Unsling

• Shutdown, remove disk, and restart
• Enable telnet via admin site on NAS: Manage Telnet' -> Enable Telnet
• Connect to NAS via telnet (login: root/uNSLUng)
• Connect disk to port 2 and wait until it's registered on NAS admin site
• In the telnet session, run the unsling command:

  # /sbin/unsling disk2

• When it asks you for a password, enter one (which will become your new root password for telnet sessions)
• Close the telnet session:

  # exit

• Reboot the NAS (keeping the disk connected)
• Confirm success by accessing the NAS admin site -> uNSLUng status: Unslung to disk2, /dev/sda1 message on bottom of screen
• Enable telnet via NAS admin site

Configuration for USB flash drive

• Connect to NAS via telnet (using root and your entered password)
• Make a home folder for root user:

  # mkdir /root

• Inform device we're using flash:

  # touch /.ext3flash

• Close the telnet session and reboot the NAS
• Enable telnet via NAS admin site

ipkg

• From telnet session:

  # ipkg update
  # ipkg install unslung-feeds
  # ipkg update

• Useful tools:

  # ipkg install bash
  # ipkg install nano
  # ipkg install ntpclient

• Run ntpclient daily:

  # echo "5 3 * * * root /opt/bin/ntpclient -s -l -h 0.pool.ntp.org > /var/log/ntp.log && hwclock --systohc --utc" >> /etc/crontab

• You should also comment out the following line in your /etc/crontab file:

  1 * * * * root /usr/sbin/hwclock -s &>/dev/null

• Switch shell:

  # cat /etc/passwd | sed "s/\/bin\/sh$/\/bin\/bash/g" > /root/passwd && cat /root/passwd > /etc/passwd && rm /root/passwd

• Fix environment:

# cd
# echo "export PATH=\"/sbin:/bin:/usr/sbin:/usr/bin:/opt/sbin:/opt/bin\"" > .profile
# echo "export TERM=ansi" >> .profile
# echo "PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] '" >> .profile
# echo "alias ll=\"ls -al\"" >> .profile
