Hi.  I am trying to teach myself SNMP.  I have the Essential SNMP book 
by Douglas Mauro and Kevin Schmidt and I don't understand what I am 
doing wrong.

[jeffs@black jeffs]$ sudo snmpget -u JeffsLan -v 3 black system.sysUpTime.0
snmpget: Unknown user name
[jeffs@black jeffs]$


However, I think JeffsLan is the right value to use for the comunity name.

[jeffs@black jeffs]$ fgrep JeffsLan  /usr/share/snmp*.conf 
/etc/snmp/snmp*.conf
fgrep: /usr/share/snmp*.conf: No such file or directory
/etc/snmp/snmp.conf:defSecurityName JeffsLan
/etc/snmp/snmpd.conf:rocommunity  JeffsLan 192.168.2.0/24
/etc/snmp/snmpd.conf:rwcommunity  JeffsLan_RW 192.168.2.0/24
/etc/snmp/snmpd.conf:trapsink  black JeffsLan
/etc/snmp/snmpd.conf:trap2sink  black JeffsLan
/etc/snmp/snmpd.conf:informsink  black JeffsLan
/etc/snmp/snmpd.conf:trapcommunity  JeffsLan
[jeffs@black jeffs]$

snmpd is running.  I am running tcpdump in another window, looking for 
UDP packets on port 161 and I see nothing.  So I am very confused.  What 
am I doing wrong?


Many thanks,


Jeff
