Question

Is it possible to configure limits on incoming user connections?

Reasoning

With many users connecting to Titan, I would like to limit as much as possible each session so it does not remain open indefinitely, and also control the number of connections each user can make to avoid the server from being overloaded.

Answer

In Titan SFTP Server, you can configure how many times a user can connect from the same IP address, how many concurrent connections and also the idle time out value.

Steps

1. Navigate to Connections and click on the General tab.
2. You can configure the value in seconds for the idle timeout for a session. 

NOTE: This means the amount of time a session is open but is no longer performing any actions or sending any commands. These sessions will eventually timeout, but it is recommended to set the smallest time possible so the sessions time out as soon as possible releasing the occupied port, memory and CPU resources.

3. You can configure the “Max Concurrent Connections”:

NOTE: The concurrent connections refer to the number of sessions a single user account can have at the same time. If set to “1”, if UserA connects a second time while the first session is still open, the second connection will be refused until the first session is closed.

4. You can configure the “Max Connection/IP”:

NOTE: The Max Connection/IP refer to the number of sessions allowed from the same IP address(regardless of username). If set to “1”, if UserA connects from one IP address and UserB connects from the same IP address while the first session is still open, the second connection will be refused until the first session is closed.

5. You can configure the Max Uploads/Session:

6. You can configure the Max Downloads/Session:
