I will try and investigate that today. Can anyone recommend a front-end to make browsing through the output easier? Is it ethereal/ettercap/wireshark that I should be using? Can you recommend how I can isolate the output to a specific message? Perhaps by process ID or the ability to somehow track the queue ID? Thanks, Alex
