fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.

Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.

If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Problem and Issues:

With a large a number of IP addresses in use, its becomes more and more time consuming to check on which IP addresses are actively in use, and which critical machines (routers, bridges, servers, etc) are reachable. One example is we have a program which goes through all of our routers arp caches looking for IP addresses that are in use. After finding a list of IP addresses that arent in any arp caches fping can then be used to see if these IP addresses really arent being used, or are just behind the routers. Checking 2500 hosts (99% of which are unreachable) via ping can take hours.

fping was written to solve the problem of pinging N number of hosts in an efficient manner. By sending out pings in a round-robin fashion and checking on responses as they come in at random, a large number of hosts can be checked at once.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Domain Auditor project was written to audit and track accounts within a domain. This tool uses LDAP queries to a definable Active Directory server to find various definable classes of accounts.
Initially it will operate interactively, but capabilities may be added in the future to automate functions (i.e. generate reports on a scheduled basis). The installation script handles most installation chores, so setup is very straightforward.
The tool is beta status at this time, but is in being used to generate SOX reports for my employer.
Main features:
- Reports - This function will display a list of defined reports, when invoked it will generate a list of accounts from AD (via LDAP queries) the results returned will depend on what you have defined for the filter for any particular report class under Sysadmin
- Sys Admin - This function will allow you to changes the system settings for LDAP server and port, base DN, Bind DN, username and password, and the database settings (mySQL only at this time). You may also add the report class definitions and their matching LDAP filters within this module
- User Admin - This screen is used to define users for the system and their rights. Usernames are used as the primary value, and entered values are validated via LDAP queries
- Audit Logs - The system logs all changes to the information stored and this page will allow you to review the data from these logs

GlassBarMini is an adaptation of the theme Ive been using for a couple of years now. My goal for a system monitor is one that will always be visible, regardless of what Im doing. This theme is sized such that you can position it at the top of the screen, and it will fit unobtrusively over the title bar--space that isnt being used anyway.

To get this theme to work with your network setup, youll need to replace every instance of "eth0" with your network device (eth1, ath0, wlan1, etc.) in the GlassBarMini.theme file.

I had to set window-specific settings in KDE to keep the theme on top of other windows--there might be a better way to do this, but I dont know it ;)

The new GlassBarMini theme is derived from artwork from the original GlassHUD/GlassHUDX monitors and CaceKs GlassPlayer. Ive also included the background and theme file from the theme that Ive used previously, in case anyone prefers that.

Wide Area Link Emulator enables you to set and test various parameters of a WAN access link (also known as a bottleneck link) before testing on a fully-functional network.

Any ISP has a high bandwidth LAN (of the order of tens of Mbps, e.g. Ethernet) and a WAN access link with relatively low speeds (of the order of a few Kbps to a few Mbps). To be able to evaluate the ISPs performance, actual tests will have to be conducted on a live, fully functional network. This would imply enabling certain features in communication equipment which could be detrimental to the proper functioning of a commissioned network. To address such a problem of being able to characterize/quantify the network operation in terms of its performance with respect to various parameters, a test-bed emulating the ISPs connectivity to the Internet would be an ideal solution.

An important factor in setting up such a test-bed, is emulating the WAN Access Link. Using complex hardware is costly. Such a link can however be easily implemented by emulating the scenario on popular physical technology such as Ethernet. By changing the TCP/IP stack on a Personal Computer, the rate at which packets are injected into the network can be controlled and other necessary features can easily be added.

WALE was implemented in 2 phases and the first version can emulated bandwidths up to 8Mbps and uses FIFO queues with drop-tail.

WALE v2 can emulate bandwidths of up to 80Mbps(a 10-fold improvement over version 1) due to the stripped down version of Micro-second resolution timer being used in the Linux kernel. WALE also implements differentiated services are recommended by IETF. A hash-based packet classifier is used to classify packets into one of 3 queues (Expedited Forwarding, Assured Forwarding and Best Effort). A simple priority scheduling has been implemented between the queues.

Version 2 has been implemented in the Generic Device Layer of the Linux Kernel. The kernel version is 2.2.19. WALE2 kernel patch can be downloaded here. An ncurses based front end has been implemented for setting and viewing various parameters of the bottleneck link.

chngpwd is a secure wrapper to change user passwords another user in a PAM-enabled system.

chngpwds main use is as a wrapper for other interfaces to communicate with the user (e.g., Web interface).

It was build with security in mind, so there should not be any security bugs or holes opened by it (But you should check by your self before using it).

It requires: Authen::PAM from CPAN and Sys::Syslog (your perl distribution should have it already).

The main use for this is as a wrapper for changing password securily (e.g. from a web interface). So the cgi or whatever is being used doesnt need to deal with this issues (and run the cgi as suid root).

The script is rich in error messages and exit codes, so it is easy to track down errors, misconfiguration and abuses.

Also, on some critical circunstances it will try to mail the admin in a unknown event. Everything that it does is also logged to Syslog.

As it uses PAM to change passwords, it should work on any PAM aware system (almost all Linux distributions, Solaris and at some extend HP-UX). I just tested it on Linux (Conectiva Linux and Debian btw).

Mplinuxman is a manager for the MPMan F60 portable MP3 player. This player has PC connectivity through USB and it comes bundled with Windows manager software, which has its limitations. The main one being it cant be used on Linux! Well now you can, Mplinuxman uses Linux kernel support for USB devices, and can be set up for hot swapping. If you have an MPMan F60 its time to wipe quit windows and use Mplinuxman on linux.
Main features:
- Easy to use interface using GTK 2
- Downloading, uploading files to and from the player, deleteing,re-ordering files on the player
- Playlist loading/saving and can create a random list of files to fit on the players available memory
- Hot plugging, Mplinuxman can be set to start/stop when you connect/disconnect the MPMan
- Lets you upload MP3s from the player to your PC unlike the Windows version
- Uses default Linux console font to display ID3 tags on the player!
Enhancements:
- Added support for building on Mac OS X, thanks to Kris
- Added Japanese (by Shimada) and German (by Thomas) translations
- Added format for camera, to format the SMC for other devices, eg camera and usb card reader. (patch by Tholom)
- Support for MP-F55, changed the find devices routine to find F55
- Decreased playlist/directory loading times.

Interbench is benchmark application is designed to benchmark interactivity in Linux.
Interbench is designed to measure the effect of changes in Linux kernel design or system configuration changes such as I/O scheduler, cpu and filesystem changes and options. With careful benchmarking, different hardware can be compared.
What does it do?
It is designed to emulate the cpu scheduling behaviour of interactive tasks and measure their scheduling latency and jitter. It does this with the tasks on their own and then in the presence of various background loads, both with configurable nice levels and the benchmarked tasks can be real time.
How does it work?
First it benchmarks how best to reproduce a fixed percentage of cpu usage on the machine currently being used for the benchmark. It saves this to a file and then uses this for all subsequent runs to keep the emulation of cpu usage constant.
It runs a real time high priority timing thread that wakes up the thread or threads of the simulated interactive tasks and then measures the latency in the time taken to schedule. As there is no accurate timer driven scheduling in linux the timing thread sleeps as accurately as linux kernel supports, and latency is considered as the time from this sleep till the simulated task gets scheduled.
Each benchmarked simulation runs as a separate process with its own threads, and the background load (if any) also runs as a separate process.
Enhancements:
- This release adds options to select benchmarked loads, manpages, and documentation updates.
