- Socat - Create a listening service that forwards to a service inside a network namespace (socat is amazing):
/usr/bin/socat UNIX-LISTEN:/run/transmission.sock,fork exec:'ip netns exec NETNS socat STDIO tcp-connect\:127.0.0.1\:8080',nofork
- HTTP Client -> [Unix Socket Server] ---- | Network Namespace Barrier | ----> HTTP Server (localhost listening)
- strace -p PID - Look at calls between the process and the kernel
- gdb, python-dbg - Look at stack traces live

(ALL:ALL) is (user-we-can-command-as:group-we-can-command-as), i.e. sudo -u user -g group. If omitted only root. Can use just (ALL)
NOPASSWD: is tags
command may be "ALL".
"" prevents command parameters.

How to apologise(!). Source
- An expression of regret, i.e. "I'm sorry"
- An explanation (but not a justification)
- An acknowledgement of responsibility (most important)
- A declaration of repentance
- An offer of repair
- A request for forgiveness (least importance)
Don't say: "IF", "I regret", Don't use passive voice. Say how you're going to make sure this doesn't happen again.
