"Little t tor" (Package, linux) not working with bridges

Apologies if I’m in the wrong place, because I am new.

I want to use tor with bridges, so I put my bridges into torrc and started tor with “systemctl start tor”. When I tried to use tor’s SOCKS5 proxy, it doesn’t work.

Upon closer look at tor’s logs, I found this:

May 14 20:42:16 Computer Tor[7708]: Read configuration fil
e "/etc/tor/torrc".
May 14 20:42:16 Computer Tor[7708]: Opening Socks listener

fetches: No running bridges
May 14 20:42:16 Computer Tor[7708]: Signaled readiness 
to systemd

I think the problem is caused by the bridges.
Here is my torrc:

UseBridges 1
ClientTransportPlugin meek_lite,obfs2,obfs3,obfs4,scramblesuit exec /home/user/.local/opt/tor-browser/app/Browser/TorBrowser/Tor/PluggableTransports/lyrebird
ClientTransportPlugin snowflake exec /home/user/.local/opt/tor-browser/app/Browser/TorBrowser/Tor/PluggableTransports/snowflake-client
ClientTransportPlugin webtunnel exec /home/user/.local/opt/tor-browser/app/Browser/TorBrowser/Tor/PluggableTransports/webtunnel-client
ClientTransportPlugin conjure exec /home/user/.local/opt/tor-browser/app/Browser/TorBrowser/Tor/PluggableTransports/conjure-client -registerURL https://registration.refraction.network/api

Bridge webtunnel <IP>:<PORT> <FINGERPRINT> url=<URL> ver=0.0.1

I have internet enabled. I used the bridge files in the Tor Browser.
Please help me, thanks!

It is difficult to connect to the internet in China, let alone tor.

That is sad in China, I’m glad my country doesn’t block access to the Internet.

What’s your tor version and OS?

tor --version

When you start tor, check if tor has the right permission by running:

$ sudo dmesg

and try to find any permission errors (ie, apparmor).

Edit: Check if you have a webtunnel-client.

Here is a guide for Debian-based distros:

  1. Download Tor expert bundle:
$ wget https://archive.torproject.org/tor-package-archive/torbrowser/13.0.15/tor-expert-bundle-linux-x86_64-13.0.15.tar.gz

(Or visit Tor Project | Download Tor for other platforms and versions.)

  1. Extract it:
$ tar -zxvf tor-expert-bundle-linux-x86_64-13.0.15.tar.gz
  1. Move lyrebird to other location:
$ sudo mv tor/pluggable_transports/lyrebird /usr/local/bin
  1. Change the file ownership:
$ sudo chown debian-tor:debian-tor /usr/local/bin/lyrebird
  1. Edit tor AppArmor profile
$ sudo gedit /etc/apparmor.d/system_tor

Include the line below inside this block and save:

  # During startup, tor (as root) tries to open various things such as
  # directories via check_private_dir().  Let it.
  /usr/local/bin/lyrebird ix,
  1. Reload the AppArmor profile:
$ sudo apparmor_parser -r /etc/apparmor.d/system_tor
  1. Edit your torrc:
UseBridges 1
ClientTransportPlugin meek_lite,obfs4,webtunnel exec /opt/lyrebird
Bridge webtunnel your-webtunnel-bridge-line
Log notice file /var/log/tor/notices.log
  1. Start tor
sudo systemctl start tor

It’s Arch Linux. The version of tor is I just installed the lyrebird and the other clients to a folder (/etc/PluggableTransports).

I guess Arch is different from Debian because I do not see a system_tor in the apparmor.d folder.

Yes, it’s different. Do you have a local folder in apparmor.d?

Note that on Arch, user is tor and not debian-tor.

Unfortunately I don’t have an Archlinux machine to test it right now, but you need to add lyrebird to your AppArmor profile.

I do have a local folder in apparmor.d, but there is no AppArmor profile for tor in both the local folder and the apparmor.d folder though.

note: I changed the file ownership as well like you said
