I know net = [net is just a quick hack which could easily fail under some peculiar circumstances but hey no one is complaining, at least not yet. The filter is designed with some of the answers about what counts as 'local traffic', I know it does not encompass some edge cases such as double NAT configurations, etc., but I would like to see suggestions about this. NSString *hostType = inYesOutNo ? : *host = nil įor (NSString *hostComponent in ) Many documentations and tutorials on libpcap is fairly thorough and clear, I suggest every one interested in this solution to look at those with relatively little google-fu effort.Īlso it may interest a few that my filter for internet traffic is simply the following - (NSString *)_internetFilterStringForInterface:(AKNetworkInterface *)interface Of course there are some downsides, which includes it requires elevated privileges and must capture all filtered packets to calculate statistics, but at least it works perfectly well. The final working solution I have is to use libpcap to achieve this. Of course, you'll find that many SOHO routers don't support SNMP, and those that do probably don't have it turned on. Then you can ask the router for traffic counts on that interface. Alternate Approach: SNMPįinally, if you can't use a firewall rule (as that'd require root), you could hope that the default gateway responds to SNMP community public, explore all its interfaces, and find the one with a off-subnet IP address, and then assume that is the Internet link.

At least with Linux iptables you can, and I'm pretty sure BSD pf, and probably Mac OS X. You can probably create a firewall rule to count either of those.

the destination IP address is not within the subnet of the network interface the default route goes out.

the destination IP address is not the default gateway's IP address.

the destination MAC address is the default gateway's MAC address and.

In a simple network setup, you can probably make some assumptions, and get a close enough answer by counting traffic as non-local if: This probably applies to the vast majority of home networks, and many small business ones as well. If the network is very simple, with there being only one internal subnet, only one router, and all traffic not to that internal subnet being Internet traffic, you can cheat and solve this. Traffic inside your organization can easily travel over an Internet VPN.

Sometimes, for example, what appears to be a local machine on your Ethernet segment is actually over a VPN, over the Internet (this isn't crazy, it's very useful for when remote users need to use various Windows services). Requires in-depth knowledge of the network to figure if a destination is going to be local or not-and, with things like VPNs, that may vary over time.įinally, "Internet traffic" isn't the opposite of any of those. This is a reasonable meaning depending on how your network is set up (e.g., maybe you have fast fiber between your locations, but your Internet connections are much slower, or charged per-GB). You need network knowledge to distinguish local from non-local traffic with this definition.Īnother meaning would be "IP traffic destined to machines in my organization".

E.g., at my office we have several subnets in use, with routers between them, but traffic from one subnet to the other is still clearly local. This probably isn't want anyone means when they say "local traffic".Īnother meaning would be "IP traffic destined to machines in this (physical) location".

The easiest way to count this is going to be either the routing table (if Mac OS X counts traffic stats per route, the routes on the various gateways will give you non-local traffic) or with a firewall rule. That'd be traffic that has a destination address inside the local subnet. The next easiest meaning would be "IP traffic destined to machines on the same subnet". This is one thing that people mean when they say local (and what I was thinking of when I answered). The easiest meaning of "local traffic" is traffic that does not leave the machine its generated on (two programs on the same machine talking to each other, for example). Answering you comment about which interfaces carry local traffic is actually complicated, because it depends on what you mean by local traffic.
