About DHCP

Dynamic Host Configuration Protocol - DHCP

Address allocation with DHCP works according to the client-server principle. The client

requests the IP address configuration from a DHCP server which looks up the

requested data in its database.

The DHCP server can allocate the following settings to the Thin Client:

• IP address

• Sub-net mask

• Standard gateway

• DNS server address

Auto config via DHCP

In the case of automatic allocation, the client sends its address request to all network

participants. The DHCP server responds with a data package that contains, in addition

to a possible free IP address and the client's MAC address, the sub-net mask and the

IP address and ID of the server. The client takes the required data from the response

and informs the DHCP server. The server confirms the TCP/IP parameters and sends

additional information such as the DNS server back to the client. The DHCP server

stores the automatically allocated address together with the MAC address in the

database. This allocation is permanent.

Activating VNC server system on the host

The following explains the procedure for the TightVNC server.

In order to be able to establish a VNC connection, the VNC server system must be

activated on the host. The VNC service acquires the IP address needed for this

connection from the settings of the PC's network connection. Depending on the

configuration, the IP address is specified manually or allocated by a DHCP server. In

the firmware's address book, this IP address is defined as the server IP of the VNC

connection.

The way this connection is established depends on the settings of the VNC server and

can either be

• a direct connection that is not password-protected

• a connection with VNC password

• a connection with Windows password

9.2.1

VNC server parameters

The following parameters are necessary to configure the VNC connection. The actual

name may vary depending on the VNC server system used.

VNC server address

The VNC server address is the same as the server IP address or the server name.

The VNC server systems usually have several ways to find out the address with which

the server can be addressed in the network.

In addition to the IP address, port numbers can be allocated in the settings of the VNC

server, with which the server can be addressed in the network.

The target address of the Host PC must be located in the network of the Thin Client or

must be contactable from the Thin Client.

Remote HMI

Manual

Ports

Accept connections on port

Defines the server connection port for data

transmission (standard port 5900).

If you are using a different port due to network

conflicts you need to configure this port. Check the

settings of a firewall.

VNC password

VNC server applications authenticate users of a VNC connection via a password. The

following password procedures are available:

None

No password is defined. The VNC server on the

host allows access to each remote PC (Remote

HMI) requesting a VNC connection via its address.

VNC password

Defines one or more passwords (depending on

VNC server application) which the VNC server

system requests from the Client for authentication

purposes.

Windows password

Uses the Windows access authentication. The VNC

server system grants the client access to the host if

logged on with the valid Windows password.

Single sign on

Uses Windows access authentication and

authentication via Windows-based login. The VNC

server system grants access to the client if the user

has entered a valid Windows login.

Encryption

Most VNC servers use encryption to protect the transmission of image, mouse and

keyboard data from unauthorised access.

Always on

Data is always encrypted

Prefer on

Data is always encrypted unless the Thin Client

requests no encryption (standard). This setting is

necessary if the configuration requests no

encryption.

requests encryption. This setting is necessary if the

configuration requests encryption.

Prompt local user to accept connections

Allows the host user to accept or reject a connection request. Since the host is usually

used for direct remote access, this setting is not relevant for the Thin Client

connection.

started. If this function is not activated, the remote access must be explicitly started

after a system start of the host PC.
