Platform LSF Reference Version 6.2

Parameters Section
Platform LSF Reference
486
Specify an IP address or range of addresses, in dotted quad notation
(
nnn.nnn.nnn.nnn). Multiple ranges can be defined, separated by spaces.
If there is an error in the configuration of this variable (for example, an address range is
not in the correct format), no host will be allowed to join the cluster dynamically and an
error message will be logged in the LIM log. Address ranges are validated at
configuration time, so they must conform to the required format.
If a requesting host belongs to an IP address that falls in the specified range, the host
will be accepted to become a dynamic LSF host.
IP addresses are separated by spaces, and considered "OR" alternatives.
The asterisk (*) character indicates any value is allowed.
The dash (-) character indicates an explicit range of values. For example 1-4 indicates
1,2,3,4 are allowed.
Open ranges such as *-30, or 10-*, are allowed.
If a range is specified with less fields than an IP address such as 10.161, it is considered
as 10.161.*.*.
This parameter is limited to 255 characters.
Notes
After you configure LSF_HOST_ADDR_RANGE, check the
lim.log.host_name file 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.
Examples ◆ LSF_HOST_ADDR_RANGE=100
All hosts with a domain address starting with 100 will be allowed access.
◆ LSF_HOST_ADDR_RANGE=100-110.34.1-10.4-56
All hosts belonging to a domain with an address having the first number between
100 and 110, then 34, then a number between 1 and 10, then, a number between 4
and 56 will be allowed access.
Example: 100.34.9.45, 100.34.1.4, 102.34.3.20, etc.
◆ LSF_HOST_ADDR_RANGE=100.172.1.13 100.*.30-54 124.24-*.1.*-
34
All hosts belonging to a domain with the address 100.172.1.13 will be allowed
access. All hosts belonging to domains starting with 100, then any number, then a
range of 30 to 54 will be allowed access. All hosts belonging to domains starting with
124, then from 24 onward, then 1, then from 0 to 34 will be allowed access.
◆ LSF_HOST_ADDR_RANGE=12.23.45.*
All hosts belonging to domains starting with 12.23.45 are allowed.
◆ LSF_HOST_ADDR_RANGE=100.*43
The * character can only be used to indicate any value. The format of this example
is not correct, and an error will be inserted in the LIM log and no hosts will be able
to join the cluster dynamically.
◆ LSF_HOST_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 able to join the cluster dynamically.
