This tool sends a TRAPv2 to a SNMP server. It permits to alert a server. Parameter --version defines SNMP version to use (from 1 to 3). Versions 1 and 2 need --community parameter to set community name. Version 3 requires --username and --password. Parameter --authmd5 indicates if md5 authentication is used. Parameters --authoritativeengineid, --authoritativeengineboots, --authoritativeenginetime, --contextengineid and --contextname are optional version 3 parameters. Parameter --display shows packets. Parameter --dst-ip is the address of remote host/server. Parameter --dst-port is the port number where to connect. Optional parameter --src-ip defines the local IP address to use. Optional parameter --src-port defines the local port number to use. Optional parameter --ip4opts permits to add IP4 options encoded as mixed. Optional parameter --ip6exts permits to add IP6 options encoded as mixed (first byte is the next header number). Optional parameters --device, --src-eth and --dst-eth permits to create a virtual client using fake addresses (in this case, tool have to be run with admin privilege in order to sniff and spoof at Ethernet level).
