<P>Defines interfaces that File Server does not register in VLDB and Ubik does
|
|
not use for database server machines
|
|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>NetRestrict</B> file, if present in the
|
|
<B>/usr/afs/local</B> directory, defines the following:
|
|
<UL>
|
|
<P><LI>On a file server machine, the local interfaces that the File Server
|
|
(<B>fileserver</B> process) does not register in the Volume Location
|
|
Database (VLDB) at initialization time
|
|
<P><LI>On a database server machine, the local interfaces that the Ubik
|
|
synchronization library does not use when communicating with the database
|
|
server processes running on other database server machines
|
|
</UL>
|
|
<P>As it initializes, the File Server constructs a list of interfaces to
|
|
register, from the <B>/usr/afs/local/NetInfo</B> file if it exists, or
|
|
from the list of interfaces configured with the operating system
|
|
otherwise. The File Server then removes from the list any addresses
|
|
that appear in the <B>NetRestrict</B> file, if it exists. The File
|
|
Server records the resulting list in the <B>/usr/afs/local/sysid</B> file
|
|
and registers the interfaces in the VLDB. The database server processes
|
|
use a similar procedure when initializing, to determine which interfaces to
|
|
use for communication with the peer processes on other database machines in
|
|
the cell.
|
|
<P>The <B>NetRestrict</B> file is in ASCII format. One IP address
|
|
appears on each line, in dotted decimal format. The order of the
|
|
addresses is not significant. The value <B>255</B> is a wildcard
|
|
that represents all possible addresses in that field. For example, the
|
|
value <B>192.12.105.255</B> indicates that the Cache
|
|
Manager does not register any of the addresses in the
|
|
<B>192.12.105</B> subnet.
|
|
<P>To display the File Server interface addresses registered in the VLDB, use
|
|
the <B>vos listaddrs</B> command.
