| Kilroy | is there a good way to just remove ip6tables, and not have everything need it | 00:51 |
|---|---|---|
| Kilroy | I use ipv4 not ipv6 | 00:52 |
| tomreyn | Kilroy: just don't use it then. it's tiny, should not matter | 02:44 |
| Kilroy | yea but it breaks other stuff | 02:44 |
| tomreyn | how? | 02:45 |
| Kilroy | docker | 02:45 |
| Kilroy | Error creating default "bridge" network: Failed to program NAT chain: COMMAND_FAILED: '/usr/sbin/ip6tables-restore -w -n' failed: ip6tables-restore v1.8.4 (legacy): goto 'PRE_docker' is not a chain | 02:45 |
| tomreyn | oh, you're saying that your docker configuration is broken | 02:46 |
| Kilroy | I just ran one command and I think I broke it more | 02:46 |
| Kilroy | trying to fix it | 02:47 |
| tomreyn | my understanding is that ip6tables-restore would only attempt to restore what was previously there. if you'll delete the state file, i think this should solve it. | 02:47 |
| tomreyn | but then, if you can have ipv6 connectivity, then you really should nowadays | 02:48 |
| genii | I'm fairly certain that ipv6 can be turned off entirely within sysctl.conf with the net.ipv6.conf.all.disable_ipv6 setting | 02:50 |

| Kilroy | what is your issue? | 14:02 |
| heller | i'm not sure whats messing up my DNS | 14:03 |
| heller | and since i'm new to netplan, im not sure if thats configured properly | 14:03 |
| heller | i also tried to disable ipv6, but it seems to still have some ipv6 lines on eth0 | 14:04 |
| heller | i've got two servers for example, other one is working correctly. How can i check what manages it's configuration? | 14:12 |
| heller | hm. seems like ping does work if i apply -4 option | 14:38 |
| heller | some tutorials say to change /etc/default/grub but i dont have that file | 14:39 |

| mason | heller: I just read over https://itsfoss.com/disable-ipv6-ubuntu-linux/ and it doesn't seem too far off-base. | 16:56 |
| mason | I made the mistake of visiting it without NoScript or AdBlock, but so it goes sometimes. | 16:57 |
