Snmp login with v1,v2c,
V3
There is 3 version of snmp :
V1 : you need a community to log in
:
<script> -C <community>
V2c : you need a community to log in
:
<script> -C <community>
-2
V3 : you need a login and password.
You can either encrypt data (AuthPriv) or not (AuthNoPriv). Authentication
is encrypted in any case : NoAuthNoPriv is not supported, and is
useless anyway : use snmpv1 in this case.
AuthNoPriv : Data is sent in clear,
login and password are encrypted.
With default protocol (md5) :
<script> -l login -x passwd
With sha protocol :
<script> -l login -x passwd -L
sha
AuthPriv : Data, login and password
are encrypted
With default protocol (md5,des) :
<script> -l login -x passwd -X
privpasswd
With md5 for logging and aes for encrypting :
<script> -l login -x passwd -X
privpasswd -L md5,aes
