Rooting

See /shares/Family/tmp/lacie-nas-rooting.txt.

Git

To enable git, we must:

• Enable git logging in /etc/passwd.
• Enable git ssh logging in /etc/ssh/sshd_config

rsync

We do via user git, so:

• Set /bin/bash as shell for user git in /etc/passwd
• Set PermitUserEnvironment yes in /etc/ssh/sshd_config
• Create file /shares/git/.ssh/environment to add rsync into path:

PATH=/opt/bin:/opt/sbin:/bin:/usr/bin:/sbin:/usr/sbin

Startup script

Create the file /opt/etc/init.d/S80config (chmod 755):

#! /bin/sh

# Enable /bin/bash as shell for user git to also allow rsync + git in ssh login
sed -ri '/^git/{s_/home_/shares/git_; s_/bin/false_/bin/bash_}' /etc/passwd
# sed -ri '/^git/{s_/home_/shares/git_; s_/bin/false_/opt/bin/git-shell_}' /etc/passwd

# Change permission for /shares/git or sshd will complain (or add 'StrictModes off to /etc/ssh/ssh_config)
chmod go-w /shares/git

# Configure sshd
if ! grep -q git /etc/ssh/sshd_config; then 
    # Enable ssh login with user git
    sed -ri '/^AllowUsers/s/$/ git/;$aMatch User git' /etc/ssh/sshd_config
    # Enable user environment for user git (in order to set PATH)
    sed -ri $'/^PermitRootLogin/{a PermitUserEnvironment yes\n}' /etc/ssh/sshd_config
    # Restart sshd
    ngc --restart sshd
fi

# Add git to path
if ! grep -q /opt/bin /etc/environment; then echo "PATH=/opt/bin:/opt/sbin" >> /etc/environment; fi

# Add extra addresses to /etc/hosts
if ! grep -q "###hosts.inc###" /etc/hosts; then cat /opt/etc/hosts.inc >> /etc/hosts; fi

Create the hosts include file /opt/etc/hosts.inc:

# ###hosts.inc### additional hosts for lacie-cloudbox

Shares

family

• Mount with

sudo mount //lacie-cloudbox/beq06659 /mnt/any -o noperm,iocharset=utf8,sec=ntlm,username=public,password=

beq06659

• Mount with

sudo mount //lacie-cloudbox/beq06659 /mnt/any -o noperm,iocharset=utf8,sec=ntlm,username=beq06659

Backup

• Backup done with deja-dup, which use duplicity as back-end
• Duplicity can't access samba share. Instead mount samba share locally, and use file:///smb/lacie-cloudbox/sharename instead. Note the triple slash.
• View available backup:

duplicity collection-status file:///smb/lacie-cloudbox/beq06659

• List file in current backup

duplicity list-current-files file:///smb/lacie-cloudbox/beq06659

Metadata information is stored in ~/.cache/duplicity. Attention, it seems this can grow quite large.

DHCP Server

• DHCP daemon configuration: /opt/etc/dhcpd.conf
• View current lease:

cat /opt/etc/dhcpd.leases

To do

• Current backup only includes files that are readable by user beq06659. It should include all files.
• Exclude some unnecessary folders. Organize these folders to ease future backup.
• Backup / filesystem (at least /etc, /usr/local)

Backup solutions

• deja-dup

• Need one setup for each pc
• No centralized management. Backup job could happen all at the same time. Same files between pc are stored multiple times.
• Easy to setup
• How to backup root filesystem?

• duplicity
• backuppc

• How to install?
• Will the NAS have enough memory?

• bacula

• Package readily available in OptWare

• rsnapshot

See question on bacula/backuppc/rsnapshot at http://serverfault.com/questions/282228/bacula-vs-backuppc

Rooting NAS and install new app

• TBC

Troubleshoot

sshd

• See log at /var/log/messages
• Check sshd config /etc/ssh/sshd_config:

• Make sure user is authorized:

 AllowUsers root netbackup git

• If user home is on /shares mount, then disable StrictModes

StrictModes no

• Enable user environment

PermitUserEnvironment yes

then

env > ~/.ssh/environment
vi ~/.ssh/environment                # Remove useless variables

• Edit /etc/passwd:

git:x:503:100:None:/shares/git:/opt/bin/git-shell

• Restart sshd:

ngc --restart sshd

git

• Check that environment is ok [1]

ssh git@lacie-cloudbox  "which git-upload-pack"
