Minimum Viable Linux
summary
Shows concrete SSH tricks like using authorized_keys command to constrain keys, local and remote port forwarding and a SOCKS proxy; walks through live troubleshooting with df/du, lsof, top/htop, killing a crypto miner, and using inotifywait to reveal excessive file IO and inode exhaustion. Demonstrates strace against PHP-FPM children, inspects PHP-FPM access logs, diagnoses session file locking causing blocked requests, and explains workarounds (restart or restart process, session_write_close). Demos mostly run live; a few fail but the failures become diagnostic examples.
