    From two days ago. I type in ssh tail -f /var/log/messages and all time have a ip traying to access at ftp how administrator. This is a example from today:

    Mar 18 11:49:19 server pure-ftpd[56108]: (?@60.217.229.228) [WARNING] Authentica tion failed for user [administrator]
    Mar 18 11:49:40 server pure-ftpd[56108]: (?@60.217.229.228) [ERROR] Too many aut hentication failures
    Mar 18 11:49:46 server pure-ftpd[56419]: (?@60.217.229.228) [WARNING] Authentica tion failed for user [administrator]
    Mar 18 11:50:21 server last message repeated 3 times
    Mar 18 11:50:39 server pure-ftpd[56419]: (?@60.217.229.228) [WARNING] Authentica tion failed for user [administrator]
    Mar 18 11:50:59 server pure-ftpd[56419]: (?@60.217.229.228) [ERROR] Too many aut hentication failures
    Mar 18 11:51:06 server pure-ftpd[56479]: (?@60.217.229.228) [WARNING] Authentica tion failed for user [administrator]
    Mar 18 11:51:26 server last message repeated 2 times
    Mar 18 11:51:30 server su: usuario to root on /dev/ttyp0
    Mar 18 11:51:41 server pure-ftpd[56479]: (?@60.217.229.228) [WARNING] Authentica tion failed for user [administrator]

    I have enabled in cpanel security brute force. I cannĀ“t undestand bacause not work with this ip.

    Can I do anything?

    install CSF.

    It'll automatically block these using LFD

    Code:
    wget http://configserver.com/free/csf.tgz
    Once done, just run the installer and configure :)

    I know this is an old thread, but I had a similar issue...

    I am running FreeBSD and wanted a solution to the brute force attacks. I found sshguard (Sshguard) does the trick nicely, and is in the ports tree (/usr/ports/seurity/sshguard). Install the version for your firewall (pf, ipfilter, or ipfw).
