USB Stick Fix for NTFS filesystem on Raspberry Pi

I’ve used USB sticks on the Raspberry Pi before, many times. So I plugged one in for some extra storage. It let me write once and then went into r/o mode. What the hell! Pulled it, plugged it into the PC, no problem. Plugged it into a Windows 7 machine, it complained about drive errors and fixed it. Try again, no luck. So I gave up for a while, it was full of Music that I play through the Sockso Music Server, so no big deal, but I really do want to use it for external storage as the SD card will fill up eventually. Plus I would like to use it as more storage for ftp as well and possibly for Sparkleshare which I intend to install.

One more look

It turns out that at some point while fiddling with the USB drive, I formatted it NTFS. I believe that I tried to format it ext4 and then ext2, neither worked. So I used a WIndows machine to make it NTFS, so it would work.

The issue is that the Rasp Pi does not come with NTFS support out of the box. So I needed to  install ntfsprogs to get it to work OK….

sudo apt-get install nfsprogs

Otherwise it immediately goes to read only. I have not tested but I assume nfsprogs also installs tools to check NTFS file-systems.

To mount my USB stick, I Need to execute …

sudo mount -t ntfs -o rw,uid=erick,gid=erick /dev/sda1 /media/sda/

Symlinks for Sockso Music Server

I have a symlink for music in my Music dir (/home/erick/Music. Set it to, main-collection -> /media/sda/Music/ , in this manner it points to the music collection on the usb stick and Sockso happily finds the music. Sockso does not like spaces in filenames!



Using mount with bind to access usb drive via vsFTP

I have a USB stick plugged into my Raspberry Pi for external storage, mostly to put music on for the Sockso Music Server to get at. But I wanted to use it a bit more for generic storage. FTP is great, you can get to it from any machine and the command line for it is the same on Win or Linux. So I can walk up to any machine, not have to install a thing and reach into a folder with FTP.

For instance, I have an infected Windows Machine, I don’t dare stick a USB stick in it. Instead I go to the command line, ftp to the Raspberry Pi and grab the tools I need from there.

The Issue

The issue was that I tried to symlink from the ftp directory to the USB drive. vsFTP will not follow symlinks for security reasons.

The Solution

Mount the directory you want under the FTP directory using bind. /media/sda is the USB stick mount point and the whole thing gets mounted under the FTP dir using…

sudo mount --bind /media/sda/ /home/ftpuser/usb-drive/

Sockso Music Server on Linux

The Sockso Music Server is very functional and quite easy to set up in standalone or daemon mode. It is cross platform as it only depends on a Java runtime environment being installed on the target computer.

Recently I loaded it on my desktop which runs Lubuntu 14.04. I tested it out on the desktop before loading it onto my Ubuntu  server PC, which holds my music repository.

  • I will outline installing the Java run time environment needed to run Sockso on an Ubuntu machine
  • The Sockso install procedure
  • Getting it to run as a daemon
  • Getting it to find your music
  • At the bottom of the page I will have some links to resources that I followed and will provide information for running Sockso on other platforms.

The Sockso install procedure

It is not so much an install like compiling/installing, apt-get or adding a package. It is a simple old school download and drop files in a directory install.

  1. Download the Sockso zip file.  You can do steps 2 and 3 while waiting for  the download!
  2. Create /usr/share/sockso directory as root or via sudo so all files are set to root:root. ( sudo mkdir /usr/share/sockso )
  3. Create Sockso data directory /var/sockso as root or via sudo. ( sudo mkdir /var/sockso )  If sockso is terminated uncleanly, the files in this directory can get corrupted and it will need to be rebuilt
  4. Extract the files to /usr/share/sockso/ ( sudo unzip sockso-1.5.3.zip -d /usr/share/sockso/ ) I am not 100% on my unzip usage, so this command actually made a sockso-1.5.3 folder under /usr/share/sockso. Then I needed to use sudo mv .. to move all the files and dirs up one level.


Install Java

On my server that runs headless I performed the following after I typed in java on the command line and it told me that it was missing. It usually resides at /usr/bin/java in a Debian/Ubuntu type of file system. If it is installed it will dump out a help file. Using the command which java will also tell you if it is installed…

The program 'java' can be found in the following packages:
 * default-jre
 * gcj-4.6-jre-headless
 * openjdk-6-jre-headless
 * gcj-4.5-jre-headless
 * openjdk-7-jre-headless
Try: sudo apt-get install <selected package>

I went for version 6 headless for starters. I am not sure what the difference between all the versions are, but version 6 worked for me.

…and so on as it installed.

Reading Java Version

If you already have java and want to view the version…

java -version

…will get you the version, such as listed on my desktop PC…

erick@Precision-WorkStation-530-MT:/var/sockso$ java -version
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.14.04.1)
OpenJDK Client VM (build 24.91-b01, mixed mode, sharing)

Test run

Before making it run as a daemon I wanted to test drive it. So the following command will start it up…

sudo sh /usr/share/sockso/linux.sh --nogui --datadir /var/sockso

When you terminate it, try to shut it down clean via a sigterm when you kill the process. I have read that killing it uncleanly can screw up the data directory ( /var/sockso ). Then you have to empty the directory and rebuild it’s contents. I haven’t had it screw up the directory yet.

Running Sockso as a daemon

Running Sockso as a daemon is an advantage when you are running on a server. It will startup when the machine starts and the machine will take care of closing it down cleanly upon shutdown.

Perl script for running sockso as a daemon

After moving the Sockso files to the proper location there will be a Perl file at /usr/share/sockso/scripts/init.d/sockso

Copy the sockso run file written in perl from…





sudo cp /usr/share/sockso/scripts/init.d/sockso /etc/init.d/sockso


Edit the file and change the directory at the top of the file to point to where sockso is installed ( /usr/share/sockso ).

Also make it executable.

sudo nano /etc/init.d/sockso

sudo chmod +x /etc/init.d/sockso

Now that it is in the init.d directory, the following should work…

sockso (start|stop|restart)

Remember to change the directory at the top of the sockso to point to the /usr/share/sockso dir.


Starting Sockso on boot

Follow the Steps 4,5,6 on this blog post…


I have a copy here as a PDF –> sockso-start-on-boot , just in case the link above disappears.


Sockso Command Prompt

Sockso comes with it’s own command prompt to administer it. help will list the commands. You can use the Sockso command line to add music to Sockso’s collections, add and delete users and perform other maintenance to it.

There is also a management webpage where you can perform the same functions as via the command line.

Finding Music

There is a command line mode for sockso where you can point it to certain directories to index music from.

Run sockso to bring up it’s command line. At it;s command line use coladd and then the path to the folder that your music is in to add it. It takes a while to do this, it is indexing it into a database so be patient. You can add multiple directories into it’s collections. If you add music to a directory in the collection, sockso will find it and add it. By default it scans directories in it’s collections every 30 minutes. I’ve tested it and it is pretty cool, dump in some music and a little while later, it’s there like magic.

coladd /home/username/Music

collist will list all the collections. coldel deletes collections.

colscan will force a scan for new collections that have been added.

Symbolic Links to Music Folder

The sockso coladd command has issues with spaces in directory names. What I have done is made a bunch of symbolic links using ln -s directory of music directory-of-music. This makes it easy to see where all the music is and sockso just has to deal with my Music directory and if I add or remove music it will figure it out on it’s own. I show an example below in the Raspberry Pi section.

Sockso on Raspberry Pi

I just ( April 2016 ) installed Sockso on my Raspberry Pi. I got the idea of sticking a USB stick into one of it’s open ports and dump my music repository on it. Them with sockso I can get to it whenever I want. Previously I had it set up on my main server that I have to use Wake on LAN to start up when I am not at home. Having Sockso on the Rasp Pi allows me to get at it instantly and saves energy by not having to run a full fledged server just to play music remotely.

Below is a tree of the Music directory that I created under my home directory. As can be seen there are symlinks without spaces that point to locations on the usb stick, mounted at /media/sda.

erick@raspberrypi ~/Music $ tree -L 1
├── main-collection -> /media/sda/music
└── renee-ipod-music -> /media/sda/Renee's iPod/iTunes_Control/Music/

The USB stick is formatted it’s default way that it came, FAT32. I use pmount /dev/sda1 /media/sda to mount it. In this was it is mounted not as root, it is mounted by my user, so all files are easily accessed by my own user, locally and remotely using NFS or SSHFS. In this way I can add and remove files easily.



In Sockso there is a concept of users. You can have multiple people logged in and have personalized settings. You can even authorize uploads by setting that option.

Adding users at the Sockso command line works similar to adding users in Linux.

useradd NAME PASS EMAIL ISADMIN 1/0     Adds a new user

userlist                                Lists the users
useradd NAME PASS EMAIL ISADMIN 1/0     Adds a new user
userdel ID                              Deletes a user
useradmin ID ISADMIN 1/0                Sets a user to be admin/non-admin
useractive ID ISACTIVE (1/0)            Toggles users between being active or not
coladd PATH                             Adds a folder to the collection
coldel PATH                             Removes a folder from the collection
collist                                 Lists the folders in the collection
colscan DIR (optional)                  Start a collection scan
propset NAME VALUE                      Sets a property
propdel NAME                            Deletes a property
proplist FILTER                         Lists properties
version                                 Show version information
exit                                    Exit Sockso



Where to get Sockso, it’s official site
