TCPDUMPING: tcpdump is a data-network packet analyzer computer program that runs under a command line interface. It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached.
SNMPWALK: SNMP walk is an SNMP application that uses SNMP GETNEXT requests to collect SNMP data from network and infrastructure SNMP-enabled devices, such as switches and routers.
REMOTE ACCESS: The act of being able to access and work on a different PC than the one you are currently using.
SNMP SETUP
