Subject Re: I am abel to ping the machine but still received exception "Could not connect to broker URL"
Date Mon, 23 Jun 2008 17:47:25 GMT


I am suspecting it might be a firewall (based on info in this thread) issue. 
Here are debugging suggestions: 
1. Move broker to the unix m/c with sender app. Can the consumer connect ?
2. If you can do http to the windows m/c - you can, for example, forward
port 80 on your windows machine
   to the broker port 61616 (it is easy to do this on linux, I am assuming
some app like putty can do this on win).   If this checks out, you know it
is firewall issue (your admins may not like this port forwarding beyond
debugging).

 > Is it related to Firewall or so? If that is the case, how come I am able
to "ping" then?
Corporate firewall config  is usually tailored for tcp/udp connections.
