 |
|
I noticed that I cannot reach some websites, such as "kernelnewbies.org". And it's most likely a DNS problem.
"/etc/resolv.conf" looks like this:
| Code: | # Generated by dhcpcd for interface ath0
nameserver 192.168.1.1
|
And the problem can be shown by this command:
| Code: | $ host kernelnewbies.org
kernelnewbies.org has address 32.2.74.92
;; Warning: Message parser reports malformed message packet.
|
(I then have to kill the process because it doesn't exit)
After I replace "/etc/resolv.conf" with my own version that has the DNS servers from my ISP in it, the output is different:
| Code: | $ host kernelnewbies.org
kernelnewbies.org has address 74.92.59.67
kernelnewbies.org has IPv6 address 2002:4a5c:3b41:1:216:3eff:fe57:7f4
kernelnewbies.org mail is handled by 0 forlond.surriel.com.
kernelnewbies.org mail is handled by 5 shelob.surriel.com.
kernelnewbies.org mail is handled by 10 forlond.surriel.com.
|
So is this caused by a malfunction in our ADSL router? Can I do anything about it?
Replacing the file "/etc/resolv.conf" is no real solution because dhcpcd overwrites it regularly.
The device is a D-Link DSL-G624T, with firmware "V3.10B01T02.EU-A.20070613".
Would you guys recommend that I try some other (custom) firmware?

Trying a new firmware could be worth a try, but its a work-in-progress with the most popular OSS firmware for this router.

You don't have to allow the overwrite. See your net.example file. Then try using the opendns.com servers instead of your ISP's.

| For the ath0 script to stop overwriting your DNS records at startup, u can add to /etc/conf.d/net. |

On the other hand, you might find that the problem is not you and that kernelnewbies.org is in the Internet boonies (it is *25 links* away from me by traceroute,) and is not answering at present

It's not just that website, I have it with others as well, but often not the top level domains. Like I cannot download updates for
my Firefox add-ons with the setting generated by dhcpcd. But I don't have problems with other parts of the Mozilla website.
Now I could adjust the DNS settings on my computer as you people recommended, but that is still not a real solution. It does
not help my family members here who have the Windows thing on their laptops, though I don't know if they have
experienced the problem yet. But I'm not the only Firefox user here, so... Maybe I should ask them.
I have upgraded the router's firmware a few times already, but it's still the "official" firmware and that did not solve the
problem. OpenWrt is not an option yet; their webpage says that wireless will not work on this device  |

Your router is acting as a DNS relay.
Check your configuration options, and see if you can turn this "feature" off. |

Oh, I didn't know it was something you could turn off. I thought it was somehow implied by the use of DHCP.
But I looked at the DNS settings and there was a "disable DNS relay" option. Problem solved now, thanks. |
