LSF Version 7.3 - Platform LSF Configuration Reference

LSF Floating Client
Although an LSF Floating Client requires a license, LSF_Float_Client does not need to be
added to the PRODUCTS line. LSF_Float_Client also cannot be added as a resource for specific
hosts already defined in lsf.cluster.cluster_name. Should these lines be present, they are
ignored by LSF.
Default
Undefined
FLOAT_CLIENTS_ADDR_RANGE
Syntax
FLOAT_CLIENTS_ADDR_RANGE=IP_address ...
Description
Optional. 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:
To use IPv6 addresses, you must define the parameter
LSF_ENABLE_SUPPORT_IPV6 in lsf.conf.
If the value of FLOAT_CLIENT_ADDR_RANGE is undefined, there is no security and any
hosts can be LSF floating clients.
If a value is defined, security is enabled. If there is an error in the configuration of this variable,
by default, no hosts will be allowed to be LSF floating clients.
When this parameter is defined, client hosts that do not belong to the domain will be denied
access.
If a requesting host belongs to an IP address that falls in the specified range, the host will be
accepted to become a floating client.
IP addresses are separated by spaces, and considered "OR" alternatives.
If you define FLOAT_CLIENT_ADDR_RANGE with:
•
No range specified, all IPv4 and IPv6 clients can submit requests.
•
Only an IPv4 range specified, only IPv4 clients within the range can submit requests.
•
Only an IPv6 range specified, only IPv6 clients within the range can submit requests.
•
Both an IPv6 and IPv4 range specified, IPv6 and IPv4 clients within the ranges can submit
requests.
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.
