How to block the IP after many times fail login?
Hi, there. I am using Red Hat 9 to run my web server. Recently I found lots tempts from different IP addresses tried to login into my system. I am not sure if they are the same person or not. Since this server is only for web hosting purpose for couple of my friends and myself, so it is very easy found out other people tried to get in.
My situation is like this: I have to run the ssh, but those tempts are really annoying. So could anyone show me how to block an IP address after 5 fail login, just for couple hours.
Thanks in advance,
HOUSCOUS
