TeamDrive Hosting Service Administration

Host Servers (Hosts)

Overview

In the overview, you can display the Host Servers, the associated volumes, and some statistical values. The volumes change colour between green, yellow, and red depending on the percentage used.

../_images/HostServerOverview.png

Host Server Admin Console: Server Overview

The values are updated at regular intervals with the “SumUsage” background task. In the process, the associated Depot is updated via the Spaces, as are the volumes and hosts.

Volumes first appear in the view when created as described in the following chapter.

Volumes

Adding more Volumes

By default, the first volume vol01 has already been created during the initial installation.

If you want to extend the storage space or distribute the load across multiple volumes, you can you can add more Space Volumes to a Host Server instance.

Prepare the additional volume, e.g. by creating a block device and file system as outlined in chapter Storage Requirements in the TeamDrive Host Server Installation Guide. Next, create a new mount point in the /spacedata directory, e.g. /spacedata/vol02 and mount the volume.

The ownership of the volume must be assigned to the user that runs the Webserver (usually apache) using the chown command.

Also make sure the file system is properly mounted during system boot (e.g. by adding an entry to the system’s /etc/fstab file).

To add the newly created Volume, log in to the Host Server Administration Console and click Volumes -> Add New Volume in the left navigation bar.

../_images/HostServerNewVolume.png

Host Server Administration Console: Add New Volume

Enter the values as shown in the following example. Make sure to adjust them to match your configuration/environment.

Directory: vol02 (this is the default and should be kept)
Internal Name: sda
State: Operational (active)
Mounted on Host: tdhostsrv001:/spacedata
Max. disk space (in MB): 20,000

The field Directory defines both the Volume Name as well as the name of the mount point in the filesystem below the /spacedata directory.

Note

Volume names must be of the form: volxx, e.g. vol01, vol02.

Please don’t use blanks in volume names.

The name of a volume cannot be changed later because it becomes part of the Space URL which the TeamDrive Clients use to access these spaces.

The field Internal Name is for your reference only, it could contain the name of the volume on your storage system or the local hard disk drive name or partition.

Click Create to create the new volume.

Configuring the Storage Upgrade URL

Storage upgrade: The server informs the TeamDrive Clients how much storage space and traffic is used per Space or account. The Space owner can reserve storage space via the TeamDrive Client and the TeamDrive Clients will generate an URL that opens in the browser. The URL always points to the Hosting Service. This request can be forwarded as required via a rewrite statement.

Open the file /etc/httpd/conf.d/td-hostserver.httpd.conf in an editor and ensure the following configuration option matches your environment.

Please replace in the Rewrite-Rule “bestellung.hostserver.com” with the URL pointing to your own server that provides information about how to upgrade storage. If a user clicks on the “More Storage” button in the TeamDrive Client, the client will open the URL specified.

Using the Rewrite-Rule allows you to redirect these requests to a custom web page where you can offer storage upgrade options:

# This Rewrite is required for the storage-upgrade-buttons
# in the TD-Client (see storage-upgrade-note in the documentation)
RewriteRule ^/upgrade/([a-z][a-z])/order.html(.*) \
https://bestellung.hostserver.com/$1/order.php$2 [R,NE]

The URL called by the client is structured as follows:

http://<domain-name>/upgrade/<2-character-language-code>/order.html

Examples of language codes are: en (English), de (German) and fr (French).

Additionally, the following values are provided by the TeamDrive Client as URL parameters:

  • spaceid: The Space ID of the Space
  • host: The host name (host name and Space ID together are always unique)
  • user: The TeamDrive user name (BASE64-encoded)
  • check: Checksum used to verify whether the request is valid

This allows you to create an order page according to your requirements and adapt it to your own needs (payment link). However, this page must always be present so that the user does not see an error message or an empty page.

Information about Spaces and Accounts can be retrieved from the Hosting Service via the Hosting Service API (an HTTP based interface which uses XML-formatted requests and replies). Please consult the TeamDrive Hosting Service Reference Guide for details.

Functions to delete Spaces and increase Storage limits after payment, for example, are also available. Please contact support@teamdrive.net if you need assistance in using this API.

Disabling the Apache Access Log

In view of the amount of requests issued by the TeamDrive Clients, there is no point in keeping the normal access log activated. We therefore suggest to deactivate it in a production environment. Only the error log should be left enabled. To facilitate this, comment out the following line in the default httpd.conf:

# CustomLog logs/access_log combined

If problems occur in a Space, logging can be activated for a specific Space (see http://httpd.apache.org/docs/2.2/mod/mod_log_config.html). e.g. all access to Space ID 3204 will be logged (the required Apache logging module needs to be enabled again):

SetEnvIf Request_URI 3204 spaceid-3204
CustomLog logs/spaceid-3204-requests.log common env=spaceid-3204

Restart the Apache instance and check the log files for errors.

Changing an Admin User’s Password

The Host Server Administration Console can be accessed by all Admin Users by entering the correct username and password.

An existing user with administrative privileges can change his password directly via the Administration Console’s login page or via the Admin Users page of the Administration Console.

On the login page, click on Change Password... to enable two input fields New Password and Repeat Password that allow you to enter the new password twice (to ensure you did not mistype it by accident). You also need to enter your username in the Username field and the current password in the Password: field above. Click Login and Change Password to apply the new password and log in.

../_images/HostServerChangePassword.png

Host Server Administration Console: Change Password

You can also change your password while being logged into the Administration Console. If your user account has “Superuser” privileges, you can change the password of any admin user, not just your own one.

Click Admin Users to open the user administration page.

The page will list all existing user accounts and their details.

../_images/HostServerAdminUsersList.png

Host Server Administration Console: Admin Users List

Click the username of the account you want to modify. This will bring up the user’s details page.

../_images/HostServerAdminUsersDetails.png

Host Server Administration Console: User Details

To change the password, enter the new password into the input fields New Password and Repeat Password and click Save to commit the change.

The new password will be required the next time this user logs into the Administration Console.

In case you lost or forgot the password for the last user with Superuser privileges (e.g. the default HostAdmin user), you need to reset the password by removing the current hashed password stored in the MySQL Database (Column Password, located in Table pspace.LocalUser). This can be performed using the following SQL query.

Log into the MySQL database using the teamdrive user and the corresponding database password:

[root@hostserver ~]# mysql -u teamdrive -p
Enter password:

[...]

mysql> use pspace;
Database changed

mysql> SELECT * FROM LocalUser WHERE UserName='HostAdmin'\G
*************************** 1. row ***************************
           ID: 1
       Status: 0
     UserName: HostAdmin
        Email: your.name@yourdomain.net
     Password: $2y$10$s0mTNsotNx2Nq4sO13zjDOVnWO6Qx.Lbw1zwcu3efKSXJPB9HGpzO
 ExtReference: NULL
   Privileges: Superuser
 CreationTime: 2015-05-18 10:56:54
LastLoginTime: 2015-05-19 14:21:42
1 row in set (0.00 sec)

mysql> UPDATE LocalUser SET Password='' WHERE UserName='HostAdmin';
Query OK, 1 row affected (0.01 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> quit
Bye

Now you can enter a new password for the HostAdmin user via the login page as outlined above, by clicking the Change Password link, but leaving the Password field empty and only entering the new password twice, followed by clicking the Login and Change Password button.

Enabling Two-Factor Authentication for Superusers

Starting with Host Server version 3.5, the Administration Console supports two-factor authentication via email. In this mode, an Admin User with “Superuser” privileges that wants to log in with his user name and password needs to provide an additional authentication code that will be sent to him via email during the login process. This feature is disabled by default.

The TeamDrive Host Server needs to be configured to send out these authentication email messages via SMTP. The Host Server is only capable of sending out email using plain SMTP via TCP port 25 to a local or remote MTA.

If your remote MTA requires some form of encryption or authentication, you need to set up a local MTA that acts as a relay. See chapter Installing the Postfix MTA in the TeamDrive Host Server Installation Guide for details.

Before you can enable two-factor authentication, you need to set up and verify the Host Server’s email configuration. This can be accomplished via the Host Server’s Administration Console. You need to log in with a user account having “Superuser” privileges in order to conclude this step.

Click Setup / Test Email to open the server’s email configuration page.

../_images/HostServerEmailSetup.png

Host Server Admin Console: Email Setup / Test

Fill out the fields to match your local environment:

SMTP Server:
The host name of the SMTP server accepting outgoing email via plain SMTP. Choose localhost if you have set up a local relay server.
Send Timout:
The timeout (in seconds) that the mail sending code should wait for a delivery confirmation from the remote MTA.
Sender Email Address:
The email address used as the Sender email address during the SMTP delivery, e.g. postmaster@yourdomain.com. This address is also known as the “envelope address” and must be a valid email address that can accept SMTP-related messages (e.g. bounce messages).
Reply-To Email Address:
The email address used as the “From:” header in outgoing email messages. Depending on your requirements, this can simply be a “noreply” address, or an email address for your ticket system, e.g. support@yourdomain.com.
Email Sending Host:
The host name used in the HELO SMTP command, usually your Host Server’s fully qualified domain name.
Email Address:
The primary administrator’s email address. This address is the default recipient for all emails that don’t have an explicit receiving address. During the email setup process, a confirmation email will be sent to this address.

After you’ve entered the appropriate values, click Send Test Email to verify the email setup. If there is any communication error with the configured MTA, an error message will be printed. Check your configuration and the MTA’s log files (e.g. /var/log/maillog of the local Postfix instance) for hints.

If the configuration is correct and functional, a confirmation email will be delivered to the email address you provided. It contains an URL that you need to click in order to commit your configuration changes. After clicking the URL, you will see a web page that confirms your changes.

This concludes the basic email configuration of the Host Server. Now you can enable the two-factor authentication by clicking Settings -> UseTwoFactorAuth. Change the setting’s value from False to True and click Save to apply the modification.

../_images/HostServerTwoFactorAuthConfig.png

Host Server Admin Console: Use Two Factor Authentication

Now two-factor authentication for the Administration Console has been enabled.

The next time you log in as a user with “Superuser” privileges, entering the username and password will ask you to enter a random secret code, which will be sent to you via email to the email address associated with your administrator account. Enter the code provdided into the input field Authentication Code to conclude the login process.

Changing the MySQL Database Connection Information

The Host Server Apache modules mod_pspace and mod_yvva as well as the yvvad daemon that performs the td-hostserver background tasks need to be able to communicate with the MySQL management database of the Host Server.

If you want to change the password of the teamdrive user or move the MySQL database to a different host, the following changes need to be performed.

To change the MySQL login credentials, edit the file /etc/td-hostserver.my.cnf. The password for the teamdrive MySQL user in the [p1db] option group must match the one you defined earlier:

[p1db]
database=pspace
user=teamdrive
password=<password>
host=127.0.0.1

If the MySQL database is located on a different host, make sure to modify the host variable as well, providing the host name or IP address of the host that provides the MySQL service. If required, the TCP port can be changed from the default port (3306) to any other value by adding a port=<port> option.

Manually creating a Depot

The default Depot is always linked to a single user. Using the Host Server Admin Console, it is possible to create Depots that are not linked to a particular user. Each TeamDrive Client that has a Depot file can create Spaces within it. A Depot must always be assigned to a TeamDrive user when it is created via the Web Interface . This is the Depot owner, and only they can later expand the storage space from their TeamDrive Client by using the upgrade button.

The Depot files are encrypted using an external tool the tshs binary. The name and path of the executable is stored in the setting TSHSExecutable. This should be configured correctly during the TeamDrive software installation process, and need not be altered.

To set up a new Depot, click Space Depots -> Add New Depot in the navigation bar.

../_images/HostServerNewDepot.png

Host Server Admin Console: Add New Depot

Fill out the fields based on the requirements for this Depot.

Owner:
Click Edit to select a user from the selection list to which the Depot will be assigned. Use the Selection Filter input field to search for a specific username after clicking the Apply button. Click the desired username and click OK to finish the selection.
../_images/HostServerNewDepotOwner.png

Host Server Admin Console: New Depot Owner Selection

Space Depot Name:
Any name can be selected for the Space Depot name. The name appears in the TeamDrive Client in the list of available Depots.
Contract:
An account number used as a reference for other systems.
Max. Disk Space and Traffic Limit:
These values should be set up at a ratio of at least 1:10 because users invite each other to the Spaces and the traffic thus may always be higher than the storage space used.

Click Create to create the Depot.

By clicking the Depot Access File link in the Depot Details screen, you can download the respective Depot file, which can be imported into the TeamDrive Client.

Increasing Volume Storage Space

The first scaling strategy is to add additional volumes to increase the available storage capacity. You should consider adding more volumes (or increase the size of a volume), if any existing volume reaches 60% of utilization.

For additional scaling, we recommend to add an object store which will scale unlimited. We offer additional tools for moving local data to the object store. An extended apache module will redirect client requests to the data that was moved to the object store. The clients could read the data directly from the object store, if it supports the HTTP protocol.

Please contact sales@teamdrive.com for supported object stores.

Optional Configuration Settings

In the settings you can set up configurations, such as the IP address of the external server needed for the XML invocations referred to into access the account on the Hosting Service and automatically upgrade the storage space, if needed (after payment is received). Only requests from this IP are then accepted. The value in “UpgradeServerIP” is delivered empty so that no safety check is done.

Using HTTPS for publishing files

TeamDrive can publish files so that they can be accessed without using a TeamDrive Client. The default protocol for uploading and downloading the data is HTTPS. This requires Apache to be appropriately configured and a valid SSL certificate must be installed. If security of published files in not an issue you can set the system parameter HttpsUsedByPublish to False.

Enabling storing Space Names

Each created Space will be stored on the Hosting Service. This record has different information such as: user, account, status and usage information and also the original Space title. For security reasons, the storing the Space names on the server is disabled by default . To enable storing the Space names: look for a boolean setting named StoreSpaceNames and set the value to true.

API return Space Names

By default, Space names will not be returned in the API for security reasons. To enable returning Space names: add a boolean setting with the name API_ReturnSpaceNames and set the value to true (this setting will have no effect, if you disable StoreSpaceNames as described above).

Using HTTPS for the Admin Console

HTTPS is used by default to access the web-based Host Server Admin Console. For this reason the Apache HTTP Server must be configured to support SSL and a valid certificate installed. If the Admin Console is only accessed behind the firewall, then you can allow HTTP access by setting the system setting HttpsUsedByAdmin to False.

Reporting Usage Statistics

It’s possible to generate a monthly report that contains detailed statistics about all existing Depots and Spaces within these depots, including the monthly traffic and disk usage. The report is prepared in the form of an XML file statistic_from_MM_DD_YYYY_to_MM_DD_YYYY.xml by p1_autotask at the beginning of each month. To enable the generation of these statistics, you need to change the Host Server setting SpaceStatisticEnabled from False to True. By default, the resulting report files will be written to /tmp/. If you prefer a different location, you can provide an alternative directory name in the configuration setting SpaceStatisticExportPath.

External Traffic

The Hosting Service can store data externally (e.g., Amazon S3 storage). Custom modules are needed for the connection, which you can request from sales@teamdrive.net. Outsourcing and directly accessing the client on external storage also generates external traffic. This is recorded separately and added to the direct traffic for the Depot. For transparency, this is displayed separately in the Web Interface . However, the value is only visible if the required module is used. The summarized value of the external traffic and the traffic directly to the host is provided to the TeamDrive Client.
