Still someone could call conirmConnectivity, no? so the state isn't guarded from localhost tinkering anyhow. If you really need a solution you can acuire a token for this operation by setupNetworks, and confirm connectivity with this token passed back.

I'm not sure about the severity of the problem here, I'll let other reply, but I'm against this kind of solution.

Hello,

current VDSM ping verb has a problem - it confirms network
connectivity as a side-effect. After Engine calls setupNetwork it
pings VDSM host to confirm that external network connectivity is not
broken. This prohibits other users to call ping from localhost since
it would confirm connectivity even though networking could be broken.

In order to fix this problem ping should be split to ping2 (which just
returns Success with no side-effect) and confirmConnectivity. Change
on VDSM side was introduced in [1], we still need to expose new verbs
in Engine.

Regards,
Petr
