This problem seemed to have been fixed. I just tried a run where I didn't specify the internalhostname on PADS and it still ran. I am not sure when this was fixed. I am using the swift-0.92 binaries I downloaded from the website.<br>

Ok. I have one I wrote up based on what Mihael mentioned. But should we just explain why someone would use the internalhostname key in sites.xml or should we also explain how to tell if you need to set this value and also here is how to find it?<div>

Sure, Jon. The userguide is now kept in the docs/userguide directory of Swift. It's in asciidoc format. Feel free to make changes there, or email me the text and I can add it for you.<br><font color="#888888"><br>David</font><div>

I can write something up and send it to David to add somewhere for the userguide. Not sure where the files for the userguide are kept.<div><div></div><div><br><br><div class="gmail_quote">On Thu, Jun 2, 2011 at 3:08 PM, Michael Wilde <span dir="ltr"><<a href="mailto:wilde@mcs.anl.gov" target="_blank">wilde@mcs.anl.gov</a>></span> wrote:<br>

<br>
We should tell users what they can run on their cluster (eg ping or telnet-style connect tests) to validate the setting of internalHostName.<br>
