I was trying nmap command on my server. and i have seen that my ip has been blocked.
I can access the server from other computer.
How can unblock my ip in centos
First of all i would check to see if you have iptables running
You can wipe out all the iptables rules by going
Lastly could you please give a bit more information on what you are trying to do and what ports you are trying to connect to and also is this a internal IP or an External IP you are trying to connect to? at the moment this question seems a little vague so difficult to help you with.
