Nc

Netcat

installation: in terminal type: yum install netcat

execution: nc [-46DdhklnrtUuvz] [-i interval] [-p source_port] [-s source_ip_address] [-w timeout] [-X proxy_version] [-x proxy_address[:port]] [hostname] [port[s]]

reverse shell: netcat is usually good for establishing a reverse shell from a host to a server in order to bypass a NAT that would normally require port forwarding to be set up. i will try to get this working on the XO and explain how it is done
