VOS_CHANGEADDR(1)					       AFS Command Reference						 VOS_CHANGEADDR(1)

NAME

       vos_changeaddr - Changes or removes a file server machine's entry in the VLDB

SYNOPSIS

       vos changeaddr -oldaddr <original IP address>
	   [-newaddr <new IP address>] [-remove]
	   [-cell <cell name>] [-noauth] [-localauth]
	   [-verbose] [-encrypt] [-noresolve] [-help]

       vos changea -o <original IP address>
	   [-ne <new IP address>] [-r]
	   [-c <cell name>]
	   [-noa] [-l] [-v] [-e] [-nor] [-h]

DESCRIPTION

       The vos changeaddr command removes a server entry from the Volume Location Database (VLDB) when the -remove flag is combined with the
       -oldaddr argument. There must be no VLDB entries that list the machine as a site for any version of a volume (if necessary, use the vos
       move or vos remove command to more or remove volumes). It is appropriate to remove a VLDB server entry when removing the corresponding file
       server machine from service; this is the only recommended use of the command.

       To display all VLDB server entries, use the vos listaddrs command.

CAUTIONS

       Combining the command's -oldaddr and -newaddr arguments is no longer the appropriate way to change the IP address registered for a file
       server machine. Furthermore, if a machine is multihomed and its server entry includes several addresses, then the address specified with
       the -newaddr argument replaces all of the addresses currently listed in the server entry that includes the address specified by the
       -oldaddr argument. This effectively makes the machine single-homed with respect to AFS operations, which is probably not the desired
       result.

       The recommended method for changing the IP addresses in a server entry is instead to restart the "fs" process group (which includes the
       File Server) after using the utilities provided by the operating system to reconfigure the machine's network interfaces. For a description
       of how the File Server constructs and registers a list of its network interfaces in the VLDB, see sysid(5).

       If, counter to recommended usage, the command is used to change the IP address in a server entry, it does not also change the names of
       machine entries in the Protection Database. Operations fail when they refer to a protection group that has an obsolete IP address in it.
       Use the pts rename command to change the names of machine entries that correspond to the addresses changed with this command. Changing the
       address of a database server machine also requires updating the client and server versions of the CellServDB file on every machine.

OPTIONS

       -oldaddr <original IP address>
	   Specifies the IP address currently registered for the file server machine in the VLDB server entry. If there are multiple addresses
	   registered for a multihomed machine, use any of them to identify the server entry.

       -newaddr <new IP address>
	   Specifies the new IP address that replaces all currently registered addresses.

       -remove
	   Removes from the VLDB the server entry that includes the address specified by the -oldaddr argument.

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see vos(1).

       -noauth
	   Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see
	   vos(1).

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The vos command interpreter presents it to the
	   Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the -cell argument or -noauth
	   flag. For more details, see vos(1).

       -verbose
	   Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and
	   error messages appear.

       -encrypt
	   Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in
	   OpenAFS versions 1.4.11 or later and 1.5.60 or later.

       -noresolve
	   Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as 127.0.0.1 or
	   when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later.

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following command removes the VLDB server entry that includes the IP address 192.12.107.214.

	  % vos changeaddr -oldaddr 192.12.107.214 -remove

PRIVILEGE REQUIRED

       Issuer must be listed in the /etc/openafs/server/UserList file on the machine specified with the -oldaddr argument and on each database
       server machine.
