I am new to SCSI hardware and have a question concerning the different types
of hard drives available. I have an old Sun IPC that I want to add a bigger
drive to. It has a 50 pin connector. Will any 50 pin SCSI device work or
does it have to specifically be a scsi 1 drive (i.e. will an "ultra SCSI"
device work okay?)

Would you be so kind as to tell me how you did it?
Yesterday I bought a HP ScanJet IIcx with a
Symbios Logic 53C400A SCSI-Adapter.
Question: could I just re-compile my 2.2.10-kernel
with the Symbios Logic 53C416 SCSI-adapter to make
my 53C400A SCSI-adapter work?
Please reply this message... it would be a big
help :-)

Is that an ethernet connection? You might just have to pppd and dhcpcd.
dhcpcd could find the way out, and dns servers, using your pppd
connection
for gateway/default. Then data could come back on eth0, satellite.
I've heard from people who use DirecPC and linux.

Well to start off, make sure to get a machine with IBM harddrives. Their
DeskStar series is
so quiet that the first time I installed it, I was worried it was not
working since I couldn't

I took a chance on a generic V.90 cirrus-logic chipset external voice/fax/data
modem recently, and it seems to work fine under linux and windoze (OSR2.1).
Well, once I got windoze to stop finding two modem devices...
External is the way to go now, since they're so cheap. It seems to get
slightly better throughput than internal (less interference), although you
need a spot for the external power supply, and it takes up a serial port.
Connections/speeds above 28k seem to depend on (sometimes quite variable) line
conditions, however the linux ip-masq gateway seems to have a faster and more
solid connection than when I had the modem on the windoze box. I've gotten
ftp downloads as fast as 4.9k/sec, but it depends heavily on the modem
handshaking and traffic, both local and remote.
Anyways, the generic cirrus logic was about $34 plus shipping at the Geeks:
http://www.compgeeks.com
They have some excellent deals on other stuff too. They don't have a large
selection, certainly not compared to HardwareStreet, BuyComp. or A2Z, but
they're pretty much my favorite vendor overall.

Well, my interest in fluid dynamics is small, but I do do a bit of 3D
rendering, application development and kernel hacking for fun.
Here's a comparision of limited worth (all tests with 2.2.x kernel from
same distro):
486DX66, 32Mb Ram, 2Gb
- make zImage modules modules_install: >10 hours
- compiling ssh: 12 hrs
- creating 2048-bit ssh key: 10 hrs
- text-mode 3D rendering, 3 objects, one light source: >1 day (until
interrupted in boredom)
- one setiathome work unit: ~5 days
Dual PII-400, stepping 2, 256Mb, 8Gb
-make zImage modules modules_install: 4 minutes 23 seconds
- compiling ssh: <5 minutes
- creating 2048-bit ssh key: <4 minutes
- visiul-mode 3D rendering (3 objects, one light source): 3.5 minutes
- two parallel setiathome work units: 8 hours
The fact is, anything that is compile or math intensive will do better
on modern hardware. Why even debate the fact?
If the question is "do most people need this power?", the answer is
probably "no". Does anyone need a car that goes 150MPH? Then again,
having a car that can cruise easily at highways speeds, has all the
perks (nice stereo, comfy seats...) is really nice.
Similarly, having a home computer that can ramp up the cycles when you
need them, without paging constantly, is also really nice.
When you reach a certain age in the computer business, there are certain
things you no longer put up with. Old hardware has it's place: as a
DHCP/DNS server, non-encrypting firewall, file-server (if properly
tuned). Being a useful desktop tool for me? Not a chance.

Do you mean stupid winmodems, or modems that store ISP phone
numbers and maintain connections? I have an intelligent net hub called
Rampnet Webramp, connected to PC ethernet card by 10BaseT half-
duplex, and it can dial up to three analog modems and alias up to four
PC's to use 1-3 modems as one virtual modem. For people who can't
get DSL or cable modems yet, it's OK. Wanna buy it cheap?

Since Bartek said it was going to be a file server *and* application server it
would help to know what/which applications he'll be running on it. If it's
only purpose is to serve files then yes, a single CPU would work ok. Depending
on the application that will be running in the (application) server's memory
(SQL DB, Mail, X, etc) might call for a multi-CPU setup.

Try using mount /dev/cdrom. If /dev/cdrom is defined in your /etc/fstab it
will mount at the pre-defined mount point (normally /mnt/cdrom). If it's *not*
defined in the fstab then type mount -t iso9660 /dev/cdrom /mnt/cdrom at a

No surprise. Please use a more recent distribution - RH 5.x doesn't
know anything about the partition type "f" (which is Win9x extended).
If that's not an option, at least use an updated fdisk versionxn.
