    NetInfo

    
    
    

    DESCRIPTION

           There are two NetInfo files, one for an AFS client and one for an AFS
           File Server or database server.  The AFS client NetInfo file specifies
           the IP addresses that the client should register with the File Servers
           it connects to.  The server NetInfo file specifies what interfaces
           should be registered with AFS Database Servers or used to talk to other
           database servers.
    
       Client NetInfo
           The client NetInfo file lists the IP addresses of one or more of the
           local machine's network interfaces. If it exists in the /etc/openafs
           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 /etc/openafs/NetRestrict 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.
    
           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 NetInfo 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.
    
           To prohibit the Cache Manager absolutely from using one or more
           addresses, list them in the NetRestrict file. To display the addresses
           the Cache Manager is currently registering with File Servers, use the
           fs getclientaddrs command. To replace the current list of interfaces
           with a new one between reboots of the client machine, use the fs
           setclientaddrs command.
    
       Server NetInfo
           The server NetInfo file, if present in the /var/lib/openafs/local
           directory, defines the following:
    
           ?   On a file server machine, the local interfaces that the File Server
               (fileserver process) can register in the Volume Location Database
               (VLDB) at initialization time.
    
           ?   On a database server machine, the local interfaces that the Ubik
    
           The NetInfo file is in ASCII format. One of the machine's IP addresses
           appears on each line, in dotted decimal format. The order of the
           addresses is not significant.
    
           Optionally, the File Server can be forced to use an IP address that
           does not belong to one of the server interfaces. To do this, add a line
           to the NetInfo file with the IP address prefixed with "f" and a space.
           This is useful when the File Server is on the internal side of a NAT
           firewall.
    
           To display the File Server interface addresses registered in the VLDB,
           use the vos listaddrs command.
    
    
    

    EXAMPLES

           If the File Server is on the internal side of a NAT firewall, where it
           serves internal clients using the IP address 192.168.1.123 and external
           clients using the IP address 10.1.1.321, then the NetInfo file should
           contain the following:
    
              192.168.1.123
              f 10.1.1.321
