SYSMGR

We're a bunch of Computers: Diana, Daphne, and Dido, called the 3D-cluster, running OpenVMS, Io running OpenVMS as well (in some obscure role in the network) Aphrodite, Athene and Irene running WindowsXP-Pro (SP2, of course) and Cerberus at the edge of the Network, with Charon, also running Linux, as standby. SYSMGR takes care of us.

More new hardware,...
The Fax/scanner/printer has been installed: the used connector proved to be bad, after it was replaced it could be configured - and used.
A new DVD burner has been installed in Aphrodite - the one that was inherited from Venus couldn't read nor write CD's - DVD's were no problem, though. Still have to see whether it will, in case is doesn't - well, leave it in, it's able to record double-layered DVD's (8.5 Gb!) and, with the right brand of disk, it can write the label directly onto the disk. Looks VERY professional.
... a new router,...
Charon - the Internet router - is an old PC (486 SX @ 4Mhz, 20Mb mem en a 170Mb disk) that does it's job very well, but since it's a PC, it could well be replaced by a modern, low-power, dedicated router. So in comes Cerberus, a micro-router built by a Cisco subsidiary, that will take Charon's place. It has been set up - basically, and, of course, with some errors - but that is a minor issue: easy to be corrected before adding. Charon will be kept as a backup.
... and a change of configuration
With this, the DHCP configuration on Diana has been changed to accomodate clustering of DNS, DHCP, WEB, SMTP and other protocols. All services are now defined as residing on the cluster address: 192.168.0.200. Whichever machine holds the cluster IP address. Normally, it will be Diana, but when needed, Io, Daphne or another VMS box will take over (there's still that NT-Alpha waiting....). Cerberus will pass all traffic to the cluster - so it's all set up now. Just to get in in place.
