The Samsung CLP-320 printer's static ip 192.168.1.139 was set about 10
years ago to work on a lan using 192.168.1.x addresses. Last week the
lan's router failed and was replaced with a Netgear r6700 router using
192.168.2.x addresses. The printer is now inaccessible from the lan.
Cups Administration says the printer address can be set using its MAC
address:
Configuring the IP Address Using DHCP
The DHCP protocol is the usual way of setting the IP address of a
printer on a managed network. Using the standard dhcpd(8) program
supplied with UNIX you simply need to add a line to the /etc/dhcpd.conf
file:
host/hostname/ {
hardware ethernet/mac-address/;
fixed-address/ip-address/;
}
Make sure that the hostname you use is also listed in the /etc/hosts
file or is registered with your DNS server.
apt-cache search dhcpd finds udhcpd. My pc's system is Debian Stretch.
There is a file /etc/dhcp/dhclient.conf but no file /etc/dhcpd.
Is it possible to access the printer and change its address to one in
192.168.2.x or to reset it to use dhcp?
The daemon 'dhcpd' is package 'isc-dhcp-server'.
Can't you change the IP of your ISP router to use the subnet 192.168.1.*?
One way to change the IP of your printer would be to directly connect a
computer to your printer and set a fix address on the computer in the
same subnet as the printer.
Then you can change the IP of your printer.
Using the 'dhcpd' and 'named' ('isc-dhcp-server, isc-bind) is one option
but 'dnsmasq' is a simpler way to do the same.
