Unix NIC Configuration
There are mandatory settings needed before the print server can be detected
on the network, as well as some additional optional settings. This section
offers alternative methods for configuring your NIC and mentions some of the
more common optional settings available.
Mandatory
The NIC must be assigned TCP/IP values of IP Address, Subnet Mask, and
Gateway Value (if required) before setting up and establishing print queues
and logical Unix printers. Refer to Chapter 7, “TCP/IP Configuration” for more
information.
Additionally, the file “
etc/hosts”
on the Unix system (or the DNS server known
to the Unix workstation being set up) must be updated to include the IP
Address and logical name for the NIC, or a DNS server needs to be set with
this information so that the Unix print daemons (software processes) can
communicate with the physical NIC.
Optional
Additional settings, like routing entries, can be configured allowing for
communication across subnets.
Configuration of the NIC can be done from the control panel or through host
commands.
Communicating Across Routers
Since Unix environments rely on TCP/IP to communicate with the NIC,
attention must be paid to routing.
After following one of the NIC configuration methods mentioned (other than
the BOOTP method), you will most likely only be able to communicate with
the print server from the same subnet. This means any host across a router
will not be able to see your NIC. In order to communicate across a router, it is
possible to store a static default router/gateway within the print server so that
any packets destined for another subnet get forwarded to this router
automatically. The router (or series of routers) can then take over ensuring
the packets get to their final destination on another subnet on your network.
To configure a default router/gateway within the NIC:
1. Use the printer front panel to configure the gateway value.
2. Load a Web browser on your Unix station on the same subnet and direct
it to the URL
