ping a port with specific packet /my own packet

Question

Is there a way to ping a specific port with my own packetsize? Can I create my own packets lets say using a packet builder and send them without a MAC address of the receiving machine?

Answer 1

1) Ping is simply a specific type of ICMP Message. ICMP Messages sit directly on top of IP and thus there's no concept of a port, since that's introduced by TCP.

2) You must specify a MAC Address in all your packets. It can be the one of the device you're trying to ping.
