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.
