    Command:

    upclient

    
    
    

    SYNOPSIS

           upclient <hostname> [-crypt] [-clear] [-t <retry time>]
               [-verbose]* <dir>+ [-help]
    
    
    

    DESCRIPTION

           The upclient command initializes the client portion of the Update
           Server. In the conventional configuration, its binary file is located
           in the /usr/lib/openafs directory on a file server machine.
    
           The upclient 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 upclient process periodically checks that all files in each local
           directory named by the dir argument match the files in the
           corresponding directory on the source machine named by the hostname
           argument. If a file does not match, the upclient process requests the
           source copy from the upserver process running on the source machine.
    
           By default, the upclient process requests that the upserver process
           encrypt the data before transferring it.  Use the -clear flag to
           request unencrypted transfer if appropriate. (The -crypt flag
           explicitly sets the default.)
    
           In the conventional configuration, separate instances of the upclient
           process request data from the /usr/lib/openafs and /etc/openafs/server
           directories, except on machines for which the system control machine is
           also the binary distribution machine for the machine's system type. The
           conventional names for the separate instances are "upclientbin" and
           "upclientetc" respectively.
    
           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 using the -clear option.  The contents of
           this directory are sensitive.
    
    
    

    OPTIONS

           <hostname>
               Names either the cell's system control machine (if the requested
               directory is /etc/openafs/server), or the binary distribution
               machine for the local machine's CPU and operating system type (if
               the requested directory is /usr/lib/openafs).
               amount of time it takes for a change made on the source machine to
               propagate to this machine.
    
           -verbose*
               Writes a trace of the upclient process's operations on the standard
               output stream, which usually corresponds to the machine console.
               Provide one, two, or three instances of the flag; each additional
               instance generates increasingly numerous and detailed messages.
    
           <dir>+
               Names each directory to check for modified files. The conventional
               choices are the following:
    
               ?   /usr/lib/openafs, in which case the recommended name for the
                   process (assigned with the -instance argument to the bos create
                   command) is "upclientbin". The hostname is the binary
                   distribution machine for the local machine's system type. You
                   may wish to use the -clear flag for the /usr/lib/openafs
                   directory, since binaries are not particularly sensitive and
                   encrypting them takes system resources.
    
               ?   /etc/openafs/server, in which case the recommended name for the
                   process (assigned with the -instance argument to the bos create
                   command) is "upclientetc". The hostname is the cell's system
                   control machine. Use the -crypt flag for the
                   /etc/openafs/server directory, since it contains the KeyFile
                   file and other data vital to cell security.
    
           -help
               Prints the online help for this command. All other valid options
               are ignored.
    
    
    

    EXAMPLES

           The following bos create command creates an "upclientbin" process on
           the machine "fs4.abc.com" that refers to the machine "fs1.abc.com" as
           the source for the /usr/lib/openafs directory (thus "fs1.abc.com" is
           the binary distribution machine for machines of "fs4.abc.com"'s type).
           The files in the /usr/lib/openafs directory are distributed every 120
           seconds.  The command requests transfer in unencrypted form.
    
              % bos create  -server fs4.abc.com -instance upclientbin -type simple \
                            -cmd "/usr/lib/openafs/upclient fs1.abc.com -clear \
                            -t 120 /usr/lib/openafs"
    
    
    

    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.
