How to know if I am Pinged?

By Junaid Subhani

Dear All,

I need to build a mechanism by which I can log if any node in my DC is pinging my server or not ?

The purpose is al follows:

Incase any node in my Data Center turns off , I need to have a mechanism by which I am notified that a certain node is no longer responding.

On my Solaris system , can I know if I am being pinged ?

Regards

MoSys Announces 100G Multi-Mode Gearbox PHY for Networking and Communications Line Cards and Modules

LineSpeed™ Gearbox Extended Reach CMOS SerDes Supports 10G, 40G, and 100G IEEE and OIF Standards Used in Data Center, Enterprise and Telecom Applications

SANTA CLARA, Calif.–(BUSINESS WIRE)– MoSys (NAS: MOSY) , a leader in semiconductor solutions that enable fast, intelligent data access for network and communications systems, today announced its new LineSpeed™ 100G Multi-Mode Gearbox integrated circuit (IC) for next-generation networking and communications systems. The high-performance gearbox serializer/deserializer (SerDes) utilizes advanced equalizer technology to deliver industry-leading performance. Exploding demand for aggregate bandwidth makes it essential to increase port density of 10G, 40G, and 100G line cards for next-generation systems. MoSys’ LineSpeed device enables high-density, low-power line cards and modules for short and extended reach data path applications.

The LineSpeed MSH310 device converts 10 lanes of serial 10/11 Gbps data into 4 lanes of serial 25/28 Gbps data or 10 lanes of 10/11 Gbps data per IEEE 802.3ba, and integrates a complete CAUI and OIF-CEI-3.0 transceiver along with a 10:4 or 10:10 multiplexer and 4:10 de-multiplexer. It supports IEEE802.3ba 100G Ethernet plus OIF-CEI-3.0 10G and 25/28G specifications.

Key Features:

  • Gearbox functionality converts from 10 lanes (10×10-11Gbps) to 4 lanes (4×25-28Gbps)
  • Supports retiming of 10 lanes of 10GbE or 2 lanes of 40GbE for card and module flexibility
  • Support for 10G, 40G, and 100G IEEE and OIF standards
  • Strong adaptive equalizer with multi-tap DFE and programmable transmit equalization target CEI VSR, SR and LR reach as well as copper cable and backplane applications
  • Reverse polarity control for 10G and 28G inputs and outputs
  • Self test capabilities, such as on chip PRBS generator, bit error rate tester, eye opening and monitoring
  • Built using low-power standard CMOS technology

“The new generation of network and data center systems must support 100s of gigabits of aggregate bandwidth per line using multiple combinations of high density 10G, 40G and 100G ports,” stated John Monson, VP of Marketing at MoSys. “The LineSpeed 100G Multi-Mode Gearbox is optimized to enable …read more

Vitesse’s Intellisec Secures Communications Networks for Cloud Services


Industry’s First Solution for Cost-Effective Network-Wide Link Layer Encryption

ANAHEIM, Calif.–(BUSINESS WIRE)– Vitesse Semiconductor Corporation (NAS: VTSS) , a leading provider of advanced IC solutions for Carrier and Enterprise networks, introduced Intellisec™, its patent-pending, universal, lightweight security encryption technology for communications networks. Intellisec is the industry’s first technology to enable IEEE 802.1AE MACsec encryption end-to-end over any network, including multi-operator and cloud-based networks, independent of the network’s awareness of security protocols. Delivering up to 75% savings versus alternatives, Intellisec radically reduces the cost of securing network applications such as e-commerce, cloud services, enterprise, and government communications.

Recent reports on cybersecurity breaches highlight the need for critical network infrastructure protection, as Enterprises and Carriers alike move to cloud-based models. The security aspect also has implications for mobile 4G/LTE deployments and industrial networks. According to Hewlett-Packard’s recent 2012 Cyber Security Risk Report, total security vulnerabilities are rising, with mobile vulnerabilities having grown 68% from 2011 to 2012 alone and 787% over the last five years.

“Vitesse is changing the landscape of secure network communications with Intellisec technology,” said Martin Nuss, chief technology officer for Vitesse. “End-to-end network encryption is highly complex and prohibitively expensive to implement at Layer-3, while existing Layer-2 MACsec PHY solutions need encryption and decryption at every link in the network. Because Intellisec runs over MEF CE 2.0 and MPLS networks, it will work over most service provider networks with Intellisec-enabled equipment access devices or enterprise edge routers at network endpoints. This has never been done before.”

Intellisec: A Low-Cost, Scalable Cloud Networking Security Solution

  • Enables MACsec Networkwide: Intellisec dramatically extends MACsec to support secure access to multiple cloud services, enabling delivery of MACsec-secured Layer-2 Carrier Ethernet services, such as MEF EVCs, MPLS L2VPNs and Data Center Interconnect, across the network. Until now, MACsec has traditionally been limited to link-based box-to-box applications primarily within cloud services data centers;
  • Simple, Low-Cost, Scalable: Intellisec scales easily with the number of interfaces, delivering up to …read more

Duncan McGreggor: Erlang Meetup at Rackspace, San Francisco

I’m very pleased to announce that Rackspace‘s San Francisco office will be hosting an Erlang Meetup immediately after the closing session of last day of SF Erlang Factory on 22 March.

We are honored to announce that both Robert Virding and Francesco Cesarini will be present for the event. The night will open up at 6:30pm with Mediterranean food, refreshments (and I hear there will be a keg). Around 7:15pm we will gather for a presentation by the very talented folks at Boundary which will start at 7:30pm.

The Boundary presentation will be followed by one from Robert Virding. We’ll finish the night with a door prize give-away of two copies of Francesco and Simon’s book Erlang Programming: A Concurrent Approach to Software Development. Perhaps the winners might be able to talk Francesco into signing their copies? 😉

Last but not least, some of Rackspace’s own Erlangers will be on hand for conversations about how we’re using Erlang/OTP to deliver Fanatical Support in in our Data Center and Cloud Ops groups.

We’re going to start with a cap of 60 people for the event, but if there’s high demand, we have room to adjust this. Due to some communications hiccups, we’re going to do the planning for this event the old-fashioned way: send an email to duncan.mcgreggor@rackspace.com, and let me know that you’d like to attend. Your name will be added to the list in the order I receive emails. The list of attendees and the waiting list are published here and will be refreshed with each new addition.

As special thanks go out to Robert Virding, Phil Toland, and Brian Troutwine — conversations with them were the inspiration for putting this event together. Thanks guys! (Note that I’ve put that background info into its own blog post, so as not to confuse the event announcement … to much 😉 ).

See you at Erlang Factory SF and then on Friday at the Rackspace office!
