IDE Drives re-ordered after Kernel upgrade?

It does mean the IDE code has been poked around. Since 2.6 is coming into
major use, you may just want to leapfrog the issues of playing with 2.4.
Alternatively, what about upgrading 4 revisions at a time, instead of 11?
And try a 2.4.23 kernel, which I believe was pretty good?

can't install RedHat 9 / my WD disk is not recognized

Recent releases of Linux can resize NTFS. It's much safer than attempting to
write files inside NTFS, for a stack of technical reasons. The commonly used
tool for this is "parted", and I just stood amazed as a SuSE 9.2 intalltion
DVD did it automatically to a Windows XP Home box I thought would first have
to be scrubbed.

can not access cd-rom

Posted: 14 Feb 2005 01:52 PM PST

OK, figured out, but still have question.

I add ide=nodma to the grub init script, now the CD-ROM works great!

My question: from the name of this configuration, it seems I turns off
DMA on IDE bus, then isn't that data access to both CD-ROM and harddisc
will be slowed down? Is there any way I can only turn off DMA to
CD-ROM, but not other devices?

My guess is my Samsung CD drive is of old type, it is not working very
well with the 2.4.22 kernel. But this kernle is the one I need to use.

Google returns a page saying same problem as mine, that person says
RedHat 7.3 works fine with his/her CD-drive. I wornder what kernel
version of 7.3 is? I am using Fedora core - 1 and its kernel version is
2.4.22.

I am wondering if I should uninstall my current Fedora and install
RedHat 7.3.

Sorry for my curiosity, I know it does not matter, but just want to
know...

" password entered at the screen is encrypted and compared to the
encrypted
password stored in the system."

-- when you say "stored in the system", it must be some file on the
harddisck, right? Actually I my system is RedHat and see a file
/etc/shadow, as root I open the file, and I see something looks like
root encrypted password, they are ascII characters, but not the one I
input on the screen, anyway is it the encrypted password for root?

Thanks.

Booting TWO win partition with DIRECTLY with GRUB

Posted: 14 Feb 2005 02:09 AM PST

I found out that the XP registry holds information about mounted disks
(it suffices that the XP sees these disks once) and then even if you
hide them with grub, XP still knows about them.

What I did was erase the mounted disks entries from the registry.

And once again Peter spends his day yanking the chains of newbies and
leaving out the important bits, just to pretend that his opinion is somehow
useful.

/dev/cdrom is often, not always, set up as a symbolic link to the "real" CD
device. Different software has different conventions about this, and various
things can change what your CD device actually shows up as. For example,
older versions of the "cdrecord" software cannot handle CD devices with
write capability as IDE devices, so older versions of cdrecord and the 2.4
kernel require you to load the ide-scsi module to do any CD writing. This
can confuse the heck out of various auto-probing software, and when you
later load the modules or decide not to load them, you wind up with a link
from /dev/scd0 to /dev/cdrom, or from /dev/hdd to /dev/cdrom, and it may not
do what you expect.

In general, don't use /dev/cdrom because of exactly this sort of confusion.
The idea of using symlinks to give devices easily understand names is
common, but fragile, Instead use the IDE device directly (which you can
check for by looking in /proc/ide and checking which /proc/ide/*/media file
has "cdrom" in it), or use the SCSI device directly (usually /dev/scd0 if
your CD drive is showing up as SCSI).

Most Linux installations try to do this for you, but they're not consistent
or reliable about it. RedHat, for example, tries to auto-detect the CD drive
and set the symlink /dev/cdrom to something usable. SuSE tries to
auto-detect such devices and access them as mountable locations /media/cdrom
but shows the same device as /media/cdrecorder, for example.

Never put your bare bones OS on software RAID, because when it gets screwed
up for whatever reason, it can be exceptionally difficult to repair. SuSE is
especailly bad for this, since their "rescue" setups seem to lack most of
the important drivers and tools that the "installation" setups provide form
the same installation media.

First, use "yum" to do a full update of *everything*. Yum is available for
RedHat 9 from the www.fedoralegacy.org website and works quite well for
working out all the dependencies.

Second, consider updating from RedHat 9, which has been unsupported and
deprecated for at least a year now.

Third, what are you trying to build in PHP and Apache that is not in the
standard or updated releases for RedHat 9?

Fedora Core 2 wont detect modem.

Posted: 12 Feb 2005 07:05 PM PST

It is a winmodem more than likely.
If the following doesnt work buy a "real" hardware based external modem.

http://www.linuxvoodoo.com/resources/howtos/dell_2650_modem/

Most Dell Inspiron 2650 laptops come with the Actiontec 560RD based winmodem
which requires the drivers available below. This is one of those cases
where you do actually need a seperate download. Installation is fairly
straightforward as the driver's installation script is pretty smart at
configuring your modem.

Requirements

* A Dell Inspiron 2650 with the Actiontec modem (or any other system
with a supported HSF modem)
* Linux drivers for Conexant (formerly Rockwell) Softmodem HSF modem
family.
* At least a 2.4 (stable) kernel (source installed and previously
compiled.

Installation
Start with the download (see resources below). The following instructions
are from the INSTALL file included with the tar.gz package. Since not
everyone is using a Red Hat based system, I'll use instructions for the
source package.

1. Extract the package with "tar -xzf hsflinmodem-{version}.tar.gz"
2. Change to the package directory with "cd hsflinmodem-{version}"
3. Run "make install" from the top of the package directory.
4. Run "hsfconfig" to complete the installation and configure your modem.
5. Follow the on-screen instructions - usually selecting the default for
this modem works fine (if you are in the USA).

Installation Notes
Debian users might need to change the KERNELSRC definition in
modules/common.mak before running the make install command. An example is
included on how to change that KERNELSRC line on the top of the
modules/common.make file included in the source tree of the drivers.

Red Hat and similar users can generate RPMS from the tar package using "rpm
-ta hsflinmodem-{version}.tar.gz".

Post-installation
At this point the modem is installed and configured and you can access it
through /dev/ttySHSF0 or /dev/cuaHSF0 (call-out device). Additionally, you
can use it via the symbolic link /dev/modem (equivalent to ttySHSF0) which
is usually automatically created during the installation process.

User access
To allow non-root users to access this device you can create a new group
with for example "groupadd modem" and change the permissions on
the /dev/ttySHSF0 device to modem with "chown root.modem /dev/ttySHSF0".
Simply add the users to the /etc/group file under the modem group so it
looks like this: modem:x:1004:user1,user2,user3,freddy. Note that the group
id (1004) will vary from system to system.

Double check the permissions on the device nodes with "ls -l /dev/ttySHSF0"
to ensure that they are adequate for your system. Alternatively, you can
set the same permissions used above to the /dev/modem symbolic link for
easier access to the modem.

Using the modem
You can now use any dialup tool you wish, such as wvdial, the Red Hat dialup
tool, KPPP etc. These are standard tools on most distributions. When asked
to specifiy the port or modem device to use simple specify /dev/modem
or /dev/ttySHSF0 which ever is convenient.

Making changes later
The "hsfconfig" command can be used to change certain modem configuration
options or recompile (generic packages only) the kernel modules after
installation. Run "hsfconfig --help" for usage information.

Questions?
Use our support resources (forums, live chat, e-mail forms etc).

Resources

* http://www.mbsi.ca/cnxtlindrv
* The README and INSTALL files included in the Conexant HSF package
* Current Conexant HSF package driver download
* Supported modem/controller list: HSFi, HSF, Intel MC97 Controller
(ICH), VIA MC97 Controller, ALI MC97 Controller, Basic2 / SmartDAA, Athens
(Yukon) (Complete list)

FEDORA CORE2- eth0 goes "inactive" after reboot-HELP!

Posted: 12 Feb 2005 08:39 AM PST

The system is using static IPs not DHCP

I originally was using FC3 but uninstalled it because they removed
support for the mega raid driver. So I went back to FC2. I had this
same problem in FC3.

This is running on brand new hardware.

Redhat vs Slackware?

This is basically true. Although Slackware can use rpm to some degree.
And nothing is stopping you from using tar'ed packages on RH.

 

I suppose this is true. RH does seem to have more gui config tools.

 

I think you got this backwards.
To quote from Slackware documentation : "Slackware uses the BSD-style
layout for its initialization files. Each task or runlevel is given its
own rc file. This provides an organized structure that is easy to
maintain.
There are several categories of initialization files. These are system
startup, runlevels, network initilization, and System V compatibility. As
per tradition, we'll lump everything else into an "other" category."

Firewall for Linux

Linux has a built-in, kernel level firewall that can be configured using
iptables. The defaut settings are usually pretty restricitve, so unless
you have specific requirements (running various servers, etc.) you
probably don't have to do much with it. You can see what rules are being
used by running "iptables -L" at a command prompt.

Pop-ups, ads, and cookies are application level annoyances, and need to
be dealt with at that level. FireFox and Mozilla both have excellent
pop-up and cookie control built in, and the AdBlock extension can be
installed to block ads as well.

Hm, this might be the problem. My regular Debian based 2.4 setup without

The 2.6.9 Fedoraalike gets only the Rev: 1_27 field while having both

Yes, that might be the case. I immediately found and tried modprobe.conf

but blacklisting the module(s) didn't help either. OK. Going to check

How to write on a NTFS partition

Posted: 11 Feb 2005 10:06 AM PST


"Michael Heiming" <michael+heiming.de> wrote in message
news:heiming.de... 

OK, good point. Or you'd need to add an external drive. Do you have the
space to install wienie partitions?
 

This can actually work, as long as you haven't over-partitioned and stripped
down the available space for /home due to allocating space for /usr/src,
/usr/local/, /var/tmp, /var/tmp, /var/spool, /etc., etc., etc.. In the last
5 years, I've done this *once*, with someone who really liked having really
old (for speed) distros along with really new (for performance) distros.
There are some potential issues.

#1. Not all distros create compatible file systems, even the same type of
file system. The 7.x RedHat release, for example, used a mkfs that made the
ext2 partitions unreadable to 6.x. I ran headlong into that one: you had to
use the mkfs binary from RedHat 6.x

#2: You probably want to keep the entirety of both file systems available to
the other OS installations. Let's say that "/" from one OS becomes "/diska/"
when mounted on the other, and "/" from the other becomes "/diskb" when
mounted on the first. If you leave the /home still as part of the first OS
and mounted there, it can be accessed by a symlink to /home -> /diska/home.
Workable, but graceless.

#3: HOWEVER! Different OS's often have rather different ideas about user
configuration files, and therein lies the rub of maintaining the identical
user account across multiple OS's. The associated .X configuration files,
..gnome, .mozilla, etc. can and do interfere with each other. I've seen
systems destabilize wildly because the .cshrc written for one system caused
utter chaos when implemented on the other. (Admittedly, it was a terrible
..cshrc, but still, it wasted quite a lot of my time getting the person to
let me fix it for them.) So that's actually a reason *against* sharing
/home's between OS's, even on the same laptop.

In such a situation, I can certainly see using a shared partition. But I
wouldn't make it /home.

Linux's HPFS Support

Posted: 11 Feb 2005 06:08 AM PST

Alex Taylor wrote: 

I agree it's not hard and it is a fairly simple concept, but that wasn't
really what I was getting at. I've been compiling Linux kernels for the
past seven years or so. As a systems manager for many years before that
I also had to regularly squeeze every bit of performance I could from HP
minicomputers and so on, quarter ton things with architectures that made
anything smaller seem like toys to me - OS/2 and Linux made me change my
view there! So as an ex tech-head, I still have a tweaking urge for any
PC operating system operating that's worth it.

In recent years though, I've been on the other side of the fence, with a
business as well as technology focus. I've got a keen interest in doing
my little bit, as many others around the world are also, to make Linux a
serious desktop alternative for government use in particular. I'd argue
that a "serious Linux user" in this wider context is not about compiling
kernels, it's about business users, open standards, interoperability and
being able to get the job done better with a lower TCO and good support.

So on my home setup, I prefer to get things up and running smoothly so I
can start being productive, the tweaking should come later. That for me
means having at least one partition that any modern Linux flavour should
be able to see out of the box, so that I have instant access to drivers
and configuration notes I may need straight away. FAT32 seems to be the
pragmatic choice for that these days. Another consideration is that the
modern Linux distributions are becoming more sophisticated in the way of
scripting and configuration. Poking around in Xandros reveals some
very fancy stuff that needs some study first. I did a quick kernel
recompile the other night with no errors but quite a few module warnings
which I'd prefer to look closely at later rather than installation time.
Now that I have everything operational, I'll probably revisit Xandros
& HPFS when I get some spare time.
