SNMPD.CONF(5) OpenBSD Programmer's Manual SNMPD.CONF(5)NAMEsnmpd.conf - Simple Network Management Protocol daemon configuration file
DESCRIPTIONsnmpd.conf is the configuration file for the snmpd(8) daemon.
SECTIONS
The snmpd.conf file is divided into three 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:
listen on address
Specify the local address snmpd(8) should listen on for incoming
SNMP messages.
read-only community string
Specify the name of the read-only community. The default value
is public.
read-write community string
Specify the name of the read-write community. The default value
is private.
system contact 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.
system description 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
system location string
Specify the string describing the location of the local system,
typically a physical location. The default value is an empty
string.
system name string
Specify the name of the local system, typically a fully-qualified
domain name. The default value is the hostname of the local
system.
system oid 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)
identifying a common OpenBSD system.
system services 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.
trap community string
Specify the name of the trap community. The default value is
public.
trap receiver string [oid oid-string] [community string]
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 trap community
option.
OID CONFIGURATION
It is possible to specify user-defined OIDs in the configuration file:
oid oid-string name name [read-only | 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 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
