mysql replication through ssh reverse tunnel

well, connecting to a mysql db through a reverse tunnel was easy. on the host machine (in this case, my ircbot's vm) do something like: 
$ ssh -nNT -R 3307:localhost:3306 remote@machine
now on the remote machine, i can test it is working by logging into mysql at that port: 
$ mysql -h localhost -P 3307 -u root -p
all is well—or so i thought. after configuring mysql to be a replication master in typical fashion, i enabled binlogs, set the binlog databases and gave it a server-id. something like this was added to the mysqld section of my my.cnf: 
log-bin

binlog-do-db = awesome
binlog-do-db = awesomest

binlog-ignore-db = mysql
binlog-ignore-db = test

server-id   = 1
gave mysqld a restart. then i added a replication user - note the @'%' 
mysql> grant replication slave on *.* to 'repuser'@'%' identified by 'awesomepassword';
last thing to do was just make a dump of my databases. since they're small, i can do this. 
$ mysqldump --databases --add-drop-database awesome awesomest >awesome_dump.sql
i copied awesome_dump.sql to the slave machine. i shut down mysqld first and changed the server-id in the my.cnf 
server-id   = 2
then i started up mysql and dumped the databases into it 
$ sudo /etc/rc.d/mysqld start
$ mysql -uroot -p <awesome_dump.sql
then i had to actually start replication in mysql 
mysql> change master to 
    -> MASTER_HOST='localhost', 
    -> MASTER_PORT=3307, 
    -> MASTER_USER='repuser', 
    -> MASTER_PASSWORD='awesomepassword', 
    -> MASTER_LOG_FILE='ircbot-bin.000002', 
    -> MASTER_LOG_POS=106;
Query OK, 0 rows affected (0.01 sec)
mysql> slave start;
Query OK, 0 rows affected (0.01 sec)
then i check show slave status to make sure everything was okay 
error connecting to master 'repuser@localhost:3307'
fml. when i first set this up, i created my replication user as 'repuser'@'%'. normally that is fine, but in the default installation of mysql on arch linux, there are anonymous users. so logging in as 'repuser'@'localhost', it actually logged me in as ''@'localhost' instead of 'repl'. joy. there are two ways to fix this: i did both. all is well again in the land of nool.
