    Cisco, Ruckus, Meraki, Unifi, Aerohive...?

    You mentioned Ruckus, but no one else did. Ruckus has all the same management features as the larger companies out there, but they started a little smaller, so their controller is really easy to use. You can easily setup a network in as much time as it takes you to unbox all the parts. Ruckus...

    Windows file share credential prompt slow

    Scenario: Take a PC that is not a member of the domain, have it try to access a file share on a domain PC; eg start -> run -> \\domain_PC_ip_address The pc prompts for your domain username and password, you enter the credentials and login. However, that password prompt takes forever to...

    combining/teaming two ethernet sources on a switch

    I would not even attempt to do what you're proposing. I can't imagine anything but a big mess. You're far better off running some cat5 or purchasing faster wifi gear.

    Two-PERSON authentication

    Split the password in 1/2, give each half to one person. For more security, split a long password into 3 pieces and give 2 pieces each to 3 people. Then you can access the data with any 2 of the 3 people present.

    Traffic Compression?

    The applications you've heard about basically rely on the fact that in a client-server model, the same data is sent repeatedly across a WAN from a server to the clients. So you setup an appliance at each end of a dedicated link. The appliances keep track of the data and do a substitution...

    AC Access point or build-in wireless on consoles

    Faster for what? They both have 802.11N wireless. I don't know for sure, but lets assume it's only single mimo, so 150 Mbit, real life speed closer to 75 Mbit, depending on your house layout. Why do you need more than 75 Mbit? Unless you're on google fiber, your Internet connection is way...

    If you switch off NAT for cable internet router does it compromise security of router

    I'm reading the original question and comments and I think some core concepts here aren't being understood. In a typical home or small business with internet delivered via cable modem, the ISP hands you a network connection, normally Ethernet, and allocates you between one and five public IP...

    Looking for remote connection/tracking software for privileged laptop users

    You want Lojack for laptops to track the laptops and wipe them remotely if stolen. For remote troubleshooting, loginmein would work fine.

    Cable labeling strategy?

    Some companies have standards, but nothing else. We generally use different color cables for different networks; out of band management (ILO, DRAC, etc...) is yellow. Normal data is black, iSCSI network is blue, etc... If you move servers around a lot, you might just label each cable with...

    Wifi for 1500 person auditorium

    25 APs in a single room is insane. There is no way that's going to work. In the 2.4 Ghz band, you only have 3 non-overlapping channels. In 5 Ghz, 21, though there are assorted rules on that. You sounds like you're in over your head, I strongly recommend you hire a company to give you some...

    SMART data from HP Array Controller?

    I have an HP vmware esxi server with a smart array controller. The controller has generic SSDs attached. So I want to look at the SMART data to understand how much life is left on my SSDs. I can pull the disk from the system and gather the SMART stats, but everything seems to reset to...

    I need a voice getway

    So what I would suggest is to buy a voice/fax modem, I'm not sure if they're even made anymore. Actually, yes they are. http://www.trendnet.com/products/proddetail.asp?prod=150_TFM-560X&cat=51#prettyPhoto Then probably a virtual audio driver and RDP from work PC to home PC, yuo might be...

    Purposefully wrong IP address.

    And you're also taking a PC and plugging it into the public network, then your private network, back and forth? That sounds like a good way to get viruses unless you have firewalls on both networks.

    Blocking Websites Using a GPO

    Yeah, I would love to do that, but they don't want to spend any money to do this. Then it must not be important to them. Seriously though, there is no part of windows which is intended to do what they want. In any case, if you do manage to allow/block various web sites, people will be able to...

    Linksys E4200....cannot connect to default GW

    disconnect everything from the router except your laptop. Use a wired connection, not wireless. Try it out that way. If working, plug in one additional connection at a time.

    Blocking Websites Using a GPO

    Let me save you some trouble. Buy a web filtering product. Barracuda makes one that's decent. You can do something crazy with the hosts file on a PC to block access to some web sites, but it'll be a messy hack at best. If you manage to get it to work, you'll get another request to block/allow...

    Global iSCSI Target

    iSCSI is block data. Think of an iSCSI connection as being the same as a SATA cable to a hard drive. Unless specifically designed for it, the file system does not support multiple concurrent connections. So what you really want to do is make a normal network share and connect to it from...

    Confused on bulk cat5e cable diameter

    One more note, unless you have a very specific need for cable lengths, you will always be better off just buying cables. 99% of the time I have issues with cabling, it comes down to the worksmanship of how the cable was terminated. And unless your time is worth nothing, pre-made cables...

    Need help / advice wiring home for network

    Probably not overkill. Wireless is great, but wired is always faster. But don't blindly install wiring. Make sure you know what you're going to use it for. Live in the house for a couple months before doing the project. As a new homeowner, you're going to have plenty of expenses anyway...

    'War Games' mainframe's speed?

    A little higher, yes.... Lets assume that the WOPR was the fastest computer in the world, that would be the Cray X-MP, with a top speed of 800 Mega FLOPS. The current fastest computer in the world is the CRAY XK7, with peak performance of about 27 Peta FLOPS. So our modern computer is...

    Generic SSD in HP Generation 8 server

    So we're looking at building a server farm using HP DL385 Gen8 servers. We want to use SSDs, but the ones from HP are at least double the cost of other SSDs. Anyone put a generic Intel, OCZ, etc... SSD in an HP gen8 server?

    POE injector with 20+ ports, recommendations?

    You might have problems with a midspan that isn't rated for Gig, if you try and use Gig devices. Do it the right way. Get a proper POE switch or get a gig capable midspan. I've used powersdine, though I don't know how their stuff is now that they've been bought. For single port injectors...

    350 feet of cable from demarc

    Run the fiber from the demark. You'll have to get someone to do it, as you cannot buy a pre-terminated fiber patch cord that long. It's likely to be expensive. But no one ever regrets doing things the right way.

    Server, VPN, Remote Desktop setup help

    So you've got 2 sites, connected to each other via a VPN. You want to place a print server at one site and use it to print to a printer at the other site. Bad idea. Every print job will go once to the print server, then back down from the server to the printer. If server is in site A, and...

    Looking for a good wireless AP

    Linux driver source... Now unless I'm quite mistaken, that's going to be a problem. Wireless is a software driven radio. The drivers have a lot more intelligence in them than a wired NIC. As such, the companies who write the wireless drivers aren't all about giving away their code. You...

    Any idea's on this ActiveDirectory Login Issue

    Windows has a machine account, similar to a user account. The machine account has a password and that password can expire. If the computer isn't on the domain often enough, that machine account password expires, and the computer is essentially disconnected from the domain. That sounds like...

    Password Security and Storage

    The bigger issue now is people using identical passwords on multiple sites. Make sure that if you're using a password manager, you take the time to change all those passwords to random garbage. Likewise, secret questions (name of your first pet, etc...) are easily discoverable via facebook...

    Separate internet and intranet.

    Yes, disabling or changing the metric on the server network interface is what you want. But, by doing what you're doing, you're connecting those 2 networks by way of your PC. I assume they are separate for a reason. You don't want to be infecting the server network with viruses from the...

    Question about POE and 12v devices

    Yep. if you look at the spec sheets for those cameras, they list power source as "DC12V/AC24V, PoE(802.3af)" So you can use standard POE, or a 12VDC or 24VAC power supply.

    54 mbps on a 300mbps setup?

    Just use the windows software to control wireless, don't bother with the 3rd party stuff unless you have a specific need. Make sure your AP is set to N speeds, and that should do it.

    Question about POE and 12v devices

    It's quite a bit more complicated than simply measuring impedance, it's enough to know that there is a handshake between the power device and the endoint that occurs before any power is actually delivered. The voltage never changes, just the wattage. Anything that uses power will heat up...

    Question about POE and 12v devices

    There is some confusion here. When people use the term POE, they mean 802.3af POE, which is a standard. A device supports it or it doesn't. When using POE, the power source (switch or injector) will negotiate with the endpoint device to determine how much power is needed and other controls...

    Something weird with FiOS

    Yes, Verizon uses the 10 network as part of their network. It's even reachable from your FIOS connected device. But normally that doesn't matter. Your firewall will NAT your internal addresses to the public IP they give you and you're all set. If you really want to be proper about it, you...
