Hi all,
We’ve been trying out some mitaka packages as well as some Xenial hosts and
have been having some issues with rabbit and SSL.
If using rabbitMQ 3.6.x on Trusty I can’t get a mitaka host (oslo_messaging
4.6.1, python-amqp 1.4.9) to connect to rabbit over SSL.
If I use rabbitMQ 3.6.x on Xenial I can get it to work BUT I need to change
some settings on rabbit to allow some weaker ciphers.
I had to add the following to rabbitmq.config (found on some random blog and
haven’t investigated what exactly needed to change sorry)
{versions, ['tlsv1.2', 'tlsv1.1', tlsv1]},
{ciphers,
["ECDHE-ECDSA-AES256-GCM-SHA384","ECDHE-RSA-AES256-GCM-SHA384",
"ECDHE-ECDSA-AES256-SHA384","ECDHE-RSA-AES256-SHA384",
"ECDHE-ECDSA-DES-CBC3-SHA",
"ECDH-ECDSA-AES256-GCM-SHA384","ECDH-RSA-AES256-GCM-SHA384","ECDH-ECDSA-AES256-SHA384",
"ECDH-RSA-AES256-SHA384","DHE-DSS-AES256-GCM-SHA384","DHE-DSS-AES256-SHA256",
"AES256-GCM-SHA384","AES256-SHA256","ECDHE-ECDSA-AES128-GCM-SHA256",
"ECDHE-RSA-AES128-GCM-SHA256","ECDHE-ECDSA-AES128-SHA256","ECDHE-RSA-AES128-SHA256",
"ECDH-ECDSA-AES128-GCM-SHA256","ECDH-RSA-AES128-GCM-SHA256","ECDH-ECDSA-AES128-SHA256",
"ECDH-RSA-AES128-SHA256","DHE-DSS-AES128-GCM-SHA256","DHE-DSS-AES128-SHA256",
"AES128-GCM-SHA256","AES128-SHA256","ECDHE-ECDSA-AES256-SHA",
"ECDHE-RSA-AES256-SHA","DHE-DSS-AES256-SHA","ECDH-ECDSA-AES256-SHA",
"ECDH-RSA-AES256-SHA","AES256-SHA","ECDHE-ECDSA-AES128-SHA",
"ECDHE-RSA-AES128-SHA","DHE-DSS-AES128-SHA","ECDH-ECDSA-AES128-SHA",
"ECDH-RSA-AES128-SHA","AES128-SHA"]},
{honor_cipher_order, true},
Is anyone else had a play with this and got it working where a mitaka host can
talk to a rabbitmq server running on trusty?
The version or erlang is the difference here and I’m pretty sure that is where
the change is.
Cheers,
Sam
