Free dynamic dns software for linux

DynDNS was originally founded to provide quality dynamic DNS services to the Internet and we continue to offer our free Dynamic DNS. In addition, we offer other services that might be of interest to a home user.
DynDNS is a focused and savvy DNS provider, specializing in dynamic DNS and complementary services. DynDNS is a private, internally funded and stable company.
We have no investors looking over our shoulders nor do we worry about our stock value. We run an efficient and profitable organization and pass these savings on to our customers. We are technologists that develop high quality services and our goal is to be the value provider of DNS services.
The free Dynamic DNS service allows you to alias a dynamic IP address to a static hostname in any of the many domains we offer, allowing your computer to be more easily accessed from various locations on the Internet. We provide this service, for up to five (5) hostnames, free to the Internet community.
The Dynamic DNS service is ideal for a home website, file server, or just to keep a pointer back to your home PC so you can access those important documents while youre at work.
Using one of the available third-party update clients you can keep your hostname always pointing to your IP address, no matter how often your ISP changes it. No more fumbling to find that piece of paper where you wrote down your IP address, or e-mailing all your friends every time it changes. Just tell them to visit yourname.dyndns.org instead!
Main features:
- Hostnames in 68 domains
- Wildcarding, allowing *.yourhost.dyndns.org to point to yourhost.dyndns.org

dynamic window manager or dwm is a dynamic window manager for X11.
As founder and main developer of wmii I came to the conclusion that wmii is too clunky for my needs. I dont need so many funky features and all this hype about remote control through a 9P service, I only want to manage my windows in a simple, but dynamic way.
wmii never got finished because I listened to users, who proposed arbitrary ideas I considered useful. This resulted in an extreme CADT development model, which was a mistake. Thus the philosophy of dwm is simply to fit my needs (maybe yours as well). Thats it.
Main features:
- dwm has no Lua integration, no 9P support, no editable tagbars, no shell-based configuration, no remote control, and comes without any additional tools like printing the selection or warping the mouse.
- dwm is only a single binary, its source code is intended to never exceed 2000 SLOC.
- dwm is based on tagging and dynamic window management (however simpler than ion, wmii or larswm). It manages windows in tiling and floating modes. Either mode can be applied dynamically, depending on the application in use and the task performed.
- dwm doesnt distinguishes between layers, there is no floating or tiled layer. Wether the clients of currently selected tag are in tiled mode or not, you can re-arrange all clients on the fly. Popup- and fixed-size windows are treated floating, however.
- dwm is customized through editing its source code, that makes it extremely fast and secure - it does not process any input data which hasnt been known at compile time, except window title names and status text read from standard input. You dont have to learn Lua/sh/ruby or some weird configuration file format (like X resource files), beside C to customize it for your needs, you only have to learn C (at least editing header files).
- Because dwm is customized through editing its source code, its pointless to make binary packages of it. This keeps its userbase small and elitist. No novices asking stupid questions.
- dwm uses 1-pixel borders to provide the maximum of screen real estate to clients. Small titlebars are only drawn in front of unfocused clients.
- dwm reads from standard input to print arbitrary status text (like the date, load, battery charge). Thats much simpler than larsremote, wmiir and what not...
- It can be downloaded and distributed under the conditions of the MIT/X Consortium license.
- Optionally you can install dmenu to extend dwm with a wmii-alike menu.
Enhancements:
- This release contains certain major bugfixes, especially regarding banning/unbanning client windows.

tinydyndns is a simple but powerful dynamic DNS solution that uses djbdns. tinydyndns cooperates with the djbdns package to publish dynamic IP addresses authenticated through POP connections.

On successfully authenticated POP connections, the tinydyndns-update program manipulates tinydns constant database "data.cdb" directly without rebuilding it; this makes the dynamic DNS solution use very few system resources.

Using a POP service for authentication saves the work for installing special client software, since POP clients are available for every common network-aware operating system. To provide the DNS and POP service, tinydyndns cooperates with djbdns, qmail, and cvm.

Dynamic Image Resize Wizard is a free PHP script that enables your visitors to re-size their images quickly, efficiently and on-the-fly.
The user just enters the URL of the image they wish to resize, and the length they wish the image to be, and the Wizard does the rest.You can use it for your own site or for your site visitors, and its easy to integrate in with other scripts.
Main features:
- Dynamic Image Resize Wizard is easy to install. Just unzip and upload, or if youre using it on a local server, just unzip!
- The Dynamic Image Resize Wizard interface is super simple and the instructions are easy to understand.
- The script is easy to integrate in with other site components.
- Perfect for resizing an image without getting that annoying grainy look that comes from trying to shrink an image using just HTML.

Dynamic Probe Class Library (DPCL) is an object-based C++ class library that provides the necessary infrastructure to allow tool developers and sophisticated tool users to build parallel and serial tools through technology called dynamic instrumentation.
Dynamic Probe Class Library takes the basic components needed by tool developers and encapsulates them into C++ classes. Each of these classes provide the member functions necessary to interact and dynamically instrument a running application with software patches called probes.
Dynamic instrumentation provides the flexibility for tools to insert probes into applications as the application is running and only where it is needed.
Enhancements:
- This version is a minor update to DPCL that fixes a couple problems that have been reported since the v3.4.2 release

dyndnsupdate is a tool for keeping dynamic DNS hosts up to date. It simply processes the URLs in dyndns.hosts config file (sends a HEAD request via HTTP). No biggie, but it works.
Put dyndns.hosts in /etc and run dyndnsupdate from an init-script. That way youll be sure that your dyndns hosts are up to date within minutes after rebooting and perhaps changing IP address.
On my Debian box Ive put dyndns.hosts in /etc and linked to dyndnsupdate from etc/rc2.d, like this:
ln -s /usr/bin/dyndnsupdate /etc/rc2.d/S91dyndnsupdate
That will make sure that dyndnsupdate is up and run when rebooting.
Furthermore, it can be encouraged to run dyndnsupdate as a cron-job as well, in case your server should be up for more than a month, since most dyndns providers requires you to update at least once a month.
This can be done by adding the following line to your crontab:
15 5 */25 * * dyndnsupdate -s
Thatll make cron run dyndnsupdate every 25 days at 5:15AM and -s makes the script output nothing (unless errors are encountered) so youll be rid of the annoying exit status mails from cron.
Enhancements:
- Added win32/ for windows builds with exerb.
- added win32/LICENSE
- added win32/README

TinyDYN provides a package for creating and using dynamic DNS services.
TinyDYN is a package of client and server software for operating dynamic DNS services.
It enables anyone to run dynamic DNS services using strong authentication or to be a client of someone using TinyDYN as a dynamic IP management system.
The clients can communicate directly by UDP with the server, by email, or by any other transport the admin can imagine, as the mechanism is quite straightforward.
The services use strong authentication via GnuPG, and is designed to work with djbdnss tinydns for name service.
Because TinyDYN uses GPG instead of shared passwords, you will have to create a GPG sign-only key for sending your requests to your dynamic DNS service provider.
This keyring (kept in /etc/tinydyn/gnupg/) contains secret information that must be protected in the same way that a configuration file containing a password would be.
Enhancements:
- tinydyn now runs cleanly under daemontools
- Logging output was cleaned up to make it more sensible
- service/ files are provided for daemontools
- Numerous error detection bugs replaced due to syntax error
