On linux, I'm used to typing
ifconfig and looking for the line with "RX bytes" and "TX bytes" in it to find out how many bytes have been received and transmitted over a particular interface since boot. The line looks like this:
RX bytes:106951129 (101.9 MB) TX bytes:1577761831 (1.4 GB)
I tried running the same command in a terminal on a Mac (OS X, version 10.4.11) but didn't see this data anywhere. How do I get the same information from a Mac?
Edit: This is a test server, meant to simulate a typical out-of-the-box Mac install. So I need to avoid installing any programs if I can. A command-line tool would be ideal.
