ssh a nohup command
I have a script I'm creating to spawn netcat listeners on a remote server for copying files at high speeds. The issue I'm running into is that after running the "nohup nc -l -p 12345 | tar -xvf - &" commands I can't get the remote shell to terminate. I'm not sure if this is working as intended or I'm missing something, but a simple test can reproduce the same results:

At a bash shell run the following:

nohup sleep 1000 &

exit

The shell clears screen and hangs until the sleep process is killed or finishes. If you check the process though you can see the shell is no longer the parent process:

[root@test ~]# ps -fea |grep sleep |grep -v grep
root 6990 1 0 12:15 ? 00:00:00 sleep 1000

So, beyond having a comment in my script to have users "ctrl-c" to continue, does anyone have a more elegant solution to kill the shell on the remote server?

nohup

NOHUP(1)							   User Commands							  NOHUP(1)

NAME

       nohup - run a command immune to hangups, with output to a non-tty

SYNOPSIS

       nohup COMMAND [ARG]...
       nohup OPTION

DESCRIPTION

       Run COMMAND, ignoring hangup signals.

       --help display this help and exit

       --version
	      output version information and exit

       If  standard  input  is a terminal, redirect it from an unreadable file.  If standard output is a terminal, append output to 'nohup.out' if
       possible, '$HOME/nohup.out' otherwise.  If standard error is a terminal, redirect it to standard output.   To  save  output  to	FILE,  use
       'nohup COMMAND > FILE'.

       NOTE: your shell may have its own version of nohup, which usually supersedes the version described here.  Please refer to your shell's doc-
       umentation for details about the options it supports.
