How do you delete the text in hamchat or can't you?

Yes, the (original) intention was to make the NTP server plug-n-play at any port by including a DNS server on the same Arduino. I had so much difficulty with that since I was learning too much in too short a period of time (NTP, DNS, IP protocols), that out of frustration, I placed the completed (and wonderfully functional) NTP server on one node and pointed all my other nodes to its address. It allowed me to move on to more pressing issues since I dairy farm and it's Spring. I can email you the Arduino sketch if you wish to play with it.

As it turned out, somewhere along the way I probably had the entire thing working... DNS & NTP but since the nodes wouldn't lock on due to too extreme a time/date difference, I assumed the worst and got more and more frustrated with my efforts. Now that I know that the NTP server works (after loosening the restraints on the ntpclient properties) I'll retry some of my earlier revisions and report back any victories.

Whew! I was able to reinstall the firmware via ssh (via port 2222) using the instructions from openwrt here: http://wiki.openwrt.org/doc/howto/generic.sysupgrade#copy_your_firmware_to_your_router

The key was to use the sysupgrade image.  The factory image causes an error.

Moral of the story: as long as you can connect to the router there is hope!

Jesse,

Try holding the reset button longer than 12 seconds to get a full reset and reboot. There's functionality tied to the reset button and it differs depending on how long you keep it pressed.

Given that error message either the file name is getting changed, either by you or the computer you're uploading from, OR the Perl script that generates the Admin page is boogered up.

Could you please post a screenshot JUST BEFORE you press the [Upload] button when you get the error message?

After that, please stop the frustration and just upload the full .trx file. :)

Check the release notes:

http://www.broadband-hamnet.org/download/firmware/ubnt/310/release-notes-3.1.0.pdf

On the sixth page (the pages aren't numbered, jeez) read "DMZ and LAN Port Distinctions". 

Granted, description of fundamental functionality is NOT something that should be buried in the release notes.  In fact, it ought to be visible on the config screen.  For example "WAN (VLAN 1)", or something similar.  But user documentation is not a strong suite of this project.

I have started a new Yahoo Group as a site to share info on Metro Phoenix mesh activities. We also have installed a few high profile nodes in the East Valley at 2500' ASL and are looking for some connections.

Give the group a visit for full information.  Let's get meshing..

Running Linksys WRT54G nodes and I have the same problem.  Getting the same error when trying to install the patch to go from 3.0.0 to 3.1.0.  I have checked and checked again to make sure I have the right file and I do.... any suggestions?

OK. I've mistakenly installed the 3.1.0 Linksys patch on my Ubiquiti nano loco M2!  Is there any way to recover?

The router appears to be running, I can ssh into it.  But when I try to get to the web interface (http://localnode:8080) I get the following message:

"The CGI process did not produce any response"

Is there anyway to recover? I've tried holding the reset button to start tftp but the router wont go into tftp mode.

Help!

It looks like I'm going to miss Ham-ex, so I'll miss your booth. Watch for our emissaries from the Hamilton Amateur Radio Club; I've asked them to visit on my behalf.

Are there any discussions going on about tunneling? Now that it's dead simple to set up, seems like a decent way to attach our many 'island' nets to the larger mesh. In Hamilton, we have a decent hub at our repeater site, but no members live close enough to connect via RF. You have a better line of sight across the bay to our site than any of us have. Ironic, eh?

I have a BBHN 3.1 tunnel server set up at my home QTH with unlimited broadband just itching for a few connections. Given that I live in an area that prevents me from connecting anywhere via RF, tunneling is an attractive feature that I'd like to explore.

I'm trying out the VTUN tunneling using Linksys 54GS's. At one end is a cable ISP with a home router, port forwarding set per the user docs for port 5525, static IP established via dyndns service. That's the server end.

At the client end, I'm using a cell phone wifi hotspot linked to the client node via a dd-wrt client bridge setup. Internet access via the client node works ok with the gateway set to on. Other nodes local to the client can access the internet via the cell phone.

On the client tunnel admin page, the link is shown as 'active', the little dot is present. On the OLSR status page, the VTUN interface is up. On the mesh status page, there are entries for remote nodes at the far end of the tunnel.

Oddly, the name of the server node doesn't appear in the client node's neighbor list. There is an entry showing the network IP for the tunnel.

So, everything looks decent, but the tunnel won't pass any traffic. When I click on the mesh status page link for a remote node. I get a timeout or connection refused error.

I've tried two different cell phones, using two different carriers, with identical results.

Is it possible the cell phone companies are blocking payload traffic, but allowing the TCP control traffic?

I haven't yet tried connecting via another landline based ISP. If anyone would like to try a test connection, please e-mail me at my callsign at gmail.com.

A group of us in the Wickenburg/Congress, AZ area have tested with both the Linksys and Ubiquiti devices. We have used IP phones and IP camera for our testing. 1. The low power of the Linksys devices make them suitable for the last (mile??) local hook-up. The Ubiquiti devices have performed out in the desert with good quality phone audio and video at 5 miles. The setting was foothills on one end and valley on the other end. It appears that you do have to pay attention to the Fresnel zone. Height on the units is your friend. 2. We have had some surprising results on the back side of the sector antennas - nanostation M2 to rocket 120 deg sector at about a mile. 3. The video and audio drop out shortly after 5 miles with the Ubiquiti Rocket  120 deg sector  to NSM2. 4. The Linksys have worked well to multiplex phone and camera behind a sector antenna - better to direct connect if you can. 5. Our testing at 8 miles did not yield good results, but then we were aiming over the top of 30+ other 2.4Ghz routers. 6. We have not had good success with amps on the Linksys. 7. I have encountered several problems between the chair and the keyboard - but I am pleased with our successes.

I want to confirm my understanding of setting the TX and RX antennas to "Diversity" on a dual-chain Ubiquiti device (such as a Rocket) connected to a dual polarity antenna (such as a Rocket Omni).  A few questions:

(I'm only looking for facts, not conjecture.  No guesses please.)

1)  Is it correct that the "Diversity" setting will use one of the chains at a time, whichever is hearing the stronger signal?

2)  In a mixed environment, where some devices are dual-chain/polarity (like a Rocket) and some devices are single chain/polarity (like a Bullet), I presume it's best to set the dual-polarity devices to always use a single chain/polarity -- whichever is the same polarity as the single chain devices.  Correct?

3)  In a point-to-point link, I presume it is NOT possible to get full-duplex comms if the TX and RX are set to separate chains.  For example, radio 1 TX=chain0/horizontal, RX=chain1/veritcal, and radio 2 TX=chain1/vertical, RX=chain0/horizontal.  Correct?

4)  Why can't the dual-chain devices use both chains at the same time with BBHN software?

Thanks much!
