The best thing to do here is to kill your ident server, or add a firewall entry for port 113. Even better, you may wish to create an obfuscated or common username for regular use. Something like bob, jane, Acidburn, or ZeroCool, perhaps ;) [root@machine ~dir]# iptables -A INPUT -p tcp --dport ident -j DROP FTP Logins Be aware that your FTP client may also transmit your username or email address as the anonymous password independent of your ident response.
