Linux support in Zeuthen is based on Scientific Linux, an effort kindly made available by FNAL with contributions from other labs.
SL is in use at virtually all HEP sites and many other labs, universities, and enterprises.

Status of SL Releases
Scientific Linux 7
SL7 is expected to become available late in 2013.
Scientific Linux 6
SL6 is available and fully supported, and it's what we install on any new system except on special request. Users are welcome to have it installed on their desktop, and groups are welcome to have it installed on their WGSs. Migration of farms and WGS has started in autumn 2011. A significant number (~ 500) of fast cores in the farm is running under SL6 already, providing the better part of the computing power. All GPGPU systems run SL6.
SL6 should work on newly released hardware until the end of 2014. General support ends November 2020.
Scientific Linux 5
SL5 has been our workhorse since Summer 2007, and is now gradually being replaced by SL6.
New hardware may work with SL5, but at the time of this writing we just don't know. Supporting existing systems will be possible until April 2017.
Scientific Linux 4
SL4 was largely skipped, although a number of systems were used for providing services, as ATLAS WGS, and in the NAF. As of March 1st, 2012, SL4 is completely unsupported and all remaining systems were shut down.
Scientific Linux 3
SL3 was our workhorse from early 2005 to Summer 2007. It no longer works on any current hardware. There are no more SL3 desktops, no more servers, and only a very few special purpose systems used by a single project.
Full upstream support ended November 2007. On December 1st, it transisitioned to "Legacy support". See this copy of the announcement.
Within these limitations, existing SL3 systems were supported until October 2010, the end of life date of RHEL3.
Local Repositories and Mirrors
We mirror the current SL5 and SL6 releases: Local_Linux_Repositories
Network installations (http) are also possible from these repositories, using the small boot.iso CD images found in the images/ subdirectory of the distribution.
Full iso images are usually available in /project/linux/iso.
