network-interface

I need to collect all the interface names, even the ones that aren't up at the moment. Like ifconfig -a . getifaddrs() is iterating through same interface name multiple times. How can I collect all the interface names just once using getifaddrs() ? You could check which entries from getifaddrs belong to the AF_PACKET family. On my system that seems to list all interfaces: struct ifaddrs *addrs,*tmp; getifaddrs(&addrs); tmp = addrs; while (tmp) { if (tmp->ifa_addr && tmp->ifa_addr->sa_family == AF_PACKET) printf("%s\n", tmp->ifa_name); tmp = tmp->ifa_next; } freeifaddrs(addrs); getifaddrs()

I need to know how to get all network interfaces with their IPv4 address. Or just wireless and Ethernet. To get all network interfaces details I use this: foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces()) { if(ni.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 || ni.NetworkInterfaceType == NetworkInterfaceType.Ethernet) { Console.WriteLine(ni.Name); } } And to get the all hosted IPv4 addresses of the computer: IPAddress [] IPS = Dns.GetHostAddresses(Dns.GetHostName()); foreach (IPAddress ip in IPS) { if (ip.AddressFamily == AddressFamily.InterNetwork) {
