Sounds like a fertile ground for deadlocks :-)

Windows 95, as you know, offers no such thing as remote logins and therefore
no security for them. Kermit 95 offers three levels of security:
1. None: anybody who can dial the number gets in.
2. One-user/one-password authentication built into the K95 server
via SET SERVER LOGIN. Anybody who can dial the number and knows the
username and password gets in.
3. Host mode, which not only supports multiple userid/password
combinations, but also enforces filesystem access restrictions.
(1) and (2) generally are implemented using a script that waits for the
connection and then puts Kermit 95 in server mode. A variety of security
measures are possible with the SET SERVER and DISABLE commands.
(3) presents itself interactively to the caller and is therefore less
usable from scripts.

:
So you might try K95 server mode with the desried services DISABLEd, and
with LOG TRANSACTIONS, which records failed and successful logins in the
log file of your choice.
