I installed sangoma linux which is centOS. I have seen a security program that you install for ssh. It logs the ip address of everyone that tries to log into ssh and emails it to the admin. It also enables you to block logging in from those IP's. For the life of me I have only seen the program in a VPS I got one time. I need to know if anyone has a link I can go to to install this software on my Linux box. Does anyone have any ideas?
