UC-8410A Series Linux Software Getting Started

2-2

Software Architecture

The Linux operating system that is pre-installed on the UC-8410A-LX series computers follows standard Linux

architecture, making it easy to run any program that follows the POSIX standard. This computer uses the

Debian ARM 8 so that users can enjoy the full range of Debian software, and benefit from its strong community

of developers and shared documentation. With Debian ARM, the UC-8410A-LX supports both native and cross

compilation, making programming on the computer easier and more straightforward.

The UC-8410A-LX series image is partitioned into bootloader and Linux kernel, backup root file system, and

root file system. Refer to the following image partition table for details:

Partition

System Content Partition Format Partition Size

1 Bootloader and Linux kernel W95 FAT32 32 MB

2 Backup root file system EXT4 128 MB

3 Root file system EXT4 Rest of the capacity

The default file system format of the UC-8410A series is EXT4, which is a journaling file system for Linux,

developed as the successor to EXT3. A journaling file system keeps track of the changes before committing

them to the main file system. In the event of a system crash or power failure, journaling file systems are

quicker at bringing back the computer online and less likely to get corrupted.

Software Packages

Most of the software packages come from the Debian community, whereas the unique features of the

UC-8410A-LX series, such as the diagnostic LED and wireless connection, are supported by Moxa. Refer to

Appendix A for software packages installed by default and the Package Management section for information on

managing the software packages installed on your UC-8410A-LX computer.

Connecting to the UC-8410A-LX

You will need access to a notebook computer or a PC to connect to the UC-8410A-LX and log on to the

command line interface. There are two ways to connect to the UC-8410A-LX: through a serial console cable or

through an Ethernet cable. Refer to the UC-8410A Hardware User’s Manual for instructions to set up the

physical connections for your computer.

The default login username and password are:

Username: moxa

Password: moxa

The username and password are the same for all serial console and SSH remote log in actions. The

root

account login is disabled until you manually create a password for the account. The user

moxa is in the sudo

group, which means that this user can use the

sudo command to run system-level commands. Additional

details on using the

sudo command are available in the Sudo Mechanism section.

ATTENTION

For security reasons, we recommend that you disable the default user account

after the initial set up is

complete

and create your own user accounts.
