2.3.1 Setup of SSH and NFS
Before we can start the mass deployment, a secure and convenient
authentication channel must be set up to allow us to issue commands with proper
privileges to the remote machines.
Installing SSH on managed machines
For AIX platforms, OpenSSH and its prerequisites might not be installed by
default. Since in our case,
ssh
is required as the remote shell tool, OpenSSH has
to be installed and configured. For details, visit the AIX Information Center on the
IBM Web site and select the appropriate version of the AIX:
After OpenSSH has been installed, we can see the file sets, similar to those in
Example 2-9.
Example 2-9 NFS file sets on AIX
openssh.base.client 4.3.0.5301 COMMITTED Open Secure Shell Commands
openssh.base.server 4.3.0.5301 COMMITTED Open Secure Shell Server
openssh.license 4.3.0.5301 COMMITTED Open Secure Shell License
openssh.man.en_US 4.3.0.5301 COMMITTED Open Secure Shell
openssh.msg.en_US 4.3.0.5301 COMMITTED Open Secure Shell Messages -
openssh.base.client 4.3.0.5301 COMMITTED Open Secure Shell Commands
openssh.base.server 4.3.0.5301 COMMITTED Open Secure Shell Server
After the
ssh
service is available on your UNIX or Linux system, you can use the
ssh
client to connect to it. The basic
ssh
command is shown below:
ssh [user]@
During the first
ssh
connection to the machine, you will be prompted to accept a
RSA authentication key. Type yes and input the user’s password. See
Example 2-10.
Note: For Linux platforms, OpenSSH is generally installed by default. Use the
command
rpm
to check for availability of OpenSSH on your Linux:
rpm -qa|grep -i ssh
Then ensure that the
ssh
service is up and running. For example, on SUSE
Linux or Red Hat Linux, you can issue the
service
command to obtain a
status report from the operating system:
service sshd status
