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.
nut-scanner can also display the detected devices in various formats, including ups.conf, and ensures that the generated devices name are unique across buses.
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
- -Q | --disp_nut_conf_with_sanity_check
-
Display result in the ups.conf format with sanity-check warnings (if any) as comments (default).
- -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.
This option can be specified several times, for more hardware link-specific details; these can be counter-productive in case of USB enumeration changes over time:
|
-U
| do not report any bus/device/busport details | |-UU
| report bus and busport, if available | |-UUU
| report bus/device/busport details | |-UUUU
| report bus/device/busport details, and bcdDevice (limited use and benefit) |NoteFor reliability, it is preferable to match just by vendor and product identification, and a serial number if available and unique. - -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. Can broadcast a network message on the current network interfaces to retrieve XML/HTTP capable devices. No IP required in this mode.
- -O | --oldnut_scan
-
Scan NUT devices (i.e. upsd daemon) on IP ranging from start IP to end IP.
- -n | --nut_simulation_scan
-
Scan NUT simulated devices (.dev files in $CONFPATH).
- -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) or optional (XML/HTTP).
- -e | --end_ip end IP
-
Set the last IP (IPv4 or IPv6) when a range of IP is required (SNMP, old_nut) or optional (XML/HTTP). 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. This parameter is mandatory if you use non-trivial authentication.
- -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 buses that can be scanned, depending on how the nut-scanner binary program has been compiled. (e.g. 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.
Note
|
The level of debugging needed depends both on nut-scanner and the
problem you’re trying to diagnose. Therefore, first explain the problem you
have with nut-scanner to a developer/maintainer, before sending them debugging
output. More often than not, if you just pick a level, the output may be
either too limited or too verbose to be of any use. |
