I was setting up a database on mongodb for a project. Navigated to my own public IP address from firefox and got scared by this certificate error.
I asked the support at https://whatismyipaddress.com/ and they said it's unexpected behaviour.
I don't have control over this network as I am a renter.
Probably a trivial misunderstanding for someone who understands networks but I want to understand why this happens if there's potentially sensitive information in certificates.
Thanks
windows 10
firefox 98.0.1 (64-bit)

I use CheckPoint VPN to log in to my place of work's servers to work remotely. The VPN has been working (mostly) fine all year, and I haven't changed any of the settings, but this morning, when I tried to log in, it's giving me the "Arg_NullReferenceException." I can't seem to find anything on this particular error on google.
I have tried restarting my computer, because it's not the first issue I've had with CheckPoint VPN (though it is the first time I've seen that error message), and a restart usually resolves whatever issue I'm having. I've also tried creating a new connection with the same settings, but I'm getting the same error with that one, too.
I'm not entirely sure what other information I would need to provide. I'm also not sure if it's a problem on my end, or on the company servers. I have already emailed tech support, but I thought I should be thorough.
This is a known issue. I have been jumping through hoops trying to get the capsule client to work. Raise a ticket with TAC if you have support. If not then you can download the E86 Endpoint connect client and run it. That has been my work around for this issue.
They just issued an update to the Capsule via the Microsoft Store. It seems one of the recent Windows Security Update broke the L2TP protocol within windows.
I'm trying to disable network discovery on Win10 for Public and Private networks via GPO, but it doesn't seem to be working as expected. I've attempted the instructions here: https://alferkwok.wordpress.com/2011/07/20/disable-network-discovery-by-gpo-windows-vista-or-later/
- Enabled the following policies and checked the box "Allow operation while in domain":
- Turn on Mapper I/O (LLTDIO) Driver
- Turn on Responder (RSPNDR) Driver
Then, I checked the Control Panel (Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings) and it looks like network discovery is still enabled across Public and Private networks. Any idea why this is? Maybe I'm looking in the wrong place? Any help is greatly appreciated!
So, it turns out that if the Windows Defender firewall is off, then the GPO won't apply. Not sure why this is, though I theorize that, since the Defender firewall is responsible for creating rules about different network location types (domain, public, private), it doesn't accept any GPO because it's not in charge of making rules for those location types when it's off.
I know that some others lately have been getting "HTTP 429 Too Many Requests".
Yet I am having a strange issue with it that I have not seen here nor on streamlink nor youtube-dl's issue tracker.
On my older Vista PC that I use youtube-dl or streamlink at times to get a video have randomly gotten this error since Thur 11/28.
Strangely though, both programs on my Ubuntu 18.04 do not give this error ever.
How exactly is YouTube tracking which PC is sending them the request? I mean both requests would use my same public IP yet Vista is refused even if I don't request for 24+ hours but Ubuntu always works?
I'm looking for a solution to find out about the MAC number of a user using asp.net website. I know you can get an IP address (don't know why but it can't be complicated) but can i find out the MAC address having the IP?
Edit: I mean programmatically (not manually) in .NET
The IP address is necessary for routing the communication between the client system requesting the information and the server. You can get it, because the IP address is pulled from a lower level in the TCP/IP stack (level 3 I believe). The MAC Address isn't necessary for any of this and hence it isn't included in the communication between the client and the server.
If your site is trusted, you can do this in IE:

I wouldn't expect it to work for any typical visitors, just users who's systems you already control, like on your local network. There may be a second way in IE if you can find a common activex that generates a guid using CoCreateGuid. It returns the mac address in part of the guid. I wouldn't bet on finding one that's commonly installed though.
no chance to get this sorry.
Even if you could it would not make sense to attempt to get this, when I access a website on the internet my MAC address never leaves my home network.
Ok if the user was on the same LAN say in a company intranet for example this could be determined by having the ip address and using command line tools like arp.
ARP stands for Address Resolution Protocol and it can be used for finding a host's link layer (hardware) address when only its Internet Layer (IP) or some other Network Layer address is known.
Java 6 has a NetworkInterface#getHardwareAddress() method which usually returns the MAC address of the computer in question. You could create a small Java applet to communicate with your web server to obtain the MAC address, though there are ways and means of spoofing a MAC address.
The MAC address you get might not be practical to use. If someone has multiple network adapters then they also have multiple MAC addresses. And it's not uncommon anymore that someone has two networks. (For example, bluetooth, regular cabled and WiFi would already be three.)
A MAC address is just for identification and it can be requested. The Address Resolution Protocol is created for this purpose. By arping you can get a MAC address. Unfortunately, this only works on local networks, not on the Internet. I think that by using IPv6, you might also have a few options. Although I think it would still be limited to just a local system.
Getting the MAC address of your visitor might be considered inappropriate and perhaps even criminal since a MAC address is generally used as an unique identifier. This information could be misused by hackers, especially when the hacker manages to gain physical access to the users network. It would allow him to impersonate the user. Your site might make some security specialists very unhappy...
At http://www.ipaddresslocation.org/find-mac-address.php there's a Java applet which they claim will work. It doesn't on my system with Google Chrome, though.
I have a similar problem (I'm using the client device MAC address as a key to target different content at different devices). This thread has been useful. Given that there seems to be no way to do this implicitly I have instead included the MAC address as one of the parameters passed by the client to the web service.
(N.B. This is not a generic answer, it only makes sense where the client and server are tightly integrated and where there is scope for passing data with the call.)
I don't think this is possible on any platform.
Our flex app talks back to its originating server over a TCP-socket connection. This requires an allowance from the server in question and thus we've set up a socket policy server at the host (source code at pastie.org/791060).
This has worked fine on many permutations of Firefox, Safari, Windows and Mac OS X, but then yesterday we discovered problems with IE 7 on Windows XP. In about 50% of the cases a SecurityErrorEvent is raised upon socket.connect. This despite calling Security.loadPolicyFile("xmlsocket://:843") before connecting, and the observation of the socket policy server transmitting the socket policy data to the client (checked with tcpdump). The error can often be undone by reloading the flash app in question, while restarting IE triggers its return.
Why do we see this intermittent errors, and what can we do about them?

I've pinned the issue down to a bad socket policy server implementation. It seems like it hanged up too early in the TCP conversation with the flash client (didn't wait for the string), causing the connection errors under some circumstances, IE 7 on Windows XP notably. I didn't know that it was so easy to create havoc on the TCP level from the user level...
Heath: Thank you for your time. I will keep your hypothesis of the firewall acting up in my mind because I will surely encounter it later on as our testing progresses.
