<div>Which tests are going purple ? The network tests (conn, smtp, http etc.)<br>or the client-side tests (cpu, disk, memory ...) ?<br><br>Henrik - It is the network test (conn) that went purple for several switches, router, windows servers, a unix server - there was really no consistency in what went purple. I was thinking of using the dns=ip switch for bbtest-net to resolve this - do you think that is a viable solution or would I be better off looking into setting up a caching DNS server on the Hobbit server?

<br><br>If it's the network tests, then the problem is probably that Hobbit is<br>timing out the DNS requests because it takes too long to do the DNS<br>lookups. It probably sends the query first to the server which is down,
<br>and then times out waiting for the response. But that would normally<br>cause your network tests to go red - with a DNS error status - not<br>purple. But setting up a caching DNS server on the Hobbit server might<br>help with that (and is generally a good idea when testing many servers).
<br><br>So I think it's your client-side tests that go purple. Which doesn't<br>really make sense, since the only communication between the clients and<br>Hobbit normally use the IP address directly. But you should check the
<br>BBDISP setting in your clients' etc/hobbitclient.cfg and make sure it is<br>set to the IP of your Hobbit server, not the hostname.<br><br><br>Regards,<br>Henrik<br><br><br>To unsubscribe from the hobbit list, send an e-mail to
