Security researchers claim to have discovered an SNMP flaw that affects several models of Internet-connected devices. Presumably hackers could send random values in specific requests to the SNMP agent in various devices and the authentication mechanism would be bypassed …

Despite what one might read in certain techno-marketing publications, IPv4 is very much alive; it has not by any stretch yet been replaced by IPv6. So it remains important that vendors of networking products do IPv4 and do it correctly.

But some vendors appear to be getting lazy …

Cisco Systems recently announced a patch for a vulnerability in Simple Network Management Protocol (SNMP) functions of some Cisco routers. This vulnerability could allow an authenticated, remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to an incorrect initialized variable …

IWL provides the SilverCreek SNMP Test Suite, Libraries and APIs for engineers to find and fix bugs in their SNMP agent implementations. Often developers and quality assurance engineers will need to test the SNMP management application to be used with a new SNMP agent. Verifying SNMP-based network management applications requires an SNMP agent simulator …

The world is an imperfect place. The internet is no exception. The internet has its good days and it has its bad days. Or to be more precise, the internet has its good seconds and its bad seconds.

Blemishes in internet performance arise from many sources …

The IPv6 Ready certification program addresses RFC Conformance and Interoperability. "RFC Conformance" mean the tests verify that the DUT (device under test) does what it is supposed to do based on the RFC specifications. "Interoperability" means the tests verify that the DUT can send and receive IPv6 datagrams to and from other devices …

DARPA announced in June 2014, that the DRC Finals would have a different structure than the Trials. In particular, Communications will be further degraded and intermittent forcing the robots to act more autonomously in completing their tasks. After reviewing the capabilities of all IWL’s Maxwell Network emulation products, the Maxwell Pro was chosen for its advanced programmatic capabilities …
