Subject to errors and modifications

7.1.4 ...using RARP-Server (UNIX only)

Working with an RARP server enabled under UNIX is based on
entries in the configuration files

/etc/ethers

and

/‘etc.hosts

. First

add a line to

‚/etc/ethers

with the assignment of Ethernet address

of the Web-IO to the desired IP address. In

/etc/hosts

the link is

made with an alias name. After you connect the device in the
network segment of the RARP server you can assign the desired
IP address to the device over the network.

Example:

Your Web-IO has MAC address EN=00C03D0012FF (sticker on
the device). You want to give it IP address 172.0.0.10 and the alias
WT_1.

Entry in the file

/etc/hosts:

172.0.0.10 WT_1

Entry in the file

/etc/ethers:

00:C0:3D:00:12:FF WT_1

If the RARP daemon is not yet enabled, start it using the command

„rarpd -a“

arp -s <IP-Adresse> <MAC-Adresse>

e.g. under Windows:

arp -s 172.0.0.10 00-C0-3D-00-12-FF

e.g. under SCO UNIX:

arp -s 172.0.0.10 00:C0:3D:00:12:FF

Now ping the device again (in our example you would ping
172.0.0.10). The IP address is not stored in the non-volatile
memory.

This method is only usable if no IP address has yet been

assigned to the Web-IO, i.e. the entry ius 0.0.0.0. To
change an already existing IP address you must use the

configuration menu from your browser or use WuTility.
