Erlang nodes can't see each other

Question

I am new to Erlang and trying to set two nodes on my laptop.

In one terminal I type:

eli@elimayost: ~/erlang_apps> erl -sname foo -setcookie secre         


        

Answer 1

Try starting the nodes like this:

eli@elimayost: ~/erlang_apps> erl -sname foo@elimayost -setcookie secret
eli@elimayost: ~/erlang_apps> erl -sname bar@elimayost -setcookie secret

Then ping them like you did before.

(foo@elimayost)1> net_adm:ping(bar@elimayost).

If that doesn't work for you, try pinging the node from itself.
