Raspberry Pi usually runs Linux (raspbian oder raspbmc). Linux allows to mount various external data sources. Following protocols are used commonly: SAMBA: smbfs/cifs, NFS: nfs, SSH: sshfs, FTP: cupsftp and Cloudspace: webdav/davfs. Following article explains with sample config files how to get access to these different datasourecs on the Raspberry Pi.

Following services rsp protocols are described:

1. SAMBA: smb/cifs - Windows protokoll. Should be used locally only
2. NFS: nfs - Unix Protokoll. Requires Unix and is much faster than smb
3. SSH: sshfs - Protokoll which reuired an ssh daemon on the server side
4. FTP: cupsftp - Protokoll which requires an ftp server on the server side
5. Cloudspace: webdav/davfs - Protokoll whis is used by owncloud, seafile and various other applications

Following configuration line have to be added in /etc/fstab and adapted the local environment.

SAMBA

This sample configuration connects to a samba server serverix and directory Serverix and is mounted on /remote/serverix

//serverix/Serverix   /remote/serverix    cifs    noauto,rw,noserverino,credentials=/etc/samba/auth.192.168.0.1.ftpuser    0    0

/etc/samba/auth.192.168.0.1.ftpuser defines the access credentials

username=sambaLogonUserid
password=sambaLogonUseridPassword

NFS

This sample configuration connects to a nfs drive called home on server obelix and will be mounted on /remote/obelix.

obelix:/home        /remote/obelix    nfs    rsize=8192,wsize=8192,intr,noauto,timeo=14    0    0

FTP

This sample configuration connects to a FTP server called www.my-server.de and will be mounted on /remote/server.

curlftpfs#www.my-server.de      /remote/server    fuse noauto,uid=1000,gid=1000,umask=0022,allow_other 0 0

.netrc defines the access credentials

machine www.my-server.de
login myserverFtpLogonUserid
password myserverFtpLogonUseridPassword

SSH

This sample configuration connects to a ssh server called obelix and remote directory /home/pi and will be mounted on /remote/obelix. An id_rsa file generated with ssh-keygen is used for authentication and the public key id_rsa.pub has to be added to the ssh server in the authorized_keys with ssh-copy-id.

sshfs#remoteUser@obelix:/home /remote/obelix     fuse      user,_netdev,reconnect,uid=1000,gid=1000,idmap=user,identityfile=/home/localUser/.ssh/id_rsa,allow_other  0 

CLOUDSPACE/webdav

This sample configuration connects to a server called sd2dav.1und1.de and will be mounted on /remote/1und1.

https://sd2dav.1und1.de        /remote/1und1  davfs   rw,noauto,user  0       0

.davfs2/secrets defines the access credentials

https://sd2dav.1und1.de  serverUserid serverPassword
