RE: [dsdp-tm-dev] Service Discovery Beta for RSE 1.0 M3
|
Hi Aaron,
The specification for the Zeroconf protocol
(DNS-SD) can be found in http://files.dns-sd.org/draft-cheshire-dnsext-dns-sd.txt.
In case you want to provide your own
transport or protocol implementation for service discovery, you can
do it through the extension points:
- org.eclipse.tm.discovery.engine.discoveryTransport
- org.eclipse.tm.discovery.engine.discoveryProtocol
I hope it helps,

Javier et all,
Could you direct me to a good
reference for Zeroconf? I have poked around a bit, and trying to read RFC's
and such to figure this stuff out seems like a poor use of time.
I am starting to work on a
design for how to connect the TM to an existing agent on an embedded OS
that has its own proprietary protocol. Over this protocol, which
goes over a single communication link (serial, tcp, whatever), multiple
services may have their own protocols multiplexed on top of it. e.g.
a debugger, profiler, and then other common services such as ftp, tftp,
telnet, etc. I would like to be able to provide an implementation
of whichever RSE components that I need to connect to this system (transport?
and "protocols" for my proprietary/legacy debugging protocol
for instance?) Obviously I would like to reuse all the other stuff
that is planned in TM.
Also, is anyone currently using
LDAP for exploring and configuring a remote system? That seems like
another opportunity for a shared TM component that would benefit many.
Does it already exist?
Any direction is greatly appreciated!
thanks,
Aaron

Subject: [dsdp-tm-dev] Service Discovery Beta for RSE 1.0 M3
Hi all,
I have posted a new version of service discovery for RSE. The new features
are:
- RSE 1.0 M3 compatible (tested with the
CVS of 27/7/2006).
- New protocols and transports can be
added through extension points.
- Service discovery is independent of
RSE (packages org.eclipse.tm.discovery), and has a plugin for linking to
RSE (org.eclipse.rse.discovery)
- The service discovery wizard only shows
supported services (matching any subsystem id). All discovered services
can also be shown as an option.
The provided packages for service discovery are:
org.eclipse.tm.discovery.engine
Engine for the service discovery process
org.eclipse.tm.discovery.protocol
Contains the factory, interface and extension point to define protocols
org.eclipse.tm.discovery.transport
Contains the factory, interface and extension point to define transports
org.eclipse.tm.discovery.protocol..dnssd
Implementation of the DNS - Service Discovery protocol
org.eclipse.tm.discovery.transport.udp
Implementation of the UDP transport
org.eclipse.tm.discovery.view
View to browse discovered services, independent of RSE and enabled to launch
the wizard page to start a new service discovery processes.
org.eclipse.tm.discovery.wizard
Wizard pages for service discovery
org.eclipse.tm.discovery.model
org.eclipse.tm.discovery.mode.edit
EMF model for Service Discovery (requires EMF 2.2.0)
org.eclipse.rse.discovery
Link between RSE and the target management packages.
It extends the extension point org.eclipse.rse.ui.newConnectionWizardDelegate
to provide a customised wizard for the Discovery system type. It
implies that a new systemType "Discovery" has to be created.
Once selected in the first RSE wizard page, it will start the new service
discovery wizard.
At the moment, RSE does not yet accept creating a new host with a list
of services (https://bugs.eclipse.org/bugs/show_bug.cgi?id=150265). Until
this issue is fixed, the service discovery facility of RSE has to be used
through the following workaround:
1- Each service (ftp,telnet...) that wants to be discovered has to be registered
as a systemType
2- The subsystem plugin implementing the service has to have the service
as a supported systemType
3-The id of the subsystem implementing this service has to match the discovered
service (ftp, telnet...)
The service discovery plugins can be found in https://bugs.eclipse.org/bugs/attachment.cgi?id=46888
The list of patches for registering the Discovery systemType as well as
the workaround for ftp and ssh can be found in https://bugs.eclipse.org/bugs/attachment.cgi?id=46889
Please, contact me for any question or feedback about the service discovery
feature, or post your ideas in the bugzilla entry for autodetect (https://bugs.eclipse.org/bugs/show_bug..cgi?id=140320)
