Debian

System is a Debian Wheezy
Edit /etc/apt/sources.list and add

deb http://mirrors.kernel.org/debian jessie main                                                                                                                                 
deb http://mirrors.kernel.org/debian sid main                                                                                                                                    

Create /etc/apt/apt.conf.d/00default

APT::Default-Release "stable";                                                                                                                                                   

apt-get update
apt-get install dialog
apt-get dist-upgrade
apt-get install mc screen binutils sshfs pv netcat encfs sudo python man git

What is not available:

• iotop: no I/O accounting support in kernel
• luks: no aes-xts support, don't know for the rest

mail

apt-get install exim4 bsd-mailx

Config: smarthost, no local email / yobi.be / visible domain name: yobi.be / smarthost: smtp.isp.xxx
Complete /etc/email-addresses

backuppc

apt-get install backuppc libfile-rsyncp-perl libio-dirent-perl

Small issue because Apache is not running as the usual www-data but admin user:

chgrp admin /etc/backuppc/*
chgrp admin /usr/lib/backuppc/cgi-bin/index.cgi 
chmod u+s /usr/lib/backuppc/cgi-bin/index.cgi

Set backuppc password:

htpasswd /etc/backuppc/htpasswd backuppc

Move pool to the big partition, preserving hard links

/etc/init.d/backuppc stop
cp -a /var/lib/backuppc /home
rm -rf /var/lib/backuppc
ln -s /home/backuppc /var/lib/backuppc
/etc/init.d/backuppc start

If you want to encrypt backup pool, you can alternatively do:

/etc/init.d/backuppc stop
cp -a /var/lib/backuppc /home/backuppc.orig
rm -rf /var/lib/backuppc
mkdir /home/.backuppc
adduser backuppc fuse
mkdir /var/lib/backuppc
chown backuppc.backuppc /var/lib/backuppc
encfs --public /home/.backuppc /var/lib/backuppc

We need hardlinks, so use "standard" settings of encfs, no external IV chaining!
And because it will be accessed also by Apache, even if through some setuid, we need --public

su -s /bin/bash backuppc
$ rsync -avH /home/backuppc.orig/ /var/lib/backuppc
rm -rf /home/backuppc.orig
/etc/init.d/backuppc start

If you choose encryption, it cannot start automatically anymore:

for i in /etc/rc*.d/S*backuppc; do mv $i ${i/S/K};done
update-rc.d backuppc defaults
systemctl --system daemon-reload

And from now on, use scripts to start/stop manually:

#!/bin/bash
encfs --public /home/.backuppc /var/lib/backuppc && /etc/init.d/backuppc start

#!/bin/bash
/etc/init.d/backuppc stop
fusermount -u /var/lib/backuppc

Visit https://readynas/backuppc
Default backup of localhost /etc will fail due to some read access issues, we can ignore them by tuning the corresponding TarClientCmd and appending to it:

--ignore-failed-read

Transmission

There is a readynas app, but better to use the Debian one if you want to tune it.

apt-get install transmission-daemon
/etc/init.d/transmission-daemon stop

Edit /etc/transmission-daemon/settings.json

"download-dir":...
"incomplete-dir":...
"rpc-password": "your_password", # note that it will be encrypted next time automatically

If you've some transmission settings to transfer from another machine:

• settings.json is in /etc/transmission-daemon/settings.json
• other stuffs (blocklists, resume, torrents,...) go to /var/lib/transmission-daemon/info/

To fix .resume files from another location, here from /shares/.... to /data/....: file is bencoded but a few bash lines are enough

#!/bin/bash
FILE="$1"
OLDDESTSIZE=$(cat "$FILE"|cut -f6 -d:|head -n1|sed 's/destination//')
OLDDEST="/shares"
NEWDEST="/data"
NEWDESTSIZE=$(($OLDDESTSIZE-${#OLDDEST}+${#NEWDEST}))
sed -i "s#:destination[0-9]\+:${OLDDEST}#:destination${NEWDESTSIZE}:${NEWDEST}#" "$FILE"
chown guest:guest "$FILE"

To run it under another user:
Edit /etc/init.d/transmission-daemon -> USER=joe, then:

chown -R joe.users /var/lib/transmission-daemon 
chown -R joe.users /etc/transmission-daemon
systemctl --system daemon-reload
/etc/init.d/transmission-daemon start
