Agent Unable To nslookup The CMS Hostname
Symptom The command mxagentconfig -a
cms_name
-p
password
fails with:
Unknown host name: ‘cms_name’
Verification Use nslookup
cms_name
to test the network name resolution on the managed node.
Fix Setup network name resolution properly on the managed node by adding CMS
information to the managed node’s /etc/hosts file. See “Problems With resolv.conf,
hosts, nsswitch” on page 19 for additional information.
Authentication Failures Due To Time Synchronization
Or Communication Time Limits
The CMS and managed nodes must be time-synchronized to prevent authentication
failures. The communication time limit is 20 minutes, and exceeding this limit causes
authentication failures.
Symptom Executing a tool on a managed node results in the error:
Authentication failure: The CMS and managed node time clocks may not
be synchronized, or a communication time limit may have been
exceeded.
Fix Use the command xntpd(1m) to configure the time synchronization.
CMS Unable To nslookup Node Hostname
Symptom The command mxnode -a
node_name
or mxnode -r
node_name
fails with:
Unknown host: ‘node_name’ Node ignored.
Verification Use nslookup
node_name
to test the network name resolution on the CMS.
Fix Setup network name resolution properly on the CMS. See “Problems With resolv.conf,
hosts, nsswitch” on page 19 for additional information.
