19 | =head1 DESCRIPTION | |
20 | ||
21 | The B<bos addhost> command adds an entry for each database server machine | |
22 | specified with the B<-host> argument to the F</usr/afs/etc/CellServDB> | |
23 | file on the machine named by the B<-server> argument. | |
24 | ||
25 | =head1 CAUTIONS | |
26 | ||
27 | After executing this command (and waiting for the Update Server to | |
28 | propagate the changes, if it is used), restart the database server | |
29 | processes on all database server machines to force election of a quorum | |
30 | that includes the new set of machines listed in the | |
31 | F</usr/afs/etc/CellServDB> file. The I<OpenAFS Quick Start Guide> explains | |
32 | in more detail how to add and remove database server machines. | |
33 | ||
34 | It is best to maintain a one-to-one mapping between hostnames and IP | |
35 | addresses on a multihomed database server machine (this is actually the | |
36 | conventional configuration for any AFS machine). The BOS Server uses the | |
37 | gethostbyname() routine to obtain the IP address associated with the | |
38 | hostname specified by the B<-host> argument. If there is more than one | |
39 | address, the BOS Server records in the F<CellServDB> entry the one that | |
40 | appears first in the list of addresses returned by the routine. The | |
41 | routine possibly returns addresses in a different order on different | |
42 | machines, which can create inconsistency. | |
43 | ||
44 | =head1 OPTIONS | |
45 | ||
46 | =over 4 | |
47 | ||
48 | =item B<-server> <I<machine name>> | |
49 | ||
50 | Identifies the server machine on which to change the | |
51 | F</usr/afs/etc/CellServDB> file. Identify the machine by IP address or its | |
52 | host name (either fully-qualified or abbreviated unambiguously). For | |
53 | details, see L<bos(8)>. | |
54 | ||
55 | In cells that use the Update Server to distribute the contents of the | |
56 | F</usr/afs/etc> directory, it is conventional to specify only the system | |
57 | control machine as a value for the B<-server> argument. Otherwise, repeat | |
58 | the command for each file server machine. For further discussion, see | |
59 | L<bos(8)>. | |
60 | ||
61 | =item B<-host> <I<host name>>+ | |
62 | ||
63 | Specifies the fully-qualified host name (such as C<db1.example.com>) of each | |
64 | database server machine to register in the F<CellServDB> file. | |
65 | ||
66 | =item B<-cell> <I<cell name>> | |
67 | ||
68 | Names the cell in which to run the command. Do not combine this | |
69 | argument with the B<-localauth> flag. For more details, see L<bos(8)>. | |
70 | ||
71 | =item B<-clone> | |
72 | ||
73 | Register the host given by B<-host> as a non-voting clone site, which | |
74 | prevents the host from becoming a sync-site. This is an advanced feature | |
75 | and should be used with caution. | |
76 | ||
77 | =item B<-noauth> | |
78 | ||
79 | Assigns the unprivileged identity C<anonymous> to the issuer. Do not combine | |
80 | this flag with the B<-localauth> flag. For more details, see L<bos(8)>. | |
81 | ||
82 | =item B<-localauth> | |
83 | ||
84 | Constructs a server ticket using a key from the local | |
85 | F</usr/afs/etc/KeyFile> or F</usr/afs/etc/KeyFileExt> file. | |
86 | The B<bos> command interpreter presents the | |
87 | ticket to the BOS Server during mutual authentication. Do not combine this | |
88 | flag with the B<-cell> or B<-noauth> options. For more details, see | |
89 | L<bos(8)>. | |
90 | ||
91 | =item B<-help> | |
92 | ||
93 | Prints the online help for this command. All other valid options are | |
94 | ignored. | |
95 | ||
96 | =back | |
97 | ||
98 | =head1 EXAMPLES | |
99 | ||
100 | The following command adds the database server machines C<db2.example.com> and | |
101 | C<db3.example.com> to the F</usr/afs/etc/CellServDB> file on the machine | |
102 | C<fs1.example.com> (the system control machine). | |
103 | ||
104 | % bos addhost -server fs1.example.com -host db2.example.com db3.example.com | |
105 | ||
106 | =head1 PRIVILEGE REQUIRED | |
107 | ||
108 | The issuer must be listed in the F</usr/afs/etc/UserList> file on the | |
109 | machine named by the B<-server> argument, or must be logged onto a server | |
110 | machine as the local superuser C<root> if the B<-localauth> flag is | |
111 | included. | |
