        Dear Perfsonar support,
      
        
      
      
        I  work with Jisc/UK and we are configuring a network of
        Perfsonar hosts.
      
        
      
      
        The were installed by the STFC/UK admins from the Perfsonar iso.
      
        
      
      
        I have a few questions:
      
        
      
      
        (0) firewall
      
        
      
      
        Is this link correct for firewall configuration
      
        
      
      
        
          
        
        
          Failed to post task: Error getting tools from
              ps03-ban: Connection timed out after 10001 milliseconds

        http://docs.perfsonar.net/manage_security.html
      
        
      
      
        And does the Perfsonar iso leave the firewall configured after
        installation?

Yes, it is automatically configured when using ISO installation and the ports in the table above are correct.

        (1) Is this error a firewall error
      
        
      
      
        
          
        
        
          Failed to post task: Error getting tools from
              ps03-ban: Connection timed out after 10001 milliseconds

This error message is an information that your pscheduler server was unable to get the list of supported tools from the other side.

What does the troubleshoot commands print on you src host:

pscheduler troubleshoot

pscheduler troubleshoot ps03-ban.your_remotehost_domain

pscheduler troubleshoot ps03-management.your_remotehost_domain

        (2) the NICs correctly being used?
      
        
      
      
        Each host has three IPs:
      
         - management
      
         - latency
      
         - bandwidth
      
        
      
      
        when I run
      
         pscheduler task throughput  --source ps00-ban --dest ps99-ban
      
        
      
      
        I see ps00 using the management port in ps99-ban.
      
        
      
      
        Is that expected?
    
    Can you post the whole result?
    
      
        
      
      
        (3) archiver
      
        
      
      
        In each host, there is failure try to contact the archiver
        through management port.
      
    
    Is the archiver central or local to each host?
    
      
      
      
        
      
      
        Again, is that expected?
      
        
      
      
        (4) Error about credentials contacting the archiver
      
        
      
      
        I also see in the logs an error about failed credentials
        contacting the archiver. WOuld it be firewall related?

How do you authenticate your hosts in central MA? Did you follow https://docs.perfsonar.net/multi_ma_install.html#authenticating-measurement-hosts
