Belden’s Lumberg Automation Brand Adds the LioN-R Series for PROFINET and EtherNet/IP Applications

ST. LOUIS–(BUSINESS WIRE)– Belden Inc., a global leader in signal transmission solutions for mission-critical applications, has extended its Lumberg Automation product line in the Americas region to include three new I/O modules featuring industrial protection class IP67. They provide secure connection between actuators/sensors and control units even under the harshest environmental conditions. Providing additional support for real-time (RT) and isochronous real-time (IRT) communication, the modules offer 16 digital channels configured as inputs, outputs or a combination of both. All versions come with an encapsulated metal housing, vibration-resistant M12 connection technology and short-circuit proof outputs. Galvanic separation between the I/O channels and the LAN connection ensures reliable data transmission. The behavior of output channels in the event of a fault can be defined via a fail-safe function (PROFINET). What’s more, the easy diagnostics concept allows faults to be located swiftly. An integrated dual-port switch (10/100 Mbit/s) allows both line and ring topologies.

Designed to operate in more extreme environments, the I/O modules have an operating temperature range of -10°C to +60°C and a 24VDC power supply for industrial environments.

Both LAN ports are equipped with four-pole M12 connectors with D coding. The 16 I/O sockets, each of which can send and/or receive two digital signals, have five-pole A-coded M12 connectors. To prevent confusion, both the I/O connectors and the network ports are color-coded.

The IP address for the modules is set up via the BOOTP or DHCP protocol. The controller user interfaces can be used for direct configuration of the modules. The optimum arrangement of the I/O slots makes them easy to use, even with T distributors.

Hiyam Wakeem, product manager for Lumberg Automation, adds insight to the LioN-R for PROFINET: “Key differentiator features relative to the competition are the fail safe function, high temperature range and full galvanic isolation. LioN-R can be integrated with the Lumberg LioN-Link product offering.”

She goes on to add, “LioN-R modules for the EtherNet/IP application are ruggedized and provide maximum security for EtherNet/IP data communication, guaranteeing highly productive machines and systems.”

Wipro and Infoblox Partnership Agreement Extends Network Control to Global Organizations

BANGALORE, India & SANTA CLARA, Calif.–(BUSINESS WIRE)– Infoblox Inc., the automated network control company, and Wipro Infotech, IT Business unit of Wipro Ltd., today announced a global reseller arrangement to give businesses and public organizations greater control over their corporate IT networks.

“IT leaders are looking for technology solutions that help them grow their businesses, reduce costs and achieve the balance needed to influence business strategy while also providing top-notch IT support,” said Anuj Bhalla, VP & BU Head, System Integration and Maintenance Services, Global Infrastructure Services, Wipro Limited. “As IT is becoming closely aligned to business, the need to reduce growing complexity in networks is becoming critical. Wipro and Infoblox are offering the right mix of technologies for Telecom Service Providers, Internet Service Providers, and any other large enterprise having similar requirements.”

The increasing demands put on networks by mobile devices and bring-your-own-device programs, virtualization and private clouds, and the transition to IPv6 have created greater complexity and risk for IT teams to manage. Through this reseller arrangement, Wipro will deliver Infoblox technology to help customers automate network control functions like DNS, DHCP and IPAM (known as DDI) to reduce complexity and costs, increase security and maximize uptime. Instead of adding manual processes and increasing network bandwidth, IT teams can more effectively control their networks, and free up resources to focus on strategic projects that create business value.

Cannot make pipe for process substitution: Too many open files

Leave a comment

By CiCa

Hi,

I’ve came across an issue with a script I’ve been writing to check DHCP addresses on an Solaris system, the script has been running reasonably well, until it hit the following problem:

Code:
./sub_mon_v2: redirection error: cannot duplicate fd: Too many open files
./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: line 45: <(echo $result | awk -F"/" '{print $1,$2,$3}'): ambiguous redirect

./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: line 45: <(echo $result | awk -F"/" '{print $1,$2,$3}'): ambiguous redirect

./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: line 45: <(echo $result | awk -F"/" '{print $1,$2,$3}'): ambiguous redirect

./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: cannot make pipe for process substitution: Too many open files
./sub_mon_v2: line 45: <(echo $result | awk -F"/" '{print $1,$2,$3}'): ambiguous redirect

I’m pretty sure this is down to scrappy coding (with me being the culprit – I’m still learning :)).

Is there anyone here that could maybe provide a few pointers as to how I can clean up the following function to try and fix the problem displayed above (I’ve higlighed what is almost certainly the problem line in bold):

Code:
check ()
{
> $low_subs

# Following line creates the list of subnets to check (minus the exempt subnets).
/usr/xpg4/bin/grep -vxFf $final_list

while read line
do
while read result
do
#Read each the date for each IP address in Day Month Year variables for checking
read month day year < <(echo $result | awk -F"/" '{print $1,$2,$3}')

# if it expired in a previous year, bin it

Synology DS213air review: Wireless feature doesn't add enough value

Leave a comment

The $300 Synology DS213air is a decent two-bay NAS box whose main claim to fame is its ability to perform as an 802.11 b/g Wi-Fi access point. The unit streams media quite well; however, its name is a bit misleading in that the DS213air has more in common with the $200 DS212j than the significantly faster $300 DS213. The DS213air’s wireless feature isn’t all that unique either, since you can turn add similar functionality to any current Synology NAS box using an inexpensive third-party USB 802.11 adapter. On the upside, this router sports Synology’s usual bountiful array of software features.

The DS213air uses a 1.6GHz Marvell Kirkwood mv6282 single-core CPU, and it sports 256MB of system memory. Our review unit arrived populated with two 1TB Seagate Barracuda drives in RAID 1 (mirrored). Using those components, the DS213air wrote our 10GB mix of smaller files and folders at 35.5MBps and read them at 38.3MBps. With our single large 10GB file, its performance increased to 43.6MBps writing and 74.5MBps reading. Those numbers aren’t bad, but they’re slower than what we see from most of the competition these days.

I also tested the DS213air’s streaming ability with a third-generation iPad, an Asus S7 laptop, and a slower Acer 7250 laptop. Music, photos, and even 1080p video streamed smoothly to all, though as with any Wi-Fi, your proximity and environment will impact results. Note that you must first configure the DS213air using wired Ethernet, pull the Ethernet cable, power down, and then power up again before the DLNA server will choose the Wi-Fi rather than wired network.

Synology’s operating system (along with QNAP‘s) stands head and shoulders above the rest of the competition for breadth of features. The short list includes DHCP, mail and website serving, DLNA and iTunes media serving, free one-camera video surveillance, Web-based photo/video/music serving, FTP, SFTP, HTTPS, and the usual administration features. That makes it a small business server in everything but name. A demo on Synology’s Web site lets you play with many of the features. You can check it out here.

Network Config on Zone in a Guest LDOM

Leave a comment

By os2mac

Solaris for Sparc 11.1 with the latest patches. Created a Guest LDOM with two vnet’s net0 and net1, installed a guest whole root, ip exclusive zone that I want to be able to utilize DHCP. I have been able to create the zone but unable to get it to boot because I am unable to assign an anet to it. it doesn’t matter which vnet I associate it with or what settings I change in zoncfg the anet will not configure. I have read in the documentation that anet associated with vnic or vsw is not supported but I dont’ see another way to do this.

any help would be appreciated.

Can't get DHCP IP

Leave a comment

By oobin168

Dear Experts,
I have a TI DM8148 EVM board REV C, the EZSDK5.05 SW package, and DVRRDK1.09 SW package.
EZSDK5.05, DVRRDK1.09 both use Linux2.6.37, however, there are some modifications between these two kernels.

When I use uImage of DVRRDK1.09 to boot up EVM board, this board can be given a DHCP IP from my office network, but uImage of EZSDK5.05 can’t. I try to build a DHCP Server on my local PC, let EZSDK5.05 and DVRRDK1.09 get DHCP IP from my local PC, both uImage can get DHCP IP. Any body can tell me what’s the problem ??

(One board with two version kernel, one kernel can get DHCP IP from my office network, the other one can’t. But both kernel can get DHCP IP from my local DHCP server.)

Thx ~
