External communication
Define the following ports to your firewall that protect the z/OS® host, as they are used for
client-host communication (using the
tcp
protocol): - Debug manager services, default port
5335
. The port can be set in theDBGMGR
started task JCL. Communication on this port can be encrypted. - When z/OS Debugger is
started with Language Environment® (LE) option
TEST(
,,,TCPIP&&ipaddress%8001:*
) or TEST(,,,DIRECT&&ipaddress%8001:*
), it is instructed not to use Debug Manager but contact the Eclipse client directly at port 8001. This implies, from a TCP/IP perspective, that z/OS Debugger is a client that contacts a server (the Debug UI) in the Eclipse IDE.
