DHT Connected: 0

BitComet BitComet General Discussion
1

I’ve looked for a while online and can’t seem to find a solution for this… My DHT says it’s connected, but it says “DHT Connected: 0” which isn’t helping…

What version of BitComet are you using? I just downloaded it. It’s version 1.30

Do you have a modem? Do you use a router? What make and model are each one of them? Have you forwarded your port? I know this could complicate things, but I’m living in the dorms on a school campus so I’m using their Wi-Fi and don’t know anything about their modems or routers…

What version of Windows, Firewall and Antivirus do you use? I use Windows 7, and I don’t really use any firewalls or antiviruses that I know of.

Is this displayed for as long as you keep BitComet open, or just in the beginning?

This is odd.

Go to the Statistics tab, right-click and choose “Copy All” then paste all the info here.

Yes, it’s been doing this since I opened it. It still works, but it will only connect to like one person at a time and even that doesn’t last for very long. I’ve been torrenting a file for the past 14 hours and it has only downloaded 211 MB…

Here’s the info from the statistics tab:

Hopefully this will help figure out what’s wrong…

DHT needs the UDP port to be open. Can you download anything at all via BitTorrent? Your TCP port seems to be open, I can’t imagine how you could achieve that from a school campus’s WiFi. Go to canyouseeme.org to make sure that information is accurate.

5

Given your situation, you’re almost certainly firewalled and can’t do anything about it. This is common with connections that come with the facility, and includes almost all flavors of wireless connection. I don’t believe you’ll be able to get any DHT connections because your listen port is firewalled. You’ll have to operate in “no listen port” mode, which will be slower but will still work.

Actually his TCP port is open, so as far as BitTorrent connections are concerned he’s not firewalled.

However, if he doesn’t control the router, opening the UDP port will be a problem. Thus DHT won’t work.

I checked canyouseeme.org and none of the common ports they have listed were able to “see” me. neither was port 16065

However, I was able to download a file that is almost 700MB although it did take like 17 hours…

If I do need to operate in “no listen port” mode in order to get a faster download, how would I go about doing that?

“No Listen Port” mode won’t get you a faster download. Rather, it’s a recognition that you cannot get an open port, so no point in BitComet wasting the effort continually trying to do so. Your download is about as fast as it’s going to get, short of changing to a different connection.

You do this by selecting Options → Connection → and setting your listen port to “No Listening Mode”. Choosing this doesn’t really make any difference, it’s just acknowledging what already exists. In that sense the prompt is a little bit misleading, as though you are CHOOSING to be slow, when you don’t really have any choice.
