I use FileZilla, and I thought when a session ended, it automatically closed the ftp connection, but that doesn't appear to have happened because now I'm getting a "530 Sorry, the maximum number of connections (10) for your host are already connected." error. Is there a way to find any open ftp connections and close them from my end? Or, do I have to contact the host?

Probably the other clients connect from the same IP. Also, if you want to close a connection, you can always use tcpdrop(1):
$ tcpdrop myhost.net:2353 example.com:ftp
On Linux, and most Unixen IIRC, there is the netstat utility. By itself, it will show you what active connections there are. For example:
$ netstat Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 foo.example.com:uuidgen nfs1.example.com:nfs ESTABLISHED tcp 0 0 foo.example.com:ssh bar.example.com:54993 ESTABLISHED Active UNIX domain sockets (w/o servers) Proto RefCnt Flags Type State I-Node Path unix 2 [ ] DGRAM 88654 @/com/ubuntu/upstart ans do forth.
- You can close it if you have access to a router using in this connection data transport.
- You can change FileZilla to other program.
- You can disconnect connections from ftp administration.
- You can kill process handling that connections.
