IMac G5 Ethernet interface specifications

Hi,
On Apple's web site, this page:
http://www.apple.com/imac/specs.html
Apple states the iMac G5 has a built-in 10/100/1000BASE-T (Gigabit) interface.
On this (below) Apple web page describing the iMac G5 external ports:
http://docs.info.apple.com/article.html?artnum=86813
The Ethernet port is described as 10/100 Base-T.
Which is correct?
Thanks

If it is a 20 " 1.8 it would be a Rev A sold before May/2005 and would have come with Panther instead of Tiger. There are other differences too. 20 " Rev B's came with more base RAM 512 mg, 2.0 Ghz processors, built in Bluetooth and Airport, built-in Modem. Any spec on the Apple store site would be Rev B. The other link would probably be in a archive somewhere. Hope this helps,,,, Bob :~))

Supplemental Ethernet interface on iMac G5

Hi,
Is there a way to ad another physical Ethernet interface to a iMac G5 PPC ? My goal is to plug it on both private and public networks. Its user can't vpn to my gateway and needs Timbuktu on it, the only solution is to set it up with a public adress.
Thanks for your help

well u can install one as its a fixed unit, but you could buy a usb ethernet port and plug that in

Netctl: Using same ethernet interface for PPPoE and LAN

Configuration overview
One ethernet interface connected to a switch which has both the LAN and my ADSL router (running in bridge mode).
My Arch PC should connect via PPPoE (possibly multiple connections) to the ISP and be able to access the LAN simultaniously. (Connection sharing is another goal, but that is not yet relevant...)
The main reason for not changing the setup is that some other people on the LAN use their own ISP accounts over the same line.
I currently have two netctl profiles, adsl (PPPoE) and ethernet (LAN).
I also want the ability to run two PPPoE sessions simultaniously (with routing to determine which data uses which connection). (This is not currently relevant, but have been in the past and might be again in the future...)
The problem:
I'm unable to connect to both the ethernet and ADSL profiles simultaniosly.
I tried to switch to Network manager, but it has a known bug preventing the same interface from being used for both plain LAN and PPPoE.
The workaround that currently seem to work, is to use ifconfig to manually add an IPv4 address to the ethernet interface after connecting the PPPoE session.
The systax for a PPP profile also have the unusual feature that its "Interface" value refers to the underlying interface, rather than the created PPP interface.
I currently have it working on my Ubuntu HDD and previusly had it working on Gentoo.
(Under a standard Windows XP / 7, it works with a single connection, but multiple simultanious PPPoE connections require soem non-standard tools...)
The Ubuntu setup
eth0 is set up by NetworkManager (I didn't have the option to avoid that one...) and I have the PPPoE connections configured in my /etc/interfaces: (ppp0 is not currently in use, was previously)
auto lo
iface lo inet loopback
iface ppp0 inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider-local
auto ppp1
iface ppp1 inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider-intl
I then have these files under /etc/ppp/peers: (with the name mathing the "provider" line) An example below. (passwords are in the /etc/ppp/*-secrets files)
unit 0 # This specifies that the created connection uses ppp0, differs in others.
noipdefault
hide-password
noauth
persist
plugin rp-pppoe.so eth0
user "myuser@radius-domain"
Arch setup:
ADSL profile:
Description='ISPName'
Interface=enp4s0
Connection=pppoe
User='username@radius-server'
Password='mysecret'
ConnectionMode='persist'
#UsePeerDNS=true
# Override default LCP parameters from /etc/ppp/options
LCPEchoInterval=15
LCPEchoFailure=10
Ethernet profile:
Description='A basic static ethernet connection'
Interface=enp4s0
Connection=ethernet
IP=static
Address=('192.168.0.8/24')
Solutions / Workarounds
1. Manually configuring a IP after connecting PPPoE
2. Not using netctl for pppoe, rather using the pppoe-setup tool
3, Figuring out the correct netctl setup for this scenario - which is what I need your help for...
Possibly related links
https://bbs.archlinux.org/viewtopic.php?id=163956
https://wiki.archlinux.org/index.php/Sh … Connection - Insists that an extra interface is needed for sharing connections - which is not a fundemental Linux requirement

I used to use ubuntu & if you reboot into it (if you can) & run:
$ ifconfig
you will see eth0 & ppp1
ppp1 will be set as the default gateway.
Your issue in Arch is that you currently want the PPPoE interface to be the same as your LAN, this will not work at best you will need to bridge the 2 BUT I think what you should do is use the networkmanager profile as a guide & have netctl create an adsl interface called ppp1 & set that as the default gateway
thus:
Description='ISPName'
Interface=ppp1
Connection=pppoe
User='username@radius-server'
Password='mysecret'
ConnectionMode='persist'
#UsePeerDNS=true
# Override default LCP parameters from /etc/ppp/options
LCPEchoInterval=15
LCPEchoFailure=10
I think this will work, try it & good luck
PS:
I do not use netctl as I use dhcp but you might even be able to configure netctl to set ppp1 as default gateway as a "post-up" command OR just create a systemd service to do it after the relevant netctl services are up

Ethernet interface won't go up?

Hello!
I've been using my Arch-box as a router (among other things) for a while now.
It has 2 Ethernet interfaces (wan_eth0, lan_eth0) and 1 Wireless interface (lan_wifi0); One of the Ethernet interfaces connects to the internet, while the other can't seem to connect to anything at all.
The Wifi is excellent, but works as a bottleneck. I'm not super-experienced with Arch/Linux but I've used it (somewhat passively) for several years, but I haven't been able to figure out what's wrong with the interface despite several attempts. A recent update forced me to reconfigure the network settings (adding a bridge interface, lan_br0), which prompted me to try again, but I haven't gotten anywhere.
I use udev to change the interfaces' names, netctl to create the bridge interface, hostapd to host the Wifi AP, iptables is properly configured for NAT, dhcpd listens to the server's LAN IP (assigned to the bridge interface), and dhcpcd runs on the external interface.

I have a working cable connecting lan_eth0 to one of my PCs.
Unfortunately I can't try the lan_eth0 device in another computer, nor connect it to another computer than it's already connected to.
Thanks for any help!

Usually you would have a switch or hub in between there (?). I'm not really up to date on this but I think, earlier when not using a switch/hub you would have needed a cross-over cable to do this. A few searches on google reveal that this may not be needed anymore. Depending on how old your network card is...
The wiki says "Note: If one of the two computers has a gigabit ethernet card, a crossover cable is not necessary and a regular ethernet cable should be enough".
(https://wiki.archlinux.org/index.php/Internet_sharing)
Also it seems that you can check using e.g. ethtool looking for Auto-negotiation.
1) The connection itself has never worked, but the cable is as good as new and should be working.
2) The Arch box (which has lan_eth0) is supposed to act as a hub (or a router specifically), though it only has two ethernet interfaces (lan_eth0 & wan_eth0) and one Wifi (lan_wifi0). The wifi works fine.
It seems I haven't been using a crossover cable, though. I read up on it a little and apparently if the colors of the pins on the ends of a cable are in the same order, they're "regular" aka "patch" cables. I have a few cables with differently ordered pins, but they're marked "patch cable", and either way I'm pretty sure they don't work.
Also, apparently if the network card has "Auto-MDIX", it doesn't matter what kind of cable you're using, which is probably what the wiki note refers to. I don't know how to check if my card has that, I'm going to google it now.
I'm not familiar with ethtool, but it appears I can't get much information about lan_eth0? I understand that much of the information would only be available when the interface is up, but shouldn't there be more than this?

UPDATE:
According to this webpage my card does not have Auto-MDI, so I -must- use a crossover cable. I'll try it and see if I notice any difference.

Ethernet Interface Details

I think this is the most appropriate forum for this question!
For one of the programs I'm using (an open source VAX emulator called SIMH) I need it to make a connection to an Ethernet interface but in such a way that I can communicate with the OS X Host (via FTP, NFS and other network-related protocols). The emulator is built with the libpcap library.
I've seen some comments in other places where they show how to use the Tun/Tap drivers to provide this type of bridging on Linux hosts, but I understand that this is not suitable for OSX/Darwin.
This is an area that I have little or no knowledge and I'm wanting to learn about this in the belief that, if I understand what is going on, then I'm in a better position to evaluate other's solutions and to develop my own. However, there appears to be little on the Internet about this - at least with the search keywords that I'm using!
Can someone please point me to somewhere that explains this whole area of network interfacing as it relates to Darwin and OS X? Any references to get me started would be appreciated.
Thanks
Susan

Probably the place you want to start is here:
http://developer.apple.com/documentation/Networking/index.html
And then, based on my interpretation of your description, more specifically here:
http://developer.apple.com/documentation/Darwin/Conceptual/NKEConceptual/intro/c hapter1_section1.html
Also, the tun/tap drivers are available for OS X, most commonly through http://www.tunnelblick.net/ but also from other locations. A search for tun tap for OS X will reveal numerous resources.
Hope this helps

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!
lennydas

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

How can I connect Apple TV to iMac with ethernet

AppleCare told me to plug the Apple TV into the iMac using ethernet to transfer the iTunes content faster with less glitches. But how do I see the Apple TV screen on my iMac to configure it??? When I connect Apple TV using ethernet, nothing appears on the iMac screen.

This only applies if you have a first generation Apple TV. Also I hope you have a router and are not connecting the ATV directly to the iMac.
Usually I sync my First Generation Apple TV wirelessly, but sometimes I'll have some huge media files I want to sync on it which can take a long time. In those cases all you do is connect your Apple TV via ethernet cable to the same router your iMac is connected to. Don't worry about it not being connected to a tv because all you are going to do is SYNC your Apple TV. If you do not see your Apple TV in iTunes, turn off the Apple TV, and quit iTunes. Then turn on the Apple TV first, wait a minute and then start iTunes. Once iTunes sees the Apple TV, manage your content, then sync it.
Once the Apple TV has completed its sync, quit iTunes. Unplug your Apple TV, and then put the device back by the TV you want to enjoy the content on.
I have done such a thing a few times and it works flawlessly.

Setup more than one ethernet interface

Hi,
On a 10.5.2 server, I have 4 ethernet ports, 2 on Lan and 2 on Wan with public IP.
What I am suposed to do first :
1- Setup 1 lan interface, DNS, others interfaces an d thne services
2- Setup 4 interfces, Dns, Services
3- Other
Services planned on that Xserve : DNS, OD, Ical, VPN, MAil, Web.
Thank's four your help
Eric Sudan

Thank's for your response servantofserver,
I'll have an internal DSN, so I'am not sure of one thing :
What ethernet interface is suposed to be the "primary" ?
One of the lan, or one of the wan ?
Can it be changed later, changing the order by drag and drop ?, need to use changeip ?
Thank's
Eric

How do I set up an ethernet interface on MacBook Air - no ethernet option showing in network pane

I need to connect to internet via ethernet as no WiFi in my location. I have tried to add ethernet interface from network settings but no option for ethernet appears when in the network pane.
I have a MacBook Air running OSX 10.7.5
Any advice on how I can do this? Thanks

Have you plugged a USB to Ethernet adaptor in and connected it with an Ethernet lead to a router? After doing this you should see:

Nexus 5000 - Odd Ethernet interface behavior (link down inactive)

Hi Guys,
This would sound really trivial but it is very odd behavior.
- We have a server connected to a 2, Nexus 5000s (for resiliancy)
- When there is no config on the ethernet interfaces whatsoever, the ethernet interface is UP / UP, there is minimal amount of traffic on the link etc. E.g.

- This behavior is seen on both 5Ks
- I've tried using a different set of ports, changed SFPs, and fibre cabling to no avail
- I can't seem to understand this behavior?! In that, why would configuring the port cause the link to go down?
- If anyone has experience this before, or could shed some light on this behavior, it would be appreciated.

I had identical issue
Two interfaces on two different FEXes were INACTIVE. I have two Nexus 5596 in vPC and A/A FEXes.
I also use config-sync feature.
Very same configuration was applied to other ports on other FEXes and they were working with no problems.
interface Ethernet119/1/1
inherit port-profile PP-Exchange2003
I checked VLAN status associated with this profile and it was active (of course it was, other ports were ok).
I solved it by removing port profile from this port and re-applied it... voila, port changed state to up!
Very very strange.

IMac (on Ethernet) Can No Longer Stream to Airport Express (on WiFi)

After years of reliable service, all of a sudden I cannot stream music from iTunes on my iMac, via my Airport Express, to my stereo system.
First, a bit about my configuration:
   * iMac connected via Ethernet to a wireless router (D-Link DIR-655).
   * iMac Airport (WiFi) is turned off.
   * D-Link sets up a wireless network, and Airport Express joins the network.
   * Airport Express does not set up its own network, it's simply a client of the existing D-Link wireless network.
   * iTunes "sees" the Airport Express, and can stream audio via AirPlay.
   * iPad also joins the wireless network, and also can stream to the Airport Express via AirPlay.
   * iMac running 10.6.8, with all software updates applied.
   * Airport Express running latest firmware (7.6.1).
Well, that was a few days ago, when "it just worked". But for some unknown reason iTunes could no longer "see" the Airport Express.
So I took my Airport Express to the Apple Store and they did a Factory Reset, but it did not solve the problem. I figured my rather old Airport Express was failing, so today I bought a new one. The symptoms have changed a bit, but even after spending an hour on the phone with AppleCare, it doesn't work properly.
Now, the only way the iMac can stream to the Airport Express is if the iMac also joins the wireless network. In fact, now with Airport turned OFF on the iMac, the Airport Utility cannot see the Airport Express. But here's another weird thing: when I use the IP address of the Airport Express, the Airport Utility CAN connect with and manage the Airport Express, even with Airport turned OFF on the iMac!
I should also mention, the iPad has no issues whatsoever connecting to the D-Link's wireless network and streaming music to the Airport Express.
This all seems like something might have changed on the D-Link wireless router. But for the life of me, I cannot figure out what setting(s) on the router might allow the iMac - over Ethernet - to stream audio to the Airport Express.
Another thing. When I have Airport turned on on the iMac, it can "see" and stream to the Airport Express, but the music has very frequent drop-outs. Could this be related to the fact that the iMac has two IP addresses (one on Ethernet, one on WiFi)?
My goal is to get things "back to normal", where I can turn off Airport on the iMac, and all LAN and WAN traffic from the iMac goes over Ethernet. I have a few questions (for now :-)
   * Since my iMac has two connections to my LAN using two IP addresses (Ethernet & WiFi), is that likely to cause any issues?
   * When two computers join the same wireless LAN, can they effectively talk directly to one another, or does the wireless router need to be involved every time one computer sends a TCP or UDP packet to the other?
   * Do routers (or the DIR-655 in particular) tend to have any firewalls or policies that control connections on the LAN between Ethernet and WiFi clients?
   * Since AirPlay uses TCP port 3689 and UDP port 5353, would the DIR-655 need any special configuration to "open these ports" so an Ethernet client can connect with a WiFi client?
So, any help would be most appreciated!
Thanks!
Jim

I am having a very similar issue. I use my Airport Express (AX) to stream music from the computers on my network to my stereo via Airplay. I have AX set up to wirelessly join my existing wireless network, which uses a D-Link DIR-655 router hooked to a Time Warner cable modem. I can succesfully connect all of my wireless devices via Airplay, through iTunes to my AX, including two laptops and an iPhone. However, my primary desktop PC, which does not have a wireless card is linked directly via ethernet cable to my D-Link router, and it is not able to see my AX. Similar to your case, I can see the Airport Express from my PC through my Airport Utility by directly typing in the IP address. Note that the AX set-up option to allow Ethernet clients is checked. I also noticed that my laptops will stop detecting AX if I directly connect them to my D-Link router via Ethernet and turn off their wireless cards. They will resume detecting AX when I turn their wireless connections back on. I have tried every conceivable setting of my D-Link router to no avail.

HT2497 do I connect my airport express to my modem via the WAN port and then connect to my imac via ethernet cable?

Do I connect my airport express to my modem via the WAN port and then connect from airport express to my imac with ethernet cable? Is that how you "hard wire" the connection? Because when I do that, I still can't get online. Thanks.

What is the make & model of your modem?
You pretty much stated the correct wiring. There should be an Ethernet cable connected between the modem and the WAN (circle of dots) port on the AirPort Express base station.
Anytime you change networking hardware it is always a good idea to perform a complete power recycle of that hardware. Check out the following AirPort User Tip for details. Please post back your results.

FieldPoint real-time controller or Ethernet interface

Good Afternoon,
The first feature listed on the FP-2000 product page is:
Stand-alone embedded real-time controller or Ethernet interface for PC-based distributed I/O.
Has anybody successfully implented a FP-2000 as an Ethernet interface for PC-based distributed I/O? In other words, have the FP-2000 act like a FP-1600?
There are some discussion forum threads that dance around the subject but I have not found one that really answers it.
Thanks,
Ed
Solved!
Go to Solution.

Hi edlad,
After playing around with a FP-2010 for a while, I do believe that you need to install LabVIEW Real-Time on the controller in order for it to work, even if you are technically not using it because you are not running a VI/executable on the controller. As far as your issue with installing LabVIEW 8.5.1 on a FP-2000, that is troubling because there should not be an issue doing this at all. In fact, I have personally been able to install LabVIEW 8.5.1 on many FP-2000s. For that issue, I would suggest reformatting the FP-2000 from MAX and try again.
ThinkG: Regarding your question about using a cFP-2220 to communicate with Lookout, I am not sure because Lookout support is handled by our Shanghai branch via email only. However, I do know that you can use that second ethernet port to communicate with another FieldPoint network module (cFP-180x) using the FieldPoint drivers. Here are a couple good KnowledgeBase articles regarding that configuration. I hope they are helpful.

How to change the Ethernet Interface name in Solaris 10

I have to install Oracle 10G RAC on three nodes with different ethernet cards, but the ethernet interface name must be the same which is the precondition for Oracle RAC installation.
So I want to know how can I change the ethernet name in Solaris.
For example, the ethernet name in the OS is "ce0", how can i change the interface name "ce0" to "e1000g0".
bash-3.00# dladm show-dev
ce0 link: unknown speed: 1000 Mbps duplex: full
ce1 link: unknown speed: 100 Mbps duplex: half
ce2 link: unknown speed: 100 Mbps duplex: half
ce3 link: unknown speed: 100 Mbps duplex: half
ce4 link: unknown speed: 100 Mbps duplex: half
ce5 link: unknown speed: 0 Mbps duplex: unknown
Thanks in advance.

You can't. The ce or e1000g refers to the driver as well as the adapter itself. The only exception I am aware of is: the ipge and e1000g which both refer to the Intel Pro 1000.I'm pretty sure I've renamed a driver in the past (and all references to it in name_to_major, path_to_inst, driver_aliases, and minor_perm) and had it function just fine after 'plumb'ing it up. However I just tested this by trying to turn a 'pcn' driver into a 'foobar' driver on a vmware box. It looks like everything works except some internal bits of the driver continue to create one file with 'pcn' in the name instead of 'foobar'. And since this is Solaris 10, the /devices filesystem is dynamic and read-only. I can't seem to force the change.
So while this may be possible with some drivers (and maybe only on older versions of the OS), it doesn't seem to be generally possible for all drivers on Solaris 10.

Ethernet interface disappears after waking up from sleep

Hi guys,
I've been trying to debug a networking problem without any luck and I think it's about time I ask the forum for help.
My ethernet interface no longer works after I wake up my computer from sleep. I have no idea why.
Before sleep:
# ls /sys/class/net
lo wlp2s0 enp3s0f2
After waking up from sleep,
ls /sys/class/net
lo wlp2s0
Here are the list of services I have running.

Furthermore, plugging in the ethernet cord after the computer has started doesn't connect to the internet, even when I have the ifplugd service running. I am forced to run:
sudo ip link set enp3s0f2 up
sudo dhcpcd enp3s0f2
However, I can't run these commands after the laptop wakes up from sleep since it no longer sees the ethernet interface.
I am thoroughly confused. Please help me.

It seems to be fixed after the kernel update. On an related note, I've switched from using dhcpcd to netctl. I've enabled netctl to automatically connect to the network using:
# systemctl enable [email protected]
# systemctl enable [email protected]
So when I check for the status of the ethernet profile, I get told that's it's inactive.
#netctl status ethernet-dhcp
netctl@ethernet\x2ddhcp.service - Networking for netctl profile ethernet-dhcp
Loaded: loaded (/usr/lib/systemd/system/[email protected]; static)
Active: inactive (dead)
Docs: man:netctl.profile(5)
But I turned off the wireless, so I must be connected to the ethernet, So how do I know which profile I'm connected to?
