Status Information Refresh This option refreshes information in the Active Hosts window immediately (this function is equal to the Refresh button displayed at the bottom of the window). Auto refresh Settings for automatic refreshing of the information in the Active Hosts window. Information can be refreshed in the interval from 5 seconds up to 1 minute or the auto refresh function can be switched off (No refresh). Logout user Immediate logout of a selected user. Logout all users Immediate logout of all firewall users. Manage Columns By choosing this option you can select columns to be displayed in the Active Hosts window (see chapter 3.3). Detailed information on a selected host and user Detailed information on a selected host and connected user are provided in the bottom window of the Active Hosts section. Open the General tab to view information on user’s login, size/speed of transmitted data and information on activities of a particular user. Figure 19.3 Information about selected host/user — actions overview 254
19.1 Active hosts and connected users Login information Information on logged-in users: • User — name of a user, DNS name (if available) and IP address of the host from which the user is connected • Login time — date and time when a user logged-in, authentication method that was used and inactivity time (idle). If no user is connected from a particular host, detailed information on the host are provided instead of login information. Figure 19.4 Host info (if no user is connected from it) • Host — DNS name (if available) and IP address of the host • Idle time — time for which no network activity performed by the host has been detected Traffic information Information on size of data received (Download) and sent (Upload) by the particular user (or host) and on current speed of traffic in both directions. Overview of detected activities of the particular user (host) are given in the main section of this window: Activity Time Time (in minutes and seconds) when the activity was detected. Activity Event Type of detected activity (network communication). Kerio Control distinguishes between the following activities: SMTP, POP3, WWW (HTTP traffic), FTP, Streams (real-time transmission of audio and video streams) and P2P (use of Peer-to-Peer networks). Note: Kerio Control is not able to recognize which type of P2P network is used. According to results of certain testing it can only "guess" that it is possible that the client is connected to such network. For details, refer to chapter 8.4. Activity Description Detailed information on a particular activity: • WWW — title of a Web page to which the user is connected (if no title is available, URL will be displayed instead). Page title is a hypertext link — click on this link to open a corresponding page in the browser which is set as default in the operating system. Note: For better transparency, only the first visited page of each web server to which the user connected is displayed. For detailed information about all visited pages, refer to Kerio StaR (see chapter 21). • SMTP, POP3 — DNS name or IP address of the server, size of downloaded/uploaded data. 255
