I have two servers. Let's call them A and B. Both are running ubuntu server 14.04. B runs percona server. Now I do not have any firewall set-up on either servers still I am unable to connect to server B from A. Percona server is bound to XXX.XXX.XXX.XXX
When I do a
telnet XXX.XXX.XXX.XXX 3306 - where the IP is a local private IP
from A, I am unable to access it. Whereas, the server B also runs a SSH and when I try to do:
telnet XXX.XXX.XXX.XXX 22
I am able to connect. Can some tell me why is this happening?
