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

       -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.

       -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.

       -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

           •   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 nut-scanner binary
           program has been compiled. (OLDNUT, USB, SNMP, XML, AVAHI, IPMI).
