Wrong host id for academic licence


#1

I try to get my academic license. to do it I need to provide Host ID .
when I run cvx_version I get that the host id is:
Host ID: 00000000000000e0 (net1)
but when I try to fill it in the license request is says that the host ID should be 11 characters.
I also see that mine ends with (net1) while in the example it ends with (en0).

I’m afraid CVX Professional won’t work on this computer if it can’t secure a standard Ethernet host ID. The standard version of CVX will continue to work however.

I am having the same problem with cvx_version returning a host ID that does not seem to be a “standard Ethernet host ID.” Here’s the output that I get with the input “cvx_version”:

As can be seen, I do have an academic license, and I attached the strange Host ID that I’m getting (by merely chopping off four of the leading zeros). The second host ID I’ve attached is the result of a previous installation from a few months ago on the same computer with the same network card. It pulled a valid hostid then, and I’m not sure why it’s having issues now.

Do you have any suggestions on having cvx_version secure a standard host ID? Or could you perhaps point me toward some references that might help resolve this situation? I apologize about the naivety of the questioning, but I’m a bit lost on these matters.

When I run cvx_version to obtain a username and host ID for an academic license, I seem to get an invalid response. Here’s the output that I get with the input “cvx_version”:

I’m not the first to have this problem, and I posted on the other thread as well. Since I didn’t get a response, I’m trying to start a new topic to see if that will garner any assistance.

Does anyone have any suggestions on having cvx_version secure a standard host ID? Or are there any suggested references that might help resolve the situation? I apologize about the naivety of the questioning, but I’m a bit lost on these matters.

Starting a new thread, I’m afraid, will not help. In fact, I’m going to be merging this into the other thread.

We simply don’t have an answer for you. I don’t know why your Java subsystem, from which this host ID is retrieved, is giving a non-standard result. But I simply cannot issue licenses without a valid host ID. You will have to use a different computer or use the free solvers.


(Edward Chien) #6

Thank you for the response. Perhaps I’ll try to investigate the Java subsystem or use a different computer.

I met the same question today, and slove it by closing the Tunnel adapter 6to4 Tunneling Pseudo-Interface in WIN10.


(Michael C. Grant) #8

Oh, now this is a great lead, thanks @luoying.
