Specific permissions for connections from a terminal server

Edit online

Use IUCV statements to individually specify each target system to which the terminal server can establish an IUCV connection.

Through IUCV statements in the z/VM® directory entry of the terminal server, you can explicitly specify the target systems to which the terminal server can establish an IUCV connection.

Example: These statements allow connections to the z/VM guest virtual machines with the z/VM user IDs LXGUEST1, LXGUEST2, LXGUEST7, and LXGUEST9.

IUCV LXGUEST1
IUCV LXGUEST2
IUCV LXGUEST7
IUCV LXGUEST9

With such explicit statements, you can avoid granting permissions for IUCV connections that are not required or not intended.
