Oracle Fustercluck on Solaris 11

You're trying to install Oracle Cluster? And this thing wants you to install their stuff as "root" user. Except the "root" user cannot go to the other Solaris nodes via SSH, because it is very insecure to Oracle.
In other words, Oracle Cluster is asking you to make your OS insecure first. :-)

Here are steps for you how to fix the issue (saves you a half of a day):

1. Modify /etc/user_attr file.


2. Comment out line CONSOLE=/dev/console in /etc/default/login file.
Why? Read the description there.

3. Allow remote login for root in SSH daemon by editing /etc/ssh/sshd_config file.
PermitRootLogin no

PermitRootLogin yes

4. Restart SSH daemon by issuing the following command:
# svcadm restart /network/ssh

5. Set password for root:
# passwd root

6. Generate SSH keys:
# ssh-keygen -t rsa

Phew! Now you can put your public SSH keys elsewhere and enjoy Snorcle Fustercluck Oracle Cluster installation (as an example). :-)
