The Gentoo Release Engineering team proudly announces the release of Gentoo Linux 2006.0. Gentoo Linux 2006.0, the first release in the 2006 series, represents improvements across many architectures since the 2005.1 release.

Major highlights in the release include KDE 3.4.3, GNOME 2.12.2, XFCE 4.2.2, GCC 3.4.4 and a 2.6.15 kernel. This is also the first release with the Gentoo Linux Installer officially debuting on the x86 LiveCD, which will fully replace the Universal and PackageCD set. The LiveCD also features a fully-fledged Gnome environment. Later releases will include KDE support as well as a new LiveDVD.

The PPC64 team has made significant improvements in its release media. IBMs hardware donation to the team greatly helped this and ensured a smooth release. The CDs feature 64-bit kernels and 32-bit userlands rather than the previous pure 64-bit environment. Optimized stages are available for the G5 and POWER5 processors, making Gentoo the first distribution optimized for POWER5 out-of-the-box. The new release includes an experimental CD with full framebuffer support for dual-core G5 machines along with thermal management features. This makes Gentoo the first to market with release media with this level of support.

PPC and PPC64 profiles received further reorganization. They now match those of other 32/64-bit architectures such as SPARC and MIPS, unifying the look of the tree and allowing easier creation of specific profiles (for example, for server use) in the future. The PPC discs improve support for newer Apple laptops such as the last series of PowerBooks, which 2005.1 did not support, and feature improved OldWorld support with BootX on the universal CDs. The PPC team now produces the PackageCDs in a G4 and a ppc-generic configuration, especially useful for older and slower machines.

The Hardened team is pleased to release both 2.4 and 2.6 kernel targeted stages for the x86 platform. The previously experimental non-multilib AMD64 stages are now part of the 2006.0 release, while Hardened Gentoo with multilib on AMD64 has become possible and the team is releasing experimental stages.

The 2006.0 AMD64 release moves EM64T support out of the experimental realm. The InstallCDs feature support for NVIDIA SATA and for SysKonnect Yukon2 network cards as well as the inclusion of 32-bit Java Support. An experimental LiveCD is also available, featuring the Gentoo Linux Installer.

The Alpha team now provides split NPTL profiles as part of the 2006.0 release -- NPTL must use a 2.6 kernel, and those who require a 2.4 kernel or do not wish to enable NPTL can use the no-nptl subprofile instead to not take advantage of the new threading model. Stage tarballs are now provided for both variants, and the InstallCD provides both 2.4 and 2.6 kernels.

SPARC has moved to GCC 3.4.5 from the older 3.3 series and also to glibc 2.3.5 from 2.3.3 -- the profile features a 2.6 kernel and headers. However, this feature remains experimental and the SPARC team built the release media with the 2.4 subprofile. Testing from SGI Quality Assurance allowed the IA64 team to update its InstallCD to boot on SGI Prism machines.

Gentoo Linux is a community-driven project committed to producing a high-quality open source distribution; more information regarding this release, such as detailed release notes will be available on the Gentoo Release Engineering teams project page.

Gentoo Linux uses an enhanced BSD ports-style package system.

Bluewhite64 Linux is an unofficial port of Slackware Linux to the AMD64 architecture. This means that it runs on AMD64 based servers and computers.
Bluewhite64 Linuxs goal of this port is to mimic the user experience of the Intel x86 distribution at its best. I will try to include the same software, configuration scripts and so on. If you notice any differences between Bluewhite64 and the original Slackware, dont hesitate to email me.
Enhancements:
- This version includes the Linux 2.6.21.5 kernel with the IA32-emulation enabled, the testing Linux 2.6.22 kernel in the testing/ directory with support for IDE, SATA, SCSI, and RAID controllers, Ext2, Ext3, ReiserFS, XFS, and IBMs SGI filesystems, SCSI and ATA RAID volume, software RAID, LVM2, KVM (Kernel-based Virtual Machine), and encrypted file systems. It also includes the GCC 4.1.2 compiler and Glibc 2.5 with NPTL, the latest KDE 3.5.7 and XFce 4.4.1, the Mozilla Firefox browser and Mozilla Thunderbird 2.0.0.4, SeaMonkey 1.1.2, Apache 2.2.4, PHP 5.2.3, and MySQL 5.0.37.

qgreylistrbl is an add-on for qmail.

Now there are a lot of methods against spam, I have combined two of them: greylisting only for dialin nodes and nodes listed on a RBL. NDNs with more than one recipient will be rejected with permanent error messages and without a greylist entry. A test for EHLO/HELO spoofing was added: if a string is obviously spoofed, the connection will be rejected with a permanent error message, without a greylist entry, and advice to RFC2821. You can define a maximum number of recipients per email.

Greylisting returns a temporary SMTP error at the first delivery attempt. Most spam is sent from bulk mailers that dont retry, so these attempts are blocked. Real mail servers will retry later after a temporary error, allowing the message to go through.

Of course cannot all mail be delayed half an hour or longer to our customers. Thats why I have decided to modify the program qgreylist from Jon Atkins. I have added a RBL request to accept emails from not RBL listed nodes and to delay only dialin lines and RBL listed nodes. The script tests the PTR record of each connecting host for a regular expression to detect dialin nodes.

qgreylist from Jon Atkins puts all files in one base dir. qgreylistrbl creates here a directory structure because of performance reasons. The cleanup is now done by a separate cronjob script and not by qgreylistrbl itself, because when there were some ten thousand files inside the mail server nearly stands still.

Most bulk mailers and zombies,too, do not have queue management. They blast that much emails out into the net, they would be swamped with it. An Example: We use a UW-160 Raid 10 for the queue, but the usual zombie out there has only one IDE disc. Beside even a layman would ask why his hard drive was running all the time.

Effect

80% less spam. Yes, truly. No false positives, NO email gets lost.

Usage

qgreylistrbl is a replacement for rblsmtpd by D.J. Bernstein. Simply put qgreylistrbl instead of rblsmtpd in the command line for starting qmail-smtpd.

Performance

qgreylistrbl is a Perl script. Expect some CPU usage. If you run a QMAILQUEUE-patched version of qmail-smtpd and spamassassin, the load will decrease extensive, because most connection attempts do not cause a mail delivery. With perl > 5.6.1 you can precompile the source code with perlcc.

Installation:

Just copy the perl script wherever you want and edit the start script for qmail-smtpd. qgreylistrbl is a simple replacement for rblsmtpd from D.J. Bernstein and can be used the same way.

Create the greylist IP folder:

# mkdir /var/qmail/qgreylistrbl
# chown qmaild /var/qmail/qgreylistrbl

Adjust User

If you need to install the perl module Mail:RBL, just do the following:
From the root prompt on your server, invoke the CPAN shell:

# perl -MCPAN -e shell

Once the Perl interpreter has loaded (and been configured), you can install modules by issuing the command install MODULENAME.

The first thing you should do is upgrade your CPAN:

cpan> install Bundle::CPAN

Once its done (it will take a while, just enter all questions), type:

cpan> reload cpan

Now, enter the following command to retrieve all of the required modules:

cpan> install Mail::RBL

Then you can be shure everything is installed to correct locations.

Configuration:

At the beginnung of the script you have to adjust a few variables. See script for more details. Important are hostname, working directory, some paths and RBL services. You have to add a crontab entry as follows:

*/20 * * * * vpopmail /var/qmail/bin/qgreylist_cleanup.pl

Adjust user, path and time before.
Dont forget so set up logging facility in /etc/syslog.conf

mkinitramfs is intended to create the ultimate initramfs image.

mkinitramfs is designed to boot from any media (SATA, PATA, SCSI, USB, CD-ROM, etc.) without any changes being made to your disk.

However, it is very simple (about 400 lines of code).

Parchive project is a tool that helps data recovery of multi-part archives on Usenet.

The original idea behind this project was to provide a tool to apply the data-recovery capability concepts of RAID-like systems to the posting and recovery of multi-part archives on Usenet. We accomplished that goal. Our new goal with version 2.0 of the specification is to improve.

It extends the idea of version 1.0 and takes the recovery process beyond the file-level barrier. This allows for more effective protection with less recovery data, and removes some previous limitations on the number of recoverable parts. See Par1 compared to Par2 for a more detailed view of the differences.

Because this new approach doesnt benefit from like sized files, it drastically extends the potiental applications of PAR. Files such as video, music, and other data can remain in a usable format and still have recovery data associated with them.

The technology is based on a Reed-Solomon Code implementation that allows for recovery of any X real data-blocks for X parity data-blocks present. (Data-blocks referring to files OR much smaller virtual slices of files).

The key to this mission is a clean file format specification which provides all the necessary capabilities for programs to easily verify and regenerate single missing parts out of a set of data-blocks.

Trinity Rescue Kit or TRK is a 100% free CD bootable Linux distribution aimed specifically at offline operations for Windows and Linux systems such as rescue, repair, password resets and cloning, with the ability to update itself.
It has custom tools to easily recover data such as deleted files, clone Windows installations over the network, perform antivirus sweeps with 2 different antivirus products, reset windows passwords, read AND write on NTFS partitions, edit
partition layout and much much more.
Trinity Rescue Kit 3.1 is the evolved version of 3.0 and a complete rewrite of version 1.1 and the unfinished 2.0. It s mostly based on Mandrake 10.2 (Mandriva 2005) binaries and heavily adapted startup scripts.
What s new since 3.0?
- self update capability: TRK now has a script that will download/search all non-GPL
licensed software, like the Microsoft ntfs
drivers or F-prot. It will also update antivirus definitions for F-prot and Clamav.
Afterwards, it will recreate itself as a new iso
file which you can burn again to CD
- new version of captive-ntfs, using the latest XP SP2 drivers and LUFS
- clamav 0.88-1
- mkisofs, cdrecord, pico, cfdisk
- eject CD (was bug in build 204) and powerdown on halt
What s new since 1.1 (and 2.0):
- more hardware support:
kernel 2.6.14.3 with most default options left on, so all important hardware like
disc controllers and network cards are supported, even SATA disks, USB storage and gigabit ethernet. Also patched with lufs (for ntfs support) and bootsplash (background graphics)
- better network capability: besides all common network client tools, you can also run a secure shell server for remote access or TRK to TRK file copies
- run completely from memory: provided you have at least 192Mb of ram, you can run TRK from memory and eject the CD once it has booted, giving you the ability to mount other CDs
- vesa framebuffer support: TRK now has limited graphical support thanks to kernel
builtin framebuffer support.
- qtparted: the famous PQMagic clone. Partition editing never been this easy thanks to the graphical interface this tool uses (via framebuffer)
- configure your LAN to be "TRK 3 compliant": you can change the way a TRK behaves by adding an otherwise unused parameter to your DHCP server to point to a webserver where you keep specific configuration data for your TRK such as proxy settings or complete scripts with which you can do anything you want
- run scripts from a local computer by searching for /.trk/trklocal.conf
- full NTFS write support thanks to the captive ntfs project by Jan Kratochvil.
- more NTFS write support with the NTFS Fuse driver.
- Secure Shell server: let a user boot from TRK, enter a new password for root and
connect to TRK remotely
Featuring home brewed scripts, new and improved:
- updatetrk (since 3.1): updates TRK with ntfs drivers, F-prot + definitions and
Clamav definitions. When the script is run without arguments, it looks for a Windows pagefile.sys, creates a loopback filesystem on it and creates TRK from there. Afterwards it copies the new isofile to C: emp, from where you can burn it to CD again
- clonexp: script that uses ntfsclone to perform copies of ntfs filesystems between
two computers each running their copy of Trinity Rescue Kit 3.1. One PC copies his Windows installation over the network to another PC running a TRK 3.1 with a secure shell server enabled. An easy way to clone Windows installations or recover as much as you can from a dying disk. Run it either interactively or from a single commandline
- winpass: does the same thing as in TRK 1.1, searches for all local Windows
installations, runs chntpw on your SAM file and resets the password. It now also handles Windows on FAT32 correctly and uses the safe ntfs driver from the Linux kernel, so it works even without captive support
- regedit: is actually the same as winpass, but starts chntpw in interactive mode and allows you to edit a Windows registry
- virusscan: completely rewritten,this script now has two different engines: the default is to run with the GNU Clamav antivirus which is free for everyone. This is a very good scanner, but the drawback is that it can only detect virus infected files, not clean them. So the only option is to delete them, where most of the time the file is the complete virus. But just to be sure we don t delete anything valuable, a quarantined backup is being made first. The other part of the script uses the free-for-home-users F-prot. F-prot itself is not included in TRK but it gets downloaded from their site. F-prot DOES have the ability to disinfect files if necessary.
- ntfsundeleteall: also completely rewritten, ntfsundeleteall, a wrapper for
ntfsundelete now recovers deleted files from an NTFS volume but it gives you the ability to add a recoverability percentage to the commandline. Since it only recovers files and not directories, sometimes you would have double filenames. This has been countered by adding the inode of the file at the beginning of the filename, so recoverability is 100% within the possibilities of ntfsundelete
More utils:
- links: simple webbrowser which runs in framebuffer graphical mode. Handy to go and read some reference docs on the Internet
- ftp and lftp
- ssh and scp
- ms-sys: This program is used to create Microsoft compatible boot records. It is able to do the same as Microsoft "fdisk /mbr" to a hard disk. It is also able to do the same as Microsoft "sys d:" to a floppy or FAT partition except that it does not copy any system files, only the boot record is written.
- Reiserfs tools
- ext2/ext3 tools
- ntfsprogs
- dosfs tools
- tcpdump, nmap and netcat
- mdadm for offline raid configuration
- burn, a utility that stresses your CPU
- samba client: mount windows shares over the network
- shred: erase a harddisk until its unrecoverable even by magnetic resonance recovery
- fatback: undelete files from fat filesystems
- TestDisk: Tool to check and undelete partition, works with most common partitions
- PhotoRec: File and pictures recovery. PhotoRec has been created to recover pictures from digital camera memory and it has been extended to recover lost files from harddisk (List of known files). PhotoRec is safe to use, it will never attempt to write to the drive or memory support you are about to recover from. Recovered files are instead written in the directory from where you are running the PhotoRec program.
- pico text editor
- mkisofs and cdrecord
- perl 5
Enhancements:
- Very extensive and complete documentation.
- 2 more virus scan engines: Grisoft AVG and BitDefender.
- ntfs-3g has full and fast read/write support for NTFS drives.
- Bootable from a USB stick and over PXE.
- An integrated Samba file server.
- LVM support.
- Kernel 2.6.19.2 and hwdata 0.191-1.
- Menu-based graphical startup.
- Tools to migrate TRK from CD to USB and back to an ISO file if desired.
- Bridging capabilities.
- Full proxy server support: a script called "setproxy" can prompt you for your networks proxy parameters, allowing you to access the internet and update your TRK.
