## 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

In `dsm.opt`, you will have to specify

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;

> `

You do not need to install any shared libraries for these clients; everything is linked statically.
