Installing a floating license for AIX logins
Useful tools to show server, product, and license information
This document discusses the installation of a floating license for AIX
logins and applies to AIX Versions 4.1 and 4.2.
Setting up the iFOR/LS "floating" license includes four major steps:
- Install the iFOR/LS filesets.
- Configure iFOR/LS on the server.
- Start the server daemons.
- Enable the floating license on the server and the clients.
llbd - local location broker daemon
glbd - global location broker daemon
netlsd - processes request for licenses
monitord - monitor licensed login processes
Daemons are started in a specific order:
llbd -> glbd -> netlsd
Daemons are shut down in the reverse order:
netlsd -> glbd -> llbd
NOTE: Stopping the daemons in the wrong order can corrupt NetLS
To install and enable AIX floating licenses, perform the following steps.
- Install the necessary filesets from the server install media. These
- bos.sysmgt.loginlic -- License Management (chlicense, monitord)
- bos.ifor_ls.client -- iFOR/LS License System Client Utilities (GUI tools to
show server/product/licenses information)
- bos.ifor_ls.server -- iFOR/LS Server Utilities (netlsd)
- bos.rte.ifor_ls -- iFOR/LS Libraries
- bos.net.ncs -- Network Computing System (glbd, llbd)
- Use the following steps to configure the server.
- Run the following shell script:
The steps this script provides are as follows:
- Entries are added to /etc/inittab to automatically start /etc/rc.ncs at
reboot. The /etc/rc.ncs starts the llbd and glbd daemons.
- Entries are added to /etc/inittab to automatically start /etc/rc.netls at
reboot. The /etc/rc.netls starts the netlsd daemon.
- It configures the NCS cell environment.
- It creates the /usr/lib/netls/conf/netls_first_time which starts iFOR/LS
daemons the first time. After that, the daemons will start automatically at
- When prompted by the following questions, give the following answers:
Do you want the "llbd" started automatically when the machine boots?
Do you want "netlsd" started automatically when the machine boots?
(This question may be asked.) There exists an initialized database
already for the glbd. Do you wish to use that database when starting the "glbd"
You will be shown a listing of all the cells that your machine can identify.
If you are setting up your machine in a new alternate cell, none of this
information is relevant to you. If you intend to join an alternate cell that
has already been established, note the cell number when it is displayed on
the screen. Please note that the cell numbers may be assigned differently each
time netls_config is run.
You will have three or four options:
- Continue with installation without choosing a cell name.
- Use the default for the system cell name.
- Create a new alternate cell for the system cell name.
- Choose an existing alternate cell for the system cell name.
Please indicate your choice (1, 2, 3, or 4):
- Choose 1 if you do not know what configuration you want and just want to
quit. You will have to re-run netls_config later.
- Choose 2 only if your site administrator approves of the use of the
default cell, or if you are on a standalone machine. Remember that bridging of
cells is not allowed.
- Choose 3 if you are going to run your server in a brand new alternate
cell. This is the recommended selection to use if you are unsure.
- Choose 4 if you are going to join your server to a cell that has already
been established. You will then be prompted for the number of the alternate
cell you want to join. Enter that number now.
- You are done with the netls_config script. It has created a secondary
shell script called /usr/lib/netls/conf/netls_first_time.
- Run the netls_first_time script. This will start the daemons needed for
serving license requests. This script only needs to be run once.
After the first time, the daemons can be started with the startsrc command.
They must be started in the correct order (llbd, then glbd, then
exact commands are:
startsrc -s llbd
startsrc -s glbd
startsrc -s netlsd
This may also be accomplished by running the command:
- If at some point you have to reconfigure your server for a different cell,
stop the llbd, glbd, and netlsd daemons and then re-run the
script, followed by the netls_first_time script.
To stop the daemons manually, use the stopsrc command. The daemons must be
stopped in the reverse order that they were started. The exact commands are:
stopsrc -s netlsd
stopsrc -s glbd
stopsrc -s llbd
Or you can use the command:
- Now that your license server is up and running, you will need to enable
floating licenses. On the command line, issue the command:
chlicense -f on
Or use the SMIT utility under:
The preceding executions would start monitord and add an entry in /etc/inittab to
automatically start monitord at reboot.
If you get the error message Could not enable floating license, check if
the /etc/security/monitord_lock file exists. This file prevents multiple
copies of monitord from being run. But if monitord is stopped abnormally,
remove this file manually before running chlicense -f on.
- Next, install the AIX floating user licenses by means of the following SMIT
The preceding step creates the floating license file, AIX.FLOAT, under
To change the number of AIX floating licenses installed on a system, use
the following SMIT menus:
- If your server machine has the file /etc/ncs/glb_obj.txt, then all users
that need licenses from your server must copy that file to their client
machines. The file contains the identifier for the alternate cell.
Example /etc/ncs/glb_obj.txt file:
- If a client machine is on a different subnet than your server machine, then
the client machine must have the file /etc/ncs/glb_site.txt. The contents of
the file will identify the server machine. For example, if the server machine
is myserver.mynet.mycompany, then the glb_site.txt file will contain the
The glb_site.txt file can also specify the IP network address of the server
machine. For example, if the IP address of the host machine is 111.22.333.444,
then the glb_site.txt file will contain the line:
Example /etc/ncs/glb_site.txt file:
- The fileset bos.ifor_ls.client contains some useful commands and GUI tools
to display server, product, and license information.
- /usr/lib/netls/ark/bin/ls_admin displays server, vendor, product, and license
information. For AIX login floating license, the product name should say
AIX User License [4.x];
- The license information includes the number of concurrent access licenses
and the expiration dates, as well as the server IP address and the socket port
- /usr/lib/netls/ark/bin/ls_tv verifies that license servers are working. It
displays the fully qualified names of the active license servers along with the
product names and the iFOR/LS version numbers.
- /usr/lib/netls/ark/bin/ls_targetid shows the CPU serial number of the
- /usr/lib/netls/ark/bin/ls_stat shows the status information on network
licenses. It has both command line and GUI interface.
- /usr/lib/netls/ark/bin/ls_rpt generates reports on license server events.
This command can be used to track and monitor license usage, amount and causes
of rejected license requests.
