I am using the bin-rpms from SLES 10 SP2...

Which heartbeat-rpm should contain the snmp-stuff?

How can I check wether HB has been compiled that way?

Why is there no man-page about this topic?

Why rw? ro should be enough...
You can do some nasty things with snmp-write-commands...

According to "man snmpd.conf" it should be "master agentx"?

How can I determine wether this works?

LinuxHA: Unknown Object Identifier (Sub-id not found: iso -> LinuxHA)

I guess I have to put the mib for Heartbeat somewhere the snmp-client
can find it.

Version 2c should work - I see the other mibs there.

BTW: Does the AgentX open a security-hole? How can I restrict
registering to the local host?
