Connecting to Tor¶
Pick a way to connect OnionShare to Tor by clicking the “⚙” icon in the bottom right of the OnionShare window to get to its settings.
Attempt auto-configuration with Tor Browser¶
If you have downloaded the Tor Browser and don’t want two tor
processes running, you can use the tor
process from the Tor Browser.
Keep in mind you need to keep Tor Browser open in the background while you’re using OnionShare for this to work.
Using a system tor
in Windows¶
This is fairly advanced. You’ll need to know how edit plaintext files and do stuff as an administrator.
Download the Tor Windows Expert Bundle from.
Extract the compressed file and copy the extracted folder to C:\Program Files (x86)\
Rename the extracted folder with Data
and Tor
in it to tor-win32
.
Make up a control port password.
(Using 7 words in a sequence like comprised stumble rummage work avenging construct volatile
is a good idea for a password.)
Now open a command prompt (cmd
) as an administrator, and use tor.exe --hash-password
to generate a hash of your password. For example:
cd "C:\Program Files (x86)\tor-win32\Tor"
tor.exe --hash-password "comprised stumble rummage work avenging construct volatile"
The hashed password output is displayed after some warnings (which you can ignore). In the case of the above example, it is 16:00322E903D96DE986058BB9ABDA91E010D7A863768635AC38E213FDBEF
.
Now create a new text file at C:\Program Files (x86)\tor-win32\torrc
and put your hashed password output in it, replacing the HashedControlPassword
with the one you just generated:
ControlPort 9051
HashedControlPassword (the hash you generate from the password you picked above)
In your administrator command prompt, install tor
as a service using the appropriate torrc
file you just created (as described in https://2019.www.torproject.org/docs/faq.html.en#NTService). Like this:
tor.exe --service install -options -f "C:\Program Files (x86)\tor-win32\torrc"
You are now running a system tor
process in Windows!
Open OnionShare and click the “⚙” icon in it.
Under “How should OnionShare connect to Tor?” choose “Connect using control port”, and set
“Control port” to 127.0.0.1
and
“Port” to 9051
.
Under “Tor authentication settings” choose “Password” and set the password to the control port password you picked above.
Click the “Test Connection to Tor” button.
If all goes well, you should see “Connected to the Tor controller”.
Using a system tor
in macOS¶
First, install Homebrew if you don’t already have it, and then install Tor:
brew install tor
Now configure Tor to allow connections from OnionShare:
mkdir -p /usr/local/var/run/tor
chmod 700 /usr/local/var/run/tor
echo 'SOCKSPort 9050' >> /usr/local/etc/tor/torrc
echo 'ControlPort unix:"/usr/local/var/run/tor/control.socket"' >> /usr/local/etc/tor/torrc
And start the system Tor service:
brew services start tor
Open OnionShare and click the “⚙” icon in it.
Under “How should OnionShare connect to Tor?” choose “Connect using socket file”, and
set the socket file to be /usr/local/var/run/tor/control.socket
.
Under “Tor authentication settings” choose “No authentication, or cookie authentication”.
Click the “Test Connection to Tor” button.
If all goes well, you should see “Connected to the Tor controller”.
Using a system tor
in Linux¶
First, install the tor
package. If you’re using Debian, Ubuntu, or a similar Linux distro, It is recommended to use the Tor Project’s official repository.
Next, add your user to the group that runs the tor
process (in the case of Debian and Ubuntu, debian-tor
) and configure OnionShare to connect to your system tor
’s control socket file.
Add your user to the debian-tor
group by running this command (replace username
with your actual username):
sudo usermod -a -G debian-tor username
Reboot your computer.
After it boots up again, open OnionShare and click the “⚙” icon in it.
Under “How should OnionShare connect to Tor?” choose “Connect using socket file”.
Set the socket file to be /var/run/tor/control
.
Under “Tor authentication settings” choose “No authentication, or cookie authentication”.
Click the “Test Connection to Tor” button.
If all goes well, you should see “Connected to the Tor controller”.
Using Tor bridges¶
If your access to the Internet is censored, you can configure OnionShare to connect to the Tor network using Tor bridges. If OnionShare connects to Tor without one, you don’t need to use a bridge.
To configure bridges, click the “⚙” icon in OnionShare.
You can use the built-in obfs4 pluggable transports, the built-in meek_lite (Azure) pluggable transports, or custom bridges, which you can obtain from Tor’s BridgeDB. If you need to use a bridge, try the built-in obfs4 ones first.
