Re: [nmap-svn] r29382 - nmap-exp/kroosec/rpc-grind/nselib

Hello,

I think that the following patch should be ported to trunk. Nmap
currently doesn't even connect to RPC services if not run in
privileged mode. I agree that attempting to bind to a <1024 port is a
good thing to try but if not possible that shouldn't stop the
execution flow.

Regards.
