Free perl script software for linux

Game Server Startup Script project is a startup script to manage dedicated game servers like Quake3.
Game Server Startup Scripts is a startup script to manage a wide variety of Linux dedicated game servers. It can start/stop/restart/fix dedicated game servers like Quake3, Half Life, Tribes 2, UT2K4, BF1942 and others.
It uses qstat through cron to validate that a game is running as expected. If a game is not running as expected, the game is automatically restarted from the script through cron.
GSSS was written becuase I wanted a way to start up a variety of games in a standard way. Then I also wanted to make sure the games stayed running even after a crash.
So I wrote this perl script. It will start games and through a cron job make sure they stay running. If you have qstat installed it can also verify the game is running like it is suppose to be and not in some strange state where no one can play.
If the game is running but unresponsive, it kills it and starts it again. You can also stop running games cleanly as well.
Games supported by "Game Server Startup Script":
- Quake2
- Quake3
- RTCW
- Half Life
- Unreal
- UT2K3
- UT2K4
- Tribes 2
- NWN
- BF1942
- ET
Enhancements:
- Very minor changes, minor readme changes, clean up

For some problems, particularly in the presentation layer, thinking of the solution as a webpage that can run perl is more natural than thinking of it as a perl script that can print a webpage.

It's been done before, but this module is simple. The source code is compact: one file and less than 2k of code. Simply put: if you can do it in Perl, you can do it in Markup:Perl, only without all the print statements, heredocs and quotation marks.

Requirements:

• Perl

GPGlist project is a Perl script to implement gpg encrypted alias lists in a mail server.

GPGlist is a Perl script to implement gpg encrypted alias lists in a mail server such as Sendmail or Postfix.

It uses one XML config file to store information about lists. It backs up messages if an error occurs, and sends out error messages to the sender of the mail.

You can decide whether or not a list only accepts encrypted messages.

JPPS (Jeb Perl Ping Stats) is a Perl script which extracts statistics from the output generated by the ping command.

Here is an example of how the script works:
#ping -c 50 ovh.fr > ping.log
#./ping.pl ping.log
-- Ping of ovh.fr (213.186.33.6) (file ping.log) --
Ping mini: 37.795ms at ping number 20
Ping maxi: 79.198ms at ping number 47
Average: 44.18596ms
Ping lost: 0 of 50 (0%)

Jifty::Script::Help is a Perl module to show help.

OPTIONS

Optionally help can pipe through a pager, to make it easier to read the output if it is too long. For using this feature, please set environment variable PAGER to some pager program. For example:

# bash, zsh users
export PAGER=/usr/bin/less

# tcsh users
setenv PAGER /usr/bin/less

help_base

Jiftys help system also looks in Jifty::Manual and the subdirectories for any help commands that it cant find help for.

ModPerl::PackageRegistry is a Perl module to map URIs to perl package namespaces.

SYNOPSIS

Apache:

< Location /dynamic >
SetHandler perl-script
PerlResponseHandler ModPerl::PackageRegistry
PackageNamespace MyWebsite::pages
PackageBase /dynamic
PackageIndex index
PackageHandler ->page
< /Location >

Perl:

package MyWebsite::pages::index;

use strict;
use warnings;

use Apache2::RequestRec ();
use Apache2::Const q(OK);

return 1;

sub page {
my($class, $r) = @_;
$r->do_stuff();
return OK;
}

This mod_perl2 handler allows you to directly map a path in your apache 2.x server to a package namespace in perl. When the handler is invoked, it transforms the URI requested into the name of a perl module, and if that module is found, executes the handler specified by the PackageHandler directive.

zeMail is a minimalist webmail package written in Mason. It implements the basic features one would expect from an IMAP mail client, displaying folder and message contents, handling attachments and allowing you to move, mark and purge your messages.
zeMail package is written in plain HTML, and uses JavaScript only to reduce the click count, it will work perfectly with scripting disabled. Compared to the modern AJAX trend, this web mail package is designed to work everywhere.
Installation:
Download and unpack the tarball. Copy the directory lib/Zentus into your Perl inc. path (/usr/local/lib/perl/5.8.4 on Debian).
Copy the contents of mason/ into the desired subdirectory of your Apache htdocs directory or virtual host. Then add the following to your httpd.conf:
PerlModule Zentus::Mail::Connection
PerlModule Zentus::Mail::AttachmentHandler
PerlModule HTML::Mason::ApacheHandler
PerlModule Apache::Session::File
PerlModule Text::Autoformat
< Location / >
SetHandler perl-script
PerlHandler HTML::Mason::ApacheHandler
DirectoryIndex folder
< /Location >
< Location /attachment >
SetHandler perl-script
PerlHandler Zentus::Mail::AttachmentHandler
< /Location >
< LocationMatch "(/icons|/images|.ico|.html|.txt)" >
SetHandler default-handler
< /Location >
< LocationMatch "(autohandler|dhandler|.inc)" >
SetHandler None
< /Location >
This code segment can be added as-is if you intend to devote a VirtualHost to zeMail, otherwise prefix a directory name in the < Location > and < LocationMatch > tags.
Now install the necessary Perl modules from CPAN:
cpan -i HTML::Mason # or deb: libhtml-mason-perl
cpan -i Apache::Session # or deb: libapache-session-perl
cpan -i DB_File::Lock # or deb: libdb-file-lock-perl
cpan -i Text::Autoformat # or deb: libtext-autoformat-perl
cpan -i HTML::FormatText # or deb: libhtml-format-perl
cpan -i Net::IMAP::Simple # (needed really in name only,
# to be removed in next release)
You may have to create the temporary directory manually:
mkdir /tmp/zemail
chown www /tmp/zemail
Now restart your Apache and your are good to go.
Enhancements:
- Supports all basic forms of email, strips out MIME, displays attached images inline, and lets you download the rest.

mod_speedycgi speeds up perl scripts by running them persistently.

SpeedyCGI is a way to run perl scripts persistently, which can make them run much more quickly. A script can be made to to run persistently by changing the interpreter line at the top of the script from:

#!/usr/bin/perl

to
#!/usr/bin/speedy

After the script is initially run, instead of exiting, the perl interpreter is kept running. During subsequent runs, this interpreter is used to handle new executions instead of starting a new perl interpreter each time. A very fast frontend program, written in C, is executed for each request. This fast frontend then contacts the persistent Perl process, which is usually already running, to do the work and return the results.

By default each perl script runs in its own Unix process, so one perl script cant interfere with another. Command line options can also be used to deal with programs that have memory leaks or other problems that might keep them from otherwise running persistently.

SpeedyCGI can be used to speed up perl CGI scripts. It conforms to the CGI specification, and does not run perl code inside the web server. Since the perl interpreter runs outside the web server, it cant cause problems for the web server itself.

SpeedyCGI also provides an Apache module so that under the Apache web server, scripts can be run without the overhead of doing a fork/exec for each request. With this module a small amount of frontend code is run within the web server - the perl interpreters still run outside the server.

SpeedyCGI and PersistentPerl are currently both names for the same code. SpeedyCGI was the original name, but because people werent sure what it did, the name PersistentPerl was picked as an alias. At some point SpeedyCGI will be replaced by PersistentPerl, or become a sub-class of PersistentPerl to avoid always having two distributions.
