Samba is a Linux server that provides remote filesystem access using SMB/CIFS protocol and is most commonly used by UFRC clients for drive mapping to HiPerGator filesystems from their Microsoft Windows, MacOS, and Linux desktops.

Notice: Samba access is only available while on the University of Florida network. You must be on campus or connected to the UF VPN to mount HiPerGator filesystems as network drive shares.

The network drive server name for /blue and /orange is exasmb.rc.ufl.edu

The network drive server name for /home is cifs.rc.ufl.edu.

Mapping Drive Shares

Note: for automatically mounted filesystem paths like /blue/group or /orange/project use the full path when mounting a samba share to initiate the automounting. e.g. on Windows type the full path into the Windows Explorer Path bar - '\\exasmb.rc.ufl.edu\blue\mygroup\mydir'.

Windows

Expand this section to view instructions for accessing with Windows.

Open "This PC", then click on the "Computer" tab and select "Map network drive".

If you are logged into a managed device with UFAD credentials enter the following into the search field in the Start Menu or the Windows Explorer location bar and browse the available folders.

```
\\exasmb.rc.ufl.edu
```

For /home, the server name is :

```
\\cifs.rc.ufl.edu
```

You cannot browse the home area. You MUST enter the full path to your home share: \\cifs.rc.ufl.edu\home\<username> If you are not logged with UFAD credentials i.e. are using a local Windows account or some such a login box will appear for a username and password. Enter your UFAD credentials to be connected to the system. Precede your username with "UFAD\".

For example, user "jsmith" would enter the following username
```
 UFAD\jsmith
```

Note: If contents of the Samba folders change after the connection is established, you may need to click on the refresh button in Windows Explorer or press 'F5' to see the changes.

MacOS X

Expand this section to view instructions for accessing with Mac.

Bring the Finder to the front
Select "Connect to Server..." from the "Go" menu or press Command+K
Enter smb://exasmb.rc.ufl.edu
Click "+" button to add to favorites (optional)
Connect (use GatorLink user name and password)

Note: There is a known issue with the CIFS client in Mac Finder. The Finder software in current version of MacOS does not have a refresh button to update contents for any changes after the connection is established and disconnecting/reconnecting does not refresh CIFS contents either. A manual solution to force refreshing in Mac Finder can be found on the web [1], [2].

Linux

Expand this section to view instructions for accessing with Linux.

GNOME Desktop

Click on a "Places" Menu at the top-left corner of the screen. Select the "Connect to Server..." option to open a dialog where you can select the service type, server, etc. Fill out the dialog as shown below:

Service type: Windows Share
Server: exasmb.rc.ufl.edu
Share: blue for /blue, homes for /home, or orange for /orange filesystem
Domain: UFAD
Username: your Gatorlink user name
Password: your Gatorlink password

Command Line

To mount from the Linux shell prompt, install the cifs-utils package (yum or apt-get) and run

sudo mount -t cifs -v -o user=<GatorLink Username>,domain=ufad,sec=ntlmssp <remote share>/<group> <local mount point>

where <GatorLink Username> is your GatorLink username, <remote share> is the remote folder you wish to mount, <group> is the group directory you wish to access, and <local mount point> is the local directory on which to mount the remote share (i.e. directory). For '/home', <remote share> will be //cifs.rc.ufl.edu/home.

You will be asked to enter your Gatorlink password.

Research Computing only supports SMB versions >3.0.

Examples

/blue

mount -t cifs -v -o user=joe.smith,domain=ufad,sec=ntlmssp //exasmb.rc.ufl.edu/blue/smith /mnt/blue/smith

/orange

mount -t cifs -v -o user=joe.smith,domain=ufad,sec=ntlmssp //exasmb.rc.ufl.edu/orange/smith /mnt/orange/smith

/home

mount -t cifs -v -o user=joe.smith,domain=ufad,sec=ntlmssp //cifs.rc.ufl.edu/home/jsmith /mnt/home

-==Connecting to the Samba server==
+[[Category:Storage]][[Category:Transfer Data]]
-The UF HPC Center has a samba server located at samba.hpc.ufl.edu.
+__NOTOC__
+Samba is a Linux server that provides remote filesystem access using SMB/CIFS protocol and is most commonly used by UFRC clients for drive mapping to HiPerGator filesystems from their Microsoft Windows, MacOS, and Linux desktops.
-In order to connect to it, you can do one of the following:
+'''Notice:''' Samba access is only available while on the University of Florida network. You must be on campus or connected to the [http://vpn.ufl.edu UF VPN] to mount HiPerGator filesystems as network drive shares.
-* To simply connect to the shares there, you can click on your start menu, and where the search entry area is located, you can type \\samba.hpc.ufl.edu.
+The network drive server name for /blue and /orange is <code>exasmb.rc.ufl.edu</code>
-At this point a login box will appear for a username and password. Enter these and you should be connected to the system. If you are currently logging into the UF Active Directory (UFAD) domain, you may need to precede your username with "UFHPC\". So, if your username were normally "test", you would instead put "UFHPC\test" for your username.
+The network drive server name for /home is <code>cifs.rc.ufl.edu</code>.
-==Changing Samba Passwords==
+=Mapping Drive Shares=
-To change your samba password (after your samba account has been created), do the following:
+'''Note:''' for automatically mounted filesystem paths like /blue/group or /orange/project use the full path when mounting a samba share to initiate the automounting. e.g. on Windows type the full path into the Windows Explorer Path bar - '\\exasmb.rc.ufl.edu\blue\mygroup\mydir'.
-<pre>
-$ smbpasswd -r samba
-Old SMB password:
-New SMB password:
-Retype new SMB password:
-Password changed for user <USERNAME>
-</pre>
-As can be seen, the command will ask for the old password, then for the new password twice.
-===Administrative Reset===
-In the case that a user has forgotten their samba password, their password can be reset by logging into phpLDAPAdmin and changing the values of '''sambaLMPassword''' and '''sambaNTPassword''' to a known value.

-To allow users to mount HPC filesystems on their workstations on campus (or over campus VPN), we need to add a sambaSAMAccount objectclass to their LDAP entry and set their Sambas password.
