kandi X-RAY | IPAddress Summary
Library for handling IP addresses and subnets, both IPv4 and IPv6. In the Maven Central Repository, packaged as an OSGI bundle, packaged as a Linux Fedora rpm, in Apache Archiva on Wikimedia. As a Java library, it is also interoperable with Kotlin, Scala, Groovy and Clojure. In progress: port to Go.

QUESTION
I am porting some C code to C++ right now. The C code is using multiple defines like:
#define IPADDRESS "fd9e:21a7:a92c:2323::1"
The problem that i have is that when i am calling C functions with the defines that are now in the C++ file i get:
warning: ISO C++ forbids converting a string constant to ‘char*’
I don't want to modify the C functions in this case and since I am still new to C++ and i was wondering how to handle this problem. I guess it isn't possible to tell C++ to handle these defines as a char*
and not as a string constant
so i was wondering if it is safe to cast the string constant
to a char*
in this case or if there is a function that i should use for this?
I appreciate your help!
...ANSWER
Answered 2021-Jun-14 at 12:44The problem is that string literals "this is a string literal"
are of type char[]
in C but const char[]
in C++. So if you have sloppily written C code which doesn't use const correctness of function parameters, that code will break when ported to C++. Because you can't pass a const char*
to a function expecting char*
.
And no, it is generally not safe to "cast away" const
- doing so is undefined behavior in C and C++ both.
The solution is to fix the original C code. Not using const correctness is incorrect design, both in C and C++. If the C++ compiler supports compound literals, then one possible fix could also be:
QUESTION
Started to develop a wiresless 'cable' solution (with websockets) between two ESPs, a wireless serial 'cable' between computer and a serial device to mimick a direct wired connection. Was working great however just accidentally fried one of the ESPs (short a serial cable connection to higher voltage - sigh) when testing. Replaced one of the ESP32s with an ESP8266. Suspect this should work however it did not.
The problem is the ESP8266 (client) cannot find the network of the ESP32 (server). Why it doesn't work? My computer can see the server and can connect. Fried ESP32 the same, no problem.
Tried the WiFiScan demo on the ESP8266 and can detect all other WiFi SSIDs/MACs in neighborhood however cannot detect the ESP32 server it's SSID/MAC.
Why it doesn't work? What is the difference and how can I solve this?
ESP32 - code of the server
...ANSWER
Answered 2021-Jun-14 at 07:45WiFi channels 12-14 are not used in some countries (e.g. US). Perhaps the ESP32 AP picked one of those channels, and ESP8266 is configured by default with settings from a country which doesn't allow them. Set the AP channel to some reasonably safe value in range 1-11.
I can see that the default channel should be 1, but I'd suggest experimenting with it, perhaps setting it to 6:
QUESTION
I need to parse a XML file having the structure as follows: (I can't show the data as it is confidential)
...ANSWER
Answered 2021-Jun-12 at 17:26As mentioned in comments your xml document has namespace definitions in its DocumentElement (
xmlns
stands for xml name space). Furthermore "it contains a default namespace so any attempted parsing on named nodes must map to this namespace URI otherwise returns nothing."
To allow eventual analysis it's necessary to include a user defined prefix (e.g. :s
) into explicit namespace settings, which can be used in later XPath expressions:

I was using this technique (How could I retrieve AWS Lambda public IP address by using Python?) but it gives the IPAddress of the Lambda Server within AWS.
Based on this: How can I retrieve a user's public IP address via Amazon API Gateway + Lambda (node), it looks like I should be able to use
...ANSWER
Answered 2021-Jun-07 at 08:00You can try this:
- Add the X-Forwarded-For to the "HTTP Request Headers" (goto the API-Gateway configuration -> Resources -> Method Request).
- Add a Template with Content-Type: application/json (Resources -> Integration Request -> "Mapping Templates")
- Add a Mapping to the template

So, I'm very new to Docker and I'm trying to use it to containerize an ASP.NET (Framework 4.7.2) application. My platform is Windows 10 and the application is to run under a Windows container. Here's what I've done:
- Click on "Add -> Docker Support..." when right-clicking the project in Visual Studio.
- Waiting for it to generate a Dockerfile.
- Clicking "Run".
A generic 500 IIS error pops up when Chrome launches, and it opens at IP 172.26.102.145 rather than localhost:port, like it normally does when running without Docker. I looked at the event logs and this is what I see:
...ANSWER
Answered 2021-Jun-07 at 23:00This problem turned out to be a red herring, with the real issue found by looking at IIS application logs within the docker container. I suggest anyone facing this to open up powershell in the container by running:
docker container exec -it powershell
Then browse the application logs with:
Get-EventLog -LogName Application -Newest 15
You may see an issue there. Also, you can try running this in the container to see if an error is spit out:
Invoke-WebRequest http://localhost

QUESTION
I'm trying to parse a config file into a python dictionary. I can't change the syntax of the file.
I'm using pyparsing. Here is my code so far.
...ANSWER
Answered 2021-Jun-05 at 23:02Parsing a recursive grammar always takes some extra thinking. One step I always always always encourage parser devs to take is to write a BNF for your syntax before writing any code. Sometimes you can do this based on your own original syntax design, other times you are trying to reconstruct BNF from example text. Either way, writing a BNF puts your brain in a creative zone instead of coding's logical zone, and you think in parsing concepts instead of code.
In your case, you are in the second group, where you are reconstructing a BNF based on sample text. You look at the example and see that there are parts that have names, and that it looks like a nested dict would be a nice target to shoot for. What are the things that have names? Some things are named by a 'name = a-value'
kind of arrangement, other things are named by 'name structure-in-braces'
. You created code that follows something like this BNF:

is localhost which means by definition the server is only reachable on the same host.
If you want the server to listen on all interfaces don't specify IPAddress.Any
respectively IPAddress.IPv6Any
or use 0.0.0.0.

Install IPAddress
You can use IPAddress like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the IPAddress component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
