How to Mount an SMB Share on a Directory You Own

Language:

Note - If you own the directory on which you want to mount a share, you can perform the mount operation yourself. If you do not own the directory, you must perform the mount operation as the owner of the directory or as superuser.

Verify that the network/smb/client service is enabled.
```
$ svcs network/smb/client
STATE          STIME    FMRI
online         19:24:36 svc:/network/smb/client:default
```
This service is enabled by default, so the usual state for the service is online. To enable the service, type the following command:
```
$ svcadm enable -r network/smb/client
```
Find the share that you want to mount from a server.
```
$ smbadm show-shares [-A | -u username] [-t] server
```
–A

Enables you to view shares anonymously

–u

Indicates the user to authenticate on the specified SMB server

–t

Displays a heading for the output

If neither the –A nor the –u option is specified, the user that is running the command is authenticated on the SMB server.
Create a mount point on which to mount the share.
```
$ mkdir mount-point
```
For example, to create a mount point called /tmp/mnt, type:
```
$ mkdir /tmp/mnt
```

Perform the mount on your directory.

$ mount -F smbfs [-o dirperms=octal-triplet,fileperms=octal-triplet,gid=group-ID,\
uid=user-ID,user=username,...] //server/share mount-point

For example, to mount the tmp share from the solarsystem server on the /tmp/mnt mount point, type:

$ mount -F smbfs //solarsystem/tmp /tmp/mnt

You can use the following options to set the directory access permissions in the client:

dirperms=octal-triplet – Specifies the directory permissions that you can set to the directories. The dirperms permission does not affect the access policies that the SMB server maintains. By default, the system uses the value that you set for the fileperms. The system then adds an execute permission to the fileperms settings.

For example, you can set dirperms to 700 to prevent group members from accessing the directory.

# ls -ld /export/home/user1/mnt
drwxr-xr-x 2 user1 staff 2 Dec 16 13:57 /export/home/user1/mnt  
# mount - F smbfs -o dirperms=770 //server/share /export/home/user1/mnt

# su - user2  
user2% gid -gn  
staff
user2% ls -ld /export/home/user1/mnt/test  
drwxrwx---+ 1 user1 staff 512 Aug 27 14:58 /export/home/user1/mnt/test  
user2% exit  

# umount /export/home/user1/mnt
# mount - F smbfs -o dirperms=700 //server/share /export/home/user1/mnt  

# su -user2  
user2% ls -ld /export/home/user1/mnt/test  
/export/home/user1/mnt/test:Permission denied

fileperms=octal-triplet – Specifies the file permissions that you can set to the files on a mount point. The fileperms permission does not affect the access policies that the SMB server maintains. By default, the file permission is 700.

For example, you can set fileperms to 770 to enable the group associated with the mount point to access files on the mount point.

# ls -ld /export/home/user1/mnt
drwxr-xr-x 2 user1 staff 2 Dec 16 13:57 /export/home/user1/mnt  
# mount - F smbfs //server/share /export/home/user1/mnt  

# su - user2  
user2% gid -gn  
staff  
user2% ls -l /export/home/user1/mnt/test.file
/export/home/user1/mnt/test.file: Permission denied  
user2% exit  

# umount /export/home/user1/mnt  
# mount - F smbfs -o fileperms=770 //server/share /export/home/user1/mnt  

# su - user2  
user2% ls -l /export/home/user1/mnt/test.file
-rwx------+ 1 user1 staff 0 Dec 16 15:56 /tmp/mnt/test.file

gid=group-ID – Specifies the group ID that you can set as the effective group. The effective group uses the group permissions that is set for the mount point. By default, the value of gid is the group ID of the mount point.

The following example shows that the group ownership of the mount point /export/home/user1/mnt is set to staff. You can set the gid to not_staff to enable the users in the not_staff group to access the files on the mount point.

# ls -ld /export/home/user1/mnt  
drwxr-xr-x 2 user1 staff 2 Dec 16 13:57 /export/home/user1/mnt  
# mount -F smbfs -o dirperms=770 //server/share /export/home/user1/mnt  

# su -user2  
user2% gid -gn 
not_staff
user2% ls -ld /export/home/user1/mnt/test 
/export/home/user1/mnt/test: Permission denied  
user2% exit  

# umount /export/home/user1/mnt  
# mount -F smbfs -o gid=not_staff,dirperms=770 //server/share /export/home/user1/mnt

# su - user2  
user2% ls -ld /export/home/user1/mnt/test
drwxr-x---+ 1 user1 staff 512 Dec 16 15:56 /tmp/mnt/test

uid=user-ID – Specifies the local user ID that you can set as the effective owner. The effective owner uses the owner permissions that is set for the mount point. By default, the value of uid is the user ID of the mount point.

For example, to enable user2 to access the mounted files, you can set uid to user2.

# ls -ld /export/home/user1/mnt  
drwx------ 2 user1 staff 2 Dec 16 13:57 /export/home/user1/mnt  
# mount - F smbfs //server/share /export/home/user1/mnt  

# su - user2  
user2% ls -ld /export/home/user1/mnt/test
/export/home/user1/mnt/test: Permission denied  
user2% exit  

# umount /export/home/user1/mnt  
# mount - F smbfs -o uid=user2 //server/share /export/home/user1/mnt  

# su - user2  
user2% ls -ld /export/home/user1/mnt/test
drwxr-x---+ 1 user1 staff 512 Dec 16 15:56 /tmp/mnt/test
