Hub
An online server that users connect to, so they can search for, and download files. A public hub is one that has a published address and can be accessed by anyone, while a private hub can only be joined by people who have been invited.
Minimum Share
The combined size of all the files you have in your shared folder must be equal to or greater than this before you can connect to a particular hub.
Connection mode
'Active mode' allows other users to connect to you through your firewall and allows for much faster and broader searches.
'Passive mode' does not allow incoming connections, and may be required for network security reasons. It will result in very slow and restricted searches.
Operator
This is a hub caretaker or moderator who is in charge of running the hub, and controls kicking, banning and user registration etc.
Ban
A forced disconnection from a hub by an operator. Reconnection will not be permitted until the ban has been lifted.
Kick
A temporary disconnection from a hub by an operator. Unlike a ban, you are allowed to reconnect immediately.
File List
A listing of all the files contained within your shared folders.
Download Slot
The number of simultaneous downloads offered by a host. If the person with a file you want has no empty slots, you will not be able to connect to them.
Hashing
A hash value is a unique identifying code which is calculated from the contents of the file itself. This ensures you can always find an alternate source, even if the file names have been changed. There are many different forms of hashing, but Tiger Tree Hashing (TTH) is the type used in DC++.
Rollback checking
If you resume a download, DC++ will check that the beginning of the transfer matches with the end of the incomplete file you already have. This prevents corruption, and ensures the file is the correct one.
Any discrepancy with your Direct Connect download will cause a 'rollback inconsistency', resulting in that source being removed and another one being found.
Search Spam
An excessively high number of search requests sent to a hub within too short a period of time.
Tag
Information about your current Direct Connect download session, which includes client version, connection mode, number of hub connections and upload slots provided.
