## 24.3 Active Connections

In the Status → Active Connections section you can view all network connections established with Kerio MailServer including all its services (SMTP, POP3, etc.) and the Administration Console.

### Active Connections

Each line of this tab contains information about one connection. These are network connections, not user connections (each client program can establish more than one connection at one time in order to receive or send more messages at once). The columns contain the following information:

Figure 24.3. Active Connections

Protocol

  The protocol type that the client is using (or service to which it is connected). Names correspond with the names of services in the Configuration/Services section. ADMIN means connection to the Kerio Administration Console program.

Secure

  Defines whether or not the connection will be secured by SSL (technical note: remote administration allows secured connection only.

Time

  How long the client has been connected. The timeout is used for certain services (i.e. if there is no data flowing through the connection for a certain period of time, the connection is terminated).

From

  IP address from which the client is connected. The DNS name of the client can be displayed here if the option Enable reverse DNS lookup for incoming connection is enabled in the Configuration → Advanced Options section (see chapter 12.6 Advanced Options). We recommend you to enable this option only if you intend to monitor where clients connect from since reverse DNS queries slow down traffic on the server.

User

  The name of the connected user. In some cases the name is not displayed (for example connections to the SMTP server — if user authentication is not required, the user remains anonymous).

Info

  More information about the connection (e.g. IMAP folder, administration program version, etc.).

Information in the Connections window is refreshed automatically or can be refreshed manually using the Refresh button.

### Active connection to WebMail interface

The table on this tab lists all users connected to the Kerio WebMail interface. Each row of the table contains information about a user (his/her email address), IP address used for connection to Kerio MailServer and the time when the connection ends.

Figure 24.4. Active WebMail Sessions

User

  A user connected via Kerio WebMail to Kerio MailServer.

Client address

  IP address of the computer used for connection to Kerio MailServer.

Expires

  After a certain time of inactivity (1 hour), Kerio WebMail logs out users automatically for security reasons.

Components

  Three different components can be used to connect to the server: Kerio WebMail (HTTP/WebMail), Kerio WebMail Mini (HTTP/WebMail Mini) and Kerio Web Administration (HTTP/WebAdmin).
