2 Assigning the IP address

The Com-Server is factory set to IP address 0.0.0.0. Before you can make

the entry in the Com-Server, you need to specify an IP address that is valid

for your network. You system administrator will provide you with this. If

you have only a small network with no routing, use the IP address of your

PC and simply change the last digit. The IP address must be unique within

the network!

W&T Assigning the IP address

2.1 Configuring network parameters with WuTility

The Windows tool WuTility version 3.0 and higher allows not only inventorying of Com-Server and Web-IO installations, but also convenient assignment of the following network-side basic parameters:

• IP address

• Subnet mask

• Gateway address

• Activating/deactivating BOOTP/DHCP

• Activating/deactivating Web-Based-Management

Assigning requires that the PC and Com-Server be in the same subnet. In firmware revision 1.45 the function is independent of the current address settings in the Com-Server, i.e. even changes to parameters not matching the network are easily made. Any system password which has been set must however in this case be known.

Downloading and installing WuTility

The most current version can always be found at our Web site under the following address:

http://www.wut.de

From there use the menu tree on the left side to navigate:

Products & Downloads r Com-Servers r Software Tools

After unzipping the ZIP file, begin installation by doubleclicking on the file setup_us.exe. WuTility is started from

Start r Programs r W&T Software Toolkit r WuTility

Starting the assignment dialog

First be sure that both the Com-Server and the computer you are using are connected to the same network and are in the same subnet. When started, WuTility automatically searches the

W&T Assigning the IP address

Subject to error and alteration

local network for connected W&T network devices and creates an inventory list. This search process can be repeated manually as often as desired by clicking on the Scan button:

Within the inventory list you can identify the desired Com-Server based on its MAC address. For initial installations its IP address is 0.0.0.0.

Select the Com-Server and click on the IP address button:

Enter the desired values for IP address, subnet mask and gateway address in the corresponding fields and then click on the Next button.

W&T Assigning the IP address

In the following window you can activate the BOOTP client and the Web-Based-Management of the Com-Server.

To prevent unintended address assignments or changes,

we recommend deactivating the DHCP, BOOTP and RARP protocols if they are not expressly used in the respective network environment. Com-Servers with incorrectly assigned IP addresses can be easily found after the fact using the scan function of the WuTility management tool and reconfigured.

Clicking on the Next button assigns the network parameters to the Com-Server. All columns in the WuTility device list are filled with information.

This concludes the network-side startup of the Com-Server, and for many applications – such as use together with the COM Port Redirector – no further settings are necessary. Special modes or serial parameters can be set using the telnet configuration menu or, if Web-Based-Management was used, with the help of the Internet browser. To do this, click on either the Telnet or

Browser button:

Changing network parameters is protected by the

system password. To prevent improper access, we recommend assigning a system password for any Com-Servers in use.

Additional information can be found in the section Configuration Accesses for the Com-Server.

W&T Assigning the IP address

2.2 Assigning the IP using the ARP command

This method can only be used if the Com-Server does not already have an IP address, i.e. the entry is

0.0.0.0. To change an IP address, use one of the other methods described in this section or use the configuration menu over Telnet.

Required is a computer which is located in the same network segment as the Com-Server and which has TCP/IP protocol installed. Read off the Ethernet address of the Com-Server from the sticker on the side of the housing:

58xxx [Model]

EN=00c03d004a05

OK xxxxxx

Ethernet address

Insert a static entry into the ARP table of the computer using the following command line:

arp -s [IP address] [MAC address]

e.g. under Windows:

arp -s 172.16.231.10 00-C0-3D-00-12-FF

e.g. under SCO UNIX:

arp -s 172.16.231.10 00:C0:3D:00:12:FF

Next use the following command line under Start r Run to start a Telnet session on the configuration port of the ComServer with the desired IP address:

telnet 172.16.232.10 1111 [

Return

]

The IP addresses must be without leading zeros in

all Windows environments. Otherwise the entry is incorrectly interpreted by the system and an incorrect IP address is assigned to the Com-Server.

The IP address must be unique within the network.

Older Windows systems only accept a static entry if there is a dynamic one already present. Here you should first ping another network station.

W&T Assigning the IP address

Subject to error and alteration

The Com-Server takes the IP address of the first network packet sent to it as its own and saves it in non-volatile memory. The Telnet connection will be established and the configuration menu is displayed in the Telnet window. All further settings are made here (see Basic configuration of the Com-Server).

W&T Assigning the IP address

2.3 Serial assigning of IP, subnet mask and gateway

After a Com-Server reset a time window of around 1-2 seconds is available, during which you can assign a new IP address, subnet mask and gateway address by entering at least 3 „x“.

In contrast to the ARP method described above, this

serial method functions regardless of whether the Com-Server already has an IP address or not. The procedure can be repeated as often as desired. Therefore use this method if you don‘t know the IP address or have forgotten it. Appendix D contains the detailed procedure under Windows using HyperTerminal.

First connect the serial port A of the Com-Server to a computer. For a standard PC or laptop, you will need a

crossed RS232 cable (=Null modem cable, see RS232 interface).

The serial transmission parameters of the terminal program you use should be set to 9600 baud, no parity, 8 bits, 1 stop bit, no handshake. Reset the Com-Server by interrupting the power. When the green status LED lights up, enter the letter „x“ at least three times on the terminal, until the Com-Server returns the prompt IPno.+<Enter>.

Use the usual format (xxx.xxx.xxx.xxx) to enter the IP address, and end the entry by pressing <Enter>. If the entry was accepted, the acknowledgement is the assigned IP address. Otherwise you will get a FAIL message followed by the last current IP address.

All other settings such as gateway address, subnet mask etc. are done through the Telnet configuration menu (see Basic configuration of the Com-Server).

W&T Assigning the IP address

Subject to error and alteration

2.3.1 Assigning of subnet mask and gateway address

Together with the IP address, the subnet mask and gateway address can also be assigned serially. The entry is separated by commas and follows the IP address. Entering as shown in the following example will assign IP address 172.17.231.99, subnet mask 255.255.255.0 and gateway 172.17.231.52 to the Com-Server

IP no.+<ENTER>: <- Com-Server

172.17.231.99,255.255.255.0,172.17.231.52 -> Com-Server

172.17.231.99,255.255.255.0,172.17.231.52-1 <- Com-Server

2.3.2 Deactivating DHCP/BOOTP/RARP

The DHCP/BOOTP/RARP function of the Com Server can be turned off as part of assigning the IP address serially. We recommend making use of this at all times except where use of DHCP, BOOTP or RARP is expressly required. To deactivate the DHCP/BOOTP/RARP client enter the option „-0“ (zero) directly appended (no space!) to the IP address and confirm with <Enter>.

• -0

DHCP, BOOTP and RARP = OFF

• -1

DHCP = OFF, BOOTP and RARP = ON

• -2

DHCP = ON BOOTP and RARP = OFF

Example: Deactivation of DHCP, BOOTP and RARP

xxx - > Com-Server IP no.+<ENTER>: <- Com-Server

172.17.231.99-0 - > Com-Server

172.17.231.99 <- Com-Server

An explanation of the basic terms and concepts for addressing in the internet and using DHCP and BOOTP can be found in our manual TCP/IP- Ethernet and Web-IO.

W&T Assigning the IP address

This function can later be reactivated through the Telnet configuration under SETUP System r SETP TCP/IP r BOOTP Client.

To prevent unintended address assignments or changes,

2.3.3 Serial activation of Web Based Management

To further configure the Com-Server you can use either Telnet protocol or an Internet browser, although only Telnet is an option in the Com-Server as shipped from the factory. You can activate Web Based Management as part of the serial IP assignment. To do this, enter +w[Portno.] directly after the IP address or address string. Here Portno. is the desired TCP port in decimal format.

Example 1: Deactivating DHCP/BOOTP/RARP and activating Web Based Management on TCP port 8080.

xxx - > Com-Server IP no.+<ENTER>: <- Com-Server

172.17.231.99,255.255.0.0,172.17.231.52-0+w8080 -> Com-Server

172.17.231.99,255.255.0.0,172.17.231.52-0+w8080 <- Com-Server

Example 2: Activation of Web Based Management on TCP port

80. The status of DHCP/BOOTP/RARP remains unchanged.

xxx - > Com-Server IP no.+<ENTER>: <- Com-Server

172.17.231.99+w80 -> Com-Server

172.17.231.99- 1 < - Com-Server

W&T Assigning the IP address

2.4 Assigning the IP using DHCP protocol

Many networks use DHCP (Dynamic Host Configuration Protocol) or its predecessor described in the following section for centralized and dynamic assignment of the network parameters. DHCP protocol is activated by the factory default settings, so that in network environments dynamic IP assignment is sufficient for connecting the Com-Server to the network. The following parameters can be assigned using DHCP:

• IP address

• Subnet mask

• Gateway address

• DNS server

• Lease time

To prevent unintended address assignments or changes,

2.4.1 Activating/Deactivating DHCP

The factory default setting is for DHCP protocol active. To deactivate it or to enable it again later, use one of the following options.

• Management-Tool WuTility

Select the desired Com-Server in the device list and click on the IP Address button. In the first dialog box enter the newly assigned network parameters and then click on Continue. In the following dialog BOX deactivate the options BOOTP and DHCP.

W&T Assigning the IP address

Subject to error and alteration

Clicking on Continue then sends the new configuration data to the Com-Server.

• Serial port

As part of serial IP assignment, the following options for deactivating/activating DHCP and BOOTP can be selected directly following the address string:

-0 r Deactivates DHCP and BOOTP

-1 r Activates BOOTP/RARP

-2 r Activates DHCP A detailed description of the procedure can be found in the section on Serial assignment of IP, subnet mask and gateway.

• Telnet or Web Based Management

From the menu branch SETUP System r Setup TCP/IP r DHCP/ BOOTP Client the protocols can be alternately activated and

both deactivated. For detailed information refer to the section Menu: SETUP System.

2.4.2 System Name

To support any automatic updating of the DNS system by the DHCP server, the Com-Server identifies itself within the DHCP protocol with its system name. The factory default setting for this is COMSERVER_ followed by the last three places of the Ethernet address. For example the factory set system name of a Com-Server with the Ethernet address 00:c0:3d:01:02:03 is COMSERVER_010203. The system name of the Com-Server can be changed in the configuration. For additional information refer to the section Menu: SETUP System r System Name.

W&T Assigning the IP address

2.4.3 Lease-Time

The lease time determined and transmitted by the DHCP server specifies the Time-To-Live of the assigned IP address. After half the lease time has expired, the Com-Server attempts to extend the time for the assigned DHCP server and up update the address. If this is not possible by the time the lease time expires, for example because the DHCP server can no longer be reached, the Com-Server deletes the IP address and starts a new cyclical search for alternate DHCP servers for the purpose of assigning a new IP address.

Because of the absent clock, the lease time associated with the current IP address is no longer available after a reset. After the restart therefore a corresponding update request is issued with the original DHCP server. If the latter is not resolvable at this point in time, the Com-Server deletes the IP address and starts a new cyclical search for alternate DHCP servers.

If DHCP is activated, the remaining lease time together with the current IP address is displayed in the menu item SETUP System

r Setup TCP/IP r IP-Address using the format hh:mm:ss.

If after the assigned lease time has expired the DHCP

server is not reachable, the Com-Server deletes its IP address. All existing TCP/UDP connections between the ComServer and other network clients are thereby closed. To prevent such events, we recommend configuring the assigned lease time in the DHCP server to infinite if possible.

W&T Assigning the IP address

Subject to error and alteration

2.4.4 Reserved IP addresses

If the Com-Server is used as a TCP server or UDP peer, it provides services which other clients in the network can also make use of as needed. To open a connection, they of course need the current IP address for the Com-Server, so that in such situations it makes sense to reserve a particular IP address for the Com-Server on the DHCP server. This is generally done by linking the IP address to the unique Ethernet address of the Com-Server, which can be found on the sticker attached to the housing.

Fully dynamic address assignment, whereby the Com-Server gets a different IP address every time it is restarted or after the lease time has expired, only makes sense in network environments with automatic cross-connection between the DHCP and DNS services. This means when a new IP address is assigned to the Com-Server, the DHCP server then automatically updates the DNS system as well. The new address is associated with the respective domain name. If in doubt, consult your system administrator for detailed information about your network environment.

If the Com-Server is configured as a TCP or UDP client and itself actively searches for a connection to server services in your network, dynamic changing IP addresses may be used.

2.5 Assigning the IP using BOOTP protocol

Many networks use BOOTP as predecessor of DHCP protocol for centralized and dynamic assignment of IP addresses. The factory default setting is for BOOTP turned off. You can activate it from SETUP System r SETUP TCP/IP r BOOTP Client. The following parameters can be assigned:

• IP address

• Subnet mask

• Gateway address

• DNS server

To prevent unintended address assignments or changes,

2.5.1 Address reservation

BOOTP protocol is based on fixed reservations of fixed IP addresses for particular Ethernet addresses. This means a ComServer connected to the network only gets an IP address if the latter was previously stored in the BOOTP server. Check with your system administrator for creating this reservation. The Ethernet address of the Com-Server can be found on the housing sticker.

Once the administrator has made the necessary entries, the Com-Server obtains the desired IP address automatically after

each reset. To ensure accessibility of the Com-Server even should the BOOTP server go down, the previous IP address is retained should there be no reply.

2.6 Assigning the IP using a RARP server

UNIX environments especially use RARP protocol for centrally assigning IP addresses. TCP/IP devices that want to obtain an IP address send RARP requests with their Ethernet address as a broadcast over the network.

RARP protocol is coupled to BOOTP protocol in the Com-Server. Activate it from SETUP System r SETUP TCP/IP r BOOTP Client.

Activate the RARP server, and enter the Ethernet address of the Com-Server in the file /etc/ethers and the IP address in the file /etc/hosts.

The Com-Server must be connected to the network in the same segment as the RARP server.

Example:

Your Com-Server has the MAC address EN= 00C03D0012FF (sticker on the unit). You want to give it IP address

• Entry in the file /etc/hosts:

172.16.231.10WT_1

• Entry in the file /etc/ethers:
