FTP question

[Francis X. Maier]

The fog still lays heavily on my head re the whole website-on-my-Linux
box thing, folks.  Last week, thanks to this list, I managed to get
Apache up and running.  But now I'd like to access my website via FTP
from the office to update the site.

So I checked the YDL HOWTOs and found something on proftpd, which I then
discovered seems to be an alternative to vsftpd, already on my machine.
So I went in and turned on vsftpd; but I still can't upload -- wrong
login, etc..  Is there some other step I need to take?  Thanks in
advance!
