LSF Version 7.3 - Administering Platform LSF
Floating Client Licenses
178 Administering Platform LSF
FLOAT_CLIENTS_ADDR_RANGE parameter
This optional parameter specifies an IP address or range of addresses of domains
from which floating client hosts can submit requests. Multiple ranges can be
defined, separated by spaces. The IP address can have either a dotted quad notation
(IPv4) or IP Next Generation (IPv6) format. LSF supports both formats; you do not
have to map IPv4 addresses to an IPv6 format.
NOTE: You must uncomment FLOAT_CLIENTS_ADDR_RANGE (remove the # symbol before the
parameter) to have it take effect.
If the value of this parameter is undefined, there is no security and any host can be
an LSF floating client.
If a value is defined, security is enabled. When this parameter is defined, client hosts
that do not belong to the domain will be denied access. However, if there is an error
in the configuration of this variable, by default, no host will be allowed to be an LSF
floating client.
If a requesting host belongs to an IP address that falls in the specified range, the host
will be accepted to become an LSF floating client.
Address ranges are validated at configuration time so they must conform to the
required format. If any address range is not in the correct format, no host will be
accepted as an LSF floating client and a error message will be logged in the LIM log.
Conventions ◆ IP addresses are separated by spaces, and considered "OR" alternatives.
◆ The * character indicates any value is allowed.
◆ The - 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 2048 characters.
Examples FLOAT_CLIENTS_ADDR_RANGE=100
All IPv4 and IPv6 hosts with a domain address starting with 100 will be allowed
access.
◆ To specify only IPv4 hosts, set the value to 100.*
◆ To specify only IPv6 hosts, set the value to 100:*
FLOAT_CLIENTS_ADDR_RANGE=100-110.34.1-10.4-56
All client 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. No IPv6 hosts are allowed.
FLOAT_CLIENTS_ADDR_RANGE=100.172.1.13 100.*.30-54 124.24-*.1.*-34
