I want to point out that the Internet Kermit Service can be configured to
execute any script the administrator wishes to have run when an end user
connects. The options are not SERVER or command prompt; but SERVER or
command processor.
The process for doing this is quite simple. Within the /etc/iksd.conf
script the administrator defines an on_login macro that is executed upon
successful login. This macro can test for the type of login by examining
the authtype, authname, and authstate variables. Based upon whether the
login is an authenticated user or a guest, different access configurations
can be applied and scripts can be selected.
The only reason for not using IKSD to provide a script to the end user
is if the script requires access to external commands which are disallowed
in IKSD configurations.
