kandi X-RAY | Nscan Summary

Nscan is a Python library typically used in Utilities applications. Nscan has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However Nscan build file is not available. You can download it from GitHub.

Nscan is a fast Network scanner optimized for internet-wide scanning purposes and inspired by Masscan and Zmap. It has it's own tiny TCP/IP stack and uses Raw sockets to send TCP SYN probes. It doesn't need to set SYN Cookies so it doesn't wastes time checking if a received packet is a result of it's own scan, that makes Nscan faster than other similar scanners. Nscan has a cool feature that allows you to extend your scan by chaining found ip:port to another scripts where they might check for vulnerabilities, exploit targets, look for Proxies/VPNs... Nscan is a free tool, but consider donating here: 1Gi5Rpz5RBEUpGknSwyRgqzk7b5bQ7Abp2.

Pasting your code into godbolt quickly reveals the problem. struct stat isn't defined. For linux, you need to #include and #include for struct stat. Pay attention to the remaining warning(s).

If the format is always in the same order you could look into using the grok filter plugin: https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html

The pattern i think might do the trick, if you want to use the numeric value of the time as seconds you can change the pattern a bit, as well as for the file size...:

...

ANSWER

Answered 2020-Aug-05 at 07:20

I don't believe that bluetoothctl was intended to be used in this way. The BlueZ developers are always changing bluetoothctl which will break your script if you get it working.

The better way to do this is use the D-Bus API that BlueZ provide

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/adapter-api.txt

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/device-api.txt

To do the you will need to know:

The BlueZ service is 'org.bluez'
The adapter device has the D-Bus object path of '/org/bluez/hci0' typically
The DBus interface for the adapter is 'org.bluez.Adapter1'

MongoDB queries spending lots of time on Global.timeAcquiringMicros.r

Asked 2020-Jun-10 at 11:13

I am using MongoDB version 3.0.14 (with wiredtiger) as 4 member repliate set. I am facing a strange issue in production where suddenly most of the queries start to block on Global.timeAcquiringMicros.r (on Secondary Mongod Server, where the java-client is sending normal read queries using SecondaryPreferred Read Preference)

...

ANSWER

Answered 2020-Jun-10 at 11:13

A MongoDB secondary node retrieves operation log events from the primary in batches. When it applies a batch of oplog events, it takes a global exclusive write lock (W).

A read intent lock(r) is mutually exclusive with the W lock.

This means that writes and reads must interleave on the secondary nodes, so heavy writes can block reads, and heavy reads can delay replication.

Non-blocking secondary reads was a major feature of MongoDB 4.0 a couple of years ago.

If you can upgrade, that specific lock contention should not happen anymore.

QUESTION

Faster way to convert ctypes array to python list?

Asked 2019-Jun-05 at 19:44

I was wondering if someone could advise me whether there is a better/faster approach to read data from my C program that outputs two lists of size n. I am using ctypes to call the C program.

The loop I show below works by iterating over a number of scans. For each scan two lists are produced (msX, msY). The c_float data is extracted by using list comprehension loop. Is there a better/faster way to convert the c_float_Array obtained from mzP and mzI to msX and msY?

...

ANSWER

Answered 2017-May-25 at 12:40

The answer is to use NumPy. You can use NumPy to allocate an array, pass a pointer to its data to your C API which will populate it, and then at the end if you are desperate for a list you can call tolist() on the NumPy array. However, you will likely find that keeping the data stored in a NumPy array instead of a list allows you to accelerate downstream processing.
