I don't understand. Just click on your package manager thigmie, point

There is no problem.
 

It's a silly question. Like asking how to dot THIS i. The same way you
dot any i. Install the "missing" software the same way you install any
software. Run your installer/package manager, and that's that.

You have a whole manual that comes with RH 6 that tells you how to do
that! But it's there on your admin screen anyway. RH 6 was bad that
way.

Debian ISOs on Bittorrent

Not sure about debian but why would you want to use Bittorent?
From what I saw it has potentional to be a backdoor into your system.
Especially if you are running it as root (really a dumb idea but
sometimes.... you do the dumb things, we all do.)
I go straight to the Distro's home page or mirrors, mirrors
are preferred, and grab the .iso directly. Its faster that way and your
system's security is not compromised.
Ditto with the other peer to peer software including
gtk-gnutella and mutella (console based p2p client)
BTW. did you know you can get Linux ditros using Gtk-gnutella
and Mutella just as easy as using BitTorrent? I have done it a few
times myself. Ditto with txt/ps/pdf files as well as .mp3/.ogg files
IMHO, I like Mutella in console better as it works good on a
low resource box.

People I know the answer now!!!!


It was stupid of me of course!!!
In de windowsXP(Professional)-PC I am sharing a whole disk!!
I only want to mount(on linux) the map named Pictures(from the
WIndowsXP-PC).
This disk has the label name "Over(G):\" in windowsXP
so the path to the map I want, is seen from the network as
Over\Pictures
So the real answer was always there:

mount -t smbfs //192.168.99.100/Over/Pictures /mnt/share/

It then asked me for a password and I gave an enter (no password).
And it mounted!!

THANK YOU ALL SO MUCH!!!!

I really appreciated all your effort
for trying to help me!!

This is what the world is all about!!


THANK YOU SO MUCH!!!

At the very least there should be a note that this is the default.

Also I didn't see any mention in the voluminous documentation

May I suggest that the CUPS team should take account of
difficulties like this, and adjust the documentation accordingly.

No. Linux uses a "magic" file which tries to guess the type of the file
fromt eh first few lines or bytes in the file. It has guessed that your
file is an "fsav (linux) virux (30839-100)" file. (no idea where your
magic file is /usr/share/magic? ) Ie it has not identified it as a text
file. Look in junk to see what it looks like.

I think you have the field count wrong. Both the fstab lines he uses do have
'noauto' in the options line to stop auto-mounting at boot time. They do have
'auto' in the filesystem-type field so that the mount command will try and
auto-detect the filesystem type (vfat, iso9660,udf,etc) at mount time.

How to get Block File mode on USB port devices?

Posted: 04 May 2004 08:54 PM PDT

Replying to my own posting...
 

Based on some other postings, I tried "modprobe usb-storage". I took several
minutes, but finally did start the SCSI emulation and even figured out that my
camera was a Fuji (correctly).

However, it complained (in /var/log/messages) that it couldn't do resets,
couldn't get the storage size, and couldn't find a partition table. Maybe none
of that matters.

It was listed as "sda", not sdb as in another posting (since I don't have any
other SCSI devices, I guess).

BUT I still can't get "mount" to recognize /dev/sda0 as a "valid block device."
 

Actually, I probably shouldn't have usb-storage loaded or probed for in bootup,
since it takes so long. Just put it in a shell script for rare occasions when
I want to experiment with USB devices.

 

As I found above, loading usb-storage driver starts the SCSI emulation.

Yes, that sounds like a very good idea. I'm sort of 'old school' Un*x, and
also don't entirely trust automatic updates, but I agree, that would have
made things easier when first setting up a system. I've ended up with a
RH9/Fedora/compile from src hybrid, but that's OK, it works. Overall though
I think 2.6x is so different that there were bound to be unexpected things.

I loaded Linux onto them and they just worked. I don't have

linux forgot my password??

Posted: 02 May 2004 09:09 AM PDT

I didn't think to mention that I had selected the boot from floppy
option during the Debian install since I am using XOSL to dual boot
Windows and Debian. So I didn't have a Lilo or Grub prompt.

The console login didn't work either. I was able to use a Knoppix CD
to mount my Linux partitions (OS and swap), then use bash in Knoppix
to use chroot and then passwd root as Bit Twister suggested.

This Linux stuff is humbling. I'm a newbie all over again.

Thanks Bit Twister and Bill Unruh!

Previously, I have recommended reading this:
http://www.tldp.org/HOWTO/Plug-and-Play-HOWTO.html

One key piece of information that this document provides is to advise
users to use "Plug and Play" mode for ISA cards when available. Then,
when setting the BIOS for OS type, select non-plug-and-play for Linux.
This simply means that the motherboard initialization routines will

The "Linux Bootdisk Howto" is an excellent resource- it covers a lot of
ground. It explains everything you need to know and to build a system
yourself. But skipping to the end: Appendix A covers "A.1 Pre-made
Bootdisks." and "A.2 Rescue Packages." Using someone else's loader,
kernel,and root file system could give you a boost to solving your
problem. There is a relatively quick test to see if a pre-built rescue
environment is sufficient to solving your problem. (BTW, it might also
show this environment is overkill and not required at all.) Just try
booting a rescue CD, then "simulating" your script's commands which would
automatically be executed by typing them in yourself. Watch for any
problems when operating under this environment (missing or broken
commands, missing and necessary features, etc.) If your script works as
planned, then save it as rc.local (or another appropriate
startup script.)

You could try Tom's Root/Boot as a very small system:

I infer Peter thinks the O.P. will keep XP and make a dual boot system
with Linux as one of the options. I am not sure how well Linux does at
reading and writing XP's file system (I have not tried it). Probably
depends on the version of Linux he gets.

But even if the files can be read, it is difficult to manage some Windows
files if you do not have programs that can read their ever-changing
undocumented file formats. Some Linux office suites have input filters
that can read some versions of Microsoft Office files (e.g., Word, Excel),
but there are no end of problems trying to manage Access for example.
