Setting up dual ethernet on an intel macpro server

Hello. I am new to the server setup and was wondering....I am using an intel MacPro as a server with a 3.5TB raid. I am using the MacPro as a server, connecting to a 24-port SMC switch which will feed 15 workstations. The internet is through a local T-1. My question is this....How do I configure the Macpro to take the T-1 into ethernet #1, and then out of ethernet #2 to the switch and distribute it using the DHCP service in server admin? I know how to configure the DHCP in server admin, but how do I configure the Ethernet ports on the macpro so ethernet port 1 is the T-1 and ethernet port#2 is sending the T-1 to the switch? Sorry if I am confusing you, like I said, I am new to this. Hope there is some insight available. Tahnks in advance for your assistance.

I wouldn't recommend this because most people who do this have the 'server' running not just NAT, but probably their web site, a file server, maybe directory server, and just about every other server daemon they want.
If this server has one leg in the public internet and one in the private LAN you're leaving yourself open to exposing those services to external users.
It is not possible to use Apple's GUI tools to restrict all the file sharing services to the internal LAN only. It's also not possible to use Apple's GUI to block external traffic via the firewall. This means that, out of the box, any internet user could hit your AFP server, your directory server, and every other service you're running on this box.
It is possible to secure the box, but it means a) getting under the hood and controlling the various services manually and b) never using Server Admin again because it will likely undo all the hand-crafted configuration changes you made.
If you're fine with that, then go ahead. Most people aren't. So your options are to run only the NAT service on this box (which makes this box a VERY expensive NAT device), or leave yourself exposed.
That's why I say to use a NAT router to do that task. For $50 you get a box that designed for that task and will secure your entire internal network. You can use port forwarding to permit specific incoming traffic through to your server (so you can still do what you want), and you don't have to worry (as much) about what information on the server is accessible to the outside world.

Setting up an Ethernet Hard Drive as a Server?

Hello all, I hope your year ends well and the new one starts just as. I have a somewhat quick, i hope, question regarding an ethernet hard drive that I am looking into buying. My friend and I are trying to set it up so that he can access it from the internet without being on the same network (as in: another country) and I know that certain ethernet hard drives are set up with an IP address... so my question is whether or not it is possible (and probable) to set it up as a server so that we can still access our files. I am pretty new to all this so thank you for your indulgence. Any help would be greatly appreciated.

Not sure if this is what you are looking for, but here's an option: http://www.yellowmachine.com/

Dual Ethernet will not connect if set to share Single IP address

The subject says it all. My trusty old Dual Ethernet will not connect if set to share Single IP address.
I cannot get anything but a self assigned IP address with it set to share a single IP address.
Before about Tuesday of last week I had connected to it a Mac mini, iMac, Dell Desktop, Dell Laptop, and PS3 all working fine. I think Comcast or Apple updated their system or Airport software and now the old dual Ethernet will not share a single IP address.

So far as I know, there has been no recent change in Apple's software affecting the Snow (a/k/a Dual Ethernet) base station. About 2-1/2 weeks ago, Apple distributed an update to AirPort software for Intel Macs running Tiger, but it would not have affected the base station.
Your topic implies that when the Snow is not set to share a single IP address (i.e., presumably, when "Distribute IP addresses" is unchecked in the Network pane of AirPort Admin Utility for Graphite and Snow), one of the computers is connecting to the Internet through the base station. I also imagine that the self assigned IP address you mention is the IP address of that computer, rather than of the base station, and that that computer obtains an IP address from Comcast when the Snow is not distributing IP addresses.
Assuming that that computer is connecting wirelessly, then whatever settings that computer is using for TCP/IP and PPPoE in the AirPort part of System Preferences, while the computer connects to the Internet, should be the ones used for the base station, in the Internet pane of AirPort Admin Utility for Graphite and Snow. (Most likely, it is simply "Using DHCP.") The IP address obtained from Comcast should be received by the base station, when it is set to distribute IP addresses in the Network pane, and the IP address should show up in the Internet pane. (When the Snow is distributing IP addresses, it has two IP addresses itself, a WAN IP address obtained from Comcast and a LAN IP address, 10.0.1.1, visible only to devices in your network.)
Even when the settings are correct, the Snow might not be able to obtain an IP address if your cable modem remembers the computer, which had been receiving the IP address previously. You'll probably need to shut down the computers and unplug power to the base station and cable modem. After waiting 5 minutes, restore power to the modem, then after another 5 minutes, restore power to the base station, then after another 5 minutes, start up a computer.

Any Idea if a first Gen. Intel MacPro 2.66 Xeon Dual Core running SL will run CS5 in 64 BIT mode?

Hi,
I have a Intel MacPro first Generation Dual 2.66 Xeon processor machine running Snow Leopard and I was wondering if it will be able to run PS CS5 in 64 Bit mode or does it have to be a later generation MacPro?

Bennett, I'm afraid that I don't know the answer to your question. But hopefully someone will happen along to at least give you some help, instead of answering your question with three questions of their own. Hang in there!
The original question was 'answered' with questions because the original question was so odd. CS5 has not been announced so no one can state what it can do. This is not rocket science about software that has not been released yet. If someone knows the answer to the question, they are not allowed to say anything yet. This is how prerelease Adobe software is handled.

Need hints for Optimizing Photoshop CS4 on Leopard / Intel MacPro

Just wondering if anyone had any hints for optimizing PS CS4 performance on Intel MacPro ( I have the 2.66 Dual-core Xeon) My MacPro has the upgrade ATI 1900 video card which I think is GL enabled. From what I have read CS4 now accesses the ATI 1900's GPU memory for increased performance. Is this correct? Does anything need to be configured or does CS4 automatically detect the ATI 1900 GPU?
Any other configuration in CS4 that need to be set?
Thanks.

Open Photoshop's preferences (Command+K). Click on Performance at the left. The lower right portion of the settings will say if PS detected a compatible video card. If it did, the check box for "Enable OpenGL Drawing" will already be on.
The features that OpenGL drawing adds to PS are listed here:
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb404898
That may help you decide whether or not you want it on. Personally, I turned it off. One big reason for me is paths. I have to create a LOT of paths for client work. With OpenGL on, paths can be difficult to downright impossible to see as you draw them, depending on the color of the underlying pixels. With OpenGL off, PS uses the standard complementary contrasting colors. Much easier to use.

Can I change my Dual Ethernet Airport from WEP to WPA?

I just read that WEP wireless networks aren't really secure, even when set up as "closed," but it appears that my Dual Ethernet Airport only allows WEP networks.
Can I change software or firmware to allow me to configure the Airport as a WPA network? My firmware is version 4.0.9 which appears to be the most current available.
Thanks for any help. I'm also having the problem with a dual core machine not automatically establishing with my closed airport network if anyone is keeping track, I've got an unanswered thread about it on the intel mac page.
Also, I apologize for posting this on the Airport for Windows page, I'm using a Mac, actually several.

No

How Do I setup Dual Ethernet (Snow Saucer) base as "repeater" for Extreme

Just migrated from G4 iBook to an MBP. Currently still using my Snow Saucer (Dual Ethernet) airport base station (had to communicate with the Base using the iBook, and manually enter the MAC address of the MBP).
When I go to the trouble of setting up my Airport Extreme to become the base station to which my DSL line is connected, I also want to use the old Saucer as a "repeater" to get a better signal somewhere else.
Where are the instructions for doing this?
Also, I want to know if this may be a bad idea, because IIRC I read that if the Extreme detects a device using the "old" frequency, it will downgrade itself to that frequency, and I will lose the advantage of the Extreme for any devices which could make use of it.

However, extreme and express base stations can be configured to to act as relays and receivers for Graphite and Snow base stations.
With no setting or availability of WDS capability on the dual ethernet device, I fail to see how this would be possible.
Setting this up is fiddly because you have to configure the bridges to connect to an ABS via a MAC address.
And, the ABS must also be configured with the MAC address of the other devices in the WDS, but there are no provisions to do this.
If you want, I'll send you a link for MacTracker, which lists all models and specifications.
It might be possible to run ethernet from one of the other AirPorts, configure the dual ethernet version in "bridge mode" (if possible) and then have it create a wireless network. To be part of the "same" wireless network, it would need to be setup to use the same wireless network name, security and password as the "main" network.

Setup Dual Ethernet (Snow) using Windows XP

Is it possible to configure a Dual Ethernet (Snow) Airport base station using only a pc running Windows XP? If so, which version of the admin utility should I use and what's the exact process in order to get things setup?
We've performed a hard-reset but it will not allow us to update the base station using 4.2 for Windows, because there's an error connecting to it via ethernet.
Thanks!

Thanks. That has helped point us in the right direction. In addition, I found this info particularly helpful in order to set the TCP/IP settings in the Network control panel:
http://docs.info.apple.com/article.html?artnum=106685
After changing those settings, we were able to configure and update the base station.
However, after putting the TCP/IP settings back the way they were (obtain IP automatically instead of manually), the PC connected via the LAN port and the wireless can't connect to the internet at all. The base settings reveal that it's using an IP address starting with 169.xxx.xxx.xxx which tells me it can't get a real IP from the cable modem. Unplugging the cable modem, base station, restarting, etc. aren't doing the trick. Oh so close. I'll keep you posted unless you have any further suggestions.

ABS Dual Ethernet -- Error writing configuration during hard reset mode

This has been a full day of troubleshooting this one. After downloading the Airport Admin Utility 4.2.5, I was finally able to see the old ABS Dual Ethernet via ethernet cable plugged into the LAN port from a Macbook running 10.5.2. We don't know the password to login into the base station and a soft reset hasn't stripped the password from the base station.
So.. I got ABS into hard reset mode with the middle LED blinking once every second as described in the Apple documentation, and was able to seethe ABS from the Airport Admin Utility. HOWEVER, when I try to configure the ABS, I enter my Admin username and password, am prompted to temporarily change TCP/IP settings for this computer and then "Writing configuration..." comes up.. but a few seconds later I get an error message "An error occurred while writing the configuration."
That's it. No other explanation.
No idea where to go from here.
My network settings are set in Manual mode to the following:
IP: 192.42.249.15
Subnet: 255.255.255.0
Router: 192.42.249.13
Any ideas with this one?

If I understand your post correctly, "when I try to configure the ABS" in the second paragraph refers to clicking the Configure button while trying to reload base station software (i.e., step 16 in Apple's document titled AirPort Base Station (Dual Ethernet) : How to reload software from Mac OS X).
I suggest that in order to reload the base station software, you make sure that AirPort is inactive on your computer and that the manual network settings you described are in the "Show: Built-in Ethernet" part of Network preferences.
Beyond that, I'd recommend re-doing the hard reset, possibly multiple times if it doesn't succeed the first time.
On the other hand, if you successfully reloaded the base station software and are indeed trying to configure the base station's settings, then quit AirPort Admin Utility, restore the computer's Network Ethernet settings to Using DHCP, and reopen AirPort Admin Utility (steps 18-20 of Apple's document).

Changing nat settings to open on basestation (dual ethernet) for xbox 360

i have a airport basestation (dual ethernet) and i have my xbox 360 plugged into the back using a ethernet cable and i have tried everything i know to open the nat(network address translation)
settings and i tried everything i know to open a port but i am appearantly doing something wrong.... can anyone help?? please... my xbox connects to xbox live but i can play with very few people because of the nat setting.... suggestions?

jfinley1, Welcome to the discussion area!
This "open NAT" is a relatively new thing not supported by the dual Ethernet AirPort base station (ABS).
How have you tried to map/forward/open a port?

How to set up dual monitors with a Mac Mini

The Mac Mini has only one video output port. I very nearly didn't buy a Mac Mini system because I need to work with two monitors. I use the second monitor to display information in Web pages, PDFs, and Word documents while I am working in the main window.
However, I discovered after quite a bit of Googling that it is possible to set up dual monitors using an inexpensive USB video adapter (about $70).
So I bought my Mini (1.83Ghz, 2GB RAM, 200GB 7200rpm Seagate Momentus), and I also bought a USB video adapter called the EVGA Plus.
I've installed this system and used it now for a week, and I am quite pleased with it. So I thought I'd pass this information along to anyone who's interested. Please note that, although this is my first post to this forum, this isn't spam -- I have no financial relationship with any of the companies mentioned here, other than as a customer.
LINKS
EVGA Plus:
http://www.evga.com/articles/409.asp
Their literature does not mention Mac OS X compatibility. However, the underlying technology is made by Display Link. You can download beta Mac OS X drivers from their site:
Go to Display Link to download the beta Mac OS support -- see
http://www.displaylink.com/macbetadrivers.html
The disk image includes a very well written PDF document that explains the driver's status and limitations.

NOTES
* The DisplayLink driver is beta. It doesn't support 2D or 3D accelerated graphics. You can't use it to display iPhoto slide shows, for example. However, I need to be able to display a Web page, document, or PDF in the second monitor while I am working in the first. I've found this solution to be quite acceptable for this purpose.
* Several other companies make USB video units that use the same DisplayLink support, so they should work, too. However, they are more expensive -- largely because they're set up to function as port expanders, I believe. The EVGA Plus was the only unit priced under $100 when I did my search.
* USB does not have very much bandwidth, so you might be surprised that to hear that it's possible to use USB to drive a monitor! You'll find that the display isn't as fast as DVI, but for my purposes, I've found it quite acceptable.
* The EVGA Plus comes with a terrible USB to mini USB cable that will cause all sorts of display problems. Replace it with the type of cable that is used to hook up digital cameras to a USB port.
* Once everything is installed, you can use the Displays in System Preferences (or just click the icon on the menu bar) to adjust the second monitor. You can choose display resolutions (depending on your monitor's ability, of course). Rotation works. You can also right-click the second monitor and choose a different background color or graphic.
Don't expect miracles. Don't go this route if you want to run videos or games in the second monitor. And if you get an EVGA Plus, replace that horrible cable!
I hope this information is helpful.
Bryan

There has been quite a lot of discussion here about driving twin displays with the mini, and more recently about the potential for USB video adapters to facilitate this, particularly in the light of several vendors claiming they have suitable MacOS devices and drivers 'almost ready'.
The DisplayLink solution seems to be the one most suggested as viable, though it's a pity they have not yet been able to move their drivers from beta - I suspect that puts a few people off. It's therefore good to hear of a real-world experience that should help others decide whether or not to go this route!

Airport Dual Ethernet connecting to DSL.

My normal system is a Windows XP PC connected to 2wire dsl router from SBC. My wife has an iBook(the white one)that we are trying to get connected to the internet using an Airport Dual ethernet. THe iBook has a wireless card installed and before I moved all I did was plug the airport into the DSL router and all was well. Now what is happening is that as soon as I plug the airport into the router it I lose my PC internet connection, even more frustrating is that I still can't access the interent via the iBook.
I am totally unfamiliar with the Mac OS so this just adds to my frustration. Are there any resources/guidance/books that would help a new wireless Mac user on configuring the airport to connect to the same router as a windows PC without screwing it all up?
Any help would be awesome.

PC Windows XP Pro Airport Dual Ethernet

Hello, I'm new to Mac's as well, but I hope I can help narrow down the source of the problem a little.
You said "and before I moved all I did was". I take that to mean you moved from one home to another. Does that mean that you also have a new DSL service provider (which means they provided you with the DSL router you are using. A couple things to try to semi isolate the problem, or at least try to narrow it down to one device having issues.
Try to connect to the internet with each computer individually using the DSL router, one at a time. Do they both work that way?
Try connecting the airport only, then connecting to the internet with each computer individually (the other should be powered down so it doesn't try to connect when wireless becomes available {hopefully}). Do they work this way?
If they work, or one does but not the other you have provided yourself wirh a wealth of information to offer the experts (no that's not me), I'm afraid I won't be much help beyond this. The reason for this method is that you may discover that something has happened to your system(s) (hopefully not) during your move(?), or your service provider (new) may have provided you with a faulty router (just a couple of possibilities).
Another thing, have you installed any new software, or updates recently, like just before the connection stopped working.
Hope this helps.

If they both turn on for a second or two and then it drops you back at the command line, it would appear that X is working ok.
What wm/de are you using? .... or maybe what login manager are you using?
Have you checked your /var/log/Xorg.0.log file to see what it says?
Normally when you are dropped to the command line, there would be an error message on the screen in front of you; it should be the same as in the log file, btw.
Also, when did this start happening?
Has it ever worked? If so, what changed?
