port

Port scanning and banner grabbing.

Usage

r4t port <subcommand> <target> <port> [flags]

Check whether a specific port is open on a target host.

# Check if port 445 is open (TCP)
r4t port scan 10.10.10.10 445

# Check a UDP port
r4t port scan 10.10.10.10 161 --udp

Flag	Short	Description
`--udp`	`-U`	Use UDP instead of TCP

Returns open/closed/filtered status.

Connect to a port and retrieve its service banner.

# Grab the banner from port 22
r4t port banner 10.10.10.10 22

# Grab banner via UDP
r4t port banner 10.10.10.10 161 --udp

Flag	Short	Description
`--udp`	`-U`	Use UDP instead of TCP

Connects to the target port, reads the initial server response, and displays it. Useful for quick service fingerprinting without a full port scanner.
