Newbie Questions - RedHat 4.0 Linux

Post by Lakshmi Narayana » Wed, 08 Jan 1997 04:00:00



I have installed RedHat 4.0 on my 2nd IDE drive /dev/hdb.
        I made a linux boot floppy that gives me the option to boot
        linux or dos. BTW I have w3.1 on primary IDE drive
        Eeverything boots fine...

        H/w Spec - Dell XPS90 (pentium -90mhz), 24 MB,
                  2 IDE drives(/dev/hda (W3.1), /dev/hdb (linux))
                  Number Nine GXPro/64 Video card, NEC scsi 4x cdrom drive

        My questions are:
        Q1 How do I make a copy of my linux boot diskette?
            rawwrite?? How???

        Q2. How do I mount my CDROM from linux?
                mount /dev/s???
            I have a adaptec SCSI 4x CDROM running under teh 1510 controller
             (scsi-id=5 LUN=0 - this is what DOS tells me when it boots)
            I installed linux from the RedHat CD - So it is accessible

        Q3. Also when linux boots, it waits for about 60-70 secs when starting
             up sendmail. what is it doing?
             My machine is still an "island" - No network card etc.

For a bitwise copy "dd" is the best tool ("man dd" for further details).
If you have two floppies, just do a "dd if=/dev/fd0 of=/dev/fd1" to make a
copy of the disk in the first drive to a disk on the second drive.
If you have only one floppy, you will have to store the content somewhere:
        dd if=/dev/fd0 of=/tmp/floppycontent
        dd if=/tmp/floppycontent of=/dev/fd0

Remeber, you will have to be root to access the raw floppy device.

Don't be too sure about that. Sometimes the setup process installes a
different kernel than the one, that was used for setup.

Check the boot messages for some message about your controller and the
detected SCSI devices.
- If they are missing, your kernel doesn't support SCSI or your controller
or SCSI-CDROM
- Otherwise the message will tell you, which device is used for your CDROM
(most probably /dev/scda)

Make sure, your kernel supports the iso6990 filesystem (look in "/proc")

Then do a "mount -t iso6990 /dev/scda
/<wherever-you-want-to-mount-that-drive>"

Maybe sendmail tries to receive/send mail and waits 60 seconds until it
gets a timeout because it can't find a network connection.

The following solution worked for me under Redhat 4.0.

As root, edit your /etc/hosts file so that it becomes (after editing):

        127.0.0.1       localhost       myhost myhost.mydomain
        0.0.0.0         myhost

As root,
        stop sendmail by:

        /etc/rc.d/init.d/sendmail.init stop

Then restart sendmail by:

        /etc/rc.d/init.d/sendmail.init start

Alternatively, if you don't want sendmail, you can get rid of sendmail
daemon using the control-panel's runlevel editor.

 
 
 

1. Newbie - Redhat 4.0 install questions.

Hi Linux Experts:

   This is my first experience with Linux.  

   I've given up trying to put Linux (Redhat 4.0) on my old 486.  

   When attempting to install it on my P6 I had the following problems:

   My Matrox Millennium 4 Meg board can't be set to 24 Bit color, and
1280x1024.  It has to be set at the next lower resolution or color
depth.  If my math is correct, 4 Megs should support this resolution
and color depth.  I believe Redhat is using Metro Link's drivers, I
have had good experience with Metro Link in the distant past, so I
expect them to provide good drivers to any card they support.  I
realize Matrox's demand for NDAs have prevented proper drivers being
part of xfree86 until the latest release.  Are my assumptions correct?
NT and WIN 95 seem to work fine at this resolution and color depth

   My Intel EtherExpress 100B Pro isn't recognized.  Is there a Linux
driver for it?  

   I put Lilo on my Linux partition rather than the master boot.  I'm
getting a message kind of like "No OS found" when I set my Linux
partition active.  I'm not familiar with the implications of changing
the master boot, NT and WIN 95 partitions seem to boot OK, I would
rather just leave the master boot alone.  

   Anyway, I would appreciate any input.  

                                                               Thanks
                                                               Larry
