RE: [dsdp-tm-dev] Service Discovery question

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

Hi Mark,

 

Service Discovery is a Framework which can assume different methods

of discovering remote services.

 

The only implementation we have now is using the Zeroconf protocol.

Zeroconf uses UDP broadcasts and requires a server to run on the

remote, which advertises available services. I know that on Fedora

Core 5 and later distributions such a zeroconf server seems to be

typically running; you typically see SSH ports advertised when you

ping the local LAN multicast address.

 

Probing ports specificilly would be a different method of discovery,

but (1) wouldn't allow you to discover the IP on the LAN if you don't

know it and (2) likely wouldn't scale very well if you have many ports

to probe. But it depends on your kind of application, so if you think

that's the right method for you, you can implement service discovery

extensions to have it use such a method.

 

Cheers,

Subject: [dsdp-tm-dev] Service Discovery question

Hi,

I have an service discovery question. If I implement an RSE server on my target device and I have FTP and Telnet servers available what do I need to do to make those services available through RSE and Service Discovery? Do I need to implement a schema and miner to register these services with the server datastore to make them visible through service discovery? Or are FTP and Telnet supported natively?

My use case is that I have an IP address for a device and that's it and I want to be able to discover the services it provides. I would think that unless the FTP and Telnet agents are registered through the DataStore then the service discovery would in effect be a ping on ports 21 and 23 to discover if they are present.

Many thanks,

Mark.
