As there is no password provided I was thinking that this case is ideal for a null authentication. Do you think that this solution is valid ? Can someone from INE or the community comment on it.
// by default the PPP process sends the hostname of the router if not set at the line command level: no need to precise the hostname via a ppp chap host xxxx. You can argue that it is safer to precise it on a real network, but into the context of the lab and this question it sounds correct.
