Svend, you sent me in the right direction. Thank you.
Based on what you suggested, I deleted the extended FAT32 partition on
the second hard drive and created a single FAT32 primary partition.
(Since it's all data, I'll divide things up using directories instead
of partitions.) I booted to Linux and returned to Windows without
apparent problem.
In posting my original question, I had missed a crucial fact that your
suggestion uncovered. In previous partitioning schemes, I had an
extended FAT32 partition on the first hard drive (presumably type 0F);
in my current scheme, the extended partition on the first hard drive is
type 05.
This experience raises an additional question.
Where does one go to learn about the bugs in Windows or Linux?
Thank you again for your help.

Hm, so maybe the problem isn't really the major/minor device numbers.
On my system /dev/fd0 is major 2, minor 0. Check this by 'ls -l
/dev/fd0'. You should get something like
brw-rw---- root root 2, 0 /dev/fd0
So if that's correct, then try Equinox' suggestion for making sure the
modules are loaded.
If that fails, then there are probably other things to try, but what's
worked for me in the past is to rebuild the kernel. I had a floppy
drive that worked fine under Windows but never did work under Linux
(drive light came on, but I never could mount anything). Finally I
rebuilt my kernel and the problem disappeared.
Good luck,
Andrew.

I have a windoz box behind my linux system with a firewall setup. My
problem is that I can't get the windoz system to send the completed WU
through my linux system. Anyone have any idea as to what I am
overlooking? Both of my linux systems have no problems sending theirs
just the windoz box.

I am using a USRobotics ISA modem and am trying to set it up so that I can
use it to connect to my ISP. I have gotten to the point where I can use
minicom to manually dial to my ISP and log in, but of course cannot start
PPP that way. When I try to use pppd, however, chat gives me the following
message:
Can't get terminal parameters: Inappropriate ioctl for device
I have double-checked the connect script to ensure that it is using the
correct device (/dev/ttyS3). I presume that the message means that
something is not configured correctly with regards to the serial port, but I
am not sure what I need to do to fix it. If someone has some insight into
this problem or can point me to some pertinant documentation, I would
appreciate it.
Thanks,
Daniel Harding

Daniel,
I am just as much at sea about Linux as you (see the posting above yours),
but I have a USR ISA modem, too. You mentioned ttyS3 - are you running the
modem on Com 4? Com 1 is ttyS0, Com 2 is ttyS1, etc. Also, check the
jumpers on your card. If it is like mine, you can configure it for the IRQ
and the COM port. Usually, modems like Com 2. Could ioctl mean your I/O
ports are different than you think?
At least you can connect to the ISP - all I get is "modem locked"!
Hope this helped, at least a little.
Regards,
Malke

Your current working directory . is not on your command path, so to
execute a file named "IamExecutable" type "./IamExecutable".
You could also add . to your search path (environment variable PATH),
but this is considered a risky practice due to security considerations.
In any case, before running any program you should read, at least, the
README that accompanies the executable.

Date: Mon, 03 Jul 2000 04:08:19 GMT
Actualy the "zero" subnet is covered by a somewhat newer RFC. At one time it
was not permitted. As such, some older devices (some routers, etc) may not
understand it correctly. Having said that, almost all newer devices and hosts
have absolutely no problem with the zero subnet. Just make sure you don't
have any really old stuff on your network making routing decisions.
Even newer devices may need to be configured to support it properly (though
almost all do by default.) For example, cisco's IOS has an ip "subnet-zero"
command to explicitly enable/disable this support.

No, it's definitely not a Winmodem. I wouldn't have one of
those things and I know the difference between the two.
The funny thing is, it's Plug 'N' Play, but Win98 didn't detect
it. It detected something there, but didn't recognize it as a modem.
I had to have it detect it as new hardware and then use the
drivers on the CD to get it working.
Windows says it's on Com3, IRQ5. Don't sound cards use IRQ5?
Maybe that's why SAT won't detect it, they're both on the same IRQ.
I don't know if there are jumpers on the card to hardwire it to use
certain com ports and irq's. I'd have to dig it out of the computer to
see.

Although I'm not going to try to guess the security implications, one way
would be to do this..
chmod 4555 wvdial
This would make it run as whoever owns it (root) regardless of who runs the
command. Anybody could run it that can sign on to your system. Another
choice would be
chmod 4550 wvdial
Which would do nearly the same thing, but then only members of the group
assigned to wvdial could run it.. but it would still run with root rights.

Hi lazy one!

>From practice with this OS, there are NO teachers that can teach you
things that will be applicably in all situations. If someone will
promise to make you an instant guru, take it with a very big rock of

My suggestion: invest in few books on unix/linux administration and
spend the time overcoming problems as they surface. In short time you
find that things are getting simpler and you have proper references if
you run into walls.
And remember, Linux is for having fun...

Hi Marcos,
once I tried the following started by a cron job early in the
morning :
dd -if=/dev/sda -of=/dev/sdb
This made an exact copy of (SCSI) drive A to drive B.
Most important thing was, that drive B was NOT mounted into drive
A's file system. When I unplugged drive A the system came up without
any probs on drive B (besides the fscheck during bootup). The second
drive was exactly the geometry as the first one. I don't know if it
will work with your configuration, but I think it should.
Be aware that this solution only works for backup purposes where you
want to keep downtime short for a server without too much loss of
data.
