1. Before You Begin
This chapter introduces you to and prepares you for SSH product installation, configuration, startup, and testing. It is for the OpenVMS system manager or technician responsible for product installation and configuration.
Steps to Get SSH Up and Running
To get SSH up and working, you must perform the following steps:
1. Load the license pack.
2. Install the software. See Chapter 2, Installing PSCSSH.
3. Configure the PSCSSH environment. See Chapter 3, Configuring PSCSSH.
4. Configure the PSCSSH SSH V1 server. See Chapter 4, Configuring the Secure Shell (SSH) V1 Server.
5. Configure the PSCSSH SSH V2 server. See Chapter 5, Configuring the Secure Shell (SSH) V2 Server.
6. Configure the PSCSSH client. See Chapter 6, Accessing Remote Systems with the Secure Shell (SSH) Utilities.
Prepare for Installation
PSCSSH installation involves using the VMSINSTAL procedure. Preparing for installation involves:
· Understanding the hardware and software requirements
· Determining if you have sufficient disk space and global pages for the installation
· Determining where to install the software
Hardware Requirements
PSCSSH has no special hardware requirements beyond those stated in the Software Product Description for OpenVMS’s TCP/IP Services.
Software Requirements
PSCSSH supports OpenVMS VAX version 5.5-2 and later; OpenVMS Alpha version 6.2 and higher; OpenVMS Integrity 8.2 and later; and TCP/IP Services version 5.0 and later.
Disk Space and Global Pages
The destination device for your PSCSSH software must have enough disk space so that you can install and run the software. Your system must meet the following approximate parameters:
|
System |
Number of Blocks Needed to Install |
Number of Blocks Needed After Installation |
Free GBLPAGES Needed to Run |
|
VAX |
150,000 |
about 42,000 |
35,000 |
|
Alpha |
250,000 |
about 88,000 |
45,000 |
|
Itanium |
280,000 |
about 135,000 |
45,000 |
|
X86_64 |
280,000 |
about 135,000 |
45,000 |
The runtime values for disk space are slightly higher once you configure and start PSCSSH.
|
Note: Insufficient GBLPAGES can abort the installation and leave your system command tables disconnected. The only way to recover is through a system reboot.

General Requirements
Check at this point that you:
· Have OPER, SYSPRV, or BYPASS privileges
· Can log in to the system manager's account
· Are the only user logged in (recommended)
· Backed up your system disk on a known, good, current, full backup (recommended)
· Need to reinstall PSCSSH after performing a major VMS upgrade
· If PSCSSH is currently running, shut it down using the PSCSSH SHUTDOWN command. This is mandatory.
· Ensure TCP/IP Services is currently running.
Where to Install PSCSSH
Install PSCSSH in a location depending on the following:
· Generally, on your system disk, but you can install PSCSSH anywhere, just answer the question when it appears. This is also where you would keep your "common" files. Node-specific files should always be on your system disk.
· If the machine is in a single platform cluster, on a common disk.
· If the machine is in a mixed platform cluster, once on the Alpha system disk (or disks), once on the Integrity system disk (or disks), and once on the VAX common system disk.
