  1. HEPiX-HEPNT 2000Report Enrico M.V. Fasanelli & Gian Piero Siroli

  2. We Apologies to the Audience… • Written (you may read: “cutted-and-pasted”) in English directly from the HEPiX-HEPNT 2000 talks (without the permission of authors) • Long and annoying • But there is two full days ( two lunch, four coffee breaks, and two dinners) with 21 official talks • Incomplete Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  3. Outline of Workshop Summary • Approach to Windows 2000 • Windows 2000 deployment • Application deployment/support • Security / Authentication issues • Web services • Other utilities • Windows Terminal Server • Exchange • HEP applications (triggered by GPS) Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  4. Approach to Windows 2000 • The common approach: Form a committee… • New w2k domain for DESY. • integrated to the existing NT one (migration by evolution from NT to W2000). • CERN is following the MS recommendations for the NT4 to W2000 migration. • a lot of problems in migrating out of Novell NetWare • MacOS too is a problem (policy problems). • Production date of W2000/NICE2000 is delayed… • RAL (CLRC) has W2000 only on some laptops and servers and move cautiously towards Active Directory. • The existing NT4 domain is crucial to lab • They are now inside the clrc.ac.uk domain with Daresbury Lab Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  5. Approach to Windows 2000 • FermiLAB: from 30 NT domain to a single W2000 one. • with multiple organizational units. • Investigate possible NT4 to Active Directory migration tools. • LAL / CNRS is migrating the NT4 domain to W2000. • Initially in mixed mode (VMS PathWorks constraints). • Keep the DNS primary server on UNIX. • No plan for a wide upgrade, but new PC in W2000 by default. • CEA/DAPNIA/SEI are implementing a pure W2000 domain. • Try to use the max. of W2000 functionalities. • Products are assigned or published with Group Policy. • Startup scripts for computers and users. • SLAC is heavily based on NT4 WTS. • Testing & implementation of W2000 native Terminal Services and Application Deployment Services is planned. Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  6. Windows 2000 Deployment • RIS limitations • RIS is not able to install Server version of W2000. • Concurrent Remote Installations can overload the server. • Unicast based actions slow down the process of multiple installations. • Unable to control disk partitioning during the installation process. • Retrofitting drivers in the image is very complex. • PowerQuest Drive Image Pro • Faster than RIS for single and multiple installation • RIS 1m21min, 4m48min; DI 1m12min, 4m14min. • Meaningless auto generated computer names Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  7. Application deployment/support • Beyond MSI • Group policies may work in a small scale environment. For large sites the extra features of SMS (v2.0 +SP) seem to make it the most attractive. For medium sites third party solutions such as Delta Deploy have more functionality than GP with less complexity than SMS • MSI is NOT an application manager. • Focus was installation process, not software management • Targeting in a pure Win2000 environment with Active Directory and GPO • High complexity • No targeting for Windows NT 4.0 and Windows 9x Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  8. Security & Authentication Issues • Compatibility issues in mixed environments. • If you are in mixed environment, the least you should do is get rid of LanMan Hash until Microsoft solves Win2K with NTLM v2 problem. • Common password service • JeffessonLAB: jpasswd • Kerberos 5 support ? Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  9. Web Services • Namespace, ISP like Web services • Web is more than HTML ! • File services • XML – the basis for distributed services – • SOAP Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  10. Other Utilities • Windows Terminal Server • At SLAC is used heavly • Clients on Terminals Windows CE based (WYSE) • Users are happy • Is not clear if the version embedded in W2000 is able to speak to Citrix clients • Exchange • PROS • Encrypted passwords, Secure web access, Database for messages • In addition it had calendar and virus scanning add-on • CONS • Eudora does not support SSL (and Exchange does not support Kerberos) Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000

  11. HEP Applications • Discussion triggered by Gianni. • The approach for the SW development is very different from W & U environments. • The GRID MiddleWare can be the response? • Applications can be written in a architecure independent way? • But there are aready some physics applications (ROOT for example) that is Win ready.
