managing bandwidth

[mandreko]

i have an ftp server on my gateway, and if someone logs in, they can take all my bandwidth, leaving the computers behind the gateway almost without internet... is there a way to limit proftp to a certain speed? like say they can download at 50k/sec?

1.2.0 or later
ALWAYS use CVS version of proftpd, btw.
