[gentoo-user] ftp server software which supports a control connection?

Hello. I am looking for an FTP server software that let me monitor the
ftp activities on my notebook. Both server and the notebook runs Gentoo
Linux except the server doesn't have any X11 related stuff. The reason I
want to do this is because I offer my users file to download and I often
need to monitor what they are doing to make sure they gets connected.
This is especially useful when doing support on the phone, I can call my
user and instruct him to download file, at the meantime see he logged in
and doing the right thing.

I used pure-ftpd and pureadmin (a GUI for monitoring pure-ftpd).
Pureadmin has every feature I need (see who is logged in, see
activities) but it has to be run AFAIK on the same computer that runs
ftp server.

I used filezilla server which let me control it through a control
connection and see activities, but the server software doesn't have a
Linux version.

I used pro-ftpd and didn't see the option for it's GUI manager to
connect to a remote server.

What software in Linux world can do this?

As I am monitoring ftp through a wireless LAN which max at 300KB/s,
running X11-forwarding is not comfortable. running a desktop session on
the server and run vnc seems overkill.

Thanks for hints in advance!

Best regards
