Notes about the Invision Power File Manager (IPFM)

The IPFM software does not work on the LyX server as it's not compatible with the (later) PHP version used on the server. /chr

You can not access the Invision Power File Manager (IPFM) through the following URI:

In order to upload files, you will need to login as the user lyx and give a password. The current password is simply obtained by asking for it on one of the LyX mailing lists.

If you only wish to browse the existing files, you can login as the user guest, which doesn't require a password.

2006-01-30: I just discovered that IPFM has been discontinued :-( Here is what "remains" http://www.rebelinblue.com/?fm For safety, I placed a copy of the archive in uploads:/Site/IPFM (And in irony, you need to use the file manager to access that directory since listings are disallowed on this server) /chr

Installation

The Invision Power File Manager (IPFM) was installed as follows.

  1. Copy files etc to pmwiki/ipfm/ and fixing permissions, see below
  2. Executing pmwiki/ipfm/install.php (and then deleting it).
    A copy of the chosen administrator password is stored in the file pmwiki/passwords.txt on the wiki server in case we forget it...
  3. Removing pmwiki/ipfm/install.php for security reasons
  4. Added the user lyx, the password will be published on the lists. See IPFM administration below and also the lyx user below
Note: In order to get proper permissions of created files and directories, use the admin tool to set
          Settings/Script settings/Default CHMOD
to 775 (this enables members of the group wiki to manually manipulate files and directories via shell access).
In addition, the umask had to be set by patching index.php by adding umask(002);. The statement was added on line 53 of index.php.

IPFM administration

The administration tool is started from this URI:

The password is stored in pmwiki/passwords.txt on the wiki server, just in case we forget it...

Permissions and ownership

Special effort was taken to fix ownership of directories so that everything belongs to the group wiki (wiki administrators are members of this group). In addition, the group-'s' bit has been set on directories, so that newly created files etc will also belong to the wiki group.

Here is the directory structure:

 
Perm.	User	: Group	Directory
2775	chr 	: wiki  ipfm
2775    chr	: wiki  ipfm/admin
2775    apache	: wiki  ipfm/images
2775    apache	: wiki  ipfm/images/icons
2775    apache	: wiki  ipfm/languages
2775    chr	: wiki  ipfm/modules
2775    apache	: wiki  ipfm/settings
2775    apache	: wiki  ipfm/settings/templates
2775    apache	: wiki  ipfm/settings/templates/javascript
2775    apache	: wiki  ipfm/templates

The above was created by using the 's' bit on pmwiki/ipfm/, and having apache execute a .php-script which copied parts of the archive containing IPFM. This ensured the files and directories are ownded by apahce, enabling the web server user to write to these files in the future, without having everybody being able to write to the files.

Then one of the administrators (here it was chr) manually overwrote some of the directories, so that they aren't owned by apache.
