Instance of Ubuntu with Linux-based tools

The vlan is a virtual network of linux machines.
|
|
|
|
|
We have one master and multiple workers.
|
|
|
|
|
We get initial access to the master and from there we can use the workers.
|
|
|
|
|
The master has all he tools needed for:
|
|
|
|
|
- advanced system programming
|
|
|
|
|
- linux networking
|
|
|
|
|
- linux administration
|
|
|
|
|
- general operating system development
|
|
|
|
|
|
|
|
|
|
Inside the master we have user access while in our workers we have sudo access whithout password.
