Package netcat

OpenBSD netcat to read and write data across connections using TCP or UDP

https://man.openbsd.org/nc.1

The OpenBSD nc (or netcat) utility can be used for just about anything involving
TCP, UDP, or UNIX-domain sockets. It can open TCP connections, send UDP packets,
listen on arbitrary TCP and UDP ports, do port scanning, and deal with both IPv4
and IPv6. Unlike telnet(1), nc scripts nicely, and separates error messages onto
standard error instead of sending them to standard output, as telnet(1) might do
with some.
