Subject Re: Wire Format Negotiation Timeout -- Say what??
Date Mon, 13 May 2013 20:31:05 GMT

    Thanks!&nbsp; I'm studying up on tcpdump's man page now (about 30 pages
    of technical details!).&nbsp; Wireshark isn't installed by default, so I
    put in a request to have it installed on Tuesday.&nbsp; I won't be back
    in until Thursday, so I'll resume my diagnostics then. 
    The broker and client are on the same local network, and a
    traceroute takes 1.5 ms for just that one hop!&nbsp; That's a long time.&nbsp;
    Pinging is slow, too, as well as other indications of a slow
    network, possibly.&nbsp; So I think we're barking up the right tree, but
    tracking down the source of any network issues will be an arduous
    task!&nbsp; And then we'll have to fix it if we can find it...

     You can use wireshark (or tcpdump) on the broker
      machine to see if the
      client's WireFormatInfo is coming through and whether the broker
      is sending
      one. Wireshark does have a built in activemq command codec so you
      can see
      the command objects going through. You can also try things like
      ping or
      traceroute to see if the client can get to the broker.
