# bos\_listhosts(8)

Displays the contents of the CellServDB file

## NAME

bos\_listhosts - Displays the contents of the CellServDB file

## SYNOPSIS

**bos listhosts** **-server** \<*machine name*\> \[**-cell** \<*cell name*\>\]\
     \[**-noauth**\] \[**-localauth**\] \[**-help**\]

**bos listh** **-s** \<*machine name*\> \[**-c** \<*cell name*\>\] \[**-n**\]\
     \[**-l**\]  \[-h\]

**bos getcell** **-server** \<*machine name*\> \[**-cell** \<*cell name*\>\]\
     \[**-noauth**\] \[**-localauth**\] \[**-help**\]

**bos getc** **-s** \<*machine name*\> \[**-c** \<*cell name*\>\] \[**-n**\]\
     \[**-l**\] \[-h\]

## DESCRIPTION

The **bos listhosts** command formats and displays the list of a cell's database server machines from the */etc/openafs/server/CellServDB* file on the server machine named by the **-server** argument.

To alter the list of machines, use the **bos addhost** and **bos** **removehost** commands.

## OPTIONS

- **-server** \<*machine name*\>

  Indicates the server machine from which to display the */etc/openafs/server/CellServDB* file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see [**bos**(8)](/bos/8.md).

  For consistent performance in the cell, the output must be the same on every server machine. The **bos addhost** reference page explains how to keep the machines synchronized.

- **-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)](/bos/8.md).

- **-noauth**

  Assigns the unprivileged identity `"anonymous"` to the issuer. Do not combine this flag with the **-localauth** flag. For more details, see [**bos**(8)](/bos/8.md).

- **-localauth**

  Constructs a server ticket using a key from the local */etc/openafs/server/KeyFile* or */etc/openafs/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)](/bos/8.md).

- **-help**

  Prints the online help for this command. All other valid options are ignored.

## OUTPUT

The first line of the output names the cell to which the server machine belongs. Each of the following lines names a database server machine for that cell.

The `"Host"` number assigned to each database server machine is for server-internal use only and is not the same as, nor necessarily related to, the machine's IP address. The BOS Server assigned it as part of performing the **bos addhost** command.

## EXAMPLES

The following command displays the database server machines listed in the */etc/openafs/server/CellServDB* file on the machine `"fs7.example.com"`.

```
   % bos listhosts fs7.example.com
   Cell name is example.com
       Host 1 is db1.example.com
       Host 2 is db2.example.com
       Host 3 is db3.example.com
```

## PRIVILEGE REQUIRED

None
