Re: some ftpd problems

[Jon Adam <jonadam knowhownet net>]

Are you usig a router of any kind?  I had this same problem and I noticed
slow logins and such.  I put in a new router and it helped some, I use
port forwarding through the router.  I also replaced the ethernet card and
I quit having the problem.  If you have firewall setup on your machine, it
may be one of the settings.

Hope this helps some.
