discover services in pidgin

[nuwan gunarahtna]

Hi All,

I have written a program to publish simple tcp service in avahi daeman.
Here is the relevant code fragment.

[code]
    /*Add the services for IPP */

    if((ret=avahi_entry_group_add_service(group, AVAHI_IF_UNSPEC, AVAHI_PROTO_UNSPEC, 0, name, "_ipp._tcp", NULL, NULL, 651, "test=blah", r, NULL )) < 0)
    {
      if(ret == AVAHI_ERR_COLLISION)
        goto collision;

      perror("Failed to add _ipp._tcp service: \n");
      goto fail;
    }

[/code]


Now I want to see this from pidgin or any chat client.
Is this possible ? If it is how can I do that?

Thanks.

First of all I wouldn't be using _ipp._tcp. IPP is the 'Internet  
Printing Protocol' according to http://www.dns-sd.org/ 
ServiceTypes.html. For Bonjour (Zeroconf) chat you are best off using  
_presence._tcp (see above link for way more info than you need).

So basically if you do what you have above and then open up pidgin  
with a Bonjour account type you should be able to see your  
registration appear (of course you won't be able to chat until you  
implement that part of the Bonjour chat protocol - which you can find  
from the references in the above link).

Thanks Robin. Actually I did know the protocol to use for chat is _presence._tcp.
Now I can see the presence of the service from pidgin.
Ok now I need to build a chat application on this. I went through the link You given. But I could not
find the source that has the Bonjour chat protocol implemented. did you mean this? http://www.dns-sd.org/ClientSetup.html

Actually this is what I want to do now.

I have a P2P overlay network(Dcache ) which is a distributed web cache based on IP multicasting. Any computer in the network can join or leave this P2P network at anytime. Now I want to publish the presence of these nodes which are joining to P2P (This part is done. Now I can publish the presence of nodes and can see those in pidgin)
Then I want to give the chat facility to these nodes in P2P in pidgin.

1)How can I do the next part? If any sources please put here.

2)In order to do that do you tihnk It is neccessary to customise pidgin ?

Or can this be done with no changes to pidgin?

Thanks
