RE: Deny <ip address> didn't work

WOW!

I'm definitely a novice at this, but this is quite surprising ...

In my access log, I have several IP's that are requesting the same login
page thousands of times.  See examples below.

Also, none of the requests have a referer or browser in the log record.  I'm
thinking that the lack of browser indicates that a program is submitting the
request, not a person at a browser.  (Let alone the fact that there are 186k
requests in 2 hours would indicate that as well ....)

So now my question is expanding ...

Now I think my site is getting a significant amount of hacking attempts.
But as I said I'm a novice ...

Does this look like I'm being hacked?
Should I add these IP addresses to iptables?

I have installed "fail2ban", but I just left it at the default
configuration.  Do I need to start working with that?

Thanks,
Josh

Both of your rules just change the response for this IP, they don't block it
from sending requests. What does the access log say?
