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

2. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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

3. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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)

4. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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

5. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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.

6. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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

7. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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

8. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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 ?

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

10. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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)

11. Report Enrico M.V. Fasanelli & Gian Piero Siroli Commissione Calcolo - Roma 14 Novembre 2000 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.
