• dhcpcd: DHCPv6 REPLY: No addresses available for this interface.


    So recently I’ve been getting problems with dhcpcd, which I never had before and seem to have randomly sprung up. It either means my connection is intermittent or totally unusable. Interestingly, when I run killall on dhcpcd, the page I’m trying to load loads instantly.

    I’m not entirely sure the purpose of dhcpcd but since it is in Arch’s base repo, I assumed it was important. Does anyone know why this is happening?

    [[email protected] ~]$ sudo dhcpcd wlp2s0
    DUID 00:01:00:01:21:7b:41:64:74:29:af:2a:5b:93

    wlp2s0: adding default route via 172.30.128.1
    forked to background, child pid 10006
    

    When I run journalctl -xe, I get this:

    Oct 25 13:13:35 pc dhcpcd[10006]: wlp2s0: DHCPv6 REPLY: No addresses available for this interface.
    Oct 25 13:13:35 pc dhcpcd[10006]: wlp2s0: DHCPv6 REPLY: No addresses available for this interface.
    

    It’s probably worth noting I’ve had problems with my network card before, it’s a realtek network card (my friend has similar problems).

    No addresses available for this interface

    You have dhcpcd enabled ?

    systemctl enable dhcpcd.service and
    systemctl enable NetworkManager.service

    and restarting…

  • @judd Yeah, I’ve tried that but doesn’t seem to fix anything.

  • ok

    lspci -k -nn | grep -A 3 -i net

    # wifi-menu wlp2s0 ?

    I’m not entirely sure the purpose of dhcpcd

    DHCP is Dynamic Host Configuration Protocol. It is responsible for assigning IP addresses automatically when you plug in network devices. In most cases IPv6 is not necessary and can be disabled if causing problems.

    ipv6

    not 100% right, as a lot of new router devices sing it by default, now, but true that it can be disabled if it causes problems, epending on what is aviable to get internet access, mostly there should be a ipv4 fallback, also if ipv6 is used.

  • What is the status of dhcpcd even though it is enabled …

    sudo systemctl status dhcpcd.service

  • @judd said in dhcpcd: DHCPv6 REPLY: No addresses available for this interface.:

    systemctl status dhcpcd.service

    do not need root rights and can be run as user… but no need for it if you are using:
    NetworkManager.service

    systemctl status NetworkManager.service

  • I do not see anything that is out of the ordinary, supplicant scanea and authentic … well, I do not know why the flashing …

    Is your connection still intermittent?
