Bit Comet

[godsownman]

Hi,

I have been using Bit Comet 0.60 for some time. The other day I was downloading a very rare music file but to my astonishement the total % instead of increasing started decreasing i.e. the total % completed was 25 but after a few minutes when I checked it was at 18.9%. What could be the reason for it to decrease.

As I said it was rare so not many people to download from few peers health is also poor.

Please help

Regards.

I've never experienced this, but I can think of a situation where one or more of blocks of the file received from a peer didn't pass the hash check. So your client will have no choice but to discard the block and redownload it, hopefully from some other peer. Hash checks may fail when line quality is bad at either your or the other peer's end, or when the peer is maliciously feeding cuckoo files to disrupt p2p (read: riaa/mpaa). You can see the amount of bytes discarded in azureus easily but I don't know about bitcomet.
Or is there another explaination for the decrease in file size?

siriusb hit the nail on the head,the p2p client discarded the bits which did'nt pass the hash check and then downloaded the legitimate bits from another peer.Happens quite a while in Shareaza too.

Well, it may be possible, but to verify it, better check the total downloaded list: There must be a figure representing the amount of rubbish data dropped. Hey can you guys tell me whether this rubbish data affects the file downloaded? I got 8mb dropped for downloading 250MB! Also, is there any particular port where you are likely to get better speeds or better connections?

[siriusb]

The rubbish data, displayed as amount of data dropped in most clients, does not affect the downloaded file as the rubbish block is redownloaded. This is possible because BT splits files into many power-of-two-sized blocks (128kB, 256kB, 512KB, etc). So only the offending block is redwonloaded.

Also, is there any particular port where you are likely to get better speeds or better connections?

Certainly. Use a port number outside of the BT default range (6881 - 6889) for better speed and connection. This is because most ISPs block BT ports or else throttle speed on those ports. This is done because BT is responsible for almost 60-70% of the total traffic on the Internet and they hope to reduce their downtimes.

I use BitTornado (for 2 years since my dial up days).., as far as I have noticed, my BitTornado use random ports and my downloads goes upto 32kBps (rest depends on the health of the torrent), and how can we get good speeds outside our ISP's BW restriction?


Anyways, I will try to use other port "outside of the BT default range (6881 - 6889)" and see if I notice anything interesting...

I see that bitcomet uploads alongside downloads. What does it upload though? From which directory?

Yes Bitcommet uploads and downloads at the same time.

I think it uploads what we are downloading.


And


I saw this also the other day. I was downloading a complete album which consisted of many tracks. I gave high priority to a few of my favourite tracks.

They completed and then the problem started.

But after that even after they reached 100% I noticed that it dropped to 99% .... 98 % .....99 % ......like that it even reached 93 % .

On hearing the track it was complete but Bitcommet was still showing it as 97 % complete.

Why did this happen ?

Thank-you

Regards

Dunno man may be some faulty packets but never saw something like that, yes that used to happen lot of times for me on Limeware tho. Bitcomet rox and yes it uploads only those files which r listed in the window and if u delete the task then Bitcomet doesnt or cannot upload anything. So I dl and then task delete thats it
