We have created an issue in Pivotal Tracker to manage this. Unfortunately, the Pivotal Tracker project is private so you may be unable to view the contents of the story.

Consider going through the TLS troubleshooting guide and posting actual log/error messages from both server and client ends.

There can be perfectly legitimate reasons for TLS connections to fail even if everything is set up correctly as far as RabbitMQ is concerned: e.g. client certificate(s) are not trusted on the node.

[srbry]

Hi @michaelklishin thanks for responding. I had been going through the troubleshooting guide earlier. Everything was working as expected, SSL listeners being started etcs, however I cannot connect via SSL with the RabbitMQ nodes (on AMQP+SSL). All the SSL errors were relating to SSL handshakes. When I get access to the logs ill post some extra detail in here.

Has the latest release (v241) been tested with AMQP+SSL? I can't see anything obvious thats wrong in our config and it would very helpful to know if anyone else has it working so we can rule it out being a bug.

[michaelklishin]

@srbry you'd get a much more informed response if you post actual log entries from both sides plus openssl s_client output as demonstrated in the TLS troubleshooting guide. "Related to SSL handshakes" is not enough. Engineers need facts and cold hard data to work with.

To rule out any possible version-specific differences in behavior, simply deploy an older version and compare.

[srbry]

@michaelklishin I fully intend to get the data. I haven't got access to the system to re-run the tests right now so I was simply trying to establish if there were any known issues (or common misconfigurations)/ working deployments on the latest version.

[srbry]

@michaelklishin here are some more useful details.

From the above I can see that we are starting SSL Listeners, I have enabled the rabbitmq_auth_mechanism_ssl plugin, not sure if I need that or any others to make this work.

error: handshake failure - malformed_handshake_data

is definitely something to investigate, even though it's not very specific. Specifically malformed_handshake_data is very rare to see and seems to come down to an available cipher suite mismatch.

I don't know what cipher suites this release may be forcing by default but it is something that the user can control.

I am surprised to see

routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

output by s_client. If it really does use SSLv3 then it won't be able to connect because RabbitMQ disables SSLv3 by default. s_client can be instructed to use TLSv1 or later via CLI flags.

But it can be a red herring because the output against s_server contains

New, TLSv1/SSLv3

but then the two negotiate to use

Protocol : TLSv1.2

There are more threads for other Erlang-based projects that hint at cipher suite unavailability/mismatch.

Consider trying with OTP 20.3 to compare.

[gerhard]

SSL definitely works in this release, my hunch is that it's a configuration issue. Will provide more details when a deployment with SSL completes successfully.

[michaelklishin]

@gerhard @srbry I'd recommend a couple of things to make sure there's at least some overlap in the environments discussed:

• Switch to OTP 20.3 (no reason not do it)
• Use tls-gen for certificate generation if possible

There are too many variables at play otherwise. Thank you for your help, @gerhard.

[srbry]

Thanks @gerhard and @michaelklishin. I will also keep digging, I have currently configured rabbitmq to use all the ciphers that show up from rabbitmqctl eval 'ssl:cipher_suites(openssl).' so not sure what else we can do from that point of view.

I will give the switch a go. We are currently letting bosh int generate our certs but I can look at tls-gen if thats likely to make a difference. I will let you know how I get on!

[srbry]

@michaelklishin @gerhard using tls-gen seems to have resolved the issue. It does raise another question about using interpolate/ credhub (I haven't actually tried credhub yet) for doing the cert generation.

[srbry]

@michaelklishin @gerhard I am not giving in on this one, its a bit of a strange one. After upgrading to OTP 20.3 I can now see the following message in the logs:

2018-04-11 18:59:41.708 [info] <0.270.0> SSL WARNING: Ignoring a CA cert as it could not be correctly decoded.

Its a bit strange considering they are read exactly the same using openssl.

@gerhard @michaelklishin Another update. If you generate the certs using CredHub rather than just bosh interpolate the certs are readable so sounds like a bug between Erlang and the bosh interpolate process. Still not exactly sure why the certs are not compatible but using CredHub seems like a good solution anyway.

[mkuratczyk]

I'm closing this issue as it seems like it's been resolved. There are numerous deployments of this release with TLS enabled so it seems very specific to your environment. Also, credhub is probably the best option anyway.
