2. Identify the user to be associated with the daemon. This can be any user available on the
system, as long as the required SSH key can be put in the user's
~/.ssh/authorized_keys
file.
3. Identify the port used by the daemon, as identified in its
/etc/ssh/sshd_config
configuration file. The default is port 22.
4. Install the SSH public key on all client systems to be monitored, as described in Section 2.4,
“Installing the SSH key” .
5. Start the
sshd
on all client systems using the command:
service sshd start
6. When adding probes requiring the daemon, insert the values derived from steps 2 and 3 in
the RHNMD User and RHNMD Port fields.
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 Satellite Tools # Satellite Configuration # Scout Config Push page on the
Satellite interface and click the 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 Section 7.1, “Preparing Systems for Config
Management” for details.
