possibility of 'nc' supporting '-l' ? was: Re: [BusyBox] telnet daemon

[Tom Oehser]

I suppose -e would be too much to hope for.  The way I actually use it is:

 c7:5:respawn:/usr/bin/nc -l -p 23 -e /usr/bin/telnetd

in a sysv inittab where /usr/bin/telnetd is:

 #!/bin/sh
 /bin/dd count=1 > /dev/null 2>&1
 /usr/bin/ile /bin/ash -i

(the dd just throws away some telnet protocol garbage, then it works
because ile has a pseudo tty).
