−
* The second part is to define permission access. For each group of users, you can grant read only or read/write access. If none is checked, the shared folder won't be accessible (unless for the admin user which has always access to every shared folders)
+
* The second part lets you configure access to this shared folder using the SMB/CIFS protocol. There's three drop down menus
 +
**'''SMB Access''' lets you configure the type of access: '''none''' (no access), '''enabled and browse-able''' (enabled, and visible if you browse available shares of the server) or '''enabled, hidden''' (enabled, but you need to know the exact name to access it)
 +
**'''Recycle bin''' lets you configure a network recycle bin option available in samba. Available options are '''none''' (recycle bin is disabled), '''enabled, keep only the latest version''' (enable the recycle bin, but only keep the latest version if two file with the same name are deleted), or '''enabled, keep a copy of all versions''' (enable the recycle bin and keep a copy of every file deleted). When the recycle bin is enabled, if a user delete a file, instead of removing it from the server, samba will move it the the '''Recycle Bin''' directory at the top of the shared folder.
 +
**'''Recycle Bin Retention''': lets you define the retention time of file in the recycle bin. After this period of time, files are deleted.
 +
 
 +
* The third part lets you configure access to this shared folder using the HTTP/HTTPS protocol. There're also several options:
 +
**'''Web Access''': works like ibays. The only difference is that when a password is required, users have to use their own login/password instead of a global one. Users need at least read access to this share or they won't be allowed. This setting is only for web access, not FTP.
 +
**'''WebDav Support''': Enable webdav on this share. Only effective if Web Access is enabled. Write access with WedDav will always require to login.
 +
**'''Force secure connections''': if enabled, all the requests will be redirected to use the HTTPS protocol. The redirection is transparent. This is highly recommended if a password is required.
 +
**'''Indexes''': Let you control if the server should generate an index of all the files if no index.html file is found. You can disable it if you don't want everyone to have access to the list of files. This setting is global for the shared folder, I mean, if enabled, any directory which doesn't have a index.html file will be indexed.
 +
**'''Dynamic content execution (PHP, CGI, SSI)''': this enable the execution of PHP script. If disabled files with php, php3, phtml, cgi or pl as extension won't be allowed. If enabled, you can create a directory named "cgi-bin" in your shared folder. It will allow execution of cgi scripts
 +

When the recycle bin is enabled, if a user delete a file, instead of removing it from the server, samba will move it the the '''Recycle Bin''' directory at the top of the shared folder (the directory is created if it doesn't exist)

* You cannot work with files bigger than 2GB, this is a limitation of PHP on 32 Bits system
−
**'''Force secure connections''': if enabled, all the requests will be redirected to use the HTTPS protocol. The redirection is transparent.
+
* Files uploaded with Pydio will not be counted for quota limitations (same applies for WebDav uploads). This is because the file will belong to www user, and not the real user.
−
**'''Indexes''': Let you control if the server should generate an index of all the files if no index.html file is found. You can disable it if you don't want everyone to have access to the list of files. This setting is global for the shared folder, I mean, if enabled, any directory which doesn't have a index.html file will be indexed.

=== Encryption ===
 +
 
 +
Since smeserver-shared-folders-0.1-50, you can now encrypt all the data stored in a shared folder. For this to work, you first have to install fuse-encfs from the [[Epel|EPEL]] repository
 +
 
 +
{{:epel|transcludesection=epel8}}
 +
 
 +
After adding it to the database updating the configuration file is required by issuing:
 +
 
 +
signal-event yum-modify
 +
 
 +
To install fuse-encfs on sme8
 +
yum --enablerepo=epel install fuse-encfs
 +
 
 +
 
 +
To install fuse-encfs on sme9
 +
yum --enablerepo=smecontribs --enablerepo=epel install fuse-encfs
 +
 
 +
After installing fuse-encfs, make sure the fuse module is loaded
 +
lsmod | grep fuse
 +
 
 +
Now, when you create a new shared folder, you have a new option to encrypt the data. You'll have to type a password, and to select '''enabled''' for the encryption.<br /><br />
 +
 
 +
 
 +
'''An encrypted shared folders can be "protected" or "enabled" and contains for each state a different corresponding data''' ( = a shared folder get a data for "enable" and another for "protected"):
 +
* When the share is "protected", you can write to it: files written to the server while the share is protected will not be encrypted, instead, it'll be directly stored into the files folder in the share.
 +
* When the share is "enabled", you mount the .store folder over the files folder, using encfs. When this happens, the cleartext dataset (stored directly in files) will be hidden, and you have access to a second, completely separated data set. The data you write when the share is enabled will be encrypted on the fly, and stored in the .store folder.
 +
:As soon as you "protect" the share (or when the inactivity timeout occurres), the encrypted volume is unmounted, and you get the unencrypted share available again
 +
 
 +
Changing the state of an encrypted shared folder can be done through the 'Shared Folder Encryption' panel in the server-manager.
 +
You can grant access to this panel to all users using the [[UserManager]] contrib. Users will only be able to toggle mode of shared folders they have access to (and of course, they need to know the correct password).
 +
 
 +
'''''Note:''''' If already mounted, Samba looses the access to the shared folder if its status "protected"/"enabled" is modified. Then the share must be umounted and mounted again to get access to the other data set.
 +
 
 +
 
 +
==== Limitations with encryption ====
 +
Before using encryption on a shared folder, you should be aware of some limitations:
 +
* Encryption is done on the fly in user-space using encfs, accessing data may be a bit slower when encryption is enabled
 +
* Encryption can only be enabled at creation time, it's not possible to encrypt an existing shared folders
 +
* Read Only permission is '''not''' supported on encrypted shared folders, only full read/write access is possible (this is a limitation of fuse which doesn't pass ACL permissions). If you set read only access to some groups, it'll just be ignored
 +
* The current implementation doesn't provide any option to change the password from the web GUI. If you want to change the password, you can do so from the command line with the encfsctl utility
 +
* There's '''NO WAY''' to recover the data if you forget the password.

=== Backup and Restore ===
 +
The standard backup process should backup all your shared folders. If you have to restore the data to another server, you'll have to re-install the contrib. Once everything is restored, you'll have to run '''signal-event share-modify-files''' for each share, because permissions on shared folders uses extended ACL which are not backed up with most tools. This is not a big problem because ACL are also stored in the accounts DB. The signal-event will just re-apply the configured ACL on the files:

for SHARE in $(db accounts printtype | grep share | cut -d'=' -f1); do

    signal-event share-modify-files $SHARE

Version

Contrib 10:
Contrib 9:
smeserver-shared-folders
The latest version of smeserver-shared-folders is available in the SME repository, click on the version number(s) for more information.


Description

Shared folders are more or less like ibays (I took a lot of code from the ibay module), but with more flexibility on file permissions as it supports ACL. There're also some additional options in the panel.

Requirements

  • Min SME Server 7.X

Installation 8.x and 9.x

  • install the rpms
yum --enablerepo=smecontribs install smeserver-shared-folders
  • Mount your file system(s) with the ACL option

If you use a standard SME server installation: 

signal-event post-upgrade; signal-event reboot

should do the trick. If you don't like to reboot your server every time you install something (just like me :)), you can just run: 

expand-template /etc/fstab

Check your file system mounted in /home/e-smith/files/ has the acl option, for example: 

# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/                 /                       ext3    usrquota,grpquota,acl        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /dev/shm                tmpfs   defaults        0 0
none                    /proc                   proc    defaults        0 0
none                    /sys                    sysfs   defaults        0 0
LABEL=SWAP-rd/c0d0p3    swap                    swap    defaults        0 0

You may have to manually add the acl option in /etc/fstab if you have mounted another file system here. Once the option is in fstab, you can just remount the partitions, for example: 

mount -o remount /

or 

mount -o remount /home/e-smith/files

Check everything is ok: 

[root@sme ~]# mount
/dev/sda2 on / type ext3 (rw,usrquota,grpquota,acl)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/rd/c0d0p1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

Storage

All the shares you create will be stored in /home/e-smith/files/shares/<sharename>/files The latest /files directory is to keep the same structure than ibays. There's no html and cgi-bin directories. You'll never see the "files" directory as the root (for SMB and HTTP) will always be /home/e-smith/files/shares/<sharename>/files.

Features

A lot of options are available in the panel. When you create a new shared folder, or modify an existing one, the page is divided in up to 5 parts (depending on other packages you might have installed like encfs and Pydio):

  • The first part let you enter a name and a comment for this shared folder. This part works exactly the same way than ibay. An initial limit of 12 characters exists for the name. You can raise this value with
db configuration set maxShareNameLength 16
  • The second part lets you configure access to this shared folder using the SMB/CIFS protocol. There's three drop down menus
    • SMB Access lets you configure the type of access: none (no access), enabled and browse-able (enabled, and visible if you browse available shares of the server) or enabled, hidden (enabled, but you need to know the exact name to access it)
    • Recycle bin lets you configure a network recycle bin option available in samba. Available options are none (recycle bin is disabled), enabled, keep only the latest version (enable the recycle bin, but only keep the latest version if two file with the same name are deleted), or enabled, keep a copy of all versions (enable the recycle bin and keep a copy of every file deleted). When the recycle bin is enabled, if a user delete a file, instead of removing it from the server, samba will move it the the Recycle Bin directory at the top of the shared folder.
    • Recycle Bin Retention: lets you define the retention time of file in the recycle bin. After this period of time, files are deleted.
  • The third part lets you configure access to this shared folder using the HTTP/HTTPS protocol. There're also several options:
    • Web Access: works like ibays. The only difference is that when a password is required, users have to use their own login/password instead of a global one. Users need at least read access to this share or they won't be allowed. This setting is only for web access, not FTP.
    • WebDav Support: Enable webdav on this share. Only effective if Web Access is enabled. Write access with WedDav will always require to login.
    • Force secure connections: if enabled, all the requests will be redirected to use the HTTPS protocol. The redirection is transparent. This is highly recommended if a password is required.
    • Indexes: Let you control if the server should generate an index of all the files if no index.html file is found. You can disable it if you don't want everyone to have access to the list of files. This setting is global for the shared folder, I mean, if enabled, any directory which doesn't have a index.html file will be indexed.
    • Dynamic content execution (PHP, CGI, SSI): this enable the execution of PHP script. If disabled files with php, php3, phtml, cgi or pl as extension won't be allowed. If enabled, you can create a directory named "cgi-bin" in your shared folder. It will allow execution of cgi scripts


Warning.png Warning:
IP addresses and networks which are allowed to access the server-manager (in Security -> Remote Access -> Remote Management) will be considered local for web access. This means those IP and networks will have access to shared folders which are restricted to local networks


Pydio

If you install the Pydio contrib, you'll have a new option displayed in the configuration of the shared folders. With this, you can easily enable the access of any shared folders through Pydio.

Limitations of Pydio

  • You cannot work with files bigger than 2GB, this is a limitation of PHP on 32 Bits system
  • Files uploaded with Pydio will not be counted for quota limitations (same applies for WebDav uploads). This is because the file will belong to www user, and not the real user.

Encryption

Since smeserver-shared-folders-0.1-50, you can now encrypt all the data stored in a shared folder. For this to work, you first have to install fuse-encfs from the EPEL repository 


yum install smeserver-extrarepositories-epel -y


After adding it to the database updating the configuration file is required by issuing: 

signal-event yum-modify

To install fuse-encfs on sme8 

yum --enablerepo=epel install fuse-encfs


To install fuse-encfs on sme9 

yum --enablerepo=smecontribs --enablerepo=epel install fuse-encfs

After installing fuse-encfs, make sure the fuse module is loaded 

lsmod | grep fuse

Now, when you create a new shared folder, you have a new option to encrypt the data. You'll have to type a password, and to select enabled for the encryption.


An encrypted shared folders can be "protected" or "enabled" and contains for each state a different corresponding data ( = a shared folder get a data for "enable" and another for "protected"):

  • When the share is "protected", you can write to it: files written to the server while the share is protected will not be encrypted, instead, it'll be directly stored into the files folder in the share.
  • When the share is "enabled", you mount the .store folder over the files folder, using encfs. When this happens, the cleartext dataset (stored directly in files) will be hidden, and you have access to a second, completely separated data set. The data you write when the share is enabled will be encrypted on the fly, and stored in the .store folder.
As soon as you "protect" the share (or when the inactivity timeout occurres), the encrypted volume is unmounted, and you get the unencrypted share available again

Changing the state of an encrypted shared folder can be done through the 'Shared Folder Encryption' panel in the server-manager. You can grant access to this panel to all users using the UserManager contrib. Users will only be able to toggle mode of shared folders they have access to (and of course, they need to know the correct password).

Note: If already mounted, Samba looses the access to the shared folder if its status "protected"/"enabled" is modified. Then the share must be umounted and mounted again to get access to the other data set.


Limitations with encryption

Before using encryption on a shared folder, you should be aware of some limitations:

  • Encryption is done on the fly in user-space using encfs, accessing data may be a bit slower when encryption is enabled
  • Encryption can only be enabled at creation time, it's not possible to encrypt an existing shared folders
  • Read Only permission is not supported on encrypted shared folders, only full read/write access is possible (this is a limitation of fuse which doesn't pass ACL permissions). If you set read only access to some groups, it'll just be ignored
  • The current implementation doesn't provide any option to change the password from the web GUI. If you want to change the password, you can do so from the command line with the encfsctl utility
  • There's NO WAY to recover the data if you forget the password.

Additional options

Some advanced settings are not available on the panel, but only with db commands:

Database Key Key type
accounts [name of share] share


  • Various options
Option Value Default Description
ManualPermissions enabled / disabled disabled if you set this key to enabled, the permissions will only affect web access (HTTP, WebDav, Pydio), and will not touch the permissions on the file system. This can be used to host web applications with custom permissions.
Hide yes / no no If set to yes, this share will not be listed in the server-manager
Removable yes / no yes If set to no, you won't be able to remove this share through the server-manager
Audit enabled / disabled enabled Enable or disable activity logging in /var/log/messages
  • Options for Web access:
    • AllowOverride: You can configure the AllowOverride directive of apache if web access is enabled. See this page for a list of available option
    • FollowSymLinks: (enabled|disabled). Should apache follows symlinks ?
    • PHPRegisterGlobals: (enabled|disabled). Enable PHP register global for this share.
    • PHPAllowUrlFopen: (enabled|disabled). Enable PHP allow_url_fopen for this share.
    • PHPMemoryLimit: Set a memory limit for PHP. This limit only apply to this share
    • PHPMaxExecutionTime: Set a time execution limit for PHP. This limit only apply to this share
  • Options for SMB access:
    • cscPolicy: (disabled|manual|documents|programs). Control client-side caching. Don't touch this if you don't know what it means. It can have unexpected behaviour.
    • OpLocks: (enabled|disabled). Control the oplocks option of samba (default is enabled)
    • VetoOplockFiles: Control the veto oplock files of samba


Example: 

db accounts setprop myshare AllowOverride All PHPMemoryLimit 50M PHPMaxExecutionTime 600
signal-event share-modify myshare

Missing features

Even if this contrib brings some new options compared to ibays, some others are missing:

  • There's no access using the atalk protocol. I don't have any MAC OS here to test the feature, and anyway newer MAC OS can access SMB shares so I don't think it's a big problem
  • there's no support for ShadowCopy. I may add this in the future
  • You cannot choose a shared folder as the content of a virtual domain. This is because it'd require a modification of a core package

Backup and Restore

The standard backup process should backup all your shared folders. If you have to restore the data to another server, you'll have to re-install the contrib. Once everything is restored, you'll have to run signal-event share-modify-files for each share, because permissions on shared folders uses extended ACL which are not backed up with most tools. This is not a big problem because ACL are also stored in the accounts DB. The signal-event will just re-apply the configured ACL on the files: 

for SHARE in $(db accounts printtype | grep share | cut -d'=' -f1); do
    signal-event share-modify-files $SHARE
done

Uninstall

If you want to remove the contrib, just run: 

yum remove smeserver-shared-folders

You need to manually removes files in /home/e-smith/files/shares if you want to remove every shares created. You may also want to edit /etc/fstab to remove the acl option.
