You use a cpuID whenever you communicate with another computer on the network. (See the AlphaNET
User’s Guide for examples.) By creating a network ersatz file, you can assign unique, easy to remember
names to represent the cpuID number for each computer on the network, including your own. See
“Defining Ersatz Names for Your Network” in Chapter 3 for more details. Finding out the cpuID for a
particular computer is easy. Just create and run the BASIC program in “Determining Your cpuID
Number” in Chapter 3 or use the NTSTAT/C command and look for the group and node number.
The name of the file containing the network ersatz information can be up to six characters in length,
followed by a .ERZ extension. Since our example network uses Ethernet and we used 100 as a network
number, we’ll create a file (on both computers) called ETH100.ERZ.
Notice in Figure 1 that the two computers each have a name printed above them; DAVE: and HAL:.
Let’s define a network ersatz file that will support these two computers.
The information you enter into the file will look something like this:
DAVE:=1677787137-
HAL:=1677787138-
The file is identical for both computers. The name assigned to the cpuID number can be up to six
characters and it must be followed by a colon (:).
6. Create a SYSNAM.DAT File
The SYSNAM.DAT file contains a descriptive phrase describing your computer. This phrase is displayed
when a user connects to your computer as a virtual terminal. It is also displayed when the network status
program NTSTAT is run.
The AlphaNET User’s Guide contains detailed information on NTSTAT and virtual terminal
capabilities.
The SYSNAM.DAT file you create will contain a single line of data limited to 30 characters. Since the
NAME parameter in our hypothetical network was entered as
Accounting Network , we’ll assume
the two computers in our network have accounting functions. We’ll give the computer called HAL: a
SYSNAM.DAT file that looks like this:
Accounts Receivable
We’ll make a SYSNAM.DAT file for the computer called DAVE: that looks like this:
Company Payroll
If you run NTSTAT, the resulting display looks something like this:
