The host
Basic authentication
IOLAN+ will need to login to the authentication host with the log user name defined on the
Host Authentication And Logging screen. Therefore, you need to create an account to be
used by IOLAN+ (avoid csh shell). Make sure the user can log in successfully. Also, make
sure the user is not prompted for any input and ends up at a shell prompt.
User services authentication
This is used to provide services based upon the dial-in user’s name.
For example, user Mark always telnets to a specific IP address or user Alan needs to dial-in
and establish a PPP connection using a static IP address. This is accomplished by using a
PERL script which parses a RADIUS database. The PERL script ( RADparse) is on the Perle
CD or our website.
RADIUS is the TCP/IP protocol used for authenticating remote dial-in users. Although
IOLAN+ does not use RADIUS, a Perl based utility capable of using standard RADIUS
databases is available.
Otherwise, you can execute our PERL script during the user’s login. Under Unix, this script is
started from the etc/profile.
For Windows NT ® see the relevant section of the Perle website for the latest information.
See Appendix F Contacting Perle.
You then need to create a user database file. This is a sample file.
# Example of a PPP user with static address
alan Password
Framed-Protocol = PPP
Framed-Address = 204.17.209.1
# Example of a user with access to IOLAN+
