| = 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. |

| == The Samba Password == Samba (SMB) uses a fundamentally different way to handle passwords than Unix. This has the advantage that passwords do not cross the net unencrypted, but it has the big disadvantage that we have to maintain a separate password database for Samba. We have setup our system so that the Samba password gets changed at the same time as the unix password. If your samba password does not work, please contact support@ee.ethz.ch . |

Three methods accessing Samba shares from Linux with Gnome (all machines at ETH)
Mountpoint
In all cases, the share will be mounted in /run/user/$UID/gvfs/smb-share:server=X,share=Y so that you can also access it on the command line.
gvfs-mount
You can also connect to a Samba share on the command line. After you run that command, you can browse the share in Nautilus.
mmuster@testclient:~> gvfs-mount smb://homes.ee.ethz.ch/smbtest Password required for share smbtest on homes.ee.ethz.ch User [mmuster]: d\mmuster Domain [WORKGROUP]: d Password: ********
To unmount a share on the command line, just add the -u flag:
mmuster@testclient:~> gvfs-mount -u smb://homes.ee.ethz.ch/smbtest
Nautilus Application
Select on the left side Connect to network and enter the name of the share in the Server Address field, e.g. as 'smb://homes.ee.ethz.ch/smbtest'.
Enter the details as given in the screenshot below.
'Connect to Server' Application
Open the Connect to Server application and enter the details similar to the screenshot below.
Accessing Samba shares from Linux with Konqueror (all machines at ETH)
Open your Konqueror Filemanager/Webbrowser.
As location, use smb://server/directory followed by <Enter>Type your username and password in the following dialog box.
For accessing your share provided from ID, use the following data:
Location: smb://nas-nethz-users.ethz.ch/share-u-$/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
Using CIFS to connect to Samba shares
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 /tardis-home # mount -t cifs -o user=<d\your_tardis_login>,name=homes.ee.ethz.ch \\\\homes.ee.ethz.ch\\<d\your_tardis_login> /tardis-home
Recent Linux Kernels contain the userspace filesystem FUSE. This allows you to use all sorts of new an inovative ways for mounting remote fileystems ... for example you can mount a file system via an ssh connection without needing root privileges:
$ 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
