[solved] Problems to download

Post by foux » 2004-04-14 08:35

Hello, I'm writing a DC client in Java and I have a problem when I try to download a file from a user using DC++ (works fine if the user has dcgui_qt. Here's my complete download procedure (M stands for me, O for other) :

Code: Select all

M->O : $MyNick robert
M->O : $Lock EXTENDEDPROTOCOLDCEDCEDCEDCEDCEDCE Pk=DtCClientv1.0BYFOUXANDWIP
O->M : $MyNick Fanfan
O->M : $Lock EXTENDEDPROTOCOLABCABCABCABCABCABC Pk=DCPLUSPLUS0.181ABCABC
O->M : $Supports BZList
O->M : $Direction Upload 17762
O->M : $Key .....
M->O : $Support BZList
M->O : $Direction Download 3788
M->O : $Key ....
M->O : $Get e:\EasyDivX_082.exe$1

and then, .... nothing happens, I didn't get a $FileLength command, nor than anything else. If I try to get MyList.DcLst instead of a file, everything works perfectly

I hop someone wii be able to help me

you removed | just for this post or do u not send it. ?

Also if thats exact data looks like you are sending 'Support' and not 'Supports'
im not sure that would affect the download in this situation but you may wanna look into that

I have only removed the | on the post, but I'm sending it with my client. I've changes my "$Support" to "$Supports" but unfortunately, it did'nt solve my problem

I've got he same problem in this order. What I don't understand is that I've got no problem de get MyList files, but I can't manage to get other files, dc++ isn't sending me the $FileLength

Id Recommend, use commview or some other packet sniffer and verify what order things are being sent. also change ur Lock/PK and use the same DC++ uses see if that makes a difference..

I've used ethereal to capture the packets sent by dcgui (I'm under linux), I've change my lock and pk, nothings help, the dc++ client still disconnet just after I send the $Get command. I'm kind of stuck here....

ok my last suggestion. Make sure your not getting a $MaxedOut msg because then it will disconnect make sure your testing with people you know have an open slot. because even with no open slot most clients will upload a file list..

No, (unfortunately) I'm not getting a $MaxedOut. If I snif the tcp packets, the client disconnects right after I've send the $Get

Ok, I've solved the problem. In fact, I was oppening a new connection with the client, and the previous one (from the MyList download) was still open, so the client kicks me out.

Thanks all for your help
