Is there a way to configure a failover gateway in this build of openWRT?
Yes via shell script as add on. You can do whatever you want:)There is no buildin recipe to solve every problem but it is open source and you can take advantage of it and find a solution
Is there a way to configure a failover gateway in this build of openWRT?
You better use something like zeroshell as your gateway and configure multiple upstreams on a fail over setup.It's the way my home network works (well, a bit harder than this, i load balance my upstream via some magic called VPN bounding, a layer 3 stuff if i recall correctly).
Is there a way to configure a failover gateway in this build of openWRT?
but anyway, "no_matching_work" in stats api should be 0, or you may want to check the same issue.

simply, the current communication protocol / the controller? is not capable of doing error correction.
flip a bit may really cause big problem.
Super! Can you be more specific about how big problem can be?
I guess that controller has own Firmware/Software and it can be upgraded some time in the feature is that correct?

1: run into a dead loop, or returned unknown bad response (since the command may be a bit flipped one)
2: yes, but I guess it wont be a easy thing... I dont think they will release it.
but anyway, "no_matching_work" in stats api should be 0, or you may want to check the same issue.

finally the problem reason is found.
in the first machine I got, the included USB A-to-B cable is < 35cm in length (including the connectors),
during shipping the connector is dropped and I opened the case, reconnected back (so you see that I wrote that trouble).
but it didn't get fastened as the cable is short.
in the recent batch of machines, the cable is much more longer,
there is also tape to make sure the connectors never get disconnected.
so yours should be safe from this issue.

My 8M image with chip is waitng for the unit - with latest Avalon cgminer branch. Just for the record does soft restart of cgminer solves the potential issues or Power off/on is required?
I think it is a strange single? problem worth fixing, but you may never experience if you're lucky ... I mean, you should do enough monitoring, prepare for the worst. most of times power cycle is not required. if the machine needs power cycle, the light on the back of the fan will become red.My 8M image with chip is waitng for the unit - with latest Avalon cgminer branch.

Anyway I do have snmp power relay switch so i can plug off/on power when i need to automatically:)
Thank you very much for your response techwtf:)

I would like to see that snmp power switch!

There is a cron job monitor the cgminer: (compare the Accepted every 5mins, if there is no Accepted in 5mins. restart the cgminer)
https://github.com/BitSyncom/cgminer-openwrt-packages/blob/master/cgminer/files/cgminer-monitor
Can you paste the cgminer log. remove the '-q'. add '-D --verbose > /tmp/cgminer.log' under /etc/init.d/cgminer. and the 'dmsg' output.
You may want update to latest 703n image:

general i am interested to know the following:
1. Is there automated way (via script locally) to find out for sure that avalon is not hashing
2. Only power off/on solves the problem or soft reboot from the script will do the job?

Yes there are a LOT of statistics available via the API.
It's simply a case of finding what stats show the problem they are having with the hardware and using that.
(Yes from what was said before 'MHS 5s' did not go down to 0 when the problem occurred)

That number represents the last time 'valid' work was returned by the device.
Thus e.g. with an Avalon, it should NEVER reach 60s in the past (current time = STATUS/When) so you will know quickly if something has gone wrong.
It's using device difficulty (not share difficulty) i.e. it's before the share is validated as being above required difficulty, but after it is validated as not being a hardware error.

Is there a free unpopulated usb port on the internal usb hub?
I wanna install 3G as backup so i am wondering if i shall prepare additional usb hub or built-in one will be just fine?

PS: How about instability issues are they fixed with latest images?

1: yes, 4 total, 3 remaining.
2: you should use another router as upstream.
3: running & capturing debug info, if the problem appear again, related info will be submitted to xiangfu for more investigation. I do hope I can remove the monitoring script above.
Thanks!
I will use same router:)
I will install 3g USb outside the box
3g ppp interface will be up all the time and when internet dies a script will change default route only
There are no hanging issues currently right?
the hanging issue is now under investigating, even other owner have reported fine for 7days+.
