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] [-help]

bos u -s <machine name> -f <files to uninstall>+
[-d <destination dir>] [-c <cell name>] [-n] [-l]


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 .BAK. Each binary file must reside in the local /usr/local/libexec/openafs 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 /usr/local/etc/openafs/BosConfig file; use the bos getrestart command to display the time and the bos setrestart time to set it.


-server <machine name> 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). For details, see bos(8).

If the machine is not a binary distribution machine and is running an upclientbin process, then the files are overwritten the next time the upclientbin process fetches the corresponding file from the distribution machine (by default within five minutes).

-file <files to uninstall>+ Names each binary file to replace with its .BAK version.
-dir <destinatino dir> 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/local/libexec/openafs directory.
-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 /usr/local/etc/openafs/server/KeyFile 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).
-help Prints the online help for this command. All other valid options are ignored.


The following example command overwrites the /usr/local/libexec/openafs/kaserver file on the machine with its .BAK version, and the current .BAK version by the .OLD version.

   % bos uninstall -server -file kaserver


The issuer must be listed in the /usr/local/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 uninstall command cannot be run against servers running in restricted mode.
