Windows Agent can not connect using Launch agent by connecting it to the controller method

    • Icon: Bug Bug

    • core

      On Jenkins host I give the following set up for the agent:

       

      On my agent I first I download the agent.jar provided by my Jenkins server.
      Then I execute the command:

       

      java -jar agent.jar -jnlpUrl https://jenkins-chr.dev.po.precitecgroup.com/computer/foobar/jenkins-agent.jnlp -secret 2897bf216353c118d5bb0a96331c7e635584ec2628c68f551efdfe1e48c8df5b -workDir "c:\jenkins" -noCertificateCheck 

      Which was given by Jenkins, except the -noCertificateCheck 

      For which I get the following error log:

      Skipping HTTPS certificate checks altogether. Note that this is not secure at all.

      If I recall correctly this still worked with Jenkins: 2.401.1

       

      update:

      Jenkins was installed with apt.

      Jenkins is accessed directly without a reverse proxy.

      The following is the Jenkins config file:

      NAME=jenkins
      JAVA_ARGS="-Djava.awt.headless=true -Dhudson.slaves.WorkspaceList=_ -Xmx2G"

      The Jenkins server log when a connection is tried is the following:

      Jul 11, 2023 7:59:42 PM INFO hudson.TcpSlaveAgentListener$ConnectionHandler runAccepted JNLP4-connect connection #12429 from /192.168.60.91:54867
      Jul 11, 2023 8:00:02 PM INFO hudson.TcpSlaveAgentListener$ConnectionHandler runConnection #12430 from /192.168.60.91:54869 failed: null 

       

      After I enabled websocket connection on the server it now works. I had to import the self signed certificate to the java keystore. As the -noCertificateCheck option can not be used with websocket.

       

      So to sum it up: The normal connection does not work, but the websocket connection does.

          Mark Waite added a comment -

          I can't duplicate the issue that as described. I have Windows agents connected to my Jenkins 2.401.2 controller as inbound agents (one running AMD64 Windows 10 and one running ARM64 Windows). You'll need to provide much more information before others are likely to provide any help. See "How to report an issue" for the additional types of information needed.

          If that information is not provided, the issue will be closed as "Cannot reproduce".

          Do you have a firewall that blocks traffic on port 37670? Did you change the tcp listener port from fixed to random maybe?

          Description Original: On Jenkins host I give the following set up for the agent:

          !image-2023-07-11-12-45-21-682.png!

           

          On my agent I first I download the agent.jar provided by my Jenkins server.
          Then I execute the command:

          Which was given by Jenkins, except the -noCertificateCheck

          The Jenkins server log when a connection is tried is the following:
          {code:java}
          Jul 11, 2023 7:59:42 PM INFO hudson.TcpSlaveAgentListener$ConnectionHandler runAccepted JNLP4-connect connection #12429 from /192.168.60.91:54867
          Jul 11, 2023 8:00:02 PM INFO hudson.TcpSlaveAgentListener$ConnectionHandler runConnection #12430 from /192.168.60.91:54869 failed: null {code}
           

          After I enabled *websocket* connection on the server it now {*}works{*}. I had to import the self signed certificate to the java keystore. As the *-noCertificateCheck* option can not be used with websocket.

           

          So to sum it up: The normal connection does not work, but the websocket connection does.

          There is no firewall active on the server. 

          The  settings for the agent listener seem to be the default.

          I tried to reproduce the issue again. Now it is magically gone.
          The issue can be closed as I can't reproduce it myself.

          Thanks for all your time and consideration.

           

          Cheers!
