phex message flow
 
hi,
i have a little confusion on the message flow as implemented by phex.
this is what i have observed when i was implementing by own ping -pong in a client that i am developing. as noted earlier, i am using phex in our build environment and i have installed the same in the same machine where i am running my new client.

here i have outlined the steps,
a. i send gnutella connect
b. i receive 200k
c. i send gnutella 200k to phex
d. phex responds me with user-agent phex and a set of headers.
e. i send a ping message .
d. i receive a set of pongs.

now while develping the client i have seen that after the receipt of the message (d), the pong guid that i got is not matching with the ping guid.
i mean after (d), is there any message that is being sent. I can post the output if necessary.

thanks

sorry in the numbering system it should read as a.b.c.d.e.f. by mistake i wrote d in place of f. however in the post that i referred is correct , i mean the step 4

Please don't highjack another persons thread with something that is way off topic....
Besides that do you even use Phex ??
You have been answered in the limewire forum where you also posted the same question...

Could you add the headers being sent?

Alcherenga February 3rd, 2008 11:24 AM

arne, i have the headers written to a binary file in disk for experimental parsing. where do i post or upload that? can u name any site where it could be uploaded.

however, i think, this is the problem that i am facing. when i get connected to the phex ultrapeer which is also connected to other clients and ultrapeers, before it sends the pong message, i receive a set of query messages. i parsed the headers and found that message type is 0x80, and hence it must be the query message.

this was not always the case and the flaw was in my experimental code, i think.

but one thing that i would like to bring to ur notice is that, phex is sending me more than 20 pongs for a single ping. is it a good idea to send so much of pongs. { i mean going by the spec, it should return 10 pongs} and the messages are broken. that is receive the header and then the pong message.

i think, my problem is solved now, and i could sucessfully parse query and pong messages. the next thing, that i have to look for is query hit, bye and push.

thanks a lot....

You should get one pong for the node itself and max 6 additional pongs from the pong cache for each additional hop your ping message would travel.
So max. 7 pongs each with the MsgId of the Pong you send.

Otherwise these pongs are likely not originating from Phex, just routed through Phex.

Of course there could also be a bug somewhere, but that would require more details from you. Message dumps and if possible test cases...
