[erlang-questions] How does running nodes() on host knows about all connected nodes?

[Harit Himanshu]

Hi

I am new to this and I am totally surprised how this works

I have a server (gru) and 3 minions talking to gru. But none of the minions
ever talked to each other.

Still when I run nodes() on any of the minions tells me which other minions
are connected.

*Gru*

(gru@REDACTED)7> nodes().

['minion1@REDACTED','minion2@REDACTED',

 'minion3@REDACTED']

(gru@REDACTED)8>

*minion1*

(minion1@REDACTED)6> nodes().

['gru@REDACTED','minion2@REDACTED',

 'minion3@REDACTED']

*minion2*

(minion2@REDACTED)2> nodes().

['gru@REDACTED','minion1@REDACTED',

 'minion3@REDACTED']

(minion2@REDACTED)3>

*minion3*

(minion3@REDACTED)2> nodes().

['gru@REDACTED','minion2@REDACTED',

 'minion1@REDACTED']

(minion3@REDACTED)3>



How does this process work? What's going on behind the scenes?

Thanks
+ Harit
