I downloaded DC++ today to poke around in it in preparation for the next respawn and holy shit hashing takes a long time. So this post is a warning, do not leave hashing until the last minute! I'll be sharing roughly 1.1 terabytes of 'legit backups' and it's predicting hashing with be done in...75 hours!

Just a word of caution happy.gif

So I was going to make some smart-arse reply to this thread regarding the topic of hashing as it has been thoroughly covered in another thread when to my surprise, said thread has seemed to disappeared. I'm talking about the big long one with the debate on which version of DC++ to use and the whole hashing thing. Something about DC++ and hashing should probably go in Tank's awesome Jumbo Q & A thread if the lords and ladies of Respawn do wish it biggrin.gif

TL;DR Yes we know about hashing. Use version 0.674 or higher plz.

Alioth: We all do not know about hashing.

If I see one person hashing at the event, you owe me pizza. Deal?

The DC++ thread dissapeared for a reason, feel free to discuss the various methods of hashing, but if this thread delves IN ANY WAY into illegal file sharing, i delete it

Well well, it seems poor predictive computing has struck again. After coming home from a night out, I found the hashing complete, only a few hours after I posted. I looked around for a DC++ thread and there are quite a few links to dead forum posts but I couldn't for the life of me find an active post. All in all, hashing takes only a few, about 5ish hours, to do for ~1tb across multiple drives and gogo sticky DC++ topic

Hashing all depends on the speed of your computer. for instance my 1.4tb took about 2 hours, Please use .674 - it hashes, .;750 doesnt and therefore it cant be taken from multiple computers. with hashed files, if someone else has the same file and they are both hashed, dc will download it from both places and give you a faster speed.

I usually just leave dc++ running, so my shares are always hashed

BTW dont share your folder that you are receiving files on, it makes your computer run slow as you will always be hashing.

dc is supposed to remember the hash of the files it downloads

Umm, from my experience with .75 it hashes, it's the builds before .674 that don't

673, which is 674 without an annoying CPU usage bug, is the best version to use, and can get files off people with both 306 era and 0.7xx clients.

If you don't have time to hash, or something breaks, you can use 306, and you only miss out on people with the new clients (But can still leech off people with 673/674)

(0.7xx users can't leech or share with 0.306 and vice versa, but 673/674 does both)

I upgraded to 0.761

I figure most people have worked out by now to pre-hash tongue.gif

Plus it has some nice features, like being able to grab parts of the same linux iso from multiple people biggrin.gif

There are still a lot of people on 306.. so i guess you'll have to outweigh the new features vs. what variety of linux ISOs you want biggrin.gif

Should ban non hashing clients from the hub imo.

Hash or die.

0.401 will also read both styles of file list but won't hash, but I believe it has that CPU usage bug.

To be honest, if anything, we should ban hashing clients. None of the advantages that it gives on the internet are applicable to LANs. I haven't yet seen a single hardcore proponent of hashed-only clients that fully understands why you want to hash in the first place.

If you are trying to get something off a busy sharer, you can often get some of it from someone else. End result is the busy sharers are less busy, spreading the load somewhat.
