mysql over ssh over 非标准端口

Question

I am on computer A, and have mysql running on it, and can connect to it as A~ $ mysql -u punkish -p database and so on.

I have access to computer B that also has mysql running on it. I can ssh into B over port 2200 with ssh key pairs set up, and once in, I can connect to the db like so

A~ $ ssh -p 2200 punkish@B
B~ $ mysql -u punkish -p database

However, I want to set up port forwarding over ssh on my computer so all requests made for mysql on port 3307 on my computer A are actually sent to port 3306 on B. This will allow me to use a gui program that wants to connect to mysql, but can't do it over a tunnel. So, I do the following

A~ $ ssh -p 2200 -L 3307:B:3306 punkish@B
B~ $

The above logs me right into B. I am not sure if the tunnel is established, but I am assuming it is. However, the following fails (in another terminal

A~ $ mysql -P 3307 -u punkish -p
Enter password:
ERROR 1045 (28000): Access denied for user 'punkish'@'localhost' (using password: YES)

Here is the interesting thing -- I have another gui program called Sequel Pro (a desktop MySQL client for Mac OS X), and that is able to make a connection to mysql@B over ssh just fine. So, I know something works... I just don't know how, so I may be able to enable it for another gui program.

mysql usually attempts to use a socket file if you don't specify a hostname. So as part of your mysql command, specify -h 127.0.0.1 (notice I did NOT say localhost, it treats them differently). This basically forces a TCP connection instead of the socket file connection.
