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:
The name of the server
The fully qualified host name of the server
Your own hostname
dsm.opt, you will have to specify
As before
Wether or not to follow symbolic links (not a good idea, in general)
Wether to back up subdirectories (you usually want that)
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;
