I really think you should have a read through the rest of this thread to get a handle on what level Richard is at with his use of Debian. What I'm trying to say is that I really doubt that a very terse message about udev rules is going to be at all usable for Richard. Furthermore, what you would then find is that Richard's network device changes MAC address at every power cycle, so even if Richard did decide that this was the way to go and was able to make a start on it, your suggestion wouldn't actually work for him. No doubt a udev rule *can* be crafted that works in Richard's case to give his network device a stable name, but it's going to be a bit more complicated than what you have posted here. But most importantly, nowhere in this thread has it actually been shown that the fact that Richard's network device changes name (due to it changing MAC address) is any barrier to his intended use of vnstat. Others have shown that vnstat can aggregate traffic from all interfaces, and this is the only network device that Richard has in use. So this may be a rabbit hole that does not need to be gone down, and past experience suggests that a lot of people could spend a lot of time trying to explain to Richard how to write udev rules for no practical benefit. Unless of course Richard decides that he wants to learn about udev rules just for the sake of it. I appreciate that you are just trying to give a solution to the stated problem that you are replying to, but in this case the rest of the thread has established that this isn't really a problem for Richard's end goal (monthly traffic stats with vnstat) Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
