Fc4 Linux 上利用net-snmp进行snmpv3测试

1.download net-snmp source package from sourceforge.net.use the version 5.0.11.

2.install according to INSTALL.
    ./configure
    make
    make install
    make clean.

3.copy EXAMPLE.conf file to ~/.snmp/ as snmpd.conf,and change some configurations if needed.

4.add snmpv3 Config
snmpv3 config command:
net-snmp-config --create-snmpv3-user -ro -a authpass -x privpass -X DES -A MD5 v3username
after run ,it will modify to files.
adding the following line to /var/net-snmp/snmpd.conf:
    createUser v3user MD5 "authpass" DES privpass
adding the following line to /usr/local/share/snmp/snmpd.conf:
    rouser v3username

actually,the snmpd program uses the config file under ~/.snmp/.So add the user name
in file ~/.snmp/snmpd.conf.
at last,the Access Control section maybe like this.
---------------------------------------------------------------------------------------------
# rouser: a SNMPv3 read-only user
#   arguments:  user [noauth|auth|priv] [restriction_oid]
rouser v3username
