Description

This contribution for SME Server adds the ability to seed or to download SME Server CDROM ISO through the Bit-torrent protocol. Transmission allows users to download files from the Internet and upload their own files or torrents. By grabbing items and adding them to the interface, users can create queues of files to be downloaded and uploaded. Within the file selection menus, users can customise their downloads down to components of individual files. Transmission also seeds—that is, it can re-upload downloaded content.

After adding it to the database updating the configuration file is required:

signal-event yum-modify

Installation For SME8 and SME9

This contrib is currently held in several repositories, so the following commands will install it on your smeserver.

yum --enablerepo=stephdl,GeekeryTransmission install smeserver-transmission

You will then need to activate the database changes etc. The 'official' way is to perform

signal-event post-upgrade;  signal-event reboot

or if you do NOT want to reboot your server

signal-event conf-transmission

Manage settings

There are no panels in the server-manager, the contrib can be managed by the Command Line :

config show transmission

and

config show transmission-daemon

Upgrade Transmission

yum update --enablerepo=stephdl smeserver-transmission transmission

and

signal-event post-upgrade;  signal-event reboot

or if you do NOT want to reboot your server

signal-event conf-transmission

Login to transmission

Transmission is a "web contrib", you need a web browser to handle your torrents. The url to reach transmission is https://sme-ip-or-host/transmission

Just after the installation, only the admin user is allowed to perform a login with its SME Server credentials (on web and samba side), and for matters of security, only on your local network.

	Note:
	All users or groups need to be real users or groups in the server-manager with a password set

Add users

If you want to allow more users to use 'transmission' then execute these commands at the Command Line.

config setprop transmission Transuser user1,user2
signal-event conf-transmission

All users need to be real users in the server-manager with a password set.

Add groups

If you want to allow more groups to use 'transmission' then execute these commands at the Command Line.

config setprop transmission Transgroup group1,group2,group3
signal-event conf-transmission

All groups need to be real groups in the server-manager with a password set.

change the default url

By default transmission is reachable at https://sme-ip-or-host/transmission but if you want to change this

/etc/init.d/transmission-daemon stop
config setprop transmission Name XXXXX
expand-template /var/lib/transmission/settings.json
signal-event conf-transmission

then you need to go to https://sme-ip-or-host/XXXXX

Disable the access (web/samba) to Transmission

If you want to close the access to all your users to the transmission contrib by web or by samba you can perform this. But this do not stop the transmission daemon

config setprop transmission status disabled
signal-event conf-transmission

to restore the ability to use transmission

config setprop transmission status enabled
signal-event conf-transmission

Access global-local-none

By default only IPs which are on your local network are allowed to reach transmission with a web browser, but this behaviour can be changed.

Only IPs on your local network

config setprop transmission PublicAccess local

or All IPs

config setprop transmission PublicAccess global

or No access

config setprop transmission PublicAccess none

After that

signal-event conf-transmission

Change the download folder

By default the download folder is /var/lib/transmission/Downloads

You can change this by a db command, please do not add a "/" at the end of path

/etc/init.d/transmission-daemon stop
config setprop transmission Transdlfolder /opt/toto
mkdir -p /opt/toto
chown -R transmission:transmission /opt/toto
signal-event conf-transmission

Browse your downloads

	Tip:
	Just after the installation, You can browse all your downloads either by samba, or with your browser. Only the admin user is allowed to perform a login with its SME Server credentials, and for matters of security, only on your local network.

You can change these settings with commands below

Through samba

Add users and groups

only the admin is allowed to browse your downloads with samba, if you want to add more users or groups

config setprop transmission Smbusers user1,user2,@group1,@group2
signal-event conf-transmission

In the smb.conf a group is called by "@", do not forget to add it if you want to allow group1 : @group1

Then you can browse all samba shares of your server, find the transmission share and perform a login with your credentials.

Through your web browser

It is a nice feature if you can exchange downloads with your friends outside of your network, of course this could be forbidden in certain countries.

go to https://sme-ip-host/dl-transmission

Listening Port

Transmission is listening in standard on the port 51413 which need to be enabled in the firewall of your network and in your SME Server. Transmission uses the UPNP protocol to allow its port through your network firewall.

Randomize port on launch

In certain case you may want to allow a random port (set between 49152 and 65535). After each Port modifications, you should go to the transmission setting to verify the port is "open"

config setprop transmission-daemon TCPPorts 49152:65535

then in the transmission setting, check the box "randomize port on launch and restart the service

signal-event remoteaccess-update

Set a different port

In certain case you may want to allow a different port (default is 51413). After each Port modifications, you should go to the transmission setting to verify the port is "open"

config setprop transmission-daemon TCPPort 51485

then in the transmission setting, change the port number to be relevant of your db command and restart the service

signal-event remoteaccess-update

If you want that your change comes persistent you have to modify the template /etc/e-smith/templates/var/lib/transmission/settings.json

please see this chapter

Custom Templates

Transmission is a daemon which needs its configuration file named settings.json.

To give easier our life, this configuration file is templated in /etc/e-smith/templates/var/lib/transmission/settings.json.
If you want to make modifications that you cannot change with the web interface of transmission or if you want to give them persistent in case of reconfiguration, you can modify the template.

before you have to stop the transmission-daemon

#  /etc/init.d/transmission-daemon stop
Arrêt de transmission-daemon :                             [  OK  ]

then

nano /etc/e-smith/templates/var/lib/transmission/settings.json 

ctrl+x to save and

signal-event conf-transmission
