These instructions are very bare, and intended only for my own use.

Preparation

1. Write the disk image to the sd card with dd, using BS=4M.

2. Resize the second partition to ~1.5GiB, create an ext4 partition on the remaining space for media storage.

3. Expand the root partition with e2fsck -f /dev/sdx2 and resize2fs /dev/sdx2.

4. Add an empty file called ssh on the boot partition

5. Start the Pi and ssh in, username pi, password raspberry.

6. Run raspi-config, set the hostname, reboot.

7. Get updates/upgrades.

8. Add smsc95xx.turbo_mode=N to /boot/cmdline.txt (don’t know if still necessary).

Users

1. Run adduser.

2. Use usermod -a -G <comma separated groups> louis to add pi’s groups to new user.

3. Add new user to sudoers.

4. Verify the new user works and can sudo, then disable the pi account with passwd -l pi.

5. Add the extra partition to fstab, on /local using defaults,noatime 0 2.

6. Run addgroup local and adduser louis local.

7. Run chgrp local /local, and mount it.

Network Setup

Edit /etc/network/interfaces to the following:

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0
iface wlan0 inet static
	address 192.168.1.25
	netmask 255.255.255.0
	gateway 192.168.1.1
	wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

and /etc/wpa_supplicant/wpa_supplicant.conf to have

country=NZ
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
	ssid="{SSID HERE}"
	psk="{KEY HERE}"
}

then reboot.

Network bridge setup

1. Add @reboot sleep 60 && /root/wifibridge.sh to root’s crontab.

2. Create a script /root/wifibridge.sh, remembering to chmod +x it. (See source at gist.)

#!/bin/sh
/sbin/ifconfig eth0 10.0.0.1 netmask 255.255.255.0 up
/sbin/iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
echo "1" | /usr/bin/tee /proc/sys/net/ipv4/ip_forward

Transmission setup

1. Make the /local/torrents and /local/torrents/.incomplete directories. Set their groups to local and permissions to 775.

2. Install the transmission-daemon and transmission-cli packages.

3. Add debian-transmission to the group local.

4. Stop the transmission service, and make the following settings changes:

    "cache-size-mb": 32,
    "download-dir": "/local/torrents",
    "download-queue-size": 1,
    "encryption": 0,
    "incomplete-dir": "/local/torrents/.incomplete",
    "incomplete-dir-enabled": true,
    "peer-limit-global": 40,
    "peer-limit-per-torrent": 10,
    "peer-socket-tos": "lowcost",
    "port-forwarding-enabled": true,
    "preallocation": 0,
    "prefetch-enabled": 0,
    "rpc-authentication-required": false,
    "rpc-whitelist": "192.168.1.*",
    "rpc-host-whitelist-enabled": false,
    "umask": 2

Minidlna setup

1. Install minidlna

2. Edit /etc/minidlna.conf with the following settings:

   • media_dir=/local/torrents

   • friendly_name=Pi Torrents

3. Restart the minidlna service, then run service minidlna force-reload.

Samba setup

1. Install samba and create an account with smbpasswd -a <username>.

2. Remove the default share definitions.

3. To create one private share and one public share (think carefully about whether you want this!)

    [Home]
    	path = /home/louis
    	writable = yes
    	valid users = louis

    [PiTorrents]
    	path = /local/torrents
    	security = share
    	browseable = yes
    	writable = yes
    	guest ok = yes
    	guest account = nfsnobody
    	public = yes
    	force user = root
    	force group = root
