The [http://en.wikipedia.org/wiki/NSLU2 NSLU2] is a [http://en.wikipedia.org/wiki/Linksys Linksys] Network Attached Storage ([http://en.wikipedia.org/wiki/Network-attached_storage NAS]) unit designed to share USB 2 hard disks and flash drives on the network. Provided with a web-interface, its [http://en.wikipedia.org/wiki/Firmware firmware] can be upgraded with [http://www.nslu2-linux.org/wiki/Unslung/HomePage unslung] or [http://www.nslu2-linux.org/wiki/OpenSlug/HomePage openslug], which are small linux distros built specifically for the NSLU2. [http://en.wikipedia.org/wiki/Telnet Telnet], [http://en.wikipedia.org/wiki/Thttpd thttpd] and even [http://en.wikipedia.org/wiki/Openssh OpenSsh] may be installed through its [http://www.nslu2-linux.org/wiki/Optware/Packages OptWare] package manager, although a hard disk installation of the packages is recommended as its [http://en.wikipedia.org/wiki/ROM_image rom] is limited in size. Hence the [http://en.wikipedia.org/wiki/NSLU2 NSLU2] can be converted into a web-server or a media-streamer.

==General guidelines for installing==
*Follow the instructions provided with the NSLU2 package.
*Basically before you turn it on, it's recommended to have all the hard drives and the network previously connected and turned on.
*Also, '''hard drives hot-swapping is not allowed!'''. Flash disks hot-swapping is allowed provided it's done with the '''Flash map''' tool (a utility provided with the [http://en.wikipedia.org/wiki/NSLU2 NSLU2] from [http://en.wikipedia.org/wiki/Linksys Linksys]).

==NSLU2 webinterface==
*login:admin
*pass:admin

==Installing [http://www.nslu2-linux.org/wiki/Unslung/HomePage uNSLUng] [http://en.wikipedia.org/wiki/Firmware firmware]==
NOTE: NO DISKS PLUGGED IN!

#Get the Unslung rom and extract it to a location on your computer.
#Go to the [http://en.wikipedia.org/wiki/NSLU2 NSLU2] web-interface, enter as admin, and click on the upgrade button.
#Then, select your [http://en.wikipedia.org/wiki/Firmware firmware] (i.e. the [http://www.nslu2-linux.org/wiki/Unslung/HomePage unslung] rom) and flash it.
#It should take a few minutes to install, after that the [http://en.wikipedia.org/wiki/NSLU2 NSLU2] reboots and you're set!

The first thing to note is that the web-interface is slightly modified. In particular it has
a [http://en.wikipedia.org/wiki/Telnet telnet] management. Enable [http://en.wikipedia.org/wiki/Telnet telnet], then [http://en.wikipedia.org/wiki/Telnet telnet] to the [http://en.wikipedia.org/wiki/NSLU2 NSLU2] on your network.

==NSLU2 unslung syntax==
===telnet your slug===
Enable telnet if it's not enabled.
> telnet nslu2
login> root
password> uNSLUng
NOTE: with a hard disk installed, the login/password are typically ''admin/admin''.

'''WARNING''': When using [[vim|vi]] with [[putty]] don't press the ''end'' key! It'll freeze the telnet connection.

===reboot your slug===
> reboot

===Finding where are my drives===
> fdisk -l /dev/sda
or
> fdisk -l /dev/sdb

===[[Mount]] a FAT32 drive===
> mkdir /share/hddvfat
> mount -t vfat /dev/sdb5 /share/hddvfat

==Permanent mount of a USB drive==
1. Install Unslung firmware

2. Telnet into NSLU

3. Create mount point /share/hddvfat

4. Create /unslung directory (if does not exist)

5. Create rc.local file in /unslung directory and modify as follows
#! /bin/sh
/bin/mount -t vfat /dev/sdb5 /share/hddvfat > /dev/null
df > /share/hddvfat/df.log
return 1

6. Create rc.samba file in /unslung directory and modify as follows
#!/bin/sh
rm -f /etc/samba/smb.conf
ln -s /opt/etc/smb.conf /etc/samba/smb.conf
rm -f /etc/samba/user_smb.conf
ln -s /opt/etc/user_smb.conf /etc/samba/user_smb.conf
rm -f /etc/samba/smbpasswd
ln -s /opt/etc/smbpasswd /etc/samba/smbpasswd
return 1

7. Create /opt/etc directory (if does not exist)

8. Use smbpasswd -a to create the Samba users you need (skip if you do not want to enable security on your share)

9. Edit /etc/samba/user_smb.conf file as neeeded (at the very least you will need to create a share)
[USB-DRIVE]
comment=FAT32? USB hard drive
path=/share/hddvfat/
public=yes
read only=no
Please note the above share has no security, it is writeable by everyone, to enable security, see www.samba.org

10. Copy /etc/samba/smbpasswd, /etc/samba/smb.conf and /etc/samba/user_smb.conf files to /opt/etc

11. Reboot NSLU (type "reboot" without the quotes and hit enter)
