Transmission

Please make yourself aware of the Ultra.cc Fair Usage Policy. Directly pointing any cloud storage directory using Rclone will create extreme strain on your slot's disk and WILL cause a 24-hour ban on accessing your cloud storage repeatedly.

It is YOUR responsibility to ensure usage is within acceptable limits. Ignorance is not an excuse.

If you are on an HDD plan, you should be mindful not to have multiple simultaneous downloads active as it will cause high disk IO utilization, and negatively affect your disk neighbors. There is no set limit on how many active downloads you can have, though depending on the download speeds, we recommend 1-3 at the most. To monitor the disk IO utilization, see this guide.

Transmission is a light-weight BitTorrent client suitable for larger torrent sessions.

Transmission offers the following features:

Encryption
Web interface
Peer exchange
Magnet link support
DHT, µTP, UPnP, and NAT-PMP port forwarding
Webseed support
Watch directories
Tracker editing
Global and per-torrent speed limits

For more information, you can view the complete list of features here.

Transmission is already configured and tuned out of the box. Just install the client, enter your desired password, and press Connect to log in to your Transmission Web Interface.

Go to the Installers tab of your User Control Panel.
Find Transmission in the list and press Install.
Set a strong password.
Wait for the installation to complete.
Go to the Apps tab on the UCP.

Transmissions's config folder: ~/.config/transmission-daemon

Use Transmission Remote GUI

Transmission Remote GUI is a feature-rich cross-platform front-end to control the Transmission daemon via its RPC protocol remotely. It is faster and has more functionality than the built-in Transmission web interface.

Transmission Remote GUI offers the following features:

Native application for Windows, Linux, and macOS
uTorrent-like interface
Select files to download
Choose files priority
View details about connected peers
Full information about each torrent
Per torrent options

You can visit the repository here: https://github.com/transmission-remote-gui/transgui

Installation:

Install the program using the links below. Listed are the direct links to the latest version of the program.

For Windows, you may have to install an additional program; otherwise, upon connection, you will be greeted with the following error message: Unable to load OpenSSL library files: ssleay32.dll and libeay32.dll

To resolve this issue, please see the following: https://support.microsoft.com/en-us/help/4032938/update-for-visual-c-2013-redistributable-package

Creating a New Connection:

Upon your first launch, you should be greeted with a box to input your details, which are as follows:

Remote host: username.servername.usbx.me (servername refers to your server eg, myles)
Port: 443
Use SSL: Checked
Authentication required: Checked
Always Auto-Connect: Checked
Username: Found in your UCP
Password: Found in your UCP
RPC path: /transmission/rpc/web

If you had to backtrack because of SSL Error, you could also go to Manage Connections in the top left corner

If you receive a popup regarding Geo IP, select yes, as this will allow you to see the Peers Country’s location.

Add your first .torrent file

Add a .torrent file to transmission via the remote first click Torrent in the top left of the small GUI, add a torrent. This will open your file explorer for you to add your .torrent file

Add your first Magnet Link

Adding a magnet link is the same. However, instead of adding a torrent file, you choose Add torrent link and paste your link in the dialog box.

Configuration

Enable Public Torrent Seeding (Optional)

Public torrents are stopped after download by default to avoid HDD IO resource abuse and inadvertent usage of upload traffic. You can easily enable public torrent seeding with the instructions given below.
Connect to your Ultra service via SSH.
Execute the following command:

app-transmission restart --remove-pubscript

To enable the script again, execute the following command.

app-transmission restart --add-pubscript

Note that changing the password, repairing or reinstalling the torrent client will disable public torrent seeding again.

Torrent Queueing

If you have an Ultra service with HDD instead of NVME, you need to be mindful of your disk neighbors and not hammer the disk with high IO utilization. See this guide for more information on how to check your disk IO utilization.

One way to mitigate this is to limit the amount of active downloads in your torrent client. Below you will find instructions on how to do this for Transmission.

Connect to your Ultra service via SSH.
Once connected, execute the following command:

app-transmission stop

Then, execute:

nano ~/.config/transmission-daemon/settings.json

Make sure download-queue-enabled is set to true, and set download-queue-size to the desired value.

    "download-queue-enabled": true,
    "download-queue-size": 2,

Once you have edited the values, press Ctrl+x, then y and ENTER to save and exit.
Next, restart Transmission to reload and apply the config file.

app-transmission restart

Auto Unpack Torrents

To automatically unpack multifile .rar torrents, you can create a script that executes upon torrent download completion. Follow the below instructions to create and enable the script for Transmission.

Begin by creating a scripts directory and the script itself.

mkdir -p ~/scripts && touch transmission_unrar.sh

Next, open the script in the nano editor.

nano ~/scripts/transmission_unrar.sh

Paste the following into the script:

Make sure to replace your-username with your specific username from the UCP.

#!/bin/bash
LOG_FILE=/home/your-username/scripts/transmission_unrar.log
SRC_DIR="${TR_TORRENT_DIR}/${TR_TORRENT_NAME}"

echo Extracting $SRC_DIR >> $LOG_FILE

cd $SRC_DIR
unrar e *.rar >> $LOG_FILE

Save and exit the nano editor with Ctrl+x and y, press ENTER to confirm.
Make the script executable with the following command:

chmod +x ~/scripts/transmission_unrar.sh

Next, make sure to stop Transmission from the UCP or by executing the following command:

app-transmission stop

Once Transmission has been stopped, you need to configure Transmission to execute the script at torrent download completion. Open the Transmission settings file in the nano editor:

nano ~/.config/transmission-daemon/settings.json

Ensure you have these settings:

Make sure to replace your-username with your specific username from the UCP

    "script-torrent-done-enabled": true,
    "script-torrent-done-filename": "/home/your-username/scripts/transmission_unrar.sh",

Save and exit the nano editor with Ctrl+x and y, press ENTER to confirm.
Restart Transmission from the UCP or by executing the following command:

app-transmission restart

Download a new torrent that includes a multifile .rar archive.
Check the log to see if it worked:

tail ~/scripts/transmission_unrar.log

Upgrade Transmission v3 to v4

Please note, downgrading of Transmission can be a bit buggy and it should be avoided.

In this section, we will show you how to successfully upgrade your Transmission instance from v3 to v4. Before proceeding with the upgrade, we recommend taking a backup of your Transmission config directory and torrent session state.

First, stop Transmission from the Apps tab on the UCP.
Connect to your Ultra service via SSH.
Execute the following command:

cp -r ~/.config/transmission-daemon ~/.config/transmission-daemon.bak

Next, go back to the UCP and uninstall Transmission. Make sure to let at least one minute pass after Transmission has been uninstalled.
Then, while still on the UCP, go to the Installers tab and reinstall Transmission while choosing version v4.

DO NOT click the Cleanup button, as that will wipe your Transmission config directory and torrent session state. Even though we have previously backed it up, we want to avoid doing this.

Once the installation has been completed, you can proceed with accessing the Transmission Web UI. If successful, your Transmission configuration and torrent session state will be preserved.

Restore Backup

If the Transmission configuration and torrent session state was not successfully preserved after the upgrade. It can be manually restored from the backup that was made pre-upgrade.

First, stop Transmission from the Apps tab on the UCP.
Connect to your Ultra service via SSH.
Execute the following command:

rm -rf ~/.config/transmission-daemon && cp -r ~/.config/transmission-daemon.bak ~/.config/transmission-daemon

Next, restart Transmission by executing app-transmission restart, or go back to the UCP and restart Transmission from the Apps tab.
Access your Transmission Web UI to confirm the backup restoration was successful.
