Free endian software for linux

Endian Firewall is a "turn-key" linux security distribution based on IPCop that turns every system into a full featured security appliance. Endian Firewall has been designed with "usability in mind" and is very easy to install, use and mange, without loosing its flexibility.
The features include a stateful packet inspection firewall, application-level proxies for variuos protocols (HTTP, POP3, SMTP) with antivirus support, virus and spamfiltering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN). The main advantage of Endian Firewall is that it is a pure "Open Source" solution that is commercially supported by Endian.

The PXE daemon allows network managers to boot PXE-enabled machines over the network. Basically it envolves BOOTP, TFTP (so far so good) and a PXE daemon. This is where all the trouble starts. There is only one implementation arround, and if doesnt work on anything other than little endian machines.
I originally tried to correct some of the major problems in this code. However firstly, I could not find anyone with at Red Hat or Intel to deal with and secondly, Intel seem very unintrested in porting the code the big endian machines. The source is also very messy and it would have taken longer to correct the original code, than to re-write the whole daemon. If you dont believe me on this point, just have a look at it, IMHO any daemon that responds to keyboard input is a bad thing (it thinks it had packets coming from the keyboard even when in daemon mode)
You are lucky then, but a lot of places have already got a bootserver, and most likely it will be a UNIX based machine that is not x86. So, why put in another machine when there is already one there?
If you know enough about PC, you will know there are several operating modes. The mode the PC boots in is only able to access the low 640KB of memory. By using the PXELINUX bootstrap code it is possible to boot using the full amount to memory in the system. The means you can do some nice things including boot a Linux kernel + Ramdisk over the network, as you would for a Sun. Please note that the Intel bootstraping code is very limited in this sense.
I dont recommend it anymore, I just havent had time to do a lot of updates, PXELINUX is far far better (see link below). However Intels PXE daemon is naff (IMHO)
Enhancements:
- Increase the interface buffer to hold more than three interfaces
- Fixed a segfault in when multicast was disabled
- Fixed null pointer dereference when looking at interfaces with no IP address

ipidscan project consists in a portscanner using the ip.id method.
A portscanner using the ip.id method described by antirez on bugtraq on dec 15 1998. First public port scanner (that Im aware of) was published on bugtraq on dec 3 1999. This program was made public as a response to that on dec 4 1999.
The scanner does not directly contact the target host and is therefore practically untracable.
Main features:
- Default is to send null packets for echo:ing, some firewalls block them. Override with -F
- Lots of options. All nice.
- Use -e instead of -o 256 if silent host is a windows box
- Works on big and little endian boxen

Generator project is a Sega Genesis (MegaDrive) emulator.
Generator is a portable Sega Genesis (Mega Drive) emulator with gtk/SDL, SVGAlib and Tcl/Tk user interfaces.
It features its own unique portable 68000 core processor emulation enhanced by recompilation techniques.
Enhancements:
- [CORE] Support for Genecyst patch files / Game Genie
- [CORE] Support for AVI uncompressed and MJPEG output
- [68000] Re-added busy wait removal that got lost
- [SOUND] Added configurable single-pole low-pass filter
- [CORE] Added autoconf/automake version checks
- [VDP] Fix FIFO busy flag (Nicholas Van Veen)
- [SOUND] Various further endian improvements from Bastien Nocera
- and andi@fischlustig.de (Debian)
- [SOUND] Various BSD compatibility improvements from
- Alistair Crooks and Michael Core (NetBSD)
- [UI] SDL Joystick support from Matthew N. Dodd (FreeBSD)
- [68000] Do pre-decrement with two reads (Steve Snake)
- [68000] Make TAS not write (Steve Snake) fixes Gargoyles, Ex Mutant
- [68000] Re-write ABCD,etc based on info from Bart Trzynadlowski

Xyria:DNSd is an high performance DNS server that supports only the most important features and resource records while being extremely fast and secure.
Xyria:DNSd peoject also supports round-robin load balancing.
Main features:
- extemely fast implementation (main target)
- very secure
- ip-address based listen()ing
- supporting IPv6 addresses and resource records
- load ballancing via round robbin
- running under an low-privileged UID & GID
- running under little endian systems: (at least) Linux, Solaris, OpenBSD
- nice configuration syntax/easy to configure
- DNSd able to forward querys
- DNSd can run as caching only-server
Enhancements:
- The database was modified. Now DNSd uses a hashed array of pointers to binary trees including single linked lists for double valued hashes.
- It sorts the zones (by TTL) by itself (the admin doesnt has to care in which order he has to place the zones in the config file).
- Some code cleanup and a small bugfix are also included.

PearPC is an architecture-independent PowerPC platform emulator capable of running most PowerPC operating systems.

This release fixes an ugly partition mapping bug which prevented PearPC to boot OpenDarwin. But the fix might cause regressions: so if your image is no longer booting and you can compile pearpc yourself, please talk to the pearpc-devel mailing list.

Installation:

-Get the Mandrake Installations CDs from a near mirror.
-Read the getting started document first.
-Join the club.
-Make sure you have configured with a big harddisk (3 GiB should do) and a CDROM with the Mandrake 9.1 PPC CD1 inserted. Select a 15 bit video mode. (ppc_start_resolution to 1, 4 or 7)
-Boot and you should get the yaboot menu.
-Press enter and wait.
-At some point, a graphical installer will show up.
-I wont partition your disk for you so you have to do it on your own
create 2 partitions: Apple bootstrap and a Linux onecontinue install.
It will ask you to insert another CD. Click "Change CD" and choose a different .iso or simply insert a different CD. Continue.
-Something bad may happen in the end of the install. Nevermind.

While the CPU emulation may be slow (1/500th or 1/15th, see above), the speed of emulated hardware is hardly impacted by the emulation; the emulated hard-drive and CDROM e.g. are very fast, especially with OS that support bus-mastering (Linux, Darwin, Mac OS X do).

Because the author has only access to a little-endian machine, PearPC will most likely only run on little-endian architectures. This shouldnt be hard to fix and the author would fix this himself if he such hardware. (You can donate some big-endian hardware to get this fixed!)

Equally, PearPC will probably only run on 32-bit architectures. This shouldnt be hard to fix either. (You can donate...)
A lot of unimplementated features are fatal (i.e. will abort PearPC).
Timings are very still a little bit inaccurate. Dont rely on benchmarks made in the client.

PearPC lacks a save/restore machine-state feature.
No Altivec support yet but being worked on.
No LBA48 (but LBA). Currently no support for hard disks greater than 128 GiB. Disks > 4GiB are not tested very well.

mrouted project is a DVMRP multicast routing daemon.
mrouted is an implementation of the DVMRP multicast routing protocol. It turns a UNIX workstation into a DVMRP multicast router with tunnel support, in order to cross non-multicast-aware routers.
Enhancements:
- IGMP could report membership in local-only groups (i.e. 224.0.0.X)
- IGMP could get confused by hearing its own new membership reports, thus a router would never perform fast leave.
- IGMP could reset timers for the wrong interface.
- mrouted put a bogus value in the maximum timeout field of IGMPv2 query packets.
- Non-querier mrouters would respond to IGMP leave messages
- mrouted was not performing fast leave properly
- If the last member goes away on a transit network, the upstream router would stop forwarding even if there are downstream members.
- Kernel hash function improved
- Eliminated possibility of panic(): timeout in cache maintenance
- Reordered resource allocation when sending upcall to handle failure properly
- some endian-ness bugs squashed in mrouted, probably more to go.
- Multicast traceroute could send a reply on a disabled interface.
