Any number of issues on an SSL certificate can prevent an SSL handshake from being completed. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I'm using private IPs for the 'listen_address' and public IPs for the 'broadcast_address', which I believe is the correct setup. Free and premium plans, Customer service software. For the first step, create the CA using the following configuration file titled gen_ca_cert.conf in the current directory: Obviously, youll want to put your specific information in there. So now that we have all of our files created, lets place them where they go so CCM can find them. The exact steps in an SSL handshake vary depending on the version of SSL the client and server decide to use, but the general process is outlined below. If you verify that your browser and server are using the same protocol, then move on to the next step. As a result, authentication of the web server is banned followed by the opposite steps. For encrypting inter-node traffic for our cluster, it means that each node has a trust relationship with the rest of the cluster which can be verified against a local Trust Store. Without authenticating that we are indeed talking to another Cassandra node, we can write a program to attach to a cluster and execute arbitrary commands, listen to writes on arbitrary token ranges, even inject an administrator account into the system_auth table with specially crafted message packets. message details. rev2023.6.2.43474. Another reason you could be getting the SSL Handshake Failed error is that the client and server are using different Cipher Suites. Cassandra; CASSANDRA-17631; on SSL Handshake issues org.apache.cassandra.net.InboundConnectionInitiator$Handler spams log as it can not remove itself handling exception: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake AWT-EventQueue- . Created a certificate authority for my cluster, Created a keystore and truststore for each node and added my CA certificate chain to both, Generated a key pair and CSR for each node, signed it with my CA, and added the resulting certificate to each node's keystore, Updated each node's configuration as reads below, Ensure that the CA generates node certificates with. truststore_password: ************************. Example: ARTICLE1.MNO and ARTICLE1.PQR make sure your OS has access to the .PQR file. Thats because older cipher suits tend to be vulnerable and fewer safe. We build on that process here by actually installing everything on a local three node cluster. Last error: _ssl.c:344:error:00000000:lib(0):func(0):reason(0)")}). However, most of the problems are server sided. rev2023.6.2.43474. However, were these steps used in building a production deployment, they would create a substantial maintenance burden and be quite difficult to automate. require_client_auth: false Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I had set up a 6-node Cassandra cluster spanning two AWS regions / datacenters (3 in each) and everything was working fine. Why wouldn't a plane start its take-off run from the very beginning of the runway to keep the option to utilize the full runway if necessary? Also try to use a wrong password for keystore_password and see if cassandra really throws an exception as expected. With each key store now containing our CA, we can import the signed certificate with the same alias back into the key store: Our key store is now all set. Beginning at 2016-10-18T07:39, (and continuing to present) Cassandra nodes in the RESTBase cluster began logging the following at 1 minute intervals. Well put that knowledge to immediate use by configuring inter-node encryption on a local CCM cluster. If the above option works, never mind. Using the CN attribute for the hostname is considered deprecated in the context of PKI. Over 2 million developers have joined DZone. Some additional info on why you need to do this can be found here. | The take away is to pick something that will make managing these easy. Does substituting electrons with muons change the atomic shell configuration? Is Spider-Man the only Marvel character that has been represented as multiple non-human characters? Find centralized, trusted content and collaborate around the technologies you use most. With our key stores created and populated, we now need to export a certificates from each nodes key store as a Signing Request for our CA: Weve seen two new keytool options here which well briefly describe: With the certificate signing requests ready to go, its now time to sign each with our CAs public key via OpenSSL: This OpenSSL incantation is quite a bit different than our the one for creating a CA above, so well again summarize: With the certificates now signed, we will need to re-import them back into each nodes key store via the -import sub-command of keytool. Does the conduit for a wall oven need to be pulled inside the cabinet? This is how each node will verify incoming connections from the rest of the cluster. Maybe its unable to attach with the SNI servers. The server has no trust relationship with that client, its just using the certificate to encrypt the communication. keystore_password: ************************ There is currently a limitation in Cassandra which forces us to use the same password for the key store as for the key. Your options are limited. What Is an SSL Handshake? So always try updating your cipher suites. It's the phenomenon by which your browser proposes a secure connection to an internet server. But since we are using Client Certificate Authentication, we need to add a trust store to each node. The client and server do not support the same SSL version. Is there any evidence suggesting or refuting that Russian officials knowingly lied that Russia was not going to attack Ukraine? subsidiaries in the United States and/or other countries. TLS has replaced SSL, but SSL is still a more commonly used term so well continue to use it in this post. Running Cassandra in the foreground I can see a ton of SSL errors tracing out, all of which complain of handshake failure, because: In an attempt to solve this problem I have switched to the Oracle JRE (I was being lazy and using OpenJDK before) and installed the JCE unlimited strength cryptography policy files to ensure all possible ciphers would be supported. Created a cqlshrc conf file and filled it following this guide https://docs.datastax.com/en/cassandra/2.1/cassandra/security/secureCqlshSSL_t.html : [connection] What have solved this was adding the line of the SSL version at cqlshrc file: Thanks for contributing an answer to Stack Overflow! This allows us to create a Root Certificate that can be used to sign all of our server-specific certificates. The slides are available and the SSL Certificates: a brief interlude section is probably the most expedient route if you are impatient.

Learn about issues experienced with OpsCenter and solutions or workarounds. Because like most examples of generating certificates and configuring SSL, the documentation still holds to the model of a client, like a web browser, talking to a server. Negative R2 on Simple Linear Regression (with intercept). First, well move the key stores: Note: we make the target name here generic for the sake of convention as this is what you would do with a CM system anyway. In trying to get python dtests stable after CASSANDRA-17594 the following error was detected on trunk (see https://app.circleci.com/pipelines/github/dcapwell/cassandra/1472/workflows/4cf41e3a-21bc-4657-9ec2-d4468e3ac8b2/jobs/12233 sslnodetonode_test.py::TestNodeToNodeSSLEncryption::test_ssl_correct_hostname_with_validation): It looks like handshake errors cause org.apache.cassandra.net.InboundConnectionInitiator$Handler to run but fail to remove its self as it no longer exists in the pipeline. As with the presentation mentioned above, we will break this down into the following: Being further down the stack, most developers are not exposed to encryption in their day to day work.

Sometimes the client, and therefore, the server cannot establish the. After getting that much working I attempted to enable internode encryption which I cannot get to work properly, despite reading innumerable documents on the subject and fiddling endlessly. Specifically, loading individual certificates with different passwords from a key store is shockingly cumbersome, particularly if one or more of those entries is based on a trust chain. Its the phenomenon by which your browser proposes a secure connection to an internet server. If used, the -validity is then calculated as being from that point in time onwards.

Create a directory for the CA and then change to that directory: mkdir -p dse/root/ca. Just like a protocol mismatch, a client and server who do not have mutual support for the same CipherSuite will not be able to establish a secure connection. You would possibly lose all the items that you simply have stored over time. Let's chat. Setting this option (as well see in the steps below) enables Client Certificate Authentication as previously discussed. Why is Bb8 better than Bc7 in this position?

SSL Handshake Failed is an error message that occurs when the client or server wasn't able to establish a secure connection. document.getElementById("copyrightdate").innerHTML = new Date().getFullYear(); You can enable DNS hostname verification (referred to as Subject Alternative Name in PKI parlance), but since we building our own CA for private consumption, I consider it overkill for this case. Then click on Settings. To use this, we need to install the strong encryption policy files into our JDK. The max duration for an SSL/TLS certificate is two years (27 months because CAs will allow you to carry up to three months over from your previous certificate). For this tutorial, I was using OpenSSL 1.0.1j 15 Oct 2014 on OS X 10.10.5. This could also be said for the client.
