A torrent comes from other people's computers, not from one website. That changes what you can trust and what others can see. This page says plainly what GDM does and what it doesn't. The switches it mentions are in Tasks → Torrent settings....
Apa yang dapat dilihat orang lain
- Your IP address. Everyone sharing the same torrent sees it, as do its trackers and the DHT (the network peers use to find each other). That's how BitTorrent works, and no setting in GDM changes it. To hide your address, use a VPN on your whole computer.
- What you download, on your local network. GDM tells other computers on your network which torrents it has, so they can share faster. On public Wi-Fi, turn off Find peers on the local network.
- That you use GDM. Peers see the name "MisterDownloadManager" and its major version, not the exact build.
GDM's torrents don't use encryption (sometimes called "protocol encryption"). That kind of encryption only hides the traffic from simple filters. It never hides who you are, so GDM doesn't claim to offer it. Some peers that require it won't connect.

GDM starts its torrent engine the first time a torrent needs it. With Stop the torrent engine when no torrent is running on (the default), it stops again a minute after no torrent is running or sharing. While it runs, other peers can connect to GDM, and GDM asks your router to forward its port (UPnP). Windows may ask whether to allow GDM through the firewall: allow it on private networks only.
This is the only part of GDM that waits for connections from outside. Downloads, GDM's DNS choice (Options → Connection → DNS), its updates and its helpers only connect out, so they never need a firewall exception; the browser extension and the automation API reach GDM on this computer only (127.0.0.1).
Di Pengaturan torrent, Anda dapat menonaktifkan Terima koneksi masuk dan Petakan port pada router (UPnP), atau DHT. Unduhan tetap berfungsi, tetapi terkadang lebih lambat. Port tetap memastikan aturan firewall dan router tetap berfungsi. Perubahan ini berlaku saat mesin dimulai berikutnya, yaitu saat tidak ada torrent yang berjalan.
The torrent engine is written in Rust, which rules out many memory bugs, and GDM checks every piece against the torrent's fingerprint, so a peer can't slip in altered data. GDM keeps the engine up to date with the fixes its authors publish.

A torrent names the trackers GDM asks for peers. GDM doesn't contact a tracker on your own computer or your local network (127.0.0.1, 192.168.…, localhost and the like), so a torrent can't make GDM send requests into the network it sits in. Add trackers... follows the same rule: it refuses such an address and tells you why, rather than keeping one that would never be asked.
A .torrent file fetched from a web address goes through the same checks as one opened from disk, and GDM reads at most 10 MB of it.
Memblokir alamat
Block the addresses in this list takes the address of a public IP blocklist, in the P2P (PeerGuardian) or eMule .dat format, plain or gzipped. GDM downloads it with its own downloader (your Proxy / Socks settings apply), checks it, and fetches it again every 7 days. Peers in it are refused. A list GDM can't read is left out, and the last good one stays. The engine reads the list when it starts.
File dari torrent
- GDM refuses a torrent with file names your system can't write safely, says which name, and writes nothing.
- GDM never writes into a file that's already there without asking.
- File dari torrent ditandai sebagai diunduh dari internet, seperti file yang diunduh melalui browser. Windows SmartScreen memeriksa program sebelum pertama kali dijalankan, dan Office membuka dokumen dalam Tampilan Terproteksi. Di Mac, Gatekeeper memeriksa aplikasi.
- Torrent dapat berisi apa saja dan siapa pun dapat membuatnya. Buka hanya program dari orang yang Anda percaya, dan pindai program tersebut jika ragu.
Proksi
GDM's Proxy / Socks settings are for web and FTP downloads. Torrents can use a SOCKS5 one too: set a socks5:// proxy in Options → Proxy / Socks and turn on Use the proxy in Torrent settings. The proxy covers connections to peers and web trackers only, so with it GDM turns off the DHT, local peer discovery, incoming connections and UDP trackers; it opens no UDP socket toward the network at all. If the proxy is gone from Proxy / Socks while that switch is on, torrents don't start rather than go around it.
Untuk merutekan semua lalu lintas melalui jaringan lain, gunakan VPN untuk seluruh komputer.
Adaptor jaringan
Options → Proxy / Socks → Network adapter holds GDM's connections to one adapter, usually a VPN's (Options). The torrent engine binds every socket to it: peers (TCP, and through a SOCKS proxy), HTTP and UDP trackers, the DHT and the listening port. On Linux and macOS it binds the adapter itself. On Windows it binds the adapter's address (its IPv4 one when it has one), and Windows sends a packet only through the adapter that has its source address. UPnP and local peer discovery are turned off then, because they talk to the local network rather than through the adapter.
It works as a kill switch. When the adapter disconnects, running torrents stop with "… is not connected; it goes on when it is back", and they start again through the adapter when it is. Until GDM notices (within a second), the engine's sockets are still bound to an address that is gone, so nothing can leave another way. A torrent added while the adapter isn't connected doesn't start, and says why. Tracker names are still looked up by the system's DNS.
