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

PRIVILEGE REQUIRED

       The issuer must be logged in as the local superuser root.
