#Slitheen is a decoy routing system for censorship resistance. The source code consists of two parts: the client code (to be distributed and run on the machines of users wishing to circumvent censorship), and the relay station code (to be run on a relay station deployed by an ISP in the middle of the network).
#If you have any questions about the code or installation, please contact Cecylia Bocovich cbocovic@uwaterloo.ca.
INSTALLTION INSTRUCTIONS:
target=$1 if [ "$target" == "client" ]; then
#For the client:
- The client code consists of two parts: (1) an Overt User Simulator (OUS) that issues repeated requests to uncensored sites, and (2) a SOCKS proxy frontend that takes connection requests and data from the user's browser and feeds it to the OUS.
#0. Building this system requires the following dependencies:
sudo apt-get install build-essential g++ flex bison gperf ruby perl
libsqlite3-dev libfontconfig1-dev libicu-dev libfreetype6 libssl-dev
libpng-dev libjpeg-dev python libx11-dev libxext-dev git
#1. Fetch all necessary git repositories: mkdir client cd client git clone git://git-crysp.uwaterloo.ca/slitheen git clone -b slitheen git://git-crysp.uwaterloo.ca/openssl git clone -b slitheen git://git-crysp.uwaterloo.ca/phantomjs
#2. Build our modified version of openssl
parent_dir=pwd
cd openssl
./config --prefix=$parent_dir/sslout --openssldir=$parent_dir/sslout/openssl
make
make test
make install
cd ..
#3. Build phantomJS (Note: this takes a ridiculously long time) cd phantomjs sed -i "s#sslout#$parent_dir/sslout#g" build.py ./build.py cp bin/phantomjs ../slitheen/client cd ..
#4. Build SOCKS proxy frontend cd slitheen/client make
#5. Run socks and exit to initialize OUS_out pipe ./socks
#6. Obtain public key from relay station save file as pubkey in client/ directory
elif [ "$target" == "relay" ]; then
#For the relay station:
#0. Install dependencies sudo apt-get install libpcap-dev libssl-dev git
#1. Fetch necessary git repository: git clone git://git-crysp.uwaterloo.ca/slitheen git clone -b slitheen git://git-crysp.uwaterloo.ca/openssl
#2. Build our modified version of openssl
parent_dir=pwd
cd openssl
./config --prefix=$parent_dir/sslout --openssldir=$parent_dir/sslout/openssl
make
make test
make install
cp ../sslout/lib/*.a ../slitheen/relay_station
cd ..
#3. Generate public/private key pair cd slitheen/telex-tag-v3 make ./genkeys cp privkey ../relay_station cd ..
#4. Update slitheen.h with correct MAC addresses for client-side and world-side interfaces
If using VM setup, postpone until VM step 10.
#5. Build slitheen proxy cd relay_station make
else echo "Usage: ./INSTALL [client|relay]"

VIRTUAL MACHINE SETUP
If you wish to do a test run on two virtual machines on a single host, follow these instructions
#1. Download an Ubuntu 14.04 .iso (http://releases.ubuntu.com/14.04/)
#2. Create an Ubuntu14.04 virtual machine named "slitheen_client"
#3. Create an Ubuntu14.04 virtual machine named "slitheen_relay"
#4. Install the relay and client onto their respective machines following the
installation instructions below.
#5. Go to the network settings for "slitheen_client" and change Adapter 1 to be
attached to an internal network named "slitheen_net".
#6. In the network settings for "slitheen_relay", enable Adapter 2 and attach
it to the internal network "slitheen_net". Set promiscuous mode to "allow VMs".
#7. With "slitheen_relay" running, go to the network settings, select the adapter
connected to the internal network (eth1), and manually enter the following IPv4 settings:
Address: 192.168.3.1 Netmask:255.255.255.0 Gateway: 0.0.0.0
#8. With "slitheen_client" running, go to the network settings and manually enter
the following IPv4 settings:
Address: 192.168.3.2 Netmask:255.255.255.0 Gateway: 192.168.3.1
#9. Set the DNS server to match the one for eth0 on "slitheen_relay"
#10. In relay station code file slitheen.h, set macaddr to client's MAC address and compile
#11. Restart client and test connection
ping 192.168.3.1
ping 8.8.8.8
