This is an SNMPv3 issue where SNMP traffic between a manager and agent contains incompatible values of snmpEngineBoots and snmpEngineTime. Despite the name this issue is not due to wall time (GMT) settings on the manager or agent.
For a description of these scalars see http://net-snmp.sourceforge.net/docs/mibs/snmpFrameworkMIB.html Here's a simplified explanation of the problem, leaving out some key concepts regarding proper SNMPv3 communication: The agent increments snmpEngineTime once per second. When operating properly the manager is aware of this value, and includes it, along with snmpEngineBoots, in communication with the agent. When the agent's snmpEngineTime reaches a certain threshold, it's reset to 0, and the agent then increments snmpEngineBoots by 1. Both of these counters are part of the security model of SNMPv3. When used correctly they help prevent replay attacks. When the manager's and agent's snmpEngineTime differs enough (over 160 seconds? probably also implementation specific), the agent will send a usmNotInTimeWindows error to the manager. So this error is most likely due to your manager not keeping updated values of snmpEngineTime and snmpEngineBoots. -- Nate > -----Original Message----- > From: sanjaykumar [mailto:sanjay.ku...@globaledgesoft.com] > Sent: Thursday, October 15, 2009 7:12 AM > To: net-snmp-users@lists.sourceforge.net > Subject: SNMPERR_NOT_IN_TIME_WINDOW > > Hi All, > I very frequently get the error > "SNMPERR_NOT_IN_TIME_WINDOW". > > What are the reason for this ??? > where shall I look to resolve this issue ?? > Does it depends on the current time of agent and manager system ??? > > Regards, > Sanjay > > ----------------------------------------------------------------------- > ------- > Come build with us!
