NAME

bos_exec - Executes a command on a remote server machine

SYNOPSIS

bos exec -server <machine name> -cmd <command to execute> [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-config <configuration file>] [-help]

DESCRIPTION

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 -localauth flag. For more details, see bos(8).

-noauth

Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see bos(8).

-localauth

Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileEx file. The bos command interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see bos(8).

-principal <authentication principal>

Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.

-encrypt [<yes|no>]

Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.

-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 now

PRIVILEGE REQUIRED

The issuer must be listed in the /etc/yfs/server/UserListExt file on the machine named by the -server argument, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included.

The bos exec command is not available on servers running in restricted mode.
