Remove ip from hosts.deny

This worked for me on Centos. Follow the 8 steps below and you should be good to go.

Stop DenyHosts

# services denyhosts stop

Remove the IP address from /etc/hosts.deny

Edit /var/lib/denyhosts/hosts and remove the lines containing the IP address. Save the file.

Edit /var/lib/denyhosts/hosts-restricted and remove the lines containing the IP address. Save the file.

Edit /var/lib/denyhosts/hosts-root and remove the lines containing the IP address. Save the file.

Edit /var/lib/denyhosts/hosts-valid and remove the lines containing the IP address. Save the file.

Edit /var/lib/denyhosts/users-hosts and remove the lines containing the IP address. Save the file.

(optional) Consider adding the IP address to /var/lib/denyhosts/allowed-hosts

Start DenyHosts

# services denyhosts start
