Cannot check out license on another machine

I’m having a lot of problems installing this darn thing.

I suspect the FQDM is creating problems with the lmgrd, so I change the environment variable to be just the host name without the string “.localdomain”. Still the problem persists.

On other machines simply sayys I cannot connect.

This is Linux.

Any commands to check that it tries to connect to the correct port?
Shall I be explicit about the port? How to set this up?

Thanks,

Pedro
