/proc in Linux

Posted on 2022-03-252023-01-06 by lechuck park

I love /proc directory. because you can find almost work inside a Linux Operating system.

nubmer is process_id -> in that directory, you can check process status.
ex) How many files opened in specific process (with process-id) ? ‘fd’
ex) memory usage detailed ‘mem’ and…

Too many, so find it by yourself via googling 🙂

DNS (TCP/UDP port 53) Packet also can be good for this concept of monitoring. ( if you can’t capture all raw packet. )
