Re: Connect via PC

John and Booth,
My best answer is to read the AS/400 book "Tips and Techniques for
Securing the AS/400", SC41-3300, or SC41-5300, depending on your release.
This book has a chapter on "Securing your APPC communications" and
another on "Securing you TCP/IP communications".

In general, with TCP/IP, security is dependant on the application they
are connected to.  With APPC, it is possible to do some things with
either QUSER authority, or the authority of the user profile that started
the initial connection.

I've interspersed comments below.

It really depends what application they're connected to.  The
security may be great, or it may be non-existant.

                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Well, a 5250 terminal with either the router user-profile signed on, or
QUSER signed on.  the key is to give QUSER or the 'router user-profile'
limited access to your AS/400.
