SNMP Agent simulator (Net-SNMP/PHP)

For instance this is usefull for offline-development of new check-plugins. You don’t need physical access to the SNMP server running the agents. All you need is a numeric SNMP-dump of the actual tree you are interested in, which may be obtained in a single on-site run. An example of the LanManager (77) tree beyond enterprises (1.3.6.1.4.1) could look like: * snmpwalk -O n -C c -c public -v 2c myhostname 1.3.6.1.4.1.77 | sort>lanmgr.dump While some agents don’t supply OIDs in increasing order, we can work around that using “-C c” and “sort” in this example. As soon as you are done with this just copy the output (here “lanmgr.dump”) and integrate it into your own SNMP daemon. In order to add the LanManager tree to your local Net-SNMP daemon you would add the following line to /etc/snmp/snmpd.conf: * pass_persist .1.3.6.1.4.1.77 /usr/local/sbin/mySNMPagent.php /tmp/lanmgr.dump Please note, that NET-SNMP may take a long time to start up and load what you specified behind pass_persist commands! It will result in "No Such Object available on this agent at this OID" messages and may take a few minutes to load even on new hardware! ATTENTION: this is a tool in very early stage of development. While it may be useful for a lot of cases, there was no heavy testing so far. Multiline hex-output is not yet supported. Other stuff may be missing.
