Nadav Tasher's questions

Here is my problem;

I have virtual-box running on Ubuntu 64 bit (17.04) and I have multiple virtual machines (all Ubuntu 64 bit).

I want to forward port 80, 25, 143 and 22 to all of the virtual machines, dns name specific.

For example;

ssh username@domain-1 --> domain-1-virtual_machine port 22

ssh username@domain-2 --> domain-2_virtual_machine port 22

etc.

I want that a request from domain-1 on a specific port will go to vm1 and a request from domain-2 on the same port will go to vm2.

thanks in advance

When i try:

$ adb devices

i get the result:

List of devices attached 
????????????    no permissions

what is the problem?

tried on an Ubuntu 16.04 machine and it worked perfectly. tried an 7.1.1 device and it also worked perfectly.
