Kernel Version Monitor is a Superkaramba theme that creates a widget displaying the current version information of the Linux kernel as put forth by the kernel.org RSS feed here: http://kernel.org/kdist/rss.xml . Kernel Version Monitor uses the Tux icon from the nuoveXT icon theme found at http://nuovext.pwsp.net

Kudos and thanks to Richard "Ricardo" Szlachta for his advice on refining the aesthetics of this theme.

This is my first Superkaramba theme and a work in progress. I would love to hear comments, opinions and suggestions in order to improve this theme.

bandwidth monitor is a small application which polls /proc/net/dev for the byte counts for a given network device , and calculates the RX and TX bandwidths. Originally a shell script, then a Perl script, now rewritten in C so that it can easily be used on embedded devices like the Linksys WRT54G as well as.

This program started as a shell script that I ran on my home-brew firewall wireless router (Linux, of course, on a 486/66) to keep track of my incoming and outgoing bandwidth. This let me know that I was getting the bandwidth that I paid for, and it also helped me keep an eye on the throttling of bulk traffic so that I didnt choke out my interactive sessions. Of course, that was before I had QOS.

The program is probably tied to Linux, since it grabs the byte counts for the requested interface right from /proc/net/dev. It could pretty easily be modified to grab the same information from the output of /sbin/ifconfig, but that would waste resources to spawn a new process to parse the /proc/net/dev file and regurgitate it to us. Also, I havent bothered to look at how uniform the output of the byte counts from /sbin/ifconfig is on other operating systems.

As a side note, the C version also uses nanosleep() and gettimeofday() to get more accurate polling intervals and track the overall time (since sleep(), usleep(), nanosleep(), et. al. only guaruntee to wait at least as long as you request, but do not guaruntee that it wont be possibly much longer...) So, if you were interested in porting it, youd have to make sure that nanosleep() and gettimeofday() were also available, or lose the resolution of the time used in bandwidth calculations.

Orange Monitor is a system monitoring theme for SuperKaramba.
Main features:
- CPU Load and Temperature (mbmon)
- Used RAM
- Used Space on hda and hda2 (customizable)
- Bandwidth Spent (bars are customizable , Incoming gets full @ 1GB and Outgoing @ 256MB by default)
- XMMS Controls (xmmsctrl)
Inspired on:
- Yaxay Skin for Winamp3
- Pod Icons for LiquidWeather karamba
- SystemTux Karamba

Simple Monitor is a SuperKaramba theme inspired by the simple but effective "Very Simple Monitors" theme by the user humanthing. Some values are not displayed properly though in Very Simple Monitors (network values and IP). This could be because of different setups. My computer is pretty standard so my theme should function properly on most pcs. http://www.kde-look.org/content/show.php?content=48973
I like a tight and clean desktop, so I simplified the idea even more. This theme is showing all basic information, and nothing more.
Main features:
- Processors type
- Processor speed
- Processor load (number and graph, for one proc)
- Processor Temperature
- Amount of ram used / amount of ram
- amount of swap used / amount of swap
- amound of HDD space used / amount of HDD space total (for "/root" and "/home")
- HDD temperatue (for "/hda", I could add another drive if requested)
- Computer name
- Computer ip
- Network load (up- and download, values and graph)
- Amount of transfered data thrue internet (up- and download) since last boot
Enhancements:
- Made the three blocks clickable.
- The CPU block opens Processor information
- The Memory block opens KsysGuard (youll need to have it installed to be able open it, obviously. Its in Kubuntu by default)
- the Network block opens your computers ip settings window
- Added a line for your computers uptime
- Changed font colors to very dark gray and very light gray, instead of black and white, to make it look softer.

Firewall Monitor allows you to monitor ipchains/iptables output in realtime. It supports both logging to a file/stdout and/or to tcpdump format capture logs. It also supports security features such as running non-root, and chrooting itself.
Fwmon can easily be integrated into an existing ipchains ruleset. As an example, fwmon can be easily integrated into the excellently commented TrinityOS ruleset available from http://www.ecst.csuchico.edu/~dranch/LINUX. The enhanced logging may be selectively added to specific existing rules by adding a new user-defined rule to the default ACCEPT, REJECT and DENY rules..This program has been known in the past as "Firestorm Firewall Monitor", however it shares nothing with firestorm.
If you wish to retain current ipchains logging features which RedHat and TurboLinux among other distributions make to /var/log/messages and add the additional features of fwmon, keep the -l option (or the $LOGGING equivalent used in TrinityOS) for those rules of interest. Fwmon data will be placed in a separate file (user-configurable) via a new target of those rules for which the capability is desired. Note that this new rule will not contain the -l (or $LOGGING) flag so packets trapped by a primary rule are not logged twice by ipchains. Additionally, by retaining the ipchains logging in primary rules, the rule number that caused the logging is contained in the ipchains log entries, and not the rule number of the new chain.
As a guide for adding this new chain, the TrinityOS rule set begins with setting of various parameters used with firewalls (flag settinga in the /proc directory, loading of modules, etc) then rules are grouped in INPUT, OUTPUT and FORWARD sections. Since this new rule will be a target of other rules, it must be placed BEFORE the first rule which references it to avoid errors the first time the ruleset is loaded. We suggest that a new
section defining the rule be placed just before the INPUT rules section and consist of:
Enhancements:
- Fixed logrotate problems with libpcap files. There is still a race condition but under normal circumstances you shouldnt encounter it, Ill think about fixing it all the same.

Virtual server monitor (vsmon) is a monitoring tool for Linux-VServer that gives a system administrator a global view of all vservers running on his park.
For now, it does not offer control over the vservers life cycle (e.g. provisioning, start, stop, and restart operations). To use vsmon, you must deploy one backend on each vserver host and one frontend, preferably in its own vserver.
Enhancements:
- The frontend was reworked to display a summary of all hosts.
- An owner can be assigned to each vserver.
- The backend can be used on hosts without Linux-VServers, and it no longer obtains IP addresses.
- The libdnet dependency was removed.
- The parsing of /proc/"pid"/stat now works for kernel 2.6.18.
- A Nagios plugin was added, which enables the use of the vsmon backend to monitor a host disk, memory, and swap.
- The plugin monitors all mount points according to an "intelligent" algorithm, which determines warning and critical thresolds as a function of the total size of the partition.
