Thanks for your help.
I've searched here and on google how to open the port, but i can't find something that works, do you have a correct command?
I just find some more informations that are maybe helpful(from setup.log):
```

See /tmp/opendj-setup-689375819839093057.log for a detailed log of this operation.
