Free webs software for linux

Web Perl module contains a set of useful routines for many webworking purposes.

This module was primarily made for UNIX/Linux-Systems. Parts of it cannot be used on other systems. E.g. the procedures for file locking demand systems that can use symlinks. If you use the modul on systems where symlinks cannot be used, fatal errors may happen.

ABSTRACT

This perl module serves users with several useful routines for many purposes, like generating webpages, processing CGI scripts, working with XML datafiles and net-connections. It also uses own variants of routines, that was invented first in the famous libraries CGI.pm and cgi-lib.pl.

INSTALLATION

If you dont have sufficient privileges to install web.pm in the Perl library directory, you can put web.pm into some convenient spot, such as your home directory, or in cgi-bin itself and prefix all Perl scripts that call it with something along the lines of the following preamble:

use lib /home/myname/perl/lib;
use web;

NLock

This routine allows to set a filelock across NFS-boundaries. The common used perl-routine flock() fails at this point, so this routine is a useable alternative for bigger file-systems. It uses the modular functions link() and unlink() to mark a file locked. In addition to this, it also gives the locked file a counter: A file that is locked for more than $web::MAX_LOCKTIME seconds will be freed by the next process that calls NLock() on this file. A calling process gets either 0 or 1 as a return value, where 1 is returned if the file-locking was successful. 0 is returned only if the process waits for more than $web::MAX_WAITLOCK seconds or if symlink() fails.

Example 1:

$filename = "data.txt";
NLock($filename);
open(f1,"$filename");
# do something
close f1;
NUnlock($filename);

Example 2:

#!/local/bin/perl5
use web;

$stat= &NLock("jump.pl");
print "Lock: stat= $statn";
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
sleep 8;
$stat= &NLock("jump.pl");
print "Lock this file again: stat= $statn";
$stat= &NUnlock("jump.pl");
print "Unlock: stat= $statn";
exit;

web-chpass utility allows users to change their account password through the web. This package was written with security and flexibility as the primary concerns--and in that order. It runs on systems that use PAM to manage user authorizations. At this time, it has been tested only on Red Hat 7.2.
The web pages produced are completely customizable. The chpass.cgi utility contains no HTML. Instead, web pages are produced from an external template.
"Bad password" checking can be optionally enabled. As distributed, the web page template offers the user a choice, with these checks enabled by default.
This package includes several components that may be useful for other applications. The nipasswd utility allows non-privileged programs to authenticate users and change passwords in a
Enhancements:
- This release fixes a bug with previously unexpected "Password changed" notices from PAM on SuSE 10.1.

web-nsupdate is a web-based dynamic DNS update utility.

The web-nsupdate package provides a simple, web-based facility for clients to send dynamic DNS updates. Clients are typically DHCP hosts, such as a Linux system acting as a gateway for residential broadband service.

The client sends a simple web request (such as with the wget(1) or lynx(1) commands) to the web-nsupdate service to register their host request.

This package has been tested on a server with the following Debian packages:

* bind9 (ver 9.2.4-1)
* apache2 (ver 2.0.54-5)
* php4 (ver 4.3.10-16)

BE ADVISED: Its a pain in the butt to configure BIND to do dynamic DNS. You are going to need to do that to make "web-nsupdate" work. These instructions describe that process, so follow carefully. I *strongly* urge you to review the dnssec-keygen(8) and nsupdate(8) man pages first, so you can get some idea of what we are trying to accomplish.

Installation Instructions:

1. Copy the "web-nsupdate" files to a location such as
"/usr/local/lib/web-nsupdate". It is OK to install somewhere else,
just adjust the following directions accordingly.

2. Generate a TSIG key that "web-nsupdate" will use to authenticate
itself to the DNS server.

SECURE THIS KEY! Do not leave readable copies around. This key can
be used to make changes to DNS records managed by "web-nsupdate".

Here are the steps to generate the key:

cd /usr/local/lib/web-nsupdate
/usr/sbin/dnssec-keygen -a HMAC-MD5 -b 512 -n HOST web-nsupdate
chmod 440 Kweb-nsupdate*
# Below, adjust "www-data" to the GID your web server runs under.
chgrp www-data Kweb-nsupdate*

3. Setup the "web-nsupdate" definitions file, starting with the provided
sample. This file needs to be secured, to protect the client passwords
from being revealed.

cd /usr/local/lib/web-nsupdate
cp nsupdate-defs.php.sample nsupdate-defs.php
chmod 640 nsupdate-defs.php
# Below, adjust "www-data" to the GID your web server runs under.
chgrp www-data nsupdate-defs.php
vi nsupdate-defs.php

4. Verify that "nsupdate.php" has the correct path to the "nsupdate-defs.php"
file.

vi nsupdate.php
# Check the require_once() statement near the top.

5. Symlink the update script into your web site.

# Below, adjust "/var/www/nsupdate.php" to a location in your web server.
ln -s /usr/local/lib/web-nsupdate/nsupdate.php /var/www/nsupdate.php

At this point, the "web-nsupdate" front-end is configured. Now to
configure the nameserver back-end.

6. Assuming you dont already have a place for nameserver keys, create
a new file called "named.keys" that contains the TSIG key that
"web-nsupdate" will use. The file will look something like:

key web-nsupdate {
algorithm HMAC-MD5;
secret "jzzoMR4ocgZGq5pQho2Pr5r9DDHT4lWK8QO09cpvVtpvHqaUdzktBs1DHCslpPR8PwXU3ni8zjST/5FxEwg44Q==";
};

Replace the "secret" value show above with the key in the
"Kweb-nsupdate.+157+nnnnn.private" file you generated in step 2.

7. Install the "named.keys" file to the directory where your "named.conf"
resides. This file needs to be secured, to protect your namesever
from unauthorized updates.

If your "named.conf" directory is "/etc/bind", do:

# Below, adjust /etc/bind to directory where named.conf lives.
mv named.keys /etc/bind/named.keys
chmod 400 /etc/bind/named.keys
# Below, adjust "bind:bind" to the UID:GID your nameserver runs under.
chown bind:bind /etc/bind/named.keys

8. Add a line to your "named.conf" that says:

include "named.keys";

9. Modify your "named.conf" to list each host that web-nsupdate will
be updating. If, for example, you want to allow dynamic updates
from hosts "host1.example.com" and "host2.example.com", then modify
the "example.com" stanza in "named.conf" and add two lines:

zone "example.com" {
type master;
.
.
.
# add the lines below, one per host in thie zone
update-policy {
grant web-nsupdate. name host1.example.com. A;
grant web-nsupdate. name host2.example.com. A;
};
};

10. Test the update capability. Point your web browser to the installed
"nsupdate.php" script. This should bring up a form for manual
entry. Submit your entry, and verify the update was successful.

Web::Scaffold is a Perl module to build minimalist fancy web sites.

SYNOPSIS

use Web::Scaffold;

Web::Scaffold::build(%specs,%pages);

Web::Scaffold is a module that allows you to easily and quickly build a fancy web site with drop down menus an a variable number of columns. This is accomplished with a simple specification and a series of minimal html page includes that are written in very basic html.

In its simplest form, your web will have the following structure:

pages/ contains minimalist html pages
ws_sitemap/ [optional] contains sitemap in google xml format
NOTE: link this into public_html
public_html/ contains the index page and
any non Web::Scaffold pages
images/ contains web site images
lib/ contains javascript library(s)

The index pages requires Server Side Includes (SSI) and is as follows:

< html >
< !-- page name "index.shtml"
place your comments, revision number, etc... here
-- >
< !--#exec cmd="./pages.cgi" -- >
< /body >
< /html >

Alternatively, you can use the included pages.cgi script as an example to build your own more sophisticated cgi or mod_perl application.

SVN::Web provides a Web interface to Subversion repositories.
You can browse the tree, view history of a directory or a file, see whats changed in a specific revision, track changes with RSS, and also view diffs.
SVN::Web also tracks the branching feature (node copy) of Subversion, so you can easily see the relationship between branches.
Enhancements:
- The "reposparent" functionality was inadvertently broken in 0.50.
- This release fixes it.

Web Bench is very simple tool for benchmarking WWW or proxy servers. Uses fork() for simulating multiple clients and can use HTTP/0.9-HTTP/1.1 requests.
This benchmark is not very realistic, but it can test if your HTTPD can realy handle that many clients at once (try to run some CGIs) without taking your machine down.
Displays pages/min and bytes/sec. Can be used in more aggressive mode with -f switch.
Enhancements:
- allow building with both Gnu and BSD make
