Capabilities

The Yamaha MODX Music Synthesizer has a builtin class compliant audio interface which works out of the box under Linux. The audio capabilities are:

• Sampling rate: 44100hz (fixed)
• Analog outputs: 10
• Analog inputs: 4
• MIDI inputs/outputs: 3

Jack settings

Only with the Jack audio system all 10 outputs and 4 inputs can be used with the following settings:

• Sampling rate: 44100 (fixed)
• Frames: 512 / 256 / 128 / 64 / 32 / 16 (the lower the better for latency)
• Buffer: 3 / 2 (the lower the better for latency)

MIDI

The MODX comes with four MIDI templates for proprietary DAWs, there are three MIDI inputs/outputs:

• 1: Contains notes, controllers and time syncing
• 2: Should be used as a control port to connect a DAW (to a Mackie Control Unit)
• 3: Reserved for future use?

DAW Integration

DAW integration has moved here.

Email for small setups with Postfix

A lot of system services rely on email or integrate this service. To use the Univention infrastructure with single email addresses, the following postfix configuration can be used.These instructions describe a setup for three freemail accounts using two different providers. Do not enter the freemail domains in UCS as a mail domain.

First install the following apps using the app center:

• Fetchmail
• Kopano Core (or another groupware)
• Kopano Webapp
• Kopano Z-Push

Receiving emails

Add the three user accounts using the UMC, enter the freemail address as the primary e-mail account. Configure fetchmail by opening the extended configuration from all the three user accounts. Send an e-mail from external clients to these accounts and wait up to 20 minutes until the e-mails appear in Kopano.

Sending emails

Add the following lines to /etc/postfix/main.cf.local (not main.cf):

sender_dependent_relayhost_maps = hash:/etc/postfix/relaymap
smtp_sender_dependent_authentication = yes
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwords
smtp_sasl_security_options = noanonymous
transport_maps = hash:/etc/postfix/transport

Activate changes:

ucr commit /etc/postfix/main.cf

Define freemailer smtp relays, create the file /etc/postfix/relaymap

@freemail1.de smtp.freemail1.de
@freemail2.de smtp.freemail2.de

Create hashfile:

postmap /etc/postfix/relaymap

Now configure the passwords for sending e-mails for every account, create the file /etc/postfix/sasl_passwords

user1@freemail1.de user1@freemail1.de:User1MailPassword
user2@freemail1.de user2@freemail1.de:User2MailPassword
user3@freemail2.de user3@freemail2.de:User3MailPassword

Create hashfile and restart postfix:

postmap /etc/postfix/sasl_passwords
service postfix restart

Local delivery

At this point Kopano webmail can be used to send e-mails from one account to another, but every mail is sent to and fetched from the freemail provider. To ensure that local accounts communicate only using the UCS add the following:

Add to /etc/univention/templates/files/etc/postfix/transport.d/10_base

user1@freemail1.de lmtp:127.0.0.1:2003
user2@freemail1.de lmtp:127.0.0.1:2003
user3@freemail2.de lmtp:127.0.0.1:2003

Activate changes with:

ucr commit /etc/postfix/transport
service postfix restart

UCS as a Server infrastructure

The Univention Corporate Server (UCS) based on Linux allows the central administration of users, systems and services for small, medium and huge infrastructures. The Core Edition can be used for free, a lot of popular and complex software solutions like groupware or office services can be installed easily using a web frontend.

User and access management

every user account is managed through a web interface, Univention realised the management of 30 million users for one customer.

Functions

The Univention infrastructure provides a lot of network services, hardware integration and administration frontends.

Recommendations

• Installing Univention in a virtual machine allows creating backups/snapshots of the whole system easily.
• Many services integrate or rely on email as a service. Configuring email following the documentation is a good starting point. To use single email addresses without a registered domain, follow these instructions.

S.u.S.E. 4.4.1 can still be installed using a virtual machine (KVM/QEMU). Thanks to very old standard technologies like ‘PS/2’ and ‘VGA’ even the graphical desktop can be configured. The installation was quite complicated, but there was a manual containing over 500 pages of help. Installation requirements were 8MB of RAM for text based operations and 12MB for the X-Window system.

The CDROM was not bootable, you had to use a floppy boot disk.YAST was used for installation and configuration:

Linux already supported a lot of hardware:

The graphical desktop had to be started using the command line with ‘startx’.

Conclusions

The graphical interface has not changed that much. Vim and the Midnight Commander (mc) were already preinstalled.

Linux runs well on an old Laptop after installing a SSD. A quick test with Linux Mint Xfce 20.1 showed:

• Boot (Grub) to login: 15 seconds
• Login to desktop: 8 seconds

The left four of the five buttons on top of the keyboard beneath the power button do not work out of the box:

To enable these buttons permanently, enter:

sudo crontab -e

Append the line:

@reboot /usr/bin/setkeycodes e001 182 e002 183 e003 184 e004 185

Now these buttons can be used for starting programs or other shortcuts.

Thunderbird can be used for e-mails, appointments, notes, RSS-Feeds and much more.

E-Mail

Thunderbird recognizes the correct settings from many email providers. Just enter your email address and the correct password. The use of the IMAP protocol ensures that the emails stay on the providers servers. Benefits: emails can be sent using a file manager or an office suite, there is a full integration into the desktop

Calendar

Lightning is an integrated component which handles calendars using the CalDAV protocol.

Address book / ActiveSync

Thunderbird itself has no CardDav support at the moment. You can install the TBSync plugin for CalDAV, CardDAV and
Exchange ActiveSync (EAS) support. Be sure to install the TBSync provider for the above protocols, too.

Debugging / Logging

Open a terminal and enter:

export NSPR_LOG_MODULES=all:5
thunderbird

This will enable the maximum debug output for all modules. Further informations for logging can be found on Mozillas Web Docs
