## Main Resources Changes

- More Linux CPUs
- 25 dual Opteron 2,2 installed (IBM e325, 1U)
- Linux upgrade to Scientific Linux
- Currently installed on all new machines (i386 or amd64)
- Proposed on desktop, preconfigured with Kickstart
- Network : new switch with 10 Gbs uplink
- XtremNetworks Summit 400 (48 Gb ports)
- Used by Opteron farm
- Plan to replace central switch (Cabletron SSR 8000) next year

## Mail Service

- Authenticated SMTP in production
- Required to relay through LAL mailer (roaming users, home access...)
- Based on Sendmail + SASL
- Password management integrated in npasswd used for NIS passwords
- LAL extensions to npasswd
- Spam : Bayesian filtering useful
- Filtering efficiency : ~95%
- Slow learning curve for this filter (~3 months)
- Need to feed filter db with undetected SPAM once a month at least
- New patterns appear on a regular basis
- Undetected SPAM collection need to be automated ?
- Plan to move to Cyrus v2
- SIEVE for filtering at message delivery (server based)

## Windows Infrastructure...

- IN2P3 forest in production
- 11 labs in production
- All IN2P3 labs should participate
- No problem so far...
- Move of LAL AD domain to IN2P3 forest delayed
- Planned this summer but time is missing
- Challenge : transparent to users, preserving GPOs
- By the end of the year ?
- Pressure growing as this is requirement to use national repository for mechanical CAD/CAM (CATIA SmarTeam PDF)

## ... Windows Infrastructure

- SMS : key management component for LAL
- Complements AD based tools
- Deployment of security patches, SPs and system upgrades
- SUS feature pack (presented at Edinburgh meeting)
- Based on SMS inventory and logging capabilities (push model)
- Plan to upgrade to SMS 2003
- Better integration of SUS features
- Integration with ActiveDirectory
- Virus attack caused by a problem in CISCO ACLs
- Few machines affected (unpatched machines, proactive patching critical)
- Checking is time consuming...

## Printing : Multi-Site Printer Wizard

- Based on CERN Printer Wizard (Windows only)
- Management of LPR based printers by an unprivileged user
- Printers described in a central database
- Support any LPD/LPRng server
- Now supports the concept of Site
- Work done in common between CERN and LAL
- Allow to use the same client on several sites
- Each site has its own database of printers
- In production at LAL since last summer
- Very appreciated by our users involved in CERN experiments
- Could be used/supported by other sites to help traveling users

## GRID

- Strong involvement from LAL in EDG / LCG / EGEE
- LCG Tier 2 (plan to do in common with DAPNIA)
- 4 FTE including PTB leader (Cal Loomis)
- Still 1 additional open position to fill (2 years European contract)
- Fabric : currently 40 CPU (1/3 Xeon 3Ghz, 2/3 Opteron 2.2 Ghz)
- Recent machines running SL
- Current focus : middleware deployment, Quattor integration
- XtremWeb : a P2P computing project
- Partnership with LRI (Orsay, computing research) for 4 years
- Significant resources : 30 CPUs (Xeon 3 Ghz, Opteron 2.2 Ghz)
- LAL interest : use of P2P resource as a fabric via OGSA
