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.
relinquishes its lock. We expect only one of them to be able to grab the
newly freed lock, and the rest to go back to waiting. This seems to have
helped with a deadlock in running a large-scale favicon survey.
three. This corresponds to the 2 spaces now used in Ron's
stdnse.format_output function for further levels of indentation. The
first level is still special in that it contains "| " or "|_" rather
than just spaces. Here is example output from before this change:
