Bug #405
DNS error after popping hda out of and into network
0%
Description
I had to take my hda somewhere else, so I disconnected it from the network and let the router resume handling IP requests (turned DHCP on). Everything was just fine. When I hooked the hda back, though, it stopped resolving internet addresses. I can access the dashboard and the router from the hda itself, and the hda is also reachable by other machines in the network (dashboard-, remote desktop- and remote files-wise). The hda can ping 68.180.206.184, but yahoo.com is referred to as an unknown host, so I'm assuming that something goes wrong with the DNS whenever the hda is disconnected from the original network and/or the router's DHCP is turned on again.
I've tried turning the PC on with router's DHCP on, then tried turning it on with router's DHCP off and had no success either way. In both cases, the hda gets the static IP I've set as default during Amahi's installation and everything remains the same way I described above.
Also, when the router's DHCP is turned off, the HDA seems to serve an IP address to the other PCs on the network correctly. It seems to be working just OK, except it can't resolve internet addresses.
The HDA connects itself to the network by means of cable (and eth0 device) to a Linsys WAG200G router.

can you
ping 208.67.222.222
ping 208.67.220.220these are the default DNS providers (OpenDNS).
Did the network change?
If so, use
hda-change-gw IP_OF_THE_ROUTERalso, can you tell us what step you get stuck at in the network troublshooter:

Yes, I can ping both.
1. ping hda (this ensures the dns server is working) - OK
2. ping router (this ensures your HDA can see the router) - OK
3. ping 68.180.206.184 (this ensures you can see the rest of the world) - OK
4. ping yahoo.com (this ensures your dns server can see the world) - FAIL (Unknown host)
5. in the HDA itself (if you can), access http://hda - OKBy the way, the hda-change-gw script, as well as the hda-change-dns, aren't working due to misused quotes (should be double, used single). You pointed it out to me yourself, but it seems like they haven't been updated yet. Just a reminder. :)
My network didn't change, but I tried using the script anyway and got:
DBD::mysql::st execute failed: Table '$m_database.settings' doesn't exist at /usr/bin/hda-change-gw line 81.Couldn't execute statement: Table '$m_database.settings' doesn't exist at /usr/bin/hda-change-gw line 81.

ok, so DNS is not working.
btw, the fixes are coming in Amahi 5.1 here is the latest release with them:
http://alpha.amahi.org/tmp/hdactl-3.0-5.i386.rpm(that is the 32b - change appropriately for 64b)
do this before and after installing the above rpm (with rpm -Uvh ...):
service named statusand paste the putput here ...

Did it. Brought up the terminal, switched to root user and used the rpm -Uvh <package's path> command in between two service named status executions. The outputs were as follows:

*means "is running" in portuguese
As of right now, the HDA is still unable to resolve internet addresses. I haven't rebooted it yet and the router's DHCP is off.

ok, looks good.
next you can try:
hda-change-dns IP1 IP2where IP1 and IP2 are your providers dns , in case they are blocking OpenDNS.
you can try google's dns with:
hda-change-dns 8.8.8.8 8.8.4.4to get back to opendns:
hda-change-dns 208.67.222.222 208.67.220.220#8 Updated by phillipe almost 11 years ago
Still, no success. But I think it could be my fault. hda-change-dns was not working, so I tweaked it myself (changed single quotes to double quotes in two of its lines).
#9 Updated by cpg almost 11 years ago
wait!
when did you have to change hda-change-dns?!?!
it should be fixed by now in the hdactl you installed!!
#10 Updated by phillipe almost 11 years ago
Oh, I actually tweaked it before updating. So now it should be the official one once again.
