19 | =head1 DESCRIPTION | |
20 | ||
21 | The B<bos removehost> command removes the entry for each database server | |
22 | machine specified with the B<-host> argument from the | |
23 | F</usr/afs/etc/CellServDB> file on the server machine named by the | |
24 | B<-server> argument. | |
25 | ||
26 | =head1 CAUTIONS | |
27 | ||
28 | After executing this command (and waiting for the Update Server to | |
29 | propagate the changes, if it is used), restart the database server | |
30 | processes on all database server machines to force election of a quorum | |
31 | that includes the new set of machines listed in the | |
32 | F</usr/afs/etc/CellServDB> file. The I<OpenAFS Quick Start Guide> explains | |
33 | in more detail how to add and remove database server machines. | |
34 | ||
35 | =head1 OPTIONS | |
36 | ||
37 | =over 4 | |
38 | ||
39 | =item B<-server> <I<machine name>> | |
40 | ||
41 | Indicates the server machine on which to change the | |
42 | F</usr/afs/etc/CellServDB> file. Identify the machine by IP address or its | |
43 | host name (either fully-qualified or abbreviated unambiguously). For | |
44 | details, see L<bos(8)>. | |
45 | ||
46 | In cells that use the Update Server to distribute the contents of the | |
47 | F</usr/afs/etc> directory, it is conventional to specify only the system | |
48 | control machine as a value for the B<-server> argument. Otherwise, repeat | |
49 | the command for each file server machine. For further discussion, see | |
50 | L<bos(8)>. | |
51 | ||
52 | =item B<-host> <I<host name>>+ | |
53 | ||
54 | Specifies the fully-qualified host name (such as C<fs2.example.com>) of each | |
55 | database server machine to remove from the B<CellServDB> file. | |
56 | ||
57 | =item B<-cell> <I<cell name>> | |
58 | ||
59 | Names the cell in which to run the command. Do not combine this argument | |
60 | with the B<-localauth> flag. For more details, see L<bos(8)>. | |
61 | ||
62 | =item B<-noauth> | |
63 | ||
64 | Assigns the unprivileged identity C<anonymous> to the issuer. Do not | |
65 | combine this flag with the B<-localauth> flag. For more details, see | |
66 | L<bos(8)>. | |
67 | ||
68 | =item B<-localauth> | |
69 | ||
70 | Constructs a server ticket using a key from the local | |
71 | F</usr/afs/etc/KeyFile> or F</usr/afs/etc/KeyFileExt> file. | |
72 | The B<bos> command interpreter presents the | |
73 | ticket to the BOS Server during mutual authentication. Do not combine this | |
74 | flag with the B<-cell> or B<-noauth> options. For more details, see | |
75 | L<bos(8)>. | |
76 | ||
77 | =item B<-help> | |
78 | ||
79 | Prints the online help for this command. All other valid options are | |
80 | ignored. | |
81 | ||

83 | ||
84 | =head1 EXAMPLES | |
85 | ||
86 | The following command removes the former database server machine | |
87 | C<db2.example.com> from the F<CellServDB> file on the system control machine | |
88 | C<fs1.example.com>. | |
89 | ||
90 | % bos removehost -server fs1.example.com -host db2.example.com | |
91 | ||
92 | =head1 PRIVILEGE REQUIRED | |
93 | ||
94 | The issuer must be listed in the F</usr/afs/etc/UserList> file on the | |
95 | machine named by the B<-server> argument, or must be logged onto a server | |
96 | machine as the local superuser C<root> if the B<-localauth> flag is | |
97 | included. | |
