  1. HEPIX • May 2004 Edinburgh • http://hepwww.rl.ac.uk/hepix/nesc/agenda.htm • Linux/Unix highlights

  2. SLAC OS Status • Linux • RedHat Enterprise 3 (RHEL3) rolling out to most servers and desktops • Begun weekly RedHat service meetings (by phone) • About 20 issues opened so far with them (missing function, driver issues) • Have yum-based service to pull updates to systems. • Working out how to update mobile/offsite systems (up2date?) • ALDI project to automate desktop upgrades

  3. DESY- Linux • DL5 (SuSE 8.2) rollout in progress (25% done) • support for base distribution ends April 2004 • 9.0 patches will help for another 6 months • successor - better: continuation - needed early next year • DL5 is most likely the last DESY Linux based on SuSE • if a common HEP distribution with long lifetime is available and affordable, that's what we'll use • started looking at Scientific Linux • thanks to Fermilab for providing this! • current version seems very compatible with DL5 (for users) • purchase of licenses is an option - if price/value ratio ok

  4. DESY- Linux/amd64 • aka ia32e aka x86_x64 • first test system is a success • IBM eServer 325, 2 x Opteron 246 (2.0 GHz), 4 GB RAM • SuSE 9.0 Professional/amd64 • performs superior to fastest Xeon Systems (3.2 GHz) • except FP • ROOT applications especially fast, benefit from 64bit mode • deployment of a small number of production systems soon • seamless integration is relatively easy • concern: cernlib dependency locks users into 32bit past

  5. DESY-Security • rules for individually maintained systems are in effect now • regular scans from outside our firewall • of all hosts with any port open through firewall • for open ports and known vulnerabilities • by commercial service provider • access to mail servers now by imaps only • got rid of clear text protocols pop and imap • automated deployment of patches • linux, old NT domain (netinstall), new XP domain (SUS) • policies still evolving

  6. DESY - Security continued • due to recent sasser threat, manually checked ALL notebooks brought on site for two days • only a few systems got infected • increased update frequency for virus signatures • update server: hourly, client: every three hours • a few users were tricked into installing Bagle.J • lesson: treat encrypted attachments like executables, and quarantine them • firewall now inhibits outgoing SMTP, except for approved mail servers • imagine all sites and providers did that
