proFTP not blocking

[dvk01]

I am getting attacks via FTP but CFS doesn't seem to be blocking them or adding them to firewall block and I have to do it manually, when I see the hourly reports

they only seem to try 1 account at a time and ONLY 1 attempt at that account , but the same IP number tries numerous different accounts. I can't see any way in CFS settings to block IPs that attempt to log in to different accounts, only settings for how many times the same account is attempted

The proftpd regex in lfd catches those lines, so it would suggest that you have not configured FTPD_LOG correctly in csf.conf and then restarted lfd.

thanks
I have changed the log location to /var/log/secure instead of /var/log/messages and lets see if that does it

it has always been set to messages and that has informed me of any FTP log ins whether legitimate or a problem. I suppose it is due to my recent server move or the update to CP 36.x that has caused the problem

I will see how it goes
Thanks
