/var/VRTSat_lhc directories, before installing VCS One. Before removing
them, ensure that they are not in use by other products.
You can install VCS One on remote systems using either secure shell (ssh) or
remote shell (rsh). You can use remsh (for client installations on HP-UX only).
Symantec recommends using ssh.
The ssh program lets you log on to a remote system and execute commands on
it. It enables encrypted communications and an authentication process between
two untrusted hosts over an insecure network. The ssh program is the preferred
method of remote communication because it is more secure than the rsh suite of
protocols. Symantec recommends configuring a secure shell environment
before installing VCS One and other Veritas products by Symantec. The
following is an example ssh setup procedure.
Before you enable ssh, read the ssh documentation and online manual pages. If
you have questions or issues about your ssh configuration, contact your
operating system support provider. For access to online manuals and other
resources, visit the OpenSSH Web site at:
http://openssh.org
To configure ssh
1
Log on as root on the system where you plan to run the installation.
2
Navigate to the root directory. Enter the following:
cd /
3
Generate a DSA key pair. Enter the following:
ssh-keygen -t dsa
4
At the prompt, press Enter to accept the default location of /.ssh/id_dsa.
Typically, this location is the following:
■
For AIX, HP-UX, and Solaris:
/.ssh/id_dsa
■
For Linux:
/root/.ssh/id_dsa
5
At the passphrase prompt, do not enter one. Press Enter.
6
Press Enter again.
