  1. CERN Messaging Infrastructure Status and next steps Arnaud Taddei HEPiX RAL April 1999 Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 1

  2. What’s new since April 1998? • For those of you who were present at the Mail Session at HEPiX Lyon • At CERN, the messaging infrastructure unit moved to a new group IT / IA Internet Applications • The service produced some interesting new results • The rationalisation of the system reached new steps • At the end of the year only a few hundred users will not use the service • We are asked for more features • We are asked to make the servers « rock solid » BUT • We are missing 1.5 « FTE » since September 1998 Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 2

  3. The new CERN IT/IA « Internet Applications » group • Group Leader: John Gamble (retains his role as CERN Computer Security Officer) • Group Mandate(From the memo creating the « Internet Applications » Group.) « Consolidate requirements capture, evaluation, implementation and support for services, tools and methods for information sharing and collaborative work over Internet-type networks » • Group Structure: 3 Sections • Collaborative Multimedia C.Isnard • Messaging Infrastructure J.Richards • Web Services F.Fluckiger Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 3

  4. Futures Collaborative Multimedia • LCB PEP on video-conferencing (tele-meetings), • Consolidation of Video-on-demand and recording facilities, • Startup of pilot Net/Web-casting server and facilities. • Make these generally available Current Tasks Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 4

  5. Messaging Infrastructure • Run the central Mail servers and mail gateways, • Provide Listbox and user mail management tools, • News servers, • Calendaring service, LDAP deployment Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 5

  6. Web Services • Run the central webservers, and CERN search engine • Support users wishing to setup and author web sites, • Offer value-added tools and services for site management. • Increase service acceptance in the community and reduce number of independent web servers. Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 6

  7. Other Items • Find out what our community needs, in terms of collaborative tools, that we can provide - on a reasonable time scale. • Rationalize Netscape Support. • Introduce a Certificate Authority for CERN. • Develop the web service so that users want to move their pages to it. Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 7

  8. System # PEMs Terminated VMSMail 1300 only few hundred users MSMail 1800 Summer 99 QuickMail 1500 end 98 AFSMail 4000? mid 98 Other Mail systems only a few hundred users Mail Servers status • Statistics • We integrated • mail4 in Spring 98 • mail5 in January 99 • The MSMail migration is a success! Thanks to P.Hagen. • 1000 people migrated in a few months, 0.5% direct problems, Only 200 people to migrate • Server side rationalisation done • Netscape deployment successful … eventually • Registered users 12,000 • Number of PEMs 8,300 • Active users in 99 7,000 • Concurrent users 3,500 • Disk space used INBOX 25 GB • Folders 30 GB Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 8

  9. MARCH Project Status • We moved the first front to the User Support group • Documentation improved • http://consult.cern.ch/service/mail • User statistics tool designed, called WBUIS (P.Webb) • http://mailwww.cern.ch/userinfo/wbuisform.html • Access to auxiliary commands via the web instead of telnet (M.Ganz) • http://mailwww.cern.ch • users can change password, vacation, quota, folders statistics • Training offered to local administrators to support Netscape • Spam fighing is taking up to 50% of a senior administrator ’s time (D.Wiegandt) • We launched several studies which will come to conclusion by Summer 1999. • We got a new staff but we are still missing manpower since September 1998. In addition our senior system administrator retires end 1999! Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 9

  10. Oracle Mail Servers - Logs - Tables - File Systems - Forwards Web Mail reports Next Steps - Short term: - increase file systems, - use reserve, - load balance users - Medium term: - increase disks capacity - Long term: - use single message store IMAP servers, - develop shared folders, - develop e-archive facilities • Consolidate server side in 1999 • Rationalisation of the backup system • Upgrade servers for Y2K issues • Disk space management is a Short/Medium and Long term issue • Statistics package (collect all data through Oracle) • Offer new services • a much richer LDAP service • HEP wide, more data, roaming, authentication • Offer a calendar server • Client support • Netscape 4.5 including Mission Control Desktop • Pine 4.10 Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 10

  11. Netscape 4.5 • Release rates from Netscape and mozilla.org • 4.5 released in december • 4.51 beginning March (one week late on announced schedule) • 4.52 announced to be released • 5.0 this year (complete rewrite from open software mozilla.org) • What ’s new in 4.5: • key improvements in the mail part … but still not enough http://consult.cern.ch/service/mail/problems/netscape-4.5.html • We are trying Mission Control Desktop to facilitate deployment configuration and CDs for home users • By putting the right cofiguration file at the same place of the executable you can tell the client to contact a Java Script in which you can program the initial configuration. http://consult.cern.ch/service/mail/clients/netscape/v4.5/AutoConfig-1.0.html • See as well the status at CERN http://consult.cern.ch/service/mail/clients/netscape/v4.5/status.html Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 11

  12. LDAP Status • Last year P.Matousek (CERN) and H.Jamet (IN2P3) worked together on a first o=HEP, c=NET LDAP service • 2 papers were issued • The Global Directory among HEP sites P.Matousek CERN and H.Jamet IN2P3 • LDAP replication at CERN P.Matousek CERN • deep state of the art analysis • important comparison between referals and replication • proposed HEP person schema • From CERN, somebody with the right knowledge can access RAL, IN2P3 and DESY LDAP services today! Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 12

  13. LDAP Status at CERN • P.Matousek left CERN and we are missing manpower. • This slowed down everything. • However reallocation of manpower and move of mail support to US group helps! • P.Matousek left • a very good setup to incorporate more data with a complete description of how to rebuild LDAP service with more data and better structure. • We are scheduling when to do the change • New requirements are coming • we are asked to start calendaring service and • our users need roaming access in particular with Netscape 4.5 • Netscape bought by AOL + Sun will impact the server suites. Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 13

  14. LDAP Plans at CERN • Evaluate « distance » between different schema • reverse engineer Netscape LDAP schema for supporting calendar and roaming • support of CERN yellow pages • support for authentication services (Sun Solaris 7 and 8 with LDAP server in the kernel) • others (group support, resource support, etc.) • Prepare a schema which allows other CERN units to « play » with it and gives support into a master server • work on the architecture of this new service • high availability • performance • access statistics Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 14

  15. LDAP at HEP: questions • Could we get an official mandate to investigate the opportunity and constraints for an LDAP service at HEP level • If YES, who is interested to contribute? Roles - we need so far: • a site to coordinate efforts: • could it be IN2P3 due to their progress in this affair and anyway they are already facing the problem? • to meet to agree on a product to release • a project leader to follow commitment and timetables • to review the impact, results how often services are used, publicity on each site, etc. • a forum/place where to put « expertise » answer/advice Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 15

  16. US Trip • As we are in a new study phase we need to explore a certain number of alternatives • In addition we have developed some expertise which interests some people • We have good contacts with certain key people in the Internet and Vendors community in the US. So we will meet with (scheduled May 99): • B.Yeager (IMAP grand father and designer of SIMS) at Sun Microsystems • J.Myers (designer of CMU and Netscape IMAP servers) at Netscape • Product managers of Netscape 5.0 (P.Trudelle ...) • M.Crispin (IMAP author), J deRoest and T.Gray at University of Washington • Our SLAC peers • We are still trying to find somebody in a big ISP and peers at • Microsoft for LDAP commitment • Netscape for Calendaring • We are concerned about the AOL/Netscape/Sun merge for deciding our next implementations Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 16

  17. Conclusions • Hopefully this year most of the initial MARCH mandate (end 1996) will be completed at CERN • This is raising new expectations and there are new technological atlernatives: We are facing new challenges! • We believe that some new developments/deployments should be clearly done with an HEP perspective ... • who is ready? • can we organize ourselves correctly? Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 17

  18. Miscellaneous • Who is dealing with anti spam at HEP.NET Arnaud.Taddei@cern.ch CERN IT/IA/MI HEPiX RAL 99 14th April 1999 18
