Hey Geoffrey,
If you try:
DeclareQueue.exe localhost testqueue
do you have any more luck?
Although RabbitMQ is listening to 0.0.0.0 there may be some hostname
resolution issues happening.

[rabbitmq-discuss] no connection
established
13/05/2008 17:53
The rabbitmq server runs, it seems, but no connections are being accepted
by it,
from the java samples or dotnet sample programs or my own programs.
For three days I have been trying everything imaginable to me to get any
client
program to connect to the rabbitmq server. For example I disabled tcpv6 on
my
system and tried all manner of user permissions in the rabbitmq server for
'guest'
and my custom account 'ga' which I gave all same permissions as 'guest'.
The web site asks users to send a note to legitimateconcern at rabbitmq.com if
it takes
more than 2 minutes to connect. Si I have sent a detailed note. There has
been no
response to it.
The web site says Please join our mailing list or send questions to
info at rabbitmq.com. We'd love to hear from you. I've subscribed and sent a
detailed
message to the mailing list. My email did not appear in the mailing list,
and no
responses came back.
Nothing is working thus far, the mailing list, the feedback email, the
rabbitmq
connections. This is my last attempt for anything to happen after which
rabbitmq
must be abandoned for lack of anything working. More than three days of
time is too
much to spend into something and get nothing from it.
To be clear, this message is solely intended as a reflection on my own
inabilities
and oversights, and nothing I am aware of is wrong with rabbitmq.com, the
rabbitmq
server, the documentation, the sample code, the mailing list, all of which
is
graciously offered at no cost, and works for others on the mailing list. I
do not
mean to upset anyone.
My only intent is to ask for a nice person to volunteer their valuable time
to share
information with me that helps the rabbitmq server accept a connection
from any
client program. Java is OK, dotnet is OK, either one as you like, I'll work
with
you. I am a C# 2.0 programmer FWIW. Windows XP-SP2 is the operating
system.
Details to demonstrate the RabbitMQ inability to accept a connection. Maybe
this
info contains some clue to someone smarter than me, I don't know.
1. Server is launched:
C:\>"C:\rabbitmq\erl5.5.5\lib\rabbitmq_server-1.3.0
\sbin\rabbitmq-server.bat"
RabbitMQ 1.3.0 (AMQP 8-0)

2. Java sample program "Tracer" is launched:
C:\rabbitmq\librabbitmq-java-1.3.0>runjava.bat com.rabbitmq.tools.Tracer
Usage: Tracer [<listenport> [<connecthost> [<connectport>]]]
Invoked as: Tracer 5673 localhost 5672
com.rabbitmq.tools.Tracer.WITHHOLD_INBOUND_HEARTBEATS = false
com.rabbitmq.tools.Tracer.WITHHOLD_OUTBOUND_HEARTBEATS = false
com.rabbitmq.tools.Tracer.NO_ASSEMBLE_FRAMES = false
com.rabbitmq.tools.Tracer.NO_DECODE_FRAMES = false
3. Dotnet sample program is launched:
C:\rabbitmq\rabbitmq-dotnet-1.2.8025.1832-net-2.0\bin>DeclareQueue.exe
alpeduez
testqueue
None of the specified endpoints were reachable
Endpoints attempted:
endpoint=amqp-0-9://alpeduez:5672, attempts=1, outcome=AMQP server
protocol
negotiation failure: server version 0-8, t
ransport parameters -1:-1
Stack trace:
at RabbitMQ.Client.ConnectionFactory.CreateConnection(Int32
maxRedirects,
AmqpTcpEndpoint[] endpoints)
at RabbitMQ.Client.ConnectionFactory.CreateConnection(AmqpTcpEndpoint[]
endpoints)
at RabbitMQ.Client.ConnectionFactory.CreateConnection(String address)
at RabbitMQ.Client.Examples.DeclareQueue.Main(String[] args)
4. Go look again to see if Tracer saw any traffic:
C:\rabbitmq\librabbitmq-java-1.3.0>runjava.bat com.rabbitmq.tools.Tracer
Usage: Tracer [<listenport> [<connecthost> [<connectport>]]]
Invoked as: Tracer 5673 localhost 5672
com.rabbitmq.tools.Tracer.WITHHOLD_INBOUND_HEARTBEATS = false
com.rabbitmq.tools.Tracer.WITHHOLD_OUTBOUND_HEARTBEATS = false
com.rabbitmq.tools.Tracer.NO_ASSEMBLE_FRAMES = false
com.rabbitmq.tools.Tracer.NO_DECODE_FRAMES = false
It seems no traffic was detected during the dotnet sample program
execution.
5. Do a netstat command to see if it looks like a server is really
listening.
C:\rabbitmq\rabbitmq-dotnet-1.2.8025.1832-net-2.0\bin>netstat
Active Connections
Proto Local Address Foreign Address State
TCP alpeduez:1800 localhost:4369 ESTABLISHED
TCP alpeduez:4369 localhost:1800 ESTABLISHED
TCP alpeduez:1802 alpeduez:5672 TIME_WAIT
C:\rabbitmq\rabbitmq-dotnet-1.2.8025.1832-net-2.0\bin>
Yes there is something on alpeduez:5672 which is in a TIME_WAIT. Maybe
that's OK,
maybe not. I don't know what a normally working system netstat looks like.
Do you
know what a netstat returns on a working rabbitmq system installation?
6. I run my own C# software and attempt connection to rabbitmq.
No connections are working and the error message talks about endpoints or
protocols.
Sorry I dont remember exactly, my bad. The CreateConnection method on the
factory
is throwing the exception consistently on all input values. I was using
Protocol.GetFromEnviroment and passing in my host name 'alpeduez' to the
CreateConnection method.
7. This is the whole contents of rabbit.log
=INFO REPORT==== 13-May-2008::12:32:09 ===

Settings/ga/rabbitmq/db/rabbit-mnesia/rabbit_persister.LOG" ...

Thank you for any clues or attempts to help me get a connection to
RabbitMQ.
Regards,
Geoffrey
