Here is the command line to use if you wanna create a torrent:
transmission-create -o /tmp/mnt/PMD/your_futur.torrent -c "your comments here" -t udp://tracker.openbittorrent.com:80 -t udp://open.demonii.com:1337 /tmp/mnt/PMD/your_file_you_wanna_share.zip
Then you need to:
- move your
your_file_you_wanna_share.zip in your transmission download folder
- add the created torrent
your_futur.torrent in your transmission using the web interface by example.
- in transmission web interface, right click on the torrent, and choose "verify local data".
You are set to share your file(s) !
Router is running Tomato by Shibby.
First install Optware (see how to install here steps 1 to 6).
Then install msmtp:
ipkg install msmtp
Edit the configuration file (you may have to install nano "ipkg install nano"):
nano /opt/etc/msmtprc
account default
host smtp.gmail.com
port 587
auth on
user account@gmail.com
password password
auto_from on
from account@gmail.com
tls on
tls_starttls on
#tls_trust_file /opt/etc/ca-certificates.crt
# Use "tls_certcheck off" if you don't have ca-certificates.crt file.
tls_certcheck off
# Log to a separate file; use with no options to disable this feature
# logfile /opt/logs/msmtp
# Uncomment if you want to log to syslog facility, which is disabled by default
syslog LOG_MAIL
Test it:
echo -e "Subject: subject \n\nThis is the body" | msmtp anotheraccount@gmail.com
Done :)
If you use Gmail you might need to allow less secure apps: https://myaccount.google.com/lesssecureapps
Simple SMTP is a simple MTA (Mail Transport Agent) to deliver mail from a computer to a mail hub (SMTP server). It can be usefull to send result of your Cron jobs.
Install ssmtp:
sudo apt-get install ssmtp
Configure it:
sudo nano /etc/ssmtp/ssmtp.conf
#
# Config file for sSMTP sendmail
#
# The person who gets all mail for userids < 1000
# Make this empty to disable rewriting.
root=username@gmail.com
# The place where the mail goes. The actual machine name is required no
# MX records are consulted. Commonly mailhosts are named mail.domain.com
mailhub=smtp.gmail.com:587
# Where will the mail seem to come from?
#rewriteDomain=
# The full hostname
hostname=raspberrypi
UseSTARTTLS=YES
AuthUser=username
AuthPass=password
# Are users allowed to set their own From: address?
# YES - Allow the user to specify their own From: address
# NO - Use the system generated From: address
FromLineOverride=YES
Configure the account sending the email:
sudo nano /etc/ssmtp/revaliases
# sSMTP aliases
#
# Format: local_account:outgoing_address:mailhub
#
# Example: root:your_login@your.domain:mailhub.your.domain[:port]
# where [:port] is an optional port number that defaults to 25.
root:username@gmail.com:smtp.gmail.com:587
pi:username@gmail.com:smtp.gmail.com:587
Try to send an email:
echo "email for test" | ssmtp -vvv email@domaine.com
If you use Gmail you might need to allow less secure apps: https://myaccount.google.com/lesssecureapps
Sometimes, you wanna try some risky things such as playing with Network on your Raspberry through SSH. If you lose the connection, and you are not next to the Raspberry, you lose it for good. Sad but true :(
Timer
A timer to restart Raspberry just in case shit happens while playing dumb through ssh:
sudo nano /home/pi/sshcheck.sh
#!/bin/bash
for (( c=$1; c>1; c-- ))
do
echo -n "Reboot in $c minute(s)... "
date +%H:%M
sleep 1m
done
echo "Reboot in 1 minute(s)..."
sleep 1s
for (( c=59; c>0; c-- ))
do
echo -e "\e[101mReboot in $c second(s)... (CTRL+C to cancel rebooting)\e[49m"
sleep 1s
done
echo -e "\e[101mReboot in $c second(s)...\e[49m"
echo -e "\e[101mREBOOT!!!\e[49m"
sudo reboot
Screen
This needs to be started in a screen. If not, you lose the SSH link, and the timer script is stopped (meaning no restart of Raspberry...).
Here are some screen tips.
- Start a screen :
$ screen
Then start your script within the screen :
$ bash /home/pi/sshcheck.sh number_of_minutes
Once timer is in place, you can detach the screen by doing CTRL + a, then d
- To resume your screen session use the following command :
$ screen -dr
- In case you have multiple screen sessions running on you machine you will need to append the screen session ID after the
r switch. To find the session ID list the current running screen sessions with:
$ screen -ls
There is a screen on:
14704.pts-1.raspberrypi (21/12/18 15:15:26) (Attached)
1 Socket in /run/screen/S-pi.
$ screen -r 10835

Install java:
sudo apt-get install openjdk-8-jre
Download the Subsonic .deb package and install it:
sudo dpkg -i subsonic-x.x.deb
Change user (i have set pi instead of root) :
sudo nano /etc/default/subsonic
For troubleshooting interesting files are here: /var/subsonic
It was interesting because it allowed me to understand why Subsonic web interface was OK but impossible to play a file :
cat /var/subsonic/subsonic.log
[2018-01-14 10:59:44,539] INFO TranscodeInputStream - Starting transcoder: /var/subsonic/transcode/ffmpeg -i /home/pi/Music/Paul Kalkbrenner - Berlin Calling/07_Paul_Kalkbrenner_-_Torted_Original Mix.mp3 -map 0:0 -b:a 128k -v 0 -f mp3 -
[2018-01-14 10:59:44,551] INFO InputStreamReaderThread - (/var/subsonic/transcode/ffmpeg) /var/subsonic/transcode/ffmpeg: 1: /var/subsonic/transcode/ffmpeg: Syntax error: "(" unexpected
It was a problem linked with ffmpeg. I think the problem comes from the fact that ffmpeg given in deb is made for ubuntu/debian but probably not ARM processor. THis is why I install ffmpeg from repository and then linked Subsonic folder to this ffmpeg freshly installed:
sudo apt-get install ffmpeg
sudo rm /var/subsonic/transcode/ffmpeg
sudo ln -s /usr/bin/ffmpeg /var/subsonic/transcode/ffmpeg
Restart Subsonic:
sudo service subsonic restart
Configure Subsonic using web interface and admin account.
It worked! I could play my music from Astana, Kazakhstan while it was actually stocked in my Raspberry in Paris!
In my opinion it works quiet nice! Not laggy I mean.
Install samba:
sudo apt-get install samba
Edit configuration file:
sudo nano /etc/samba/smb.conf
# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
interfaces = 127.0.0.0/8 wlan0
bind interfaces only = yes
[Downloads]
comment = Samba sharing on Raspberry Pi
path = /home/pi/Downloads
writable = yes
guest ok = yes
guest only = yes
create mode = 0777
directory mode = 0777
share modes = yes
Let everyone read and write on /home/pi/Downloads:
sudo chmod -R 777 /home/pi/Downloads
Restart samba:
$ sudo systemctl stop smbd
$ sudo systemctl start smbd
It should be visible in windows Networks.
Install:
sudo apt-get install ddclient
Configure for for two different service with two different website to check IP adress:
sudo nano /etc/ddclient.conf
#
# /etc/ddclient.conf
##
## NOIP.COM
##
protocol=dyndns2
use=web, web=checkip.dyndns.com/, web-skip='Current IP Address: '
server=dynupdate.no-ip.com
login=setyour@mail.com
password=setyourpassword
example.ddns.net
##
## FreeDNS (freedns.afraid.org)
##
protocol=freedns
use=web, web=ifconfig.co/ip,
server=freedns.afraid.org
login=setyourlogin
password=setyourpassword
example.mooo.com
To run ddclient as a daemon, set run_daemon to 'true' in /etc/default/ddclient.
Once it is configured as daemon, restart it:
sudo /etc/init.d/ddclient restart
To debug :
sudo ddclient -daemon=0 -debug -verbose -noquiet (-force)
I only want to have some process owned by specific users to use the VPN. This means two route table, or more.
Routes
Create a new table "42" for marked packet:
sudo ip rule add fwmark 42 table 42
List all route table:
ip rule list
0: from all lookup local
32765: from all fwmark 0x2a lookup 42
32766: from all lookup main
32767: from all lookup default
Delete table 42:
sudo ip rule del fwmark 42 table 42
Show "main" table route:
ip route show table main
default via 192.168.1.1 dev wlan0 src 192.168.1.200 metric 303
10.13.0.81 dev tun0 proto kernel scope link src 10.13.0.82
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.200 metric 303
Add a default route in table 42:
sudo ip route add 0.0.0.0/1 via 10.13.0.29 dev tun0 table 42
Delete the default route in table 42:
sudo ip route del 0.0.0.0/1 via 10.13.0.29 dev tun0 table 42
You can delete all routes of a specific table:
sudo ip route flush table 42
Copy all route from table main to table 42:
ip route show table main | while read LINE; do sudo ip route add $LINE table 42; done
Install transmission:
sudo apt-get install transmission-daemon
Start and stop transmission daemon:
sudo /etc/init.d/transmission-daemon start
sudo /etc/init.d/transmission-daemon stop
Edit configuration of transmission (stop transmission first):
sudo nano /etc/transmission-daemon/settings.json
"incomplete-dir": "/home/pi/Downloads/torrents/.incomplete",
"incomplete-dir-enabled": true,
"rpc-password": "write_it_here",
"rpc-whitelist": "127.0.0.1,192.168.1.*",
"umask": 2,
Check your transmission's IP:
To avoid permission issues:
sudo adduser pi debian-transmission
sudo adduser debian-transmission pi
sudo chmod -R 777 /home/pi/Downloads/torrents
sudo chmod -R 777 /home/pi/Downloads/torrents/.incomplete
Transmission How To
Know your IP address:
Install OpenVPN:
sudo apt-get install openvpn
Know your route before OpenVPN is connected:
route
Copy all necessary conf files in:
/etc/openvpn
Interesting settings:
script-security 2
route-noexec
block-outside-dns
up /etc/openvpn/up.sh
down /etc/openvpn/down.sh
Start openvpn from command line to test if tun0 mounts:
sudo openvpn --config /etc/openvpn/server.conf
ifconfig
To connect to VPN at startup, put conf file in /etc/openvpn. Example: openvpn will connect at startup to VPN1 and VPN2:
/etc/openvpn/vpn1.conf
/etc/openvpn/vpn2.conf
