    Modem Authentication & Logging 5 Modem Authentication & Logging IOLAN+ provides authentication support to validate users connecting to the serial port, and can update a host log file on connection states. Authentication and logging is achieved by using a designated authentication host to validate users and keep connection information.

  • Page 46: User Authentication/Logging

    + - User and Administration Guide IOLAN 5.1 User To improve access security, IOLAN+ has a mechanism for Authentication/ authenticating users before allowing them access. This is Logging accomplished by prompting the user for a Login ID and a password. IOLAN+ will then attempt to login to a specified host using that ID and password.

    + - User and Administration Guide IOLAN Log Username: The User ID IOLAN+ will use to log in to the authentication host and log messages. This user needs to be at a shell prompt to ‘cat’ messages to the log file. The password for the log user is set up under the IOLAN+ Administration Menu - Change option.

    The logger may be restarted via the kill command by adding two to the number of ports on your server (i.e. use four for an IOLAN+2, six for an IOLAN+4, ten for an IOLAN+8, eighteen for an IOLAN+16). If the host authentication succeeds, but logger fails to log events, then the port connection is dropped.

  • Page 153 Vmodem (Virtual modem) Vmodem is a feature of the IOLAN, which provides “modem like” communication between two IOLAN units on a network. This feature behaves like two modems connected across a telephone line. Typically, you use the Vmodem feature when you have multiple devices communicating with a central site. Vmodem allows you to achieve this using a single IOLAN unit at each end of the network without having to use multiple modems.
