** Short description from [1] **
I have created a patch to NSE that replaces runlevels with a table of
dependencies that clearly outlines what other scripts the script
depends on. The table is of the form:
dependences = {"script1", script2", ...}
Runlevels become an internal representation of the order of scripts
that are generated by the dependencies. Dependencies only enforce
an execution order and not a requirement for execution.

sending the second probe if the first caused an error. This is based on
the results of a test by Richard Sammet showing that the default timeout
of 30 s is too long when scanning many open|filtered ports that are in
fact filtered.
o Reduced memory usage in several areas. The size of the internal
representation of nmap-os-db was reduced more than 90%. The size of
individual Port structures without service scan results was reduced
about 70%. When a port receives no response, Nmap now avoids
allocating a Port structure at all, so scans against filtered hosts
can be light on memory. Thanks to Pavel Kankovsky for the Post size
reduction patch. [David]
changes. The first is that Port objects don't allocate memory for
service and RPC results unless that information is set. This reduces the
size of a bare Port from 92 to 40 bytes on my machine. The second change
is that PortList now has the notion of a "default port state," which is
the state of any ports that didn't receive a response. These ports don't
need an allocated Port object, which saves a lot of memory in scans
where most ports didn't get a response.
decoding the bytes with various Chinese encodings but they were all
gibberish in Google translate. It turns out they are EUC-KRâencoded
Korean, translating to "The server version 6.5.7226.0 (a) has been
prepared."
the code just took each value mod 256 and stored it as a single byte.
The OID 1.3.1000.5 would encode as follows
tag len 1.3 1000%256 5
06 03 2b e8 05
What you're supposed to do is break each value into 7-bit chunks, and
set the high bit in every octet but the last. Now it is correctly
encoded as
tag len 1.3 1000 5
06 04 2b 8768 05
The length also would not have been correct for lengths over 127, and
that is fixed also.
