Ok problem solved. The reason why this only appeared on the linux
machines was because a tunnel was not setup correctly from the client
machine to the server machine.<br><br><br><div><hr id="stopSpelling">From: gmr@myyearbook.com<br>Date: Wed, 26 Oct 2011 13:52:22 -0400<br>Subject: Re: [rabbitmq-discuss] AMQP protocol version mismatch problem on linux<br>To: c_showers@hotmail.com<br>CC: rabbitmq-discuss@lists.rabbitmq.com<br><br>I would run tcpdump on the conversation on see if it's actually sending that.

Can someone help me out with this.<br><br>I've been using RabbitMQ locally on my windows box successfully for sometime. But when I try to run on linux with server and client on different linux machines I get this error<br>
<br>AMQP protocol version mismatch; we are version 0-9-1, server sent signature 1,1,0,9<br><br>I am using RabbitMQ version 2.5.1 server and client which supports 0-9-1 but I dont know why the server signature says 1,1,0,9.<br>
<br>To narrow down the problem the java client build I'm running I first ran on Windows and pointed the host to the Linux Rabbit server. And it worked fined when I passed some messages.<br><br>But using the same client build deployed on a Linux box I get the above error. Only when it tries to send a message not on startup. Here is the exact stacktrace<br>
