2    Installing the Secure Shell Software

The way in which you install the Secure Shell software depends on the version of Tru64 UNIX that you are running:

This chapter describes:

2.1    Downloading the Secure Shell Software

The Secure Shell software is in a compressed tar file called sshv32.tar.gz that you must download. The tar file contains:

To download the Secure Shell software:

  1. Create a directory called /usr/share/doclib/ssh and change to that directory.

  2. Using a Web browser, go to:

    http://www.tru64unix.compaq.com/unix/security-internet.html
    

  3. Select to download the Secure Shell software kit and follow the instructions on the screen.

2.2    Upgrading the Secure Shell Software

To upgrade to the Secure Shell Version 3.2 software, you must first remove the installed Secure Shell software, then install the Secure Shell Version 3.2 software.

To remove the Secure Shell Version 1.0 software:

# /usr/sbin/setld -d SSHBASE100 SSHDOC100 

To remove the Secure Shell Version 1.1 software:

# /usr/sbin/setld -d SSHBASE110 SSHDOC110

2.3    Installing the Secure Shell Software

Installing the Secure Shell software:

To install the Secure Shell software:

  1. Change to the directory where you downloaded the Secure Shell software.

  2. Uncompress and extract the contents of the downloaded Secure Shell tar file:

    # gunzip -c sshv32.tar.gz | tar -xvf -

  3. Uncompress and extract the Secure Shell subsets:

    # gunzip -c ssh_v32_1866.tar.gz | tar -xvf -

  4. Install the Secure Shell subsets:

    # setld -l ./kit SSHBASE320 SSHDOC320

2.4    Installing and Viewing the Secure Shell Documentation

To install the Secure Shell documentation:

  1. Change to the directory where you downloaded the Secure Shell software.

  2. Uncompress and extract the contents of the Secure Shell documentation tar file:

    # gunzip -c ssh_v32_docs.tar.gz | tar -xvf -

To view the documentation, open the /usr/share/doclib/ssh/DOCS/HTML/LIBRARY.HTM file in a Web browser.

2.5    Starting the Server Software

After you install the Secure Shell software, you must start the sshd2 daemon to start the server. When the sshd2 daemon starts, it uses the values assigned to keywords in the /etc/ssh2/sshd2_config file to configure how the server responds to clients.

Review the keywords in the sshd2_config file before starting the sshd2 daemon. See Section 3.1 and sshd2_config(4) for more information about the sshd2_config file.

To start the sshd2 daemon:

# /sbin/init.d/sshd start

In a TruCluster Server environment, you must start the sshd2 daemon on each cluster member on which you want the sshd2 daemon to run.

The sshd2 daemon will automatically start when the system boots.

2.6    Removing the Secure Shell Software

To remove the Secure Shell software:

# setld -d SSHBASE320 SSHDOC320

The Secure Shell directories and software subsets are left in place.

2.7    Removing the Secure Shell Documentation

To remove the Secure Shell documentation:

# rm -rf /usr/share/doclib/ssh/DOCS
