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 /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 /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 /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/log/openafs/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
