SNMPv3 Traps with authPriv now supported

Unbrowse SNMP already has a powerful trap receiver. It supports SNMPv1, v2, v3 and IPv4 and IPv6. It can also run authentication checks on incoming traps. However, it could not decrypt SNMPv3 traps sent in authPriv mode.

Our latest release of Unbrowse SNMP now has the ability to decrypt SNMPv3 traps and show the results in the trap console. All auth protocols (MD5 and SHA) and privacy protocols (DES and AES-128) are supported.

Enjoy !

How to use ?

To make it work you need to enter the security information for each agent from which you are expecting a trap. Use the Agents > Manage menu to create the agent and user.

Next enable this feature,

  • Select Tools > Customize > Advanced, Locate the Trap Console group in the Miscellaneous box
  • Find the last item “Try to decrypt authPriv traps” - and check it
  • You may also want to check “Authenticate incoming traps” ( 4 items up the list from the above)
  • See the screen below for the recommended options !

Now, incoming traps will be matched against the agent database. If there is a matching entry for User Name and the IP Address, the passwords specified by you will be used to decrypt and authenticate the trap.

TRAI allows internet telephony – LI made mandatory

You may finally be able to call a fixed line or mobile from your computer in India. In a major move, the TRAI (Telecom Regulatory Authority of India) has allowed ISPs to provide unrestricted internet telephony.

From Indiatimes

According to TRAI, TEC (Telecommunication Engineering Centre) will identify distinct number resources for Internet telephony subscribers. Telephone numbers from the identified blocks will be allocated to ISPs, UASPs (unified access service providers), BSOs (basic service operators) and CMSPs (cellular mobile service providers) for Internet telephony.

 

This is exciting news for all VoIP products and professionals in India. As expected, all ISPs must mandatorily invest in lawful intercept technology.  Now, that is interesting for Unleash Networks.

Indian ISPs, we have the perfect solution for you. Trisul – our open source network forensics package is capable of real time analysis of VoIP calls, metering of traffic, call (audio/video) recording and on demand reproduction and much more.
