Using Tor mirrors
Tor is an anonymising software that bounces traffic via computers all around the world. It can provide access to regular sites on the internet or to hidden sites only available on the network.
Using XBPS with Tor
XBPS can be made to connect to mirrors using Tor. These mirrors can be normal mirrors, via exit relays, or, for potentially greater anonymity, hidden service mirrors on the network.
XBPS respects the
SOCKS_PROXY environment variable, which makes it easy to use
Tor can be installed using XBPS:
# xbps-install -S tor
After having installed Tor, you can start it as your own user:
or as a system service:
# ln -s /etc/sv/tor /var/service/
By default, Tor will act as a client and open a SOCKS5 proxy on TCP port 9050 on localhost.
Making XBPS connect via the SOCKS proxy
XBPS reads the
SOCKS_PROXY environment variable and will use any proxy
specified in it. By simply setting the variable to the address and port of the
proxy opened by the Tor client, all XBPS's connections will go over the Tor
An example upgrading your system over Tor:
# export SOCKS_PROXY="socks5://127.0.0.1:9050" # xbps-install -Su
To use a hidden service mirror, the default mirrors need to be overwritten with
configuration files pointing to
.onion-addresses that are used internally on
the Tor network. XBPS allows overriding repository addresses under
Copy your repository files from
/etc/xbps.d and replace
the addresses with that of an onion service (Lysator's onion used as an
# mkdir -p /etc/xbps.d # cp /usr/share/xbps.d/*-repository-*.conf /etc/xbps.d/ # sed -i 's|https://alpha.de.repo.voidlinux.org|http://lysator7eknrfl47rlyxvgeamrv7ucefgrrlhk7rouv3sna25asetwid.onion/pub/voidlinux|g' /etc/xbps.d/*-repository-*.conf
Tor provides layered end-to-end encryption so https is not necessary.
When installing packages, with
SOCKS_PROXY set like the earlier example, XBPS
should indicate that it is synchronising the repositories from the onion address
specified in the override:
# xbps-install -S [*] Updating `http://lysator7eknrfl47rlyxvgeamrv7ucefgrrlhk7rouv3sna25asetwid.onion/pub/voidlinux/current/aarch64/nonfree/aarch64-repodata' ... aarch64-repodata: 4030B [avg rate: 54KB/s] [*] Updating `http://lysator7eknrfl47rlyxvgeamrv7ucefgrrlhk7rouv3sna25asetwid.onion/pub/voidlinux/current/aarch64/aarch64-repodata' ... aarch64-repodata: 1441KB [avg rate: 773KB/s]
It is advisable to set
SOCKS_PROXY automatically in your environment if you
are using an onion. If the setting is missing, a DNS query for the name of the
hidden service will leak to the configured DNS server.
To automatically set the environment variable, add it to a file in
# cat - <<EOF > /etc/profile.d/socksproxy.sh #!/bin/sh export SOCKS_PROXY="socks5://127.0.0.1:9050" EOF
