Did not remove calls to stdnse.silent_require since these can be used to
abort script execution if OpenSSL is not included, even if the script
does not directly call openssl.* (perhaps it uses comm.tryssl instead,
for instance).
Also did not remove require "strict", since that library is special and
modifies the environment.
The script was checking the returned data, but not the status. When
status is false, data is actually an error message. So in case of a
timeout, the script was receiving nil, "TIMEOUT" and interpreting
"TIMEOUT" as a response from the server. It looked like this:
Discovered open port 1434/udp on 127.0.0.1
NSE: rpc-grind: RPC checking function response data is not RPC.
NSE: Target port 1434 is not a RPC port.
This was reported by Christopher Clements.
http://seclists.org/nmap-dev/2012/q3/685
NSE: rpc-grind Connect(): RPC library does not support: nil protocol
NSE: rpc-grind Connect(): RPC library does not support: rpcbind version
81578896
These errors caused by ChkProgram and ChkVersion called from
rpc.Comm.Connect. Added a dummy program in rpc-grind and a check for
self.checkprogver in ChkVersion, and everything works great.
Also fixed portrule to only fail if the non-rpcbind service name was not
the result of table lookup. Was failing on port 2049 (in nmap-services
as "nfs") without -sV.
