Remote Shell via AMQ possible ?
I need shell access to a remote, mobile broker/router with dynamic IP
adresses.
On the backend side there is a second broker/router, creating a network of
brokers.
XMPP + Jabber examples only talk to the broker itself, not the OS behind it.
Would it be possible to get a remote shell, using messaging as a transparent
layer ?

Enable the Stomp listener in activemq.xml, fetch your message with a Stomp client (perl, python, ruby, php) and pass it subsequently to ssh.

I don't understand how this could work in an interactive session.
It is not a programmatic approach, it must be an interactive console
as if I'm connecting to a server directly with ssh, but it is transported
over JMS.

See this FAQ
http://camel.apache.org/how-do-i-use-dynamic-uri-in-to.html
But the exec component allows you to define the command to execute as
a header to override the command in the uri configuration, using this
key for the command: ExecBinding.EXEC_COMMAND_EXECUTABLE
And other header for the arguments.

Format of my message:
nagios update test.rrd -t Duration N:714
<route>
<description>RRD processing</description>
<from uri="activemq:queue:LOCAL.RRD.hosta"/>
<recipientList>
<simple>exec:///opt/tools/sysadmin/bin/rrdtool_wrapper.sh?args=${body}</simple>
</recipientList>
</route>
rrdtool_wrapper.sh:
>cat rrdtool_wrapper.sh
#!/bin/sh
args=$*
set $args
user=$1
shift
/bin/su - $user -c "/usr/bin/rrdtool.bin $*"
As a result, the Exec-component will eventually execute
/bin/su - nagios -c "/usr/bin/rrdtool.bin update test.rrd -t Duration N:714"
But as Raoul stated - be careful, as it's very easy to piggy-back commands. A shell-script is in fact not a good idea at all, but it gives you an idea.
Have fun,
Geurt

Hi,
yes, we use Camel / AMQ and honestly I missed the existence of the camel-exec component.
Still impressive to find out the capabilities of Camel !
Security won't be an issue hopefully, as the two brokers talk only via two-way certificate ssl link.
Reading the doc it looks like only predefined commands can be executed.
That will help a little, but may be too inflexible.
I'm behind a full duplex terminal session, running over messages, similar to the Jabber example
in the AMQ book.
Or could I connect to something like:
http://code.google.com/p/xmpp-ssh/downloads/list
<http://code.google.com/p/xmpp-ssh/downloads/list> ?
Preferred client would be stuff like PuTTY. On the other side I don't have a clue what's necessary, but probably you don't get away with what's available on a standard Linux (debian in our case).
Any ideas ?

Hi,
Not sure if you're familiar with Apache Camel [1], but you could create a
simple Camel route that does the following:
1) reads from a JMS queue (using the camel-jms or activemq-camel components)
2) executes the body of the JMS message as a shell command using the
camel-exec [2] component
Probably an interesting project, despite the obvious security concerns such
a mechanism raises ;)
