T23 Ethernet Port
Greetings,
Thinkpad T23, 2647-2KU. Some time ago the Ethernet port stopped working. All the lights were correct, just could not ping to the outside. Replaced the daughter board but still can't get out. I do have wireless but would like a LAN connection at times. Suggestions other than a new MB?
Rob
OK, at least we know that the system is "seeing" the card...which still doesn't mean that the port is working.
I'd try downloading and burning a copy of a "live" Linux CD, and testing the port there. Make sure that the LAN cable is plugged when booting the "live" CD.
This is the distro that I used on the last T23 that I owned:

Good luck and keep us posted.

The ethernet port on the X61s doesn't work while docked in the Ultrabase but does when not in the Ultrabase.
Is this normal? If not how do you get the port to work while in the UltraBase?
Solved!
Go to Solution.bhohenstein, welcome to the forum,
it is by design that the ethernet port on the ultrabase is a "pass through" port, like the VGA and modem ports. The system can only support one ethernet port. When you dock the ethernet port on the ultrabase becomes active and the internal ethernet port becomes disabled. Attach your ethernet cable to the ultrabase and everything should work fine.
Hope this helps

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well. -
Dsl modem failure caused malfunction of ethernet port. In attempt to solve problem I did a clean instillation of Leopard 10.5.4 and then update to 10.5.5 with access to internet through apple usb to ethernet adapter. If I attempt to update software to 10.5.6, .7 or .8 it freezes my network system preferences and computer will no longer shut down. The network connection assistant also no longer sees a connection to the internet throught the usb/ethernet adapter. I have checked they systerm Tech tool deluxe which shows no problems and also used hard drive utility on instillation disk which found no problems. Permissions were also checked as well and no problems noted. Any thoughts as I really like my imac G5.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

Built-in ethernet port not working in unibody Mac Mini
Hi,
So ever since I acquired this new mac mini I haven't been able to get it to recognize any devices connected via ethernet. I obviously checked the cables and all is good there. I tried connecting it to another mac, and while the other machine was detecting a device (the mac mini) at the other end of the cable, the mac mini kept saying that the cable is unplugged or the device off.
After several days of having the issue I decided to remove the ethernet service from the network preference pane to set it up again but to my surprise, the built-in ethernet option was not available (I only got airport, firewire, bluetooth DUN, VPN, PPPoE and 6 to 4). At this point I tried removing the networkinterfaces.plist file form the system configuration folder in the system preferences folder to no avail. I then tried to zap the PRAM, NVRAM, reset the SMU, SMC and all that kind of things to get the port recognized by the system but no luck.
When I look at the system profile I get these weird results in Ethernet Cards:
pci14e4,4353:
Type: Other Network Controller
Bus: PCI
Vendor ID: 0x14e4
Device ID: 0x4353
Subsystem Vendor ID: 0x106b
Subsystem ID: 0x0093
Revision ID: 0x0001
Link Width: x1
BSD name: en0
Kext name: AppleAirPortBrcm43224.kext
Location: /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AppleAirPortBrcm 43224.kext
Version: 425.16.2
Comparing it to other macs I have It should read "ethernet" rather than that strange pci name on top and the kext name shouldn't read airport but something like AppleIntel and in location it shouldn't direct to the IO80211Family.kext package but rather to the IONetworkingFamily.kext.
So I popped in the system install DVD and fired up System profiler and at that point I didn't even get an "ethernet cards" option in the left side pane. So this is leading me to believe that the hardware is not being recognized at all, so maybe it's damaged. I did replace the HDD with a bigger one and change the RAM modules to bigger ones but I don't think I could have damaged the hardware in these processes, also I don't see how this would affect the ethernet port as it's integrated to Motherboard and didn't messed with it at all (I was very careful, to say the least!).
The last thing to do is reinstalling the system but I don't think it'll help (after seeing that the ethernet port is not even being detected by the install OS) but I need to offload all the data from my internal disk and at the moment I don't have an spare drive to do it.
So, what's the recommendation? A field trip to an Apple Store? Closest one is like 3,000 km from where I am right now, so...
Well, thanks for any pointers, suggestions and help in general.I do not have any answers for you. Yes it appears to be reading what should be an ethernet card as an AirPort card. Have you played around with trying to install another version of Mac OS X other than the version that shipped with the Mac mini? Apple has long told us that we should not install a version of Mac OS X that was older than the shipping version. With the Mid 2010 Mac mini, the Restore DVD has the only version of Snow Leopard that will work with this Mac mini's specific hardware. At least until Apple releases 10.6.5. If you have installed other versions of Mac OS X, then erasing the HDD and installing the OS from the Restore DVD(s) that shipped with the mini may get you back to the point you need to be.
Unfortunately I think that you voided your Apple Warranty when you installed the different HDD. That was always a question in the past when folks wanted to open the former version of Mac minis and upgrade the RAM. But with the 2009 models folks started reporting here in the Apple Discussions that Apple was informing them that they had voided their warranty by opening their Mac mini. This new model made the RAM user upgradable, but the User Manual specifically states on page 43, 54 and 61 that there are no user serviceable parts in the Mid 2010 Mac mini except the memory.

Mountain Lion Mac Mini Server Ethernet Port Not Working
I have a Mac Mini Server and once I upgraded to Mountain Lion Server the Ethernet port is unresponsive. It worked before upgrading. Is there something with Mountain Lion Server that is causing the Ethernet port not to work properly?

Hello,
I have a DSL modem that is also a WIFI router as my main WIFI network from room A. In room B, I have a TC wirelessly joining the existing WIFI network (not creating a new one). That works fine, I have one SSID, and I can wirelessly access the TC disks and backup my Mac on my TC.
Now, I would like to connect a wired device (with on WIFI) to the ethernet port of my TC. Unfortunately, the ethernet ports of the TC don't seem to be "activated" as they do not have internet on them.
More precisely, I'd like to connect a GE Cordless Skype Phone Model# 31591 (http://www.gephones.com/products/skype/dect-6-0-expandable-digital-cordless-phon e-with-skypetm.html) that connects to a router via Ethernet. I'm aware that I could simply connect it to the DLS router, but that's not what I want... Is there any way to activate the ethernet ports of the TC while in "join" mode ? Or do I really have to buy a Airport Express to create my main network and then extend it ?!?Thanks, the reason why I asked again, is because you told me to start another thread with the specifics of the device I want to connect, so I did
Not a big deal, and it is easy to become confused.....but to be clear about this
Your question.....
is there a way I can connect my Bluray player to the TC ?
My Answer.....
Please start a new post for that. Tell us the make and model number of the player and whether you plan to connect using wireless or Ethernet.
so I tried to creat the main WIFI network with a first-generation Airport Express M9470LL/A (802.11b/g, no "draft N" or "n" support) and the TC wouldn't extend it either, is it too old/not supported
Unfortunately, the "extend" setup will only work with "n" devices. The older Express does not have a setting to "Allow this network to be extended", so the Time Capsule cannot pick up the signal.
I'm not sure what else to suggest other than what I already have. I'm assuming that you do not want to buy another new Airport Express. -
Ethernet port on MacBook Pro only works under certain conditions
Since I've purchased my MacBook Pro over two years ago now with an initial installment of OSX 10.5.x, I've had a small annoyance if while the OS was up and running and my physical network interface was disconnected and reconnected, a connection could not be reestablished until I shutdown, restart or put my Mac to sleep and woke it back up with the cable connected to the ethernet port. It would randomly work as it should if I connected and disconnected it over and over again until the machine decided I've stimulated it enough to allow me to use it. But it's recently become a real annoyance for me since the tab on my longest ethernet cable broke and it no longer locks it in place and now the slightest budge displaces the cable and I have to put the laptop to sleep often to reestablish a connection.
I would opt to Wi-Fi, but my Mac (surprise, surprise) out of 4 other laptops is the only one whose signal is too weak to use where I use them most. I've reinstalled the OS once to no avail months ago and the problem persisted after downgrading to Slowleopard a day after it's release.
Anyone have any ideas what may be going on? Any help would be appreciated. Thanks.Hello DavidJoyce
Best thing to do is to buy a new Cat 6 Ethernet cable. -
How can I configure one of the gateway NI9792 Ethernet port to communicate with a cRIO PAC ?
Hi NI Engineers,
I intend to use my gateway NI9792 the following way:
1. One Ethernet port for network connection. That's how I'll develop it, download software and monitor my application through my PC at my desk.
2. Can the other port be used to communicate with a cRIO device? If so, how can I do it?
It seems to be a stupid question, but I truly could not work this out!
Thanks in advance,
Luiz

Sincerely,

Thanks for the help. Looked but not clear on what I am trying to do as being possible. Can I use an Airport Express to connect wireless to a Linksys Wireless Router, such that I can then use the Ethernet ports on the Airport to either connected to a PC wired, or even use a hub off the Airport Express to allow multiple wired connections to it?
I am not looking to have the Airport Express extend my wireless network, just connect to it and provide me wired connections in a different location from where my Linksys Route is located. Would prefer to replace Linksys with all Apple, but just not possible financially yet. Thanks for the help.If the AirPort Express Base Station (AX) is an 802.11n model, then yes, you can reconfigure it as a wireless Ethernet bridge. In this configuration, the AX would join the wireless network provided by the Linksys router and its Ethernet port would be enabled for either a single wired device or for an Ethernet hub or switch for multiple devices.

Airport Extreme - creating a wired local network from a cellular hotspot without ethernet ports?
Forgive the book I've written below, please. I generally think too much info is better than not enough... I'm looking for assistance and/or suggestions since I have been unable to locate solutions on my own so far. Searching this forum has found a great number of "sort-of" related things, but all of them so far appear to involve apple-only hardware or upstream network devices which have ethernet ports. Nothing that seems to match my situation enough to extrapolate out. Maybe I'm just using the wrong keywords. Anyway....
I've recently moved to a particularly rural area with no wired internet access to speak of (well, I suppose there is dial-up, but... yeah). I've tried several different wireless varieties including satellite, the AT&T Elevate 4G hotspot and a service that used an EVDO-cellular solution(a sprint-based reseller). The former had serious latency issues which I had predicted and so was right-out. The last had signal coverage problems which their maps did not accurately reveal. Their potential mitigation was to have me invest even more money into a super-mega antenna to be roof-mounted. And even that was an uncertain fix. The AT&T solution with the 4G hotspot has been AMAZING so far and I love it. Coverage is great, latency and bandwidth fantastic.
I love it but for one exception, that is. Connectivity options.
There is a particularly limited number of WiFi connections available and only a USB network adapter for a single computer. None of my wired-only network devices can connect directly and I have significantly more WiFi connected devices in general use than the device supports.
I have an Airport Extreme that I was using as my primary connection point through a FiOS router at my previous home(and both the satellite and EVDO modems at the new place). Never had any problems with it when feeding its WAN port with one of the various routers' LAN ports. However, as has been evident by reading all sorts of posts here and elsewhere, having it connect via WiFi to the Elevate means that the ethernet ports are disabled. Not terribly useful.
The Elevate has no ethernet ports. Only WiFi and USB network connectivity.
The Elevate does not appear to have settings available to create a WDS network-- so it cannot be "Extended" via those methods, either, as far as I am able to tell.
So these are some thoughts I've had. Before I invest the time and money into them(both of which are in extremely short supply lately), I'd like to know if anyone else has already solved the issue or can tell me definitively whether these ideas, or some I haven't thought of, will or won't work. Any helpful feedback or thoughts would be sincerely appreciated.
Options I've considered, but are uncertain:
-A Wifi/Ethernet or even ethernet-only router which has a USB WAN uplink(I've had a few bites on searching, but nobody seems 100% clear on the capability for the models I've located). I could plug the Elevate into that USB port and then from there I'm golden. If this is the best option, then can someone recommend a brand/model that they know will work in this way?
-WiFi Access Point (Airport Express, maybe?) that will connect to the elevate via WiFi, and then use its single Ethernet port to serve as the APExtreme's WAN uplink. (I don't know if this will work at all, actually...)
-Connect to the computer via USB, run some kind of network bridging software (which I don't know what the heck that would be) to bridge between the USB Network and the Ethernet port, then run a hard wire from there to the APExtreme's standard ethernet WAN uplink. This is going to be a "last resort" option since it involves software I'm unfamiliar with, even unsure of availability for Mac, and requires the computer to be running and configured properly at all times. Given the way my kids abuse a computer, I can't be certain of anything involving this option.
-Some secret method of turning on WDS capabilities in the Elevate which would then allow my existing base station to become a second node in the chain. I really wish someone could tell me this is possible if only I'd push the right buttons. I see this is as the absolute best option, if it can be done. Cheapest, anyway.
Current set-up:
AT&T Elevate 4G hotspot
WiFi connected devices(rotating since Wifi connection count is limited): Mac PC, 2 iPads, 3 iPhones, Apple TV, a Nokia mini-tablet, a Kindle fire, Wii, XBox 360, an old dell laptop issued by my office.
Apple Aiport Extreme base station
Wired connections: blueray player, television, satellite TV pay-per-view uplinky device thing.
Please, tell me your thoughts?Had the same issue here. Here is the best solution I have found so far:
Hotspot + Pepwave Max On-The-Go (w/ Load Balancing) + Airport Extreme
I have a VZW MiFi, but I believe this set-up will work with other hotspot devices. I actually have 2 MiFi Hotspots with a monthly allowance of 20G each. They are plugged directly into the Pepwave router (aka, tethered). (Note: you have to have the right cable to do this. The one that came with my Hotspot was only for charging.) If, for some reason, you cannot tether with your Hotspot device, you want a router that offers WiFi as WAN. The Pepwave will do this. The Pepwave is connected to my Airport Extreme via ethernet cable. I have the WiFi on the MiFis and the Pepwave turned off. So the only visible network is my Airport Extreme. The Pepwave is essentially just functioning as a modem.
I used to have a Cradlepoint, but I did not find it very user friendly--too complex for home use. The Pepwave Max OTG is awesome. I got the one with Load Balancing so it allows you to connect up to 4 cellular devices. If you only need the one Hotspot, you can just get the cheaper Pepwave Max OTG. The Pepwave allows me to run off one of the MiFis until I hit my 20G/month allowance, then it automatically switches to the other one. That way I never max-out on my monthly data allowance. Additionally, it gives you a real-time, hourly, daily and monthly running tally on data usage.
The guys at the 3Gstore are excellent and can help you figure out the best solution for your situation. -
RT: How do I use two independent Ethernet ports?
I have looked around at the forums and seems like no one has had a real solid answer or example on how to use 2 Ethernet ports with RT.
Right now I have two connections configured on the RT:
Primary Connection:
IP:192.168.2.181
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
DNS Server: 192.168.1.1
Secondary Connection:
IP:192.168.1.180
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
DNS Server: 192.168.1.1
After using this initial setup, I made a RT project where I used 'UDP Open' for both 192.168.2.181 and 192.168.1.180, and had them both read and write in a sequence (Read and Write for the 2.181 connection, then Read/Write for 1.180).
The computer I'm using to send the data is connected to a switch, which in turn is connected to the RT. Both the RT and my host computer have 2 ports, one of them with ports configured to be 192.168.2.x and 192.168.1.x
Using this configuration I get some weird results:
If I send a packet to 192.168.2.181, I receive it from the UDP Receive vi that has an input connection from my UDP Open assigned to 1.180. I also receive the data the same way when sending packets to 1.180 (as expected). Basicly, no matter what IP I'm sending it to on the RT, the data from either packet will arrive from the same location/vi.
Why is this? Is there anyway to fix this? Did I not configure something correctly?
Does anyone have an example of dual Ethernet ports actually working with LabView RT?
I tried checking out "KnowledgeBase 3VQ6278T: Can I Use Multiple Network Adapters in a PXI or Desktop Real-Time System?", but after following the link to the page, I get:
"Error You are not authorized to view this document". Can any NI people look into this?
Having to make two IPs with different subnet masks obviously just makes things unnecessarily complicated. Can anyone tell me why LabView/NI did this? I know for a fact this isn't a limitation in hardware.
Any help would be greatly appreciated, thanks!Hey Weizbox.
Sorry to hear you're having such a difficult time using multiple ethernet devices with RT.
Let me go ahead and get the easy stuff out of the way, the link you
have is dead because it's archived (and thus removed forever) though
unfortunately the link on ni.com wasn't corrected to point to the
following resource, which the KB was a word-for-word duplication of
(which is supposedly why it was removed):
http://zone.ni.com/reference/en-XX/help/370622C-01/lvrthelp/configuringdual/
Unfortunately, though, it's much less useful than it sounds.
Before you start feeling like a woodpecker in a petrified forest, lemme
fill you in on why the requirement is there for the two ethernet NICs
to be on seperate subnets. Simple enough, it has to do with the
network stack on both of the operating systems used for LabVIEW
Real-Time - however, the same falls true for even Windows (without
using fancy vendor-specific drivers), so let's not be too hasty.
Neither PharLap ETS nor VxWorks, the two OS's used under the hood,
support redundant network ports. Because of this, if you give two (or
more in the case of PXI and RT Desktop) ethernet devices IP addresses
on the same subnet the routing tables in the network stack get horribly
confused and literally cannot resolve the proper adapter, which either
brings down the ethernet on the entire system or makes it such that one
or more network adapters becomes useless and one adapter takes over all
network traffic (there's no way to predict which adapter that will be,
nor can you control it based on what's plugged in and what's not). On
Windows this is handled by bridging the adapters, but RT does not yet
support bridging (that opens a whole nother can of worms). Long story
short, you still wouldn't be able to give both NICs individual IP
addresses on the same subnet.
Let's take that even one more step. You cannot simply just assign both
ethernet NICs different IP addresses on "virtual" subnets, you actually
need to put both NICs on literally different subnets for the network
routing to actually work. Multiple ethernet devices for LabVIEW RT
were designed with the following mantra in mind - "The FIRST ethernet
device is designed for a TCP/IP network, the SECOND and SUBSEQUENT
ethernet device is designed for OTHER protocol uses." By "OTHER
protocol uses" I mean the second NIC should be used for RT
Deterministic Ethernet (PXI, RT Desktop, et. al.), direct connections
with other targets, and 3rd party or custom ethernet protocols.
Now, realistically, we can't expect users to not use the second NIC for
TCP/IP use, nor should we. However, if you ARE going to use TCP/IP on
the second NIC, you should only use the second NIC for connecting to an
unroutable network in the eyes of the first NIC. So, for instance, the
FIRST NIC can have an IP address of 10.0.62.128, but the SECOND NIC
would need to have an IP address on 192.168.100.23 - and the
10.0.62.128 should not be able to route a TCP packet to the 192.168.x.x
network, and vice versa. In your example I noticed that both networks
used the same Gateway - unless your Gateway is configured to identify
and seperate the two networks, it's not going to end well, and you
shouldn't expect to be able to send data from one NIC to the other NIC
(at least with what you know now). To reiterate, using multiple NICs
using TCP/IP should only be done in cases where you've got (n-1)
isolated subnets, where n is the number of NICs you have using TCP/IP.
A classic example of this is a command-based measurement environment;
the RT system uses the FIRST NIC to talk to a TCP/IP network, in order
to transfer data or provide status to a network, and the second NIC is
connected to a TCP/IP network designed specifically for measurement or
control, where one node sends commands to a single or multiple nodes on
the network at once to perform tasks (like "Take a Measurement", "Stop
a motor", "Bake me a Pie", etc...). The isolated TCP/IP subnet is free
from "random" TCP/IP traffic (especially system announcement
broadcasts) and can have whatever topology/configuration it wants. The
dual networking allows the RT system to work/communicate/perform on
both networks.
I hope this helps shed some light on your situation.
Cheers!

No internet access via ethernet port
Hi, have been using my emac via ethernet cable to router, for many months with NO problem accessing internet and others cabled to same router also having no problem and I have used my Pwr Mac wtih no problem and have never had to make any specific settings to either to access the net via the router which gets its wifi signal from elsewhere. With system preferences > network > ethernet open I can see the the router is being recognized cause it appears or dissappears as soon as I plug or unlug the ethernet cable. I open "Activity Monitor" and occasionally, very briefly, there will be data incoming( green spikes ) or outgoing( red spikes ). HD verified OK, ran disk permnissions and scripts. Have not yet run Apple or other( Micro-mat ) hardware testing programs tho I will later. Does anyone know if there is a PLIST file that can get corrupted that would affect ethernet port functioning properly? My guess it is hardware but since I can see the router is recognized makes me wonder about corrupt file ergo a system error or possibly inloaded some file that caused conflict. I also booted from my external drive and tried accessing from the cloned OS system and still did not work. The cloned system is the original has never been updated, nor has any of the applications in clone, so, if it was "system" problem the clone should have worked. However, I had cloned user ergo newest documents, library etc, so that would be the only possible source of conflicts when booted from clone system....Thx Ran

*Dns problem?*
It has symptoms of a DNS problem. The little traffic is a symptom of the problem. You said all the numbers were the same, however.
Verify DNS
apple > system preferences > network
Double click on network connection you are using.
Pick the TCP/IP tab.
Verify that you have a DNS Server. If you do not, look on your windows machine and see what the net address is. You can also pick using DHCF and still enter you DNS server address.
You can use
harddrive > applications > utilities > network utility
to diagnose the situation.
You can ping google.com. Result:

If pinging 17.254.3.183 works but pinging Google.com doesn't. You have a bad DNS Server address.
BDAqua suggests in a post.
You can use OpenDNS for looking up web addresses.
Put these numbers in Network>TCP/IP>DNS Servers for a try...
208.67.222.222
208.67.220.220
I think they now pretend you need to join to use, but you don't.

(Please note that you do not need to a joint Open DNS to use it.)

Google provides free dns lookup too. There numbers are:
8.8.8.8

Analysis: If you cannot ping Goolge.com but you can ping 64.233.187.99, then you need to enter you dns address. For some reason Mac OS X sometimes doesn't set the dns. You can set it manually.
apple > system preferences > network
tcp/ip tab and enter address of dns servers
example 162.33.160.100
You will need to use a different number.
PS.
You are a little short on stating results. You state what you did, but I have to guess the result.
Did: X
Result: Y
Did:
1) Power Book's ethernet cable plugged into router port 5. Working to yahoo.com.
2) Unplugged power book's ethernet cable from router
3) Plugged eMac's ethernet cable into port 5.
Result: eMac using Firefox was not able to access yahoo.com

Forcing a Mac with 2 connected ethernet ports to use one over the other
I have a G5 Quad and a Mac Pro that are connected to a large network (including internet) on ETHERNET 1, and they are also directly connected over ETHERNET 2 (using Jumbo Frames). I need to ensure the G5 uses ETHERNET 2, and not ETHERNET 1, to connect to the Mac Pro. They must use both connections. How do I do this?
TimI've solved the problem. When connecting to the other computer, don't map the drive from the Finder sidebar. Instead, go to the Finder, hit Cmd+K, or select Go > Connect to Server..., then type the IP address of the other computer's ethernet port that you are directly connected to. Then write an Applescript to automatically mount the drive on startup.
Example Applescript:
+mount volume "afp://192.168.1.1/"+
Compile and Save the script as an Application with none of the Options checked. Place the script on the remote computer (the G5 Quad in my situation) in a suitable location like the Documents folder for your Username.
Next, on the remote computer, open System Preferences > Accounts, and select the correct account. Select the Login Items tab, and click the + to add your Applescript application to the list. After adding the Applescript, check the Hide checkbox so the script runs in the background. Close System Preferences and you're done. Reboot the computer to verify it connects, and voila!

How to specify one ethernet port for network home directories (other for normal filesharing)?
So I'm trying to get Home Directories up and running on a 10.6.8 Xserve (waiting until I get my NFS sharepoints migrated to a Linux server [for other reasons] before moving up to 10.7 Server). But posting here since that will be happening in the next few weeks, and it might be applicable now (so I can at least get that resolved ahead of time).
I have a different DNS entry for each ethernet port: server.office.domain.com at 192.168.0.11 for the first, and homes.services.internal at 192.168.0.10 for the second. DNS lookups for both resolve correctly (as does the reverse lookup).
If I use the Server Admin to pick a sharepoint as an automount for Home Directories, everything is fine, but it picks the server.office.domain.com hostname. Picking that works just fine, but that is also the connection that feeds the filesharing. I'd prefer to split that home directory traffic out onto the second ethernet port. So I tried just duplicating the initial connection (since it can't be edited directly in Workgroup Manager) and changing the hostname to the internal one, but I get an error when attempting to log in (the client login screen gives a very helpful "Couldn't login because of an error" error message) and don't see anything in the server logs.
The client machine shows the following line:
Code:
10/20/12 5:27:42.688 PM authorizationhost: ERROR | -[HomeDirMounter mountNetworkHomeWithURL:attributes:dirPath:username:] |
PremountHomeDirectoryWithAuthentication( url=afp://homes.services.internal/Users,
homedir=/Network/Servers/homes.services.internal/Volumes/HomeDirectories/Users/ user123, name=user123 ) returned 45
(added line breaks so it didn't extend off the page)
So it looks like this is failing because the automount isn't in place, but I'm not sure how to work that out either (i.e. how do I add that making sure it uses the internal hostname?).
Any suggestions on getting this to work?
I realize one solution is just to LACP the two ports, but that is a different ball of wax (I may do that later if I get a 4 port ethernet card and performance limitations demand it).A possible solution might be this.
On ADSLBOX and CABLEBOX configure different subnets for the LAN, e.g.
ADSLBOX: 192.168.1.0/24
CABLEBOX: 192.168.2.0/24
The MEDIABOX gets these static IPs:
ADSL-LAN: 192.168.1.2
CABLE-LAN: 192.168.2.2
On the MEDIABOX, configure the two network interfaces using two routing tables.
The ADSL-LAN routing table
ip route add 192.168.1.0/24 dev eth0 src 192.168.1.2 table 1
ip route add default via 192.168.1.1 table 1
The CABLE-LAN routing table
ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2 table 2
ip route add default via 192.168.2.1 table 2
The main routing table
ip route add 192.168.1.0/24 dev eth0 src 192.168.1.2
ip route add 192.168.2.0/24 dev eth1 src 192.168.2.2
# use the CABLE-LAN gateway as default, so general internet traffic from MEDIABOX runs over CABLEBOX
ip route add default via 192.168.2.1
define the lookup rules
ip rule add from 192.168.1.2 table 1
ip rule add from 192.168.2.2 table 2
To test the setup:
ip route show
ip route show table 1
ip route show table 2
I don't know how to persist something like this in ArchLinux using netctl. Might require to write a special systemd unit for it. Above is a working example from a RedHat box at my company.

FQDN replacing server name in TED distributions
In a TED application distribution, the server name is changing to a FQDN in the distributed application. The application does not resolve the FQDN as being the server name. Any ideas?
