 It's a little more than that. The .bash_profile auto-logon trick is
intended to shield the user from the O/S. Additionally; you have the
compliance of the MV service to consider. How hard is it for an ordinary
user to gain TCL access and also their home directory. Do they automatically
get root privs if that happens? If they do, flog the admin with STP cable
after immediately fixing that huge security hole.

 True, but the merchant is only responsible for the data they store and
handle. They are not responsible for the transmission and routing of the
data if it is being sent to a clearing house using "compliant" means
(SSL/phone/etc).

 I'll remember that when we get audited. :)

  I didn't want to say that so explicitly in my first response, but I have
to agree about the SQL agenda. If CISP/PCI was really the issue then a quick
Google search would provide plenty of help in securing the telnet
connectivity without having to completely eliminate it. 

 Brenda; BTW an even more secure option than what I stated before is to
establish an OpenVPN connection between the MUMPS and UV server. You could
then secure the telnet connection in a DES3 tunnel. I think that's
horrendous overkill for a firewalled LAN, but if the admin is really that
paranoid then every machine on the LAN should be tied together via VPN.
