Free 68000 software for linux

Linux is a clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.
It has all the features you would expect in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking.
Linux was first developed for 32-bit x86-based PCs (386 or higher). These days it also runs on (at least) the Compaq Alpha AXP, Sun SPARC and UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH, IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64 and CRIS architectures.
Linux is easily portable to most general-purpose 32- or 64-bit architectures as long as they have a paged memory management unit (PMMU) and a port of the GNU C compiler (gcc).
Linux has also been ported to a number of architectures without a PMMU, although functionality is then obviously somewhat limited. See the uClinux project for more info.
Enhancements:
- Add flags to frequency -> auto/fixed
- Document (struct iw_quality *)->updated, add new flags (INVALID)
- Wireless Event capability in struct iw_range
- Add support for relative TxPower (yick !)
- Change the way we get to spy_data method for added safety and hostap
- Remove spy #ifdef, they are always on -> cleaner code
- Allow any size GET request if user specifies length > max
- Start migrating get_wireless_stats to struct iw_handler_def
- Based on patch from Pavel Roskin :
- Fix kernel data leak to user space in private handler handling

Hatari is project an Atari ST and STE emulator for Linux, BSD, BeOS, Mac OS X and other systems that are supported by the SDL library. The Atari ST was a 16/32 bit computer system which was first released by Atari in 1985.
Using the Motorola 68000 CPU, it was a very popular computer having quite a lot of CPU power at that time. Unlike many other Atari ST emulators which try to give you a good environment for running GEM applications, Hatari tries to emulate the hardware of a ST as close as possible so that it is able to run most of the old ST games and demos.
Hatari is open source software and is distributed under the terms of the GNU General Public License (GPL).
Enhancements:
- This release brings you basic Atari TT and Falcon emulation! Please note that both new emulation modes are still highly experiemental, some few games and demos work, but most still have more or less big problems.
- Basic emulation of Falcon video shifter (Videl), NVRAM and DMA sound is in place. The biggest drawback: There is no working Falcon DSP emulation yet.
- Screen/Shifter emulation timings have slightly been changed. Some things now work better, some others work worse...
- Some patches for compiling on RiscOS and AmigaOS have been included.
- Compiling Hatari for Windows now works better.
- Added Hatari icon (hatari-icon.bmp).
- Fixed "movec" bug in 68020 CPU mode.
- Keyboard shortcuts for loading & saving memory snapshots (AltGr+k & AltGr+l).
- The built-in debugger has been slightly improved to be more user-friendly.
- Added "hmsa" tool a little program for converting .MSA files to .ST and vice versa.

Tools like ssh and lsh are great for allowing secure remote access to your system. They offer essentially full, flexible remote control of a machine, in an ecrypted and authenticated manner. But they are complex pieces of software; theres no way to do what they do without being complex. And with complexity comes bugs. Tools like ssh and lsh, and VPNs like CIPE, PPTP, and more have all had serious flaws that would allow an attacker to get full control over your system.
If you leave such programs running all the time, you take the risk that someone is going to use an exploit on you before you have a chance to apply a patch. For some purposes, this is an acceptable - even necessary - tradeoff, but it would be nice to enable them only when actually needed, to minimize the risk. And for other purposes, ssh et. al. are overkill. Perhaps you only really need to remotely initiate a limited set of operations. In this case, you dont need a shell prompt, just a way to securely kick off scripts from elsewhere.
Enter Ostiary. It is designed to allow you to run a fixed set of commands remotely, without giving everyone else access to the same commands. Ostiary is designed to do exactly and only what is necessary for this, and no more. The only argument given to the command is the IP address of the client, and only if the authentication is successful.
Main features:
- "First, do no harm." It should not be possible to use the Ostiary system itself to damage the host its running on. In particular, its willing to accept false negatives (denying access to legitimate users) in order to prevent false positives (allowing access to invalid users).
- Insofar as possible, eliminate any possibility of bugs causing undesired operations. Buffer overflows, timing attacks, etc. should be impossible for an external attacker to execute. Theres no point in installing security software if it makes you less secure.
- Be extremely modest in memory and CPU requirements. I want to be able to fire off commands on my webserver (running on a Mac SE/30, a 16MHz 68030 machine) from my Palm Pilot (a 16MHz 68000 machine). Things like ssh already take 30 seconds or more to start up - I cant afford anything too fancy.
- Keep things simple. Im no crypto expert; I know Im not capable of coming up with an ssh replacement. So I need to keep things so utterly simple that I can be sure Im not missing anything important.
Enhancements:
- Several non-security-related bugfixes, including some clarified log messages and an update to the TCP-wrappers autoconf macros.
- Debian packages have been added.
