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

smeserver-shared-folders is a new module for SME. It looks 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.


Warning.png Warning:
This contrib is in early stage of development. I use it in limited production now, but there may be some bugs. New features may be added within the next few weeks


Requirements

  • SME Server 7.X

Installation

  • 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 4 parts:

  • 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 exist for the name. You can raise this value with
db configuration set maxShareNameLength 16
  • 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 third part let you configure access to this shared folder using the SMB/CIFS protocol. There's two drop down menu
    • SMB Access lets you configure the type of access: none (no access), enabled and browseable (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 (the directory is created if it doesn't exist)
  • The fourth part let 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 can 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.
    • Force secure connections: if enabled, all the requests will be redirected to use the HTTPS protocol. The redirection is transparent.
    • 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, SSI): this enable the execution of PHP script. If disabled files with a php extension won't be allowed.

Additional options

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

  • 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.
    • 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, and anyway newer MAC OS can access SMB shares so I don't think it's a big problem
  • There's no FTP access. I may add this in a future release.
  • There's no support for CGI scripts if you enable the execution of dynamic content.
  • there's no support for ShadowCopy. I may add this in the future as well.
  • 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

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.

The source for this contrib can be found in the smeserver CVS on sourceforge.
