Free swaps software for linux

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.

Laptop-Hotswap kernel module enables hot-swapping for disk drives with full DMA support under Linux. It requires kernel 2.6.15+ and ACPI.
I think it ought to work on just about any laptop, although Im not as familiar with ACPI as Id like to be. It works fine on my T22. There could be issues with laptops with two expansion bays -- I shut down the entire ide1 interface and fire it back up, and I do all my watching on the ACPI device for the IDE1/Master. So if you had a slave device, and you ejected the master, your slave will go bye-bye. Thinking about ways around that, but they dont export too much of the ide driver. I think itd be easy to handle, you just have to make sure youre not using either master or slave whenever you eject one of them.
At least on my laptop, dont go pulling things while your laptop is sleeping. Do it when its awake.
The floppy support should work, but my floppy drive isnt with me right now.
Theres one parameter -- auto_eject. If you set it to 1, the driver will automatically shut down and unregister the IDE interface upon getting a request for ejection (On my T22, I pull a little switch and a lever pops out -- the drive is still connected at that point, but it shows as a request for ejection). If your laptop doesnt have a mechanism for that:
echo -n "MSTR eject" > /proc/acpi/lths
Will shut down and software-eject the drive, and you can safely pull it and insert another.
See the scripts in config/ -- theyre made to work with acpid to handle the ejection and umounting and insertion. The mount/umount stuff only matters for a drive caddy, I suppose.
It shouldnt matter what you have in your laptop at boot. This module also fixes that annoying thing on my T22 where if I dont have a ultrabay battery in at boot, I cant ever see its status.
Enhancements:
- Support for the Fujitsu S7020 (and possibly other laptops using a PATA bay with an SATA main disk).

Sepp is a version of the classic sliding puzzle game in which the properly ordered tiles form a picture.
Sepp, the Sliding Evil-Piece Puzzle, implements a computer version of the classic moving puzzle game, which has 15 sliding tiles in a 4-by-4 matrix and is also known as the 15 puzzle, in which the properly ordered tiles would form a picture.
Variants like Loyds would be unsuitable for this version of the game because a picture in which two contiguous tiles were swapped (and which, therefore, could not be recomposed) might annoy users and likely be perceived as a bug in the program; therefore, Sepp does not perform arbitrary tile swapping when scrambling the tiles, and the original image can always be obtained given enough tile pushes.
On the other hand, Sepp implements its own innovative kind of player aggravation: based on a user-configurable degree of evil, ranging from Not at all evil to beyond Very Evil, Sepp decides, during each animation frame, whether it will disturb a tile while the game is in progress. For better or worse, this feature, which can be disabled by setting the evilness to Not at all evil, sets Sepp apart from other, similar games.
Main features:
- Sepp allows the player to select the tile that will be used as the empty slot by simply clicking on it before scrambling the tiles; this setting is remembered by Sepp for as long as the players session stays in the puzzle in which the tile was chosen, and is dismissed when the user chooses a different picture or different grid geometry.
- Sepp keeps track of time spent by the player in solving the puzzle, but displays it only if and when the puzzle is solved; in this regard, Sepp implements the same behavior as the casual game Frozen Bubble and avoids distracting and terrorizing the user during gameplay.
- The terror that Sepp does cause its players comes in four levels, and can be set using an options menu that is available with a single click immediately after startup; in consideration of the elderly, the children, and small household appliances, "evilness" is disabled by default.
- The Sepp player can enjoy endless hours the aggravation using the input device of his choice, whether it be the keyboard or the mouse: except for empty slot selection, all operations can be performed with either; additionally, Sepp does not require dragging of the tiles but instead supports single-click action.

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.

asMon is a system monitor for Linux systems running afterstep, but should work on other window managers, too. I got fed up with most other wharf system monitors that didnt show the correct memory usage, and took up too much CPU. asmon also shows the exact amount of memory used and load avg by the numbers. The CPU bar is fairly standard, next to it is the current load average.
The second bar is memory usage, taken as a whole, it represent the amount of memory used. The area before the first tick represents shared memory, the area between the two ticks is buffered memory, the area from the second tick to the end of the bar represents cached memory.
The number to the right represents the number of megs currently being used. The third bar represents the amount of swap file used, and the exact number of megs the swap is using. The bottom right is are page/swap LEDs taken from wmsysmon. The right is uptime. The original program is based off of Timecops wmcpu.
Enhancements:
- After many years, another release has arrived. This time with Kernel 2.6 support and a bunch of bug fixes.

KuSys-Info is a Ku(buntu) Sys(tem)-Info.
KuSys-Info karamba applet is based on transwhite. I adapted it a bit and modified it so that it fits to my system and themes.
Detection of OS is not automatically right now, so you probably have to adapt the script.
To change to the right network interface change all ra0 entries to your interface.
Displays:
- CPU fan, usage and type
- System ID, KDE version and user
- Uptime, kernel version
- RAM and SWAP Usage
- network traffic
- hard disk usage
