I'm on cluster with 2 nodes sharing the same SYSUAF.
To me as a user there is absolutely no difference between
the two nodes. Most of the time I'm not even sure which
of the machines I'm working on.
My question is this: If the two nodes share the same SYSUAF
why do I then need to be validated through the proxy database
when I do things like DECnet task-to-task or TCP/IP rexec
between the two nodes in the cluster ?
(or is this my misunderstanding ?)
The Answer is:
This behaviour is a result of the default behaviour of the networking
protocols -- the protocols have not been configured to recognize that
the incoming connection as part of the same cluster. One uses the
concept of a "proxy" to configure this, and both DECnet and Digital's
IP package support proxies.
There are security implications involved in configuring proxies, so
a review of the documentation around configuring and using proxies
is advisable.
