• Servers behind load balancer

  - by Tom

  We have a CISCO hardware load balancer with two web servers behind it. We'd like to force some URLs to only be served by one of the machines. Firstly, is the job of the load balancer? or would a better approach be create a subdomain such as http://assets.example.com which would be automatically be routed to one of the servers?

• Simple switch ports state monitoring tool

  - by Florent Courtay

  My users keep unplugging our meeting rooms computers network connection. As i can't check the computers every time a meeting ends, i'd like to find a tool, preferably running on windows, that can monitor some cisco switch ports state, and every time a cable is being unplugged, send me an email. I know that some monitoring solutions can do that already, but i wonder if something simplier (and preferably cheap / free of course !) exists.

• Default Critique branch office setup: VPNTunnel->HQ, subnets for VOIP/PC, + several Q's

  - by CHickenTaragon

  We're setting up a new branch office. * ~10 users. * Each user has a VOIP phone provided by a hosted solution. * Users need access to resources on HQ (located in another state), so setting up VPN tunnel * HQ only supports certain Cisco/Juniper devices. VOIP provider only supports SonicWall, so current plan is to have two routers w/ separate subnets for VOIP vs. PC traffic. * PC's will plug into pass-thru Ethernet jacks on the VOIP phones, but the phones vs. PC's will point to different subnets. * Cable Modem is 50Mbps / 5Mbps DOCSIS 3.0 business line w/ 5 static IP's. * Each of the 2 subnets will map to one of the 5 public IP's. * May or may not also need to support a VPN tunnel with a second branch office because of a file server they have there that some in the new office use. I'm pushing to have them move the files to a server on the HQ's network so we don't have to worry about setting up an additional tunnel. Questions: Do you foresee any issues with the below set-up? Router recommendations by HQ IT staff: Cisco Router 2811, or Juniper SSG5 or SSG20. Any recommendations about these routers? We need Wi-Fi too – looks like the above routers have models that support this, any reason not to use this? Users need to be able to work from home. If so, how is authentication handled? Right now we use AD credentials for the HQ's domain, but we currently don't plan to have an AD system in the new location since it's only 10 users. We can't tie the authentication system from the new location's router to the AD system of the HQ. All the PC's that will be in the new location are currently in the existing office that is closing down, and are already joined to the domain of the HQ. Please confirm: this + the VPN tunnel will be sufficient for them to connect to authenticated resources on the HQ's network from the new location, correct? Mainly SQL servers and file servers, and a few remote desktop sessions. I'm sure I'll have some more questions, but can't think of them right now.

• lightweight access point?

  - by Joelio

  Im moving from an all in one to a router + access point. In doing googling and reasearch and talking to friends I ended up with router - cisco rv016 wifi access point - airnet 1142 lightweight access point. (lap1142n) In trying to set all this up and reading I think I bought the wrong access point. It seems I need a wireless controller? Can someone confirm that I should not have bought the lightweight one?

• pull bandwidth from wireless WAN into local LAN

  - by cortical

  We have a local network (A) of about 50 computers connected via gigabit ethernet. We get a connection to the internet using two broadband connections to a backbone and distribute the bandwidth across the 50 computers using a CISCO 1811 router, but the bandwidth is not enough for everybody. There is a campus wide wireless network(B) that has very high bandwidth, is there a device or way to setup multiple individual connections to network B and supply the bandwidth to our network A?

• NetApp and Hyper-V 2012 best practice/whitepapers?

  - by grimstoner

  We've recently acquired a NetApp/Cisco UCS solution, and I'd like to gather some background knowledge as to the best practices when setting up Hyper-V 2012 on such a solution. There is an upcoming seminar (in the Netherlands, http://www.realdolmen.com/nl/MSHyper-v-2012_NetApp), but it's in Dutch, and a couple of weeks away... Does anyone have some whitepapers/documentation about such a setup, or hasn't it been done before?

• x86 Router Benchmarks?

  - by Kevin

  I have grow to prefer x86 based router OS's like Vyatta and pfSense over their competitors Cisco and Juniper (Well, I never really used Juniper, but still.). However, they feel "fake" to me, like "Frankenstein" routers. I think my greatest worry is that I am missing out on something by not using the main contenders. Are there any benchmarks out there that compare the main metrics (throuput, etc.) of x86 router operating systems to their proprietary counterparts?

• Is it possible to copy recordings off of a DVR box hard drive?

  - by bdr9

  My cable TV company gives me a Cisco Explorer 8640HDC DVR box that can record shows from TV. I know that it contains a hard drive to save the shows on. What format and file system are used to store the videos on the hard drive? I have looked at the documentation for this DVR box and there is no technical information about the manner in which recordings are stored. Is it possible to connect the hard drive to a computer and extract the recordings from it?

• iPhone CoreData join

  - by Ken

  Hi guys, long time reader, first time poster. (A link to this schema is located here) http://www.weeshsoft.com/pix/DatabasePic.jpg I'm trying to get all LanguageEntries from a database for a given category.categoryName and languageset.languageSetName e.g. NSFetchRequest* fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"LanguageEntry" inManagedObjectContext:del.managedObjectContext]; [fetchRequest setEntity:entity]; NSString* predicateString = [NSString stringWithFormat:@"Category.categoryName = %@ AND LanguageSet.languageSetName = %@", @"Food", @"English####Spanish"]; fetchRequest.predicate = [NSPredicate predicateWithFormat:predicateString]; NSError *error = nil; NSArray* objects = [del.managedObjectContext executeFetchRequest:fetchRequest error:&error]; This always returns 0 objects. If I set the predicate string to match on one relationship (e.g. Category.categoryName = Food or languageSet.languageSetName = English####Spanish) it will return data. This is baffling, can anyone shed some light? -Ken

• Custom Live CD using UCK

  - by phifer2088

  I am trying to create a custom live iso that I can place onto thumb drives for the purpose of using putty to program Cisco switches and routers. I have ubuntu 14.04 LTS installed on a laptop and also installed UCK. I used the desktop image for 14.04 and created a custom ISO. I was able to run terminal and install the putty application and add a new user. I added the new user to the dialout group so they could then access the serial port. I am not exactly where I want to be yet, but it is a start. I have loaded the ISO to a USB drive using netbootin, but it will not boot into the live cd for me to test that everything works the way I need in the image. Is this because of the image I used? Any help would be great. Thank you.

  Blackberry OS 7.1 ouvre BBM aux développeurs Pour « créer de la viralité» autour de leurs applications, des API pour le NFC Research In Motion ne va pas bien financièrement, mais RIM n'est pas mort pour autant. L'annonce de la version 7.1 de son BlackBerry OS montre en effet que le canadien est toujours prêt à se battre. Comment ? En étant toujours une référence pour les professionnels (support de tout type de messagerie, de protocoles et d'outils ? d'Exchange à SAP en passant par Lync de Microsoft ou les technologies de Cisco) et en donnant de nouveaux outils aux développeurs.

• Database vs Networking

  - by user16258

  I have completed my diploma in (IT) and now pursuing degree, i am in last semester of my B.E(I.T). I want to do specialization either in Database(oracle) or in Networking(cisco). Which one of two will be in more demand in near future, i know it's all about interest but still i would like to know your opinion. Most of people say that a network engineer is never paid as better as a programmer or a DBA, and few says they do get paid well. What would be the scope if i clear my CCNA and CCNP exams, or either OCA & OCP exams, what would be more rewarding. Also i have read somewhere that most of the task of DBA will be automated so in future demand of a DBA will reduce. I would also like to hear from Network engineers what's the scenario out there in India. Thanks
