    Good Day,

    Running ISPConfig 3.0.5.4p3 on CentOS6.5.

    I have a customer working from Thailand and I am in Canada. I guess he gets quite a few bad or cut connections. He has let me know that he can only do 4 or 8 FTP connections to the server with FileZilla. How could I bring this limit to, say 15. I believe FileZilla can go up to 10 connections.

    Response: 421 Too many connections (8) from this IP
    Error : Could not connect to server
    Status : Delaying connection for 5 seconds due to previously failed connection attempt...
    Status : Connecting to <IP>:21
    Status : Connection established, waiting for welcome message...
    Response: 421 Too many connections (8) from this IP
    Error : Could not connect to server
    ...
    Error : Connection timed out
    Error : File transfer failed

    Is this a pureFTP setting? Is this a per-user limit? Do I need to do something with fail2ban?

    Thank you ahead once again,

    Thats a global setting in pure-ftpd. Take a look at pure-ftpd.conf file, ther should be a setting like:

    MaxClientsPerIP 8

    or similar were you can change this. fail2ban has not to be altered.
