Could anyone help with getting an IPv6 address configured on my hosthatch VPS?

I have a hosthatch vps and have requested IPv6. In the web interface for my VPS, I see an IPv6 Block and clicked the + so an IPv6 address is showing.

I've configured that address/mask and the default gateway on my CentOS 7 system, but whenever I try a ping6, I don't get any response, even from the default GW.

    Not sure it's been said before, but have you tried contacting HostHatch?

    I have not created a single thread. Verify it if you dare.

    Haha, don’t bother to contact your provide as LET support is 100 times faster and you be able to write a negative feedback about your provider as they not be able to guess your issue on your VPS account. :smiley:

  • @skidmark - just for the lulz, let's check result of ip -6 route and compare notes.

    What is the location of your HostHatch VPS?

    But yeah, you should reach out to support - even though they may take a day or two to reply ;)

  • thedp said: /etc/network/interfaces

    except OP is dealing with centOS not Debian so I dunno ... might be something more to do with /etc/sysconfig/network-scripts/ifcfg-eth0 - possibly "properly" setup via nmcli (not sure, I don't mess with centOS very much)

    more general point to be aware of is - I've noticed IPv6 setup can be a bit fiddly if expecting all the bits to fall into place from config when booting - so sometimes might have an 'ifup' clause that works better to set gateway in the /etc/network/interfaces (or whatever). And different providers have various IPv6 setups so it hasn't been obvious (to me at least) what the "canonical" universally correct way is.

    what I often do when in doubt is install from a provider's template for debugging, then for future reference make note of the network configs once all that's working.

  • Is this a machine with local networking? Perhaps you put it on the wrong interface?

    The VPS has eth0 and lo, I added the address on eth0. Not sure what local networking is.

  • ifconfig shows the address correctly under eth0, but the default gw is not reachable with ping6. IPv4 is working properly. I purchased the VPS through a special offer, so I didn't think it came with support.

    Have you received your IPv6 subnet already? If you've got yours, I have added my subnet to my London location with this configuration in the /etc/networking/interfaces file:
    (Can't get formatting to work from mobile)

    allow-hotplug ens3
    iface ens3 inet dhcp

    iface ens3 inet6 static
    address 2a0e:****
    netmask 64

    Note that I don't need a gateway for IPv6. Additionally, you might need to reboot.
    Hope this could help.

    They're not going to manage your server for you but they'll answer a question like this. Did you use a /64 for the subnet mask?

    You could also try clicking the Reconfigure button at the bottom.

    @Skidmark Have you completely power cycled (shutdown & power on) your VM after you have added the new IPv6 address in the control panel? With HostHatch IPs are only added to the firewall on the host node upon VM boot. If you miss that you won't have any IPv6 connectivity from your VPS.

    I just did (as well as clicked on the Reconfigure Networking button that took a while and resturned a something went wrong error) and now it's working! Thanks for all your help!

    Don't think he ever did. After all, he had LET support crew.

  • Just wondering whether anyone has mentioned Hetzner yet

    "Linux will run happily with only 4 MB of RAM, including all of the bells and whistles such as the X Window System, Emacs, and so on." (M. Welsh & L. Kaufman, Running Linux, 2e, 1996, p. 32)

  • I'm also trying to get IPv6 running on my London storage VPS but didn't succeed yet. Ticket has been open for two months now but support was not very helpful since I've installed the VM from ISO and not from their template. Any help from the forum would be much appreciated.

    /etc/network/interfaces:

    iface ens3 inet6 static
      address 2a0e:dc0:5:25::2
      netmask 48
      gateway 2a0e:dc0:5::1
    

    ens3 is up:

    2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
        inet6 2a0e:dc0:5:25::2/48 scope global 
           valid_lft forever preferred_lft forever
        inet6 fe80::216:3cff:fe9b:a669/64 scope link
           valid_lft forever preferred_lft forever
    

    Routing looks ok:

    2a0e:dc0:5::/48 proto kernel metric 256 pref medium
    fe80::/64 proto kernel metric 256 pref medium
    default via 2a0e:dc0:5::1 metric 1024 pref medium
    

    However, I can't ping the gateway:

    # ping6 2a0e:dc0:5::1
    PING 2a0e:dc0:5::1(2a0e:dc0:5::1) 56 data bytes
    From 2a0e:dc0:5:25::2 icmp_seq=1 Destination unreachable: Address unreachable
    

    The corresponding tcpdump only show this, no responses:

    13:17:23.953004 IP6 2a0e:dc0:5:25::2 > ff02::1:ff00:1: ICMP6, neighbor solicitation, who has 2a0e:dc0:5::1, length 32
    

    When I try to ping my VM from another host, the only packets I see in tcpdump are:

    13:18:40.279383 IP6 2a0e:dc0:5::1 > ff02::1:ff00:2: ICMP6, neighbor solicitation, who has 2a0e:dc0:5:25::2, length 32
    13:18:40.279723 IP6 2a0e:dc0:5:25::2 > 2a0e:dc0:5::1: ICMP6, neighbor advertisement, tgt is 2a0e:dc0:5:25::2, length 32
    

    I also see other hosts looking for 2a0e:dc0:5::1

    13:17:31.658898 IP6 2a0e:dc0:5:14::2019:af0f > ff02::1:ff00:1: ICMP6, neighbor solicitation, who has 2a0e:dc0:5::1, length 32
    13:44:32.173509 IP6 2a0e:dc0:5:2::2 > ff02::1:ff00:1: ICMP6, neighbor solicitation, who has 2a0e:dc0:5::1, length 32
    

    Does anybody have any idea what I'm doing wrong? Is there anybody who has this running in London?

    Install OS using their template, check the network, if working, copy /etc/network/interfaces, then install from ISO...

    This isn't practical if OP has already uploaded data to it.

    What I would suggest is to ask the provider if they can supply you with a new system that you can try IPv6 on for free for a short time. If it is template installed and you can get IPv6 to work then you can try to apply the settings to your existing box.

    Your configuration seems okay. I don't think it's your fault. That's exactly the same symptom as my Chicago storage server had two months ago. Well on the bright side, @Abdullah said they will improve their support from the beginning of 2020 and that's only 10 days to go.

    @rchurch Honestly, that seems to much effort for both parties just to get IPv6 running. Their control panel provides some detail on how to configure it manually and that only mentions address, netmask, and gateway. If anything else is required that should just be added there.

    @psb777 Thanks for your feedback. I've read about IPv6 issues with their Chicago service but nobody ever mentioned London. Has this issue been resolved for your VPS after the recent maintenance?

  • FYI, my ticket has been resolved. It was an error on their side: apparently the automatic update of their firewall rules had failed and it was blocking IPv6 connection from/to my VM.

    It's working now, so all good :-)
