# bos\_start(8)

Starts a process after setting its status flag

## NAME

bos\_start - Starts a process after setting its status flag

## SYNOPSIS

**bos start** **-server** \<*machine name*\>\
     **-instance** \<*server process name*\>+ \[**-cell** \<*cell name*\>\]\
     \[**-noauth**\] \[**-localauth**\] \[**-help**\]

**bos start** **-s** \<*machine name*\> **-i** \<*server process name*\>+\
     \[**-c** \<*cell name*\>\] \[**-n**\] \[**-l**\] \[**-h**\]

## DESCRIPTION

The **bos start** command sets the status flag for each process specified by the **-instance** argument to `"Run"` in the */etc/openafs/BosConfig* file and in the BOS Server's memory on the server machine named by the **-server** argument, then starts it. If the process is already running, the command's only effect is to guarantee that the status flag is `"Run"`; it does not restart the process.

To start a process without changing its status flag in the *BosConfig* file, use the **bos startup** command instead.

## OPTIONS

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

  Indicates the server machine on which to start processes. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see [**bos**(8)](/bos/8.md).

- **-instance** \<*server process name*\>+

  Names each process to start. Use the process name assigned with the **-instance** argument to the **bos create** command. The output from the **bos status** command lists the names.

- **-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.

## EXAMPLES

The following command changes the status flag for the `"upclientbin"` and `"upclientetc"` processes to `"Run"` in the *BosConfig* file on the machine `"fs6.example.com"` and starts them running.

```
   % bos start -server fs6.example.com -instance upclientbin upclientetc
```

## PRIVILEGE REQUIRED

The issuer must be listed in the */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.
