Updating Hosts file
Once the IP address is defined, the file /etc/hosts needs to have
this IP address and host name added. For example:
132.147.69.4 Allison
Testing the connection
Use ping to test if the Ethernet Card is responding. For example,
send the following command:
PING Allison
or
PING 132.147.69.4
If the card responds, you are ready to print. If not, check the IP
address on the status page and details in /etc/hosts file.
Note:
If your host does not support any devices where the first three numbers of
the internet address are different from the network you are working with,
then you may temporarily change the Net Sub Mask in your-file ‘hosts.‘
The file is located on the file server as well as on the workstation you are
sending the print job from. After you have set
up
the network interface,
change the Net Sub Mask back to its previous setting. A Net Sub Mask of
000.000.000.000 will allow any inter-net address on the system.
Printing via lpr
Once the internet address has been assigned to the Ethernet Card,
all the host computers that will be using it to print through need to
have its address added to their “telephone directories.” The
method for achieving this differs from system to system, and so
the systems administrator should be consulted.
