i don't have a sysServices.0 instance on the agent2:
when i do an snmpget on it

snmpget -v 3 -u "snmpV3_user_agent2" -A "my_pwd" -a MD5 -l authNoPriv =
"ip_agent2" system.sysServices.0

i've got the following reply:

SNMPv2-MIB::sysServices.0 =3D No Such Instance currently exists at this =
OID

the snmpwalk for system on the agent2 from the management station give:

but another thing is strange, when i do an snmpgetnext on =
system.sysServices.0 i get:

snmpgetnext -v 1 -c "agent1_community" "agent1_ip" system.sysServices.0

IF-MIB::ifNumber.0 =3D INTEGER: 34

it seams that the 34 come from there but i don't understand why it's =
associated at the system.sysServices.0 object!

i'm using net-snmp 5.0.9 on a linux red hat AS3 on the agent2.
and the agent1 is a 3com superstack3 switch.

and i've just add a second agent let's call it agent3.=20

|agent1|-------|agent2(the proxy)|--------|management station|
|
|agent3|-----------------

this agent agent is also a net-snmp 5.0.9 and the error is again the =
same.
when i do an snmpwalk on it passing through the proxy i get the =
following message:

the request:
=09
snmpwalk -v 3 -u "snmpV3_user_agent2" -A "my_pwd" -a MD5 -l authNoPriv =
"ip_agent2" system -n mali_v1

the proxy line in snmpd.conf is:
=09
proxy -Cn mali_v1 -v 1 -c "agent3_community" "ip_agent3" system

the response:

it seams that it appends always on the last OID viewed by the =
snmpwalk!!!

and when i do this snmpwalk directly from the agent2 to agent3 (without =
proxy):

request:
=09
snmpwalk -v 1 -c "agent3_community" "agent3_ip" system

i get:
