Connection between a cross cable + MySQL Backup

I need to connect from Server B to Server A by MySQL.
The Servers are connected by a crosscable.

Server A: PRODUCTION SERVER
===========================
IP 192.168.0.100

ISPCONFIG INSTALLED


Server B: BACKUP SERVER
=======================
IP 192.168.0.101

At the moment there is a NAT Rule installed in the Server A in order to share the internet connection.

How can I connect to my Server A (Production Server) from the Server B using MySQL?

If I execute a telnet connection I get this error:

Code:

# telnet 192.168.0.100 3306
Trying 192.168.0.100...
telnet: connect to address 192.168.0.100: Connection refused
telnet: Unable to connect to remote host: Connection refused

Thanks

 

What's the output of

Code:

netstat -tap | grep mysql

on server A?

 

# netstat -tap | grep mysql
tcp 0 0 server1.mydomain:mysql *:* LISTEN 21392/mysqld

thanks

 

can the servers see eachother?

try to ping the servers from each other.

ping 192.168.0.100

you can end this with ctrl c

do you get a similar result

64 bytes from 192.168.0.100: icmp_seq=1 ttl=64 time=0.242 ms

 

Solved.
The problem was the bind configuration inside the my.cnf.

I have commented it and I have created a new root user with the local ip permission in this way:

Code:

mysql> CREATE USER 'root'@'192.168.0.101' IDENTIFIED BY 'password';
mysql> GRANT ALL ON mysql.* TO root@'192.168.0.101' IDENTIFIED BY 'password';

thank you in any case!
