I'm a bit confused. First part sounds like a normal login-shell, the second part sounds like you want to 'log in to the kernel'. I assume the latter, as the first has several implementations already. This is not doable in several different ways. First off, 'connecting to the internet'. Even though the kernel handles all the network traffic and the state of the TCP/IP stack is altered by this traffic, it is not directly affected by it. It merely handles the traffic and passes it along. Secondly, you want to authenticate users, and this is typically a user-space application job. Note that the kernel does not include any user space libraries (like libc with friends). So how should users connect and authN in the first place - you would have to implement all of that yourself. Thirdly, and IMHO most important: this is *wrong*. You want to enable 'anyone' from the Internet to execute code _in_kernel_space_ remotely on a given computer?
