Argh!!

Sorry Greg, this is the correct syntax:

root at bizio:/home/rizla/net-snmp-5.0.8# snmpwalk -v 1 -c community localhost
.1.3.6.1 |grep -i ucd
SNMPv2-SMI::mib-2.25.4.2.1.5.27578 = STRING: "-i ucd"
UCD-SNMP-MIB::memIndex.0 = INTEGER: 0
UCD-SNMP-MIB::memErrorName.0 = STRING: swap
UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 530136
UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 473212
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 255472
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 9064
UCD-SNMP-MIB::memTotalFree.0 = INTEGER: 482276
UCD-SNMP-MIB::memMinimumSwap.0 = INTEGER: 16000
....

Now Am I able to lunch cfgmaker ? 
Thanks
