Printing to NETPrint at AIX 3.2.5

Overview

Setting up printing for AIX 3.2.5 is a two-step process.

1. Create a remote queue to print to the box.
2. Set up a virtual printer to print to the remote queue.

Creating a remote queue at AIX 3.2.5

1. Add an entry to the /etc/hosts file as follows:

        123.1.1.2         netp1
   

   • 123.1.1.2 should be changed to the printer IP address from the test page.
   • Change netp1 to the printer host name you will give the NETPort box.

2. Test the TCP/IP connection:

       ping netp1
   

   If this does not show a successful connection, fix the communication problems before continuing with adding a printer.

3. Enter smit spooler. The short path is smit mkrque.
4. Make the following selections:
   • Select Manage Remote Printer Subsystem.
   • Select Server Services.
   • Select Host Access for Printing.
   • Select Add a Remote Host.
5. Fill in the screen:

                                  Add a Remote Queue
   
   Type or select values in entry fields.
   Press Enter AFTER making all desired changes.
   
                                                       [Entry Fields]
   * NAME of queue to add                           [netp1]
     ACTIVATE the queue?                             yes              
     Will this become the DEFAULT queue?             no              
     Queueing DISCIPLINE                             first come first serve 
     ACCOUNTING FILE pathname                       []
   * DESTINATION HOST for remote jobs               [netp1]
   * Pathname of the SHORT FORM FILTER for queue    [/usr/lpd/bsdshort]  
       status output
   * Pathname of the LONG FORM FILTER for queue     [/usr/lpd/bsdlong]  
       status output
   * Name of QUEUE on remote printer                [PORT1]
   * NAME of device to add                          [netpd]
   * BACKEND PROGRAM pathname                       [/usr/lpd/rembak]
   

   You should add the following information as indicated in the preceding discussion.
   • Name of queue. This is the queue that will send data to the printer. This is not the queue to which you will print. You will set virtual printers to print to this queue.

   • DESTINATION HOST. This is the host name from /etc/hosts entered in step 2.
   • Change the FILTER names to reflect BSD and not AIX.
   • The remote server queue PORT1 or PORT2 determines the port on the NETPort box.
   • The device name is a dummy name; keep it five or fewer characters in length.
6. Press Enter to add the queue.
7. Test print to the queue. Enter:

       lptest 10 10 | qprt -Pnetp1
   

   You should be able to print but there is no virtual printer. You will add the virtual printer to control attributes next.

Creating a double queue at AIX 3.2.5

Overview

Although you should be able to print, it is often desirable to add a virtual printer to control output to the printer such as pitch, paper drawer, or landscape printing. This can be done by double queueing. Create a virtual printer that sends its output to the remote queue that you just created.

Setup

1. Create a unique file in the /dev directory for a lock file. Enter:

       touch /dev/netp1
   

   Do not use /dev/null as prescribed in the Digital Products instructions. This blocks queues on multiple boxes if they are all set up this way.

2. Enter mkvirprt.
3. Choose 1 Printer or Plotter Attached to Host.
4. Enter the device name or ! to exit. For example, (lp4) -> netp1.
   Use the file you created in /dev. Do not type /dev/.
5. Choose the printer type, for example, IBM 4039.
6. Header pages wanted? Enter n, a, or g.
7. Trailer pages wanted? Enter n, a, or g.
8. Enter print queue name or ! to bypass the configuration. For example, -> (ps) ps1.
9. Do you want this to be the default queue? Enter y or n.
10. Enter print queue name or ! to bypass the configuration. For example, -> (pcl) pcl1.
11. Do you want this to be the default queue? Enter y or n.
12. Press Enter to add the queue.
13. Change the virtual printer to print to the remote queue. Complete the following steps:
    • Enter lsvirprt.
    • Choose the pcl1 created earlier.
    • Change the mo attribute as shown below where netp1 is the remote queue added earlier.

           To LIST attributes, enter AttributeName1 ... (* for all attributes)
           To CHANGE an attribute value, enter AttributeName=NewValue
           To FORMAT and EDIT an attribute value, enter AttributeName~v
           To EDIT the attribute file, enter ~v
           To terminate, press Enter:  mo=qprt -Pnetp1
      

14. Test print to the queue. Enter:

         lptest 10 10 | qprt -Ppcl1
    

15. Make any other changes, such as changing the pitch to 17, using the command lsvirprt as described earlier:

    To LIST attributes, enter AttributeName1 ... (* for all attributes)
    To CHANGE an attribute value, enter AttributeName=NewValue
    To FORMAT and EDIT an attribute value, enter AttributeName~v
    To EDIT the attribute file, enter ~v
    To terminate, press Enter:  p=17
    
    Name    Description                                          Value
    _p      Pitch (characters per inch)                          17
    

You should now have a queue to which you can print and make changes.

Setting up AIX as a bootp server

NOTE: This procedure has not been tested.

Overview

Setup

1. Edit /etc/bootptab and add the following entry:

    netp1:hn:ht=ether:ha=0800095e9e10:ip=5.1.1.5:
          sm=255.255.255.0:gw=5.1.1.152:
   

   • If there is a file to download, include it with bf=/usr/local/NETPboot.
     
   • The ht will have to be changed to tok for token-ring.
   • The ha is the hardware address from the NETPbox test page.
   • ip is the IP address.
   • gw is the gateway.
   • sm is the subnet mask.

2. Enable bootpd and tftp in the /etc/inetd.conf file by uncommenting the following lines. Remove the # sign at the beginning of each line.

     bootps  dgram   udp     wait    root    /etc/bootpd bootpd
     tftp    dgram   udp     wait    nobody  /etc/tftpd tftpd -n
   

3. Refresh the inetd daemon. Enter:

     inetimp   
     refresh -s inetd
   

4. Turn on and off the NETPort box.
5. Print a test page to see if the IP address was loaded.
   If the address was not loaded, stop bootpd and rerun bootpd in debug mode. The most common problem is entering the wrong hardware address. The debug mode will show you the address being broadcast.
6. ping the address.

   Setting up as an AIX ARP server

   AIX will also support ARP download of IP addresses. Use:
   1. arp -s (IP address of NETS\JETX) (LAN address of NETS\JETX)

      For example:

          arp -s  192.00.20.10   01-12-23-FE-A2-00
      

      NOTE: You must use dashes (-) to separate the numbers of the LAN address. In this example, the IP address 192.00.20.10 is the IP address we are assigning to the NETS\JETX unit.

   2. See the arp table with the command arp -a.
   3. Enter ping 192.00.00.10. At this time, there may be no reply.
   4. Reset the NETS/JETX by resetting the power.
   5. Enter ping 192.00.00.10. This time there should be a reply.

      Once you get a successful ping, the NETS/JETX has its IP address.

   ---

   Telnet configuration of the NETS/JETX box

   1. Go to the $ or # prompt in AIX and telnet to the NETS/JETX.
      • Enter tn netp1 where netp1 is the host name of the NETS/JETX box.
      • The login and password is sysadm.
   2. When the main menu appears, select option 1 to configure the remaining IP parameters (subnet mask and default gateway if applicable).
   3. Press Enter to get back to main menu.
   4. Choose option 3 to disable any protocols that you are not using.
   5. Go back to the main menu, and choose option 2, LPD Printers, to set the type of output. If you receive garbled output, increase the strobe to 5 or 10 microseconds.
   6. Save changes and reset the NETS/JETX. You should now be ready to proceed with the AIX setup steps.

   Additional information

   AIX support is only responsible for setting up the remote queue. Digital Products is responsible for making this work with their product.

   Some of the information needed was obtained from Digital Products Technical Support Bulletin TSB 2004, TSB 2011, and TSB 2002, obtained from the Web page listed in the References section.
