The Users tab becomes available in the right configuration panel when Activity is selected in the left tree panel. When active the Activity Menu appears in the menu bar.
This configuration tab consists of the list of currently connected users and an Auto reload option. From this list you can see each of the currently connected users, their IP address, what the user is doing, the user’s current directory, and the user’s last command issued. For Windows NT/XP/2000/2003 there is another way to see what is happening on the server: By using the Windows Performance Monitor program.
When a user is connected through secure-FTP a small padlock is shown with the activity icon, indicating the session or file transfer is encrypted.
When Auto reload is selected the current user list is automatically updated.
When a user is selected you can use the menu or toolbar to disconnect the user or send a message to him. Killing a user brings up a dialog box with a number of choices:
Kick user
This option simply disconnects the user without doing anything else. Any ongoing data transfers are cut off, the effect is immediate.
Kick user and block IP XX minutes
This option disconnects the user and places the user’s IP address on the list of blocked IPs and will prevent the user from connecting again for a number of minutes.
Kick user and ban IP xxx.yyy.qqq.zzz
This option disconnects the user and places the user’s IP address on the list of banned IPs of the user account. With the IP being banned the user will not be able to log in again from banned the IP address. The IP address can be edited before and allows for wildcard characters such as ‘*’ and ‘?’. Using the Subnet button will automatically calculate the proper IP address to block all access from the IP-subnet the address belongs to (An IP subnet is usually owned by one entity, like an Internet Service Provider).
Kick user and disable account
This option disconnects the user and disables the user's account. The effect is that no other FTP users can log in to this account until it has been enabled again.
Message to user
Type an optional message here to inform the user of his disconnection. Serv-U will try to send this to the user before disconnecting, but not all FTP clients support messages so the user may never see the message.
