/etc/snmp/snmp.conf - configuration file for the ucd-snmp applications.
~/.snmp/snmp.conf - personal configuration file.


snmp.conf is the configuration file which define how the ucd-snmp SNMP applications operate. Tokens that can be put in them are described in the DIRECTIVES section below.


Make sure you make these files read-only by the user if you are storing sensitive information in them like pass-phrases!

First, make sure you have read the snmp_config(5) manual page that describes how the ucd-snmp configuration files operate, where they are located and how they all work together.


mibdirs (mib-dirs|+mib-dirs)

Look for textual mibs to parse in the list of ’:’ separated directories. If the directive value starts with a ’+’ it prepends this list to the front of the default directory list compiled into the application. Note that this value can be overridden by the MIBDIRS environment variable.

mibs (mib-tokens|+mib-tokens)

Specifies a ’:’ separated list of mib tokens that represent textual mib files that should be found and parsed. If the directive value starts with a ’+’ it prepends this list to the front of the default mib token list compiled into the application. The special keyword of "ALL" forces all mibs files found to be read. Note that the value specified here can be overridden by the MIBS environment variable.

mibfile file

Specifies a textual mib file to read and parse, in addition to the list read from the mibs token. Note that the value specified here can be overridden by the MIBFILES environment variable.

defaultPort port

The default port number that all snmp applications and demons should use.

defVersion (v1|v2c|v3)

The default snmp version to use.

defCommunity string

The default snmpv1 and snmpv2c community string to use.

defSecurityName string

The default snmpv3 USM security name you want to use for snmpv3 requests.

defContext string

The default snmpv3 context name you want to use.

defPassphrase string
defAuthPassphrase string
defPrivPassphrase string

The default snmpv3 USM passphrase(s) to use. defPassphrase will be used for both authentication and privacy pass phrases if it is specified.

defAuthType MD5|SHA

The snmpv3 USM authentication type to use. Only MD5 is supported out of the box at this time.

defPrivType DES

The snmpv3 USM privacy type to use. Currently, only DES is the possible value, and isn’t supported out of the box due to U.S. export restrictions.

defSecurityLevel noAuthNoPriv|authNoPriv|authPriv

The snmpv3 default security level to use.

showMibErrors (1|yes|true|0|no|false)

Whether or not to display textual mib parsing errors when commands are run.

strictCommentTerm (1|yes|true|0|no|false)

Whether or not mibs that are parsed should be strict about comment termination. "--" terminates a comment if this is true. Many distributed mibs have broken comments in them, hence this option.

mibAllowUnderline (1|yes|true|0|no|false)

Allow underline characters in mibs (illegal).

mibWarningLevel integerValue

The minimum warning level of the warnings printed by the mib parser.

logTimestamp (1|yes|true|0|no|false)

Whether the commands should log timestamps with their error/message logging or not. Note that output will not look as pretty with timestamps if the source code that is doing the logging does incremental logging of messages that are not line buffered before being passed to the logging routines.

printNumericEnums (1|yes|true|0|no|false)

Equivalent to -Oe

printNumericOids (1|yes|true|0|no|false)

Equivalent to -On

dontBreakdownOids (1|yes|true|0|no|false)

Equivalent to -Ob

escapeQuotes (1|yes|true|0|no|false)

Equivalent to -OE

quickPrinting (1|yes|true|0|no|false)

Equivalent to -Oq

suffixPrinting (0|1|2)

If the value is 1, its equivalent to -Os and if the value is 2 it’s equivalent to -OS.

extendedIndex (1|yes|true|0|no|false)

Equivalent to -OX

noRangeCheck (1|yes|true|0|no|false)

disables the validation of values that is done by snmpset before issuing the request to the agent.

dumpPacket (1|yes|true|0|no|false)

Whether the commands should dump packets by default.

doDebugging (1|0)

Turns on debugging for all applications run if set to 1.

debugTokens token[,token...]

The debugging tokens that should be printed. See the snmpcmd(1) manual page for debugging usage details.
