell commands. There is no real
** legitimate use for phf, so any attempts to run it must be considered
** to be attacks. Accordingly, this version of phf logs the attack
** and then returns a page indicating that phf doesn't exist.

.TH redirect 8 "23 September 1995"
.SH NAME
redirect - simple redirection CGI program
.SH SYNOPSIS
.B redirect
.SH DESCRIPTION
.PP
Three steps to set up a redirection:
.PP
1. Make sure your web server is set up to allow CGI programs.
.PP
2. Make a symbolic link from the file or directory you want to redirect,
pointing at this program in the CGI bin directory.
.PP
3. Add an entry to the file ".redirects" in the directory where your
http server runs CGI programs. For most servers, this is the
directory where the given CGI program lives. The format of the
file is a bunch of lines with a filename, whitespace, and the new
URL. For example:
.nf
/test/oldfile.html http://www.acme.com/test/newfile.html
.fi
The easiest way to figure out precisely what filename to put into .redirects
is to set up the symlink and then click on it.
You'll get back a "404 Not Found" page which includes the filename
as received by the redirect program, and that's what you want to use.
.PP
You can also add a wildcard specification to redirect whole groups of files.
For example:
.nf
/wildtest/* http://www.acme.com/test-
.fi
will cause an access to the /wildtest/somefile.html to be redirected to
http://www.acme.com/test-somefile.html. (Note that the asterisk need not
be preceded by a slash.)
.PP
Note: this is designed for thttpd (http://www.acme.com/software/thttpd/)
and using it with other web servers may require some hacking. A possible
gotcha is with the symbolic link from the old file pointing at this
script - servers other than thttpd may not allow that link to be run
as a CGI program, because they don't check the link to see that it
points into the allowed CGI directory.
.SH "SEE ALSO"
thttpd(8)
.SH "BUGS / DEFICIENCIES"
.PP
It would be really cool to have this program look for
the .redirects file in the same directory as the file being redirected,
instead of in the binaries directory. Unfortunately, this appears
to be impossible with the information CGI gives, plus the non-standardized
but widespread practice of running CGI programs in the directory where
the binary lives. Perhaps CGI 1.2 will address this.
.PP
The wildcard mechanism is very primitive.
In particular, any characters that follow the asterisk are blithely
ignored.

.TH ssi 8 "18 October 1995"
.SH NAME
ssi - server-side-includes CGI program
.SH SYNOPSIS
.B ssi
.SH DESCRIPTION
.PP
This is an external CGI program that gives you the same functionality
as the built-in server-side-includes feature in some HTTP daemons.
It is written for use with thttpd(8), but should be easy to adapt
to other systems.
.PP
To use this program, first make sure it is installed in your server's
CGI area, and that CGI is enabled.
Then set up your URLs with the path to the document you want parsed
as the "pathinfo".
That's the part of the URL that comes after the CGI program name.
For example, if the URL to this program is:
.nf
http://www.acme.com/cgi-bin/ssi
.fi
and the url for your document is:
.nf
http://www.acme.com/users/wecoyote/doc.html
.fi
then the compound URL that gives you the document filtered through the
program would be:
.nf
http://www.acme.com/cgi-bin/ssi/users/wecoyote/doc.html
.fi
.PP
The format description below is adapted from
http://hoohoo.ncsa.uiuc.edu/docs/tutorials/includes.html
.SH "INCLUDE FORMAT"
.PP
All directives are formatted as SGML comments within the document.
This is in case the document should ever find itself in the client's
hands unparsed.
Each directive has the following format:
.nf
<!--#command tag1="value1" tag2="value2" -->
.fi
Each command takes different arguments, most only accept one tag at a time.
Here is a breakdown of the commands and their associated tags:
.IP * 4
.BR config :
The config directive controls various aspects of the file parsing.
There are two valid tags:
.IP o 8
.BR timefmt :
gives the server a new format to use when providing dates.
This is a string compatible with the strftime library call.
.IP o 8
.BR sizefmt :
determines the formatting to be used when displaying the
size of a file.
Valid choices are bytes, for a formatted byte count
(formatted as 1,234,567), or abbrev for an abbreviated version
displaying the number of kilobytes or megabytes the file occupies.
.IP * 4
.BR include :
Inserts the text of another document into the parsed document.
The inserted file is parsed recursively, so it can contain
server-side-include directives too.
This command accepts two tags:
.IP o 8
.BR virtual :
Gives a virtual path to a document on the server.
.IP o 8
.BR file :
Gives a pathname relative to the current directory. ../ cannot
be used in this pathname, nor can absolute paths be used.
.IP * 4
.BR echo :
Prints the value of one of the include variables (defined below).
Any dates are printed subject to the currently configured timefmt.
The only valid tag to this command is var, whose value is the name of the
variable you wish to echo.
.IP * 4
.BR fsize :
prints the size of the specified file,
subject to the sizefmt parameter to the config command.
Valid tags are the same as with the include command.
.IP * 4
.BR flastmod :
prints the last modification date of the specified file, subject
to the formatting preference given by the timefmt parameter to config.
Valid tags are the same as with the include command.
.SH VARIABLES
.PP
A number of variables are made available to parsed documents.
In addition to
the CGI variable set, the following variables are made available:
.IP * 4
.BR DOCUMENT_NAME :
The current filename.
.IP * 4
.BR DOCUMENT_URI :
The virtual path to this document (such as /~robm/foo.shtml).
.IP * 4
.BR QUERY_STRING_UNESCAPED :
The unescaped version of any search query the client sent.
.IP * 4
.BR DATE_LOCAL :
The current date, local time zone.
Subject to the timefmt parameter to the config command.
.IP * 4
.BR DATE_GMT :
Same as DATE_LOCAL but in Greenwich mean time.
.IP * 4
.BR LAST_MODIFIED :
The last modification date of the current document.
Subject to timefmt like the others.
.SH "BUGS / DEFICIENCIES"
.PP
Does not implement the "exec" directive.
Actually, I consider this neither a bug nor a deficiency, but some may.

Summary: Throttleable lightweight httpd server
Name: thttpd
Version: 2.29
Release: 1
Group: Networking
URL: http://www.acme.com/software/thttpd
Source0: http://www.acme.com/software/thttpd/thttpd-%{PACKAGE_VERSION}.tar.gz
Copyright: distributable (BSD)
BuildRoot: /tmp/thttpd-root
%description
Thttpd is a very compact no-frills httpd serving daemon that can handle
very high loads. While lacking many of the advanced features of
Apachee, thttpd operates without forking and is extremely efficient in
memory use. Basic support for cgi scripts, authentication, and ssi is
provided for. Advanced features include the ability to throttle traffic.

.TH syslogtocern 8 "12 October 1995"
.SH NAME
syslogtocern - convert thttpd syslog entries into CERN Common Log format
.SH SYNOPSIS
.B syslogtocern
.I logfile
.RI ...
.SH DESCRIPTION
.PP
Reads one or more syslog files as input.
Takes the thttpd entries, and converts them into CERN Combined Common
Log format.
Produces two files as output: access_log and error_log.
If files with those names already exist in the current directory, they
are overwritten.
.SH "SEE ALSO"
thttpd(8)
.SH "BUGS / DEFICIENCIES"
Lumps all thttpd processes together.
It ought to produce separate files for each, identified by IP address and
port number.
However, that change represents a huge increase in complexity, so next version.

/* fdwatch.h - header file for fdwatch package
**
** This package abstracts the use of the select()/poll()/kqueue()
** system calls. The basic function of these calls is to watch a set
** of file descriptors for activity. select() originated in the BSD world,
** while poll() came from SysV land, and their interfaces are somewhat
** different. fdwatch lets you write your code to a single interface,
** with the portability differences hidden inside the package.
**
** Usage is fairly simple. Call fdwatch_get_nfiles() to initialize
** the package and find out how many fine descriptors are available.
** Then each time through your main loop, call fdwatch_clear(), then
** fdwatch_add_fd() for each of the descriptors you want to watch,
** then call fdwatch() to actually perform the watch. After it returns
** you can check which descriptors are ready via fdwatch_check_fd().
**
** If your descriptor set hasn't changed from the last time through
** the loop, you can skip calling fdwatch_clear() and fdwatch_add_fd()
** to save a little CPU time.

.SH DESCRIPTION
.PP
.I thttpd
is a simple, small, fast, and secure HTTP server.
It doesn't have a lot of special features, but it suffices for most uses of
the web, it's about as fast as the best full-featured servers (Apache, NCSA,
Netscape),
and it has one extremely useful feature (URL-traffic-based throttling)
that no other server currently has.
.SH OPTIONS
.TP
.B -C
Specifies a config-file to read.
All options can be set either by command-line flags or in the config file.
See below for details.
.TP
.B -p
Specifies an alternate port number to listen on.
The default is 80.
The config-file option name for this flag is "port",
and the config.h option is DEFAULT_PORT.
.TP
.B -d
Specifies a directory to chdir() to at startup.
This is merely a convenience - you could just as easily
do a cd in the shell script that invokes the program.
The config-file option name for this flag is "dir",
and the config.h options are WEBDIR, USE_USER_DIR.
.TP
.B -r
Do a chroot() at initialization time, restricting file access
to the program's current directory.
If -r is the compiled-in default, then -nor disables it.
See below for details.
The config-file option names for this flag are "chroot" and "nochroot",
and the config.h option is ALWAYS_CHROOT.
.TP
.B -dd
Specifies a directory to chdir() to after chrooting.
If you're not chrooting, you might as well do a single chdir() with
the -d flag.
If you are chrooting, this lets you put the web files in a subdirectory
of the chroot tree, instead of in the top level mixed in with the
chroot files.
The config-file option name for this flag is "data_dir".
.TP
.B -nos
Don't do explicit symbolic link checking.
Normally, thttpd explicitly expands any symbolic links in filenames,
to check that the resulting path stays within the original document tree.
If you want to turn off this check and save some CPU time, you can use
the -nos flag, however this is not recommended.
Note, though, that if you are using the chroot option, the symlink
checking is unnecessary and is turned off, so the safe way to save
those CPU cycles is to use chroot.
The config-file option names for this flag are "symlinkcheck" and "nosymlinkcheck".
.TP
.B -v
Do el-cheapo virtual hosting.
If -v is the compiled-in default, then -nov disables it.
See below for details.
The config-file option names for this flag are "vhost" and "novhost",
and the config.h option is ALWAYS_VHOST.
.TP
.B -g
Use a global passwd file.
This means that every file in the entire document tree is protected by
the single .htpasswd file at the top of the tree.
Otherwise the semantics of the .htpasswd file are the same.
If this option is set but there is no .htpasswd file in
the top-level directory, then thttpd proceeds as if the option was
not set - first looking for a local .htpasswd file, and if that doesn't
exist either then serving the file without any password.
If -g is the compiled-in default, then -nog disables it.
The config-file option names for this flag are "globalpasswd" and
"noglobalpasswd",
and the config.h option is ALWAYS_GLOBAL_PASSWD.
.TP
.B -u
Specifies what user to switch to after initialization when started as root.
The default is "nobody".
The config-file option name for this flag is "user",
and the config.h option is DEFAULT_USER.
.TP
.B -c
Specifies a wildcard pattern for CGI programs, for instance "**.cgi"
or "/cgi-bin/*".
See below for details.
The config-file option name for this flag is "cgipat",
and the config.h option is CGI_PATTERN.
.TP
.B -t
Specifies a file of throttle settings.
See below for details.
The config-file option name for this flag is "throttles".
.TP
.B -h
Specifies a hostname to bind to, for multihoming.
The default is to bind to all hostnames supported on the local machine.
See below for details.
The config-file option name for this flag is "host",
and the config.h option is SERVER_NAME.
.TP
.B -l
Specifies a file for logging.
If no -l argument is specified, thttpd logs via syslog().
If "-l /dev/null" is specified, thttpd doesn't log at all.
The config-file option name for this flag is "logfile".
.TP
.B -i
Specifies a file to write the process-id to.
If no file is specified, no process-id is written.
You can use this file to send signals to thttpd.
See below for details.
The config-file option name for this flag is "pidfile".
.TP
.B -T
Specifies the character set to use with text MIME types.
The default is UTF-8.
The config-file option name for this flag is "charset",
and the config.h option is DEFAULT_CHARSET.
.TP
.B -P
Specifies a P3P server privacy header to be returned with all responses.
See http://www.w3.org/P3P/ for details.
Thttpd doesn't do anything at all with the string except put it in the
P3P: response header.
The config-file option name for this flag is "p3p".
.TP
.B -M
Specifies the number of seconds to be used in a "Cache-Control: max-age"
header to be returned with all responses.
An equivalent "Expires" header is also generated.
The default is no Cache-Control or Expires headers,
which is just fine for most sites.
The config-file option name for this flag is "max_age".
.TP
.B -V
Shows the current version info.
.TP
.B -D
This was originally just a debugging flag, however it's worth mentioning
because one of the things it does is prevent thttpd from making itself
a background daemon.
Instead it runs in the foreground like a regular program.
This is necessary when you want to run thttpd wrapped in a little shell
script that restarts it if it exits.
.SH "CONFIG-FILE"
.PP
All the command-line options can also be set in a config file.
One advantage of using a config file is that the file can be changed,
and thttpd will pick up the changes with a restart.
.PP
The syntax of the config file is simple, a series of "option" or
"option=value" separated by whitespace.
The option names are listed above with their corresponding command-line flags.
.SH "CHROOT"
.PP
chroot() is a system call that restricts the program's view
of the filesystem to the current directory and directories
below it.
It becomes impossible for remote users to access any file
outside of the initial directory.
The restriction is inherited by child processes, so CGI programs get it too.
This is a very strong security measure, and is recommended.
The only downside is that only root can call chroot(), so this means
the program must be started as root.
However, the last thing it does during initialization is to
give up root access by becoming another user, so this is safe.
.PP
The program can also be compile-time configured to always
do a chroot(), without needing the -r flag.
.PP
Note that with some other web servers, such as NCSA httpd, setting
up a directory tree for use with chroot() is complicated, involving
creating a bunch of special directories and copying in various files.
With thttpd it's a lot easier, all you have to do is make sure
any shells, utilities, and config files used by your CGI programs and
scripts are available.
If you have CGI disabled, or if you make a policy that all CGI programs
must be written in a compiled language such as C and statically linked,
then you probably don't have to do any setup at all.
.PP
However, one thing you should do is tell syslogd about the chroot tree,
so that thttpd can still generate syslog messages.
Check your system's syslodg man page for how to do this.
In FreeBSD you would put something like this in /etc/rc.conf:
.nf
syslogd_flags="-l /usr/local/www/data/dev/log"
.fi
Substitute in your own chroot tree's pathname, of course.
Don't worry about creating the log socket, syslogd wants to do that itself.
(You may need to create the dev directory.)
In Linux the flag is -a instead of -l, and there may be other differences.
.PP
Relevant config.h option: ALWAYS_CHROOT.
.SH "CGI"
.PP
thttpd supports the CGI 1.1 spec.
.PP
In order for a CGI program to be run, its name must match the pattern
specified either at compile time or on the command line with the -c flag.
This is a simple shell-style filename pattern.
You can use * to match any string not including a slash,
or ** to match any string including slashes,
or ? to match any single character.
You can also use multiple such patterns separated by |.
The patterns get checked against the filename
part of the incoming URL.
Don't forget to quote any wildcard characters so that the shell doesn't
mess with them.
.PP
Restricting CGI programs to a single directory lets the site administrator
review them for security holes, and is strongly recommended.
If there are individual users that you trust, you can enable their
directories too.
.PP
If no CGI pattern is specified, neither here nor at compile time,
then CGI programs cannot be run at all.
If you want to disable CGI as a security measure, that's how you do it, just
comment out the patterns in the config file and don't run with the -c flag.
.PP
Note: the current working directory when a CGI program gets run is
the directory that the CGI program lives in.
This isn't in the CGI 1.1 spec, but it's what most other HTTP servers do.
.PP
Relevant config.h options: CGI_PATTERN, CGI_TIMELIMIT, CGI_NICE, CGI_PATH, CGI_LD_LIBRARY_PATH, CGIBINDIR.
.SH "BASIC AUTHENTICATION"
.PP
Basic Authentication is available as an option at compile time.
If enabled, it uses a password file in the directory to be protected,
called .htpasswd by default.
This file is formatted as the familiar colon-separated
username/encrypted-password pair, records delimited by newlines.
The protection does not carry over to subdirectories.
The utility program htpasswd(1) is included to help create and
modify .htpasswd files.
.PP
Relevant config.h option: AUTH_FILE
.SH "THROTTLING"
.PP
The throttle file lets you set maximum byte rates on URLs or URL groups.
You can optionally set a minimum rate too.
The format of the throttle file is very simple.
A # starts a comment, and the rest of the line is ignored.
Blank lines are ignored.
The rest of the lines should consist of a pattern, whitespace, and a number.
The pattern is a simple shell-style filename pattern, using ?/**/*, or
multiple such patterns separated by |.
.PP
The numbers in the file are byte rates, specified in units of bytes per second.
For comparison, a v.90 modem gives about 5000 B/s depending on compression,
a double-B-channel ISDN line about 12800 B/s, and a T1 line is about
150000 B/s.
If you want to set a minimum rate as well, use number-number.
.PP
Example:
.nf
# throttle file for www.acme.com
** 2000-100000 # limit total web usage to 2/3 of our T1,
# but never go below 2000 B/s
**.jpg|**.gif 50000 # limit images to 1/3 of our T1
**.mpg 20000 # and movies to even less
jef/** 20000 # jef's pages are too popular
.fi
.PP
Throttling is implemented by checking each incoming URL filename against all
of the patterns in the throttle file.
The server accumulates statistics on how much bandwidth each pattern
has accounted for recently (via a rolling average).
If a URL matches a pattern that has been exceeding its specified limit,
then the data returned is actually slowed down, with
pauses between each block.
If that's not possible (e.g. for CGI programs) or if the bandwidth has gotten
way larger than the limit, then the server returns a special code
saying 'try again later'.
.PP
The minimum rates are implemented similarly.
If too many people are trying to fetch something at the same time,
throttling may slow down each connection so much that it's not really
useable.
Furthermore, all those slow connections clog up the server, using
up file handles and connection slots.
Setting a minimum rate says that past a certain point you should not
even bother - the server returns the 'try again later" code and the
connection isn't even started.
.PP
There is no provision for setting a maximum connections/second throttle,
because throttling a request uses as much cpu as handling it, so
there would be no point.
There is also no provision for throttling the number of simultaneous
connections on a per-URL basis.
However you can control the overall number of connections for the whole
server very simply, by setting the operating system's per-process file
descriptor limit before starting thttpd.
Be sure to set the hard limit, not the soft limit.
.SH "MULTIHOMING"
.PP
Multihoming means using one machine to serve multiple hostnames.
For instance, if you're an internet provider and you want to let
all of your customers have customized web addresses, you might
have www.joe.acme.com, www.jane.acme.com, and your own www.acme.com,
all running on the same physical hardware.
This feature is also known as "virtual hosts".
There are three steps to setting this up.
.PP
One, make DNS entries for all of the hostnames.
The current way to do this, allowed by HTTP/1.1, is to use CNAME aliases,
like so:
.nf
www.acme.com IN A 192.100.66.1
www.joe.acme.com IN CNAME www.acme.com
www.jane.acme.com IN CNAME www.acme.com
.fi
However, this is incompatible with older HTTP/1.0 browsers.
If you want to stay compatible, there's a different way - use A records
instead, each with a different IP address, like so:
.nf
www.acme.com IN A 192.100.66.1
www.joe.acme.com IN A 192.100.66.200
www.jane.acme.com IN A 192.100.66.201
.fi
This is bad because it uses extra IP addresses, a somewhat scarce resource.
But if you want people with older browsers to be able to visit your
sites, you still have to do it this way.
.PP
Step two.
If you're using the modern CNAME method of multihoming, then you can
skip this step.
Otherwise, using the older multiple-IP-address method you
must set up IP aliases or multiple interfaces for the extra addresses.
You can use ifconfig(8)'s alias command to tell the machine to answer to
all of the different IP addresses.
Example:
.nf
ifconfig le0 www.acme.com
ifconfig le0 www.joe.acme.com alias
ifconfig le0 www.jane.acme.com alias
.fi
If your OS's version of ifconfig doesn't have an alias command, you're
probably out of luck (but see http://www.acme.com/software/thttpd/notes.html).
.PP
Third and last, you must set up thttpd to handle the multiple hosts.
The easiest way is with the -v flag, or the ALWAYS_VHOST config.h option.
This works with either CNAME multihosting or multiple-IP multihosting.
What it does is send each incoming request to a subdirectory based on the
hostname it's intended for.
All you have to do in order to set things up is to create those subdirectories
in the directory where thttpd will run.
With the example above, you'd do like so:
.nf
mkdir www.acme.com www.joe.acme.com www.jane.acme.com
.fi
If you're using old-style multiple-IP multihosting, you should also create
symbolic links from the numeric addresses to the names, like so:
.nf
ln -s www.acme.com 192.100.66.1
ln -s www.joe.acme.com 192.100.66.200
ln -s www.jane.acme.com 192.100.66.201
.fi
This lets the older HTTP/1.0 browsers find the right subdirectory.
.PP
There's an optional alternate step three if you're using multiple-IP
multihosting: run a separate thttpd process for each hostname, using
the -h flag to specify which one is which.
This gives you more flexibility, since you can run each of these processes
in separate directories, with different throttle files, etc.
Example:
.nf
thttpd -r -d /usr/www -h www.acme.com
thttpd -r -d /usr/www/joe -u joe -h www.joe.acme.com
thttpd -r -d /usr/www/jane -u jane -h www.jane.acme.com
.fi
But remember, this multiple-process method does not work with CNAME
multihosting - for that, you must use a single thttpd process with
the -v flag.
.SH "CUSTOM ERRORS"
.PP
thttpd lets you define your own custom error pages for the various
HTTP errors.
There's a separate file for each error number, all stored in one
special directory.
The directory name is "errors", at the top of the web directory tree.
The error files should be named "errNNN.html", where NNN is the error number.
So for example, to make a custom error page for the authentication failure
error, which is number 401, you would put your HTML into the file
"errors/err401.html".
If no custom error file is found for a given error number, then the
usual built-in error page is generated.
.PP
If you're using the virtual hosts option, you can also have different
custom error pages for each different virtual host.
In this case you put another "errors" directory in the top of that
virtual host's web tree.
thttpd will look first in the virtual host errors directory, and
then in the server-wide errors directory, and if neither of those
has an appropriate error file then it will generate the built-in error.
.SH "NON-LOCAL REFERRERS"
.PP
Sometimes another site on the net will embed your image files in their
HTML files, which basically means they're stealing your bandwidth.
You can prevent them from doing this by using non-local referrer filtering.
With this option, certain files can only be fetched via a local referrer.
The files have to be referenced by a local web page.
If a web page on some other site references the files, that fetch will
be blocked.
There are three config-file variables for this feature:
.TP
.B urlpat
A wildcard pattern for the URLs that should require a local referrer.
This is typically just image files, sound files, and so on.
For example:
.nf
urlpat=**.jpg|**.gif|**.au|**.wav
.fi
For most sites, that one setting is all you need to enable referrer filtering.
.TP
.B noemptyreferrers
By default, requests with no referrer at all, or a null referrer, or a
referrer with no apparent hostname, are allowed.
With this variable set, such requests are disallowed.
.TP
.B localpat
A wildcard pattern that specifies the local host or hosts.
This is used to determine if the host in the referrer is local or not.
If not specified it defaults to the actual local hostname.
.SH SYMLINKS
.PP
thttpd is very picky about symbolic links.
Before delivering any file, it first checks each element in the path
to see if it's a symbolic link, and expands them all out to get the final
actual filename.
Along the way it checks for things like links with ".." that go above
the server's directory, and absolute symlinks (ones that start with a /).
These are prohibited as security holes, so the server returns an
error page for them.
This means you can't set up your web directory with a bunch of symlinks
pointing to individual users' home web directories.
Instead you do it the other way around - the user web directories are
real subdirs of the main web directory, and in each user's home
dir there's a symlink pointing to their actual web dir.
.PP
The CGI pattern is also affected - it gets matched against the fully-expanded
filename. So, if you have a single CGI directory but then put a symbolic
link in it pointing somewhere else, that won't work. The CGI program will be
treated as a regular file and returned to the client, instead of getting run.
This could be confusing.
.SH PERMISSIONS
.PP
thttpd is also picky about file permissions.
It wants data files (HTML, images) to be world readable.
Readable by the group that the thttpd process runs as is not enough - thttpd
checks explicitly for the world-readable bit.
This is so that no one ever gets surprised by a file that's not set
world-readable and yet somehow is readable by the HTTP server and
therefore the *whole* world.
.PP
The same logic applies to directories.
As with the standard Unix "ls" program, thttpd will only let you
look at the contents of a directory if its read bit is on; but
as with data files, this must be the world-read bit, not just the
group-read bit.
.PP
thttpd also wants the execute bit to be *off* for data files.
A file that is marked executable but doesn't match the CGI pattern
might be a script or program that got accidentally left in the
wrong directory.
Allowing people to fetch the contents of the file might be a security breach,
so this is prohibited.
Of course if an executable file *does* match the CGI pattern, then it
just gets run as a CGI.
.PP
In summary, data files should be mode 644 (rw-r--r--),
directories should be 755 (rwxr-xr-x) if you want to allow indexing and
711 (rwx--x--x) to disallow it, and CGI programs should be mode
755 (rwxr-xr-x) or 711 (rwx--x--x).
.SH LOGS
.PP
thttpd does all of its logging via syslog(3).
The facility it uses is configurable.
Aside from error messages, there are only a few log entry types of interest,
all fairly similar to CERN Common Log Format:
.nf
Aug 6 15:40:34 acme thttpd[583]: 165.113.207.103 - - "GET /file" 200 357
Aug 6 15:40:43 acme thttpd[583]: 165.113.207.103 - - "HEAD /file" 200 0
Aug 6 15:41:16 acme thttpd[583]: referrer http://www.acme.com/ -> /dir
Aug 6 15:41:16 acme thttpd[583]: user-agent Mozilla/1.1N
.fi
The package includes a script for translating these log entries info
CERN-compatible files.
Note that thttpd does not translate numeric IP addresses into domain names.
This is both to save time and as a minor security measure (the numeric
address is harder to spoof).
.PP
Relevant config.h option: LOG_FACILITY.
.PP
If you'd rather log directly to a file, you can use the -l command-line
flag. But note that error messages still go to syslog.
.SH SIGNALS
.PP
thttpd handles a couple of signals, which you can send via the
standard Unix kill(1) command:
.TP
.B INT,TERM
These signals tell thttpd to shut down immediately.
Any requests in progress get aborted.
.TP
.B USR1
This signal tells thttpd to shut down as soon as it's done servicing
all current requests.
In addition, the network socket it uses to accept new connections gets
closed immediately, which means a fresh thttpd can be started up
immediately.
.TP
.B USR2
This signal tells thttpd to generate the statistics syslog messages
immediately, instead of waiting for the regular hourly update.
.TP
.B HUP
This signal tells thttpd to close and re-open its (non-syslog) log file,
for instance if you rotated the logs and want it to start using the
new one.
This is a little tricky to set up correctly, for instance if you are using
chroot() then the log file must be within the chroot tree, but it's
definitely doable.
