Longer keys may result in slower response time of the IP-KVM during connection establishment. 11.5.5 Serial Port Figure 72: Serial Port The IP-KVM Serial Settings allows you to specify what device is connected to the serial port and how to use it.
  • Page 96 Logically, connecting to the IP-KVM using a telephone line means nothing else than building up a dedicated point-to-point connection from your console computer to the IP-KVM. In other words, the IP-KVM acts as an Internet Service Provider (ISP) to which you can dial in. The connection is established using the Point-to-Point Protocol (PPP).

    Passthrough access to serial port via Telnet Using this option, it is possible to connect an arbitrary device to the serial port and access it (assuming it provides terminal support) via Telnet. Select the appropriate options for the serial port and use the Telnet Console, or a standard Telnet client to connect to the IP-KVM.

    11.5.7 Event Log Figure 74: Event Log Important events like a login failure or a firmware update are logged to a selection of logging destinations. Each of those events belongs to an event group, which can be activated separately. The common way to log events is to use the internal log list of the IP-KVM.
  • Page 99 Since the IP-KVM's system memory is used to save all the information, the maximum number of possible log list entries is restricted to 1.000 events. Every entry that exceeds this limit overrides the oldest one, automatically. Warning If the reset button on the HTML frontend is used to restart the IP-KVM, all logging information is saved permanently and is available after the IP-KVM has been started.

  • Page 103 To access a remote device using the RADIUS protocol you have to login, first. You are asked to specify your user name and password, then. The RADIUS server reads your input data (Authentication) and the IP-KVM looks for your profile (Authorization). The profile defines (or limits) your actions and may differ depending on your specific situation.
