so if  the web interface is your problem. disable it..
a 15 digit password and no standard username makes any bruteforce attack on it impossible..
if anyone hacks my units, i salute the for the hours of hashing they might steal from me..
creating a storm in a teacup.

There is more than the username/passwd combo to web interface security

Don't hook random appliances up to the interwebs without any firewalling, just common sense

From default passwords to debug backdoors accidentally left open, I've seen it all in the past

i see, so you have found a backdoor to ddwrt? it is a firewall. maybe post this to them and they can update with your hack for next update! and again, no idea where you get "without firewalling" from. ddwrt is an opensource firewall..
Setting an avalon, which already has a firewall behind a firewall, is no specific added security.. especially if it is a standard dlink or netgear.. A firewall is only as safe as it can be configured. DDWRT is a secure opensource firewall.
Hooking up a pc using cgminer all public ports could not be adviced. However, cgminer in this case is running on top of a ddwrt firewall.

I bought a Batch 1 Avalon and want to replace the power supply with a bigger one. Can anyone suggest a power supply to use that will fit inside the case?

Looking at the 850's they are longer than the 620w that's inside and I am not sure if it will fit?

Thanks


I am using the Corsair TX850M PSU to power my 3-module Avalon.  This PSU is only 160mm in length (max for Avalon is 170mm).  It is also very efficient (85% efficiency) and rated for operation at up to 50° C.  I paid $120, but looks like the price has dropped to just $102.

example lack of enough cooling pasta


5 tubes artic silver 5 - 12 gr is enough or not for 320 chips

total 60gr

if it resolv problem i do quickly for sure

ckolivas, can you take a look at my posted debug output ?

http://pastebin.com/PgfS5jzT
What's the symptom? The debugging output looks normal.

The Avalon is not hashing, it allways shows 0 MH/s.

So the cronjob restarts every 2 minutes cgminer, cause it does not submit any shares.

their s alot of problem with last Firmware.  
Excuse me?

the last page here describes alot of problems and all use the latest firmware

many grilled modules

bullshit

the last page has many mentions of the latest firmware because that is what most people are running as it is the most stable

More and more systems are getting crippled as they are coming to the end of their lifespan due to crappy Avalon assembly (for example lack of enough cooling pasta)

Don't blame the software for a hardware problem

I dont think its a firmware related problem.

You're blaming the wrong thing, but that's fine, you go on believing whatever you want...

Ck's last firmware is probably the best firmware for the Avalons. Runs for weeks on end in my 4 module batch 2 without issue.

The many grilled modules are likely a result of avalon's crappy quality control.


what is the solution ?

its not insecure.. ddwrt is one of the most secure firewalls.
is you access fully open, then its config, not related to showing ddwrt to public.
keep a safe password and your safe.

Firewalls should not run a web interface pointing to the interwebs

so if  the web interface is your problem. disable it..
a 15 digit password and no standard username makes any bruteforce attack on it impossible..
if anyone hacks my units, i salute the for the hours of hashing they might steal from me..

Indeed!  The many grilled modules are likely a result of avalon's crappy quality control.

My b3 has been very stable on 20130821 and faster than the 20130730 it shipped with.

Nice work ckolivas!!     Smiley

I do not blame anyone in particular. I just see that everyone who uses the latest firmware have problems. surely coincidence Huh?

Hello,

one of my Avalons stoped hashing today.
I restarted it, but it did not work.

Than i enabled the debug output:
http://pastebin.com/PgfS5jzT

It seems that the USB is not working properly.

Any Ideas ? I powered it down for a minute and restared it, but still the same debug output.

Firmware: http://ck.kolivas.org/apps/cgminer/avalon/20130821/
Thanks
carlo
