A hardware switch that will jump between 2 wired networks

Does anyone know if this exists.
I am looking for an equivalent of a KVM switch for networks. I have 2 networks coming into a room I have a switch that needs to move back and forth from one network to the other. Currently when I need to switch I unplug the cable from network 1 and plug
in the cable from network 2. I would like something where I can just flip a switch and I switch networks.

I was afraid of that. Anyone have an idea how to accomplish this without pulling network cable to the location of the second wired network?

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

I get the impression that most of the users on older hardware experiences similar temperature issues on Lion for a long time now. Awaiting for confirmation from the original poster.
In the meantime I'm just cautious with regards to pushing the machine to such extreme temps, since something tells me such behaviour which includes monitor flickering and the likes is nothing but abnormal for any type of use...

Calendar app that will synch between iMac 10.6.8, iPad 2 and iPhone 5

I am looking for a calendar app that will synch my 3 devices (iMac 10.6.8, iPad 2 and iPhone 5). I tried upgrading my iMac to the latest version, whatever cat that is. I hated it ANd it didn't synch properly. Most events duplicated and some up to 5-6 times. I might have stuck it out and tried to figure out the replicating issue but I despised the entire interface to downgraded back to 10.6.8. I am thinking there has to be an app out there that will successfully synch calendars between these devices but from my search in the App Store, most seem to be geared to mobile devices only but I want to be able to see my events when I am at home on my iMac, too. Does anyone know of an independent app that will do this?

How do I make a wired connection to my Airport Extreme that will share the same network as any wireless connection to it?

Here's the set up.
I have a cable router into the house and then an Airport Extreme connected to it. Everything connects wirelessly to the Airport Extreme apart from one computer in the same room as it, which I wired into the AE with a cable (it's a gaming PC and has no wireless).
How can I get that wired machine to use the same network as all the other wireless devices? When I plug the cable into it, the gaming PC only picks up the network being created by the cable box which I don't use.

There is nothing stopping you connecting to the wireless computers if you have sharing turned on..
How can I get that wired machine to use the same network as all the other wireless devices? When I plug the cable into it, the gaming PC only picks up the network being created by the cable box which I don't use.
I don't quite follow this..
If the cable modem is a router.. the AE must be in bridge mode..
So all routing is handled by the cable modem router.. and the wireless clients will all be in the same IP range as the PC is.. please check that by opening the PC command window and type ipconfig /all
Then go to one of the wireless devices and check that it also has the same IP range.. eg,, 192.168.x.x and same router or gateway address eg 192.168.1.1 and same DNS.. which is the same as the router address..
Then in the command window of the PC use the command ping to see if the other devices respond.. ping it by name or by IPaddress.
If there is no response.. windows has decided it is in a public network.. and slammed up the firewalls.. make sure your network is set as home for location.. and make sure the firewalls .. you can have multiple if you have an internet security package are not blocking local network access.
Also remember PC and Mac in a network can take a bit of fiddling to see each other. But ping should always respond and in both directions.

Is there a neat way (or hardware solution) that will allow me to stream a DVD onto my new Retina display Macbook Pro?

am going to update my Macbook Pro for the new Retina model but the one thing I will miss is a DVD drive. I've ordered a Superdrive BUT my dilema is this...
Often my wife will be watching some dull reality show (Strictly Come Dancing or X Factor) and I would usually get my laptop, headphones and grab a DVD Box set (The Wire, Sopranos etc).
I could sit and watch happily (and eisily go back to wherever point I last stopped watching)
With the new Macbook I'm looking for the same easy solution. I don't want to sit with the superdrive on my lap, guess I can spend some time with Handbrake and rip all the DVD's to my new laptop (or a wireless storage device like this:http://www.seagate.com/external-hard-drives/portable-hard-drives/wireless/seagat e-satellite/
But this would be timeconsuming and I'm not sure if the ease of playback would be as good.
What I would really like is a DVD player that can just stream my DVD wirelessly to the laptop and I can control with the DVD player controls.
Does such a thing exist or can somebody suggest any alternative ideas?
Just to add, the main reason I chose this is that I often travel and the lighter, thinner design really appealed to me. I had considered a Mac Air in the past but it didn't have enough capacity or screen size for me when it was originally released.
I guess I will still have to transfer some DVD's anyway to be able to watch whilst travelling.

there is one actually use application called air playit, this is application has two parts the first one is the server part to install on any machine its available on Mac and windows you can configure it to stream from anything on the machine, the second part is the client you can install it on any IOS or android, the good thing about this application is you can use local network connection or Internet connection even you are outside still you can stream it

Is there a hardware router that will work with lookout?

I am looking for a good secure setup for protecting a Win2000 system running lookout 4.5. What is the best way to accomplish this?
Thanks David

David,
You can use any hardware router as long as it satisfies one of two requirements:
1) That there is no built-in firewall in the router
or
2) There is a firewall, but certain ports have been enabled. For more information about firewalls and networking Lookout, please see the developer's zone tutorial entitled "Networking Lookout or The LabVIEW DSC Module Across Firewalls"

How can I implement a backup 6500 that broadcasts the same OSPF networks?

I feel as though the answer for this is extremely simple, but my routing experience is very minimal. We have a 6500 switch that shares about 10 OSPF networks, which is behind out 7200 router; and we have a spare 6500 we would like to put into place at our second location as a failover. Can I add the same OSPF networks to this second 6500, or will this cause issues since two switches will be broadcasting the same network.
In the case that our core 6500 goes down, i would need the other 6500 to continue broadcasting these networks.

Yes, it's possible for two locations to advertize the same networks, but this implies that both locations can (normally) reach all the hosts on those networks (at either location). Also, if there's some kind of failure, some hosts (like one location's hosts) often can no longer be reached. That's normally ok, but what's normally not okay is for hosts on the same network to be partitioned.
Also, when you start to have networks across locations, sometimes there's requirements for hosts to logically migrate to the site that still is advertizing the host's network.
It can all get rather complicated depending on what exactly you're trying to accomplish.

Airport Extreme wired network can't assign IP address, but wireless works

*Problem details:*
We have three computers intermittently on, wired into the ethernet LAN managed by the Airport Extreme.
We have a few more computers that connect to the wireless network managed by the same Airport Extreme.
As far as I know, no fancy settings hijinks have been attempted. I manage the router, and I only plugged the Airport into the cable modem and connected all the wires to the computers. The WiFi setup went a similar way -- I just turned it on and it sorted itself out. This was eight months ago, mind you -- everything has been going quite well up until this weekend.
But! I got home from a trip this weekend to discover that all the machines that connected over the wired network could no longer get a connection to the internet. Any machine connected over the wireless network, however, was working just fine. Indeed, my macbook pros couldn't even see the Airport Extreme when I turned off their WiFi, connected them over Ethernet and opened the Airport Extreme configuration app!
The wired machines complain that they have a self-assigned IP address. Sometimes, after resetting everything, they look like everything's fine for a moment. Like I said, ordinarily my macbook pro does not even recognize the router over the wired network. However, after reverting to factory defaults and restarting the Airport, the laptop did see it (until a few minutes went by and it realized something was wrong).
I figured that renewing my DHCP lease would fix this problem, but it did not. Nor did turning off Passive FTP Mode (PASV) under Proxies in the Network configuration pane.
I have tried resetting the router to factory defaults, power cycling the modem and router in various configurations, etc. but nothing has worked. In addition, I have verified that connecting any machine to the ethernet directly from the modem will work, so the problem is definitely being introduced by the Airport Extreme.
So I guess my question is: what do I have to poke to return everything to normal? I'd like working wired and wireless networks again.
*Some last few details:*
The Airport is running 7.5.2, but downgrading to 7.4.2 produced no tangible difference.
I have an Ubee D3.0 modem. All lights are green and blinky except the DS light, which is solid amber (and it is green when the modem is wired directly to one of my computers -- it's only amber when connected to the Airport).
Some of the machines that can't connect to the wired network are PCs, so it's not just an OSX thing.
My roommate's XBOX 360 can connect to the internet over the wired port. It doesn't have WiFi, so I'm pretty sure there's no way it could be fooling me.
Thanks in advance for any advice you can muster.
EDIT FOR APOLOGIES:
I didn't realize I was posting this in the "Airport for Windows" section. While a Windows computer's connection is a concern, I would much rather get my Macs online and deal with that first. I can't figure out how to move the message myself.

*An update:*
Several days later, this issue seems to have fixed itself. I suspect there may have been Funny Business on my ISP's end (but then again, it's an ISP).

Disabling the integrated graphics card or updating any software they use that will aid the computer in switching between the two graphics chips.

So I couldn't activate Assassin's Creed 3 on bootcamp which I shuold have been able todo. I posted it on Ubistoft Support and This is what I got!
Hello ,
It looks like your DXDiag report is showing only an integrated graphics card. Being an Apple computer with an i7, it should have a dedicated video card as well. You may need to contact Apple support so they can help you either disable the integrated graphics card or update any software they use that will aid the computer in switching between the two graphics chips.
So I was wondering how I could disable the intergrated grahics card or update any software that will aid the ocmputer in switching between the two graphic chips.

The Early 2011 13-inch MacBook Pro has only got one graphic card, and this is the integrated card, Intel HD Graphics 3000.
Some games don't support this type of GPUs, and it looks like Assassin's Creed is one of them, so unfortunately, you can't run the game in this MacBook

Can I use the Time Capsule as a backup drive and wired network switch? I do not want to use the wireless part as I already have an ADSL 2 Wireless Router for that. Thanks.

Hi
I just went from PC to MAC. Have a MAC Mini and wanted to get a time capsule for backups. I would like to use it as a wired device instead of wireless. Would me connecting it to my router do the trick? Can I then use the LAN ports in the back of the capsule like I would a network switch? Can I just disable the wireless router part of the capsule as I already have an ADSL2+ Wireless Router.
Thanks

I wanted to run a cable upstairs from the switch downstairs so the Time capsule becomes my upstairs switch (as I only have Wireless upstairs at the moment. That will work right?
Cheers.
Yes, that is also fine.. ethernet being the cable you run.. !!
You still don't have to use a TC.. which is still a rather expensive box for the job.. an Airport Extreme would offer the same exactly minus hard disk for cheaper price and more than likely better lifespan.. TC with internal power supply run too hot.

Need help choosing optimal hardware for a laptop that will run AE CS5

BACKGROUND INFO (Questions listed below)
I need some help figuring out the best hardware configuration for a new laptop. I’m a student at a design school and I will be using the laptop to mainly run After Effects and to a lesser extent Photoshop and Illustrator. I don’t need to worry about 3D rendering software or Premier Pro. I am primarily interested in getting the best performance during editing. I am not looking for the best performance for final output. I would prefer to sacrifice final output times for better editing/interface performance.
I will be working with standard definition content and perhaps HD up to 720p on occasion. I do not need to operate in resolutions higher than 720p. My projects are generally animation and use many sources and many layers.
I’ve been reading up on optimal hardware configurations for CS5 but my understanding is still a little foggy and I would like to use this thread to figure out how to build the best machine for my budget. The budget is about $1400 to $1600 CANADIAN after tax.
I DON’T need help finding the laptop. I will search for it on my own. I just need to understand the best hardware to purchase within my budget.
I realize that it is probably impossible to buy the laptop I want with the hardware configuration I need “off the shelf”. Instead I will be looking for a good base model (~$900-$1100) and I will purchase the necessary hardware upgrades separately. I will not be purchasing a Mac.
Right now I’m thinking of a machine built something like this:
- 15”-16” screen (17” models are too big/heavy)
- Mid to high end i5 processor OR entry level i7 quad core
- 8GB RAM (I would go to 12GB, but it’s hard to find a 15”-16” laptop with 3 memory slots)
- SSD to replace HDD (However, if possible, I would like a laptop with dual HDD support or swap the optical drive for another HDD. If I had access to 2 drives, I would have and HDD/SSD combo).
- Medium/high end NVIDIA GPU to take advantage of OpenGL while editing.
QUESTIONS
1) Does the “Render Multiple Frames Simultaneously” option enhance general editing performance (applying filters, scrubbing through the timeline, reverting history states)? Or does it ONLY help speed up RAM previews and final output? Does it reduce the length of RAM previews?
1b) Is this option even necessary to enable on 64bit systems? (As far as I understand it was used to solve a problem where 32bit systems/software would only recognize 4GB of RAM per instance of AE).
1c) If I turn this option on to help with RAM previews, would I be hindering general editing performance in any way? Or does this option have basically zero drawbacks?
2) How come “Actual CPUs that will be used” will read 0 even if the sum total of RAM assigned to the CPUs plus the RAM reserved for other applications is less than the total available system RAM (on a 64bit system)? For example, I currently have 4GB RAM and 2 installed CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are used, even though the total RAM adds up to only 3.5GB.
CPU
3.) Considering the fact that I am more concerned with smooth performance while editing rather than final output speeds, would it be better to get a dual core i5 clocked around 2.5 or a quad core i7 clocked around 1.8?
4.) What is the difference between an i3 and an i5 processor even if they are clocked at the same speed? How does an i5 460M compare on the grand scheme of things?
RAM
6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If so, how should I be calculating optimal RAM based on # of cores. Should I also be counting threads, or just actual physical cores?
STORAGE/SWAP
7.) Should I replace the HDD with an SSD? I'm looking for snappy interface performance while editing. I would think that if the RAM fills up it would be best to have the SSD for scratch/cache.
8.) What performance benchmarks are most important when considering an SSD for After Effects? (4k writes? IOs per second? Max read/write?)
9.) I can afford the OCZ Vertex2 120GB SSD. Would this be a good choice if an SSD is recommended?
10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
GPU
10.) After Effects utilizes OpenGL to enhance editing performance. I will not really be using Premier Pro, so catering to the CUDA Mercury Engine is not a concern. Do high end gaming cards provide significant gains in OpenGL performance? Or do OpenGL performance gains taper off around the mid-range GPUs? (i.e. can you justify buying a high end GTX 260M graphics card for enhanced editing performance versus an "entry level" dedicated card like the 310M?)
11.) What hardware specs are most important when considering a GPU for editing performance in AE? (Memory size? # of Pixel shaders? Core speed? Shader speed?)
Thanks so much for any answers you can offer to these questions.

Please make sure that you've read through this page and what it points to.
> 1) Does the “Render Multiple Frames Simultaneously” option
enhance general editing performance (applying filters, scrubbing through
the timeline, reverting history states)? Or does it ONLY help speed up
RAM previews and final output? Does it reduce the length of RAM
previews?
It only increases rendering speed for RAM previews and rendering for final output. In After Effects CS5, it doesn't decrease the length of RAM previews. (In CS4, it does.)
1b) Is this option even necessary to enable on 64bit
systems? (As far as I understand it was used to solve a problem where
32bit systems/software would only recognize 4GB of RAM per instance of
AE).
You misunderstood. Yes, it's still relevant on 64-bit computers. Moreso, in a way. (I'd rather not spend my entire Sunday writing out detailed answers to satisfy idle curiosity, so I'm not going to give all the technical detail to that answer.)
> 1c) If I turn this option on to help with RAM previews,
would I be hindering general editing performance in any way? Or does
this option have basically zero drawbacks?
It takes a small but nonzero time for the background processes to start up when they need to be used and shut down when they're done. And as they sit waiting, they take up a little bit of memory. So, it's not exactly correct to say that there are no downsides to leaving it on. But it's close. I leave it on.
> 2) How come “Actual CPUs that will be used” will read 0 even
if the sum total of RAM assigned to the CPUs plus the RAM reserved for
other applications is less than the total available system RAM (on a
64bit system)? For example, I currently have 4GB RAM and 2 installed
CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per
CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are
used, even though the total RAM adds up to only 3.5GB.
4GB - 1.5GB for other software leaves 2.5 GB for After Effects.
If you have 1GB assigned per background CPU, then the foreground takes 1.2x that = 1.2GB. That leaves 1.3GB for background processes, which is enough for one background process. There's no point in starting only one background process to do rendering, so it doesn't bother. (Note: When background processes are rendering, the foreground process isn't rendering.)
> 3.) Considering the fact that I am more concerned with
smooth performance while editing rather than final output speeds, would
it be better to get a dual core i5 clocked around 2.5 or a quad core i7
clocked around 1.8?
Get the quad-core. That gives you a greater total number of cycles. And After Effects works very well with mutliple processors, even beyond Render Multiple Frames Simultaneously multiprocessing. An entirely unrelated sort of multiprocessing (multithreading) spreads work out to multiple processors.
> 6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If
so, how should I be calculating optimal RAM based on # of cores. Should
I also be counting threads, or just actual physical cores?
The optimum amount is the amount that you can cram into the computer. I'm not kidding. Spend your budget on RAM until you have 4GB installed per processor (and I'm counting the virtual processors due to hyperthreading). If you have a quad-core, that's 8 CPUs with hyperthreading, so the optimum amount of RAM installed is 32GB. You can work with less, but you did ask about optimum. For HD work (i.e., 1920 pixels across), you're OK with more like 3GB installed per CPU. That's what I have at home: 24GB in a quad-core. You're going to assign 2/3 or so of the RAM to After Effects, so 3GB installed per CPU is 2GB per core for HD work in After Effects.
> 10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
12GB of RAM. Because After Effects likes RAM. (If you're thinking of deliberatly using virtual memory to swap memory to the hard disk, don't. That's a performance killer.)
> 10.) After Effects utilizes OpenGL to enhance editing performance.
Not really. If you're on a limited budget, don't even think about the GPU until you've already got the most RAM, the fastest CPUs, the largest number of CPUs, two fast hard disks, and a couple of good monitors. Then, and only then, should you even consider getting soemthing beyond a non-stock graphics card. Yes, OpenGL can be used to accelerate some things, but that's only for the low-fidelity preview renderer. (Pardon the bluntness, but I want to make sure that you heed this.)

G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
We were in the process of installing 10.4 Tiger before placing it for sale.
The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
We have done the following during our troubleshooting:
- Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
- Remove RAM 1 stick at a time and reboot
- Replace RAM with RAM from another working Quicksilver
- Replace Video Card with one from another working Quicksilver
- Zap PRAM
- Reset CUDA switch
- Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
- Tried booting from the Macintosh Server G4 Software Restore CD
- Tried booting from Mac OS X Server CD
- Tried booting from AppleCare Protection Plan CD with TechTool
- Tried booting from Diskwarrior CD
- Tried booting from an external FireWire drive with a disk image of Tiger OS Install
- Tried booting with the hard drive disconnected
The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
I would look at the CD drive cables, etc, and see if another drive gives different results.
You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

Autoselection for a switch between wired and wireless network

Hello,
We currently have a VTC codec installed on a mobile cart that can connect via wireless or wired network. The cart has the Linksys WET610N Dual-Band Wireless-N gaming and video adapter bridge. If you want to go wireless you will have to unplug the CAT5 that goes into the walljack and plug in the cable from the bridge into the codec.
We need a 3-5 port switch. Port 1 will connect to the wireless bridge. Port 2 would be available to connect to a wall jack. Port 3 will connect to the codec.
We need the ability for the switch to autoselect port 1 and 2. If Port 2 is not connected (no link light), then Port 1 will be active. If Port 2 is active, Port 1 will be inactive.
I need to know how to configure the bridge and a network switch if this is scenerio is possible. Any help is appreciated.
Thanks,
Aaron

Well, I thought i had tried this before, but I followed another board's suggestion of turning of IGMP proxy and it is now working. I can see my iTunes server which is wired on my wireless devices.

NetworkManager - switching between wired and wireless

Hello!
I’ve set up a new laptop with Arch and now have a question concerning NetworkManager. Is it possible in NM to switch between wired and wireless connections like it is with Connman (https://wiki.archlinux.org/index.php/Co … d_wireless)?
So far it appears that NM only disables the wired connection when wireless is used but keeps the wireless alive when switching to wired.
I have already looked for a corresponding configuration but couldn’t find anything that helps.
Thanks in advance.

Easy Mode:
You can install the tlp-rdw package and edit the /etc/default/tlp configuration file which has an option that does that.
Hard Mode:
If you don't want to install a package and its dependencies, you can write your own script and put it in /etc/NetworkManager/dispatcher.d and have the NetworkManager dispatcher hook run the script (which is actually what tlp-rdw does but you don't have to install the tlp package as a dependency)
Note: tlp is a power manager and if you have any other power managers installed it might conflict with them so be wary of that.
Here is the wiki page on tlp https://wiki.archlinux.org/index.php/Tlp
