Do you know if the problem comes from your (Java) local client or from the remote server which you want to monitor thru snmp?

How is configured this last one? Is Xinet working there? Is port 161 open? Any restriction on IPs allowed to probe?
rakesh kAuthor Commented:
actually i am sending request like this for authnopriv user

  snmpAdaptor.snmpV3UsmTrap(snmpInetAddress, "myuser", SnmpDefinitions.authNoPriv, "TEST-CONTEXT", serverUpOid, varList);

it giving error like this

com.sun.management.snmp.usm.SnmpUsmUserNameException: User myuser unknown.

may be due to i'am not sending md5 or sha security type,please clarify me, how to set these md5 and sh to snmpAdaptor to resolve User myuser unknown.

are you using a username that exists:   myuser unknown seems to hint otherwise.

Not sure I understand fully.
One interpretation of what you write:
1 - you want to get data thru snmp
2 - but access to the server has a first layer with auth-type login

Is that correct?
It seems that you currently have a problem with auth layer

For SNMP layer, have you whitelisted the calling IP?
Bernard S.CTOCommented:
Hi Rakesh,

Is your problem solved?
If SNMPing to a Linux host, check /etc/default/snmp as well as snmpd.conf and snmp.conf in /etc/snmp/
Bernard S.CTOCommented:
Hi Rakesh,
