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

           o   auto to scan all serial ports.

           o   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...)

           o   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.

           o   a single port name.

           o   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 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.

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.

       -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):

           o   0: None; None; None

           o   1: HMAC-SHA1; None; None

           o   11: HMAC-MD5; MD5-128; None

           o   12: HMAC-MD5; MD5-128; AES-CBC-128

           o   15: HMAC-SHA256; None; None

           o   16: HMAC-SHA256; HMAC_SHA256_128; None

           o   17: HMAC-SHA256; HMAC_SHA256_128; AES-CBC-128
