NAME

       upserver - Initializes the server portion of the Update Server

SYNOPSIS

       upserver [<directory>+] [-crypt <directory>+]
           [-clear <directory>+] [-auth <directory>+] [-help]

DESCRIPTION

       The upserver command initializes the server portion of the Update
       Server (the "upserver" process). In the conventional configuration, its
       binary file is located in the /usr/lib/openafs directory on a file
       server machine.

       The upserver command is not normally issued at the command shell prompt
       but rather placed into a file server machine’s /etc/openafs/BosConfig
       file with the bos create command. If it is ever issued at the command
       shell prompt, the issuer must be logged onto a database server machine
       as the local superuser "root".

       The upserver command specifies which of the directories on the local
       disk are eligible for distribution in response to requests from the
       client portion of the Update Server (the upclient process) running on
       other machines. If no directories are specified, the upserver process
       distributes the contents of any directory on its local disk.

       The upserver process can distribute a directory’s contents in encrypted
       or unencrypted form. By default, it does not use encryption unless an
       upclient process requests it (this default is equivalent to setting the
       -clear flag). When the -crypt flag is provided, the upserver process
       only fulfills requests for encrypted transfer.

       The upclient and upserver processes always mutually authenticate,
       whether or not the data they pass is encrypted; they use the key with
       the highest key version number in the /etc/openafs/server/KeyFile file
       to construct a server ticket for mutual authentication.

       This command does not use the syntax conventions of the AFS command
       suites. Provide the command name and all option names in full.

CAUTIONS

       Do not use the Update Server to distribute the contents of the
       /etc/openafs/server directory without the -crypt flag.  The contents of
       this directory are sensitive.

OPTIONS

       <directory>+
           Names each directory to distribute in unencrypted form (because
           they appear before the first -crypt or -clear flag on the command
           line). If this argument is omitted, all directories on the
           machine’s local disk are eligible for distribution.

       -crypt <directory>+
           Precedes a list of one or more directories that the upserver
           process distributes only in encrypted form.

       -clear <directory>+
           Precedes a list of one or more directories that the upserver
           process distributes in unencrypted form unless the upclient process
           requests them in encrypted form. Use this argument only if a list
           of directories headed by the -crypt flag precedes it on the command
           line.

       -auth <directory>+
           Precedes a list of one or more directories which the upserver
           process distributes using a form of encryption that is intermediate
           in complexity and security between the unencrypted and encrypted
           levels set by the -clear and -crypt arguments. Do not use this
           argument, because the upclient process does not have a
           corresponding argument that it can use to request data transfer at
           this level.

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

EXAMPLES

       The following example bos create command defines and starts an upserver
       process on the host machine "fs1.abc.com". The last parameter (enclosed
       in quotes) instructs the upserver process to distribute the contents of
       the /usr/lib/openafs directory in unencrypted form and the contents of
       the /etc/openafs/server directory in encrypted form.

          % bos create  -server fs1.abc.com -instance upserver -type simple \
              -cmd "/usr/lib/openafs/upserver /usr/lib/openafs -crypt /etc/openafs/server"

PRIVILEGE REQUIRED

       The issuer must be logged in as the superuser "root" on a file server
       machine to issue the command at a command shell prompt. It is
       conventional instead to create and start the process by issuing the bos
       create command.
