Re: snmpinform and not in time window

Hi Folks,

1. snmptrapd (trapreceiver) shows 'not in time window'

<Resolve> Agent's set_enginetime()function is customized  to calculate
 engineTime depending
on  get_uptime(). This type of customization valid for agent's
engineID's etime and eboot.
Therefore added code to restrict 'calculate engineTime' facility not for
remote-engine(manager's engineID)

 </Resolve>


2. It looks like agent keep retrying to send inform, hence command(above
mentioned) 'snmptrap' got struck and I had to kill the process
I did tried option '-r' but still it will get struck

<Resolve> Disappeared after solving above(1) issue </Resolve>

Hope the solution help others.
Thanks,
Pushpa
