The IP address is now stored in non-volatile memory.
This method can only be used if no IP address has yet

been assigned to the IP-Watcher, i.e. the entry is 0.0.0.0.
To change an already existing IP address, you must open the
configuration menu from the browser or select the serial path.
8.3.2 RARP server (UNIX only)
Working with an RARP server enabled under UNIX is basded on
entries in the configuration files
/etc/ethers
and
/etc/hosts
.
First expand
/etc/ethers
by one line with the assignment of the
Ethernet address of the IP-Watcher to the desired IP address. In
/etc/hosts
the link with an alias is then determined. After you
have connected the device in the network segment of the RARP
server, you can use the network to assign the desired IP
address to the device.
