    After run agent, waiting for download

      Hi

      after run agent on slave machine freeze in this step:

      [machine@slave ~]$ /opt/rhq-agent/bin/rhq-agent.sh start

      Unused option: start

      RHQ 4.12.0.JON330GA Update 12 [e80b551] (Sat Jun 22 07:06:55 IRDT 2019)

      The agent is waiting for plugins to be downloaded...

      >

       

      Workaround:

      • ping master and slave with ip and name successful
      • add ip and name in hosts file
      • no proxy
      • no firewall! No iptable on slave and master
      • Permission of /opt = 777
      • Jboss ON version 3.3 update 12

       

       

      Log:
