1. Glasgow status A.Flavell For HEPSYSMAN July 2004

2. Overview This does not cover SCOTGRID, although this is now a major part of our effort Group/Department/Faculty/Campus... Windows Linux Network Mail Web

3. Group/Dept/Faculty/Campus There's a long history behind this, in which, way- back, Particle Physics was basically the supplier of computing, email, local networking, and nobody trusted anyone else to provide... Much of what we do now is just ordinary, and we know we ought to stop micro-managing, and get the benefits of scale But it's easier said than done! This thread runs and runs...

4. Group/Dept/Faculty/Campus Some activities migrated up to Department level Some activities migrated from the centre down to us... (but not very much, TBH) Recently we've been steered towards joint efforts within the Physical Sciences Faculty This is in effect an extra layer, that previously didn't get involved in computing matters. We find some useful common interests, but also some substantive differences.

5. Windows Campus is traditionally Novell-based Group and dept use MS Networking Faculty is partly the one, partly the other Campus standardised on Windows/2000 desktops, with XP deferred until later. Campus suppliers must deliver Win/2000 Research groups spend their money differently: some now buy machines with XP installed and no /2000 support

6. Windows (2) Campus offers support for a "Standard Staff Desktop", but the dept has its own ideas... Lack of specific training means we have to support Windows systems with multiple fractions of an FTE, but don't know how to use Windows management effectively, so we seem to get all the disadvantages of a complex Windows setup, but few of the benefits of scale.

7. Windows in practice Existing "NT4" domains being dismantled Couldn't wait for campus to do Active Directory, so the dept "went it alone" Research groups migrated from their flat NT4 domains to OrgUnits of AD domain The move being completed right now Alongside that, NT4 machines being upgraded to Win2K or given a decent burial

8. Linux Most particle physics desktops are RH9 Some CDF are Fermi Linux (7.3) Servers use various Strong interest in Scientific Linux, but only trial installations so far, no "real" users Campus said no to a RedHat campus license Worrying about complexities of license management

9. Linux - various points CUPS printing does some odd things Hoping to get GnomeMeeting organised on more than just experimental basis Is there a neat way to install ALSA?

10. Dual-booting? We tried dual-boot desktops in the past Not a success. A given system tends to stay in one OS, and the other one decays But laptop users insist on both Department is treating laptops as hostile PPE hasn't gone that far yet Most PPE desktops are managed Linux Minority are Windows (2K, still few NT4) Some people have one of each

11. Cross-access Windows systems have eXceed, or more recently trying Cygwin/X. Well-used. We didn't mess with Linux access to Windows till recently Some users want rdesktop to access remote Windows systems We still don't offer Windows service locally in that way Windows users access Linux filesystems via Samba

12. Network Network: no major problems to report! Excellent network on campus, good connectivity to Internet Equipment being upgraded to meet Scotgrid and eScience needs Campus web cache can be a problem... Future: campus thinking of "default deny" policy; for now it's ad-hoc deny, including deny port 25 in and out except registered mail servers

13. Email The dept set up email (exim) with spamassassin etc. some years back Various research groups joined: now covers essentially the whole dept. Excellent results, but quite a lot of ongoing effort Campus central mailer then introduced spamassassin etc, with lots of useful discussions both ways Central service is now pretty good in that sense, but mailbox limit is far too low for some of our users

14. Email One proposal was to join the central service while funding our own mailbox storage......but no! We've been told to provide a Faculty-wide mail service instead. With of course the usual multiples of fractional FTEs to support it. Details are still to be worked out.

15. Web Central policy is to consolidate web servers centrally for security, and also to impose their idea of accessibility to meet DDA etc. But many detailed reasons why people justifiably need to run their own web servers as a tool rather than as a publicity vehicle Some academics insist on providing their own web materials while refusing to meet DDA requirements ("too busy") Some content is frankly impossible to meet DDA requirements anyway

16. Web (2) So the web is in tension, pulled in several directions. Hard to predict how this will develop.
