FS_SETCLIENTADDRS(1)	     AFS Command Reference	  FS_SETCLIENTADDRS(1)

NAME
       fs_setclientaddrs - Sets	the client interfaces to register with the
       File Server

SYNOPSIS
       fs setclientaddrs [-address <client network interfaces>+] [-help]

       fs setcl	[-a <client network interfaces>+] [-h]

       fs sc [-a <client network interfaces>+] [-h]

DESCRIPTION
       The fs setclientaddrs command defines the IP addresses of the
       interfaces that the local Cache Manager registers with a	File Server
       when first establishing a connection to it.

       The File	Server uses the	addresses when it initiates a remote procedure
       call (RPC) to the Cache Manager (as opposed to responding to an RPC
       sent by the Cache Manager). There are two common	circumstances in which
       the File	Server initiates RPCs: when it breaks callbacks	and when it
       pings the client	machine	to verify that the Cache Manager is still
       accessible.

       The list	of interfaces specified	with this command replaces the list
       that the	Cache Manager constructs and records in	kernel memory as it
       initializes. At that time, if the file /usr/local/etc/openafs/NetInfo
       exists on the client machine's local disk, the Cache Manager uses its
       contents	as the basis for the list of interfaces	addresses. If the file
       does not	exist, the Cache Manager instead uses the network interfaces
       configured with the operating system. It	then removes from the list any
       address included	in the local /usr/local/etc/openafs/NetRestrict	file.
       It records the final list in kernel memory. (An administrator must
       create the NetInfo and NetRestrict files; there are no default versions
       of them.)

       If an RPC to that interface fails, the File Server simultaneously sends
       RPCs to all of the other	interfaces in the list,	to learn which of them
       are still available. Whichever interface	replies	first is the one to
       which the File Server then sends	pings and RPCs to break	callbacks.

       To list the interfaces that the Cache Manager is	currently registering
       with File Servers, use the fs getclientaddrs command.

CAUTIONS
       The list	specified with this command persists in	kernel memory only
       until the client	machine	reboots. To preserve it	across reboots,	either
       list the	interfaces in the local	/usr/local/etc/openafs/NetInfo file,
       or place	the appropriate	fs setclientaddrs command in the machine's AFS
       initialization script.

       Changes made with this command do not propagate automatically to	File
       Servers to which	the Cache Manager has already established a
       connection. To force such File Servers to use the revised list, either
       reboot each file	server machine,	or change the NetInfo file and reboot
       the client machine.

       The fs command interpreter verifies that	each of	the addresses
       specified as a value for	the -address argument is actually configured
       with the	operating system on the	client machine.	If it is not, the
       command fails with an error message that	marks the address as a
       "Nonexistent interface".

OPTIONS
       -address	<client	network	interfaces>+
	   Specifies each IP address to	place in the list of interfaces, in
	   dotted decimal format. Hostnames are	not acceptable.	Separate each
	   address with	one or more spaces.

       -help
	   Prints the online help for this command. All	other valid options
	   are ignored.

OUTPUT
       The message

	  Adding <interface>

       confirms	that each new interface	was added to the Cache Manager's list.
       The address appears in hexadecimal format to match the notation used in
       the File	Server log, /var/openafs/logs/FileLog.

EXAMPLES
       The following example sets the two interfaces that the Cache Manager
       registers with File Servers.

	  % fs setclientaddrs 191.255.105.68 191.255.108.84
	  Adding 0xbfff6944
	  Adding 0xbfff6c54
