Disable IPv6
|
|
\begin{minted}{sh}
|
|
vim /etc/sysctl.conf
|
|
\end{minted}
|
|
Add:
|
|
\begin{minted}{sh}
|
|
# Disable IPv6
|
|
net.ipv6.conf.all.disable_ipv6 = 1
|
|
net.ipv6.conf.default.disable_ipv6 = 1

|
|
\end{minted}
|
|
\begin{minted}{sh}
|
|
sysctl -p
|
|
\end{minted}
|
|
Add this to kernel boot line /etc/default/grub:
|
|
\begin{minted}{sh}
|
|
GRUB_CMDLINE_LINUX="ipv6.disable=1"
|
|
\end{minted}

then run:

Blacklist the module, don't even load it:
|
|
\begin{minted}{sh}
|
|
echo blacklist ipv6 > /etc/modprobe.d/ipv6.conf
|
|
\end{minted}
|
|
Tell the module not to use IPv6 (hit it with the hammer over and over):
|
|
\begin{minted}{sh}

echo alias net-pf-10 off >> /etc/modprobe.d/aliases.conf
|
|
echo alias ivp6 off >> /etc/modprobe.d/aliases.conf

\subsection{Install nextcloud}
|
|
Copied from Owncloud installation sequence. Todo: review difference to Nextcloud
|
|
|
|
Add Debian Backports (eh?)
|
|
\begin{minted}{sh}
|
|
sh -c "echo 'deb http://mirrors.kernel.org/debian/ jessie-backports
|
|
main' >> /etc/apt/sources.list.d/backports.list"

apt-get dist-upgrade -t jessie-backports
|
|
apt-get clean
|
|
sync
|
|
reboot & exit
|
|
\end{minted}
|
|
Add owncloud repos (ToDo)
|
|
\begin{minted}{sh}
|
|
cd

|
wget -nv \
|
|
https://download.owncloud.org/download/repositories/stable/Debian_8.0/Release.key \

Set up database
|
|
\begin{minted}{sh}
|
|
vim ~/.mysqlpw

\end{minted}
|
|
\begin{minted}{sh}
|

openssl req -new -key pwn.themoes.org.key -out pwn.themoes.org.csr
|

|
|
#** Leave Challenge password and An optional company name blank.
|
|
|
|
# Sent csr to SSL registrar.
|
|
\end{minted}
|
|
Open up port 80 to do SSL registrar verification:
|
|
\begin{minted}{sh}
|
|
vim /etc/iptables.test.rules
|
|
\end{minted}
|
|
Enable the port 80 lines for registar, and port 443 lines for owncloud
|
|
|
|
later at the file
|
|
\begin{minted}{sh}
|
|
iptables-restore < /etc/iptables.test.rules
|
|
iptables -L
|
|
iptables-save > /etc/iptables.up.rules
|
|
\end{minted}
|
|
Copy Gandi file for SSL authentication to /var/www/html/
|
|
|
|
After Gandi verifies it, remove the file.
|
|
|
|
Then disable port 80 in the \gls{firewall} again:
|
|
\begin{minted}{sh}
|
|
vim /etc/iptables.test.rules
|
|
\end{minted}
|
|
\begin{minted}{sh}

iptables-restore < /etc/iptables.test.rules
|
|
iptables -L
|
|
iptables-save > /etc/iptables.up.rules
|
|
\end{minted}
|
|
Move the cert in place
|
|
\begin{minted}{sh}
|
|
mv /home/jebba/certificate-323281.crt /etc/ssl/private/pwn.themoes.org.crt
|

|
|
-out pwn.themoes.org.crt -days 65000
|
|
\end{minted}
|
|
ToDo: consider adding rm pwn.themoes.org.csr
|
|
|
|
Place the .crt and .key files on pwn.themoes.org in /etc/ssl/private
|
|
directory.
|
|
|
|
Make sure the they can't be read by the others.
|
|
|

Configure SSL part of the Apache Server:
|
|
\begin{minted}{sh}

|
|
change to:

\subsection{Spreed}
|
|
\large{Spreed Nextcloud WebRTC}
|
|
|
|
There is a Spreed.me module for Nextcloud, which points to a spreed
|
|
webrtc server. If the spreed and nextcloud server use different
|
|
hostnames (origins), screen-sharing won't be allowed due to browser
|
|
restrictions. So spreed is getting installed straight onto the Nextcloud
|
|
server, https://own.alephobjects.com .
|
|
|
|

|
We're going to use a Docker install... own.alephobjects.com is
|
|
currently running Debian Stretch (testing, version 9). Unfortunately,
|
|
docker.io (as it is named in Debian) is available for jessie-backports
|
|
and sid, but not for stretch... We'll use docker's apt repos to get
|
|
docker....
|
|
\subsection{Install Docker}
|
|
\begin{minted}{sh}
|
|
* https://docs.docker.com/engine/installation/linux/debian/
|
|
\end{minted}
|
|
\begin{minted}{sh}
|
|
apt update
|
|
apt install apt-transport-https ca-certificates gnupg2
|
|
apt-key adv \
|
|
--keyserver hkp://ha.pool.sks-keyservers.net:80 \
|

|
|
vim /etc/apt/sources.list.d/docker.list
|
|
\end{minted}
|
|
Add:
|
|
\begin{minted}{sh}
|
|
deb https://apt.dockerproject.org/repo debian-stretch main
|
|
\end{minted}
|
|
\begin{minted}{sh}
|
|
cd /etc ; git add . ; git commit -a -m 'Add docker repo to apt'
|
|
\end{minted}
|
|
save
|
|
\begin{minted}{sh}
|
|
apt update
|
|
apt install -y docker-engine
|
|
cd /etc ; git add . ; git commit -a -m 'Install docker'
|
|
service docker start
|
|
\end{minted}
|
|
\subsection{Test docker}
|
|
\begin{minted}{sh}
|
|
docker run hello-world
|
|
\end{minted}
|
|
\subsection{Set up spreed docker}
|
|
\begin{minted}{sh}
|
|
mkdir -p /srv/spreed/extra.d
|
|
vim /etc/spreed-webrtc-nextcloud.conf
|
|
\end{minted}
|
|
make config like this:
|
|
\begin{minted}{sh}
|
|
[http]
|
|
basePath = /webrtc/
|
|
|
|
[app]
|
|
authorizeRoomJoin = true
|
|
extra.d = /srv/spreed/extra.d
|
|
|
|
[users]
|
|
enabled = true
|
|
mode = sharedsecret
|
|
\end{minted}
|
|
\subsection{Run Spreed Docker}
|
|
\begin{minted}{sh}
|
|
cd /srv/spreed
|
|
|
|
docker run --name ao-spreed-webrtc -p 8080:8080 -p 8443:8443 \
|
|
-v /srv/spreed -i -t spreed/webrtc -c /etc/spreed-webrtc-nextcloud.conf
|
|
\end{minted}
|
|
|
|
On first launch, it may hang forever because it doesn't have any
|
|
entropy. So it will hang at "Creating new server secrets ..."
|
|
|
|
Here is a workaround to generate entropy:
|
|
|
|
\begin{minted}{sh}
|
|
apt install -y rng-tools
|
|
rngd -f -r /dev/urandom
|
|
\end{minted}
|
|
Run it thusly:
|
|
\begin{minted}{sh}
|
|
docker run -d --name my-spreed-webrtc -p 8080:8080 -p 8443:8443 -v \
|
|
/etc/spreed:/etc/spreed -v /var/log/spreed:/var/log/spreed -v \
|
|
/var/www/owncloud/apps/spreedme/extra:/var/www/owncloud/apps/spreedme/extra \
|
|
-i -t spreed/webrtc -c /etc/spreed/server.conf
|
|
\end{minted}
|
|
\large{Configure Apache}
|
|
|
|

|

\begin{minted}{sh}
|
|

|
|
vim /etc/apache2/sites-enabled/01-own.alephobjects.com.conf
|
|
\end{minted}
|
|
Add this inside the VirtualHost section:
|
|
\begin{minted}{sh}

\subsection{Spreed Configuration}
|
|
\begin{minted}{sh}
|
