    Command:

    fs_setcell

    
    
    
    

    SYNOPSIS

           fs setcell -cell <cell name>+ [-suid] [-nosuid] [-help]
    
           fs setce -c <cell name>+ [-s] [-n] [-h]
    
    
    

    DESCRIPTION

           The fs setcell command sets whether the Cache Manager allows programs
           (and other executable files) from each cell named by the -cell argument
           to run with setuid permission. By default, the Cache Manager allows
           programs from its home cell to run with setuid permission, but not
           programs from any foreign cells. A program belongs to the same cell as
           the file server machine that houses the volume in which the program's
           binary file resides, as specified in the file server machine's
           /etc/openafs/server/ThisCell file. The Cache Manager determines its own
           home cell by reading the /etc/openafs/ThisCell file at initialization.
    
           To enable programs from each specified cell to run with setuid
           permission, include the -suid flag. To prohibit programs from running
           with setuid permission, include the -nosuid flag, or omit both flags.
    
           The fs setcell command directly alters a cell's setuid status as
           recorded in kernel memory, so rebooting the machine is unnecessary.
           However, non-default settings do not persist across reboots of the
           machine unless the appropriate fs setcell command appears in the
           machine's AFS initialization file.
    
           To display a cell's setuid status, issue the fs getcellstatus command.
    
    
    

    CAUTIONS

           AFS does not recognize effective UID: if a setuid program accesses AFS
           files and directories, it does so using the current AFS identity of the
           AFS user who initialized the program, not of the program's owner.  Only
           the local file system recognizes effective UID.
    
           Only members of the system:administrators group can turn on the setuid
           mode bit on an AFS file or directory.
    
           When the setuid mode bit is turned on, the UNIX "ls -l" command
           displays the third user mode bit as an "s" instead of an "x". However,
           the "s" does not appear on an AFS file or directory unless setuid
           permission is enabled for the cell in which the file resides.
    
    
    

    OPTIONS

           -cell <cell name>+
               Names each cell for which to set setuid status. Provide the fully
               qualified domain name, or a shortened form that disambiguates it
               from the other cells listed in the local /etc/openafs/CellServDB
               file.
    
           -suid
               Allows programs from each specified cell to run with setuid
    
           University cell to run with setuid privilege on the local machine:
    
              % fs setcell -cell stateu.edu -suid
    
    
    

    PRIVILEGE REQUIRED

           The issuer must be logged in as the local superuser root.
