comment Does the suid bit have any meaning for device files?
You don't execute a device file so it won't have any effect.

comment Confusing my IP stack
What's the subnet of all these interfaces (are they all really /16 or 255.255.0.0?) What's the "entirely different subnet" you are pinging from? If this is a Linux system, the output if ip addr show would be helpful. It sounds like there is a problem with the subnet addresses assigned off the top of my head.

comment What is kernel ip forwarding?
Your NIC can actually receive all traffic on the subnet by design - if you have it connected to a hub, not a switch. It won't forward it out of the default gateway since it has a direct connection to that network 192.168.2.0/24 already. So I believe it will drop it.

comment Difference between /bin and /usr/bin
Makes sense because /bin/false is used to prevent an account from obtaining a shell on login. You need to change /etc/passwd from a different account or a rescue boot.

comment How can I kill a process and be sure the PID hasn't been reused
Use killall which matches on name, so at least you are only killing a process with the same name as longrunningthing. Assuming you will only have one of these running at a time.

comment Cannot login for one user, changing password have no effect
Is /usr/bin/bash a symlink to /bin/bash? It may not work if it's a symlink.

comment Difference between /bin and /usr/bin
No, it's mounted at boot and stays mounted unless you unmount it, unless your system is configured unusually.
