nut-scanner - scan communication buses for NUT devices

nut-scanner -h

nut-scanner [OPTIONS]

nut-scanner scans available communication buses and displays any NUT-compatible devices it has found.

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.

-h

Display the help text.

-N | --disp_nut_conf

Display result in the ups.conf format.

-P | --disp_parsable

Display result in a parsable format.

-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 explicitely, even for a complete scan. serial ports can be expressed in various forms:

auto to scan all serial ports.

•a single charcater 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 refering to the port number.

•a single port name.

•a list of ports name, coma separated, like /dev/ttyS1,/dev/ttyS4.

-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.

-p | --port port number

Set the port number of scanned NUT devices (default 3493).

-c | --community community

Set SNMP v1 community name (default = public).

-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 or SHA. 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 or AES. 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.

-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.

-D | --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

-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.

To scan USB devices only:

nut-scanner -U

To scan SNMP v1 device with public community on address range 192.168.0.0 to 192.168.0.255:

nut-scanner -S -s 192.168.0.0 -e 192.168.0.255

The same using CIDR notation:

nut-scanner -S -m 192.168.0.0/24

To scan NUT servers with a timeout of 10 seconds on IP range 192.168.0.0 to 192.168.0.127 using CIDR notation:

nut-scanner -O -t 10 -m 192.168.0.0/25

To scan for power supplies, through IPMI (1.5 mode) over the network, on address range 192.168.0.0 to 192.168.0.255:

nut-scanner -I -m 192.168.0.0/24 -b username -B password
