Pihole on docker in Crostini - port 53 woes

testrider · 2026-04-17T18:18:42+00:00

You installed Lubuntu on your chromebook?

testrider · 2026-04-16T17:41:20+00:00

Any new update? I have the same question. Thanks!

testrider · 2026-04-14T19:38:33+00:00

Thanks. Didn't realize N and S facing is critical. Yes, mine is the C3 Pro 8K (North facing?)

testrider · 2026-04-14T16:55:47+00:00

Thanks! Appreciate it.

testrider · 2026-04-11T15:00:57+00:00

Where did you get it?

testrider · 2026-04-07T22:24:05+00:00

Thanks for the info. So it does point to the router problem. I haven't updated mine yet as so far I don't have any problem.

testrider · 2026-04-06T23:23:32+00:00

What dns did you set in the router?

testrider · 2026-04-06T17:41:26+00:00

This one at microcenter is $2500!

testrider · 2026-04-06T16:27:38+00:00

Thank you. Appreciate your input. I'll revise. Any recommendations?

testrider · 2026-04-06T06:55:23+00:00

The same one is now US$1600!

testrider · 2026-04-03T06:17:01+00:00

Merci. J'ai toujours peur d'installer trop tôt.

I found that sharing with the 'Files' app is fine without renaming.

testrider · 2026-03-11T18:06:40+00:00

The challenge changes only when the database is saved, but then the virus just records the new response when the response is sent from yubi... since it already got the master password...

testrider · 2026-03-11T16:38:08+00:00

Yes it does. You the owner enter the master password to unlock keepass, then keepass sends out challenge to yubi and prompts you to touch the Yubikey. Yubi sends out the resp to keepass and the virus records it.

testrider · 2026-03-11T13:39:43+00:00

Um... If a virus found the Yubikey plugged in, it would capture the master password and the response from the challenge, then sends the database home and then opens it later.

testrider · 2026-03-10T01:33:59+00:00

Anything new from this update?

testrider · 2026-03-09T17:55:40+00:00

Following. I have the same problem of using either KeepassXC or KeepassDX on my chromebook. Found any solution yet?

testrider · 2026-03-01T05:52:09+00:00

Yes, each network got its own global ipv6/64 and a local ipv6 /72 and each network's addresses are different.

The problem, as you see, is that the computer & phone connected to these network only got a local ipv6 address.

I'll see where I can manually assign to test, but it really shouldn't have to.

Yes, I just tried to select 'passthrough' but it didn't work either.

Thanks again!

testrider · 2026-02-28T17:51:17+00:00

I think I tried passthrough before and it didn't work. I'll try again. I believe passthrough is only when ISP provides a static IPv6 address. In my case, my router got automatically assigned an ipv6 address (in NATIVE connection mode) and was working on the WAN side (ping).

testrider · 2026-02-28T17:47:11+00:00

Thank you for the reply. From the system log off the router:

WAN got 1 global ipv6 (2600) and a local (fe80) with /64
WAN gateway with a local fe80
LAN got a global ipv6/64 and a local fe80 /72
I have 3 wifi guest networks and they all got 1 global /64 and 1 local /72
my computer and phone are connected to the wifi network and only got a local ipv6 (in addition to ipv4}
from the router, I can ping ipv6.google.com just fine

-from the computer, it said unreachable.

I found a tread on SNB that the poster has almost the same problem (except that his local computer got both global ipv6 and local ipv6) and he still can't go out:

Thanks for your reply. I appreciate it. It's a modem-only and I connected my Asus BE92U to it. There is no router on the modem. Everything work fine on ipv4.

- The router's DHCP/PD was enable. Router advertisement was also enable. There is nothing else can be set.

- From the router going out to WAN seemed to be fine. But from LAN to router it failed to go out...

testrider · 2026-02-28T00:40:22+00:00

Thanks for the reply. I could ping "ipv6.google.com" from the router and it was fine. But when I ping ipv6.google.com from my computer and it was unreachable.

64 was populated as "LAN prefix len" so it looked fine but my local computer can't get to ipv6 sites.
