[rabbitmq-discuss] Overriding node long name

Mon Oct 5 17:13:17 BST 2009

Hi Sammy,

If you edit the rabbitmq-server script and change the -sname to -name,
then yes, you can set RABBITMQ_NODENAME to be foo at ip-address and that'll
work fine. Note that you'll also probably need to edit the other scripts
similarly to make them continue to work (rabbitmqctl, rabbitmq-multi
etc) - an sname node can't connect to a long name node (and vice versa).
