Free swap meets software for linux

swapd is a dynamic swap creation deamon, it monitors the system memory and detect when swap creation will be required. the swap size is determined automatically with respect of sysadmin limits.
Installation:
- Make sure you are logged in as root.
- Run make install.
- Take a look at /usr/local/etc/swapd.conf and change what is necessary.
- Create the swap directory you chose in swapd.conf (it should be accessible only by root).
- Add the following line to /etc/rc.d/rc.local:
/usr/local/sbin/swapd
- If you recompiled the kernel, now would be the time to reboot. If you havent, just rehash and run swapd as root.

The cryptoswap package supports building an encrypted swap partition when a system boots. This must be necessary on systems that use encrypted filesystems because plaintext secrets may be written to disk when memory is swapped to disk.
Cryptoswap.sh should be installed in /etc/init.d. During system boot, cryptoswap.sh should execute right before checkroot.sh. When shutting down, cryptoswap should execute after sysklogd.
This package also includes an initialization script for building loopback encrypted /tmp. This may be necessary if a system contains encrypted filesystems but / is not encrypted. A link from directories like /var/tmp to /tmp may be appropriate. There are a few other alternatives for systems such as these:
1. Tmpfs is a Linux kernel feature that allows /tmp to exist in memory. This is a good solution for systems with a lot of memory and/or (encrypted) swap.
2. If you have a system that uses encrypted home directories, per-user temporary directories inside $HOME could be used. This would ensure that users data is protected but would require that all applications use $HOME/tmp instead of /tmp.
Finally, the project may be used to create an encrypted root filesystem. Doing so requires two special partitions. First, create a small partition to hold your kernel and initrd image, /dev/hdaX. Second create a large partition to contain the root of your filesystem, /dev/hdaY.
Next configure and install an initrd-based boot system:
1. Ensure romfs is compiled in your kernel (not a module).
2. Create a kernel-supported filesystem on /dev/hdaX and copy your kernel to /vmlinux.
3. Download busybox and extract it as initrd/busybox.
4. Update initrd/src/etc/modules.initrd to include any modules needed to boot.
5. Build cryptoswaps initrd image (cd initrd && make initrd) and copy it to the filesystem on /dev/hdaX at /initrd.img.gz.
6. Make sure you use literal = "root=/dev/ram0 init=/linuxrc rw" or LILO equivalent.
Finally, create a proper encrypted filesystem on /dev/hdaY:
1. Randomize the partition: dd if=/dev/urandom of=/dev/hdaY.
2. Set up a loopback device: openssl enc -d -aes-256-ecb -in initrd/src/etc/efsk | losetup -p0 -e aes /dev/loop0 /dev/hdaY.
3. Create the root filesystem: mkfs.ext2 /dev/loop0.
4. Mount your new root filesystem: mount /dev/loop0 .
5. Populate your new root filesystem.
Enhancements:
- Added initrd build environment.
- Documentation update.

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.

WMMemFree shows system memory usage. It runs as a dockapp for WindowMaker or some other window manager which supports dockapps.
On the top side you have your physical memory usage and on the bottom theres
your swap space usage. The following options can be passed to WMMemFree on the command line:
-h, --help - display basic usage info
-v, --version - display version
-display - specify the X11 display to connect to
-b, --buffers - consider buffer memory
-nb, --no-buffers - ignore buffer memory
-c, --cache - consider cache memory
-nc, --no-cache - ignore cache memory
-w, --window - run in a window
-nw, --no-window - dont run in a window
-s, --shape - use the XShape extension
-ns, --no-shape - dont use XShape extension
Enhancements:
- Now windowed mode will have no decorations, the window can be moved with the mouse.

OAMP stands for (O)penBSD + (A)pache + (M)ySQL + (P)ostgreSQL + PHP. The project is the OpenBSD cousin of LAMP, except that it also provides the SQlite database engine, Perl, Ruby, and Python.

In addition, OAMP provides phpMyAdmin and phpPgAdmin for easy administration of MySQL and PostgreSQL over the Web.

OpenBSD is widely regarded as the most secure operating system in existence and its features can be used to satisfy all aspects of information assurance (i.e. confidentiality, integrity, availability). For instance, as of version 4.0 OpenBSD encrypts the swap partition by default and puts the Apache server in a "jail" environment, so if it is compromised the damage will be contained. In addition, all applications that come with OpenBSD have undergone source code audit and have been hardened accordingly. OAMP also provides the SQLite database, Perl, Python and Ruby.

sarPplot project is a simple application which takes output of atsar application and put it into Gnuplot config files, kind of useful on server boxes for performance analyze, which is availabel on:
- cpu
- processload
- disk
- disk-partition
- memory&swap
- paging&swapping
- interrupts
- kernel-resources
- ttyactivity
- net-interf(general)
- net-interf(errors)
- ipv4(general)
- ipv4(errors)
- tcpv4(general)
- tcpv4(errors)
- udpv4
- icmpv4(general)
- icmpv4(pertype)
- nfs(general)
- nfs(errors)
- nfs(server)
- nfs-rpc(calls)
Enhancements:
- A grid feature was added along with httprequests and httpdpid targets.
- A bug in the interr function was fixed.

Atop project is an ASCII full-screen performance monitor, similar to the top command.
At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks and network layers, and it shows for every active process the CPU utilization in system and user mode, the virtual and resident memory growth, priority, username, state, and exit code.
The process level activity is also shown for processes which finished during the last interval, to get a complete overview about the consumers of things such as CPU time.
Atop only shows the active system-resources and processes, and only shows the deviations since the previous interval.
Enhancements:
- A new command, atopsar, has been added to generate detailed system activity reports (similar to the UNIX command sar) using the compressed logfiles as written by atop.
- These reports can also be generated for the current situation by specifying an interval for atopsar on the command line.

iSAK, Internet Secure Access Kit, is an integrated Open Source applications package that gives an efficient departmental access control of Internet services. Right now, many installations of iSAK have been made by Savoir-faire Linux.
Multiple versions of iSAK will be available shortly. Each version differs by its features and the way the Open Source applications are integrated together. Moreover, each installation of iSAK is different because it meets the enterprise requirements.
Enhancements:
- This release includes a new log processing engine for Squid.
- The engine is based on JasperReports to produce professional reports of your network Web activity.
- This version can categorize your Web traffic because of a complete integration of iSAKurlDB.
- Note that is it possible to use this log processing engine without using all iSAK features.
- You can plug it into your actual squid server.
