Ubuntu Manpage: sfcbd - Small-Footprint CIM Broker (sfcb)

NAME

       sfcbd - Small-Footprint CIM Broker (sfcb)

SYNOPSIS

       sfcbd [options]

DESCRIPTION

       sfcb  is  a lightweight CIM daemon (aka CIMOM) that responds to CIM client requests for system management
       data and/or performs system management tasks. sfcb supports most of the standard CIM XML over  http/https
       protocol.   It  is  highly  modular, allowing functionality to be easily added, removed or customized for
       different management applications. sfcb is specifically targetted for small embedded system that  do  not
       have  the  available  CPU, memory or disk resources to support a full-blown enterprise-level CIMOM.  That
       said, sfcb runs very well on a regular Linux/Unix system and supports most of the functions  required  by
       CIM clients to manage such the system.  Supported CIM operations include:

              GetClass
              EnumerateClasses
              EnumerateClassNames
              GetInstance
              DeleteInstance
              CreateInstance
              ModifyInstance
              EnumerateInstances
              EnumerateInstanceNames
              InvokeMethod (MethodCall)
              ExecQuery
              Associators
              AssociatorNames
              References
              ReferenceNames

       CIM process and lifecycle indications (aka 'events') are also supported.

OPTIONS

       Supported command line options are:

       -c, --config-file=FILE
              Specify an alternative configuration file.  Default=/etc/sfcb/sfcb.cfg

       -d, --daemon
              Run sfcbd (and child processes) in the background.

       -h, --help
              Print help message and exit.

       -k, --color-trace
              -k, --color-trace Color the trace output of each process

       -s, --collect-stats
              Turn  on  runtime  statistics collecting. If enabled then various sfcbd runtime statistics will be
              written to ./sfcbStat.  Default is no statistics are collected.

       -t, --trace-components=NUM
              Activate component-level tracing messages, where NUM is an OR-ed bitmask  integer  defining  which
              component  to  trace.  Specifying "-t ?" will list all the components and their associated integer
              bitmask.

       -v, --version
              Prints version information and exits.

CONFIGURATION FILE

sfcbd reads the configuration file /etc/sfcb/sfcb.cfg (or the file specified with the -c option) at start
up. The configuration file contains option : value pairs, one per line. For a complete list of options,
see the default configuration file included with the sfcb package.

httpPort
Local port that sfcbd should listen to receive HTTP (i.e. insecure) requests from CIM clients.
Default=5988

enableHttp
Whether sfcb should accept HTTP client connections. Default=true.

httpProcs
Maximum number of simultaneous HTTP client connections before blocking new incoming HTTP requests.
Default=8

httpsPort
Local port that sfcbd should listen to receive HTTPS (i.e. secure) requests from CIM clients.
Default=5989

enableHttps
Whether sfcb should accept HTTPS client connections. Default=false.

httpsProcs
Maximum number of simultaneous HTTPS client connections before blocking new incoming HTTPS
requests. Default=8

enableInterOp
Whether sfcb should provide the interop namespace for indication support. Default=true

provProcs
Maximum number of simultaneous provider processes. After this point if a new incoming request
requires loading a new provider, then one of the existing providers will first be automatically
unloaded. Default=32

doBasicAuth
Perform basic authentication on the client userid (obtained from the HTTP/HTTPS header) before
allowing the request. Default=false (i.e. no client authentication performed).

basicAuthLib
Name of the local library to call to authenticate the client userid.
Default=sfcBasicAuthentication

useChunking
Tell sfcbd to use HTTP/HTTPS 'chunking' to return large volumes of response data to the client in
'chunks', rather than buffering the data and sending it back all at once. Default=true

keepaliveTimeout
Specify the maximum time in seconds an sfcb HTTP process will wait between two requests on one
connection before terminating. Setting it to 0 will disable HTTP keep-alive. Default=0

keepaliveMaxRequest
Specify the maximum number of consecutive request on one connection. Setting it to 0 will
effectively disable HTTP keep-alive. Default=10

registrationDir
Specify the registration directory, which contains the provider registration data, the staging
area and the static repository. Default=/var/lib/sfcb/registration

providerDirs
A space separated list of directories where sfcb is looking for provider libraries.
Default=/usr/lib /usr/lib/cmpi

providerSampleInterval
The interval in seconds at which the provider manager is checking for idle providers. Default: 30

providerTimeoutInterval
The interval in seconds before an idle provider gets unloaded by the provider manager. Default: 60

providerAutoGroup
If set to true, all providers residing in the same shared library will be executed in the same
process unless another group has been specified in the provider registration file. Default: true

sslCertificateFilePath
Specify the name of the file containing the server's certificate. The file must be in PEM format.
This file is only required if enableHttps is set to true. Default= /etc/sfcb/server.pem

sslKeyFilePath
Specify the name of the file containing the private key for the server's certificate. The file
must be in PEM format and may not be passphrase-protected. This file is only required if
enableHttps is set to true. Default=/etc/sfcb/file.pem

sslClientTrustStore
Specify the name of the file or directory containing either the CA certificate issuing client
certificates or self-signed certificates of the clients. This setting is only required if
sslClientCertificate is set to accept or require.

If a file, it must be in PEM format.

If a directory, it must be in "hash format": each file in the directory should be named hash.0,
where hash is the output of openssl x509 -hash. See the -CApath option in verify(1) from the
openssl package for more information about the hash format.

Default=/etc/sfcb/client.pem

sslClientCertificate
Specify the way sfcb handles client certificate based authentication. If set to ignore it will not
request a certificate from the client. If set to accept it will request a certificate from the
client but not fail if the client doesn't present one. If set to require it will refuse the client
connection if the client doesn't present a certificate. Default=ignore

certificateAuthLib
Name of the local library to call for client-certificate based user authentication. Called only if
sslClientCertificate is not set to ignore. Default=sfcCertificateAuthentication

traceLevel
Specify the trace level for sfcb. Can be overriden by setting environment variable
SFCB_TRACE_LEVEL. Default:0.

traceMask
Specify the trace mask for sfcb. Can be overriden by the command line option --trace-components.
Default: 0.

traceFile
Specify the trace file for sfcb. Can be overriden by setting environment variable SFCB_TRACE_FILE.
Default: stderr.

ENVIRONMENT

SFCB_PAUSE_PROVIDER
Specifies the name of the provider to pause after first being loaded to facilitate attaching a
runtime debugger to the provider's process for debugging purposes.

SFCB_PAUSE_CODEC
Specifies the name of the sfcb codec (currently only "http") to pause after first being started to
facilitate attaching a runtime debugger to the process.

SFCB_TRACE
Specifies the level of trace/debug messages for sfcb. Valid values are 0 (no trace messages), or
1 (key trace messages only) to 4 (all messages). A default value of 1 will be assumed, if this
variable is not set.
[Note: SFCB_TRACE level is used in conjunction with sfcb's component-level tracing to control the
level of detail of trace messages to display within each component]

SFCB_TRACE_FILE
By default sfcb trace messages are written to STDERR. Setting this envorinment variable causes
the trace messages to be written to a file instead.

SFCB_TRAP
If set this environment variable enables trap interrupts on x86 platforms to be generated by sfcb
in special situations.
[Note: not currently ever used]

SBLIM_TRACE
Specifies the level of trace/debug messages for SBLIM providers. Valid values are 0 (no trace
messages), or 1 (key trace messages only) to 4 (all messages).
[Note: this only applies to SBLIM providers written with explicit trace messages in their source
code.]

SBLIM_TRACE_FILE
By default SBLIM provider trace messages are written to STDERR. Setting this envorinment variable
causes the trace messages to be written to a file instead.
