Hm, two things I use that seems to be missing in ncat vs. the nc available on debian:
-q secs quit after EOF on stdin and delay of secs
-k set keepalive option on socket
The -q argument is somewhat like ncat's --send-only, except that it allows receiving data too, as
long as you haven't closed stdin yet. I use that one a fair bit. Generally as -q0. I want the client to
be able to send and receive data, but to be in control of closing the connection.
The -k option is pretty self-explanatory -- it's useful when you're going through firewalls.
Although really, I don't know why SO_KEEPALIVE isn't just on by default in the network
stack with a timeout of 8 minutes, these days...
