DC++ is a popular P2P client. Unfortunately, DC++ client for Linux has many bugs (Russian locale doesn't support for searching and etc.), limits and so not convenient as DC++ for Windows. To run DC++ (windows version) you should install WINE then install DC++ (an install package you can download from DC++ download page).
If you run DC++ through WINE and have found file then try to download it DC++ will failed. For avoiding this behavior you must turn off "Show progress bars for transfers" option in the Settings -> Advanced. Now you can use this client with pleasure.
