Simple Socket Server in Bash?

Question

Is there a way to quickly bind to a TCP port/ip address and simply print out all information to STDOUT? I have a simple debugging solution which writes things to 127.0.0.1:4

Answer 1

Adding an answer using ncat that @Freedom_Ben alluded to:

ncat -k -l 127.0.0.1 4444

and explanation of options from man ncat:

-k, --keep-open            Accept multiple connections in listen mode
-l, --listen               Bind and listen for incoming connections
