How to send 0x80 byte to a tcp port using netcat or similar tool?

Question

I'm trying to make a Memcached server respond as if I were using a binary protocol. If possible just command line answers pls, no code snippet in any programming language.

Just use:

echo -e '\x80' | nc host port

I needed to send two bytes; this worked for me: `echo -e '\x04''\x03' | nc host port` – 11101101b Oct 02 '15 at 14:30

You do not need to quote every escape sequence, just leave it between the same single quotes. – Florin Asăvoaie Jan 14 '16 at 09:29
