XAO::Web is a Perl module for XAO Web Developer, dynamic content building suite.
XAO::Web is a part of XAO open source web services suite. It allows to build dynamic web content using data, templates and external input.
The distinguishing feature of XAO::Web is in its modular design where almost every aspect of functionality can be altered and alterations can be re-used. No complex code is embedded in the templates which allows to upgrade code and templates separately or maintain multiple visual representations of the same functionality at the same time.
Aside from that most interesting features of XAO::Web are:
- Perl code is not mixed with templates. Templates can be normal HTML files if no processing is required.
- A specific site can replace or modify standard XAO::Web objects if required by overriding or extending their methods. You do not need to re-implement entire object to make a site specific change.
- In case of system object upgrade or bug fix there is no need to alter site-specific changes normally.
- Site can create any extension objects or embed third-party extensions as well.
- One server can serve arbitrary number of XAO::Web sites each with however extended functionality without creating any conflicts. That includes different modifications to the system objects for different sites.
- Not limited to Web environment, allows to build any dynamic content -- content of mail messages or reports for instance.
- Works with CGI or mod_perl (mod_perl is recommended for production grade sites).
If used in mod_perl mode improves performance by using caching of configuration, parsed templates, database handlers and so on.
- XAO::Web is by default integrated with XAO::FS (see XAO::FS) as a database layer, but this is not a requrement -- if for any reason a different database must be used for a site it can be easily and gracefully achieved.
- Hosting providers can allow their customers to build very complex sites without allowing them to execute arbitrary code, by allowing to modify only templates.

Web Ping is a program for testing your internet connection.

Web Ping is a simple application to test an internet connection to a perticular site. I created this application after my work moved locations and half our network stayed in the old building and the other half moved with us to the new location.

A flaky (significant point) VPN was set up to keep the two connected. Since a couple of the unmoved servers were of interest to me, I keeped checking to see if they were still accessable with the ping command before doing any serious work with them.

A quick and pathetic Google resulted in no other program that meet my needes, so I wrote one.

Insted of doing an actual network ping, Web Ping tests a connection by downloading a web page on a given server. The size of the page and time are stored in memory and the times are graphed. In this way, sites that block network a ping can still be tracked.

Web Ping also keeps track of the largest and smallest download times per session and also tracks the max and min values currently on the graph. Times of interest are graphed in a color which represents if it is a max or a min. (see figure one). The history tab also lists all the max values as they have been recevied.

A running average is also calculated with each download. The files downloaded are not processed or stored in any way. This prevents any security problems that can normaly happen in a web browser enviroment. The only two pecies of information retained about a downloaded file is the size and time.

Usage:

There are two ways to use Web Ping, GUI or CLI mode. The simplest of the two modes is CLI. Web Ping can be started in CLI mode by passing a url to the jar file in a command line interface like this: "java -jar WebPing.jar http://localhost". Web Ping will automaticly start getting statistics on the requested url, printing results to the screnn.

To quite, press q and then then ENTER key. CLI allows the user to Most people will probably want to use the GUI mode which has a history graph and allows the user to start and stop the session.

The best way to run Web Ping is in GUI mode. GUI mode allows the user start and stop the ping process at will and to change the site that is pinged. Users can also see more information about about the history of the pings and view max values and min values easily. There are three tabs on the top of the page, the first is the application, second is the history list, and the last give information about the application.

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.

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.
