    The Dial-Out support by the Perle 833 allows users on a LAN workstation to connect to a destination that is external to their LAN. This is done by dialing out via a Perle 833 server modem instead of a modem attached directly to the users’s PC. For dial-out users, the benefit of sharing these modems across a network is that they can make efficient use of the hardware and phone lines that are already installed on the network.

    Agent detects a serious condition or activity, it will send a “trap” to a specified host, known as the trap host. The trap host must be a member of a community which is known to the SNMP Agent. The Perle 833 sends trap messages when the unit restarts and when it detects an invalid logon attempt.

  • Page 111: Event Log

    Chapter 9: Network Administration Event Log The Perle 833 records many of the events and activities that can be performed on the server by the manager during configuration as well as events from normal dial-in and dial-out use. This event log can be used to monitor the Perle 833 for proper usage and for tracking some kinds of problems.

  • Page 112: Software Upgrades

    Software Upgrades Software Upgrades Firmware is the basic operating code of a Perle 833. When new versions of firmware become available, they can be conveniently downloaded to your Perle 833. Note: Be sure all users are disconnected before performing a download. Any existing user ses- sions will be abruptly terminated when the Perle 833 is reset.

  • Page 113: Chapter 10: Security

    The Perle 833 has two methods to control access to the server’s internal configuration settings. Administrative Privileges The Perle 833 will only accept a connection from the Perle 833 Manager program if the user has been configured with administrative privileges. The user record for this administrator must be stored as part of the Perle 833 configuration file and have a valid password.

  • Page 114: Network Access

    You must select either PAP or CHAP, or both. Netware Netware Bindery contains a user profile database that is stored on a Netware server. The Perle 833 will ask the Netware server to authenticate the password against the database before allowing the user access to the LAN.

  • Page 115: Pap And Chap

    Passwords will be authenticated by an external security device that is physically connected between a Perle 833 serial port and its modem. These devices send login requests to the dial-in clients. The clients must support a TTY or terminal mode to complete the login process. The Perle 833 User List base will not be used for password authentication.

  • Page 116: Call Back

    The Call back feature of the Perle 833 can provide an additional level of security. When a remote user calls in to a Perle 833 and Call Back has been set up, the Perle 833 will disconnect and then call the user back according to the Perle 833’s configuration for the user.

  • Page 117: Security Services Configuration

    If the network protocol used to communicate with the PDC is IP then enter the PDC’s IP address. This value must be configured if the PDC is not on the same IP subnet as the Perle 833. Allow User Specified NT Domain Click the check box to allow a dial-in user to specify a domain to which they belong.

  • Page 128: Generic User

    When using a security system such as Axent or SecurID, you may want to provide additional Perle 833 functionality even though the user has not been directly authenticated by the Perle 833. This can be done by setting up a generic user record which is used whenever a user connects.
