Overview
The bos exec command executes the indicated command on the file server machine named by the -server argument. Its intended use is to reboot the machine, using the /sbin/reboot command or equivalent.
Options
-server<machine name>-
Indicates the server machine on which to execute the command. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see bos(8).
-cmd<command to execute>-
Specifies the complete local disk pathname of the command to execute (for example, /sbin/reboot). Surround this argument with double quotes (
"") if the command contains one or more spaces.
-cell<cell name>-
Names the cell in which to run the command. Do not combine this argument with the
-localauthflag. For more details, see bos(8).
-
-noauth -
Assigns the unprivileged identity
"anonymous"to the issuer. Do not combine this flag with the-localauthflag. For more details, see bos(8).
-
-localauth -
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The
boscommand interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the-cellor-noauthoptions. For more details, see bos(8).
-
-help -
Prints the online help for this command. All other valid options are ignored.
Examples
The following command reboots the machine "fs2.example.com". The issuer has previously issued the bos shutdown command to shutdown all processes cleanly.
% bos exec -server fs2.example.com -cmd /sbin/shutdown -r nowPrivilege required
The issuer must be listed in the /etc/openafs/server/UserList file on the machine named by the -server argument, or must be logged onto a server machine as the local superuser "root" if the -localauth flag is included.
The bos exec command is not available on servers running in restricted mode.
