NAME

snmpd.conf — configuration file for the SNMP daemon

DESCRIPTION

snmpd.conf is the configuration file for the snmpd(8) daemon.

SECTIONS

The snmpd.conf file is divided into 3 main sections.
Macros
User-defined variables may be defined and used later, simplifying the configuration file.
Global Configuration
Global runtime settings for snmpd(8).
OID Configuration
Custom configuration of SNMP object identifiers and values.

Comments can be put anywhere in the file using a hash mark (‘#’), and extend to the end of the current line.

Additional configuration files can be included with the include keyword, for example: 

include "/etc/snmpd.conf.local"

MACROS

Macros can be defined that will later be expanded in context. Macro names must start with a letter, and may contain letters, digits and underscores. Macro names may not be reserved words (for example, community, system, or oid)). Macros are not expanded inside quotes.

For example: 

ext_addr="192.168.0.1"
listen on $ext_addr

GLOBAL CONFIGURATION

The following options can be set globally:

listenon address
Specify the local address snmpd(8) should listen on for incoming SNMP messages.

read-onlycommunity string
Specify the name of the read-only community. The default value is public.

read-writecommunity string
Specify the name of the read-write community. The default value is private.

systemcontact string
Specify the name or description of the system contact, typically a name or an e-mail address. The default value is root@hostname using the hostname of the local machine.

systemdescription string
Specify a description of the local system. The default value is the operating system identification as printed by the uname(1) command using the -a flag: 

OpenBSD myhost.example.com 4.2 GENERIC#595 i386

systemlocation string
Specify the string describing the location of the local system, typically a physical location. The default value is an empty string.

systemname string
Specify the name of the local system, typically a fully-qualified domain name. The default value is the hostname of the local system.

systemoid oid-string
Specify the authoritative identification of the local system. The default value is 1.3.6.1.4.1.30155.23.1 (iso.org.dod.internet.private.enterprises.openbsd.23.1) indentifying a common OpenBSD system.

systemservices number
Specify a magic value which indicates the set of services that the local system may provide. Refer to the sysServices description in the SNMP MIB for details.

trapcommunity string
Specify the name of the trap community. The default value is public.

trapreceiver string [oidoid-string] [communitystring] Specify the address or FQDN of a remote trap receiver for outgoing traps sent by snmpd(8). This option may be specified multiple times. The daemon will send outgoing traps using the revised SNMPv2 format and the configured trap community. The default community is specified by the global trapcommunity option.

OID CONFIGURATION

It is possible to specify user-defined OIDs in the configuration file:

oidoid-string namename [read-only\*(Ba\ read-write] [type] value Return the specified value to the client for this OID. The read-write option may allow the client to override it, and the type is is either string or integer.

FILES

/etc/snmpd.conf
Default location of the configuration file.

EXAMPLES

The following example will tell snmpd(8) to listen on localhost, override the default system OID, set the magic services value and provides some custom OID values: 

listen on 127.0.0.1

system oid 1.3.6.1.4.1.30155.23.2
system services 74

oid 1.3.6.1.4.1.30155.42.1 name myName read-only string "humppa"
oid 1.3.6.1.4.1.30155.42.2 name myStatus read-only integer 1
