How is this one EB> generated? First, make sure you understand the difference between TRAPs and INFORMs with engineIDs. It's not as easy as you think ;-) Here's a web page talking about it: http://www.net-snmp.org/wiki/index.php/TUT:snmptrap_SNMPv3 The default engineID generation for net-snmp is based on a random value and the timestamp the first time the application is run. If an old engineID is found in the /var/net-snmp config file for an application it is always used instead (since the engineID shouldn't change from run to run). -- Wes Hardaker Cobham Analytic Solutions ------------------------------------------------------------------------------ _______________________________________________ Net-snmp-users mailing list [email protected] Please see the following page to unsubscribe or change other options: https://lists.sourceforge.net/lists/listinfo/net-snmp-users
