HP UX Matrix Operating EnvIronment manual # cd /.ssh /* rootuserhomedirectory/.ssh

Page 45

If the configuration is still not working, you may see an error message:

Ssh Operation failed for node:managed_node.

The connection could not be established.

Reason:Failed to read remote identification

In conjunction with this, you may also notice that running mxagentconfig and selecting Configure→Configure or Repair Agents fail on the target managed node.

To reconfigure SSH on the managed node, do the following steps:

1.Log on the managed node as user root.

2.# cd /.ssh /* <root_user_home_directory>/.ssh */

3.

# rm * /* Erase all possible

corrupted contents */

4.

# ssh-keygen -b

2048

-t

rsa /* Generate root ssh key */

5.

# ps -elffgrep

sshd

/*

Find

the sshd PID */

6.# kill -1 <pid> /* Re-start sshd */

7.# mxagentconfig -a -n managed_node

8.# /opt/amgr/bin/agent_config -start

Once this action is taken, check that Application Discovery is receiving messages from the host. (See #8 in this section.)

7.Check that the WBEM connection is working correctly on the managed node.

To check the status of the WBEM connection, do the following in Application Discovery user interface:

a.Click the AD Agents tab.

b.Look for the WBEM Stat column in the 'Hosts/Agents' table. If the status message for WBEM is not 'OK', do the following:

Check that HP SIM CMS has an authorized logon with the managed system. See Appendix E (page 67) to complete this authorization.

Alternatively, you can configure the managed system's WBEM authorization to trust

the CMS to perform a remote "root" WBEM user logon. Do this by clicking Configure →Configure or Repair Agents. Make sure to mark the box for 'Configure WBEM client certificate authentication' before you run the tool.

Once this action is taken, check that Application Discovery is receiving messages from the host. (See #8 in this section.)

8.Check that Application Discovery is receiving messages from the host.

a.Click the following tabs in Application Discovery: Admin/Config, then AD Agents.

b.Find the column headings providing message data on the far right of the data table on this screen. Check that the cells have data and that the time stamp is within the period set by the Global Host/Process Interval selector on that screen.
