Software Installation

Login to an unused tty on a Linux machine. Run the "ps" program with the "ax" command line option by typing

$ ps ax<Enter>

Insert the distribution diskette into a floppy drive. If you have more than one floppy disk drive determine the name of the floppy drive. In the examples that follow /dev/fd0 is used.

The files have been placed on the floppy disk using the "tar" and "gzip" utilities. If you wish to list the files on the disk before you install them, type:

# tar -ztf /fd0/sccopy.tar <Enter>

To install the software, first login as a superuser. Make sure the current working directory is "/" by typing:

# pwd <Enter>

# cd / <Enter>

Run the tar utility:

# tar -zxvf /fd0/sccopy.tar<Enter>

The programs are placed in /usr/bin and the on-line manual is placed in /usr/doc/secondcopy-0.12. Check the success of the installation by looking at /usr/bin/s*. You should see secondcopy programs listed when you enter:

# ls /usr/bin/s* <Enter>

Remove the distribution diskette from the floppy drive and put it in a safe place. Fill in the information in the section of this manual titled "Site Notes".

Now, read, sign, and return the accompanying warranty and registration sheet.

Next you must build into the kernel the correct device driver for your SCSI controller. The appropriate documentation is found on your distribution media or web site.

Finally, make a floppy to be used for recovery from a disastrous disk problem.

Creating an Emergency Boot Diskette

1. First, copy a Linux Operating System Boot Disk with the following steps.

a. Insert the Linux boot floppy into the floppy drive. In this example we assume the drive is called /dev/fd0.

b. Copy the entire disk to a file with:

# dd if=/dev/fd0H1440 of=/tmp/bootdisk <Enter>

c. Remove the Linux boot disk and insert a new disk in the floppy drive. Enter the following commands to format and copy the file back to the disk.

# fdformat /dev/fd0H1440 <Enter>

# dd if=/tmp/bootdisk of=/dev/fd0H1440 <Enter>

2. Mount the disk and copy the following programs to the disk:

# mount /dev/fd0 /fd0 <Enter>

# cp /bin/ls /fd0/bin <Enter>

# cp /bin/fsck /fd0/bin <Enter>

# cp /usr/bin/secondcopy/secondcopy /fd0/bin <Enter>

# cp /usr/bin/secondcopy/scdir /fd0/bin <Enter>

# cp /usr/bin/secondcopy/sc /fd0/bin <Enter>

3. Unmount the floppy and store it in a safe place.

# umount /dev/fd0 <Enter>
