snmpd - a server for supplying SNMP management information
SYNOPSIS
snmpd
[-d]
[-A]
[-N]
DESCRIPTION
The
snmpd
daemon is a server (agent)
implementing the Simple Network Management Protocol
for the NeXT Computer.
An SNMP agent supports a management information base (MIB)
consisting of a set of variables layed out in a tree.
The variables and their types
are defined using ASN.1
and are listed in /etc/snmp.mib.
The management base currently implemented by
snmpd
is that of MIB-I,
as defined by RFC1156.
The
snmpd
server should always be run as root
because it needs to open a privileged socket
in order to receive its queries.
The current implementation also
needs to read /dev/kmem
in order to obtain the information necessary
to describe the running system.
By default,
snmpd
will only allow access to hosts
listed in NetInfo by name, address, or network number.
This can be overridden by supplying the
-A
option when starting
snmpd,
which will allow any network entity
access to the information in your SNMP agent.
To grant individual hosts or networks access explicitly,
first decide on a community name (e.g. ``public'')
and create a subdirectory of
/locations/snmp/communities
with that name.
Then create a property named
hosts
or
networks
in that directory
and list the host names or network numbers
from which you wish to allow queries.
Hosts should be specified using their official hostname
as returned by
gethostbyname.3
networks should be in dot notion.
An asterisk (``*'') in either of these properties
will match any host or network
and open access to any host on the internet.
OPTIONS
- -d
-
Turn on debugging output.
Each time a packet is received or sent,
a hexadecimal dump its contents
will be produced on standard output.
- -A
-
Allow anyone access to the SNMP server.
By default, only hosts or other management entities
listed in in the
/locations/snmp/communities
directories in NetInfo
will have access to the information in local SNMP server.
See below under Access Control for more details.
- -N
-
Only run if enabled in NetInfo.
This option will cause
snmpd
to quit immediately unless the
enabled
property in NetInfo's
/locations/snmp
directory has a value of
YES.
This is used to start
snmpd
automatically
from /etc/rc.
NOTE
The current implementation of the SNMP server
is based on a public domain package
and is copyright 1988, 1989 by Carnegie Mellon University.
