Here are my FTP logs (Pureftpd as you can see)
Code:
Aug 23 18:22:12 monster pure-ftpd: (?@RemoteIP) [INFO] New connection from RemoteIP
Aug 23 18:22:13 monster pure-ftpd: (?@RemoteIP) [INFO] Logout - CPU time spent: 0.050 seconds.
How the RemoteIP could establish a new connection to my server and then log out?
