userdel [username]

Updates & Fix Broken Packages

apt-get update
apt-get dist-upgrade

apt-get install --fix-broken
apt-get autoremove
apt-get install ubuntu-desktop

apt-get purge xxx

top

File System Check

fdisk -l

fsck -fyv /dev/sda1 (f=force y=fix)

shutdown -rF now (reboot, forcing fsck on root filesystem)

Mount & Un-Mount Devices

df -h          (show boot partition)
ls /media      (device mounted from GUI)
cat /etc/fstab (partitions and devices that mount on start-up)

mount 

mount /dev/sdb1 /mnt/xxx

umount /dev/sdb1 (sudo)

FSTAB - Mount HDD

mount HDD

sudo mount to see what is mounted
sudo mount -a to mount all entries in fstab

un-mount drive (close apps using drive first)

sudo mkdir /media/sjn8GigMount

sudo fdisk -l or Disk utility to get "Device Name" such as (/dev/sdc1)

gksudo gedit /etc/fstab

select Edit -> Preferences -> Editor
create a backup copy before saving file

Example 1. old-school
[device]    [mount point]     [file system]  [options]      	         [dump] [fsck order]

Network Backup Procedures

Network_backup_wiki.freegeek

Backup a Home Directory

  • date format (e.g. 20121223 for Dec 23 2012)

ssh into backup server

ssh tsbackup@tsbackup
ls /var/tsbackup
ssh -XC tsbackup@tsbackup (.fglan nautilus)
ctrl-c (to back-out)

ssh to tsbackup - nautalus

ssh://tsbackup@tsbackup

rsync from customer box

sudo cp /etc/passwd /etc/shadow /etc/group /home/
dpkg --get-selections > dpkg.out
sudo mv dpkg.out /home/
sudo tar -czf /home/etc.backup.tar.gz /etc/
sudo rsync -avzh /home/ tsbackup@tsbackup:/var/tsbackup/[date-ticketnumber] 2>rsync.log

less rsync.log (view error log)

Note: on the '''data recovery box''' 
      determine mount point of device to backup
      use "fdisk l" or "Disk utility"
      mount /mnt/sdb?

      add /mnt/sdb? in front of /home 
      this avoids the need to chroot.


top

rsync from tsData box

sudo cp /mnt/sdb?/etc/passwd /mnt/sdb?/etc/shadow /mnt/sdb?/etc/group /mnt/sdb?/home/
dpkg --get-selections --admindir=/mnt/sdb?/var/lib/dpkg >dpkg.out
sudo mv dpkg.out /mnt/sdb?/home/

sudo rsync -avzh /mnt/sdb?/home/ tsbackup@tsbackup:/var/tsbackup/[date-ticketnumber] 2>rsync.log

Restore from Backup

sudo rsync -avzh  tsbackup@tsbackup:/var/tsbackup/[date-ticketnumber]/ /home
sudo dpkg --set-selections < /home/dpkg.out
sudo apt-get -u dselect-upgrade

copy (user passwd) hash from original /etc/shadow

Restore User Permissions

  • Create a New User (oem or Bob or Mark) - with Admin. Privileges
Change From: drwxr-xr-x 23 1001 1001 4096 2011-07-07 13:28 oem
