I'm trying to test if a service is up and running using nc.
echo ruok | nc 127.0.0.1 5111
But I get this response:
This is nc from the netcat-openbsd package. An alternative nc is available in the netcat-traditional package. usage: nc [-46DdhklnrStUuvzC] [-i interval] [-P proxy_username] [-p source_port] [-s source_ip_address] [-T ToS] [-w timeout] [-X proxy_protocol] [-x proxy_address[:port]] [hostname] [port[s]]
I'm not sure how to use this 'alternative nc', can someone please explain this to me?
echo ruok | nc -s 127.0.0.1 -p 5111
but I got the same message.
