Anyone know how to see what pid/process has modified a linux routing table (specifically on Ubuntu )? I have an interesting problem where a route that I have created has been deleted over time, but can’t figure out what. I’ve tried rtmon but seems to only show timestamps of the adds/deletes
My bad, I thought in Linux everything is a file
Well, the routes might manifest somewhere as files, but I don’t expect anyone to be able to viably parse them without commands like
iporifconfig(or know where the files even are).Some devices (like disks for example) are very straightforward to use as files, while some other special files (like USB devices) are so weird/ugly to use that everyone uses tools/libraries to access them (like libusb).
This is very off-topic, but there’s a great talk by Benno Rice that talks about this (among many others): https://youtu.be/9-IWMbJXoLM
Thank you for the info and I’ll listen to that talk
