Can access mysql server via command line utility but not via rails

I've been successfully read and writing to a MySQL database on one
server from my RAILS application on another server for almost a year.
For various reasons that I aren't important I tried to switch to
another database server. I can access, read and write to that
database server from my application server via the mysql command, but
when I attempt to load the console it takes a really, really long time
to load the console. Then when I try to read the first record of an
arbitrary model the console hangs again for a really, really long time
and comes back with this message:

Mysql::Error: Can't connect to MySQL server on '72.32.121.29' (110)

I'm really confused why the servers can talk via the mysql command and
not via the rails app. Any help would be appreciated.

Never mind! It was a hosts file issue. All better now.
