Hmm... Its been a while since I looked at the firmware versions. I think there might have been a custom one someone compiled that had some fixes in it - this might have been one of them.

I've tried two different image files from what I've found on the forum but none of them worked.

Anyone willing to take out their sd card and make a image of it then upload for others?

Thank in advance!

Downloading. Uncompressing. Burning to micro with image file software.

Antminer will boot software and connect to network but doesn't hash.

This is an image I'm using in my S2's right now, so I know it's good:

Hope it helps you, let me know  

Use win32diskimager to put it on the SD. Use a quality class 10 SD.

Dogie,

Have you done any overclocking or volt modifications to an s2 yet? I was thinking of looking into an s1 board and comparing it to that of the s2 to see what can be modified to push our systems to the max. Any thoughts?

I'm also getting ssh attacks. pool are changing information
How do I change the ssh port

I have antminer s2.I run this antminer at a datacenter.Although i have changed my web and shh datas,somebody is changing my pool datas.What can i do ??

Get a better firewall if people are getting in to your machines.

I'm not sure, but this could be a stratum redirect attack - it's due to Bitmain using an older security vulnerable cgminer version. Bitmain promised to update cgminer over 7 weeks ago, but have yet to do so. You should email this screen to them asking for an explanation
