Networking via cross-over ethernet

I have two PCs both running Windows 7 Pro 64 bit. Both are fully updated.
One connects via wireless adapter to a router at the other end of my house (not practical to connect it via ethernet).
The router gets my ISP signal and is my Internet access point.
The other PC is in the same room but has no wireless adapter (I know I could just get one, but that is not what I want to do here).
The two PCs are close enough that I can easily connect them directly to each other with an ethernet cable.
I tried a regular cable but connecting gave me problems so I used a cross-over cable to connect them.
My original intent was to be able file access & sharing of the (let's call it guest PC) and the one with the wireless internet access (let's call it the host).
When I rebooted both I was able to open the explorer and see the host computer from the guest and vice versa on the Network list. I allowed file sharing and everything looked great.
I mapped the user and file locations from the guest that I wanted in the host PC as a network drive on the host.
Since I wasn't regularly using the guest, it went to sleep and I could not re-establish the mapped network drives nor the shared file connection. That was a pain, so I set out on another option.
I set up a Home network in the guest PC that is now accessing the Internet.
OK, I'm not exactly sure how I did that. I kept creating unidentified public networks and finally was able to create a private one on the guest that connects (I'm not sure if it was by sharing or merging) to the Internet. It has to be somehow shared
because (as I mentioned above) the guest has no wireless adapter and no other way to get Internet except by sharing the host PC's wireless access.
Well, the drives that I had mapped before setting up the Internet sharing suddenly work again fine.
But, AND HERE'S MY CURRENT PROBLEM, I cannot see the guest computer from the host in the explorer (or the other way either).
I tried then to just join the host computer's HomeGroup, but I can't. I can't join a HomeGroup created on the guest either.
I'd like to be able to view and share my files across both the host and guest.
I'd even like to be able to remote access the guest desktop from the host. (I know I can do that with LogMeIn, TeamViewer, VNC, and other programs).
I also know I can share files using Hamachi (but it does not give remote desktop control so I can't run programs).
Can anybody help me on this? Or is it impossible to use a cross-over ethernet connection between two PCs and have them both share files and be visible either browsing on the Network or in a HomeGroup?

Thanks, I have never solved this. I did check your links. At one point at least I was able to share my wireless connection, but I don't know how I did it and now I have even lost that trying to fix the fact that I could not actually network the two PCs.
Again, both running Windows 7. One has wireless adapter & connects to Internet through router - no problem there.
Second PC has no wireless adapter. I wanted to use cross over ethernet cable to connect it directly to the one that has Internet access. The idea was twofold: first, setting up a peer to peer local network with both PCs on it so I could directly open &
share files from one to the other. I fiddled so much that now I'm getting a message that the PC without the WiFi adapter does not have a valid IP address.
My second (and actually more important goal) was to allow the PC without the WiFi adapter to share the other PC's Internet connection. I did something with the merging option that made it work but I don't know for the life of me what it was. I kept having
trouble with the new network defaulting to Public and I could not change it to Private. That gave me all kinds of problems trying to create and join a HomeGroup. I could create them in each PC but neither could join the other's created HomeGroup.
Now I'm back to square one, or even worse since I can't get either of my goals solved. If it's impossible to network them P2P I'd at least like to share the Internet connection using the cross-over cable as I had it for a few days.

Mac pro - powerbook g4 - networking with cross-over cable

I connect my powerbook to the Mac pro with a cross-over cable.
Personal file sharing is on both computers (both Mac osx 10.4.8)
Question 1:
While most of the time I can make the connection work I still don't understand the logic behind it.
Sometimes I connect and the connection works immediately, on other occasion I have to restart one of the macs or both to make it work.
Is there another solution then restarting?
Please enlight me on the subject.
Question 2:
My Macpro is connected to the internet (to a ethernet-router up the line, I can not pull another cable from the router because all the ports are busy).
My powerbook is connected to the Macpro with the cross-over cable.
Can I access the internet on my powerbook through the cross-over cable. I already tried the Internet Sharing on/off thing but I couldn't make it work.
Thank you all for sharing your knowledge on the subject.

Hello Eugene,
Just a quick note to let you know you and others know that you do not need a cross-over Ethernet cable to connect your Mac Pro to another device. The idea of using a cross-over cable is a hold over from bygone days of Ethernet ports and products that either were before the auto-mdix or just did not implement them to save cost. Auto mdix Ethernet ports (which the Mac Pro, and every current Mac computer has) are able to detect the type of cabling/connection, and auto configure the Ethernet port for the proper connection. This mean you can use a regular Ethernet patch cable and not be concerned if it is a straight thru or cross-over style.
As for sharing your internet connection using your Mac Pro, yes, it can be done, and the capability is included with OS X. You can find step by step instructions by accessing the Help menu in the finder and entering "sharing Internet" (without the quotes).
However, I would suggest you just buy an inexpensive Ethernet Switch, to use to expand the number of ports available from your router, and then run a line to your other computer.

Cross over ethernet cables?

When connecting a G4 power mac to Mac Pro, is a cross over ethernet cable still needed?
Thanks

Hi-
For your MDD?
No.
Any G4 tower later than a Sawtooth doesn't need a crossover cable.

Extending Wireless Network and Bridging Over Ethernet

Have a TimeCapsule and Airport Basestation at home. Both are currently connected over wireless using the "Extend Wireless Network" feature.
On each of the devices have several laptops, mac minis etc. connected over Ethernet (since wireless insufficient for our high speed data transfers etc.)... Trouble we are having is the speed/connection between both the TC and the AP, so considering to connect them both over Ethernet to improve.
Question is once they are connected over Ethernet, what happens to the "Extend Wireless Network", how does the TC and AP know to either use the wireless or the Ethernet to connect with each other? Does one take precedence over the other?
We want to keep them both on Ethernet and Wireless bridge ideally, so that at opposite ends the wireless network is extended for our iPhones and iPads and all devices connected on Ethernet benefit the speed boost over Ethernet, but just not sure how it will behave, and not sure how to test this scenario....
So asking here instead
Thanks!

It sounds like you might want to configure your base stations into a "roaming network".

IMac G5 no longer prints to laser printer over ethernet network

I have a small office with 6 iMacs networked via ethernet with a Netgear Router. Printers are connected to one machine and people send to print over the network.
3 iMacs are G5. 3 are Intel. All run OS X 10.5.8.
A month ago one of the G5 iMacs stopped being able to print to a Brother laser printer (which is connected by USB to an Intel iMac). I believe this happened after we downloaded a periodic Apple update. About 2 weeks ago a second G5 iMac developed the same problem. The 1st G5 iMac still prints fine to an inkjet printer connected directly to it by USB.
We have tried re-loading drivers, but no improvement.
Any suggestions as to how we can resolve this?

Hi DaddyPaycheck
The iMacs that can't print can see the printer. We have deleted and re-installed via the printer system prefs too. There weird thing is that you can select the printer and send to print, but for some reason the printer then automatically pauses and you can't resume it. The file is listed by the status is 'stopped'. When you open the printer queue on the Intel iMac that the laser printer is connected to, no print file shows up at all...
We also ran the network diagnostic that you can do when in printer system prefs and that reported that "the G5 iMac could connect to the internet, but not the Server "brother HL 4040CN series-1@ben's-iMac-2.ipp.tcp.local" "
Hope there's a clue in there somewhere...

Printing to the network via USB Ethernet

I have a pair of MacBook Air's that are using the USB Ethernet adapter to connect to the local ethernet (wireless is not an option, all workstations must be wired while in-house.)
The problem I run into is that both of these MBA's will loose their connectivity to the printers, or their ability to see bonjour devices at all, or Appletalk devices. In particular, I've installed a set of OkiData printers on the network which support both Bonjour & Appletalk. When I setup the printers as IP printers, they seem to work fine. However, if they, or any other printer, is connected as a Bonjour device, eventually the MBA stops recognizing/seeing/looking up Bonjour items on the network.
Any thoughts on why this is or how to correct it would be really useful, especially since some day the users might like to do some bonjour-based file sharing.
Thanks!

I have a client with the exact same problem. No bonjour when attached via USB ethernet (Apple's own) SOMETIMES. However, I've noticed that if she unplugs and tries the other usb slot, it seems to work (immediately, no reboot). I've actually only told her to do this over the phone, but it has worked at least twice.
One problem here is that the printers are NOT accessible via bonjour over WLAN, since the WLAN is at least 2 different C class networks.
The other is that due to the setup of the printers and crap drivers from Ricoh, using personalized printer queues only works over Bonjour and not TCP. Thus, only USB ethernet can be used for printing. It would be very interesting to hear if changing usb ports might help in your case as well. This particular client has a late 2010 MBA 4G/128G, but at the same department there are at least 7 MBAs where no-one has had the same problem. Either that, or they had it but never told me.

Mac Pro no longer connects to network via ethernet.

Since coing back from Thanksgiving break and my Mac Pro 1,1 will no longer connect to my router through via ethernet. This means I can neither connect to internet nor connect to devices like my laptop and Apple TV. Strangely, I can still connect to my Mac Pro from these devices to share screen, play audio/video through iTunes, etc. In Network Settings, I still have a green dot, and I still get an IP address assigned (though I usually use a fixed IP). If I go into my router (Netgear WNDR4000), the router tells me that the Mac Pro 1,1 is connected to the network.
I already have tried the following solutions:
· Restarting router, modem, and computer
· Making a new location in Network Settings
· Trying different ethernet ports
Please Help!

Your local LAN runs through your router.
All your ethernet ports, and your modem and router, should be behind and filtered from excess current. That means a UPS generally. And run input line thru UPS (coax) first, then run RJ45 back through UPS again (there can still be excess surge or current on the line).
Modems and routers can be compromised by surge outage or storm. So can ethernet ports.
You have two ethernet ports and you tried with both also.
What you did not do that I would have added is SMC Reset / Reset NVRAM/PRAM.
This is what I have had for the last year, very nice and stronger signals thruout the house.

Choosing the Right Network Protocol for CRIO 9024 to PXI over Ethernet

We are in the design phase of setting up a CRIO 9024 Embedded Controller to send data captured to a PXIe-8105 Controller over ethernet. The data will be be 2D arrays of double precision. This data will need to be sent to the pxi at the end of each test step. Each step will have different number of channels and sample rates.
For example, Test Step 1 will have 5 channels of Analog inputs that will be sampled at 100,000 KHz for 1 second. This data will be coming from the CRIO FPGA. The data will get post processed by the CRIO 9024 and analyzed for pass or fail metrics. Then, the CRIO controller will send the 2D Array of Data (500,000 data points 5 X 100,000) and the results of all the metrics (a 1D array) to the PXI.
The connection to the PXI will be using Ethernet.
Keep in mind that the PXI will also have to send the CRIO some values to tell the CRIO when to start the test and when the test sequence is complete.
I was thinking TCP/IP would work best because of the 2 way communication needed. But then I was looking at Network Streaming or even using Shared Variables.
If anyone has any ideas or suggestions please please post them.

Solved!
Go to Solution.

Hi,
You could use either. Whichever you are more comfortable with really. The STM method will have slightly less overhead over my XML style of tagging the data but it will be very little given the data size. Probably go with STM as it just has most of the work done for you.
In terms of data size the way you should normally transfer data like this is to flatten to string. If you convert to a string of human readable numbers you will either lose precision, increase size or both. Given that, the string after being flattened will be the same size as the original array anyway so quick calculation based on your previous post 500,000 doubles (8 bytes) is 4 miB (3.8MB)

Connect MacBook to wifi network via Ethernet

I am looking for a way to connect my MacBook to my wifi network via my Ethernet port. I'm not having any trouble with the wifi but am looking at getting an apple tv and wish to be able to use wolan. As far as I know, wowlan is only available using the apple airport routers. Is there something I can get that plugs into my Ethernet port on my MacBook, connects to the wifi network and lets my MacBook treat it as a wired connection so I can use wolan? I assume something like this would. E cheaper than buying an apple router that supports wowlan...?
Also, how do I make sure that my current router actually supports wolan?
Thanks.

We assume that you are trying to configure the AirPort Express to "join" your wireless network. In order to do so, you must enter in the wireless network name, exact type of security and password that your network is using.
Mistakes are often made with the security settings because different manufacturers use different nomenclature to mean the same thing. For example
WPA2 Personal on Apple = WPA2-PSK-AES on other wireless routers
or
WPA/WPA2 Personal on Apple = WPA-PSK-TKIP on other wireless routers
Can you dig a bit deeper into your settings on your router to find out whether you are using AES or TKIP? Once you find that info, you should be able to match up the correct setting on the AirPort Express during the configuration.
Don't be fooled by the the message that you see when you click Update during the configuration process. The message states something to the effect that the settings have been stored successfully on the AirPort Express. What it doe not tell you is whether the settings that were stored are the correct settings.
You will know that you have the correct settings when you see a green light on the AirPort Express 40-45 seconds after you click the Update button.

Apple TV to PC. Cross-over cable or Ethernet?

My apple TV will plug directly into the pc with iTunes. Do I need a Cross-over cable or an Ethernet Cable? And What is the difference? Also How would I do this? Thanks in advance!

I got it in April this year... If I have no internet where I am using it, how do I authenticate it to play? Here I have no internet BUT I have no HDTV here... My house has no Internet but it does have an HDTV! Do I need an HDTV to connect it to iTunes to authenticate it? Or can I use my existing Dial-Up connection to do it.. By using my dial-up connection I mean like Connect it to my laptop, and then connecting my laptop to my dial up connection and opening iTunes and do it like that... Would that work?

Problem using Express over Ethernet via Solwise Gigabit Homeplug

I am hoping someone can help me here.
Similar problem with Tandie (http://discussions.apple.com/thread.jspa?messageID=12175903&#12175903). I have a Vista PC which has no problem at all to connect to my Express over ethernet. I use my Express to "Create new wireless" network and stream my itunes over ethernet, which works well if I have a cable connected to the Express to my network where my Vista PC is connected.
However, when I take my Express to another room and connect it to a Solwise Gigabit Homeplug and my other homeplug connects to my network I then seem to have problems. The homeplug works perfectly with my PS3, but my Express after about 2 hours itunes and Airport Utility is unable to find it. I can however ping the Express, but that is it.
Here's how I configured the AX:
Wireless Mode = Create a wireless network
Wireless Network Name = unique name different to my Wireless BT Hub
Radio Mode = 802.11n (802.11b/g compatible)
Channel = Automatic
Click the Internet icon
Connect Using = Ethernet
Connection Sharing = Share a public IP address
AX Firmware ver: 7.4.2

Welcome to the discussions, Charles266!

Connection Sharing = Share a public IP address
This would be the correct setting if your AirPort Express is connected directly to a simple modem (a simple modem has only 1 ethernet port)
If you have the Express connected back to another router (it will have 3-4 ethernet ports), then the correct setting for Connection Sharing would be "Off (Bridge Mode)"
I can't say if this will solve your problem. If you continue to have issues, then test using an ethernet cable from the Express back to your main router. If this works well, then one or both of the powerline products is suspect.

HT4259 how to configure extended network via ethernet

how to configure an extended network via ethernet

I assume that the Express is new, so that it still has the factory default settings.
Connect an Ethernet cable from one of the LAN <-> ports on the AirPort Extreme to the WAN "O" port on the AirPort Express
Power up the Extreme and Express if they are not already powered up
Open Macintosh HD > Applications > Utiltities > AirPort Utility
Click on the tab in the upper left hand corner of the window that reads Other AirPort Base Stations (1)
Click on the AirPort Express xxxxxx
Wait a minute or two while AirPort Utility analyzes the network and then announces that the Express will be configured to extend your network
Enter a name for the AirPort Express and click Next
Wait 2-3 minutes while AirPort Utility configures the Express and the Express restarts
When you see the message that setup is complete, click Done
That's it.

I CANNOT PRINT FROM MY IPHONE 4 TO MY BROTHER 8890DW PRINTER WHICH IS CONNECTED TO MY TIME CAPSULE/NETWORK VIA ETHERNET CABLE???

Why can’t I print from my iPhone 4 to my brother 8890dw printer which is connected to my time capsule/network via ethernet cable??? My iPhone does not even locate my printer,even though I have no problem printing from my Mac to the same printer.

Typing in all caps indicates shouting, is considered rude and is difficult to read. Many simply do not read such posts.
You would need an airprint enabled printer or an app that proides printing function.

Hello, I'm trying to connect my new TiVo XL4 box to my home network via an ethernet cable connection to my Airport Express but the TiVo box is not seeing the network. I have a green light emanating from the Airport Express so it is connected. Plz advise.

Hello, I'm trying to connect my new TiVo XL4 box to my home network via an ethernet cable connection to my Airport Express but the TiVo box is not seeing the network. I have a green light emanating from the Airport Express so it is connected. Please advise.

If you have not already done so, I suggest that you temporarily disconnect the Ethernet cable from the AirPort Express that goes to the Tivo box.
Instead, turn off the wireless on a laptop and connect the laptop to the Ethernet port on the Express. See if you can get an Internet connection on the laptop.
If you still cannot get an Internet connection on the laptop, try another Ethernet cable that you know is working correctly.
Post back on your results.
