This portal is to open public enhancement requests against IBM System Storage products.

In the dsmserv.opt should be an option added to set the specified TCPPort listen only on a few single ip addresses and not on all, like now.
netstat -an | grep LISTEN
...
tcp4 0 0 *.1501 *.* LISTEN
...
This security issue occur if you run more then one TSM instance on one cluster node. (or on a single LPAR)
The TSM Server connection from the client to the server should be only able when you use the correct TCPSERVERAddress and TCPPort. We use of course instead of an ip address in the TCPSERVERAddress and DNS hostname.

Thank you for submitting the request. TCPport Listen limited to one single service IP address is not a security issue but a requirement about flexibility.
There are currently no plans to provide requested function. No IBM commitment is made or implies as to the
eventual delivery of an acceptable solution.
