Command line arguments

Configuration directives from configuration files (relative to the given binary) could be passed via command line too. For this specify it like this:

--CONF_DIRECTIVE="VALUE1[ VALUE2...]"

Example:

snmpd --rwcommunity="public "

There are also command line arguments, which are binary specific and can be retrieved via calling the binary with --help directive. Some of them could not be configured via configuration files. Next table will explore some important options, which could be used by master, agents and SNMP tools.

Option	Description
General options
-m MIBLIST	use MIBLIST instead of the default MIB list
-M DIRLIST	use DIRLIST as the list of locations to look for MIBs
-d	Dump (in hexadecimal) the raw SNMP packets sent and received.
-D[TOKEN[,...]]	Turn on debugging output for the given TOKEN(s). For specific available tokens, please refer to section “Debug options”.
-H	Display a list of configuration file directives understood by the command and then exit.
-f	do not fork from the shell
-p FILE	store process id in FILE
-L	Logging options
-Le	Log messages to the standard error stream.
-Lf FILE	Log messages to the specified file.
-Lo	Log messages to the standard output stream.
-Ls FACILITY	Log messages via syslog, using the specified facility: 'd' for LOG_DAEMON,'u' for LOG_USER,'0'-'7' for LOG_LOCAL0 - LOG_LOCAL7)
-LE pri	Log messages of priority 'pri' and above to standard error.
-LS pri	similar as previous, but logging to syslog
-LE p1-p2	Log messages with priority between ‘p1’ and 'p2' (inclusive) to standard error.
-LS p1-p2	similar as previous, but logging to syslog
Daemons specific options
-c FILE[,...]	read FILE(s) as configuration file(s)
-C	do not read the default configuration files
-x ADDRESS	use ADDRESS as AgentX address
-X	run as an AgentX master
snmpd specific options
-a	log addresses
-q	print information in a more parsable format
snmptrapd options
-a	ignore authentication failure traps
-n	use numeric addresses instead of attempting hostname lookups (no DNS)
-t	Prevent traps from being logged to syslog

For -LF and -LS the priority specification comes before the file or facility token. The priorities recognized are:

Priority levels	Means
0 or !	LOG_EMERG
1 or a	LOG_ALERT
2 or c	LOG_CRIT
3 or e	LOG_ERR
4 or w	LOG_WARNING
5 or n	LOG_NOTICE
6 or i	LOG_INFO
7 or d	LOG_DEBUG

By default, output is logged to the syslog at a priority level of LOG_INFO.
