Configuring ssh, rsh, or remsh before installing
■ At the password prompt, enter the target system’s root password.
■ After you log on to the target system, append the
id_dsa.pub
file to
the authorized key file. Do one of the following:
For AIX, HP-UX, and Solaris, enter the following:
cat /id_dsa.pub. hostname >> /.ssh/authorized_keys
where
hostname
is the name of the system from which you are
copying.
For Linux, enter the following:
cat /id_dsa.pub. hostname >>
/root/.ssh/authorized_keys2
where
hostname
is the name of the system from which you are
copying.
■ After the
id_dsa.pub
public key file is copied to the target system and
added to the
authorized_keys
files, delete it. On the target system,
enter the following:
rm /id_dsa.pub. hostname
■ Log out of the ssh session. Enter the following:
exit
■ When you install from a source system that is also an installation
target, add the local system
id_dsa.pub
key to the local
authorized_keys
file. If the installation source system is not
authenticated, the installation may fail.
Add the local system
id_dsa.pub
key to the local
authorized_keys
file. Do one of the following:
For AIX, HP-UX, and Solaris, enter the following:
cat /.ssh/id_dsa.pub >> /.ssh/authorized_keys
For Linux, enter the following:
cat /.ssh/id_dsa.pub >> /root/.ssh/authorized_keys2
10 Verify that you can connect to the target system. On the source system,
enter the following:
ssh target_system uname -a
The command should execute from the source system to the target system
without the system requesting a passphrase or password.
11 Repeat step 10 on each target system.
Restoring the password requirement between systems
If you configure ssh to enable passwordless communications between systems
during an installation, you can restore the password requirement when the
installation is finished.
