Netctl: Using netctl-ifplugd and netctl-auto simultaneously?

Hi! I've recently been having difficulties with Wicd, and have decided to try replacing it netctl. I've already got working profiles, but one thing that I would like to have working is multiple-interface automatic connection. As it is now (having both services enabled) a race condition exists, where one interface may hijack the default route, have no default route if one of them disconnects, or have a gateway conflict where no IP or Route is assigned to the interface.
I have two profiles for my home network, and I'd like to be able to use ethernet while at my desk and wireless while moving about the house. I'm currently dealing with this by leaving -ifplugd enabled, and only enabling -auto if I need to use a wireless connection, then disabling it before I reconnect to wired.
Is there a better, and more automated way of dealing with this situation?
Thanks in advance.

djo: The issue with that in my situation is that I require a static IP, and my locked-down Comcast gateway's pseudo-static DHCP option is extremely buggy. As crappy as it is, it does the job well enough to not warrant a separate router, especially since most of the good ones that support OpenWRT are quite pricey. I haven't really found a solution to the original problem, and still employ my original workaround, since entering my password once isn't much of an inconvenience.
Šaran: Well they're both in the subnet, and can automatically connect at the same time. Both are supposed to be used as my machine's default route, so things get kinda wonky when two interfaces are connected to the same network fighting over who gets to provide the default route. Since your situation has only one interface that needs to serve the machine's default gateway, you don't run into that problem when both of them are trying to connect/disconnect at the same time.
WonderWoofy: I was actually messing around with this as a possible solution when I first posted the problem. If I remember correctly, I couldn't manage to get it to play nicely, but I'll give it another shot in the morning to see if I can figure it out. I'd only messed with the ExecUp/ExecDown options, but hooks actually look like a far better candidate to solve this issue (as well as re-implementing some of my wicd-scripts.)

  • How can I use web-console and element inspector simultaneously in Firefox 20+ as I could in Firefox 19-?

    Yes, new web-developer all-in-one tools are total mess.
    I didn't find the answer to this question either https://support.mozilla.org/en-US/questions/955612 but downgrade to Firefox 19.
    But nor in Nightly, nor in Aurora, nor in Firefox Beta, nor in Firefox 20.0 I can use simultaneously web-console (where I test some style changing javascript code) and element inspector (where I instantly observe a reaction to my code). The only option I see is to switch every three seconds between them. How can I fix this except downgrading?

    You can consider to use the DOM Inspector extension instead of the built-in Inspector.

  • Using nic nas and usb internet simultaneously

    i use my nic card to connect to a nas.  i use a usb device for internet.
    both work simultaneously on my pc and worked on my older g4 which both were connected to a router and were able to also share pc-pc.
    i now have a g5 (ppc) and cannot get the nic/nas and usb internet device to work at the same time.
    I reassigned device order with ethernet ontop (worked on the g4) and it doesn't work.  I have to constantly turn one device off and the other on and vice versa for which device i need to use at that time.
    how can this be resolved please...it's very frustrating.
    thanks.

    The Interface that connects to the Internet, needs to be drug to the top of System Preferences>Network>Show:>Network Port Configurations and checked ON.
    10.5.x/10.6.x instructions...
    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
    The interface that connects to the Internet should be dragged to the top of the list.

    Hello I want to write files to this wireless stick from a PC connected via USB and at same time wireless stick is streaming another file to some other device.  Is this use case scenario possible in this product ?Thanks 

    Hello, Yes this feature for now is possible when you connect the wireless tick to the pc via usb and then use a ios device to access it wirelessly and access the files with the app. Unfortunatelly it is not working while plugged on the usb port with an android device.

  • HP Color LaserJet CP2025dn Printer Wired Connectivity and have USB simultaneously?

    Hello to all;
    Thank you in advance.
    I have a HP Color LaserJet CP2025dn Printer. 
    The question, can I use ethernet connection and have USB simultaneously?  Ethernet is faster, right?
    Currently, I have the printer connected to network via Ethernet Wired Connectivity through an Apple Aiirport Extreme base station.  I have several Mac's all operating under 10.9.1, and two PC's (one is WIN XP, and the other WIN 8.1), which all operate fine with 2008 wired/wireless technology. I know what a dinosour. I am in the process of upgrading the household to current wireless technology with a NetGear AC1900 Nighthawk Smart WiFi Router (Model: R7000), 802.11ac Dual Band Gigabit, with two USB ports ((1) 2.0 and (1) 3.0) . I connected the printer directly into the Netgrar router, and it wouldn't print, ran setup through the Mac and Win computers and still wouldnt pring. One of the reasons that sold me on the Netgear router was the ReadySHARE® USB access—Wirelessly access & share. In order for me to utilize the ReadySHARE® feature is to connect via a USB cable.  Sob story, the longest USB cable off the shelf usually 16",  and to reach where the printer is now, I need @25-28 feet of cable. Is ther a maximum length of USB that I can use with out suffering loss of speed/functionality?
    Again thank you for your time

    I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/

  • Am I able to use both Carbonite and Time Machine as back-ups for my iMac?

    HI,
    I have a iMac, and I have recently recently completed the initial back up for Carbonite. I also have a 2TB Seagate external hard drive that I would like to use with Time Machine. I am wondering if I am able to use both Carbonite and Time Machine simultaneously.

    Hi, and welcome to the forums.
    As bdmarsha says, yes, you can run both simultaneously.
    But one caution; there are some reports here that some of the online backup apps keep some fairly large, frequently-changing files on your system. Time Machine will back them up along with everything else, which can take some extra time and space on your TM drive.
    After your initial TM backup, see how large the incremental backups are (by watching the progress bar and info on the +Time Machine Preferences+ window). If those seem too large for the changes you've made since the previous backup, see #A2 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum), for a couple of apps that will show exactly what was backed-up.
    If you find such things, you can exclude them from TM backups, per #10 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

  • Netctl-auto and dropbox

    Hi, I've been reading the wiki. The only difference is my interface name is wlp2s0 instead of wlan0. So I went to /etc/netctl/interfaces and I created a new file called wlp2s0 with the contents
    ExecUpPost="su -c 'DISPLAY=:0 /usr/bin/dropboxd &' root || true"
    ExecDownPre="killall dropbox"
    However, this doesn't seem to do anything. I've disabled the "Start Dropbox on system startup" option, but everytime I restart, there's no dropbox icon in the dock like there normally is. What am I doing wrong?
    Internet roaming still seems to work, even after putting the computer to sleep.

  • Netctl-auto & netctl-ifplugd prefer wired?

    Hi,
    On my laptop running Arch Linux I've got both netctl-auto and netctl-ifplugd running. I have both ethernet and wireless set up in my house, and I'd like to have it set up so that it prefers wired over the wireless connection. So that if it's plugged in I can know for sure it is using the wired connection and not the wireless connection, and if I unplug it it should switch to wireless.
    There's a 'priority' variable but that only applies to wireless connections and so it has no effect on the wired profile. I've gone through the manpages for netctl-auto and ifplugd and gone through the relevant sections for netcl in the wiki multiple times but there doesn't seem to be anything on getting this kind of setup.
    So is there a way to have Arch prefer wired connections over wireless?

  • [SOLVED] netctl-auto not working, and I cannot remove netctl instance

    Hi, I installed Arch a few days ago, netctl-auto was working yesterday but today it's not.
    Note that
    netctl start
    works: I have a problem with netctl-auto only.
    $ ping -c 3 8.8.8.8
    connect: Network in unreachable
    I have created only one netctl profile so far, it's called wlp4s0-VM581389-2G (wlp4s0 is the name of my wireless interface)
    $ ls /etc/netctl
    examples hooks interfaces wlp4s0-VM581389-2G
    $ netctl list
    wlp4s0-VM581389-2G
    wpa_actiond is installed, and I have done
    systemctl enable [email protected]
    But for some reason I have some extra netctl@ instances that shouldn't be there. I am wondering if they could be the cause of netctl-auto not working properly:
    $ systemctl | grep netctl

    - What are these bullet points at the beginning of these two lines?
    - Where do netctl@my\x2dnetwork.service and netctl@wlp4s0\x2dVM581389\x2d2G.service come from? They might be instances that I had enabled in the past.
    These instances are not enabled and they are inactive, but they are loaded!

    I have tried to get rid of them, but not managed:

    Also, I have tried to check with
    netctl-auto list
    , which gives an empty output. I am guessing that it's normal, because the netctl-auto instances are managed by systemd?
    Now, trying to understand what is happening to [email protected]: as seen before with systemctl | grep netctl, it is active and running.
    Then I do:
    $ journalctl -u [email protected]

    What does this mean? Which file might have been left by an unclean termination? I tried to find this info in the wpa_supplicant documentation, and by searching on Google, but couldn't find anything.

    - where can I investigate next, to get netctl-auto@wlp4s0 to work?
    Any help greatly appreciated :-)

    What is the output of:
    ls -l /etc/systemd/system/multi-user.target.wants
    netctl-auto cannot be used with explicitly enabled profiles (ie, those for which you have used `netctl enable <profile>`).

  • Netctl profile works flawlessly unless called by netctl-auto

    I have four wireless profiles in /etc/netctl and all of them work just fine when used manually, i.e. netctl enable <profile> or netctl start <profile>, but when I set up netctl-auto one of them keeps failing.
    The three others are identical except for the SSID and the WPA key so I'm including just one of them here along with the one the keeps failing, but there's really nothing special here. The only difference is that the one that keeps failing has a hidden SSID.
    One of the three which work:
    Description='WiFi: AMPERSAND'
    Interface=wlan0
    Connection=wireless
    Security=wpa
    IP=dhcp
    ESSID='ampersand'
    # Prepend hexadecimal keys with \"
    # If your key starts with ", write it as '""<key>"'
    # See also: the section on special quoting rules in netctl.profile(5)
    Key='0f20f8g0fg2'
    # Uncomment this if your ssid is hidden
    #Hidden=yes
    The one that doesn't:
    Description='WiFi: HANLUKIO'
    Interface=wlan0
    Connection=wireless
    Security=wpa
    IP=dhcp
    ESSID='kjKJls83jpkskKkkUyasjqKAS'
    # Prepend hexadecimal keys with \"
    # If your key starts with ", write it as '""<key>"'
    # See also: the section on special quoting rules in netctl.profile(5)
    Key='CCyzJvIVljL9hsHSbhspPhs929c0hLssh38sPssofo382d8OS320dgSop3hfIGdi32GF'
    # Uncomment this if your ssid is hidden
    Hidden=yes
    The wiki doesn't seem to mention anything specific concerning a hidden SSID and netctl-auto, and since all four work flawlessly when used manually, I'm out of ideas. I'll try setting $NETCTL_DEBUG on the next try and hopefully that will output something meaningful but that wont be till next week and I was curious if anyone knew off the bat what the issue might me.

    As I understand man netctl.special, the netctl-auto does not honor the WPADriver parameters in the profiles, because it works on the interface level. Hence, the "Hidden=yes" is not parsed and the hidden ones are probably discarded.
    You should be able to add the parameter "scan_ssid=1" (or "Hidden=yes" - not sure) to a hook for the interface in /etc/netctl/interfaces/
    edit: wrong semantics striked; see below.

  • Netctl-auto cannot connect after unblocking wifi

    Hello,
    I'm using netctl as a connection manager. Systemd automatically starts "netctl-auto@wlp1s0" and if I boot system with wifi unblocked (rfkill) it is working fine. But when I boot my system with wifi blocked (from previous session) and after boot I manually unblock it (using rfkill unblock wifi), it doesn't pick up network. And when I try "sudo netctl-auto swtich-to <network_name> it prints out:
    WPA association/authentication failed for interface 'wlp1s0'
    It also happens when I'm working without connection with blocked wifi (for saving the battery) and then I turn wifi on - it also doesn't pick up a network.
    I have to first do:
    systemctl restart netctl-auto@wlp1s0
    which blocks wifi (when I try rfkill list, I can see that this restart blocked it) and only if I immediately switch wifi on (also using rfkill), it connect as usual.
    Does anyone experience same issue? Is it normal behaviour? Thanks

    I think you are seeing a manifestation of this bug.
    Note that I wrote that report.

  • Netctl-auto@wlp3s0.service broken after wpa_supplicant upgrade

    A few hours ago, I upgraded from wpa_supplicant-2.3-1 to wpa_supplicant-2.4-1. Subsequently [email protected] stopped working. After I started it, it would be reported as "active (running)" but fail to connect to any WIFI network (I wouldn't get assigned a DHCP IP address):

    Notice the "Could not read interface...". I downgraded back to 2.3-1 and the problem went away. Could this be a wpa_supplicant bug (new bug in 2.4-1) or netctl bug (incompatibility with the new wpa_supplicant)?
    There's nothing special about the profile files in /etc/netctl. In addition to the ones for wired network, I have a few files named like "wlp3s0-XXX" and they look like this (password crossed out):
    Connection=wireless
    Description='Edward'
    Interface=wlp3s0
    Security=wpa
    ESSID='Edward'
    Key='????'
    Hidden=yes
    IP=dhcp

    I'm having exactly the same problem.

    This also break wifi-menu by the way, so the only option now is trying a manual wpa_supplicant connect. I should mention that this morning (after troubleshooting all night with no result) I managed to connect to my AP once (while begin connected via ethernet as well). After disconnecting the ethernet cable and trying again it failed again. I have not been able to reproduce this.
