Bug ID: 212162
Summary: netcat (nc) does not close TCP stream / exit after end
of input stream
Product: Base System
Version: 10.3-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
To reproduce, use two terminals. In the first, execute:
$ nc -l 2222
In the second terminal, execute:
$ echo "hi" | nc localhost 2222
This command will hang.
My expectation is that nc will terminate once the end of the input stream is
reached.
Contrast with the behaviour of socat, which seems correct. Try this command:
$ echo "hi" | socat - TCP:localhost:2222
Both listener and sender processes exit.
