AUTHKEY (1)
create authKey for cmu snmpd and cmu managing applications
SYNOPSIS
authKey <password> <agentID>
DESCRIPTION
Authkey creates a 32 octet authKey from a password of your choice and
12 octet agent id. The result is printed in hex to stdout of the form:
key for 'nase' = 05a1483bb7a0b314cc5cf9d27aee2a89
OPTIONS
<password>
The passwort string. this can be any string like
Joe
or
Sec88ret.
<agentID>
The agentid should be a a string of 24 hex characters without a
leading 0x.
EXAMPLES
About The Community Argument
The agent and applications are all SNMPv1/SNMPv2c/SNMPv2u compatible.
The version is that the application will use is selected by inspecting
the first character of the community string provided to the
application, as follows:
o
if the first character of the community string is a "+" then
the SNMPv2c (community-based SNMPv2 as specified in RFC 1901)
is used (the remainder of the community string is used as the
actual community string);
o
if the first character of the community string is a "/" then
the SNMPv2u (User-based security model) is used (see the note
below for more details);
o
all other community strings select SNMPv1.
A community string that begins with a slash selects the SNMPv2u
protocol. The "community" string is parsed to build the parameters
for the communication. The format of the string is:
/userName/[authKey]/[privKey]/[contextSelector]
Trailing slashes may be omitted. Both authKey and privKey may be
specified as hex or as a human readable password. To specify a hex
key, the key must begin with "0x" and be followed by exactly 32 hex
digits (to form a 16 octet key). If a human readable password is
entered, the password is passed through the "password to key algorithm"
to generate the 16 octet key. The password to key algorithm is
specified in the "User-Based Security Model for SNMPv2" RFC.
A "+" or "/" character may not start a SNMPv1 community string and may
not be contained within any SNMPv2 parameters (this is an
*implementation* restriction).
Some "community" string examples:
/joe -- qos=noAuth/noPriv, context="", userName="joe"
/boneless/chicken/ranch -- qos=auth/priv, context="", userName="boneless"
authKey=pw2key("chicken"), privKey=pw2key("ranch")
*note* privacy not supported, trying this will generate
a UnsupportedQoS report.
/maplesyrup/sugarbush//other
-- qos=auth/noPriv, context="other", userName="maplesyrup"
authKey=pw2key("sugarbush",agentID)
/glenn/0x4ca25023b00a6689ef21cb1b6fa9cb0e
-- qos=auth/noPriv, context="", userName="glenn"
authKey=4ca25023b00a6689ef21cb1b6fa9cb0e
(the authKey is keyed using an agentID)
+public -- SNMPv2c using public as the community string
public -- SNMPv1 using public as the community string
