but you must have built the
package
with
openssl
installed
in
order
to use SHA.
The only privacy
protocol currently supported is DES.
If
the
pri-
vacy
passphrase is not specified, it is assumed to
be the same as the authentication passphrase.
Note
that
the users created will be useless unless they
are also added to the VACM
access
control
tables
described above.
Warning:
the minimum pass phrase length is 8 char-
acters.
SNMPv3 users can be created at
runtime
using
the
snmpusm command.
SETTING SYSTEM INFORMATION
syslocation STRING
syscontact STRING
Sets the system location and the system contact for
the agent.
This information
is
reported
by
the
’system’ table in the mibII tree.
authtrapenable NUMBER
Setting
authtrapenable
to 1 enables generation of
authentication failure traps. The default value
is
2 (disable).
trapcommunity STRING
This
defines
the
default
community string to be
used when sending traps.
Note
that
this
command
must
be
used
prior to any of the following three
commands
that
are
intended
use
this
community
string.
trapsink HOST [COMMUNITY [PORT]]
trap2sink HOST [COMMUNITY [PORT]]
informsink HOST [COMMUNITY [PORT]]
These
commands
define
the hosts to receive traps
(and/or inform notifications). The daemon
sends
a
Cold
Start
trap when it starts up. If enabled, it
also sends traps on authentication failures.
Mul-
tiple
trapsink, trap2sink and informsink lines may
be specified to specify multiple destinations.
Use
trap2sink
to
send
SNMPv2 traps and informsink to
send inform notifications.
If
COMMUNITY
is
not
specified,
the
string from a preceding trapcommu-
nity directive will be used. If PORT is not
speci-
fied,
the
well known SNMP trap port (162) will be
used.
