privacy – Would a web server that replies to all requests with all responses be capable of achieving web traffic that cannot be traced between any two clients?

Consider a scenario where Client 1 wants to share information with Client 2 over a network fully monitored by a state actor, and achieve that communication while hiding:

  1. what each party sent.
  2. what target party each other party intended to communicate with.

Tor attempts to achieve this, however if the state actor hosts enough nodes of its own, it can create a high enough probability of hosting each party’s connection to eventually identify the parties communicating.

To avoid this vulnerability:

  1. Client 1 and Client 2 share a private encryption key in some manner that escapes the notice of the state actor, even if that means a physical exchange of USB drives.
  2. Then they connect to a node which waits for millions of requests to occur, each containing encrypted information to be communicated, bundles it all together, and sends the entire bundle of information back to every client involved.
  3. Client 1 and 2 then attempt to decrypt every item in the bundle until they successfully decrypt the information created with their private key.

The monitoring state actor would not be able to determine which client communicated with which other client, nor what anyone communicated, so long as they shared their keys privately. Even if the state actor took over the Privacy Node, it could only know which clients attempted to connect to it, not what they sent nor who they intended to communicate with. Nor could it spoof any response to the clients without knowing their keys.

Is there a flaw in the concept I’m considering? If so, what?

nomad – How can I create a Hashicorp Consul cluster across the Internet and LAN clients?

I want to create a Consul cluster with some Raspberry Pi computers and a central server on the Internet. Each of the RPi computers will be on a different LAN.

NOTE: I appreciate that having a single Consul server is not suitable for production, but this is an idea I am playing with.

I have configured the Consul server on the Internet and have enabled ACLs for both of the software. I have installed Consul on the RPi computers and indeed they can communicate with the central server, but the health check is flip-flopping from healthy to not-healthy.

Looking into this I think it is because the address that the client has advertised the LAN address to the server rather than its WAN address. I have tried to use the advertise_addr_wan and translate_wan_addrs options but this has not helped.

I have been looking at the architecture diagrams for Consul and see that it is possible to connect servers across the WAN from different data-centres but not (obviously) clients. Do I need to run a server and a client process on each of the RPi so that each one is its own Data Centre and then connect the DC servers together across the WAN?

After I have set this up I want to configure Nomad to use Consul and have a Nomad agent on each of the client RPi computers. I assume that I will encounter similar issues with IP addressing. Am I correct?

I do not want to resort to having to run a VPN for all the traffic between the nodes nor do I want to install Docker and run Kubernetes because the app I will be deploying is not natively in a container.

Any ideas on how to accomplish this is very gratefully recieved.

(I original, incorrectly, posted this on Stack Overflow, I hope this is the correct forum for a question of this type)

windows 10 – sharing laptop, 2 VPN clients, but only one GUI

The problem is that 2 people are sharing one laptop running windows-10, so they want to use VPN (different software, one is CISCO the other I dont know) but there is only one GUI on the laptop. So one connection is fine, but the other does not show the screen/GUI. Any advice?

Where to start freelancing for clients? |

Freelancing is one of the difficult work that one can do these days. Because when I started working on task based freelancing. There was only fiverr and upwork. And now that upwork is extremely expensive because it even takes money from the freelancers to send the offers. So it can be pretty expensive when it comes to working on freelance projects. And fiverr is even more harder considering people bid to low amount.

So if you were to start freelance career where do you start and how do you get new clients?

Static IP for VPN clients

I’d like to know if I can assign static IPs for VPN clients (on virtual network interface) using NordVPN. If not, then which VPN provider (except OpenVPN) allows to assign static IPs for clients.

Linux networks: load balancing between regions: how to run two haproxies and serve geographically close clients

You may be asking this question incorrectly, so feel free to suggest changes if necessary.

I run a web service. For both reliability and horizontal scaling, the front-end is a haproxy with two nginx instances behind it. The haproxy is a single point of failure, something I would like us to grow from.

More importantly though, our users in other regions (i.e. continents) see slow service. We know how to improve this with servers by region: adding an existing (Iowa) to the existing (Frankfurt). Two haproxy instances (one in FRA, one in IOA) and the key additional services each needs at low latency.

What is less clear to me is how to serve users.

User A makes an HTTPS request to DNS says look at (all the IP addresses in this question are obviously bogus). This already presents the first problem. We have (in FRA) and (IOA). How does DNS know which to point the user to? Note that RR-DNS, often suggested in this context, is inappropriate: it ignores load, availability, or proximity, and you may experience caching blindness. Virtual IP addresses could they work, but if they do, it seems to require us to run internal gateway protocols like OSPF. I don't think it's a sensible thing for us to do, and I'm not sure if our service provider will allow it anyway, but I could be completely wrong. I don't fully understand VIPs. Floating IP it can be used for failover, but it also fails by ignoring proximity or account load.

AWS, Google, Azure, and surely others provide services that handle this type of load balancing, but they all assume that you are running their entire service on your infra. It bothers me greatly that the only solution to this problem is to accept the provider block.

I have read a little about GeoDNS, which sounds promising. (AnycastOn the other hand, it requires that the DNS server be placed with our haproxy. And it may require ISP support).

Any solution would seem like a hugely complicated SSL certificate issuance.

Can anyone point me in the right direction on how to approach this?

networking: keeping clients updated with server status in an mmo game

I'm making an online role-playing game that could be classified as an MMO, but I keep the scope of the project very small by simplifying the game's systems and focusing mainly on what I want to learn: real-time networking.

The problem I am facing is that I don't want to update all players over all other players, all the time. This is a huge loss of bandwidth, and it may even be impossible without a really robust connection.

My solution is:

  • Keep track of the entities that are in the client's visibility range.
  • Send a "full entity status" package when the customer enters the world
  • Submit a "create entity" package for any entity that enters the visibility range
  • Submit a "remove entity" package for any entity leaving the visibility range
  • Submit an "update entity" package for any entity that updates within the visibility range

I don't like the fact that when the client moves I have to update the list of entities that it can see, because it means I still have to loop through all the entities. Is there anything better? Can this solution be improved in any way? If so, could you please provide more readings, or possibly even sample implementations?

database: return the number of clients with more than one withdrawal per day for the last 3 months on mongodb

I have a collection & # 39; CustomerSaque & # 39; with these fields:

"_id" : LUUID("952d4af5-1e5a-de4e-b1bf-3abe38edbaaf"),
"UsuarioNome" : "Joao da Silva",
"CpfCliente" : "99999999999",
"Valor" : "824.50",
"DataHora" : ISODate("2020-05-05T07:37:30.695-03:00"),

How would you return the number of clients with more than one withdrawal per day in the last 3 months?
