Rule #0: do not turn off DHCP in your router until your HDA has full network connectivity

Your HDA should be capable of browsing all the major sites and http://www.amahi.org before doing anything else.

If you do not have connectivity, you may want to check that the settings that you programmed in amahi.org for your network and router match that of your actual network and the router in it. Amahi assumes a regular, typical home network and the settings there should be done to match what you have. The most common error is that the gateway is not set up properly. We have a page on how to Find Your Gateway IP.

Please note that only the first NIC/ethernet card (eth0) is supported out of the box. If you have two, please make sure you use eth0 for the LAN where your Amahi HDA resides. There is an unsupported way to support amahi on the eth1 device.

Tell us what step you get stuck at:

Step 1

From your hda itself (via ssh or at the desktop in a terminal), can you:

  1. ping hda (this ensures the dns server is working)
  2. ping router (this ensures your HDA can see the router)
  3. ping 68.180.206.184 (this ensures you can see the rest of the world)
  4. ping yahoo.com (this ensures your dns server can see the world)
  5. in the HDA itself (if you can), access http://hda

If the above does not work, try and fix it by double checking the settings.

After the above works, you should be able to access

           http://hda

from the HDA machine's desktop!

If the above works, then and only then you may turn off the DHCP server in your router. IMPORTANT: after turning off the DHCP server, you must repair (or reboot) your client's ethernet connection(s) for them to get a new DHCP lease from your Amahi HDA.

Step 2

Then move to one or more of the clients (after their network has restarted:

  1. ping hda (this ensures the client can see the DNS server in your HDA)
  2. ping router (this ensures the client can see your network gateway)
  3. ping yahoo.com (this ensures the client can see the world)


If you want to stop by the IRC channel for help, it would speed things up to report where you are "stuck" in that list, like step 1.3, or 2.2. You should also say:

  • What client operating system are your other machines in the network using
  • At what point did you turn off your router DHCP (if you did)
  • At what point, relative to the above, did you restart (or release and renew the DHCP lease on the) clients


When all else fails

In some cases, it could be the client OS causing issues.

One known issue is the Vista_Networking_Issue
