Platform LSF Licensing
All client hosts belonging to a domain with the address 100.172.1.13 will be allowed
access. All client hosts belonging to domains starting with 100, then any number,
then a range of 30 to 54 will be allowed access. All client hosts belonging to domains
starting with 124, then from 24 onward, then 1, then from 0 to 34 will be allowed
access. No IPv6 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE=12.23.45.*
All client hosts belonging to domains starting with 12.23.45 are allowed. No IPv6
hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.*43
The * character can only be used to indicate any value. In this example, an error will
be inserted in the LIM log and no hosts will be accepted to become LSF floating
clients. No IPv6 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.*43 100.172.1.13
Although one correct address range is specified, because *43 is not correct format,
the entire line is considered not valid. An error will be inserted in the LIM log and
no hosts will be accepted to become LSF floating clients. No IPv6 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE = 3ffe
All client IPv6 hosts with a domain address starting with 3ffe will be allowed access.
No IPv4 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE = 3ffe:fffe::88bb:*
Expands to 3ffe:fffe:0:0:0:0:88bb:*. All IPv6 client hosts belonging to domains
starting with 3ffe:fffe::88bb:* are allowed. No IPv4 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE = 3ffe-4fff:fffe::88bb:aa-ff 12.23.45.*
All IPv6 client hosts belonging to domains starting with 3ffe up to 4fff, then
fffe::88bb, and ending with aa up to ff are allowed. All IPv4 client hosts belonging
to domains starting with 12.23.45 are allowed.
FLOAT_CLIENTS_ADDR_RANGE = 3ffe-*:fffe::88bb:*-ff
All IPv6 client hosts belonging to domains starting with 3ffe up to ffff and ending
with 0 up to ff are allowed. No IPv4 hosts are allowed.
Checking that security is enabled
Take this step after you have configured security. You are shown how to check that
security has been configured properly.
After you configure FLOAT_CLIENTS_ADDR_RANGE, check the master LIM
log file on the LSF master host (LSF_LOGDIR/
lim.log.master_host_name) to
make sure this parameter is correctly set. If this parameter is not set or is wrong, this
will be indicated in the log file.
Verify LSF floating client license is working
Perform this procedure after setting up your floating client license to verify that
your floating client license is enabled.
1 Start a cluster.
2 Run the
lshosts command from a host listed in lsf.cluster.cluster_name:
