bos_uninstall - Reverts to the former version of a process's binary file
bos uninstall -server <machine name> -file <files to uninstall>+ [-dir <destination dir>] [-cell <cell name>] [-noauth] [-localauth] [-principal <authentication principal> [-encrypt [<yes|no>]] [-config <configuration file>] [-help]
The bos uninstall command replaces each binary file specified by the -file argument with its
.BAK version on the server machine named by the -server argument,
which is normally the binary distribution machine for its CPU/operating system type.
It also changes the extension on the current
.OLD version (if any) to
Each binary file must reside in the local /usr/libexec/yfs directory unless the -dir argument names an alternate directory.
To start using the reverted binary immediately, issue the bos restart command. Otherwise, the BOS Server automatically restarts the process at the time defined in the /etc/yfs/server/BosConfig file; use the bos getrestart command to display the time and the bos setrestart time to set it.
Indicates the binary distribution machine on which to revert to the
.BAK version of binaries.
Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously).
If the machine is not a binary distribution machine and is running an
then the files are overwritten the next time the
upclientbin process fetches the corresponding file from the distribution machine (by default within five minutes).
Names each binary file to replace with its
Provides the complete pathname of the local disk directory containing each file named by the -file argument. It is necessary only if the binaries are not in the /usr/libexec/yfs directory.
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
Assigns the unprivileged identity
anonymous to the issuer.
Do not combine this flag with the -localauth flag.
For more details,
Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt 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).
Indicates the principal to be used for authentication. This option can be useful when several credentials caches are available for different principals.
Enables or disables encryption for the command so that the operation's results are not transmitted across the network in clear text.
Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.
Prints the online help for this command. All other valid options are ignored.
The following example command overwrites the /usr/libexec/yfs/vlserver file on the machine
fs4.example.com with its
and the current
.BAK version by the
% bos uninstall -server fs4.example.com -file vlserver
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 uninstall command cannot be run against servers running in restricted mode.
