1. RHUL1 Site Report Royal Holloway Sukhbir Johal Simon George Barry Green

2. RHUL2 Hardware ~30 Desktop PC’s ranging from 300 MHz K6 to XP2400+ Athlon mostly RH7.3, few WinXP ~12 Desktop PC’s 450 K6 – 1700 Athlon for ATLAS test bed RH7.3 ~24 Laptops both personal and department-owned RH7.3, 9, Fedora and WinXP ~6 PC servers RH7.3 (one RH 6.0) – mostly Athlon XP2000-3000 NFS, NIS, Firewall, Web Server, etc. 1 PC server RH7.3 with 64bit kernel on a Athlon64! as yet unsuccessful with Fedora 64bit ~2 PC servers Windows2000 Native Active Directory Terminal server (Citrix/ICA), Office, VB

3. RHUL3 Hardware continued.. 3 Raid servers 2.0TB array running RH8 (2 will become SE’s for new Farm) user scratch volume, home backup 1 Sun E450 Solaris8 Home (NFS) 1 Sun E250 Solaris8 Babar 1 SunBlade100 Solaris8 Mentor (CAD)

4. RHUL4 Compusys Farm 75 nodes2x Intel Xeon Processors 3Ghz 80GB HDD, 1GB RAM RH7.3 1 Master node2x Intel Xeon Processors 3Ghz 2x 80GB HDD, 2GB RAM RH7.3 Failover master node, 1 AIT2 tape unit HP gigabit ethernet throughout Console switches Good experience with Compusys RHUL Grid: 1 LCFG install server 1 CE pbs interfaces with pbs on master node of farm 2 SE 2.0TB each (to be installed next week)

5. RHUL5 Network Mostly Switched 100BaseT to desktops, 1000BaseT to servers Connected to college 2Gb ring via 1Gb switch on VLAN We are not firewalled by the college. Our firewall is a default DENY setup Laptops on 11Mb wireless network and 100Mb ethernet Currently experimenting with a gateway/router for a private wireless subnet for laptops Network security College suffers badly from worm epidemics Mainly due to badly managed staff machines at home: connecting via VPN from home or infected laptops brought in to work We haven’t had an incident (yet) on the HEP network, but if the campus network is overrun we still suffer the consequences

6. RHUL6 Issues: Hardware Specification Laptop/desktop - Linux compatibility Laptop updates - use of Microsoft SUS for Win OS’s and Yum for RH Laptop backup strategy Security - physical and network Linux releases

7. RHUL7 Projects: Replacing aging desktop PCs Replace 15 machines at once to get economies of scale Buy pre-built to our spec We decided on the following spec: K7VTA3 (full ATX motherboard) 1.44 MB Floppy AMD AthlonXP 2400+ CPU 256MB DDRR PC2700 RAM 40GB HDD 7200rpm 16x DVD ROM Radeon 7000 AGP 32MB graphics card Competitive quotes from companies like: Midland, BBN, Savastore, Nsysonline, Aligatortech, Pentathlon Cost <£200 each 5x PCI slots, 1x AGP slot Supports AMD Athlon XP CPUs up to 3000+ 333MHz FSB on board 10/100Mbps LAN on board audio 6 USB 2.0 Ports (4 at rear, 2 at front) 2 DIMM Slots (max. 2GB) DDR PC2700 1x Serial Port, 1x Parallel Port

8. RHUL8 Projects: Remote windows update management: Critical security issue for group laptops Tried MS SUS1 (too buggy) and MBSA (useless and discontinued) Waiting for Microsoft SUS release 2 which seems to have a lot more features and is more stable for laptop updates. Looking at Microsoft Services for Unix (SFU3.5) Provides interoperability of Active Directory and NIS NFS  Alternative to Samba?

9. RHUL9 Linux versions RedHat 7.3 updates from Fedora and CERN seem to work well looks ok for the rest of this year RHEL3 cost still an issue, even though the lowest price has come down (workstation + educational price + no support) admin effort of having to deal with paid licensing at all concern that future CERN deal might not have the right pricing for us Scientific Linux (SLC) one test workstation set up, so far so good seems like a perfect HEP solution planning to use this on new desktop machines this summer (hardware support for new machines in RedHat 7.3 is now a problem)
