netmon -h not working with NNM 6.20? 1

[Eric77]

NNM Release B 06.20 with NNM_00932 (consolidated Patch 3) and NNM_00975 patches is being tested with a network that includes a Unisys server running the MCP operating system. The TCP/IP stack on that system is reporting probes on port 280 from the system running HP OpenView.

(1) As far as we can tell, these probes weren't seen on this port before. Was this a change made in a recent HP OpenView NNM patch?

(2) More importantly, the operator tried to disable this probing by entering netmon -H 0 (zero), following a suggestion in the HP OpenView 5.0 documentation. (We're aware that this documentation is for an older level. The reference is

http://support.openview.hp.com/pdf/dev_ov_netmon97.pdf

near the end.) Even though the syntax appears to be correct, all he gets back is the "help" list of options as though he had entered an incorrect option... yet the -H option is listed. Entering a non-zero value (netmon -H 1) and trying it without the space (netmon -H0) had the same effect. Entering netmon with no parameters returned a status saying it was running. Either (a) the syntax changed, (b) this can't be entered while netmon is running, or (c) netmon is no longer used to suppress the port 280 probing with HP OV 6.x. When/how can the HTTP probing be disabled?

Thanks in advance!

On the NT/2k version of Openview (6.2), the http manageability checking, http capability checking (port 280), and RDMI capability checking (port 37907) is performed by ovcapsd. We shut this off by unregistering ovcapsd (ovdelobj ovcapsd.lrf), therefore disabling this process.

Thank, William! We also found two helpful pages on the HP Web site. In case anyone else needs this information:

Look at the "Jeff ware" response about halfway down. That in turn points to this HP Technical Document for more details:
