            How to configure correctly an authentication using Tomcat 10?
            Asked 2021-Jun-10 at 13:44

            I'm using Tomcat 10 and eclipse to develop a J2E (or Jakarta EE) web application. I followed this tutorial (http://objis.com/tutoriel-securite-declarative-jee-avec-jaas/#partie2) which seems old (it's a french document, because i'm french, sorry if my english isn't perfect), but I also read the Tomcat 10 documentation.
            The dataSource works, I followed instructions on this page (https://tomcat.apache.org/tomcat-10.0-doc/jndi-datasource-examples-howto.html#Oracle_8i,_9i_&_10g) and tested it, but it seems that the realm doesn't work, because I can't login successfully. I always have an authentification error, even if I use the right login and password.
            I tried a lot of "solutions" to correct this, but no one works. And I still don't know if I have to put the realm tag inside context.xml, server.xml or both. I tried context.xml and both, but i don't see any difference.

            Apache ActiveMQ Artemis MQTT broker refuses connections - possible connection limit
            Asked 2021-Jun-05 at 14:53

            I'm running Apache ActiveMQ Artemis 2.17.0 inside VM for a month now and just noticed that after around 90 always connected MQTT clients Artemis broker is not accepting new connections. I need Artemis to support at least 200 MQTT clients.

            What could be the reason for that? How can I remove this "limit"? Could the VM resources like low memory be causing this?

            After restarting Artemis service, all connection are dropped, and I'm able to connect again.

            I was receiving this message in logs:

            ...

            ANSWER

            Answered 2021-Jun-05 at 14:53

            ActiveMQ Artemis has no default connection limit. I just wrote a quick test based on this which uses the Paho 1.2.5 MQTT client. It spun up 500 concurrent connections using both normal TCP and WebSockets. The test finished in less than 20 seconds with no errors. I'm just running this test on my laptop.

            I noticed that your journal-buffer-timeout is 700000 which seems quite high which means you have a very low write speed of 1.43 writes per millisecond (i.e. a slow disk). The journal-buffer-timeout that is calculated, for example, on my laptop is 4000 which translates into a write-speed of 250 which is significantly faster than yours. My laptop is nothing special, but it does have an SSD. That said, SSDs are pretty common. If this low write-speed is indicative of the overall performance of your VM it may simply be too weak to handle the load you want. To be clear, this value isn't related directly to MQTT connections. It's just something I noticed while reviewing your configuration that may be indirect evidence of your issue.

            The journal-buffer-timeout value is calculated and configured automatically when the instance is created. You can re-calculate this value later and configure it manually using the bin/artemis perf-journal command.

            Ultimately, your issue looks environmental to me. I recommend you inspect your VM and network. TCP dumps may be useful to see perhaps how/why the connection is being reset. Thread dumps from the server during the time of the trouble would also be worth inspecting.

            I was expecting segmentation fault or some kind of out of bound exception but did not get it when using command line arguments in a C program
            Asked 2021-May-30 at 09:48

            I am learning C programming from "Learn c the hard way by Zed Shaw". He asks the learner to try and break their own code.

            So I tried the following C code and thought printing more values that I gave argv will break it but it did not until later.

            ...

            ANSWER

            Answered 2021-May-30 at 09:48

            A segmentation fault happens when the code try to access a memory region that is not available.

            Accessing an array out of bounds doesn't means that the memory before or after the area occupied by the array is not available: The compiler or the runtime usually put all varibales or data in general in a given block of memory. If your array is the last item of such a memory block, the accessing it with a to big index will produce a Segmentaion Fault but is the array is in the middle of the memory block, you will just access memory used for other data, giving unexpected result and undefined behavior.

            If the array (In may example, but valid for anything) is written, accessing available memory will not produce a segmentation fault but will overwrite something else. It may produce unexpected results or crash or segmentation fault later! This kind of bug is frequently very difficult to find because the unexpected result/behavior looks completely independent of the root cause.

            ANSWER

            Answered 2021-May-11 at 23:49

            First, it's important to note that there's no feature to make a client reconnect to the broker from which it disconnected after the client crashes/restarts. Generally speaking the client shouldn't really care about what broker it connects to; that's one of the main goals of horizontal scalability.

            It's also worth noting that if the number of messages on the brokers and the number of connected clients is low enough that this condition arises frequently that almost certainly means you have too many brokers in your cluster.

            That said, I believe the reason that your client isn't getting the messages it expects is because you're using the default redistribution-delay (i.e. -1) which means messages will not be redistributed to other nodes in the cluster. If you want to enable redistribution (which is seems like you do) then you should set it to >= 0, e.g.:

            Tomcat - Allow remote access to specific webapp folders
            Asked 2021-May-11 at 22:21

            I have tomcat 9 installed on Ubuntu VPS. I have two web applications deployed. Say -

            1. $CATALINA_BASE/webapps/app1
            2. $CATALINA_BASE/webapps/app2

            Both of them are deployed as war files generated from spring boot application

            Now, I want only app1 to be accessible to outside network. app2 should be accessible only from localhost i.e. app1.

            I am looking for more global solution where I can modify server.xml or something like that which stays even after deployment.

            What I already tried

            • Added context.xml inside webapp/app2 and add a valve to restrict outside traffic. But, this context.xml is getting overwritten after every deployment .

            • Created $CATALINA_BASE/conf/context.xml and added valve to restrict remote traffic. This blocked remote access to all apps.

            Then, I created $CATALINA_BASE/conf/Catalina/localhost/app1.xml and overrided context through

            Tomcat is not reading your deployment descriptor c.xml. As you can see in the logs you have:

            Unable to create directory for deployment: [/opt/tomcat/conf/Catalina/localhost]

            Once you create the required directory /opt/tomcat/conf/Catalina/localhost and put your c.xml file in it, the starting logs will contain:

            Deploying deployment descriptor [/opt/tomcat/conf/Catalina/localhost/c.xml]

            instead of:

            Deploying web application archive [/opt/tomcat/webapps/c.war]

            and your valves should work.

            Note - After creating xml file, change owner of both file and directory to tomcat user so that tomcat can deploy xml files

            sudo chown tomcat:tomcat ${CATALINA_HOME}/conf/Catalina/localhost/ sudo chown tomcat:tomcat ${CATALINA_HOME}/conf/Catalina/localhost/ROOT.xml
