38 <P><STRONG>Description</STRONG>
39 <P>The <B>bos uninstall</B> command replaces each binary file specified by
40 the <B>-file</B> argument with its <TT>.BAK</TT>version on the
41 server machine named by the <B>-server</B> argument, which is normally the
42 binary distribution machine for its CPU/operating system type. It also
43 changes the extension on the current <TT>.OLD</TT> version (if any)
44 to <TT>.BAK</TT>. Each binary file must reside in the local
45 <B>/usr/afs/bin</B> directory unless the <B>-dir</B> argument names an
47 <P>To start using the reverted binary immediately, issue the <B>bos
48 restart</B> command. Otherwise, the BOS Server automatically restarts
49 the process at the time defined in the <B>/usr/afs/local/BosConfig</B>
50 file; use the <B>bos getrestart</B> command to display the time and
51 the <B>bos setrestart</B> time to set it.
52 <P><STRONG>Options</STRONG>
54 <P><DT><B><B>-server</B>
55 </B><DD>Indicates the binary distribution machine on which to revert to the
56 <TT>.BAK</TT> version of binaries. Identify the machine by IP
57 address or its host name (either fully-qualified or abbreviated
58 unambiguously). For details, see the introductory reference page for
59 the <B>bos</B> command suite.
60 <P>If the machine is not a binary distribution machine and is running an
61 <B>upclientbin</B> process, then the files are overwritten the next time
62 the <B>upclientbin</B> process fetches the corresponding file from the
63 distribution machine (by default within five minutes).
64 <P><DT><B><B>-file</B>
65 </B><DD>Names each binary file to replace with its <TT>.BAK</TT>
68 </B><DD>Provides the complete pathname of the local disk directory containing each
69 file named by the <B>-file</B> argument. It is necessary only if
70 the binaries are not in the <B>/usr/afs/bin</B> directory.
71 <P><DT><B><B>-cell</B>
72 </B><DD>Names the cell in which to run the command. Do not combine this
73 argument with the <B>-localauth</B> flag. For more details, see the
74 introductory <B>bos</B> reference page.
75 <P><DT><B><B>-noauth</B>
76 </B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
77 issuer. Do not combine this flag with the <B>-localauth</B>
78 flag. For more details, see the introductory <B>bos</B> reference
80 <P><DT><B><B>-localauth</B>
81 </B><DD>Constructs a server ticket using a key from the local
82 <B>/usr/afs/etc/KeyFile</B> file. The <B>bos</B> command
83 interpreter presents the ticket to the BOS Server during mutual
84 authentication. Do not combine this flag with the <B>-cell</B> or
85 <B>-noauth</B> options. For more details, see the introductory
86 <B>bos</B> reference page.
88 </B><DD>Prints the online help for this command. All other valid options
91 <P><STRONG>Examples</STRONG>
92 <P>The following example command overwrites the
93 <B>/usr/afs/bin/kaserver</B> file on the machine
94 <B>fs4.abc.com</B> with its <TT>.BAK</TT>version,
95 and the current <TT>.BAK</TT> version by the
97 <PRE> % <B>bos uninstall -server fs4.abc.com -file kaserver</B>
100 <P><STRONG>Privilege Required</STRONG>
101 <P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
102 the machine named by the <B>-server</B> argument, or must be logged onto a
103 server machine as the local superuser <B>root</B> if the
104 <B>-localauth</B> flag is included.
