Re: attached gateways

fd = socket(AF_INET, SOCK_RAW, IPPROTO_ICMP);

Here is what the code to read from it looks like:

struct sockaddr_in from;
socklen_t len;
char buf[8192];
int result;

result = recvfrom(fd, buf, 8192, 0, (struct sockaddr *)&from, &len);

Hope this helps, 

Thanks. It yields the same net effect, unfortunately.



Before I travel too far down this tangent (and drag you all with me), let me go back to the simple goal I'm trying to achieve:

My application simply needs to know the addresses of **all** of the routers attached to the computer's various networking interfaces.

For example, on my ibook, I have an airport connection to one router (192.168.0.250) and a cat5 connection to another router (192.168.1.250).

When I open system prefs, click "Network", and look at the TCP/IP section of Airport, I see "Router: 192.168.0.250".

When I look at the TCP/IP section for Built-in Ethernet, I see "Router: 192.168.1.250".


What is the simplest way to get that exact same information?

That's all I want.
