PAL (Purdue Air Link) and Computer Labs
1. I'm on PAL, and I can't get on Dtella. Why not?
Purdue changed the way PAL works in the summer of 2011. Please read PAL for more information.
2. I am getting a UDP error on PAL. Is there a way around this?
No. This is related to the previous question.
3. Why can't I get on Dtella on a lab computer? I was able to last year.
Since the upgrade to Windows 7, Dtella no longer works on lab computers due to firewall issues out of our control.
1. Why can't I do this in <insert DC client here>?
Well, there are a lot of DC clients out there (DC++ is the most popular for windows), but we will be able to help you most effectively with DC++. You can download the newest DC++ at http://dcplusplus.sourceforge.net/ . You can also use Shakespeer for Macs and LinuxDC++ for, well, Linux. If you are a new user, please stick with these.
2. What is segmenting? How do I disable it?
As we will tell you in chat, segmenting is when your computer splits a file to download into a bunch of little files and downloads them separately. It's meant to increase speed but doesn't work when you're on a network as fast as ours, and actually slows your download. Also, it theoretically damages hard drives, and definitely slows computers uploading the files.
Most DC clients have the ability to segment. To disable in DC++, go to: file-> settings-> advanced-> Enable segmented downloads. Make sure this box is unchecked, not checked.
1. How does dtella work?
Most people are familiar with programs like Limewire and Kazaa. With these, you connect to everyone else using the program on the internet at the same time. DC++ is somewhat different. With a normal DC++ client, you will connect to a hub. Everyone who connects to this hub can download from each other, just like people on Kazaa can download from each other. The way dtella is different is that it is a hub that is only on Purdue's network. Dtella runs on your computer. DC++ connects to dtella on your computer, dtella connects you to the rest of people on dtella, and you can download. It's a bit complicated, so if it doesn't make sense it isn't important.
2. What does "*** No connection could be made because the target machine actively refused it." mean?
This means that you have to start dtella.exe. To check in windows, push ctrl+alt+del to open the task manager. Click on the processes tab, and dtella.exe should be listed. If it is not running, just open your start menu and click on dtella.exe. Then try connecting again.
3. Such and such port forward suchforth and whatnot.
The most common error people make when setting up dtella seems to be setting ports for DC++ and dtella. Make sure you set the Dtella UDP port with the !UDP command and the DC++ TCP port in your settings. Refer to Dtella:Installation_Guide_for_Windows#Router.2FFirewall_Configuration for instructions on how to do this.
4. I keep getting a "connection timeout". What is that, and how do I fix it?
This either means that you have a port forward issue or your firewall is being stupid. This is usually caused by an improperly forwarded TCP port, which is what is used to transfer files. See question 3 in this section for more help.
5. My downloads stay queued, and never actually start. Why not?
This is most likely caused by the same things in question 4.
6. What should I know about setting up dtella?
Please read Tutorials#Dtella_Tutorials for more information.
Setting up your router
1. How do I set up my router?
Please see Router_Setup_Guide for more information.
2. I already read that and I am still having issues. What should I do?
Please be sure that you followed the guides very carefully. Remember, you have to set two ports: One in dtella with !UDP and one in DC++ in the settings. You have to forward both of these in your router.
1. What do I share?
Do not share anything like your install folder for a game or your Program Files folder. This will get you banned from Dtella. Share something that people might want to use: music, movies, porn, games (the files used for installation). Remember, sharing is caring! The more you share, the more everyone can have. The more everyone can have, the more everyone shares. The more everyone shares, the more you get! Downloading and deleting just hurts you in the end.
2. Who is this person downloading from me? I can't find him on the list of users!
If you are using ApexDC++, you probably have DHT enabled. Please read DHT for more information.
3. I have set up my router and port forwarded properly, but I can't download from people, or I can't even connect. Why is this?
First, please, check your settings again. This sounds stupid, but people actually miss something minor very often in these settings. A few tips here: Check your IP address again. Depending on how your router is set up, you might have a different IP address for your computer now. If this happens, just forward it to the new IP instead. Also, check to see if your TCP port matches the port in settings and the UDP port matches the port Dtella is using.
If these don't work, read the next question.
4. I am having firewall issues. What should I do about this?
If you are in Windows, chances are you are using McAfee Antivirus or Norton Antivirus. Both of these suck. Uninstall whichever one you have and install Avast! Antivirus instead. Not only is it awesome, but it also sounds like a pirate. Get it here. Alternatively, Avira Antivir is also good, but you not only don't sound like a pirate and you are less likely to get support for it from dtella users.
If you still think you need a firewall, Comodo Firewall should be about as secure as you need (hell even Windows Firewall is ok). If you do, make sure you don't install the AV that comes with it and to allow dtella traffic through (easiest to just set the firewall to recognize it as a "trusted" application).
Once you've done this, try to get on dtella. If everthing works, you're all set.
5. I'm getting other errors. What should I do?
Try going here. Dtella:Error_Messages It might help.
6. WTF is this file size error that I'm getting?
Check how your hard drive (or other storage media) is formatted. Chances are that it's FAT32 which has a file size limit of around 4 gigabytes (specifically 1 byte short of 4 GiB). Although FAT32 is nice in that it works on every major operating system, it's not ideal for storing large files. If you intend on pulling files that are 4 GiB or larger, you need to use a more modern file system such as NTFS (Windows), HFS+ (Mac OS), or ext 3/4 (Ok if we had to tell you the last one you shouldn't be using linux). Keep in mind that formatting does erase data.
7. Is XobbleStone24 a guy or a girl? I keep hearing about his/her footlong.
Quite honestly, we have no idea. Ask it yourself.
