How to enable telnet with port 3306 during Master to master replication on MySQL Server
- by Mainio
I am trying to do Master to Master Replication in Windows Server 2008. I am successfully able to replicate all the database of Master 1 to Master 2. But I am unable to replicate the changes made on Master 2 to Master 1. Later on I found that, I can telnet to Master 1 from Master 2 with port 3306 but I am not able on telnet from Master 1 to Master 2. 
When I check netstat on both Master. I found the following result. I couldn't publish my public IP so I put name as Master 1 and Master 2 for their respective IP
Master 1
C:\Users\XXXXX>netstat
Active Connections
  Proto  Local Address          Foreign Address        State
  TCP    Master 1:3306          Master 2:61566      ESTABLISHED
  TCP    Master 1:3389          My remote:56053     ESTABLISHED
  TCP    127.0.0.1:3306         Master 1:60675      ESTABLISHED
  TCP    127.0.0.1:3306         Master 1:60712      ESTABLISHED
  TCP    127.0.0.1:60675        Master 1:3306       ESTABLISHED
  TCP    127.0.0.1:60712        Master 1:3306       ESTABLISHED
Master 2
C:\Users\XXXX>netstat
Active Connections
  Proto  Local Address          Foreign Address        State
  TCP    Master 2:3389        My remote:56124     ESTABLISHED
  TCP    Master 2:61566       Master 1:3306       ESTABLISHED
  TCP    Master 2:61574       bil-sc-cm02:http    ESTABLISHED
  TCP    127.0.0.1:3306       Master 2:61562      ESTABLISHED
  TCP    127.0.0.1:3306       Master 2:61563      ESTABLISHED
  TCP    127.0.0.1:61562      Master 2:3306       ESTABLISHED
  TCP    127.0.0.1:61563      Master 2:3306       ESTABLISHED
  TCP    127.0.0.1:61573      Master 2:3306       TIME_WAIT
All shows that In my master 2, port 3306 is not activate. Now I need solution over here. How can I figure it. Your small suggestion would be million for me.
Thank you
