PYGOPHERD(8) PyGopherd Manual PYGOPHERD(8)NAME
PyGopherd - Multiprotocol Information Server
SYNOPSISpygopherd [ configfile ]
DESCRIPTION
Welcome to PyGopherd. In a nutshell, PyGopherd is a modern dynamic
multi-protocol hierarchical information server with a pluggable modu‐
larized extension system, full flexible caching, virtual files and
folders, and autodetection of file types -- all with support for stan‐
dardized yet extensible per-document metadata. Whew! Read on for infor‐
mation on this what all these buzzwords mean.
FEATURES
Here are some of PyGopherd's features:
· Provides built-in support for multiple protocols: HTTP (Web),
Gopher+, Gopher (RFC1436), Enhanced Gopher0, and WAP (mobile phones).
Protocols can be enabled or disabled as desired.
· Provides protocol autodetection. That is, PyGopherd can listen for
all the above protocols on a single port and will automatically
respond using the protocol it detects the client is using. Practical
effects of this are that you can, for instance, give out a single URL
and have it viewable normally on desktop Web browsers and in WAP mode
on mobile phones -- and appropriately in various Gopher browsers.
· Metadata and site links can be entered in a variety of formats,
including full UMN dotfile metadata formats as well as Bucktooth
gophermap files. Moreover, gophermap files are not limited to Gopher
protocols, and can be used for all protocols.
· Support for inter-protocol linking (linking from Gopher sites to web
sites)
· Virtual folder system lets you serve up anything as if it were regu‐
lar files and directories. PyGopherd comes with the following vir‐
tual folder systems built in:
· Can present any Unix MBOX, MMDF box, MH directory, Maildir direc‐
tory, or Babyl mailbox as a virtual folder, the contents of which
are the messages in the mailbox.
· Can use a configurable separator to split a file into multiple
parts, the first line of each becoming the name for the virtual
folder.
· Can peek inside a ZIP file and serve it up as first-class site cit‐
izens -- metadata can even be stored in the ZIP files.
· Can serve up the contents of a dictd server as a filesystem.
· Modular, extensible design: you can use PyGopherd's own PYG extension
format, or UMN- or Bucktooth-style executables.
· Runs on any platform supported by Python 2.2 or 2.3. This includes
virtually every past and current flavor of Unix (Linux, *BSD,
Solaris, SunOS), Windows, MacOS 9.x and X, and more. Some features
may not be available on non-Unix platforms.
· Runs on any platform supported by Java 1.1 via the Jython Python
implementation.
· Tunable server types via configuration directive -- forking or
threading.
· Secure design with support for chrooted execution.
· Feature-complete, full implementations of: Gopher0 (RFC1435),
Gopher+, HTTP, and WAP.
· Support for automatically finding the titles of HTML documents for
presentation in a directory.
· Versatile configuration file format is both extensible and nicely
complementary of the module system.
· Protocol-independant, handler-dependant caching. This increases per‐
formance by letting handlers cache dynamically-generated information
-- currently used by the directory handlers. This can improve per‐
formance of directories by several orders of magnitude. Because this
is a handler cache only, all protococls share the single cache.
Since the processing time for the protocols is negligable, this works
out very well.
· Autosensing of MIME types and gopher0 item types. Both are com‐
pletely configurable. MIME type detection is done using a standard
mime.types file, and gopher0 types are calculated by using a config‐
urable regexp-based MIME-to-gophertype map.
· Heavy support of regular expressions in configuration.
· ProtocolMultiplexer and HandlerMultiplexer let you choose only those
protocols and handlers that you wish your server to support and the
order in which they are tried when a request comes in.
· Full logging via syslog.
ABOUT GOPHER
PyGopherd started life as a server for the Gopher Internet protocol.
With Gopher, you can mount a filesystem (viewing files and folders as
if they were local), browse Gopherspace with a web browser, download
files, and be interactive with searching.
But this is only part of the story. The world of Gopher is more expan‐
sive than this. There are two major gopher protocols: Gopher0 (also
known as RFC1436) and Gopher+. Gopher0 is a small, simple, lightweight
protocol that is very functional yet also extremely easy to implement.
Gopher0 clients can be easily places in small embedded devices or in
massive environments like a modern web browser.
Gopher+ is based on Gopher0 but extends it by providing document meta‐
data such as file size and MIME type. Gopher+ allows all sorts of neat
features, such as configurable metadata (serving up a bunch of photos?
Add a Subject field to your metadata to let a customized photo browser
display who is pictured) and multiple views of a file (let the user
select to view your photos as PNG or JPEG).
QUICK START
If you have already installed PyGopherd system-wide, or your adminis‐
trator has done that for you, your task for setting up PyGopherd for
the first time is quite simple. You just need to set up your configu‐
ration file, make your folder directory, and run it!
You can quickly set up your configuration file. The distribution
includes two files of interest: conf/pygopherd.conf and
conf/mime.types. Debian users will find the configuration file pre-
installed in /usr/local/etc/pygopherd/pygopherd.conf and the mime.types
file provided by the system already.
Open up pygopherd.conf in your editor and adjust to suit. The file is
heavily commented and you can refer to it for detailed information.
Some settings to take a look at include: detach, pidfile, port, usech‐
root, setuid, setgid, and root. These may or may not work at their
defaults for you. The remaining ones should be fine for a basic setup.
Invoke PyGopherd with pygopherd path/to/configfile (or
/usr/local/etc/init.d/pygopherd start on Debian). Place some files in
the location specified by the root directive in the config file and
you're ready to run!
INSTALLATION
If you are reading this document via the "man" command, it is likely
that you have no installation tasks to perform; your system administra-
tor has already installed PyGopherd. If you need to install it your‐
self, you have three options: a system-wide installation with Debian,
system-wide installation with other systems, and a single-user
installation. You can download the latest version of
PyGopherd from
<URL:http://quux.org/devel/gopher/pygopherd/>
DEBIAN SYSTEM-WIDE INSTALLATION
If you are tracking Debian unstable, you may install PyGopherd by sim‐
ply running this command as root:
apt-get install pygopherd
If you are not tracking Debian unstable, download the .deb package from
the PyGopherd website and then run dpkg -i to install the downloaded
package. Then, skip to the configuration section below. You will use
/usr/local/etc/init.d/pygopherd start to start the program.
OTHER SYSTEM-WIDE INSTALLATION
Download the tar.gz version of the package from the website. Make sure
you have Python 2.2 or above installed; if now, download and install it
from <URL:http://www.python.org/>. Then run these commands:
tar -zxvf pygopherd-x.y.z.tar.gz
cd pygopherd-x.y.z
python2.2 setup.py
Some systems will use python or python2.3 in place of python2.2.
Next, proceed to configuration. Make sure that the
/usr/local/etc/pygopherd/pygopherd.conf file names valid users (setuid
and setgid options) and a valid document root (root option).
You will type pygopherd to invoke the program.
SINGLE-ACCOUNT INSTALLATION
Download the tar.gz version of the package from the website. Make sure
you have Python 2.2 or above installed; if now, download and install it
from <URL:http://www.python.org/>. Then run these commands:
tar -zxvf pygopherd-z.y.z.tar.gz
cd pygopherd-x.y.z
Modify conf/pygopherd.conf as follows:
· Set usechroot = no
· Comment out (add a # sign to the start of the line) the pidfile,
setuid, and setgid lines.
· Set root to osomething appropriate.
· Set port to a number greater than 1024.
When you want to run PyGopherd, you will issue the cd command as above
and then type PYTHONPATH=. bin/pygopherd. There is no installation
step necessary.
CONFIGURATION
PyGopherd is regulated by a configuratoin file normally stored in
/usr/local/etc/pygopherd/pygopherd.conf. You can specify an alternate
configuration file on the command line. The PyGopherd distribution
ships with a sample pygopherd.conf file that thoroughly documents the
configuration file options and settings.
OPTIONS
All PyGopherd configuratoin is done via the configuration file. There‐
fore, the program has only one command-line option:
configfile
This option argument specifies the location of the configuration
file that PyGopherd is to use.
HANDLERS
PyGopherd defines several handlers which are responsible for finding
data on your server and presenting it to the user. The handlers are
used to generate things like links to other documents and directory
listings. They are also responsible for serving up regular files and
even virtual folders.
Handlers are specified with the handlers option in pygopherd.conf.
This option is a list of handlers to use. For each request that
arrives, PyGopherd will ask each handler in turn whether or not it can
handle the request, and will handle the request according to the first
handler that is capable of doing so. If no handlers can handle the
request, a file not found error is generated. See the example configu‐
ration file for an example.
The remaining parts of this section describe the different handlers
that ship with PyGopherd. Please note that some versions of this man‐
ual may show the handlers in all caps; however, their names are not all
caps and are case-sensitive.
DIR.DIRHANDLER
This handler is a basic one that generates menus based on the contents
of a directory. It is used for directories that contain neither a
gophermap file nor UMN-style links files, or situations where you have
no need for either of those.
This handler simply reads the contents of your on-disk directory,
determines the appropriate types of each file, and sends the result to
the client. The descriptions of each item are usually set to the file‐
name, but the html.HTMLFileTitleHandler may override that.
GOPHERMAP.BUCKGOPHERMAPHANDLER
This handler is used to generate directory listings based on gophermap
files. It will not read the directory on-disk, instead serving content
from the gophermap file only. Gophermaps are useful if you want to
present a directory in which the files do not frequently change and
there is general information to present. Overall, if you only wish to
present information particular to certain files, you should consider
using the abstract feature of UMN.UMNDirHandler.
The gophermap files contain two types of lines, which are described
here using the same convention normally used for command line argu‐
ments. In this section, the symbol \t will be used to indicate a tab
character, Control-I.
full line of informational text
gophertypeDESCRIPTION [ \tselector [ \thost [ \tport ] ] ]
Note: spaces shown above are for clarity only and should not actually
be present in your file.
The informational text must not contain any tab characters, but may
contain spaces. Informational text will be rendered with gopher type
i, which will cause it to be displayed on a client's screen at its par‐
ticular position in the file.
The second type of line represents a link to a file or directory. It
begins with a single-character Gopher type (see Gopher Item Types
below) followed immediately by a description and a tab character.
There is no space or other separator between the gopher type and the
description. The description may contain spaces but not tabs.
The remaining arguments are optional, but only to the extent that argu‐
ments may be omitted only if all arguments after them are also omitted.
These arguments are:
selector
The selector is the name of the file on the server. If it
begins with a slash, it is an absolute path; otherwise, it is
interpreted relative to the directory that the gophermap file is
in. If no selector is specified, the description is also used
as the selector.
host The host specifies the host on which this resource is located.
If not specified, defaults to the current server.
port The port specifies the port on which the resource is located.
If not specified, defaults to the port the current server is
listening on.
An example of a gophermap to help illustrate the concept is included
with the PyGopherd distribution in the file examples/gophermap.
FILE.COMPRESSEDFILEHANDLER
In order to save space, you might want to store documents on-disk in a
compressed format. But then clients would ordinarily have to decom‐
press the files themselves. It would be nice to have the server auto‐
matically decompress the files on the fly, sending that result to the
client. That's where file.CompressedFileHandler comes in.
This handler will take compressed files, pipe them through your chosen
decompression program, and send the result directly to clients -- com‐
pletely transparently.
To use this handler, set the decompressors option in the configuration
file. This option defines a mapping from MIME encodings (as defined
with the encoding option) to decompression programs. Files that are
not encoded, or which have an encoding that does not occur in the
decompressors map, will not be decompressed by this handler.
Please see the sample configuration file for more examples and details
about the configuration of this handler.
FILE.FILEHANDLER
The file.FileHandler is just that -- its duty is to serve up regular
files to clients.
HTML.HTMLFILETITLEHANDLER
This handler is used when generating directories and will set the
description of HTML files to the HTML title defined in them rather than
let it be the default filename. Other than that, it has no effect.
UMN gopherd implements a similar policy.
MBOX HANDLERS
There are four mailbox handlers:
· mbox.MaildirFolderHandler
· mbox.MaildirMessageHandler
· mbox.MBoxMessageHandler
· mbox.MBoxFolderHandler
These four handlers provide a unique "virtual folder" service. They
allow you to present mailboxes as if they were folders, the items of
the folders being the messages in the mailbox, organized by subject.
This is useful for presenting mail archives or just making e-mail
accessible in a nice and easy fashion.
To use these handlers, all you have to do is enable them in your han‐
dlers section. They will automatically detect requests for mailboxes
and handle them appropriately.
The different handlers are for traditional Unix mbox mailboxes (all
messages in a single file) and new qmail-stype Maildir mailboxes. You
can enable only the two handlers for the specific mailbox type that you
use, if desired.
PYG.PYGHANDLER
PYG (short for PYGopherd) is a mechanism that provides a tremendous
amount of flexibility. Rather than just letting you execute a script
like other Gopher or HTTP servers, PYGs are actually loaded up into
PyGopherd and become fully-capable first-class virtual handlers. Yet
they need not be known ahead of time, and are loaded dynamically.
With a PYG handler, you can generate gopher directories, handle
searches, generate files, and more on the fly. You can create entire
virtual directory trees (for instance, to interface with NNTP servers
or with DICT servers), and access them all using the standard Gopher
protocol. All of this without having to modify even one line of PyGo‐
pherd code.
If enabled, the pyg.PYGHandler will look for files with the extension
.pyg that are marked executable. If found, they will be loaded and run
as PYGs.
Please note: this module provides the capability to execute arbitrary
code. Please consider the security ramifications of that before
enabling it.
See the virtual.Virtual handler for more information about passing data
to your scripts at runtime.
At present, documentation on writing PYGs is not provides, but you may
find examples in the pygfarm directory included with the PyGopherd dis‐
tribution.
SCRIPTEXEC.EXECHANDLER
This handler implements "old-style" script execution; that is, execut‐
ing arbitrary programs and piping the result to the client. It is, for
the most part, compatible with both scripts written for UMN gopherd and
the Bucktooth gopher server. If enabled, it will execute any file that
is marked executable in the filesystem. It will normally list scripts
as returning plain text, but you may create a custom link to the script
that defines it as returning whatever kind of file you desire. Unlike
PYGs, this type must be known in advance.
The scriptexec.ExecHandler will set environment variables for your
scripts to use. They are as follows:
SERVER_NAME
The name of this server as defined in the configuration file or
detected from the operating system.
SERVER_PORT
The port this server is listening on.
REMOTE_ADDR
The IP address of the client.
REMOTE_PORT
The port number of the client.
REMOTE_HOST
The same value as REMOTE_ADDR
SELECTOR
The file that was requested; that is, the relative path to this
script. If the selector included additional parameters after a
|, they will be included in this string as well.
REQUEST
The "base" part of the selector; that is, the part leading up to
the |.
SEARCHREQUEST
Included only if the client specified search data, this is used
if the client is searching for something.
See the virtual.Virtual handler for more information about passing data
to your scripts at runtime.
Please note: this module provides the capability to execute arbitrary
code. Please consider the security ramifications of that before
enabling it.
UMN.UMNDIRHANDLER
This is one of the most powerful workhorse handlers in PyGopherd. It
is designed to emulate most of the ways in which the UMN gopherd dis‐
tribution generates directories, even going so far as to be bug-compat‐
ible in some cases. Generating directories with this handler is often
the best general-purpose way to make nice directories in gopherspace.
The remainder of the description of the UMN.UMNDirHandler, except for
the Abstracts and Info section, is lifted directly from the original
UMN gopherd documentation, with light editing, because this handler
implements it so exactly that there was no point in rewriting all that
documentation :-)
LINKS
You can override the default view of a directory as generated by
dir.DirHandler by creating what are known as Links in the data tree.
The ability to make links to other hosts is how gopher distributes
itself among multiple hosts. There are two different ways to make a
link. The first and simplest is to create a link file that contains
the data needed by the server. By default all files in the gopher data
directory starting with a period are taken to be link files. A link
file can contain multiple links. To define a link you need to put five
lines in a link file that define the needed characteristics for the
document. Here is an example of a link.
Name=Cheese Ball Recipes
Numb=1
Type=1
Port=150
Path=1/Moo/Cheesy
Host=zippy.micro.umn.edu
The Name= line is what the user will see when cruising through the
database. In this case the name is "Cheese Ball Recipes". The "Type="
defines what kind of document this object is. For a list of all
defined types, see Gopher Item Types below. For Gopher+ and HTTP, a
MIME type is also used, which is determined automatically based on the
type you specify.
The "Path=" line contains the selector string that the client will use
to retrieve the actual document. The Numb= specifies that this entry
should be presented first in the directory list (instead of being
alphabetized). The "Numb=" line is optional. If it is present it can‐
not be the last line of the link. The "Port=" and "Host=" lines spec‐
ify a fully qualified domain name (FQDN) and a port respectively. You
may substitute a plus '+' for these two parameters if you wish. The
server will insert the current hostname and the current port when it
sees a plus in either of these two fields.
An easy way to retrieve links is to use the Curses Gopher Client. By
pressing '=' You can get information suitable for inclusion in a link
file.
OVERRIDING DEFAULTS
The server looks for a directory called .cap when parsing a directory.
The server then checks to see if the .cap directory contains a file
with the same name as the file it's parsing. If this file exists then
the server will open it for reading. The server parses this file just
like a link file. However, instead of making a new object, the parame‐
ters inside the .cap/ file are used to override any of the server sup‐
plied default values.
For instance, say you wanted to change the Title of a text file for
gopher, but don't want to change the filename. You also don't want it
alphabetized, instead you want it second in the directory listing. You
could make a set-aside file in the .cap directory with the same file‐
name that contained the following lines:
Name=New Long Cool Name
Numb=2
An alternative to .cap files are extended link files. They work just
the same as the files described in Links above, but have a somewhat
abbreviated format. As an example, if the name of the file was file-
to-change, then you could create a file called .names with the follow‐
ing contents:
Path=./file-to-change
Name=New Long Cool Name
Numb=2
ADDING COOL LINKS
One cool thing you can do with .Links is to add neato services to your
gopher server. Adding a link like this:
Name=Cool ftp directory
Type=h
Path=/URL:ftp://hostname/path/
Host=+
Port=+
Name=Cool web site
Type=h
Path=/URL:http://hostname/
Host=+
Port=+
Will allow you to link in any FTP or Web site to your gopher. (See
url.URLHandler for more details.)
You can easily add a finger site to your gopher server thusly:
Name=Finger information
Type=0
Path=lindner
Host=mudhoney.micro.umn.edu
Port=79
HIDING AN ENTRY
This kind of trick may be necessary in some cases, and thus for object
"fred", the overriding .names file entry would be:
Type=X
Path=./fred
by overriding default type to be "X". This kind of hideouts may be
usefull, when for some reason there are symlinks (or whatever) in the
directory at which PyGopherd looks at, and those entries are not
desired to be shown at all.
ABSTRACTS AND INFO
Many modern gopher server maintainers like to intersperse gopher direc‐
tory listings with other information -- often, additional information
about the contents of files in the directory. The gophermap system
provides one way to do that, and abstracts used with UMN gopher direc‐
tories provides another.
Subject to the abstract_headers and abstract_entries configuration file
options, this feature allows you to define that extra information. You
can do that by simply creating a file named filename.abstract right
alongside the regular file in your directory. The file will be inter‐
preted as the abstract. For a directory, create a file named .abstract
in the directory. Simple as that!
URL.HTMLURLHANDLER
PyGopherd provides ways for you to link to pages outside Gopherspace --
that is, web pages, FTP sites, and the like. This is accomplished
according to the Links to URL <URL:http://lists.com‐
plete.org/gopher@complete.org/2002/02/msg00033.html.gz> specification
(see Conforming To below for details). In order to link to a URL
(EXCEPT gopher URLs) from a menu, you create a link of type h (regard‐
less of the actual type of the resource that you are linking to) in
your gophermap or .Links file that looks like this:
/URL:http://www.complete.org/
Modern Gopher clients that follow the Links to URL specification will
automatically follow that link when you select it. The rest need some
help, and that's where this handler comes in.
For Gopher clients that do not follow the Links to URL specification,
the url.HTMLURLHandler will automatically generate an HTML document for
them on the fly. This document includes a refresh code that will send
them to the proper page. You should not disable this handler.
URL.URLTYPEREWRITER
Some people wish to serve HTML documents from their Gopher server. One
problem with that is that links in Gopherspace include an extra type
character at the beginning, whereas links in HTTP do not. This handler
will remove the extra type character from HTTP requests that come in,
allowing a single relative-to-root link to work for both.
VIRTUAL.VIRTUAL
This handler is not intended to ever be used directly, but is used by
many other handlers such as the mbox support, PYG handlers, and others.
It is used to generate virtual entries in the directory hierarchy --
that is, entries that look normal to a client, but do not actually cor‐
respond to a file on disk.
One special feature of the virtual.Virtual handler is that you can send
information to it at runtime in a manner similar to a CGI script on the
web. You do this by adding a question mark after the regular selector,
followed by any arbitrary data that you wish to have sent to the vir‐
tual request handler.
ZIP.ZIPHANDLER
Using zip.ZIPHandler, you can save space on your server by converting
part or all of your site into a ZIP file. PyGopherd can use the con‐
tents of that ZIP file as the contents of your site -- completely
transparently.
The ZIP file handler must be enabled in the configuration file for this
to work.
GOPHER ITEM TYPES
When you construct links to files via .Links or gophermap files, or
modify the mapping in the configuration file, you will need to know
these. Items bearing the "not implemented" text are not served up by
PyGopherd as it ships, generally due to requirements of customized per-
site software, but may be served up via PYG extension modules or other
gopher servers.
This list was prepared based on RFC1436, the UMN gopherd(1) manpage,
and best current practices.
0 Plain text file
1 Directory
2 CSO phone book server (not implemented by PyGopherd)
3 Error condition; text that follows is plain text
4 Macintosh file, BinHex format
5 DOS binary archive (not implemented by PyGopherd; use type 9
instead)
6 uuencoded file; not directly generated by PyGopherd automati‐
cally, but can be linked to manually. Most gopher clients will
handle this better as type 1.
7 Search
8 Telnet link
9 Binary file
+ Redundant server (not implemented by PyGopherd)
c Calendar (not implemented by PyGopherd)
e Event (not implemented by PyGopherd)
g GIF-format graphic
h HTML file
I Any kind of graphic file other than GIF
i Informational text included in a directory that is displayed but
does not link to any actual file.
M MIME multipart/mixed file
s Any kind of sound file
T tn3270 link
X
- UMN-specific -- signifies that this entry should not be dis‐
played in a directory entry, but may be accessed via a direct
link. This value is never transmitted in any Gopher protocol.
