h1. DUL 20 Configuration

The DUL can be configured via

* OSS-RC (Ericsson operations support system-radio and core - a centralized server)

* EMA (Element Manager - a Windows WebUI utility)

* moshell (a javabased command line utility - runs on linux)

* ncli (a command line utility which runs on the DUL itself)

h2. Configuration tools

h3. EMA - Element Manager

There are different versions of this tool. An ancient version can be downloaded from the DUL itself:

http://169.254.1.10/em/index.html

h3. ncli

With the ncli basic operations can be performed. However the ncli usually doesn't have a ManagedObject tree loaded which means it doesn't know which attributes an ManagedObject can have.

h3. moshell

The most powerful tool to configure the DUL. It loads the ManagedObject on startup. But can also operate offline on backups.

See [[moshell]] for further information how to install and use it.

h2. Backup & Recover

A backup of the DUL can be created via ftp and serial.

The serial is required to boot into the recovery mode.

h3. Boot DUL into recovery

Configure the serial connection to **9600** baud (alternative **115200**).

Restart the DUL by removing the power for 5 seconds.

If the connection is working a boot message is shown:

The DUL should be reachable by icmp/ping and ftp.

h3. Recover

Backup the "partitions" /c and /d from the DUL to be safe.

/c and /d contains configuration and system files, application and firmwares.

The DUL supports a ftp service.

Mount the volume of c2 on the DUL first.

<pre>

$ mount_c2

Use your local ftp terminal to get all data. Either graphical client or text.

As an example **gftp** (text version) is used in a terminal on the laptop.

<pre>

linux ~> mkdir backup ; cd backup

linux ~> gftp rbs:rbs@169.254.1.10
