    IP-KVM switch. 6.1.3 Telnet Console The IP-KVM switch firmware features a Telnet server that enables a user to connect via a standard Telnet client. In case the Telnet program is using a VT 100, VT 102 or VT 220 terminal or an according emulation, it is even possible to perform a console redirection as long as the IP-KVM switch host machine is using a text mode screen resolution.
  • Page 39 Connecting to the IP-KVM switch is done as usual and as required by the Telnet client, for instance in a UNIX shell: Replace the IP address by the one that is actually assigned to the IP-KVM switch. This will prompt for username and password in order to log into the device. The credentials that need to be entered for authentication are identical to those of the web interface.

  • Page 49 Manually Allows to adjust both compression rate and the colour depth individually. Depending on the selected compression rate the data stream between the IP-KVM switch and the Remote Console will be compressed in order to save bandwidth. Since high compression rates are very time consuming, they should not be used while several users are accessing the IP-KVM switch simultaneously.

  • Page 56: Dynamic Dns

    (see Figure 6-21 ): Figure 6-21. Dynamic DNS Scenario The IP-KVM switch is reachable via the IP address of the DSL router, which is dynamically assigned by the provider. Since the administrator does not know the IP address assigned by the provider, the IP-KVM switch connects to a special dynamic DNS server in regular intervals and registers its IP address there.
  • Page 57 The administrator has to register an IP-KVM switch that is supposed to take part in the service with the Dynamic DNS Server and assign a certain hostname to it. He will get a nickname and a password in return to the registration process. This account information together with the hostname is needed in order to determine the IP address of the registered IP-KVM switch.

  • Page 58: Security

    If this option is enabled access to the web front-end is only possible using an HTTPS connection. The IP-KVM switch will not listen on the HTTP port for incoming connections. In case you want to create your own SSL certificate that is used to identify the IP-KVM switch refer to the Section called Certificate .
  • Page 59 Default policy This option controls what to do with arriving IP packets that do not match any of the configured rules. They can be accepted or dropped. If you set this to “ DROP ” and you have no “ ACCEPT ” rules configured, the access to the web front-end over LAN is actually impossible! To enable access again you can change the security settings via modem or by temporarily disabling IP access control with the initial configuration procedure (see Table 4-1 )

  • Page 60: Certificate

    • It is also possible to use the serial console as for the initial configuration (see Table 4-1 ) and login as the user “ unblock ” . The IP-KVM switch will ask for the super user password and present a list of blocked users, which may be unblocked.
  • Page 61 • Send the saved CSR to a CA for certification. You will get the new certificate from the CA after a more or less complicated traditional authentication process (depending on the CA). • Upload the certificate to the IP-KVM switch using the “ Upload ” button as shown in Figure 6-24 After completing these three steps, the IP-KVM switch has its own certificate that is used for identifying the card to its clients.
  • Page 62 If you destroy the CSR on the IP-KVM switch there is no way to get it back! In case you deleted it by mistake, you have to repeat the three steps as described above. Common name This is the network name of the IP-KVM switch once it is installed in the user's network (usually the fully qualified domain name).

  • Page 63: Serial Port

    6.5.5 Serial Port The IP-KVM switch Serial Settings (Figure 6-25 ) allow you to specify what device is connected to the serial port and how to use it. Configuration or console login Do not use the serial port for any special function, use it only for the initial configuration (see Table 4-1 ).
  • Page 64 Serial line speed The speed the IP-KVM switch is communicating with the modem. Most of all modems available today will support the default value of 115200 bps. In case you are using an old modem and discovering problems try to lower this speed.

    6.5.6 Date And Time This link refers to a page, where the internal real-time clock of the IP-KVM switch can be set up (see Figure 6-27). You have the possibility to adjust the clock manually, or to use a NTP timeserver.

  • Page 66: Event Log

    The common way to log events is to use the internal log list of the IP-KVM switch. To show the log list, click on “ Event Log ” on the “ Maintenance ” page. In the Event Log Settings you can choose how many log entries are shown on each page.
  • Page 67 To receive this SNMP traps, any SNMP trap listener may be used. In contrast to the internal log file on the IP-KVM switch, the size of the NFS log file is not limited. Every log event will be appended to the end of the file so it grows continuously and you may have to delete it or move it away from time to time.
