[rabbitmq-discuss] AMQP protocol version mismatch problem on linux

Wed Oct 26 21:05:34 BST 2011

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.

I would run tcpdump on the conversation on see if it's actually sending that. Unless you're running a modified RabbitMQ server, that's *very* strange to me.
It seems more likely to me that the client is messing up somehow.

Can someone help me out with this.

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

AMQP protocol version mismatch; we are version 0-9-1, server sent signature 1,1,0,9

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.

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.

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
