## 15.6 Installing a License Server for an SGI Workstation

### Installing a License Server for SGI Workstation from Tape

Note: The block size of the tape device must be set to 512 bytes. Use the following command to determine the current block size:

    mt -t <device> blksize

<device> is the appropriate tape device for the operating system from which you run installdx. Example IRIX tape devices are:

    /dev/rmt/tps0d4ns, /dev/rmt/tps0d5ns, ...

On IRIX be sure to use the no-swap tape drives which have the characters "ns" in the device name.

Use the following command to set the correct block size if necessary:

    mt -t <device> setblksz 512

Tape distributions of Data Explorer contain three tar format files. The first contains two install scripts (`installdx`, `install_lsk`) and a PostScript file documenting the Network Computing System (`ncs_ps.Z`). The second contains the Data Explorer installation tree which contains Data Explorer for all supported architectures. The third file contains NetLS license server installation kits for each supported architecture.

To install the license server, log in as root, insert the tape in the drive, and type:

    cd /tmp
    tar xvf <device> install_lsk
    ./install_lsk

<device> is the appropriate tape device for the operating system from which you run `install_lsk`. Example IRIX tape devices are:

    /dev/rmt/tps0d4ns, /dev/rmt/tps0d5ns, ...

Please follow the instructions presented by `install_lsk` carefully. In particular, when asked to give the name of the tape device, be sure to give the name of the non-autorewinding tape drive, examples of which are provided by the script. Also, if at anytime during the tape installation you are asked to mount the next tape, just press the <ENTER> key to have the installation continue normally.

### Installing a License Server for SGI Workstation from CD-ROM

CD-ROM distributions of Data Explorer contain a mountable file system that includes the installation scripts (installdx.sh for Data Explorer and install_lsk.sh for the NetLS license server software), the software itself (in tar format) and documentation.

To install the license server, log in as root, insert the distribution media in the drive, and type:

    mkdir /cdrom

Mount the CD on /cdrom. Mount the disk by entering the following command:

    mount -r -t iso9660 <CD-ROM-Device> /cdrom

where <CD-ROM-device> is the actual name of the CD-ROM drive on your system. A typical name is `/dev/scsi/sc0d0l0`.

Type:

    cd /cdrom
    ./install_lsk.sh
