      I suspect that you may be unaware of the meaning that phrase has elsewhere lol

        Wow. That's just sad. Guess I'll be expecting a visit from the FBI or NSA in a bit.

        K-LINE is an old school IRC terminology. Was helping my old man with his IRC server today, lol.

        K-LINE = block it forever... (on a Linux box, just use iptables, it's far, far easier).

          I'd just K-Line the whole /16 subnet and be done with it and see if that slows it down.

          That's what I've been doing with cphulk. The number of different systems being used is a little crazy. At this point I'm just wondering if I'll ever be able to prove anything, even tho I'm almost certain it's a government agency behind it.

          Example of cPHulk email:
          alt text

          Block the IANA Netblock and call it done.

            @Ambarishrh I saw that, doesn't really give me anything beyond what cPHulk is doing already. Might have to try it on some local systems tho.

            cPHulk uses a MySQL database that does not use iptables in the manner CSF is using. It is more intensive to block using cPHulk due to the fact it blocks based on logging authentications to a MySQL database and then determining actions based on it. It is actually more streamlined and easier to manage CSF / LFD due to it dealing directly with iptables via flat files.

              I grep that. I have been keeping an eye on performance, and we haven't seen any detrimental effects yet (the memory cache for the mysql instance is ~2x the db size currently.)

                    Got this knocked down to one every half hour instead of once every five minutes by 5PM yesterday, and the last notification I got was at 6:02AM this morning, hopefully we're done with these..... silly.... people.

                    Some (hopefully) final numbers for you all.

                    They never even tried a valid user in addition to trying this on a service that responds as being active but then rejects all login attempts. Silly, silly people.

                    PS - I hope all the mods appreciate my self-moderation here 😉

                      @travisdh1 I'm totally shocked... not a single hit for root as the login name!

                        I know right 😕

                        When I first started here, the website was hosted on a Windows Server VPS, so the administrator at least makes a little sense.

                        Also, remote root login (the only one available because it's a VPS) is key based. So go ahead and try logging in as root with a password.

                          Ha we can't log in with root at all over SSH.

                            While it's very tempting to do just that, the only user the system started with was root. If I have to burn it all down, I need some way to access the thing.

                                I do, but the only user on the system was created after the OS/cPanel was installed. So if I have to nuke it from orbit, I kinda need that access.
