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.

Two ACS4.0 box using win- can connect with cross over cable

Hi
we have 2 ACS4.0 box, internal replication is happening between ACS1(prim) to ACS2(sec) but not ACS2 to ACS1 why?
Also I need 1 suggesion, whether we can connect 2 ACS boxes through cross cable for sync.
At present it is connected with 2 diff cores(ACS1 to core 1 & ACS2 to core2) and cores are interconnected.
What is the normal practice.
Regards
Naga

Hi Naga,
The purpose of Replication in ACS is for the Primary Server to overwrite the secondary server's settings that you have chosen.
This is by design Replication is meant to be one way and not bi-directional.
The Cisco Secure ACS Solution Engine supports the operation of only one Ethernet connector at a time. Concurrent operation of both Ethernet connectors is not supported."
To get redundancy with any ACS - you need replication setup with TWO ACS, it is not
possible to setup a NIC failover in the same chasis.

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 (First Generation) problem with 1TB Seagate Barracuda

Hi Macianer,
I have a first generation Mac Pro which was sold with max. 750GB Hard drives for each bay. At this time I am grabbing for straws and maybe someone has any info on this problem.
I purchased 4 x 1TB Seagate Barracuda hard drives ( Model: ST31000340AS / Firmware: SD15 ), did a regular format after I purchased them ( GUID Partition Table, Journaled HFS+ File System). I am using 2 of them internally (they get quite hot and i didn't want to put all 4 of them in there) and two of them externally (backup purposes). The other two internal bays are covered by 2x 500GB Barracuda drives.
I put all four 1 TB hard drived through a 1 week stress test to make sure I am not dealing with bad apples. So far this practice served me well.
Now 2 weeks later one completely crashed (internal boot drive). It sounded to spin up alright but was not accessible at all. I went to BestBuy and GeekSquad said this drive is crashed and I returned it.
Since I had a backup I didn't worry too much. I put the back up hard drive in as the new boot drive (since it was a SuperDuper duplicat) it worked like a charm. Now the second hard drive starts temporarily freezing the system for 2-4 minutes and seems to get stuck showing the great colored ball of doom. After the freeze it continues to operate normal again and I am able to continue my work.
I ran the Disk Utility and I got the following message:
INVALID KEY LENGTH
VOLUME CHECK FAILED.
ERROR: FILESYSTEM VERIFY OR REPAIR FAILED.
It just seems weird, I never had problems with hard drives and now I get these problems with 3-4 week old hard drives.
I was in a chat with seagate support. First question to trouble shoot: Do you have access to a PC. My answer was no since Microsoft Vista I donated all of them to the Salvation Army. He asked if I formatted the hard drives low level and MBR with HFS+. I said since I do not have access to PC nor do I plan on using my hard drives for PC I formatted it regular with GUID and HFS+. I asked if there is any history of these drives that would help explain my experience. I was hoping for a recall or something of that sort or something that a firmware upgrade would remedy.
I guess my question is, is the first generation Mac Pro, even though it seems to format and run them fine, not able to handle 1TB hard drives on a daily basis. Or am I dealing with hard drive problems? The Seagate guy didn't seem to be of any help.
Any help is appreciated or even pointers that would help me in finding the problem.
Cheers,

Excellent questions, I too am looking at SSD.
Some things I know about SSD:
1. Intel recently released new firmware for their SSD drives to improve long term performance including Trim/Garbage collection.
2. SSD drives can be setup as SLC or MLC - SLC is faster read 2X, write 4X over MLC, however SLC is smaller capacity. SLC also has a longer life span.
3. Intel plans to have an 320GB X25-M (MLC) and a 128GB X25-E (SLC) out soon.
OSX does not fully support Trim and I'm not aware of any 3rd party software for OSX that helps in the garbage collection area. Diskeeper 2010 for Windows 7 provides full support for all variants of SSD, but nothing on the Mac side.
I'm probably going to wait for 2010 to see what comes out, SSD appears to be good news, but it still also seems to have issues. Given the cost of these drivers and the frequent firmware updates, a wait and see is my choice.
I've thought about going with a SAS RAID controller and 15K RAID drivers, but the cost/performance ratio comes out about the same and the 15K drives are noisey and power hungry but they're a "known" entity.

12 core Mac Pro does not improve render time over iMac quad core

I'm rendering the same composition independently on two computers and they are basically rendering at the same rate, which is slightly better than 1 frame per second.
The project settings and preferences are identical in each instance (with the exception of memory and multiprocessing, which I have experimented with ad nauseum). The composition includes no motion blur, no effects, just a couple of layers of chroma keyed .mov files (using keylight 2.0) and some still images. Neither machine is running any other applications, except occasionally Google Chrome, which seems to have no effect on performance.
Both systems are running the latest version of After Effects CC (2014) and using the Classic 3D renderer.
System 1 MAC PRO:
Mac Pro 12 core 2.7 GHz Intel Xeon E5
dual AMD FirePro 500D 3072 MB GPUs
32 GB RAM
OS X 10.9.4
System 2 iMAC:
iMac quad core 2.5 GHz Intel Core i5
AMD Radeon HD 6750M 512 MB GPU
8 GB RAM
OS X 10.9.3
As you can see, system 1 is vastly more powerful, and yet no combination of memory/multiprocessing settings can get the system to render faster than system 2.
It doesn't seem to matter how much or little RAM I reserve for other applications (I have settled on 4 GB), or the number of CPUs I reserve for After Effects. The one setting that has improved performance is turning OFF render multiple frames. And even then it only brings the performance of the Mac Pro up to par with the iMac. I have cleared my cache, rebooted the computer, and read everything I can find online regarding the optimization of render settings.
Here's a comparison of the respective CPU Loads:
iMac
Mac Pro
With such a low CPU load, After Effects is obviously not utilizing the resources available to it on the Mac Pro. What a waste.
Can anyone help?

There's plenty of debate about the new Mac Pro vs a kitted out iMac. Benchmarks show that some iMac After Effects processing can actually be faster than on a Mac Pro, depending on the content and some other factors. If you're using software that has been optimised for the Mac Pro's GPU-centric architecture, like Final Cut Pro X, you will see great benefits.
mac pro vs imac
In my own facility recently we opted out of purchasing Mac Pros this year, and bought top-end iMacs instead. The benefit to cost ratio simply didn't make sense for us right now. Mac Pros are awesome machines, but a significant component of their cost is the dual GPUs, which are simply no benefit to After Effects.
Reports say that the After Effects engineers are working on a major revamp of the After Effects processing system, so I'm betting you will realise far greater benefits from your Mac pro in coming AE versions. For now, you may continue to see performance that is not spectacularly better than a souped-up iMac, depending on the type of processing involved.
I've seen a few benchmarks that suggest the 8 core systems give better bang-for-buck than the 12 cores. Try reducing your processors to 8 in After Effects and see if it makes a difference. With 8 cores, allocate 3GB of RAM per core to leave some RAM for the OS.

I have the current Mac Pro the entry level with the default specification and i feel some slow performance when applying after effects on my videos using final cut pro and also rendering a video takes long time ? what upgrades do you guys suggest?

i have the current Mac Pro the entry level with the default configuration and i feel lack of performance when applying after effects on my videos using final cut pro and also rendering a video takes long time ? what upgrades do you guys suggest i could do on my Mac Pro ?

256GB SSD it shipped with will run low and one of the things to watch.
Default memory is 12GB also something to think about.

Is MAC Pro (late 2013) compatible with Intel E5 or E7 series 10 core CPU?

http://macperformanceguide.com/MacPro2013-CPU-upgrade.html
Someone did some testing and these Xeon processors scale differently, turbo-boost means it can put a core to sleep when it isn't needed and give more to the cores that are.
But, the number of apps that do use more than 8-core are in short supply.
Then there is the contention between cooling and whether the cpu or the twin GPUs get preference, OS X won't allow both to ask for full 100%.
We assume you know all there is about cpu scaling and usage and just need to see which ones are on Intel's list that are pin compatible and have the right thermal requirements and such.

2008 mac pro will not boot with HD 5770 installed.

Does anyone have suggestions for this. When I say it will not boot, I mean it will not respond at all to the power button if the card is installed (or at least if the power cord for the card is plugged into the motherboard. This is a mac pro version 3,1 with 8 cores 2.8 xeon, 22GB ram, running 10.6.8. Boots fine with xt2600 but will not boot if the 5770 power cord is plugged in. THis is an apple specific card from B and H. Perhaps I received a bad card. I have tried with and without the xt2600 installed and have tried in slots 1 and 2. I do not have any other PCI cards installed. Iknow this is not an "officially supported card" but it seems to work for everyone else.

Sounds like the ATI 5770 issue to me.
And 5770 worked on 1000s and 1000s of Mac Pro all models, like mine a 1,1 (there is even a thread of 160+ posts)
Where did you buy the cable and card, if from Apple and it is recent, exchange.
You are saying you never got to work...

Can a shell for mac pro 13" be used with a mac pro Retina ?

Can a shell for mac pro 13" be used with a mac pro Retina ?
Thank you.

No.
The entire enclosure is tuned for both external jack placement, EMI-RFI radiation, airflow, and for cooling. You need exactly the correct shell and fans for the electronics you wish to install in it.

I have an early 2008 Mac Pro, 8 gb ram with a Dell 27" display and a 42" LG TV. I am thinking about upgrading the stock ATI Radeon 2600 graphics card for better resolution, preferring 2 dvi outputs. Does anyone have any suggestions on the best card?

Does anyone have any suggestions on the best graphics card for these larger displays for the best value?
Thanks,

I recommend you install nothing older than the Apple-firware 5770, about US$250.
RE: Mac Pro Replacement Graphics cards
1) Apple brand cards,
2) "sold in the Apple store" cards, and
3) "Mac Edition" cards ...
... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:
1) Apple brand cards:
• Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5
• Apple-firmware 5870, about US$450
2) "sold in the Apple store" cards
• NVIDIA Quadro 4000, about US$1200
• NVIDIA Quadro 5000, about US$2500
3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:
• SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1
• EVGA GTX 680 Mac Edition, about US$600
The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.
If you are Meet ALL of these:
• running 10.8.3 or later AND
• don't care about "no boot screens" etc AND
• can re-wire or otherwise "work out" the power cabling, THEN:
You can use many more cards, even most "PC-only cards"

Emac / PC cross over cable

Hello learned colleagues,
is it possible to connect an E-mac to a PC using their ethernet ports and a cross-over cable, (no switch)
I need to share files between both computers.
assistance appreciated

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?

Use of straight through and cross over cable

hi,
according to icnd1, we need to use crossover cable to connect similar devices, lets say router to router or switch to swicth..
does this really matter? I mean, what if i use straight through cable to connect one switch to another?
thanks

Hmm, I don't know, does it really matter whether the link between devices can be used? (Laugh)
As the other posters have noted, many (newer) devices now support auto MDI/MDIX, but some don't. (Also, on devices that do, auto negotiation might be required to be enabled.) Some older devices sometimes have "special" uplink ports or manual method to switch the port's MDI/MDIX setting, and for those, too, you can use a strait through cable.
If none of the above, however, you'll need a cross over cable for "similar" device types, i.e. those whose tx/rx pins, on the port, are the same.
You need a cross over cable if both sides are MDI or MDIX (i.e. the same), straight cable if both sides are different.

Cross over cable

Do I need a cross over cable to connect my cable router to my Time Capsule via the WAN port on each unit ?

No.
Use a regular CAT5e or CAT6 Ethernet cable.

Why are the Mac Pro's dropping their server connection over a PC network.

This seems to be a common thread on the discussion, but I can't find a resolution. I have a mix of G5s and Mac Pro's all running 10.4.10. All the machines are set to manual 100BaseT Duplex. The Mac Pro's constantly drop their network connections or show write errors when you are trying to save. Can someone point me in the direction of the answer? thanks.
