[solved] network interface names changed?

Hi,
I reinstalled arch on my laptop yesterday (hard drive failure). Normally, not to big a deal. Took me four hours to get arch installed. Why? couldn't for the life of me figure out how to get the wireless connected (ethernet connection unavailable, port is physically damaged). In the end, my fault, I should have tried iwconfig earlier.
It seems that my network interfaces have all changed names since the last time i installed. The wireless interface has changed from the sensible 'wlan0' to the mystical 'wlp4s0'.
also, eth0 is now enp9s0.
This has messed up a number of my scripts and above all is more than a little confusing, wlan0 feels right, wlp4s0 feels wrong.
Now, I'm not opposed to change. I like change, even if it breaks a lot of my scripts, but I like to know why something has changed to something less intuitive.
Why was this change put in place? I can't find any real info on it after 30 mins googling.
Can it be changed back through some setting somewhere without upsetting whatever problem it's supposed to fix?

Yes you should have just searched for "Welcome to Arch!".

[SOLVED] Network interface name keeps changing

My network interface name keeps changing between wlp2s0 and wlan0. This is a real pain, since I never know what name will be generated at boot. Most of the time it's called wlp2s0, so this is what netctl is set up to handle by itself. At boots were wlan0 is generated I have to connect manually.
I've tried making the name static by adding a rule to the /etc/udev/rules.d/10-network.rules. The rule i added was:
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="48:5d:60:7e:64:e9", NAME="wlp2s0"
Wlp2s0 is generated at boot alright, but I still have to connect manually with this solution. As if the "new" wlp2s0 is not recognized as the old one (same MAC). What gives?
This is on an Asus Eee 1001PXD, with the Qualcomm Atheros AR9285.

I've now been able to replicate the issue, and run the command:
journalctl -b
I did find the output:
mai 18 02:30:02 <hostname> systemd-udevd[126]: error changing net interface name wlan0 to wlp2s0: Device or resource busy
I haven't been able to process the whole output yet (I'll continue tomorrow if necessary), but I've found some things that I hope will clearify things. I get similar outputs to the following a lot throughout:
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: carrier lost
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: waiting for carrier
mai 18 02:30:04 <hostname> systemd[1]: [email protected]: control process exited, code=exited status=1
mai 18 02:30:04 <hostname> systemd[1]: Failed to start Automatic wireless network connection using netctl profiles.
mai 18 02:30:04 <hostname> systemd[1]: Unit [email protected] entered failed state.
mai 18 02:30:04 <hostname> systemd[1]: Starting Network.
mai 18 02:30:04 <hostname> systemd[1]: Reached target Network.
EDIT:
I see now that this is later in time, so that's not so strange after all. I'll look some more.
EDIT2:
The error code that a name change i impossible is the first time the term 'wlan0' occurs in the log. However there's a line much earlier that talks about wlp2s0:
mai 18 02:29:59 <hostname> systemd[1]: Expecting device sys-subsystem-net-devices-wlp2s0.device...
But as I said, if this information doesn't help, I'll have a closer look at the output tomorrow. Getting late here in Norway now.

How to get active network interface name?

Hi All,
Can any one tell me how to get the currently active network interface name (Local Area Connection/ Wireless Network Connection/ other) either by using java SDK or win32 API.
Is there any function to get the active network interface name in java/win32?
Is there any procedure for it to get from observing registry keys.
I found NetworkInterface class in java but not yet succesful in getting the display name of active network interface.
Can anyone help me with partial code?
Please help me.

Use getLocalHost() then retreive the list of NetworkInterfaces and cycle through them until you find the one that has that address.

[Solved] Network interfaces change places after every reboot.

This has been bugging me for a while, it seems that in Arch every time the system reboots, the network interfaces are recognized in a random order.
So what was eth0 in the last reboot will be eth1 in this reboot, and sometimes it will remain for several reboots and then flip again.
This does not occur in Fedora on the same machine ever.., does any one know how to work around this problem?

I meant why is 75-persistent-net-generator.rules.optional optional? or why for example on Fedora this is never an issue?

[SOLVED] Network interface enp2s0 no longer detected

Hello,
Yesterday after rebooting, right after Grub, systemd-fsck does its stuff (clearing blocks, etc...) then nothing.
After a quick research I've found that removing "quiet" from the Grub command line would allow more messages to be displayed, which was quite helpful.
This is in fact not a partition mounting problem, here is what I have:
[ OK ] Started Accounts Service.
[ TIME ] Time out waiting for device sys-subsytem-net-devices-enp2s0.device
[ DEPEND ] Dependency failed for dhcpcd on enp2s0.
[ OK ] Reached target Multi-User System.
[ OK ] Reached target Graphical Interface.
I obviously have a networking problem (and probably a "Graphical Interface" or Nvidia related thing problem), so I log in another console, and after doing ip link list, I only have the loopback listed, no enp2s0 or WiFi interface, for some reason they are no longer detected.
I've run the live version of Arch to mount and arch-chroot my partitions, not to mention my network interfaces are detected and I can upgrade things with pacman, I've tried to disable dhcpcd on enp2s0 to avoid the time out thing, and while I can say it does what it's supposed to do, it doesn't solve anything anyway since I'm still stuck at Reached target Graphical Interface. (and don't have any network access, to state the obvious).
I've even thought about a Kernel/Driver problem after an update, but I'm not sure, any idea or some log I can have a look at ?
Thank you for your time.

Oracle restart: change network interface name

Hi all,
Env: Oracle Restart 11.2.0.3 w/ASM.
I've been trying to look up info about this without any luck so I hope some experts here can shed some light..
To improve redundancy we're planning to change the network configuration in our Oracle Restart environment from using 1 LAN interface to a bonded interface consisting of 2 interfaces.
So the change will be from using "eth0" to using "bond0" consisting of "eth0" and "eth1". Are there any changes that must be done in the Oracle Restart configuration to reflect these changes?
Thank you for your time.

[SOLVED] systemd-udevd renames network interfaces

During install I enabled dhcpcd service like this:
systemctl enable [email protected]
Seems perfectly valid, eh? But after reboot network I've got the following messages:
[ TIME ] Timed out waiting for device sys-subsystem-net-devices-eth0.device.
[DEPEND] Dependency failed for dhcpcd on eth0.
dmesg | less
systemd-udevd[111]: renamed network interface eth0 to enp0s3
It appears systemd changes network interface names. But then I suppose [email protected] is to be removed:
[Unit]
Description=dhcpcd on %I
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

old to Linux new to archLinux
jasonwryan -thanks!
Your post helped me figure it out why my Ethernet interface name was changed to enp0s3 and why - I like the old naming convention ethx easier for me to remember. So went the route with custom rules in /etc/udev/rules.d
Here is what I used.
70-my-net-names.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="08:00:27:3b:f3:cd", NAME="eth0"

Changing a Network Interface in DAG Replication Network after going P2V

I have a DAG member suffering severe hardware failure so I have gone P2V with it. It's functioning fine, except that the DAG Network Interfaces have changed - The MAPI Interface was on "Local Area Network" on the physical server, and is now
on Local Area Connection 7 on the VM. However, the DAG settings still point to "Local Area Network" and will not let me change it. Same thing for the replication network.
I have lost redundancy due to this, so I need to get it repaired pretty promptly.
Removing and re-adding the subnet in the DAG network has no effect - it still references the old physical NIC instead of the new virtual NIC, despite the new virtual NIC having the same IP as the old physical NIC.

Try to change the network binding on the server
http://technet.microsoft.com/en-us/library/cc732472(WS.10).aspx
Try to delete the hidden network adapters as well.
Open Device Manager, from the File menu, expand the View and select the Show Hidden Devices option. This will enable and show any old un-used devices in the window

No network interfaces showing

Hello everyone. I have been using arch linux for a few months now and loving it, except for one weirdly persistent problem with my wireless. In fact this is the third time it has happened to me and have been unable to fix it. The last two times I simply reinstalled arch after failure of any progress but that is very tedious, timewasting and most important unnecessary, so I am calling upon the arch-linux forum for help.
Basically my problem is this, I have been using wifi-menu to connect to my wireless network since I got arch and everything was going smoothly, no problems at all, until one day I booted up my computer and was unable to find any connections what so ever. At first I thought it was just my router crashing or something but everyone else was able to connect fine so I ran the command iw dev and was surprised to see that there was no output. It had discovered no connections or interfaces at all, not just my personal connection had dissapeared but so had all of my neighbours. I tried plugging in an ethernet cable to my laptop but was unable to receive any connection from that either. It may be helpful to note that in the past the interface for my wireless connections changed at random. It changed from wlp2s0 to wlo1.
Here are somethings that I have tried doing recently to fix the problem.
Although I doubted it would help me as my problem seems to be that I have no wireless interfaces available, I had heard that having multiple packages, e.g dhpcd and netctl, handling your connection at once can cause conflicts. I tried disabling all dhpcd services running because I believe netctl is what wifi-menu uses. Here is the current states of my services from the command systemctl list-unit-files.

I also tried disabling netctl@(my profile).service and left netctl@(my other profile).service (I have multiple profiles from when my interface name changed) enabled to make sure there were no conflicts there. Just so you know when my problem occurred neither wireless connections were enabled at the time. As I said I was using wifi-menu to manually connect after start up.
The only thing I have read about solutions similar to my problem is the mention of getting wireless drivers in the arch-wiki but I already have broadcom-wl drivers installed(although I may not have set them up this time over as they were not active meaning I was probably using broadcom brcmsmac/brcmfmac or b43). I thought that possibly my the drivers had somehow been disabled and when I checked with lsmod | grep broadcom nothing came up. I then loaded the module with sudo modprobe broadcom. Now lsmod | grep broadcom returns two results.

I find it odd that this is happening to me on arch linux only. My windows 8 is fine (I have a dual boot) and even when I used Manjaro over the course of a couple of months, which is based on arch, it worked fine for me. I was using wicd on Manjaro and am thinking of using that next time for arch. It is also important to remember that it's not only my wireless that's not working, neither is my wired connection.
Any help would be appreciated. I have no idea what to do to fix it and can not find any reports of similar problems happening to anyone else. I really want to get back to linux. My productivity has dropped alot since I have been using Windows 8. If you need me to post the output of any commands just say and I will do so. Once again thank you for any help.

Haha yea I'm sure.
Yea I know but I could never get it to work. Then again I haven't used wired on arch before.

Error in udev change of net interface name wlan0 to wlp3s0

My quite fresh installation of Arch has started having the following problem:
the udev rename of my wireless interface from wlan0 to wlp3s0 suddenly stopped working!
In journalctl, I find the following error line:
Jan 09 16:23:43 mole systemd-udevd[180]: error changing net interface name wlan0 to wlp3s0: Device or resource busy
I am using netctl, netctl-auto and netctl-plugd with wpa-supplicant and dhcpd. The issue seems to be that netctl tries to do stuff with wlan0 before udev can rename it, as a non-predictable race condition. Further down in journal, I have this (non-error) line
Jan 09 16:23:43 mole systemd[1]: Started (Re)store the netctl profile state.
Searching Google yielded me a few places talking about this, but no solution as I could see, and they were also possibly quite outdated.
My ethernet interface is properly renamed and works without issues. I should perhaps also mention that my install is now about 3 weeks old, and I have rebooted the machin a number of times before this behaviour started. In this time I also switched from netctl to wicd back to netctl, and the last switch was only a few days ago.
I have brainlessly tried various stuff, such as disabling netctl-auto and netctl-plugd for all interfaces, as well as adding a custom renaming rule to
/etc/udev/rules.d/10-network.rules
. Needless to say, this didn't resolve my problem.
In case it is important, I have the following services pertaining to networking running:
UNIT LOAD ACTIVE SUB DESCRIPTION
dhcpcd.service loaded active running dhcpcd on all interfaces
[email protected] loaded failed failed Automatic wireless network connection using netctl profiles
[email protected] loaded active running Automatic wired network connection using netctl profiles
netctl.service loaded active exited (Re)store the netctl profile state
netctl@wlan0_eduroam.service loaded active exited Networking for netctl profile wlan0_eduroam
polkit.service loaded active running Authorization Manager
systemd-udev-trigger.service loaded active exited udev Coldplug all Devices
systemd-udevd.service loaded active running udev Kernel Device Manager
systemd-update-utmp.service loaded active exited Update UTMP about System Reboot/Shutdown
wpa_supplicant.service loaded active running WPA supplicant
Is it right to have netctl.service activated?
Any help is greatly appreciated.
Thanks,

Thanks for the reply, lspci. With the same no. as your question:
1. Right now I have both wlp3s0_[some interfaces] and wlan0_[same interfaces] since I need both interfaces. All of the names are correct, and their configs are the same expect of course for the Interface-line. I also have an enp0s25_dhcp for my wired connection.
2. and 3. The custom udev rule that I made after the problem started occurring is in /etc/udev/rules.d/10-network.rules and contains
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="a4:4e:31:cd:5d:64", NAME="wlp3s0"
I can't seem to detect that it has any influence or is even run. But on the other hand, it is exactly this that udev was already trying to do but failing.
4. I could of course do this. But shouldn't it work without conflicting with the udev rename? The wiki currently recommends exactly these two services.
Right now my system works, albeit more manually than I would hope. I am on wireless right now, but if I lose connection (bad reception here), then I have to stop the netctl service on wlan0, down the wlan0 link and then restart netctl on wlan0. Also, whenever switching wireless network or to wired, I expect to have to do similar tedious stuff.

The name of network card is changing

Hello,
I have network card and wifi card in my notebook. I have updated udev, kernel, firefox etc. Since time the name of network card is changing. Sometimes lan is eth1 and wlan is eth0 and sometimes lan is eth0 and wlan is eth1.
It s problem for me. Becouse I dont use dhcp.
Any sugestions.

I gave this a shot and I'm still haveing the same problems.
This is my /etc/udev/rules.d/netdevices.rules:
KERNEL="eth*", SYSFS{address}="00:0d:56:b3:52:fc", NAME="eth0"
KERNEL="eth*", SYSFS{address}="00:0e:35:40:91:77", NAME="eth1"
Output from ifconfig (just to show names and macs...
eth0 Link encap:Ethernet HWaddr 00:0E:35:40:91:77
eth1 Link encap:Ethernet HWaddr 00:0D:56:B3:52:FC
It seems that udev just ignores the custom rules and its potluck on whether it comes up with the right names or not. I have another custom rule file in there as well which changes various usb cameras and stick drives into more meaning full names other then sd?1, those rules seem to be ignored as well.
[edit]Solved!
The following netdevices.rules works:
KERNEL=="eth*", SYSFS{address}=="00:0d:56:b3:52:fc", NAME="eth0"
KERNEL=="eth*", SYSFS{address}=="00:0e:35:40:91:77", NAME="eth1"
It seems that you have to use "==" in comparison operations. Did this used to be the case? I don't remember having to use them before and most examples I see use a "=" for both comparison and assignment. Did they change the rules syntax for the new version or maybe just correct an error that allowed "=" to work as "=="?

[SOLVED]Linux 3.10.6 fails to detect network interfaces, input devices

I upgraded my ASUS laptop to Linux 3.10.6 and I can no longer use my mouse or keyboard in a desktop environment. A USB mouse faired no better. The keyboard works in console mode. I've done a couple reboots and a good deal of searching online, but no one seems to have the same problem. My first inclination was that udev was no longer running, but a quick "ps -aux | grep udev" revealed that systemd-udevd was running, but not udev itself. Is it safe to start it manually? My network interfaces have also disappeared, BTW, and the font size in console mode has also changed (size has increased, font is fuzzier). Any ideas?
EDIT: I do have the loopback interface.
lsmod shows:
ext4
crc16
mbcache
jbd2
hid_multitouch
hid_generic
usbhid
hid
sd_mod
ahci
libahci
libata
ehci_pci

Does your running kernel match what pacman has installed? Do uname -r and compare that against the version of pacman -Q linux. If they are different, reboot.

USB wireless adapter - interface name keeps changing

I have used different usb wireless (G) adapters with my 12" Powerbook G4.
Each was automatically assigned an interface name (BSD) such as en2, en4.
I recently updated to a Wireless N dongle (D-Link DWA140) which works great with my new Belkin Wireless N router.
I have had a few connection problems where the dongle was named as enNull.
After rebooting and re-entering the ip address via DHCP, I noticed that the same dongle has been renamed each time e.g First as en5 then en6, 7 and 8. It's now called en10
It works fine but is it possible to reset the name/number of this wireless adaptor using something like ifconfig in the shell Or some other way. I understand that en0 is built-in ethernet and en1 is Airport. I have 2 other dongles which are still identified as en 2 and en4. But my current dongle has an inflation problem and I would like to reset it if possible to a lower number.
Is this possible or am I mad to even consider it?
any help welcome.

That is very strange that PCI cards would keep changing names between reboots. Maybe you should investigate that to figure out what's going on. Check the dmesg and journalctl after each reboot and see what the interface is named as. Maybe that will give you some clues as to what "external" program is responsible in naming the interfaces.

Network share name keeps changing

I have setup my eMac to have the network share name eMac but it keeps changing into +eMac (2)+ does anyone know why?

well I do, but a short while later.
or some weeks or even month later, I can do it again.
this is a problem because I need to connect to it from my server.
the server is a Dell PowerEdge 1650 (I know, old, but it was cheap and it does the trick) which is running Linux Ubuntu Server 9.10 "Karmic Koala", since it's a server I did not install a DE(desktop environment) so I need to use the bash or shell (depending on what I do, since it has both)
how I connect it like this (on the sever):
+mount -t nfs "emac.local:/dev/macintosh HD" /storage/nfs/emac/+
the problem here: I use a DHCP, with DHCP reservation.
since I use DHCP reservation the IP should not change.
but the DHCP reservation doesn't really work correctly,
because of this, if my mac is offline (A.K.A off, I never disconnect it), the IP is in the pool, and thus can be assigned to a other computer.
since the IP may change depending on if it is on at a given time.
I need a way to always successfully identify my emac.
for this I use the network name.
and now it changes too!
which means that in order to find it I need to know if it still has the same network name, or what it's IP is.
I can find the IP from a web browser since it's my router who is my DHCP.
but the server doesn't have one.
so I'd have to use a other computer, since the router doesn't allow SSH/TELNET connections.

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.
