NUTSCAN_SCAN_SNMP(3) NUT Manual NUTSCAN_SCAN_SNMP(3)NAMEnutscan_scan_snmp - Scan network for SNMP devices.
SYNOPSIS
#include <nut-scan.h>
nutscan_device_t * nutscan_scan_snmp(const char * start_ip,const char * stop_ip,long timeout, nutscan_snmp_t * sec);
DESCRIPTION
The nutscan_scan_snmp() function try to detect NUT compatible SNMP
devices. It tries SNMP queries on every IP ranging from start_ip to
stop_ip. Those IP may be either IPv4 or IPv6 addresses or host names.
You MUST call nutscan_init(3) before using this function.
This function waits up to timeout microseconds before considering an IP
address does not respond to SNMP queries.
A valid nutscan_snmp_t structure must be passed to this function.
The nutscan_snmp_t structure contains the following members which must
be filled as described below:
char * 'community';
char * 'secLevel';
char * 'secName';
char * 'authPassword';
char * 'privPassword';
char * 'authProtocol';
char * 'privProtocol';
If community is not NULL, SNMP v1 request are sent using this
community.
If community is NULL and secLevel is NULL, SNMP v1 is selected and
community is set to "public".
In the other cases, SNMP v3 is used. secLevel may be one of
SNMP_SEC_LEVEL_NOAUTH, SNMP_SEC_LEVEL_AUTHNOPRIV or
SNMP_SEC_LEVEL_AUTHPRIV. secName is the security name and must be non
NULL.
If secLevel is set to SNMP_SEC_LEVEL_AUTHNOPRIV, authPassword must be
non NULL.
If secLevel is set to SNMP_SEC_LEVEL_AUTHPRIV, authPassword and
privPassword must be non NULL.
If authProtocol is NULL, MD5 protocol is used. Else you can set
authProtocol to either "MD5" or "SHA".
If privProtocol is NULL, DES protocol is used. Else you can set
privProtocol to either "AES" or "DES".
peername and handle are used internally and do not need any
initialization.
RETURN VALUE
The nutscan_scan_snmp() function returns a pointer to a
nutscan_device_t structure containing all found devices or NULL if an
error occurs or no device is found.
