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.

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 devices available via IPMI on the current host.

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.

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.

EXAMPLES
       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 192.168.0.128 using CIDR notation:

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