Hi,
I'm trying to figure how I can programatically get the the IP addresses of all interfaces. That is, I'm in a Linux machine, and I want a C program to find out the IP adderess that the machine has (like I can get with /sbin/ifconfig). One way I'm aware of, is to parse /proc/net/if_inet6, but this seems to be connected to IPv6, I want to support also IPv4. What other ways exists to find this info ?
thanks in advance,
Megatron

Hi
Does anyone know how to get the Mac address of a remote PC, using C#? I
believe it's possible by deconstructing the packet received from a ping
but I don't know how to do it.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
