I am planning on setting up a web cam using the linux as a server.
Which cams are recommended for me to use? Would like something in color,
with decent optics. Don't want to spend an arm and a leg but will to get
something good.
I've got parallel and scsi interface.
Thanks

I have a Diamond Fireport 40 here in my computer at home. It works well.
If you have more money, two companies to look at are digitalscape (
http://www.digitalscape.com ) which has a good combo Ethernet/Ultra
SCSI board that I have in my computer at the office (but you must upgrade
the yellowfin driver from Donald Becker's latest to use the network part),
and IntraServer ( http://www.intraserver.com ) which is very supportive of
Linux -- when I had a problem with not having an up-to-date driver they
told me where to go to get a new driver, they didn't say "huh? Linux? Is
that a brand of air conditioning?".

Subject: Newbie question on modules and compiled support
Date: Sat, 13 Mar 1999 05:05:15 GMT
I'm having trouble getting lp support to work.
Every time I try to print something using lpr, I get the message in
/var/log/messages:
...kernal: lp: Driver configured but no interfaces found.
The only printer defined in printcap is lp. When trying to "cat
(text_file) > /dev/lp0 (or lp1 or lp2, these are the lp devices found
in /dev), I get:
device not configured.
How do I find out if lp support is compiled into the kernel? If it's
not, how do load the lp module? I've tried insmod lp and modprobe lp
but nothing happens other than an entry in /proc/devices for lp. No
entries in /proc/ioports or /proc/interrupts.
Do I have to do insmod w/ ioport and interrupt specified or am a
barking up the wrong tree? If I'm not, how do I do it? I can't seem
to find out how to specify parameters fo the lp load.
I can't seem to find the appropriate HOWTO and the only thing from
dejanews seems to think some probing should be going on. It doesn't
seem to be happening. Any suggestions welcome. Please help.

Your modem won't (ever ) work under Linux. I've seen posts of people who have
successfully gotten the 3Com cards to work a both speeds so there is hope for
that, but I don't use that brand, so I can't be more specific. I think you may
be able to specify the parameters for that interface in the linuxconf utility
that was included in RH 5.2, if your are using that distribution, and others may
have similar utilities?
Thanks for the info on vi -- I guess it's time to update my sig file -- That sig
came about because 2 weeks ago, when I first tried to install Linux, I didn't
even know the basic commands for the Unix command line, and couldn't even get
access to any of the "online" help with the system down, and/or me not knowing
where or how to look. I managed to start an edit session with vi to edit my
/etc/passwd file for my user account, and couldn't get out of it, so I rebooted
with my install disk, and reformatted, and started from scratch, rather than
deal with maybe needing to repair the filesystem. I've come a long way in the
past 2 weeks though :-)) Samba and DHCP are my next projects to figure out...

I bet that one is, though...
I've never run across a Rockwell chipset PCI one that wasn't--both of the other
PCI modems that claimed to be hardware based were using different chipsets,
weren't they? [The most recent posting of one listed a Lucent chipset, and the
other one is the Multitech?]

If I may be so bold to repeat a reply that I made to an earlier post
(easier than retyping):
----
I've worked on a number of SMP machines from a dual PPro/200 to a $500k
quad-processor HP monster. Currently have two at home (dual P-II/400 and
dual P-II/233). Linux provides strategic support for my businesses. (I
threw out WinNT because of cost and instability.)
The main benefit that I've seen with dual CPUs is that the machine can
handle a much higher workload than a single CPU. Linux mas matured much,
especially with the new 2.2 series kernel. The new kernel is
multi-thread safe. I don't notice any real slow-down on my dual 400's
until the load reaches 20-30. Usually the disks are going crazy.
You won't notice the machine running faster per se, i.e. one program
running all by itself. However, if the machine is running more than one
process, there are two CPUs to handle the work.
For example, whenever I compile a program, I use "make -j3" and make
will start two processes, each one compiling a different source file
simultaneously, if possible. Here there is a speed-up. I just compiled a
new kernel for my firewall. It takes ~8 minutes start-to-finish if I say
"make" (one CPU). If I say "make -j3" it takes ~4 minutes to complete.
One thing to be aware of is the fact that your disk drive may become the
bottle neck, especially if you only have one hard drive. I have four
hard drives in the dual 400's. If you do a lot of reads from one disk,
multiple mirrors can give a big improvement in reading (not so when
writing). For reading large files, striping can help some, too.

A single process would have to use multiple threads to take advantage of
SMP. Otherwise it is impossible for the kernel to somehow "know" in what
ways a program can be parallelised. In short, it's all in the
programmer's hands.

That depends on what you do. If you're running as an X server, no. If
you're running a busy web server, probably yes.

Yes, they work nicely.

Possibilities are limited only by where you can shop, and how?
Phoebe makes a decent ISA modem w/jumpers that I was able to get for about $45

don't know what your options are on that??) Just so happens that there is

This isn't as unusual as Dan presumes. The Apple Color Printer
(actually a Canon BJC8xx sold with a black apple logo screened on
the front) was also a SCSI printer. (It had SCSI and parallel
connections on back). I believe that the SCSI specification has
standard device control conventions. Original SCSI spec was
limited to commands for reading, writing, rewinding tapes,
sending commands to disks, but a much broader set of commands has
been implemented over the years. I'll wager that those commands
plus the known bitmapping datastreams used by these manufacturers
on "standard" printers would get one 98% of the way there...
I'm a hardware person rather than software, but as the owner of
an Apple Color Printer, I'm interested if anyone works out the
solution for this issue. (My printer is now only used on Wintel
machines via parallel port and a fairly lousy Windows driver for
the BJC820.) Engineering plots on this 11x17", 360 dpi printer
were wonderful off of MacOS.
