SGIs

There is a SGI INDIGO2 with quite enough power, working as my printspooler (using CUPS). The scanner is also attached to this machine, the software I use to scan is SANE. Anybody who owns an Indigo2 will tell you that they have one of the finest graphical workstations ever built. And it isn't totally obsolete yet either, as the Indigo2 can still hold it's own against more modern machines, thanks to an upgradable architecture that can, in some cases, allow the machine to use the powerful R10000 processor, the same CPU used in the much newer (and much more expensive) SGI OCTANE machines, which high-end places like Pixar and Lucasfilm still use. The Indigo2 was positioned in the middle of the SGI lineup, between the low-priced "Indy" workstations, and the much more expensive servers such as the "Onyx". As such, it needed to fill the tough role of being somewhere between those two extremes. An other SGI is my old INDIGO, but the R4000 processor is out of style. The Iris Indigo was a graphical UNIX workstation produced by Silicon Graphics Inc. during the early 90's. Many think of it as the best designed SGI until recently when the O2 arrivedThere is a INDY with a R5000 processor.When the Indy first arrived on the scene, it was tantalizingly close to attainable. Marketed as a "cheap" Unix workstation, it was SGI's push to get people to use their machines for all types of graphics work, 2D or 3D. For it's time, the machine is pretty revolutionary. It was a low cost Unix workstation that excelled at 2D graphics (it's 3D capabilities were pretty minimal), was reasonable fast (even slow SGI systems seem fast because their graphics cards update the screen so quickly), and featured an ISDN port, a built-in camera, videoconfernceing capabilities, and all kinds of cool stuff. Starting with the R4000, the processors moved up the range to also include the R4600, the R4400 and the R5000 (yes, the 4400 came after the 4600, I don't know why). Graphics possibilities ranged from low end 8bit color to 24bit to 24bit with some 3D capability. The only task for my indy is to operate the INDYcam. I'm not so photogenic, so its switched of most of the time ;-) But the script I wrote to drive this cam is interested, take a look to it.
All my SGIs run IRIX Version 6.5.

Server

A brand new Pentium IV with 512 MB RAM is in function since Jan. 2004. There are so many tasks on that maschine, this document is hosted there for example.

SMTP-Server
IMAP-Server
MYSQL-Server
WEB-Server
vbox answering machine
nameservice (bind)
DHCP Server
NFS-Server
huge HOME directory
CD burner (SCSI)
News-Server (leafnode)
Big Brother monitoring
mp3 streaming server
vnc-Server

It provides also a self make web frontend to my answering machine vbox. There are 2 sound cards build in, also a ISDN card

Firewall

The gateway and the firewall is running at an old Toshiba 486 notebook. Instead of a hard disk drive there is a SD RAM card with 512 MB build in. Two PCMCIA network card handle the access to the internet and to the intranet.

accessories

There is an old but sufficient HP5P scanner with SCSI connector. I bought my 5p in 2001 and it still works great. Speed is not impressive to me, but Good Clear Scans with Good Rich Color makes this scanner rock.

A very old HP4L laser printer, driven by CUPS is unfrequent used,, max. 300x300 dpi

The wireless lan access point gives me the freedom to move around in the whole flat.
A LCDisplay controlles some operating values of the server. LCDproc is a piece of software that displays real-time system information from your Linux/*BSD box on a LCD. And a 3COM switch connets all parts together. A DCF77 time signal receiver care for the propper time at the server, a ntp-server provides the time information to other computers here. DCF77 ist ein Zeitsignal und wird auf der Normalfrequenz 77,5 kHz als Zeitinformation in kodierter Form ausgestrahlt. Die Sendeleistung beträgt etwa 50 kW bei einer ausgestrahlten Leistung von etwa 30 kW in einer Reichweite von ca. 2000 km im Umkreis um Frankfurt/Main bzw. Mainflingen.
A TNC3S, a modem for 2-way radio is intended to keep in touch with other radio amateurs. Im TNC3 sind zwei Modems eingebaut, eines mit 1200 Baud AFSK und ein 9600 Baud FSK Modem. Beide Modems werden vom TNC3-Controller gleichzeitig angesprochen: Auf dem Monitorschirm sind die empfangenen Daten beider Modems zu sehen. Connects können wahlweise über Modem 1 oder Modem 2 gestartet werden. Die Unterscheidung der beiden Modemports erfolgt durch die vorgestellte Portnummer

Notebooks

Beside the 486 Notebook working here as my firewall there are some more noteboos here. Most of them old and out of style. There is a 1988 Toshiba XT1000 notebook, a satellite 310 on which I wrote Linux für Onliner and some more modern notebooks like my Dell Latitude.
