netcat - unable to put CLIENT IP into $VAR

Question

netcat with verbose captures client IP.

but I can not put it in a variable.

VAR=$(nc -v -l 82)

is there a way to get the sender's ip into a $VAR ?

Note:

Verbose mode only prints extra lines on the terminal.
it does not place that data into the $VAR

Answer 1

The output is probably going to standard error. Redirect standard error to standard output to capture it:

$ VAR=$( nc -v -l 82 2>&1 )

or, you might want to redirect the original standard output to a file:

$ VAR=$( nc -v -l 82 2>&1 >output )
