NAME¶
nut-scanner - scan communication buses for NUT devices
SYNOPSIS¶
nut-scanner -h
nut-scanner [OPTIONS]
DESCRIPTION¶
nut-scanner scans available communication buses and
displays any NUT-compatible devices it has found.
INSTALLATION¶
nut-scanner is only built if libltdl (part of libtool
development suite) is available. Available options (USB, SNMP, IPMI, ...)
will vary according to the available compile time and runtime dependencies.
For example, if Net-SNMP is installed, thus providing libsnmp (.so or .dll)
and headers, both during compilation and runtime, then SNMP discovery will
be available.
OPTIONS¶
-h
Display the help text.
DISPLAY OPTIONS¶
-N | --disp_nut_conf
Display result in the ups.conf format.
-P | --disp_parsable
Display result in a parsable format.
BUS OPTIONS¶
-C | --complete_scan
Scan all available communication buses (default
behavior)
-U | --usb_scan
List all NUT-compatible USB devices currently plugged
in.
-S | --snmp_scan
Scan SNMP devices. Requires at least a start IP,
and optionally, an end IP. See specific SNMP OPTIONS for community and
security settings.
-M | --xml_scan
Scan XML/HTTP devices. Broadcast a network message on the
current network interfaces to retrieve XML/HTTP capable devices. No IP
required.
-O | --oldnut_scan
Scan NUT devices (i.e. upsd daemon) on IP ranging from
start IP to end IP.
-A | --avahi_scan
Scan NUT servers using Avahi request on the current
network interfaces. No IP required.
-I | --ipmi_scan
Scan NUT compatible power supplies available via IPMI on
the current host, or over the network.
-E | --eaton_serial serial ports
Scan Eaton devices (XCP and SHUT) available via serial
bus on the current host. This option must be requested explicitly, even for a
complete scan.
serial ports can be expressed in various forms:
•auto to scan all serial ports.
•a single character indicating a port number
(0 (zero) for /dev/ttyS0 and /dev/ttyUSB0 on Linux, 1 for COM1
on Windows, a for /dev/ttya on Solaris...)
•a range of N characters, hyphen separated,
describing the range of ports using X-Y, where X and Y are characters
referring to the port number.
•a single port name.
•a list of ports name, coma separated, like
/dev/ttyS1,/dev/ttyS4.
NETWORK OPTIONS¶
-t | --timeout timeout
Set the network timeout in seconds. Default timeout is 5
seconds.
-s | --start_ip start IP
Set the first IP (IPv4 or IPv6) when a range of IP is
required (SNMP, old_nut).
-e | --end_ip end IP
Set the last IP (IPv4 or IPv6) when a range of IP is
required (SNMP, old_nut). If this parameter is omitted, only the start
IP is scanned. If end IP is less than start IP, both
parameters are internally permuted.
-m | --mask_cidr IP address/mask
Set a range of IP using CIDR notation.
NUT DEVICE OPTION¶
-p | --port port number
Set the port number of scanned NUT devices (default
3493).
SNMP V1 OPTION¶
-c | --community community
Set SNMP v1 community name (default = public).
SNMP V3 OPTIONS¶
-l | --secLevel security level
Set the security level used for SNMPv3 messages.
Allowed values are: noAuthNoPriv, authNoPriv and authPriv.
-u | --secName security name
Set the security name used for authenticated
SNMPv3 messages. This parameter is mandatory if you set security
level.
-w | --authProtocol authentication
protocol
Set the authentication protocol used for
authenticated SNMPv3 messages. Allowed values are MD5, SHA, SHA256, SHA384 or
SHA512 (depending on Net-SNMP library capabilities; check help of the
nut-scanner binary program for the run-time supported list). Default value is
MD5.
-W | --authPassword authentication pass
phrase
Set the authentication pass phrase used for
authenticated SNMPv3 messages. This parameter is mandatory if you set
security level to authNoPriv or authPriv.
-x | --privProtocol privacy protocol
Set the privacy protocol used for encrypted SNMPv3
messages. Allowed values are DES, AES, AES192 or AES256 (depending on Net-SNMP
library capabilities; check help of the nut-scanner binary program for the
run-time supported list). Default value is DES.
-X | --privPassword privacy pass phrase
Set the privacy pass phrase used for encrypted
SNMPv3 messages. This parameter is mandatory if you set security level
to authPriv.
IPMI OPTIONS¶
-b | --username username
Set the username used for authenticating IPMI over LAN
connections (mandatory for IPMI over LAN. No default).
-B | --password password
Specify the password to use when authenticating with the
remote host (mandatory for IPMI over LAN. No default).
-d | --authType authentication type
Specify the IPMI 1.5 authentication type to use (NONE,
STRAIGHT_PASSWORD_KEY, MD2, and MD5) with the remote host (default=MD5). This
forces connection through the lan IPMI interface , thus in IPMI 1.5
mode.
-L | --cipher_suite_id cipher suite
identifier
Specify the IPMI 2.0 cipher suite ID to use. The Cipher
Suite ID identifies a set of authentication, integrity, and confidentiality
algorithms to use for IPMI 2.0 communication. The authentication algorithm
identifies the algorithm to use for session setup, the integrity algorithm
identifies the algorithm to use for session packet signatures, and the
confidentiality algorithm identifies the algorithm to use for payload
encryption (default=3).
The following cipher suite ids are currently supported
(Authentication; Integrity; Confidentiality):
•0: None; None; None
•1: HMAC-SHA1; None; None
•2: HMAC-SHA1; HMAC-SHA1-96; None
•3: HMAC-SHA1; HMAC-SHA1-96;
AES-CBC-128
•6: HMAC-MD5; None; None
•7: HMAC-MD5; HMAC-MD5-128; None
•8: HMAC-MD5; HMAC-MD5-128;
AES-CBC-128
•11: HMAC-MD5; MD5-128; None
•12: HMAC-MD5; MD5-128; AES-CBC-128
•15: HMAC-SHA256; None; None
•16: HMAC-SHA256; HMAC_SHA256_128;
None
•17: HMAC-SHA256; HMAC_SHA256_128;
AES-CBC-128
MISCELLANEOUS OPTIONS¶
-V | --version
Display NUT version.
-a | --available
Display available bus that can be scanned , depending on
how the binary has been compiled. (OLDNUT, USB, SNMP, XML, AVAHI, IPMI).
-q | --quiet
Display only scan result. No information on currently
scanned bus is displayed.
-D | --nut_debug_level
Raise the debugging level. Use this multiple times to see
more details.
