man in the middle: if I am using a VPN with multiple connections allowed, can each user / device see the traffic of the other user?

If I am using one, a VPN service, but can connect up to 8 devices, can all devices / users see the traffic of other users / devices?

Or is each VPN connection creating its own tunnel, so it basically says that only 8 tunnels can be made / created at a time?
Also, once connected to my VPN, it is possible that someone give me authentication, using my VPN too, if someone is playing with a Wifi network? I mean, in theory, if you can think of something that can be done, but I wonder if this is a problem that happens often.

What I ask is that I am living in a house with several people, sometimes I realize that they have fun upstairs, when trying to configure several access points with the same name of Wifi, I worry if they can kidnap sessions even if I am on a VPN connection (as I once noticed a message on a service that I never wrote, but when I review the session logs, the only open sessions are the ones I know). I know I had I did not write this message, therefore, I am interested in how it would be done if I was on my VPN. Although I realize that they disconnect the wifi, sometimes they make me reconnect to my VPN, etc.
For my part, I set up my VPN to disconnect from the Internet, once my VPN connection goes down, but I wonder if reconnecting immediately could cause another security issue (assuming VPNs have handshakes as a point of wifi access).
Would it be safe to say that I should invest in my own wireless router and set up a firewall? Originally, I wanted to use my Linux box with two wireless cards, set up a new wireless network with a firewall and then create a new Hotspot, protecting my devices a little more.

The central Bitcoin node does not send outgoing connections only incoming traffic

My bitcoin core is not sending outbound connections. You are only getting incoming connections. Iv removed the entire node and then reinstalled it. Still I was just getting incoming connections. Iv verified the firewall configuration and the node is configured to receive incoming and outgoing connections. Does anyone know what the problem could be? Could you synchronize blockchain only with incoming connections?

Does Azure Application Gateway support gRPC connections?

I have configured Azure Application Gateway with Azure Kubernetes Service. The gateway works with the sample guestbook application, everything works without any problem.

I use a very similar configuration for an application that uses gRPC-gateway. The pod that runs the REST endpoint works correctly; however, the gRPC endpoint cannot communicate with the gateway.

Currently, I am using personalized life status checks and preparation so that the backends (goals) are in the group.

The error message I receive when I see the Health tab of the backend is:

Cannot connect to server. Check whether any NSG/UDR/Firewall is blocking 
access to server. Check if application is running on correct port.

I guess the gateway is not compatible with gRPC, but I'm not sure.

I used the Greenfield tutorial – Application Gateway Input Controller to create the AKS cluster and use the Azure Container Network Interface (CNI) network.

Why does TLS1.2 interrupt connections to SQL Server?

NOTE: requested to move the question from StackOverflow to dba

I don't know if this is really a problem in SQL Server or not.

The client moved to TLS 1.2, broke an application that connects to SQL Server 2017 and was left in my lap.

Being a Linux person, all I can say is that when they returned to TLS 1.1 it worked and here is the only error message I can pick up in all this mess:

dbnetlib connectionopen secdoclienthandshake ssl security error

In SS Studio, when I click on the database, this error message appears:

transit – General rules for close connections on international flights

Usually An airline is responsible for its connection between flights issued on a single ticket. Airports have a minimum connection time that limits how short a connection is allowed when issuing tickets. That time sometimes depends on factors such as terminal changes, but in my opinion it is very optimistic.

When you buy from an external agent, you don't always issue a single ticket and, if that's the case, it's usually on your own, but if it's the same airline, sometimes they deal with your lost connection. In most cases, through the main online travel agencies, they mostly show individual ticket fares with which they are not labeled differently. The last time I saw such an offer, it said Hacker fare below the price

When you lose a connection that the airline is responsible for, they usually book it on their next available flight. This may delay some hours, but in general it is not uncommon since certain segments only have daily flights. During the high season, they vary their strategy in including associated airlines and / or more complicated flights. This can be particularly tiring when all flights are booked for days and placed on each waiting list in the hope that someone will cancel or lose their connection. The same if you were going to miss another connection flight and try to make it catch up with your next connection or take a completely different route.

As for compensation, that varies considerably depending on the jurisdiction. It goes from nothing to hotel and monetary compensation. Better ask another question if you have in mind a region or an airline.

Note: It generally means that there are exceptions in areas, countries, unions and airlines that have their own rules and the interpretation of the law may vary. Finally, even if you have the legal right to something, that does not mean that it will be granted automatically.

Connections that never end …

First I recommend you try this approach.

If that does not work, you can test the configuration >> connection timeouts and other configurations >> other >> min thread threads.

That tries to force the closure of all connections when it reaches the threshold. I like 20%. So, if you are using 100 threads in link checking, then you would set it to 20 for minimum threads of the link checker. Note that if you configure the minimum threads of the link verifier equal to or greater than the total connections of the link verifier, that verification will be terminated instantly when you press start on the link verifier.

Believing or not scrapebox really can't just stop the threads. The point is that scrapebox uses threads / sockets and these are a global convention. Scrapebox did not design them, they are used by programs around the world. These are built in such a way that Windows literally has control over them.

The coding is not as short and dry as it seems. Then Windows literally has control over the threads and if Windows blocks a thread or any third-party software blocks a thread, then scrapebox is forced to wait until it is unlocked.

Windows really doesn't "intentionally" simply block threads probably, unless you don't like the content of a url, but Windows simply wasn't created for scrapebox, so Windows only has "brain farts" if you wish and simply blocks threads sometimes.

On my servers I fight this by working on ultra small pieces. I run the automation and first divide my source URLs into pieces of 100 url, dump them into a folder.

Then have the automation verify link 1, and print the results and then run a custom script that copies to the next file in the folder and then repeat the automaton to verify the link.

This works well, even Google runs everything on small fragments and small servers, since it is more effective than larger machines, etc.

I go one step further, which is probably excessive for you, but I want things to run 24/7/365. Then I have another script that monitors the link checker and forces arbitrary closing every 12 hours. In this way, I lose some links every 12 hours, but you can always reload them to verify them, what you are doing anyway.

When the link checker closes by force, I kill it, scrapebox / automator works and then the script pauses for a few seconds and restarts scrapebox and the automater then starts the link checker again.

Therefore, it works all year without problems, for the most part. There are always anomiles (I have no idea how to spell that, hahaha) of course.

However, minimum link verifiers are probably your best option. You can also activate another instance of scrapebox and cut your list in half, that way if 1 blocks the other, you can only lose half of the work. You can run unlimited instances of scrapebox on a single machine.

As for the windows that have control over the threads, it stinks, but it is the best option that exists, so it is better than the alternative. But you can avoid it. Small list size and more than 1 instance is how I do it.

Slow connections when downloading files through .php files on my website


I have a website on my server and run my website. My website is a download center website for specific fields and files, which visitors and users purchase the desired subscription to download those files.
The download of files is handled through .php files. Let me clarify:

I upload some files somewhere, and each file has an identification in the database.
Users buy subscriptions to download the files.
The download link is something like: in which, 234 is the identification of a file in the database.
When the user tends to download this file and if he uses Windows with IDM integration, IDM downloads the file but only with 1 connection.

The problem starts now: the user has only one connection to download the file. If the file size is 3 GB, the user must wait at least 200 MB to download it, and then they are given more connections to download the file.
Also, when you only have one connection, you cannot download any other files or visit the website.
I have also moved one of these large files to another path so that it can be directly accessible using the link
When I use this link in IDM, I suddenly get as many connections as I can, and I can also visit any other page of my website without any problem.

My control panel: Directadmin
Web server: nginx-apache
My script: my software developer has written it for my exclusive website
I've talked to the developer, but he ignores it and says it's not related to his program.
Recently I have migrated from another server without any CP to the new one. The previous server also used nging-apache.

Something I have done:
I have increased some variables in httpd and nginx, but I still have problems.
I tried switching to just apache or even nginx, but it didn't resolve.

I see that Apache handles these files and Apache downloads them, because when the user is downloading with only one connection and then tries to visit the website, I see some logs of timeout errors in the apache logs.

Could you please help me, what should I check? Do you think it could be resolved at the end of the server?

Thanks in advance

sharepoint server – Configure web part connections Query string URL filter programmatically

I am trying to configure the url filter web part connections of query string with JSOM. The connections do not seem to be stored in the properties of the web part, so I don't know how I can edit them programmatically.

Specifically, I am trying to edit the web part connections accessible as well from the graphical user interface:

through JSOM. I am trying to completely configure the Web filter URL query string with JSOM.

Language and its mathematical approach with respect to logical connections.

How do you express something that is beyond the limits of language? Does language infer pronunciation or is some form of non-auditory or stereo communication considered language?

sql server – How to visualize connections between internal queries to their respective external queries?

It seems that I always have trouble visualizing what the meaning is when an internal query joins its external query.

Here is an example:

SELECT NM.MovieId, NM.MovieTitle
FROM NinjaMovies AS NM
    FROM Ninjas AS N
    INNER JOIN NinjaWeapons AS NW
        ON N.WeaponId = NW.WeaponId
    WHERE N.NinjaId = NM.NinjaId

Is there a way to represent this (or a similar type of internal query attached to an external query) in a table or diagram?
