<P>Defines client machine interfaces to register with the File Server

|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>NetInfo</B> file lists the IP addresses of one or more of the
|
||
|
|
local machine's network interfaces. If it exists in the
|
||
|
|
<B>/usr/vice/etc</B> directory when the Cache Manager initializes, the
|
||
|
|
Cache Manager uses its contents as the basis for a list of local
|
||
|
|
interfaces. Otherwise, the Cache Manager uses the list of interfaces
|
||
|
|
configured with the operating system. It then removes from the list any
|
||
|
|
addresses that appear in the <B>/usr/vice/etc/NetRestrict</B> file, if it
|
||
|
|
exists. The Cache Manager records the resulting list in kernel
|
||
|
|
memory. The first time it establishes a connection to a File Server, it
|
||
|
|
registers the list with the File Server.
|
||
|
|
<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 <B>NetInfo</B> file is in ASCII format. One of the
|
||
|
|
machine's IP addresses appears on each line, in dotted decimal
|
||
|
|
format. The File Server initially uses the address that appears first
|
||
|
|
in the list. The order of the remaining addresses is not
|
||
|
|
significant: if an RPC to the first interface fails, the File Server
|
||
|
|
simultaneously sends RPCs to all of the other interfaces in the list.
|
||
|
|
Whichever interface replies first is the one to which the File Server then
|
||
|
|
sends pings and RPCs to break callbacks.
|
||
|
|
<P>To prohibit the Cache Manager absolutely from using one or more addresses,
|
||
|
|
list them in the <B>NetRestrict</B> file. To display the addresses
|
||
|
|
the Cache Manager is currently registering with File Servers, use the <B>fs
|
||
|
|
getclientaddrs</B> command. To replace the current list of interfaces
|
||
|
|
with a new one between reboots of the client machine, use the <B>fs
|
||
|
|
setclientaddrs</B> command.
