I have just concluded a post-mortem on one of my servers.
Cause of death: out of memory due to a tiny memory leak in a VPN service triggered by 66 different IPs brute-forcing the creds at the same time. Mostly from China, of course.

Dear bot writers: you made me put aside my spaghetti and write iptables rules. I hate iptables. And I love spaghetti. You should be ashamed of yourself! Did momma not teach you basic OpSec? Don't crash the target and never, ever, interrupt the sysadmin during dinner!

    Wow, it does sound like that. Did not see that. 😂
    Although, to be fair, the iptables rules on that server are the equivalent of spaghetti code. Some from UFW, some manual and some from an old script, written by someone I haven't heard from in years 😅

    No one interrupts sysadmin with spaghetti! Bots can be very frustrating. IP tables though?
