Subject: RE: [dsdp-tm-dev] Service Discovery Beta for RSE 1.0 M3Javier 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)
