Guest · Posted: Fri Jan 13, 2006 1:39 am Post subject: netcat (nc-1.82-fc4.1) + FC4

it should be noted that nc in FC4 does not allow you to do:

nc -l -p 9000 (as shown on the documentation for device-image)

this is straight from nc's manpage:

-l Used to specify that nc should listen for an incoming connection
rather than initiate a connection to a remote host. It is an
error to use this option in conjunction with the -p, -s, or -z
options.

Instead, I think all you have to do is omit the "-l" and just do "nc -p 9000" etc etc...

oops that last part should be

"nc -l 9000"

Hi,

thank you for this hint. I think that following in the documentation should be mentioned:
The usage of options for nc in this docu is based on the man page of original implementation of netcat by *Hobbit* <hobbit@avian.org>.
Any deviations from the original implementation may have other options which need to be considered.

Example: netcat for Fedora Core is re-written nc(1) for OpenBSD with different usage of -l and -p options.

Regards,
Jurij
