How to save the modified interfaces file (for the new IPs).
Im trying to set up multiple whonix gateway and workstation VMs.
I have no linux skills whatsoever.
I managed to open the interfaces file with the terminal comand “sudo nano…interfaces” and changed the IPs like suggested in the guide on whonix.org… but i dont know how to save those changes in the file.
If i just close the terminal and re-open the file, its back to its original state… i googled for a guide to modify and save a file with the terminal on linux already, but didnt find a working solution.
so which key-combination do i have to press? or what do i have to type?
thx in advance
