I'm surprised (actually amazed) by the apparent default behavior of the FreeAXP telnet server for the console and serial port - they accept multiple concurrent connections from multiple ip addresses. This is completely counter-intuitive and seems a huge security hole ... have I missed something?

It is no different than any other application that is accessed via an IP port. It's a hole it you don't manager IP port access effectively. It is a feature if you want access to one of the virtual serial ports from a remote location.

I can see how it might be a useful feature to enable, but I can't see how this can be viewed as safe, as a default configuration.

Perhaps the following options should be available:
Allow concurrent connections - yes/no (default no)
Allow connections other than localhost - yes/no (default no)

I can't think of any common network application that would drop you into an existing session without any authentication, certainly not a console port.

HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?

The openvms disks question is frequently answered in the forums, and is not something to ask about in the shout box.
