WPKG can add great value to your Samba or Active Directory setup, as it allows to perform software installation, updates, removal etc. on your workstations. It features dependencies and there is a windows service wich does all this on machine start, user logons can be delayed until wpkg has finished its work.

It is also possible to execute custom scripts on your workstations, like synchronizing time, setting printers, changing permissions or adding registry entries (basically, some of the things you would do with Active Directory and Group Policy / GPO).

Basically it is a set of XML files and a javascript program. There is a web-gui for package/machine management available at http://wpkg.linuxkidd.com/.

I like to use this to throw together nice web frontends for the PHBs to look at stats & stuff. It's pretty simple to use, interfaces easily to a database--very useful for the sorts of sysadmin-plus stuff I tend to do.

LEO is an outliner, but by implementing a visually compelling directed acyclic graph (DAG) instead of a strict tree, it allows one to present multiple aspects of structure. Some "branches" of the graph can generate source code, others configuration files, others comprise documentation which includes analogs of "hard links" to portions of the code or configuration; various aspects of the subject can be pulled out and collected into coherent subsets independent of each other's structure.

Example: sendmail.mc generated by one tree, other trees within the graph contain source for the various .m4 files, while a documentation tree contains text but also nodes from the various files making the specific implementation immediately available for modification along with the documentation.

Ever been disconnected from your ssh session while in the middle of something? Ever wished there was a way to reconnect to that lost ssh session? Screen is for you..

Screen is a full-screen window manager that multiplexes a physical terminal between several processes. In fact, when you execute screen, you can imagine that you turned on another screen to the server that you're working on. You then execute your process on that virtual screen, detach your connection from it and return, whenever you please, to that screen in order to continue working.

Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows. When screen is called, it creates a single window with a shell in it (or the specified command) and then gets out of your way so that you can use the program as you normally would. Then, at any time, you can create new (full-screen) windows with other programs in them (including more shells), kill the current window, view a list of the active windows, turn output logging on and off, copy text between windows, view the scrollback history, switch between windows, etc. All windows run their programs completely independent of each other. Programs continue to run when their window is currently not visible and even when the whole screen session is detached from the users terminal.

FastSum is an extremely fast MD5 hash utility for your file integrity control. The high accuracy and speed attains through the use of a well-known and time-proven cryptographic MD5 algorithm. As a matter of fact, FastSum is a Windows MD5 hash checker. You do not have to be afraid of these unintelligible words, all you have to know is - how to run FastSum.

PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator. It is written and maintained primarily by Simon Tatham.

The latest version is beta 0.58.
