NUT-SCANNER(8) ============== 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 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* SEE ALSO -------- linkman:ups.conf[5] INTERNET RESOURCES ------------------ The NUT (Network UPS Tools) home page: http://www.networkupstools.org/
