The various limits and timeouts that are available to configure CompleteFTP sites are described below. Note that settings must be saved via the Apply Changes button, otherwise they will be lost.
| Setting | Description |
| Timeout for HTTP sessions | The maximum time in seconds before HTTP sessions expire. If the timeout is set to zero, sessions do not expire. The default is 1,800 seconds (30 minutes). |
| Timeout for logging in | The maximum time in seconds permitted for a login attempt. If a connection is made and login is not completed within this period, the connection is closed. If the timeout is set to zero, the timeout is infinite, i.e. the connection does not time out. |
| Timeout for stalled transfers | The maximum time in seconds that the underlying sockets wait for while performing read operations. If the timeout is set to zero, the timeout is infinite, i.e. read operations do not time out. |
| Timeout for idle sessions | The maximum time in seconds that a connection is permitted to be idle, i.e. if no commands are sent from the client. If the timeout is set to zero, the timeout is infinite, i.e. the connection does not time out. |
| Timeout for PASV wait | In passive mode, the server listens on a socket, waiting for the client to make a connection. The client can connect before actually sending the next command (LIST,NLST,RETR or STOR), and the server must wait for this next command before it can do anything with the client connection. If the timeout is set to zero, the timeout is infinite, i.e. the connection does not time out. |
| Max. allow login attempts | Sets the maximum number of login attempts that can be made for a user account. |
| Max. simultaneous connections | Sets the maximum number of simultaneous connections permitted. If this limit has been reached, any further connection attempts are denied until current connections are closed. This setting does not apply to HTTP connections. |
| Max. simultaneous HTTP connections | (Professional and Enterprise MFT only) Sets the maximum number of simultaneous HTTP connections permitted. If this limit has been reached, any further HTTP connection attempts are denied until current connections are closed. |
| Max. connections per user | Sets the maximum number of simultaneous connections permitted per user. If this limit has been reached for a user, any further connection attempts by that user are denied until current connections are closed. |
