I have my SNMP v3 agent running with the following access control
credentials

================================================== ==========
agentgroup root
master agentx
agentxsocket tcp:10.128.18.255:6262
agentxperms 770 770 poongs root

com2sec frederic 0.0.0.0/0 testing

createUser frederic MD5 mypassphrase DES
group groupv3 usm frederic
view all included .1 80
access groupv3 perl any noauth exact
all all all
================================================== =========

when I try the following command
snmpget -v3 -u frederic -n perl 10.128.18.255:6161 sysName.0
I get
Timeout: No Response from 10.128.18.255:6161

What could be the problem.

I tried debugging the code and found the context information "perl" is
not available in the context_subtrees [netsnmp_subtree_find_first]

Am I missing something which is very basic

Thanks in Advance
