To automatically bring interface eth0 up on boot

Eth0 can be brought up by:
ip link set eth0 up
Some times when
systemctl start dhcpcd@eth0
doesn't work,
probably
sudo cp /etc/network.d/examples/ethernet-dhcp /etc/network.d/ethernet-whatevername-dhcp
and edit /etc/conf.d/netcfg to change NETWORKS=(ethernet-whatevername-dhcp) couild solve the problem.

In system-config-network the options to set a static ip address are available once you switch off DHCP.
Please mind you need some basic knowledge of TCP/IP in order to setup a TCP/IP based network... There are various sources on the internet about this, I strongly advise to read about it.

Bringing up interface eth0: e1000 device eth0 does not seem to be present, delaying initialization.

I performed a software reboot on the MSE3310. After the reboot the MSE was no longer visible on the network. I went and consoled into the device and it was operational. I ran the msed stop and msed start commands. I got this message when it tried to load eth0

Earlier in the day I had updgraded the firmware from 6.0 to 7.0.230.0.
Can I recover the eth0? Is this related to the firmware upgrade?
Thanks.

Tarik,
This procedure worked great! After adding the HWADDR parameter to the eth0 config file and rebooting the server, we are now able to access the server on the network again. Thank you very much for the quick reply!
Here is the procedure if others need this.
ifconfig -a showed the eth0 interface was renamed to _tmp462132856
[root@MSE-CPW-01 ~]# ifconfig -a
__tmp462132856 Link encap:Ethernet HWaddr 00:15:17:F1:4D:C7

Then issued
vi /etc/sysconfig/network-scripts/ifcfg-eth0
to edit the file and add the HWADDR=xx:xx:xx:xx:xx:xx
Then issued a 'shutdown -r now' to reboot the server
After a reboot, network connectivity was restored!

[SOLVED] netctl not bringing up my network at boot

I recently converted from netcfg to netctl and but my network is not coming up ever at boot time. Once the machine is booted I can bring it up manually using
netcfg start ethernet-static
It is obviously an static IP address and I copied the netctl sample script and then modified it. Here is my ethernet-static profile.

I do have two ethernet ports but from what I can tell the naming of the two ports is consistent.
netctl status shows that my ethernet-static profile is the only profile and is active.
I know I could connect without using netctl but want to get this working. Any ideas?
Last edited by kfrance (2013-06-15 04:12:06)

I fixed the problem. I changed the device name of the ethernet device I wanted to use using an udev-rule, according to the notes on the Network Configuration wiki page, to make sure that it wasn't a naming conflict and that solved it.

Wicd does not automatically connect to eth0

Wicd works fine using my wireless network. It does not automatically connect to eth0 when I plug in a cable, but I can connect to it by pressing connect manually.
I already have ethtool installed (do I need to run ethtool as a daemon???)

stabele wrote:I have two maybe naive question:
1)are you connected to wireless network before you plug in ethernet cable? If yes, than wicd does not automatically switch to wired network. Maybe you can get it done by custom scripts wicd support for each connection, but I never used this thing in wicd.
2) do you have disabled in rc.cong interfaces you want wicd to manage INTERFACES=(!eth0 !wlan0) ?
Thanks for your answers, 1) no I'm not connected to wireless, and 2) eth0 is disabled.
I found out it works fine if I connect eth0 manually and then I can remove and plugin the cable all I want and it automatically connects. This is because dhcpcd is already running for eth0 so maybe I should run dhcpcd eth0 in a boot script (although I think wicd should do this).

Netcfg/systemd not bringing up eth0 (static profile)

I installed a fresh copy of Arch on a flash drive that will power my RAID server today. So far, it's almost perfect.
The issue right now is that in netcfg fails to bring up a static eth0 profile at boot. I've got the netcfg.service enabled and if I do it from the command line, it'll come up without a hassle. Occassionally, it'll give me the "NOHZ: local_softirq_pending 08" error, but it still works. However, nine times out of ten, an error flashes by and the interface never comes up.
[root@whitebox ~]# systemctl | grep net
sys-devi...et-eth0.device loaded active plugged RTL8111/8168B PCI Express Gigabit Ethernet controller
netcfg.service loaded failed failed Netcfg multi-profile daemon
network.target loaded active active Network
The unfortunate thing is that I don't have a /var/log/boot file. Also, because I booted with systemd, I can't use inittab to stop Arch from clearing the terminal before presenting the login prompt.
So, I'm not sure where to go from here. Please give me something to post or read or something. I definitely need to get this to come up reliably at boot, as this'll be a headless unit.

It failed again today:

I don't know what that NOHZ bit is about, but it doesn't seem to stand in the way. So, what I've gathered from all of this is that netcfg recognizes eth0 just fine, but somewhere between systemd's netcfg.service and netcfg-daemon, eth0 is invisible.
Help?

Ipv4 from dhcp, ipv6 static on single interface eth0

Hi,
pls help me understand or solve my problem with my network setup.
I had ipv4 ip address assigned dynamically and ipv6 set statically, both via netcfg and everything worked without problem.
This is my netcfg config:
CONNECTION='ethernet'
DESCRIPTION='A basic dhcp ethernet connection using iproute'
INTERFACE='eth0'
IP='dhcp'
PRE_UP='ethtool -s eth0 wol g'
PRE_DOWN='ethtool -s eth0 wol g'
## for IPv6 autoconfiguration
#IP6='stateless'
## for DHCPv6
IP6='static'
ADDR6=(2002:54f2:xxxx:1::2/64)
GATEWAY6=2002:54f2:xxxx:1::1
But someday I received error when booting up and also when I try to start profile manualy:
/etc/rc.d/net-profiles start
:: eth0 up
RTNETLINK answers: File exists
Adding gateway 2002:54f2:xxxx:1::1 failed
No profile started.
I found that I can't have two gateways on one interface, but until now there's no problem.
When I disabled GATEWAY6 line from config, eth0 profile can be started but ipv6 connectivity didn't works.
I tried set ipv6 to stateless that works, but after some time not more that 5min network connection resets and after recovery in couple of seconds only ipv4 works.
Where's a problem? What can I do to achieve same setup I had before some update last week?
Thanks

houmles wrote:I found that I can't have two gateways on one interface, but until now there's no problem.
I suspect it's a problem with that; I've noticed this problem as well.
When trying to add multiple default gateways with iproute2 (ie, `ip r a default via xxx:xxx:xxx::xxxx`) it errors with the error you've mentioned. I'm not sure if this is a kernel bug, iproute2 bug, or not a bug at all.
Having multiple default IPv4 gateways works fine.
I believe netcfg doesn't check for an existing gateway and delete it first (or use `ip r r` instead or `ip r a`) before adding the one; but I haven't checked the code so I could be wrong.
EDIT:
OK, I couldn't resist looking at the code, and it indeed does a 'dumb' addition of the gateway:
112 if [[ -n "$GATEWAY" ]]; then
113 report_debug ethernet_iproute_up ip route add default via "$GATEWAY" dev "$INTERFACE"
114 if ! ip route add default via "$GATEWAY" dev "$INTERFACE"; then
115 report_iproute "Adding gateway $GATEWAY failed"
116 fi
117 fi
I'm looking at making a patch now. Patch and bug report: https://bugs.archlinux.org/task/29480

Bridge Does Not Automatically Bring Up Photoshop When the Photo is Double-Clicked

I have just purchased CS4 with Bridge for my new MacIntosh. In Bridge for the PC, when I double click a photo it automatically brings up Photoshop. On the Mac version, it gives me an error message saying that part of the application is not loaded. I completely uninstalled the program, and reloaded the application and still get the same message. So in Bridge on the Mac, to get around this, I right click the picture and go to "Open With" and there are two entries: "Open with CS4 (default)" and "Open with CS4." This works if I pick either option. My Windows version only has "Open with CS4 (default)" as the option.
I called Adobe support (in India?) with no solution.
I really like the double click option rather that using the pop-out menu choice. What is wrong with the Mac install, and how can I fix this issue?

Thank you for your help. I updated the software and it "healed" itself.
Best regards,

This might mean that you have either 2 installs of CS4 (one on an other
disk?) or you did not use the the default application folder on root level
but have it installed in the user account application folder. Could you
check this?
and go to "Open With" and there are two entries:

This is not due to malware. There is no known malware capable of infecting any iOS device, unless that device has been jailbroken.
I have seen one other report this morning of a similar issue. This could simply be due to a rogue ad on those sites. However, if it's happening on a number of other sites as well, you may be having some problems with your network. As an example of the sort of thing I'm talking about, see:

Fluids and electronics do not mix.
You have caused some serious damage to parts of your computer, and likely voided the warranty until Apple completes a repair and re-certifies it.
Step one is to turn it off and do NOT (did I say do NOT yet?) turn it on again yourself.
Take it to an Apple store and be prepared for a large repair bill.
Sorry, but that is the truth.

Automatically bring up pdf files in Preview (or at least Safari)

Ideally, I would like the ability to click on a pdf file in Safari and have it automatically bring it up in Preview. I believe you need a plug-in for that and it looks like that doesn't exist (or does it). Assuming that's the case, I would settle for bringing up the pdf in Safari and then doing a ctrl-click to open with Preview. Right now opening a pdf in Safari opens a separate little window which takes more than a few seconds. It used to open up in Safari, but in all my messing around trying to figure this out, that stopped working and I can't figure out how to make it do that again.
Here's my situation and what I've tried so far. First, I have an Intel Mac and don't want to run under Rosetta for performance reasons (things take twice as long!), so Adobe, Shubert's plug-ins, etc. won't work. Adobe is too slow anyways, but I kinda like Shubert's. I've set my default pdf reader for all pdf files to Preview. I've tried turning Adobe's option to use it as the default browser plug-in on and off. I've reinstalled Adobe, removed it and reinstalled it again. I've removed the Adobe plug-in from the Library/Internet Plug-Ins folder and put it back again.
I've tried making this work with every conceivable combination of the above with no luck. Like I said, if I could just get back to having a pdf open in the Safari browser, I could make it work from there to open Preview. But if there's any way to open Preview directly from opening a pdf in Safari, that would be the bomb. Or if anyone knows of any other good pdf browser plug-ins that work with Intel based Macs running safari natively, that would be acceptable too. Spent many hours researching this on the boards as well as trying stuff. Hopefully someone can steer me correctly. Thanks.

Well Starman, I did everything you said to do to reinstall Safari and it still brings up that separate little window as opposed to bringing up the pdf in the browser. The Software Update didn't do anything after reinstalling Safari, so I reinstalled 10.4.8. Still no luck with the pdf.
One interesting thing I tried is that I set Safari so it would run using Rosetta and then set Adobe Acrobat to use the plug-in. When I brought up a pdf, it used the Adobe plug-in, but it still brought it up in a separate window and not within the browser. When running under Rosetta without the Adobe Plug-In turned on, it brought the pdf up in the separate little window again, but not the Adobe Plug-In - similar to when not running under Rosetta.
Now a few days ago I did download the Shubert Plug-In and turned Rosetta on so I could check it out. It brought up that plug-in in that little window. Now I'm not sure of this, but I think that was the first time that little window came up and I haven't been able to get rid of it since. I trashed the Shubert Plug-In, but could it be possible that something from that is hanging out there causing this problem? Or?

My screensaver won't automatically bring up pictures from my iphoto albums as it always did in the past since I installed Mountain Lion. I do use an external hard drive to save all my pictures and music on that is always connected to my MacBookPro. Any suggestions what I may be doing wrong.

How do I automatically bring up the login window?

I'd like to be able to automatically bring up the login window, or automatically fast user switch to a non password protected account.
Basically, I have a computer with an account for me and one for my wife, and I'd like one for my daughter that will have parental controls implemented. I'd like to be able to have that account become active automatically if we leave either of the adult accounts idle for a while.
I would have thought I could do this easily with Automator or Applescript, but I can't figure out how.
I can't just use the built in "all log out" function in the Security pane because I have things running in the background under my account - so my account must remain logged in.
Any thoughts? TIA!

The easiest thing to do would probably be to turn on 'Require Password when waking from sleep' in the Security preference pane.
Then, when someone goes back to the computer, it'll show a password input screen, but if you have FUS turned on, it will also have a 'Switch User' button that will take you back to the login screen.

The instance is using interface 'eth0' of type 'Unknown'.

Hello,
I've installed an oracle cluster 10.2.0.1.0 with two computer successfully.
The two computer are SUSE linux ; "uname -a" display
Linux dbprod1 2.6.13-15.8-smp #1 SMP Tue Feb 7 11:07:24 UTC 2006 x86_64
x86_64 x86_64 GNU/Linux
After a month I was obliged to change the subnet of eth0. So i must change the
addresses of the 2 machines and the 2 VIP address.
With the utility oifcfg I correct the information about the interface eth0. (I
execute also vipca)
oifcfg iflist
eth0 10.23.11.0
eth1 10.25.13.0
oifcfg getif
eth0 10.23.11.0 global public
eth1 10.25.13.0 global cluster_interconnect
Now in the EM I obtain this two warnings (one for each instance):
mbprod_mbprod2: Interconnect; Interface Type;The instance is using interface
'eth0' of type 'Unknown'.
mbprod_mbprod1:Interconnect; Interface Type; The instance is using interface
'eth0' of type 'Unknown'.
How can I correct the problem?
Thank you very much.

Suppose we are using interface, to use the method declared in the interface, which is implemented in another class. Now what is the difference between using the interface instead of directly instantiating the implemented class to use the method. Can anyone explain me in detail.To use an interface an implementing class must be instantiated somewhere (though not necessarilly in your own code). The object in question is accessed through the interface, but in reality every Object is an instance of a concrete class. For example say you connect to a database. DriverManager gives you an object which implements java.sql.Connection. The object you get will actulay be of a class defined inside the database provider's libraries and which you may well not be allowed to instanciate yourself, all you need to know is that it implements Connection. And because you handle it as a reference to Connection, you don't need to care what the actual class is, you can change the database URL and switch to a completely different database driver without changing your code.
