It’s Official

I think I’m officially a geek now. I got my first black computer. 😉 It has a multicolored blinking lights on the inside and everything.

… then again its just some (really nice assuming everything works) old junker that a family member was getting rid of and not one I built myself. :\

Oh well. I’ll swap out a drive or something and take all the credit. (That’s just as good, right? :-P)

... more like this ...

So that’s what a brute force attack on an SSH server looks like! 😉

Fortunately, I took time to read and secure the SSH as best I know how and no damage appears to be done. (If the output of less can be trusted) There were only two real attacks.

All in all I learned from the whole thing. I should probably start getting into the habit of reading my logs, and I learned a couple of user names not to use. (my favorites being fluffy, gopher, and Zmeu) I think I also want to look for an ipchains rule to limit access to only IP addresses in my state.
