Transmission (BitTorrent client)

Transmission web GUI

Instalasi

Install transmission web gui

sudo apt-get install transmission-cli transmission-common transmission-daemon

Konfigurasi

Setting user permission

Secara default Transmission bekerja dibawah Group “debian-transmission” jadi kita harus memberikan akses group tersebut ke akun user kita, dalam contoh ini user yang digunakan adalah root.

sudo usermod -a -G debian-transmission namauser

Setting Folder Permission

Secara default ketika proses instalasi, Transmission sudah membuat folder untuk lokasi download. Folder terserbut di lokasi /var/lib/transmission-daemon/downloads, Namun, jika kita menginginkan unttuk merubah lokasi folder tersebut ikuti langkah berikut.

Buat folder dan ubah perizinan dan kepemelikian grup nya

mkdir /home/share/public/transmission
chgrp -R debian-transmission /home/share/public/transmission
chmod -R 775 /home/share/public/transmission

Catatan: sesuaikan lokasi folder sesuai keinginan

Pada contoh diatas, kita membuat folder bernama “transmission” pada direktori “home“. Setelah itu kita merubah file ownership menjadi dibawah group “debian-transmission” setelah itu kita memberikan akses baca dan tulis kepada folder tersebut.

Config Seting

Sekarang saatnya kita merubah setting config aplikasi Transmission. Tujuannya adalah untuk memberikan limitasi akses dari web GUI supaya bisa di akses dari luar karena pada settingan awal, Transmission hanya bisa di akses dari localhost (127.0.0.1). Selain itu kita juga bisa memberikan pengamanan seperti akses username dan password, agar tidak semua orang bisa menggunakan torrent client kita. Namun, sebelumnya jangan lupa untuk menghentikan proses Transmission yang sudah berjalan.

sudo service transmission-daemon stop

edit menggunakan teks editor

sudo nano /etc/transmission-daemon/settings.json

Sekarang setelah file config telah terbuka, saatnya menyesuaikan setting dengan keinginan kita. Namun, ada beberapa hal penting yang harus dirubah.

• Download Location

Cari kelimat yang berisi perintah berikut

"download-dir": "/var/lib/transmission-daemon/downloads",

Ganti lokasi tersebut dengan lokasi yang kita inginkan (sudah kita buat diatas) sehingga menjadi

"download-dir": "/home/share/public/transmission",

• RPC Setting

Fungsi RPC adalah memberikan limitasi untuk mengakses dashboard web gui dari transmission kita dengan password dan username. Secara default user yang diberikan adalah “transmission” jika kita ingin merubahnya sesuai dengan keinginan kita maka kita hanya perlu merubah fungsi berikut

"rpc-password": "gantipassword",
"rpc-port": 9091,
"rpc-url": "/transmission/",
"rpc-username": "gantiuser",

Keterangan :

• rpc-password : password yang akan digunakan untuk mengakses transmission web gui
• rpc-port : port yang digunakan untuk mengakses transmission web gui
• rpc-url : rpc url yang akan diberikan ketika kita mengakses web gui (tidak perlu untuk dirubah)
• rpc-username : username yang akan digunakan untuk mengakses transmission web gui

RPC white-list

Untuk bisa memberikan akses dari luar mesin temukan kalimat yang berisi perintah, dan berikan value “true”

"rpc-whitelist-enabled": true,

Dan isikan ip address yang nantinya bisa mengakses ke transmission web

"rpc-whitelist": "127.0.0.1,10.5.*.*",

Atau jika ingin transmission bisa diakses dari semua IP formatnya adalah

"rpc-whitelist": "127.0.0.1,*.*.*.*",

Keterangan:

artinya transmission web bisa diakses dari mesin itu sendiri (localhost), dan mesin yang memiliki ip awalan 10.5.x.x

Finishing & Access Web GUI

jalankan kembali service transmission-daemon

sudo service transmission-daemon start

mengakses transmission web dengan web browser

IPaddress:port/transmission/

10.5.50.25:9091/transmission/
