I just implemented the abusive ip fix. Hopefully this should fix it. Now that I recall, I did this the very first time I set up the server and it ran fine for a loooooooong time. So long that I forgot to take that step again!
I use your code on www.geek.vn than switch to hackerstreet.in code. It is mostly similar but /whoami only. Your ARC code tunrs to 127 :-), not real IP.
Hackerstreet code helps me solve that tiny issue and also adds an "ask" tab on the top bar. I wonder how to add another one such as "blog" (so click on with access geek.vn/blog or about/contact etc...:-( Any help @akkartik. I am just an actual non-geek/coder :-)
I just want to add a link on the top bar, like a "news" tab, then the visitor click on that it will turn to http://blog.geek.vn subdomain. Anyways, the previous threat submitted by jwk is so helpful to me.
I just tried it behind apache, and the fix is still in working condition. Can you check if you made an error in adding it?
Is your codebase someplace public? Feel free to email it to me (address in profile). Or paste in that section of your srv.arc into a comment here to get some more eyes on it.
