[JDEV] XDB (external modules)

[Keith Minkler]

yes, but you need to handshake first.. the jabberd server will not just send packets to anyone =]

here is a sample telnet session between me and a base_accept port:

keith at Flint:~$ telnet 24.48.71.2 6669
Trying 24.48.71.2...
Connected to 24.48.71.2.
Escape character is '^]'.
<stream:stream xmlns="jabber:component:accept" to="test" from="test">
<?xml version='1.0'?><stream:stream xmlns:stream='http://etherx.jabber.org/streams' id='3A358CEB' xmlns='jabber:component:accept'>

<handshake>2ea6821f5afdaef01b212fa436a46a01b3cb6001</handshake>
<handshake/>


note that I first send data to the socket..

"test" is what is in my id attribute (i.e. <service id="test"> )

the handshake is created by sha hashing the session id...  (id='3A358CEB') concated with the password (foo in this case).  so in this case i do a SHA-1 hash of 3A358CEBfoo to get 2ea6821f5afdaef01b212fa436a46a01b3cb6001 for my handshake.

the server responds with <handshake/> if i have authed successfully...

at THIS point, your component will start to get packets from jabberd, never before it has authenticated.
