You should specify more parameter on command line, such as destination port.

Dear all,
I have the same problem, although I used port option, can anybody help me to solve this problem?

Thanks in advance,

What your libnet version? Packit 1.0 requires libnet 1.1.2 or greater.

Thanks for your reply
When I add -c option for example packit -d 10.1.1.10 -c 100, it start sending when finish sending 100 packits the privous error appear. what does mean?why this happen?
How I do know my libnet?

The packit may have a bug. You can apply the pacth, http://sources.gentoo.org/cgi-bin/vi...ch?view=markup

How I do know my libnet?
Check libnet version: strings $PATH_TO_LIBNET/libnet.a | grep version

when I write previous command: strings $PATH_TO_LIBNET/libnet.a | grep version
I get following error : strings: '/libnet.a': No such file
why??
Thanks

How apply the patch and where?
Thanks

The PATH_TO_LIBNET mayn't be setup. Normally, the libnet.a should be under /lib directory.

You need download the source code of packit and then apply the patch. And then compilering code, installing and trying it again.
