I'm developing an mac app with Xamarin, im having stack overflows like this
Stack overflow in unmanaged: IP: 0x24a265, fault addr: 0xb049d4dc
Stack overflow in unmanaged: IP: 0x59b66, fault addr: 0xb049cd14
Stack overflow in unmanaged: IP: 0x24a265, fault addr: 0xb049d4dc
Stack overflow in unmanaged: IP: 0x59b66, fault addr: 0xb049cd14
im trying to figure out what "IP: 0x24a265" and "fault addr: 0xb049d4dc" means, please help to solve this I'm kind of stuck here.

I got a little confused about sockets.
In an address like:
https://localhost:5000/
...where I am running a web server during development, I know that the HTTPS translates to the local port 443, so the question is, what is the 5000 port number in that address?
HTTPS defaults to port 443, unless otherwise specified. In localhost:5000 you are explicitly specifying a port, so it's port 5000. Only https://localhost would be using port 443 implicitly.
when you request localhost:5000, the browser will go to the webserver on the localhost, but on port 5000, this means that if your webserver is setup to work on port 5000 or one of it's virtual hosts are setup to work on port 5000 you will get a response,
Read this line very carefully thrice, the browser will go to the webserver on the localhost, but on port 5000,
so , answer to the question what is the 5000 port number in that address? is that the webserver will try to find a response from port number 5000 , it will not go and find response on any other location .

I hope it makes sense to you !
Thanks !

I'm trying to setup Wireguard on a desktop at a remote location. I haven't been able to connect, unfortunately, from the client end. I'm a little new to this, so I apologize for any foolish questions.
I noticed that my computer has been given an IPv4 address and an IPv6 one based on ipv6-test.com:
IPv4: 73.57.249.195
IPv6: 2001:18c:201:f070:ed21:d822:cab2:85xx
Here is my tunnel on the server-side:
[Interface]
PrivateKey = KEY
ListenPort = 51820
Address = 10.12.34.5/32, fd43:43:43::7/128
[Peer]
PublicKey = KEY
PresharedKey = KEY
AllowedIPs = 0.0.0.0/1, 128.0.0.0/1, ::/1, 8000::/1
Here is my client config file:
[Interface]
PrivateKey = KEY
Address = 10.12.34.5/32, fd43:43:43::7/128
DNS = 8.8.8.8, 8.8.4.4
[Peer]
PublicKey = KEY
PresharedKey = KEY
AllowedIPs = 0.0.0.0/1, 128.0.0.0/1, ::/1, 8000::/1
Endpoint = 73.57.249.195:51820
I'm not exactly sure what to set the port and address to, specifically. Perhaps that is where I'm off? Any and all help would be deeply appreciated. Excited to get my first instance of WireGuard going.
Looks like both ends are trying to use the same set IPv4/v6 addresses (10.12.34.5/32, fd43:43:43::7/128) inside the tunnel.
Aside from that, assuming the keys are right and there's no firewall blocking things, it looks like it should be good, so long as the client-end initiates so the server can "learn" its externally-addressable endpoint.

I have a dlink router..Dlink DIR 600M...I am trying to port forward 1337 and 1334 through my router and opened listener but after enable i checked canyouseeme.org but theres no port opened..i have a cable net connection...my wan ip and public ip is different.
If your WAN IP address and your Public IP addresses are different, you will need to be sure that you first port forward from the public-facing router to your D-Link router. If you do not have access to your public facing router (as is the case with my current network setup), then this port forwarding is not possible.
I have a DIR-651, and there are check boxes next to all the Port Forwarding rules. Make sure those are checked. I've wasted hours of troubleshooting because one of the boxes wasn't checked and saved.
Finally, make sure that you have a server running on the correct IP address and port that you specified on your router. Also, make sure that your firewall is disabled on those ports. If your server isn't configured to respond on those ports, then canyouseeme.org will not respond that those ports are open.

I'm trying to create a multi-protocol server using Go. One server is an HTTP server, listening on 80. Another, is a custom-made protocol (over TCP) running on port 8088. Is this possible with Go?
For example:
func serveHTTP() { http.ListenAndServe(...) }
func serveCustom() { net.Listen("tcp", ...) }
go serveHTTP()
go serveCustom()

If we have soft port 80 for http,which can be connected by telnet localhost 80,
can there be an I/O(hardware) port with the same number 80?
http is TCP port 80
It has nothing to do with hardware vs software (and yes, there exist hardware implementations of TCP/IP networking).
TCP port numbers have meaning when they appear in a TCP packet header. There is no connection to other types of port numbers, e.g. I/O port numbers which are used by the inb and outb functions and (on x86 computers) appear on the address lines of the system bus (e.g. ISA or PCI). If you called inb(80), it would not mean "http" in any way. On my computer, I/O port 80 (0x50) is used by the system timer.
Note: The windows equivalent to inb is READ_PORT_UCHAR.
