Ethernet Port device path?
Hi,

I have a server program that reads data coming in on USB ports. Device paths are in the format: /dev/ttyUSB0

Now, I would like to log data from another device coming in over Ethernet. My first step is trying to track down what the correct device path is which I am unsure of.

Anyone know?

Thanks!

Ethernet devices are not found in /dev, they do not have corresponding device files.

Ah okay makes sense.
Where would I look for them?

You don't. They don't exist. You'll have to write a C program if you want raw access. (darkstat may be useful at showing how to capture all traffic on an ethernet interface.)

helpful.

I just need to find some sample code on how to establish a connection via TCP/IP on port 22223. I am assuming that this isn't too hard. I will post if I find info.
