SNMP Extend MIB on Ubuntu snmpd 5.4.1


I am trying to get the EXTEND feature of SNMPD to work. I have added this at the end of my snmpd.conf file.

Code:
extend datecheck /bin/date
and after restarted snmpd I get this error when I try to walk for my new "extension"

Code:
No more variables left in this MIB View (It is past the end of the MIB tree)
Here is the full output of all my walks.

Code:
me@testserver:~$ snmpwalk -v 2c -c public localhost UCD-SNMP-MIB::extTable
UCD-SNMP-MIB::extTable = No more variables left in this MIB View (It is past the end of the MIB tree)
me@testserver:~$ snmpwalk -v 2c -c public localhost NET-SNMP-EXTEND-MIB::nsExtendResult
NET-SNMP-EXTEND-MIB::nsExtendResult = No more variables left in this MIB View (It is past the end of the MIB tree)
me@testserver:~$ snmpwalk -v 2c -c public localhost NET-SNMP-EXTEND-MIB::nsExtendOutput1Table
NET-SNMP-EXTEND-MIB::nsExtendOutput1Table = No more variables left in this MIB View (It is past the end of the MIB tree)
me@testserver:~$ snmpwalk -v 2c -c public localhost NET-SNMP-AGENT-MIB::nsExtensions
NET-SNMP-AGENT-MIB::nsExtensions = No more variables left in this MIB View (It is past the end of the MIB tree)
and here is my snmpd.conf file

Code:
com2sec paranoid  default         public

group MyROSystem v1        paranoid
group MyROSystem v2c       paranoid
group MyROSystem usm       paranoid
group MyROGroup v1         readonly
group MyROGroup v2c        readonly
group MyROGroup usm        readonly
group MyRWGroup v1         readwrite
group MyRWGroup v2c        readwrite
group MyRWGroup usm        readwrite

view all    included  .1                               80
view system included  .iso.org.dod.internet.mgmt.mib-2.system

access MyROSystem ""     any       noauth    exact  system none   none
access MyROGroup ""      any       noauth    exact  all    none   none
access MyRWGroup ""      any       noauth    exact  all    all    none

syslocation Unknown (configure /etc/snmp/snmpd.local.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmpd.local.conf)

extend datecheck /bin/date
so can anyone tell me what I'm doing wrong?

Thanks

Ok, so it is my snmpd.conf file because this works.

Code:
rocommunity  public
group MyROGroup v2c        readonly
view all    included  .1                               80
access MyROGroup ""      any       noauth    exact  all    none   none
extend datecheck /bin/date
I don't quite understand these settings, can anyone help me identify what it is in the original that is causing the problem. I assume the "view" is the culprit.

And right now I can do an snmpwalk locally, but not remotely. What can I add to allow remote reads?

Thanks,
