CHAPTER 12: USING THE D400 LOCAL CONFIGURATION UTILITY
D400 SUBSTATION GATEWAY INSTRUCTION MANUAL GE INFORMATION 151
Configure sync manager
The Configure Sync Manager utility can be used to securely copy files from a location on
your D400 device to a specified directory on a remote device. The utility monitors the
specified local directory for changed or added files. To reduce bandwidth demands on
your network, only files found to have been changed or created since the last
synchronization are transferred. This utility employs the Linux-based rsnyc command to
perform this function.
You can configure the settings of the Sync Manager through the
Sync Manager
menu.
The Sync Manager settings are described in Table 42.
Table 42: Sync Manager setting descriptions
Table 43: Settings for each sync set
Setting Description
Enable Sync Manager Use this command to enable the Sync Manager application. This
command deletes the old pair of Public-Private Keys and generates
a new pair of Public-Private Keys.
The existing/newly generated keys are available at:
/mnt/datalog/SSHKeys/SyncMgr/id_rsa.
This command provides an option to configure the “sync set”
through the “rsync” feature. Rsync is a software utility and network
protocol for Unix-like systems (with a port to Microsoft Windows)
that synchronizes files and directories between one location and
another location while minimizing data transfer. It also includes the
option to provide encrypted transfer by using the SSH.
Generate SSH Authentication
Keys
Files from the D400 are securely copied to the remote device over an
SSH connection. To facilitate authentication on this link, a private/
public key pair must be generated and transferred to the remote
device.
When a key set is generated, the files are stored in
/mnt/datalog/
SSHKeys/SyncMgr/ . You should copy the public key file (id_rsa.pub)
from this location and store it in the appropriate location on the
remote device. Refer to the user documentation provided with your
remote device to determine where this location is. Do not remove
the private key from this location since the Sync Manager will not be
able to establish a secure connection.
You must copy the public key (or host fingerprint) from any remote
device you are connecting to into the /mnt/datalog/SSHKeys/
SyncMgr/known_hosts/ folder on your D400. This file likely has a
“.pub” extension; refer to the user documentation provided with your
remote device to determine where the key can be obtained.
Configure Sync Sets Up to 8 sync sets can be created at any time. Table 43 lists the
settings can be configured for each set:
Setting Description Range
Sync Set ID A unique number used by the system to
identify the sync set. Not editable;
automatically assigned.
Auto-incremented from 1. Once
a number has been assigned, it
is never reused.
Destination IP
Address
The IP address of the remote device where
the files are to be copied.
Valid IPv4 address
Destination User
Name
The username used for SSH authentication
on the remote system.
1 to 128 ASCII characters
Source Path Name The absolute directory pathname that is
synched to the remote device.
2 to 120 ASCII characters
pointing to a valid location on
the D400 file system
Destination Path
Name
The absolute directory pathname that the
files are to be copied to
2 to 120 ASCII characters
