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.
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 SSH for OpenVMS.
3. Configure the SSH for OpenVMS environment. See Chapter 3, Configuring SSH for OpenVMS.
4. Configure the SSH for OpenVMS SSH V1 server. See Chapter 4, Configuring the Secure Shell (SSH) V1 Server.
5. Configure the SSH for OpenVMS SSH V2 server. See Chapter 5, Configuring the Secure Shell (SSH) V2 Server.
6. Configure the SSH for OpenVMS client. See Chapter 6, Accessing Remote Systems with the Secure Shell (SSH) Utilities.
SSH for OpenVMS 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
SSH for OpenVMS has no special hardware requirements beyond those stated in the Software Product Description for HP’s TCP/IP Services.
SSH for OpenVMS supports OpenVMS VAX version 5.5-2 and later; OpenVMS Alpha version 6.2 and higher; OpenVMS Itanium 8.2 and later; and TCP/IP Services version 5.0 and later.
The destination device for your SSH for OpenVMS 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 |
I64 |
280,000 |
about 135,000 |
45,000 |
The runtime values for disk space are slightly higher once you configure and start SSH for OpenVMS.
Note: Insufficient GBLPAGES can abort the installation and leave your system command tables disconnected. The only way to recover is through a system reboot.

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 SSH for OpenVMS after performing a major VMS upgrade
· If SSH for OpenVMS is currently running, shut it down using the SSHCTRL SHUTDOWN command. This is mandatory.
· Ensure TCP/IP Services (or UCX) is currently running.
Install SSH for OpenVMS in a location depending on the following:
· Generally, on your system disk, but you can install SSH for OpenVMS 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 Itanium system disk (or disks), and once on the VAX common system disk.
The SSH for OpenVMS Release Notes provide important information on the current release. If you are installing from CD-ROM, you can access the Release Notes and the full SSH for OpenVMS documentation as PDF files. They are in the [DOCUMENTATION] directory. The Release Notes for this product are in the file SSH024.RELEASE_NOTES.
The Release Notes, along with the rest of the documentation set for this product, are always available for viewing and download on the Process Software website at https://www.process.com/ under the Support area.
