Default Where to set max login for Proftpd?

I've noticed some "undesirables" trying to login to my ISP machine via FTP, and after 3 attempts him (or her?) gets locked out.
Question:
1) How long does it block the same IP from re-attempts? Can it be set?
2) Is there a way to add failed login attempt IP's to the firewall automatically?
3) Where can I set # login attempts for proftpd - seems to be somewhere in other database or config files?

Thanks

PS. I now have successfully got ISPConfig on perfect Hardy Heron working, with about 5 web sites with external DNS names. I've retired my IIS server and put Linux online. Not bad for a newbie lol... only took me 3 weeks
All this thanks mostly from help in this forum...keep up the good work guys.

Is it possible that you're using fail2ban, DenyHosts, or Blockhosts and have locked out yourself?

It's not myself that is the issue, everything is working fine, including proftpd. I can also ftp from the outside world just fine

What I was referring to was that outside "hackers" were trying to FTP to my site, and tried to log in 3 times before the system (proftpd) did a "locked out" for that attempt. I do NOT allow any anonymous FTP. I wanted more detail on where those lock out parameters are set. Proftpd is behaving properly, and that user was unwanted, I just wanted the details of the Proftpd settings, and how ISPConfig controls it (if at all)

I wanted to know where this "lock out" attempts is set. Currently my system is just the "Pefect server Ubuntu 8.04" with ISPConfig and 5 web sites, nothing else added except ddclient and phpBB3...

I keep an active eye on hacking attempts. My "real" firewall is a Mikrotik router at the WAN side, nothing on the "Perfect Server", though I would entertain the though of adding firewall rules to iptables or something (but Mikrotik router has hundreds of rules already...)

So, the basic question is: where/how can I review/modify the behaviour of Proftpd, in particular the login attempts and lockouts (like setting it to 2 instead of 3, and setting lockout time to a long time)

Steve

PS, I did find the parameter for Maxloginattempts in the Proftpd website (default is 3) that goes into proftpd.conf:
http://www.proftpd.org/docs/directiv...nAttempts.html

But no info yet on how to control the "lockout" period.
