inet | A simple TCP/UDP communication library in C | TCP library

I installed a Kubernetes cluster of three nodes, the control node looked ok, when I tried to join the other two nodes the status for both of is: Not Ready

On control node:

I am a little bit confused about my network setup at home.

This is the setup:

VLAN1 - 172.16.20.0/24 VLAN2 - 10.11.12.0/24

I am in the VLAN2 net (which is my WiFi), for the moment I allowed all traffic between both subnets.

My setup uses a KVM host for most of the services, my firewall lies on this machine and is virtualized (opnsense).

So the KVM network interfaces looks like this:

I have a JBOSS server (7.0) running an application that uses ServiceWorkers, which requires an HTTPS connection. I was able to update the standalone.xml and Eclipse launch configuration to bind my JBOSS server to my local IP (I'll worry about port forwarding later). Connecting to http://192.168.0.197:8080/[application] works just fine, except that ServiceWorkers won't start because it isn't an HTTPS connection. If I try https://192.168.0.197:8080/[application], the connection fails with the browser reporting "unable to connect".

I've researched several documentation sources and can't figure out what needs to be updated. Please forgive any terminology errors - my background is with application programming and networking tends to be the bane of my existence.

This is the pertinent standalone.xml configuration:

I am currently implementing a scheduler for which I need more information on each frame than the message and its standard headers carry. I created an Object containing all the information and now I want to add a pointer to a .msg file pointing to the informatino object. The .msg File is used to tag the information to the frame later on.

For this I have created a new message file.

I'm trying to configure a simple network structure using Vagrant as depicted in the following figure:

As you can see I aim to simulate a hacker attack which goes from attacker through router and reaches victim, but that's not important for the problem I'm struggling with.

This is my Vagrantfile so far (VritualBox is used as provider):

I want to import flora to omnet++ version 5.2.1 I have already successfully imported inet. I downloaded both inet and flora from omnet++ website, Here.

After I added intent, I wanted to do the same with flora, clicked on it and selected build project. But came out this error :

I also tried downloading flora from github and changed its folder name from flora-master to flora, but got the same error.

I am testing the RandomWaypointMobility with a constrained area minX=-3000m, maxX=3000m, minY=-3000m and maxY=3000m. The @displaystrings sets bgp=6000,6000. The result is that nodes in the negative part of the coordinate system are rendered outside the display/canvas area.

Are there some parameters I can use to tell OMNeT++/INET that origo for the coordinate system is at the center of the display/canvas? I have tried

I'm writing a Milter for Postfix, that handles incoming messages in a server (Postfix+Dovecot) with virtual domains and users. Communication beetweend Postfix and the Milter are done with the Sendmail Milter Protocol V 2

I really need that Dovecot (and Postfix by consequence) does not reject messages with invalid recipient, because I need the Milter to do this check (and reject as weel).

This is needed because i'm writing a PEC mail server (Pec stand for Posta Elettronica Certificata, that is an Italian implementation for certified mail).

When receiving mails with incorrect recipient, I need to produce a specific receipt in a form of an e-mail.

But Postfix in this case (told by dovecot) reject the mail BEFORE sending it to the Milter.

I've tried to search this in the documentation, but were not able to find this specific need.

I've attached PostFix configuration....

I have a header file where i keep all my global variables without assigning a value and i include it in main code like this. I need to access a variable declared in Globals.h from Receiver.c, when i use any variable from Globals.h in Receiver.c, it Eclipse says Unknown Type Name

As per compiler, if i call Globals.h once, its in compiler memory right?

i dont include anything in Receiver.c
