# One use of the queue is to determine if we should or shouldn't

# announce the availability of a new CPAN module
|

|
||
# Now we try to use it for dependency tracking. For that to happen
|
||
# we need to draw a dependency tree and do the leaves first. This can
|
||
# easily be reached by running CPAN.pm recursively, but we don't want
|
||
# to waste memory and run into deep recursion. So what we can do is
|
||
# this:
|
||
|
||
# CPAN::Queue is the package where the queue is maintained. Dependencies
|
||
# often have high priority and must be brought to the head of the queue,
|
||
# possibly by jumping the queue if they are already there. My first code
|
||
# attempt tried to be extremely correct. Whenever a module needed
|
||
# immediate treatment, I either unshifted it to the front of the queue,
|
||
# or, if it was already in the queue, I spliced and let it bypass the
|
||
# others. This became a too correct model that made it impossible to put
|
||
# an item more than once into the queue. Why would you need that? Well,
|
||
# you need temporary duplicates as the manager of the queue is a loop
|
||
# that
|
||
#
|
||
# (1) looks at the first item in the queue without shifting it off
|
||
#
|
||
# (2) cares for the item
|
||
#
|
||
# (3) removes the item from the queue, *even if its agenda failed and
|
||
# even if the item isn't the first in the queue anymore* (that way
|
||
# protecting against never ending queues)
|
||
#
|
||
# So if an item has prerequisites, the installation fails now, but we
|
||
# want to retry later. That's easy if we have it twice in the queue.
|
||
#
|
||
# I also expect insane dependency situations where an item gets more
|
||
# than two lives in the queue. Simplest example is triggered by 'install
|
||
# Foo Foo Foo'. People make this kind of mistakes and I don't want to
|
||
# get in the way. I wanted the queue manager to be a dumb servant, not
|
||
# one that knows everything.
|
||
#
|
||
# Who would I tell in this model that the user wants to be asked before
|
||
# processing? I can't attach that information to the module object,
|
||
# because not modules are installed but distributions. So I'd have to
|
||
# tell the distribution object that it should ask the user before
|
||
# processing. Where would the question be triggered then? Most probably
|
||
# in CPAN::Distribution::rematein.

=head1 NAME
|
||
|

CPAN - query, download and build perl modules from CPAN sites
|
||
|
||
=head1 SYNOPSIS
|
||
|
||
Interactive mode:
|
||
|
||
perl -MCPAN -e shell;
|
||
|
||
Batch mode:
|
||
|
||
use CPAN;
|
||
|
||
autobundle, clean, install, make, recompile, test
|
||
|
||
=head1 DESCRIPTION
|
||
|
||
The CPAN module is designed to automate the make and install of perl
|
||
modules and extensions. It includes some searching capabilities and
|
||
knows how to use Net::FTP or LWP (or lynx or an external ftp client)
|
||
to fetch the raw data from the net.
|
||
|
||
Modules are fetched from one or more of the mirrored CPAN
|
||
(Comprehensive Perl Archive Network) sites and unpacked in a dedicated
|
||
directory.
|
||
|
||
The CPAN module also supports the concept of named and versioned
|
||
'bundles' of modules. Bundles simplify the handling of sets of
|
||
related modules. See BUNDLES below.
|
||
|
||
The package contains a session manager and a cache manager. There is
|
||
no status retained between sessions. The session manager keeps track
|
||
of what has been fetched, built and installed in the current
|
||
session. The cache manager keeps track of the disk space occupied by
|
||
the make processes and deletes excess space according to a simple FIFO
|
||
mechanism.
|
||
|
||
For extended searching capabilities there's a plugin for CPAN available,
|
||
L<CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine that indexes
|
||
all documents available in CPAN authors directories. If C<CPAN::WAIT>
|
||
is installed on your system, the interactive shell of <CPAN.pm> will
|
||
enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands which send
|
||
queries to the WAIT server that has been configured for your
|
||
installation.
|
||
|
||
All other methods provided are accessible in a programmer style and in an
|
||
interactive shell style.
|
||
|
||
=head2 Interactive Mode
|
||
|
||
The interactive mode is entered by running
|
||
|
||
perl -MCPAN -e shell
|
||
|
||
which puts you into a readline interface. You will have the most fun if
|
||
you install Term::ReadKey and Term::ReadLine to enjoy both history and
|
||
command completion.
|
||
|
||
Once you are on the command line, type 'h' and the rest should be
|
||
self-explanatory.
|
||
|
||
The most common uses of the interactive modes are

=item Searching for authors, bundles, distribution files and modules
|
||
|
||
There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
|
||
for each of the four categories and another, C<i> for any of the
|
||
mentioned four. Each of the four entities is implemented as a class
|
||
with slightly differing methods for displaying an object.
|
||
|
||
Arguments you pass to these commands are either strings exactly matching
|
||
the identification string of an object or regular expressions that are
|
||
then matched case-insensitively against various attributes of the
|
||
objects. The parser recognizes a regular expression only if you
|
||
enclose it between two slashes.
|
||
|
||
The principle is that the number of found objects influences how an
|
||
item is displayed. If the search finds one item, the result is displayed
|
||
as object-E<gt>as_string, but if we find more than one, we display
|
||
each as object-E<gt>as_glimpse. E.g.

||
=item make, test, install, clean modules or distributions
|
||
|
||
These commands take any number of arguments and investigates what is
|
||
necessary to perform the action. If the argument is a distribution
|
||
file name (recognized by embedded slashes), it is processed. If it is
|
||
a module, CPAN determines the distribution file in which this module
|
||
is included and processes that, following any dependencies named in
|
||
the module's Makefile.PL (this behavior is controlled by
|
||
I<prerequisites_policy>.)
|
||
|
||
Any C<make> or C<test> are run unconditionally. An
|
||
|
||
install <distribution_file>
|
||
|
||
also is run unconditionally. But for
|
||
|
||
install <module>
|
||
|
||
CPAN checks if an install is actually needed for it and prints
|
||
I<module up to date> in the case that the distribution file containing
|
||
the module doesnE<39>t need to be updated.
|
||
|
||
CPAN also keeps track of what it has done within the current session
|
||
and doesnE<39>t try to build a package a second time regardless if it
|
||
succeeded or not. The C<force> command takes as a first argument the
|
||
method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
|
||
command from scratch.
|
||
|
||
Example:
|
||
|
||
cpan> install OpenGL
|
||
OpenGL is up to date.
|
||
cpan> force install OpenGL
|
||
Running make
|
||
OpenGL-0.4/
|
||
OpenGL-0.4/COPYRIGHT
|
||
[...]
|
||
|
||
A C<clean> command results in a
|
||
|
||
make clean
|
||
|
||
being executed within the distribution file's working directory.
|
||
|
||
=item readme, look module or distribution
|
||
|
||
These two commands take only one argument, be it a module or a
|
||
distribution file. C<readme> unconditionally runs, displaying the
|
||
README of the associated distribution file. C<Look> gets and
|
||
untars (if not yet done) the distribution file, changes to the
|
||
appropriate directory and opens a subshell process in that directory.
|
||
|
||
=item Signals
|
||
|
||
CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
|
||
in the cpan-shell it is intended that you can press C<^C> anytime and
|
||
return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
|
||
to clean up and leave the shell loop. You can emulate the effect of a
|
||
SIGTERM by sending two consecutive SIGINTs, which usually means by
|
||
pressing C<^C> twice.
|
||
|
||
CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
|
||
SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
|
||
|
||
=back
|
||
|
||
=head2 CPAN::Shell
|
||
|
||
The commands that are available in the shell interface are methods in
|
||
the package CPAN::Shell. If you enter the shell command, all your
|
||
input is split by the Text::ParseWords::shellwords() routine which
|
||
acts like most shells do. The first word is being interpreted as the
|
||
method to be called and the rest of the words are treated as arguments
|
||
to this method. Continuation lines are supported if a line ends with a
|
||
literal backslash.
|
||
|
||
=head2 autobundle
|
||
|
||
C<autobundle> writes a bundle file into the
|
||
C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
|
||
a list of all modules that are both available from CPAN and currently
|
||
installed within @INC. The name of the bundle file is based on the
|
||
current date and a counter.
|
||
|
||
=head2 recompile
|
||
|
||
recompile() is a very special command in that it takes no argument and
|
||
runs the make/test/install cycle with brute force over all installed
|
||
dynamically loadable extensions (aka XS modules) with 'force' in
|
||
effect. The primary purpose of this command is to finish a network
|
||
installation. Imagine, you have a common source tree for two different
|
||
architectures. You decide to do a completely independent fresh
|
||
installation. You start on one architecture with the help of a Bundle
|
||
file produced earlier. CPAN installs the whole Bundle for you, but
|
||
when you try to repeat the job on the second architecture, CPAN
|
||
responds with a C<"Foo up to date"> message for all modules. So you
|
||
invoke CPAN's recompile on the second architecture and youE<39>re done.
|
||
|
||
Another popular use for C<recompile> is to act as a rescue in case your
|
||
perl breaks binary compatibility. If one of the modules that CPAN uses
|
||
is in turn depending on binary compatibility (so you cannot run CPAN
|
||
commands), then you should try the CPAN::Nox module for recovery.
|
||
|
||
=head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
|
||
|
||
Although it may be considered internal, the class hierarchy does matter
|
||
for both users and programmer. CPAN.pm deals with above mentioned four
|
||
classes, and all those classes share a set of methods. A classical
|
||
single polymorphism is in effect. A metaclass object registers all
|
||
objects of all kinds and indexes them with a string. The strings
|
||
referencing objects have a separated namespace (well, not completely
|
||
separated):
|
||
|
||
Namespace Class
|
||
|
||
words containing a "/" (slash) Distribution
|
||
words starting with Bundle:: Bundle
|
||
everything else Module or Author
|
||
|
||
Modules know their associated Distribution objects. They always refer
|
||
to the most recent official release. Developers may mark their releases
|
||
as unstable development versions (by inserting an underbar into the
|
||
visible version number), so the really hottest and newest distribution
|
||
file is not always the default. If a module Foo circulates on CPAN in
|
||
both version 1.23 and 1.23_90, CPAN.pm offers a convenient way to
|
||
install version 1.23 by saying
|
||
|
||
install Foo
|
||
|
||
This would install the complete distribution file (say
|
||
BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
|
||
like to install version 1.23_90, you need to know where the
|
||
distribution file resides on CPAN relative to the authors/id/
|
||
directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
|
||
so you would have to say
|
||
|
||
install BAR/Foo-1.23_90.tar.gz
|
||
|
||
The first example will be driven by an object of the class
|
||
CPAN::Module, the second by an object of class CPAN::Distribution.
|
||
|
||
=head2 ProgrammerE<39>s interface
|
||
|
||
If you do not enter the shell, the available shell commands are both
|
||
available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
|
||
functions in the calling package (C<install(...)>).
|
||
|
||
There's currently only one class that has a stable interface -
|
||
CPAN::Shell. All commands that are available in the CPAN shell are
|
||
methods of the class CPAN::Shell. Each of the commands that produce
|
||
listings of modules (C<r>, C<autobundle>, C<u>) returns a list of the
|
||
IDs of all modules within the list.
|
||
|
||
=over 2
|
||
|
||
=item expand($type,@things)
|
||
|
||
The IDs of all objects available within a program are strings that can
|
||
be expanded to the corresponding real objects with the
|
||
C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
|
||
list of CPAN::Module objects according to the C<@things> arguments
|
||
given. In scalar context it only returns the first element of the
|
||
list.
|
||
|
||
=item Programming Examples
|
||
|
||
This enables the programmer to do operations that combine
|
||
functionalities that are available in the shell.
|
||
|
||
# install everything that is outdated on my disk:
|
||
perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
|
||
|
||
# install my favorite programs if necessary:
|
||
for $mod (qw(Net::FTP MD5 Data::Dumper)){
|
||
my $obj = CPAN::Shell->expand('Module',$mod);
|
||
$obj->install;
|
||
}
|
||
|
||
# list all modules on my disk that have no VERSION number
|
||
for $mod (CPAN::Shell->expand("Module","/./")){
|
||
next unless $mod->inst_file;
|
||
# MakeMaker convention for undefined $VERSION:
|
||
next unless $mod->inst_version eq "undef";
|
||
print "No VERSION in ", $mod->id, "\n";
|
||
}

||
|
||
=head2 Methods in the four Classes
|
||
|
||
=head2 Cache Manager
|
||
|
||
Currently the cache manager only keeps track of the build directory
|
||
($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
|
||
deletes complete directories below C<build_dir> as soon as the size of
|
||
all directories there gets bigger than $CPAN::Config->{build_cache}
|
||
(in MB). The contents of this cache may be used for later
|
||
re-installations that you intend to do manually, but will never be
|
||
trusted by CPAN itself. This is due to the fact that the user might
|
||
use these directories for building modules on different architectures.
|
||
|
||
There is another directory ($CPAN::Config->{keep_source_where}) where
|
||
the original distribution files are kept. This directory is not
|
||
covered by the cache manager and must be controlled by the user. If
|
||
you choose to have the same directory as build_dir and as
|
||
keep_source_where directory, then your sources will be deleted with
|
||
the same fifo mechanism.
|
||
|
||
=head2 Bundles
|
||
|
||
A bundle is just a perl module in the namespace Bundle:: that does not
|
||
define any functions or methods. It usually only contains documentation.
|
||
|
||
It starts like a perl module with a package declaration and a $VERSION
|
||
variable. After that the pod section looks like any other pod with the
|
||
only difference being that I<one special pod section> exists starting with
|
||
(verbatim):
|
||
|
||
=head1 CONTENTS
|
||
|
||
In this pod section each line obeys the format
|
||
|
||
Module_Name [Version_String] [- optional text]
|
||
|
||
The only required part is the first field, the name of a module
|
||
(e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
|
||
of the line is optional. The comment part is delimited by a dash just
|
||
as in the man page header.
|
||
|
||
The distribution of a bundle should follow the same convention as
|
||
other distributions.
|
||
|
||
Bundles are treated specially in the CPAN package. If you say 'install
|
||
Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
|
||
the modules in the CONTENTS section of the pod. You can install your
|
||
own Bundles locally by placing a conformant Bundle file somewhere into
|
||
your @INC path. The autobundle() command which is available in the
|
||
shell interface does that for you by including all currently installed
|
||
modules in a snapshot bundle file.
|
||
|
||
=head2 Prerequisites
|
||
|
||
If you have a local mirror of CPAN and can access all files with
|
||
"file:" URLs, then you only need a perl better than perl5.003 to run
|
||
this module. Otherwise Net::FTP is strongly recommended. LWP may be
|
||
required for non-UNIX systems or if your nearest CPAN site is
|
||
associated with an URL that is not C<ftp:>.
|
||
|
||
If you have neither Net::FTP nor LWP, there is a fallback mechanism
|
||
implemented for an external ftp command or for an external lynx
|
||
command.
|
||
|
||
=head2 Finding packages and VERSION
|
||
|
||
This module presumes that all packages on CPAN
|
||
|
||
=over 2
|
||
|
||
=item *
|
||
|
||
declare their $VERSION variable in an easy to parse manner. This
|
||
prerequisite can hardly be relaxed because it consumes far too much
|
||
memory to load all packages into the running program just to determine
|
||
the $VERSION variable. Currently all programs that are dealing with
|
||
version use something like this
|
||
|
||
perl -MExtUtils::MakeMaker -le \
|
||
'print MM->parse_version(shift)' filename
|
||
|
||
If you are author of a package and wonder if your $VERSION can be
|
||
parsed, please try the above method.
|
||
|
||
=item *
|
||
|
||
come as compressed or gzipped tarfiles or as zip files and contain a
|
||
Makefile.PL (well, we try to handle a bit more, but without much
|
||
enthusiasm).
|
||
|
||
=back
|
||
|
||
=head2 Debugging
|
||
|
||
The debugging of this module is pretty difficult, because we have
|
||
interferences of the software producing the indices on CPAN, of the
|
||
mirroring process on CPAN, of packaging, of configuration, of
|
||
synchronicity, and of bugs within CPAN.pm.
|
||
|
||
In interactive mode you can try "o debug" which will list options for
|
||
debugging the various parts of the package. The output may not be very
|
||
useful for you as it's just a by-product of my own testing, but if you
|
||
have an idea which part of the package may have a bug, it's sometimes
|
||
worth to give it a try and send me more specific output. You should
|
||
know that "o debug" has built-in completion support.
|
||
|
||
=head2 Floppy, Zip, Offline Mode
|
||
|
||
CPAN.pm works nicely without network too. If you maintain machines
|
||
that are not networked at all, you should consider working with file:
|
||
URLs. Of course, you have to collect your modules somewhere first. So
|
||
you might use CPAN.pm to put together all you need on a networked
|
||
machine. Then copy the $CPAN::Config->{keep_source_where} (but not
|
||
$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
|
||
of a personal CPAN. CPAN.pm on the non-networked machines works nicely
|
||
with this floppy.
|
||
|
||
=head1 CONFIGURATION
|
||
|
||
When the CPAN module is installed, a site wide configuration file is
|
||
created as CPAN/Config.pm. The default values defined there can be
|
||
overridden in another configuration file: CPAN/MyConfig.pm. You can
|
||
store this file in $HOME/.cpan/CPAN/MyConfig.pm if you want, because
|
||
$HOME/.cpan is added to the search path of the CPAN module before the
|
||
use() or require() statements.
|
||
|
||
Currently the following keys in the hash reference $CPAN::Config are
|
||
defined:
|
||
|
||
build_cache size of cache for directories to build modules
|
||
build_dir locally accessible directory to build modules
|
||
index_expire after this many days refetch index files
|
||
cpan_home local directory reserved for this package
|
||
gzip location of external program gzip
|
||
inactivity_timeout breaks interactive Makefile.PLs after this
|
||
many seconds inactivity. Set to 0 to never break.
|
||
inhibit_startup_message
|
||
if true, does not print the startup message
|
||
keep_source keep the source in a local directory?
|
||
keep_source_where directory in which to keep the source (if we do)
|
||
make location of external make program
|
||
make_arg arguments that should always be passed to 'make'
|
||
make_install_arg same as make_arg for 'make install'
|
||
makepl_arg arguments passed to 'perl Makefile.PL'
|
||
pager location of external program more (or any pager)
|
||
prerequisites_policy
|
||
what to do if you are missing module prerequisites
|
||
('follow' automatically, 'ask' me, or 'ignore')
|
||
scan_cache controls scanning of cache ('atstart' or 'never')
|
||
tar location of external program tar
|
||
unzip location of external program unzip
|
||
urllist arrayref to nearby CPAN sites (or equivalent locations)
|
||
wait_list arrayref to a wait server to try (See CPAN::WAIT)
|
||
ftp_proxy, } the three usual variables for configuring
|
||
http_proxy, } proxy requests. Both as CPAN::Config variables
|
||
no_proxy } and as environment variables configurable.
|
||
|
||
You can set and query each of these options interactively in the cpan
|
||
shell with the command set defined within the C<o conf> command:
|
||
|
||
=over 2
|
||
|
||
=item o conf E<lt>scalar optionE<gt>
|
||
|
||
prints the current value of the I<scalar option>
|
||
|
||
=item o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>
|
||
|
||
Sets the value of the I<scalar option> to I<value>
|
||
|
||
=item o conf E<lt>list optionE<gt>
|
||
|
||
prints the current value of the I<list option> in MakeMaker's
|
||
neatvalue format.
|
||
|
||
=item o conf E<lt>list optionE<gt> [shift|pop]
|
||
|
||
shifts or pops the array in the I<list option> variable
|
||
|
||
=item o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>
|
||
|
||
works like the corresponding perl commands.
|
||
|
||
=back
|
||
|
||
=head2 urllist parameter has CD-ROM support
|
||
|
||
The C<urllist> parameter of the configuration table contains a list of
|
||
URLs that are to be used for downloading. If the list contains any
|
||
C<file> URLs, CPAN always tries to get files from there first. This
|
||
feature is disabled for index files. So the recommendation for the
|
||
owner of a CD-ROM with CPAN contents is: include your local, possibly
|
||
outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
|
||
|
||
o conf urllist push file://localhost/CDROM/CPAN
|
||
|
||
CPAN.pm will then fetch the index files from one of the CPAN sites
|
||
that come at the beginning of urllist. It will later check for each
|
||
module if there is a local copy of the most recent version.
|
||
|
||
Another peculiarity of urllist is that the site that we could
|
||
successfully fetch the last file from automatically gets a preference
|
||
token and is tried as the first site for the next request. So if you
|
||
add a new site at runtime it may happen that the previously preferred
|
||
site will be tried another time. This means that if you want to disallow
|
||
a site for the next transfer, it must be explicitly removed from
|
||
urllist.
|
||
|
||
=head1 SECURITY
|
||
|
||
There's no strong security layer in CPAN.pm. CPAN.pm helps you to
|
||
install foreign, unmasked, unsigned code on your machine. We compare
|
||
to a checksum that comes from the net just as the distribution file
|
||
itself. If somebody has managed to tamper with the distribution file,
|
||
they may have as well tampered with the CHECKSUMS file. Future
|
||
development will go towards strong authentication.
|
||
|
||
=head1 EXPORT
|
||
|
||
Most functions in package CPAN are exported per default. The reason
|
||
for this is that the primary use is intended for the cpan shell or for
|
||
oneliners.
|
||
|
||
=head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
|
||
|
||
To populate a freshly installed perl with my favorite modules is pretty
|
||
easiest by maintaining a private bundle definition file. To get a useful
|
||
blueprint of a bundle definition file, the command autobundle can be used
|
||
on the CPAN shell command line. This command writes a bundle definition
|
||
file for all modules that re installed for the currently running perl
|
||
interpreter. It's recommended to run this command only once and from then
|
||
on maintain the file manually under a private name, say
|
||
Bundle/my_bundle.pm. With a clever bundle file you can then simply say
|
||
|
||
cpan> install Bundle::my_bundle
|
||
|
||
then answer a few questions and then go out.
|
||
|
||
Maintaining a bundle definition file means to keep track of two things:
|
||
dependencies and interactivity. CPAN.pm (currently) does not take into
|
||
account dependencies between distributions, so a bundle definition file
|
||
should specify distributions that depend on others B<after> the others.
|
||
On the other hand, it's a bit annoying that many distributions need some
|
||
interactive configuring. So what I try to accomplish in my private bundle
|
||
file is to have the packages that need to be configured early in the file
|
||
and the gentle ones later, so I can go out after a few minutes and leave
|
||
CPAN.pm unattained.
|
||
|
||
=head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
|
||
|
||
Thanks to Graham Barr for contributing the firewall following howto.
|
||
|
||
Firewalls can be categorized into three basic types.
|
||
|
||
=over
|
||
|
||
=item http firewall
|
||
|
||
This is where the firewall machine runs a web server and to access the
|
||
outside world you must do it via the web server. If you set environment
|
||
variables like http_proxy or ftp_proxy to a values beginning with http://
|
||
or in your web browser you have to set proxy information then you know
|
||
you are running a http firewall.
|
||
|
||
To access servers outside these types of firewalls with perl (even for
|
||
ftp) you will need to use LWP.
|
||
|
||
=item ftp firewall
|
||
|
||
This where the firewall machine runs a ftp server. This kind of firewall will
|
||
only let you access ftp serves outside the firewall. This is usually done by
|
||
connecting to the firewall with ftp, then entering a username like
|
||
"user@outside.host.com"
|
||
|
||
To access servers outside these type of firewalls with perl you
|
||
will need to use Net::FTP.
|
||
|
||
=item One way visibility
|
||
|
||
I say one way visibility as these firewalls try to make themselve look
|
||
invisible to the users inside the firewall. An FTP data connection is
|
||
normally created by sending the remote server your IP address and then
|
||
listening for the connection. But the remote server will not be able to
|
||
connect to you because of the firewall. So for these types of firewall
|
||
FTP connections need to be done in a passive mode.
|
||
|
||
There are two that I can think off.
|
||
|
||
=over
|
||
|
||
=item SOCKS
|
||
|
||
If you are using a SOCKS firewall you will need to compile perl and link
|
||
it with the SOCKS library, this is what is normally called a ``socksified''
|
||
perl. With this executable you will be able to connect to servers outside
|
||
the firewall as if it is not there.
|
||
|
||
=item IP Masquerade
|
||
|
||
This is the firewall implemented in the Linux kernel, it allows you to
|
||
hide a complete network behind one IP address. With this firewall no
|
||
special compiling is need as you can access hosts directly.
|
||
|
||

||

|
||
|
||
=head1 BUGS
|
||
|
||
We should give coverage for _all_ of the CPAN and not just the PAUSE
|
||
part, right? In this discussion CPAN and PAUSE have become equal --
|
||
but they are not. PAUSE is authors/ and modules/. CPAN is PAUSE plus
|
||
the clpa/, doc/, misc/, ports/, src/, scripts/.
|
||
|
||
Future development should be directed towards a better integration of
|
||
the other parts.
|
||
|
||
If a Makefile.PL requires special customization of libraries, prompts
|
||
the user for special input, etc. then you may find CPAN is not able to
|
||
build the distribution. In that case, you should attempt the
|
||
traditional method of building a Perl module package from a shell.
