DenyHosts and Fail2Ban do the same thing, with the later able to protect other applications other than SSH from bruteforce dictionary attacks by limiting connection attempts. Fail2Ban uses IPTables, DenyHost uses hosts.deny. So, you should use one or the other. You can also use pure IPTables with Port Knocking as another option.
