Open SourceSaw the release distribution Scientific Linux 6.4, built on packet-based Red Hat Enterprise Linux 6.4 and supplemented with funds focused on the use of scientific institutions.

Distribution available for the i386 and x86_64, is available for download multiple assemblies: installation DVD (3.4 GB), a full set of two DVD (4.2 GB + 420 MB) and the reduced image for network installation (159 MB). Live-version of Scientific Linux 6.4 will be prepared later.

Differences of Scientific Linux 6.4 with version 6.3, not related to changes in borrowing from RHEL, include:

– Modified method of encapsulation for the kernel module to support the client OpenAFS, open source implementation of a distributed file system Andrew File System. The main difference is in the method of assembly: if you had one kernel module was going right for the nuclei of all issues of Scientific Linux 6.x, now for each issue formed a separate version of the module.

– Realized default package yum-conf-sl6x, which contains settings to update Yum-repository as new releases of Scientific Linux 6.x, which allows you to automatically switch to the latest version of Scientific Linux 6.x immediately after its publication, without additional manual manipulation to initiate update distribution;

– The package yum-conf-sl-other record added to support the repository ‘sl-addons’, which houses packages that claim to be included in future releases, the packets with an uncertain future, or which can not be added to the repository main;

– Because of the elimination of vulnerabilities in xorg-x11-server changed ABI. Since the change is due to security update package with a modified ABI will be presented for the previous editions of Scientific Linux 6.x;

– Dropped support for outdated Matahari API, used to govern the system.

Common differences Scientific Linux 6.x of RHEL 6.x:

– The window manager IceWM 1.2.37;

– OpenAFS – open source implementation of a distributed file system Andrew File System;

– Set developed in Project Fedora tools for creating Live-CDs and derivatives assemblies. To create your own Live-drive, you can use the package livecd-tools, to capture the image on the USB-drive to use liveusb-creator;

– Package yum-autoupdate to automate the daily updating of the system;

– Support for additional repository: adobe, atrpms, elrepo, epel and rpmforge;

– Added some scripts to change from the default settings: SL_desktop_tweaks (change of the menu GNOME and KDE), SL_enable_serialconsole (inclusion entry through the serial port), SL_no_colorls (off color output for the command ls), SL_password_for_singleuser (inclusion need to enter the root-password to log in single-user mode (single mode));

– Visualization package Graphviz;

– Library Numpy, for the organization of scientific computing;

– Driver iwlwifi firmware includes additional (firmware for wireless cards Intel series 5150, 3945, 4945, 5000, and the current version, 6000;

– XFS filesystem support for architecture x86_64. The installer can not be created until the XFS partition, but install Scientific Linux on XFS partition you created earlier, you can;

– FUSE-ins and fuse-smb fuse-sshfs, to mount SMB and SSH;

– It will be recalled that most of the previously available in Scientific Linux 5.x scientific applications are not included in the basic repository Scientific Linux 6.x, but can be found in the additional repositories, such as EPEL, elrepo.org and atrpms.net. In addition, longer supported repository contrib, which placed additional device drivers – analogues of contrib packages can also be found in external repositories and elrepo atrpms.

Previously present in SL5 packages that can be found in the external repository EPEL:

– Library cfitsio format support with the implementation of FITS (Flexible Image Transport System), which is used in astronomical research, for C and FORTRAN;

– Technology DKMS (Dynamic Kernel Module Support), to automatically rebuild the current kernel modules device drivers after updating the kernel. Introduction DKMS will automatically install the drivers that are needed for certain hardware components of the current system, but not in the standard Linux kernel. For developers, DKMS provides a means of creating drivers without regard to the features of the different versions of the Linux kernel.

– Console mail client Alpine;

– Additional Perl-modules: DBD-XBase, MailTools, Parse-RecDescent, SQL-Statement, TermReadKey, Text-CSV_XS, Text-Template, Tk.

Previously present in SL5 packages that can be found in the external repository atrpms:

– The math library FFTW (Fastest Fourier Transform);

– 915resolution utility to modify the video BIOS for graphics cards based on the GPU Intel 845G, 855G, 865G, 915G, 915GM, and 945G, which allows for the installation of additional screen resolutions;

– GNU R (language for statistical computing);

– Additional multimedia codecs (gstreamer-plugins-extras of SL4 and k3b-extras from the repository livna);

– Library matrix calculations SuiteSparse.

Previously present in SL5 packages that will have to download from the developer:

– Scientific library SciPy, which can be used for scientific, engineering and mathematical calculations, in and for charts and graphs based on a set of statistical data;

– Sun Java / JDK – in the now comes only OpenJDK;

– A set of learning applications for KDE – KDEEDU.
