How to setup redis for the fuzzer?

[Thelford Williams]

I ran every command in the README.md on Ubuntu 20.04
What url do I use for fuzz/scripts/redis.py? I tried 127.0.0.1:9000 and 127.0.0.1:6379 and neither worked. What is the ID of the server? How do I run the server?

sudo apt-get -y install npm
sudo npm install -g n
sudo n stable
sudo apt install redis-server
sudo apt-get -y install clang-6.0
cd fuzz/scripts
sudo ./prepare.sh
./compile.sh
git clone https://github.com/sslab-gatech/DIE-corpus.git
python3 ./fuzz/scripts/make_initial_corpus.py ./DIE-corpus ./corpus
./fuzz/scripts/populate.sh ~/mujs-fuzzilli/build/release/mujs ./DIE-corpus ch
./fuzz/scripts/run.sh ~/mujs-fuzzilli/build/release/mujs ./DIE-corpus ch

No redis server or tmux connection? Is there a step I missed? If so please add to README.md

redis-cli -p 9000

Have you been able to resolve this issue or find a workaround?

[Jack Ren]

You need a ssh tunnel to proxy the redis port to localhost:9000.
The guidance in README:

./fuzz/scripts/redis.py

[Arvind Kumar]

what should be redis server ID ?
