Installing The Ssh Key; Mysql-Server Package - Red Hat NETWORK SATELLITE 5.1.1 Reference Manual

Chapter 7. Monitoring

7.2.4. Installing the SSH key

Whether you use rhnmd or sshd, you must install the Red Hat Network Monitoring Daemon public
SSH key on the systems to be monitored to complete the secure connection. To install it:
1. Navigate to the Monitoring
name of the RHN Server that will monitor the client system. The SSH id_dsa.pub key is visible on
the resulting page.
2. Copy the character string (beginning with ssh-dss and ending with the hostname of the RHN
Server).
3. On the command line of the system to be monitored, switch to the user aligned with the daemon.
This is accomplished for rhnmd with the command:
su - nocpulse
4. Paste the key character string into the ~/.ssh/authorized_keys file for the daemon's user. For
rhnmd, this is /opt/nocpulse/.ssh/authorized_keys.
If config management is enabled on the systems to be monitored, you may deploy this file
across systems using a config channel. Refer to
Management"
for details.
Note
If valid entries already exist in authorized_keys, add the daemon key to
the file rather than replacing the existing key. To do so, save the copied text to
id_dsa.pub in the same .ssh/ directory and then run the following command:
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys.
5. Finally, ensure the .ssh/ directory and authorized_keys file have the appropriate permissions
set. This can be done as the daemon's user with the following commands:
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
Once the key is in place and accessible, all probes that require it should allow ssh connections
between the Monitoring infrastructure and the monitored system. You may then schedule probes
requiring the monitoring daemon to run against the newly configured systems.

7.3. mysql-server package

If your RHN Satellite Server will serve Monitoring-entitled client systems against which you wish to run
MySQL probes, you must configure the mysql-server package on the RHN Satellite Server. Refer
Appendix C, Probes
to
Subscribe the Satellite to the Red Hat Enterprise Linux AS Extras channel and install the mysql-
server package either through the RHN website or via up2date.
