Yes, it can. The default is to log to /var/log/snmpd.log, but you can set it up to log to syslog. Check out the man page for snmpd. Search through the code for snmp_log for example usage. AC> 2.

The SNMPv3 RFCs specify how authentication is done. You can poke about in snmplib/snmpv3.c to look at code. Try using a debugger to follow the whole process that our agent uses. AC> 3.

Again, the SNMPv3 RFCs specify how authentication and encryption work. Currently, there is no such thing as a SNMPv3 session. Our api uses a 'session' structure, but it is entirely a local thing. Opening a session does not communicate with the remote agent. If a message is lost, the library will retry based on the session parameters. Eventually the library will return a timeout to the application. -- Robert Story; NET-SNMP Junkie Support: <http://www.net-snmp.org/> <irc://irc.freenode.net/#net-snmp> Archive: <http://sourceforge.net/mailarchive/forum.php?forum=net-snmp-users> You are lost in a twisty maze of little standards, all different. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
