</PRE>
|
||
|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>fs setclientaddrs</B> 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.
|
||
|
|
<P>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.
|
||
|
|
<P>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 <B>/usr/vice/etc/NetInfo</B>
|
||
|
|
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 <B>/usr/vice/etc/NetRestrict</B>
|
||
|
|
file. It records the final list in kernel memory. (An
|
||
|
|
administrator must create the <B>NetInfo</B> and <B>NetRestrict</B>
|
||
|
|
files; there are no default versions of them.)
|
||
|
|
<P>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.
|
||
|
|
<P>To list the interfaces that the Cache Manager is currently registering with
|
||
|
|
File Servers, use the <B>fs getclientaddrs</B> command.
|
||
|
|
<P><STRONG>Cautions</STRONG>
|
||
|
|
<P>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 <B>/usr/vice/etc/NetInfo</B> file, or place
|
||
|
|
the appropriate <B>fs setclientaddrs</B> command in the machine's AFS
|
||
|
|
initialization script.
|
||
|
|
<P>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 <B>NetInfo</B> file and
|
||
|
|
reboot the client machine.
|
||
|
|
<P>The <B>fs</B> command interpreter verifies that each of the addresses
|
||
|
|
specified as a value for the <B>-address</B> 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
|
||
|
|
<TT>Nonexistent</TT> <TT>interface</TT>.
|
||
|
|
<P><STRONG>Options</STRONG>
