proftpd message and mysql both on port21?

[mazdaracer]

In my root mail msg I see the following, which explains why I can't get
ftp going.



 --------------------- proftpd-messages Begin ------------------------ 

**Unmatched Entries**

already i
n use 
rotor.byerlyelectric.com - Check the ServerType directive to ensure you

igured correctly.




How do I read this part? Is mysql listening on port 21? Next question is
why if this is a normal ftp port? And how do 'unlisten'?
