Initial Comment:
If I execute the following commands, they all work fine:

[maint@repuda SMASH-1018]$ snmpget -v3 -u 
USERID -l authPriv -a MD5 -A PASSW0RD
 -xDES -XPASSW0RD 
10.2.0.90 .1.3.6.1.4.1.2.3.51.2.2.8.1.4.0
SNMPv2-SMI::enterprises.2.3.51.2.2.8.1.4.0 = 
INTEGER: 0
[maint@repuda SMASH-1018]$ snmpset -v3 -u

SNMPv2-SMI::enterprises.2.3.51.2.2.8.1.4.0 = 
INTEGER: 1
[maint@repuda SMASH-1018]$ snmpget -v3 -u 
USERID -l authPriv -a MD5 -A PASSW0RD
 -xDES -XPASSW0RD 
10.2.0.90 .1.3.6.1.4.1.2.3.51.2.2.8.1.4.0
SNMPv2-SMI::enterprises.2.3.51.2.2.8.1.4.0 = 
INTEGER: 1
[maint@repuda SMASH-1018]$ snmpset -v3 -u 
USERID -l authPriv -a MD5 -A PASSW0RD
 -xDES -XPASSW0RD 
10.2.0.90 .1.3.6.1.4.1.2.3.51.2.2.8.1.4.0 i 0
SNMPv2-SMI::enterprises.2.3.51.2.2.8.1.4.0 = 
INTEGER: 0
[maint@repuda SMASH-1018]$ snmpget -v3 -u 
USERID -l authPriv -a MD5 -A PASSW0RD
 -xDES -XPASSW0RD 
10.2.0.90 .1.3.6.1.4.1.2.3.51.2.2.8.1.4.0
SNMPv2-SMI::enterprises.2.3.51.2.2.8.1.4.0 = 
INTEGER: 0

If I switch to a different OID that requires an ip address 
type and read it, I get:


[maint@repuda SMASH-1018]$ snmpget -v3 -u 
USERID -l authPriv -a MD5 -A PASSW0RD
 -xDES -XPASSW0RD 
10.2.0.90 .1.3.6.1.4.1.2.3.51.2.22.3.2.1.2.1.1.8.1
SNMPv2-SMI::enterprises.2.3.51.2.22.3.2.1.2.1.1.8.1 = 
IpAddress: 10.2.0.90

All ok still.

However, if I try to set it, I get an Error in Packet, 
undoFailed.

[maint@repuda SMASH-1018]$ snmpset -v3 -u 
USERID -l authPriv -a MD5 -A PASSW0RD

Error in packet.
Reason: undoFailed
Failed object: SNMPv2-
SMI::enterprises.2.3.51.2.22.3.2.1.2.1.1.8.1

A tcpdump doesn't show me anything...either because I 
don;t know what to look for...or because it's encrypted.

However, if I try the same set with SNMPv1 instead of 
v3, I get the following trace...which looks like it has a 
problem sending the ip address ('a' type).

This is happening on both SUSE and Redhat.  The latter 
is RHEL4.0 with Update 1.  The Net-SNMP package is 
version 5.1.2 although we've tried version 5.2.1.2 with the 
same results.

The same commands work fine on the Windows Net-
SNMP version.
