You changed the IP address of the host machine running simh, and that buggered your VMS licenses? I find that very difficult to wrap my brain around. VERY difficult. -Dave On 06/04/2013 06:14 PM, Tony Blews wrote: Aye, it is for VMS. I only mentioned the IP address stuff as last time I re-jigged my network I had the same problem and had to re-register it all. I'll try contacting Mr. Egolf before doing anything else. Tony.

So, now I've come to restart the thing, it seems my licenses have expired, which shouldn't have happened until September. Could this be down to moving the simh instance to a new machine and giving it a new ip address? That should have no effect on the licensing. The OS running under the emulator has no access to that information; it thinks it's a real VAX. Anyway, where do i get the licenses from again? All the addresses I had either don't work, or give me completely unrelated websites. I assume this is for VMS? I can send you a license if needed. -Dave -- Dave McGuire, AK4HZ New Kensington, PA -- Dave McGuire, AK4HZ New Kensington, PA
