mptcp-check

A website to check the validity of a mptcp connection

The website is build as a Flask app behind a lighttpd server. Everything is package in a docker container.

installing

you will need to create the too following scripts. I would recommend

start.sh:

#!/bin/bash
email=<YOUR-EMAIL-HERE>
url=test.multipath-tcp.org
path=/var/docker/mptcp-check

docker run --rm --name certbot-init \
            -v "$path/cert:/etc/letsencrypt:rw" \
            -p 80:80 \
            certbot/certbot certonly \
		--force-renewal \
                --non-interactive --agree-tos \
                --email $email \
                -d $url \
                --standalone

docker run --name mptcp-check \
            -v "$path/www:/var/www/:ro" \
            -v "$path/cert/:/etc/letsencrypt/:ro" \
            -p 80:80 -p 443:443 \
            --restart unless-stopped \
            --network host \
            --detach \
            mux514/mptcp-check:main

---

renew.sh

#!/bin/bash
email=<YOUR-EMAIL-HERE>
url=test.multipath-tcp.org
path=/var/docker/mptcp-check

cert-before=$(sha256sum certbot/conf/live/$url/fullchain.pem)

docker run --name certbot-renew \
    -v "$path/www:/var/www/:rw" \
    -v "$path/cert/:/etc/letsencrypt/:rw" \
    --detach \
    certbot/certbot \
    certonly --non-interactive --agree-tos --webroot \
            --webroot-path /var/www/ \
            --email $email \
            -d $url \
            --staging --dry-run

cert-after=$(sha256sum certbot/conf/live/$url/fullchain.pem)

if [ cert-before != cert-after ] then
    docker restart mptcp-check
fi

When the second one has been created, is needs to be added to the crontab and run frequently.

To create the crontab:

crontab -e

write 0 0 * * * root /path/to/renew.sh on a new line

static files

The server will serve all files and folders in the /var/www/files directory. You can use the following command to create dummy random files of various sizes.

mkdir -p /var/docker/mptcp-check/www/files
for i in 1M 10M 100M 1000M; do
    head -c "${i}" /dev/urandom > "/var/docker/mptcp-check/www/files/${i}"
done

updating

run the following commands

docker pull mux514/mptcp-check:main

docker stop mptcp-check
docker rm mptcp-check

then run the start.sh script again.
