agent++3.3 SnmpRequest::trap

[Guy.HINDELL____opentrade.co.uk]

Hi Jochen

Many thanks for that - it works now. In fact I don't think it is possible to
create the CTarget object direct from a char * - the constructor prototype
can take a reference to an Address object, but not a UdpAddress, so
CTarget("targethost:162") won't work, but
CTarget(UdpAddress("targethost:162")) will. Whatever.

I can see a couple of curious pieces of behaviour with traps sent using
Agent++. I am using the UCD 'snmptrapd' program as a receiver, and it shows
an 'Uptime' as part of the trap (both version1 and version2c) which is way
higher than the actual system uptime (a couple of months), or the uptime of
the agent (a few seconds). I see this when sending traps from both my
Solaris and Linux agents.

The NT extension agent behaves slightly differently - it produces very high
uptimes which appear to be several orders of magnitude greater than the
uptime of the agent and rapidly increase between traps. I wonder if a time
value is being passed somewhere in milliseconds rather than seconds?

Thanks again for your help

guy

		you can do this with the following commands:

			UdpAddress address("targethost:162");
			CTarget target(address);
			target.set_version(version1 or 2c);
			target.set_readcommunity("public");
			SnmpRequest::trap(target, vbs, vb_size, ...)

		It should be possible to construct the target with a char*.

		Best regards,
