Compiling and installing Gophernicus
|
||||
====================================
|
||||
|
||||
Gophernicus requires a C compiler but no extra libraries aside
|
||||
from standard LIBC ones. Care has been taken to use only
|
||||
standard POSIX syscalls so that it should work pretty much on
|
||||
any *nix system. Compiling has only been tested with GCC, but
|
||||
it will most likely work with others too.
|
||||
|
||||
To compile and install run:
|
||||
|
||||
$ gzip -cd gophernicus-*.tar.gz | tar xvf -
|
||||
$ cd gophernicus-*
|
||||
$ make
|
||||
$ sudo make install
|
||||
|
||||
Then add the below line to your /etc/inetd.conf and restart
|
||||
inetd. If your system comes with something else than standard
|
||||
inetd "make install" should have done the right thing already.
|
||||
|
||||
gopher stream tcp nowait nobody /usr/sbin/in.gophernicus in.gophernicus -h <hostname>
|
||||
|
||||
The -h <hostname> parameter is mandatory for a properly working
|
||||
Gophernicus. Other parameters can also be added, see the full
|
||||
list by running "/usr/sbin/in.gophernicus -?"
|
||||
|
||||
By default Gophernicus serves gopher documents from /var/gopher
|
||||
although that can be changed by using the -r <root> parameter.
|
||||
To enable virtual hosting create hostname directories under
|
||||
the gopher root and make sure you have at least the primary
|
||||
hostname (the one set with -h <hostname>) directory available
|
||||
(mkdir /var/gopher/$HOSTNAME).
|
||||
|
||||
|
||||
Compiling on Debian Linux (and Ubuntu)
|
||||
======================================
|
||||
|
||||
The above commands work on Debian just fine, but if you prefer
|
||||
having everything installed as packages run "make deb" instead
|
||||
of plain "make". If all the dependencies were in place you'll
|
||||
end up with an offical-looking deb package in the parent
|
||||
directory (don't ask - that's just how it works). And instead
|
||||
of "sudo make install" you should just install the deb with
|
||||
"dpkg -i ../gophernicus_*.deb" after which It Should Just
|
||||
Work(tm).
|
||||
|
||||
|
||||
Compiling on Mac OS X
|
||||
=====================
|
||||
|
||||
When you run "make install" on OSX-like system with launchd
|
||||
the install routine also installs a plist file and tells launchd
|
||||
to start the server up. In other words, It Just Works(tm).
|
||||
|
||||
|
||||
Cross-compiling
|
||||
===============
|
||||
|
||||
Cross-compiling to a different target architecture can be done
|
||||
by defining HOSTCC and CC to be different compilers. HOSTCC
|
||||
must point to a local arch compiler, and CC to the target
|
||||
arch one.
|
||||
|
||||
$ make HOSTCC=gcc CC=target-arch-gcc
|
||||
|
||||
|
||||
Shared memory issues
|
||||
====================
|
||||
|
||||
Gophernicus uses SYSV shared memory for session tracking and
|
||||
statistics. It creates the shared memory block using mode 600
|
||||
and a predefined key which means that a shared memory block
|
||||
created with one user cannot be used by another user. Simply
|
||||
said, running in.gophernicus as yourself will allocate that
|
||||
memory, and then running the binary through inetd as another
|
||||
user (nobody) will be denied access to that memory.
|
||||
|
||||
If that happens you can simply delete the memory block and
|
||||
let Gophernicus recreate it - no harm done.
|
||||
|
||||
$ su -
|
||||
# ipcs -m | grep beeb
|
||||
# ipcrm -M <key from the above command>
|
||||
|
||||
|
||||
Porting to different platforms
|
||||
==============================
|
||||
|
||||
If you need to port Gophernicus to a new platform, please take
|
||||
a look at gophernicus.h which has a bunch of HAVE_* #defines.
|
||||
Fiddling with those usually makes it possible to compile a working
|
||||
server. If you succeed in compiling Gophernicus to a new
|
||||
platform please send the patches to kim@holviala.com so I can
|
||||
include them into the next release.
|
||||
|
||||
Tested (and semi-supported) platforms include:
|
||||
|
||||
OS Arch Compiler

Setting up a gopher site
|
||||
========================
|
||||
|
||||
After succesfully installing Gophernicus (see INSTALL) you need to set
|
||||
up the gopher root directory. By default Gophernicus serves documents
|
||||
from /var/gopher so start by creating that directory and making sure
|
||||
it's world-readable. Then, simply add files and directories under your
|
||||
root, fire up a gopher browser (Firefox, Lynx) and open up this URL:
|
||||
|
||||
gopher://<HOSTNAME>/ (where <HOSTNAME> is your servers hostname)
|
||||
|
||||
That's it, your first gopher site is now up and running. If the links
|
||||
on the root menu don't work, make sure you are using the -h <HOSTNAME>
|
||||
parameter in your inetd.conf (with a valid resolveable hostname
|
||||
instead of <HOSTNAME> - see INSTALL).
|
||||
|
||||
|
||||
Security
|
||||
========
|
||||
|
||||
Gophernicus has been written with high security in mind. There should
|
||||
be no buffer overflows or memory allocation problems so it should be
|
||||
safe to run a publicly available gopher server with Gophernicus.
|
||||
|
||||
However, the security settings (which are non-changeable) are so strict
|
||||
that you need to keep one thing in mind. Gophernicus will only serve
|
||||
world-readable content. Being readable by the server process is not
|
||||
enough, all files and directories MUST be world-readable or they are
|
||||
simply hidden from all listings and denied if a client asks for them.
|
||||
|
||||
|
||||
Gophermaps
|
||||
==========
|
||||
|
||||
By default all gopher menus are automatically generated from the
|
||||
content of the directory being viewed. If you want to have
|
||||
informational text along with the files, or if you want to completely
|
||||
replace the generated menu with your own you need to take a look at
|
||||
gophermaps. See the file README.gophermap for more information.
|
||||
|
||||
|
||||
Gophertags
|
||||
==========
|
||||
|
||||
A gophertag file can be used to virtually rename a directory. Let's
|
||||
assume that you have a directory called "foo" somewhere - it will
|
||||
be listed as "foo" in all automatically generated menus. Now if you
|
||||
create a file foo/gophertag and put the text "bar" into it the menus
|
||||
will show "bar" but the links will still point to "foo". This is
|
||||
useful for creating descriptive names for directories without
|
||||
littering the file system with spaces and weird characters.
|
||||
|
||||
|
||||
Personal gopherspaces
|
||||
=====================
|
||||
|
||||
Gophernicus supports users personal gopherspaces. If a user has
|
||||
world-readable directory called public_gopher/ under his home, a
|
||||
request for gopher://<HOSTNAME>/1/~user/ will serve documents from
|
||||
that directory.
|
||||
|
||||
|
||||
Virtual hosting
|
||||
===============
|
||||
|
||||
Gophernicus supports virtual hosting, or serving more than one logical
|
||||
domain using the same IP address. Since gopher (RFC1436) doesn't
|
||||
support virtual hosting this requires some clever (but mostly invisble)
|
||||
hacks.
|
||||
|
||||
To enable virtual hosting create one or more directories under your
|
||||
gopher root which are named after your domain names. The primary vhost
|
||||
directory (set with the -h <HOSTNAME> option) must exist or virtual
|
||||
hosting will be disabled. Then simply add content to the hostname
|
||||
directories and you're up and running.
|
||||
|
||||
Almost.
|
||||
|
||||
To make gopher clients work properly with virtual hosting, create a
|
||||
root gophermap for each of your domains and include the "%" type
|
||||
character to create a list of all available virtual hosts (see
|
||||
README.gophermap). The generated virtual host links will be created so
|
||||
that standard gopher clients will find the correct domain even when
|
||||
they don't specifically tell the server which host they're trying to
|
||||
reach.
|
||||
|
||||
|
||||
CGI support
|
||||
===========
|
||||
|
||||
Gophernicus supports most parts of the CGI/1.1 standard. Most standard
|
||||
CGI variables are set, and some non-standard ones are added.
|
||||
|
||||
By default all scripts and binaries under any directory called
|
||||
/cgi-bin/ are executed as CGI scripts (this includes cgi-bin
|
||||
directories under users personal gopherspaces). Also, if a gophermap
|
||||
is marked executable it is also processed as an CGI script.
|
||||
|
||||
As with regular files, CGI scripts must be world-executable (and
|
||||
readable) or they will be ignored. Make sure your CGI script is safe
|
||||
with ANY user input as poorly coded CGI scripts are the number #1
|
||||
security problem with publicly open *nix servers.
|
||||
|
||||
|
||||
Output filtering and PHP support
|
||||
================================
|
||||
|
||||
In addition to CGI scripts Gophernicus supports output filtering
|
||||
scripts. By default output filtering is turned off, but you can turn
|
||||
it on by using the -f <FILTERDIR> option, creating that directory
|
||||
and creating one or more scripts in there named by either the file
|
||||
suffix, or by the gopher filetype char.
|
||||
|
||||
If a file is to be served out which matches either the file suffix
|
||||
script, or the filetype script then instead of simply sending the
|
||||
file to client the output filter script is executed with the
|
||||
original file as the first parameter and the output of the script
|
||||
is then sent to client.
|
||||
|
||||
For PHP support install the CLI version of the PHP interpreter and
|
||||
then symlink (or copy) that binary to the directory specified with
|
||||
-f option using the destination name "php".
|
||||
|
||||
$ ln -s /usr/bin/php5-cli /usr/lib/gophernicus/filters/php
|
||||
|
||||
After that all files with the php suffix will be "filtered" through
|
||||
the PHP command line interpreter. In other words, PHP starts working.
|
||||
And don't use the CGI version of PHP as it outputs HTTP headers the
|
||||
gopher protocol doesn't have.
|
||||
|
||||
|
||||
Charset support and conversions
|
||||
===============================
|
||||
|
||||
Gophernicus supports three charsets: US-ASCII, ISO-8859-1 and UTF-8.
|
||||
All textual input is internally upconverted to UTF-8 and then
|
||||
downconverted to whatever charset the client is asking for. The
|
||||
conversion is input autosensing which means that you don't have to
|
||||
specify your filesystem charset, or the charset of your text files -
|
||||
it's all detected automatically.
|
||||
|
||||
With standard gopher clients this is a bit of a problem as your text
|
||||
files WILL be converted to 7-bit US-ASCII. This means that all 8-bit
|
||||
charaters WILL BE LOST. This decision was made because no gopher
|
||||
client that I tested was reliably cabable of decoding anything else
|
||||
than pure US-ASCII. If you want to disable the conversion use the
|
||||
"-no" option, or if you'd like to change the default output charset to
|
||||
something else than US-ASCII just use for example the "-o ISO-8859-1"
|
||||
option.
|
||||
|
||||
|
||||
Selector rewriting
|
||||
==================
|
||||
|
||||
Selector rewriting lets you rewrite parts of the selector on the fly.
|
||||
Well, not parts, but really just the start of it. And the rewrite
|
||||
enging here is nothing like Apache's mod_rewrite as I was too lazy
|
||||
to integrate any regex libraries... So, all it does is rewrite a
|
||||
fixed string at the start of the selector to something else. This
|
||||
will let you move your directories around while making sure that
|
||||
existing deeplinks still work.
|
||||
|
||||
Examples:
|
||||
|
||||
-R "/~user=/~luser"
|
||||
-R "/old-dir=/new-dir"
|
||||
|
||||
|
||||
Session tracking and statistics
|
||||
===============================
|
||||
|
||||
To enable virtual hosting with gopher (RFC1436) clients Gophernicus
|
||||
tracks users and their session. As a side effect of that session
|
||||
tracking, Gophernicus has simple throttling controls to keep nasty
|
||||
users from killing your precious 120MHz PPC 604e server from dying
|
||||
under the load. The throttling defaults are high enough that normal
|
||||
human users will never hit the limits, but it's possible (and mostly
|
||||
preferrable) that a badly behaving crawling agent will be throttled.
|
||||
|
||||
The current sessions and other real-time status data can be viewed
|
||||
by opening the URL gopher://<HOSTNAME>/0/server-status . This status
|
||||
view has been modeled after the Apache server-status which means
|
||||
that it's possible to integrate Gophernicus into existing server
|
||||
monitoring systems. To ease up such integrations, Gophernicus
|
||||
supports HTTP requests of the server-status page using an URL like
|
||||
http://<HOSTNAME>:70/server-status?auto

!Sample gophermap for Gophernicus
|
||||
|
||||
##
|
||||
## This is a sample gophermap.
|
||||
##
|
||||
#
|
||||
Creating a file called "gophermap" into a directory disables the
|
||||
normal resource listing and replaces it with the contents of the map
|
||||
file. You can also have inline gophermaps - files with a ".gophermap"
|
||||
extension are parsed as gophermaps and displayed in between normal
|
||||
resources in alphabetical order.
|
||||
|
||||
In a gophermap any line that doesn't contain a <TAB> character is
|
||||
automatically converted to an type "i" gopher resource which are
|
||||
displayed as plain text in the client. Lines which contain tabs are
|
||||
intepreted as gopher resource lines which the client will render as
|
||||
links. The first line of a gophermap should be a !Title line
|
||||
describing the menu.
|
||||
|
||||
Dynamic gophermaps are possible by making the gophermap a script and
|
||||
marking it as executable. All script output is parsed just like a
|
||||
static gophermap, for example lines without tabs are converted to "i"
|
||||
resources. Executable gophermaps are always ran through the default
|
||||
shell (/bin/sh) so depending on your operating system that's either
|
||||
slow, or really unbearably slow...
|
||||
|
||||
The format of a gophermap resource line is simple:
|
||||
Xname<TAB>selector<TAB>host<TAB>port
|
||||
|
||||
Where:
|
||||
X is the gopher filetype
|
||||
name is an explanation of the resource
|
||||
selector is the path to resource
|
||||
host:port are the hostname and port number to go to
|
||||
|
||||
Type and name are mandatory. If you don't specify a selector, the
|
||||
name field will be also used as the selector. If you don't specify
|
||||
host or port the host:port of the current server are used instead.
|
||||
Also make sure to use ONLY ONE TAB between the fields.
|
||||
|
||||
Valid filetypes include:
|
||||
0 text file
|
||||
1 directory
|
||||
3 error message
|
||||
5 archive file (zip, tar etc)
|
||||
7 search query
|
||||
8 telnet session
|
||||
9 binary file
|
||||
g GIF image
|
