| = The Transparent Remote File-System Access Method = An alternative to the explicit transfer of files from one machine to another is to attach the remote filesystem to the local machine such that all programs can access it as if it was just another local partition. There are several solutions to this problem, the classical examples are NFS and AFS. At the ETH we are using both of them extensively. Unfortunately NFS has security issues which prevent it from being used in an open environment, and AFS requires special (complex) software on the client side and fundamental changes in the setup of servers. We therefore currently recommend '''Samba''' for remote filesystem attachment. Samba is a free implementation of the Microsoft File Sharing Protocol (SMB). We are running it on all our Unix servers. This enables Windows computers to access files on the Unix machines as if they were on a normal Windows server. Linux is also able to access Samba and mount it just like any other file system. SMB does not encrypt the data it transfers (unlike SSH) but it uses a special method for password authentication which protects the privacy of the password. |

Accessing Samba shares from Linux
Overview
Recent Linux Kernels contain the userspace filesystem FUSE. This allows you to use all sorts of new an inovative ways for mounting remote fileystems with normal user privileges. Samples are the "gnome userspace virtual filesystem" and "sshfs" based on SSH.
All graphical desktop file managers must use FUSE based solutions to access remote SMB/CIFS filesystems because they are running with normal user privileges.
In all cases, the share will be mounted in /run/user/$UID/gvfs/smb-share:server=X,share=Y so that you can also access it on the command line.
As documented in https://computing.ee.ethz.ch/Workstations/FindYourData the share //itet-stor.ee.ethz.ch/<YourAccount> is a good place to find all your accessible CIFS resources. Technical this share is an implementation of a "Distributed File System (DFS)" root for your account. Unfortunately not all desktop file managers can handle this special kind of a share. With the KDE file managers Konqueror and Dolphin you cann't use this share (see
Command Line
gvfs-mount
You can also connect to a Samba share on the command line. After you run that command, you can browse the share in Nautilus.
pmuster@testclient:~> gvfs-mount smb://itet-stor.ee.ethz.ch/pmuster Password required for share pmuster on itet-stor.ee.ethz.ch User [pmuster]: pmuster Domain [WORKGROUP]: d Password: ********
To unmount a share on the command line, just add the -u flag:
pmuster@testclient:~> gvfs-mount -u smb://itet-stor.ee.ethz.ch/pmuster
smbclient
smbclient is something like an interactive shell to the file server and also a good troubleshooting tool for connection problems. To connect your personal DFS root share enter:
pmuster@testclient:~$ smbclient -W d //itet-stor.ee.ethz.ch/pmuster
Enter pmuster's password:

root mount
You can also mount your Samba home area with CIFS. This method is only available on computers where you have root access (i.e. this does not work on Linux workstations managed by us). If the command returns an error message saying "wrong fs type", make sure the package "cifs-utils" is installed.
$ sudo su # mkdir /itet-stor # mount -t cifs -o user=<d\your_tardis_login>,name=itet-stor.ee.ethz.ch \\\\itet-stor.ee.ethz.ch\\<d\your_tardis_login> /itet-stor
Desktop File Managers
Gnome Nautilus
Select on the left side Connect to network and enter the name of the share in the Server Address field, e.g. as 'smb://itet-stor.ee.ethz.ch/pmuster'.
Enter the details as given in the screenshot below.
Nemo
Open the Connect to Server application and enter the details similar to the screenshot below.
KDE Konqueror (all machines at ETH)
Open your Konqueror Filemanager/Webbrowser.
As location, use smb://server/directory followed by <Enter>Type your username and password in the following dialog box.
For accessing your share provided from ID, use the following data:
Location: smb://nas-nethz-users.ethz.ch/share-u-$/username Username: d\yourNethzUsername Password: yourPrivatePassword Obs! The 'share-u-$' part of the location is dependant on the first character in your username. If your username is 'kpelle', this part of the location will change to 'share-k-$'
For accessing your D-ITET share, user the following:
Location: smb://homes.ee.ethz.ch/username Username: d\username Password: yourPrivatePassword
SSH File System
$ mkdir ~/tardis-home $ sshfs <d\your_tardis_login>@login.ee.ethz.ch: ~/tardis-home
But please note, that you can't do sshfs on homes.ee.ethz.ch - use login.ee.ethz.ch instead!
You can also unmount it again by typing:
$ fusermount -u ~/tardis-home
Please note that sshfs is not officially supported by the ISG.EE
