Hello Guys!
I have been trying to install ejabberd server on Amazons EC2 instance.
I am kinds a stuck at this step right now. I am following this guide: http://tdewolf.blogspot.com/2009/07/clustering-ejabberd-nodes-using-mnes...
From the guide I have sucessfully completed the Set up First Node (on ejabberd1) part. But am stuck in part 4 of Set up Second Node (on ejabberd2)
So all in all, I created the main node and am able to run the server on that node and access its admin console from then internet. In the second node I have installed ejabberd. But I am stuck at point 4 of setting up the node instruction presented in this blog (http://tdewolf.blogspot.com/2009/07/clustering-ejabberd-nodes-using-mnes...).
I execute this command "erl -sname ejabberd@domU-12-31-39-0F-7D-14 -mnesia dir '"/var/lib/ejabberd/"' -mnesia extra_db_nodes "['ejabberd@domU-12-31-39-02-C8-36']" -s mnesia" on the second server and get a crashing error:

any idea what going on? I am not really sure how to solve this problem :S how to let ejabberd only access register from one special server? ›
Is that the right way of copying .erlang.cookie file?
Submitted by privateson on Sat, 2010-05-29 00:11.
before this I was getting this error (see below), I solved it by running this command: chmod 400 .erlang.cookie
Also to copy the cookie I simply created a file using vi on the second server and copied the secret code from server one to the second server. Is that the right way of copying .erlang.cookie file?
