Commercial description
LS-WXL : LinkStation™ Duo @ BUFFALO
The LinkStation™ Duo is a high performance, multimedia, shared RAID network storage solution for the home and small office that requires a central location to share data files, photos, video and music.
The unit is a two drive NAS solution that can be configured in RAID 0 for performance or RAID 1 for redundant storage. In addition to the storage capabilities, stream multimedia to a PC, a Mac, a Buffalo™ LinkTheater™ and other DLNA CERTIFIED™ or UPNP media player, as well as sharing movies, photos and documents in a home or small business network via the Internet with the WebAccess feature. The LinkStation™ Duo seamlessly integrates with iTunes® and allows access to music files from your iTunes® software.
With features such as enhanced performance of up to 40MB/s, quick swap via the front panel with two removable drives and easy set-up via a simple web interface, the LinkStation™ Duo is the perfect solution to store, save & share your digital life from one central place.
Gain Root Access
Source / Credit : [1]
Firmware 1.40
Method 1
Follow the instructions in Open Stock Firmware LS-VL, which works for all devices sharing that firmware.
Method 2
Firmware 1.40 has a different sshd_config with 'PermitRootLogin' set to 'no'. The permissions on this file are not open like the pam sshd file, so it is necessary to add a back door prior to upgrading to 1.40. One technique would be to perform the following
echo '* * * * * /bin/bash /tmp/cron.root.sh' >> /etc/cron/crontabs/root
After the firmware upgrade is complete, you can add commands to /tmp/cron.root.sh and they will be executed once a minute with root privileges. You can use this to replace the sshd_config. You may also wish to keep the cron job enabled in case of future issues, though it does pose a security risk.
Firmware prior to 1.40
Tested with firmware v1.33 and v1.34, but does not work with v1.40. It is possible to gain root access via the web server.
1. Create a shared folder name 'www'
2. Enable the web server in Network -> Web Server
3. Set the Port No. 81
4. Set the target folder to www
5. The default index.php is showing phpinfo();
6. Now with PHP enabled, you can edit /etc/pam.d/sshd via a simple script
7. comment out all lines that begin with 'auth'
8. add the line: auth required pam_permit.so
a simple PHP script like :
<?php
$file = '../../../../etc/pam.d/sshd';
$fh=fopen($file, 'w') or die("can't open file");
$stringData = "account required pam_unix.so\n";
fwrite($fh, $stringData);
$stringData = "session required pam_unix.so\n";
fwrite($fh, $stringData);
$stringData = "auth required pam_permit.so\n";
fwrite($fh, $stringData);
fclose($fh);
?>
9. Now, you should be able to SSH to LinkStation Duo without any password.
Note: the file /etc/pam.d/sshd gets re-created each time the system starts up
Best way to get permanent root access is to install your SSH public key in the 'authorized_keys' file.
- mkdir /root/.ssh
- chmod 700 /root/.ssh
... install your SSH public key in /root/.ssh/authorized_keys
- chmod 600 /root/.ssh/authorized_keys
N.B. The ssh-copy-id program, which is distributed with OpenSSH, can also be used to easily copy across your SSH public key onto the LinkStation.
Second method to gain root access
Download acp_commander (See http://buffalo.nas-central.org/index.php/Open_Stock_Firmware)
1. Use acp_commander and the sed command (built-in) to edit the /etc/pam.d/sshd file:
java -jar acp_commander.jar -t <IP_OF_WXL> -ip <IP_OF_WXL> -pw password -c "sed 's/auth/#auth/' </etc/pam.d/sshd >/etc/pam.d/sshd.new"
2. Now add the required auth parameters:
java -jar acp_commander.jar -t <IP_OF_WXL> -ip <IP_OF_WXL> -pw password -c "echo 'auth required pam_permit.so' >>/etc/pam.d/sshd.new"
3. Finally, replace the edited version to the right place:
java -jar acp_commander.jar -t <IP_OF_WXL> -ip <IP_OF_WXL> -pw password -c "cp /etc/pam.d/sshd.new /etc/pam.d/sshd"
NOTE: acp_commander may complain about the password being incorrect but this should not affect the outcome. This second method was tested with firmware v1.34. You could potentially use interactive mode in acp_commander (the -s option) to save keystrokes, but the basic approach is the same.
At this point you should be able to get root access without the need of the password. To maintain root access, the public key recommendation remains as noted above. However, every time the box restarts and /etc/pam.d/sshd is replaced, you could rerun the third command above to regain root access without the password.
IPKG
Once you have root access, you can start to install packages from IPKG. To do so, first run the following
cd /tmp wget http://ipkg.nslu2-linux.org/feeds/optware/cs05q3armel/cross/stable/teraprov2-bootstrap_1.2-7_arm.xsh sh ./teraprov2-bootstrap_1.2-7_arm.xsh
Once that's done, edit /opt/etc/ipkg.conf and add
src cs08q1 http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/stable/ # src cs08q1-unstable http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/unstable/
(If you wish to use the unstable branch you can uncomment it.)
After that just run `ipkg update` and you can then install packages with `ipkg install package`
