3. Installing the ADSM client

The SCO binary is supplied as three tar files, or disks. Change to the root directory, set your umask according to your policies, and unpack them from there (as root). In your Directory /tmp, you will find an installation script; execute that.

You will then have to hand-edit /usr/adsm/dsm.sys and /usr/adsm/dsm.opt. In dsm.sys, important lines to specify are:

Servername

The name of the server

TCPServeraddress

The fully qualified host name of the server

NODename

Your own hostname

Server

As before

Followsymbolic

Wether or not to follow symbolic links (not a good idea, in general)

SUbdir

Wether to back up subdirectories (you usually want that)

domain

The file systems to back up

You will then have to create a SCO-compatible /etc/mnttab from your /etc/fstab. You can use the following Perl script, fstab2mnttab, for this.

#!/usr/bin/perl

$mnttab_struct = "a32 a32 I L";

open(MTAB, "/etc/mtab") || die "Cannot open /etc/mtab: $!\n";
open(MNTTAB, ">/etc/mnttab") || die "Cannot open /etc/mnttab: $!\n";

while(<MTAB>) {
    next if /pid/;
    chop;
    /^(\S*)\s(\S*)\s(\S*)\s.*$/;
    $device = $1;
    $mountpt = $2;
    $fstype = $3;
    if($fstype ne "nfs" && $fstype ne "proc") {
        $mnttab_rec =
            pack($mnttab_struct, $device, $mountpt, 0x9d2f, time());
        syswrite(MNTTAB, $mnttab_rec, 72);
        print "Made entry for: $device $mountpt $fstype\n";
    }
}

close(MNTTAB);
exit 0;
