没有办法，因为在网络层就是不通的。 除非你在 B 上安装 sylyog, 并且你能通过什么工具比如 (remote desktop)之类的连上去它的图型界面。
搞定了。sqlyog的帮助文档有说。 To understand the setup better, let us connect to a MySQL server using a real life example.E.g. Your website is hosted on 234.56.65.78. This server also has SSH server running and listening on port 22. Your MySQL server is located on server 234.56.65.79. This machine only allows connection from localhost or machine within the same network (e.g. 234.56.65.78). You publish your website on 234.56.65.78 using the username and password provided by your ISP. Ex. the username and password provided is ssh_user and ssh_pwd respectively.In this particular case you have to put in the following value for various options:Server Tab MySQL Host Address localhost Username Your mysql user name.
Password Your mysql password.
Database The database that you want to connect to. You can leave this field blank.
Port The port MySQL is listening. By default it is 3306.
Tunnel Tab Username ssh_user
Password ssh_pwd SSH Host 234.56.65.78 SSH Port 22 Local Port Any port that is unused on your local machine. If you don't have a MySQL running on your machine then you can provide 3306.
