ANTMINER S3+ Discussion and Support Thread

[suchmoon]

What am I doing wrong here?

Is your PC connected directly to the Ant? Are the Ethernet port lights on/blinking on the PC? Are Ant's fans on?

Sorry, I don't remember what the Ant's LEDs should be doing.

1. I've tried it directly connected and to the router. Result is so far the same.

2. The ethernet port lights are not blinking.

3. The fans are both on.

Do this with direct connection only. Try another Ethernet cable. If Ethernet lights are not on and/or the connection icon on the PC has that little red x on it, you don't have a connection with the Ant, and this is before it even comes to IP addresses etc. Could be bad cable, or bad Ant (I'm assuming your PC's Ethernet port is working).

Edit: one more thing to try would be to connect the Ant to the router just to verify if router's Ethernet port lights come on. If not then there might be something wrong with the Ant. Try resetting it.

Keep in mind that if you direct connect the ethernet cable you'll need a crossover cable or a special crossover adapter like this one for that to work properly. http://www.amazon.com/Cables-Unlimited-Cat6-Crossover-Adapter/dp/B00030BYJI/ref=sr_1_10?s=electronics&ie=UTF8&qid=1409967632&sr=1-10

That is no longer necessary unless you are dealing with old equipment that doesn't support Auto MDI-X. I'd be really surprised if S3 didn't support it.

Not true. I've been in IT for 8 years now, and I haven't had to use a crossover in probably the last 5 of those. Just plug any old ethernet patch cord, and it'll work.

Thoughts on whether or not B8 will sell out?  Just curious.

Ahh the good old days when I would carry a crimper around and just chop off the end and recrimp after I moved the wires. Thankfully technology has fixed that little headache as others have noted.

Anybody remember having to use terminators on those BNC cables?  Pain in the a$$

At current price, maybe but I don't think it will, depends on where diff is come shipping time.

Has anyone tried the new firmware?    https://bitmaintech.com/support.htm?pid=007201407180243004432lBQW28O0633

I found only one difference - default frequency for S3+ is 225M
still looking for others...

[PatMan]

I urge nobody to use this - I've downloaded it 4 times now & the MD5 checksum DOES NOT MATCH THE ONE POSTED WITH THE DOWNLOAD LINK

@Bitmain - did you post the correct MD5 number?

All of my 15 Antminer S3   (Batch 4-6) work great with this new firmware.

I'll wait until they sort out the MD5 problem. Can you tell me what version cgminer is in there? Cheers.

the same, 3.12.0

[PatMan]

So, new firmware with old security vulnerabilities and code........hmmmmmm

Why Bitmain?

[Tigggger]

What am I doing wrong here?

You have the default gateway set as 192.168.1.99 that's not right, it needs to be set to your router IP (probably 192.168.1.1 or 192.168.1.254)

Your router *might* be 192.168.1.1 so I would change that as well

So maybe
192.168.1.10
255.255.255.0
192.168.1.254 <- Router IP, whatever it is

What? Why on earth are Bitmain still using this old, outdated, inefficient & security flawed cgminer version in a new firmware release? It makes absolutely no sense whatsoever.....

@ Bitmain:  You promised the community that you would update to the latest cgminer version that fixes the security vulnerabilities and includes many improvements weeks ago - yet you are still using it in a brand new firmware release? Cgminer version 3.12 is not safe to use & is inefficient - please use the latest version as you promised us you would.

Edit:  This firmware adds support for the S3+ - does that mean that you will be shipping all S3+'s with known security issues & outdated cgminer software?

[rsclark3]

I concur with #IYFTech. Bitmain stated that they would release the firmware and update cgminer. The new firmware contains the same insecure and inefficient cgminer version. We should all demand that they install a version 4.x instead of this very early version.

Thanks 

A quote from August 17th - three weeks ago:

The cgminer software that you are deploying.......with your software has SEVERE security flaws, including the stratum redirect issue - why are you NOT implementing the latest version to eliminate these issues?

Thank you.

+1 I support this sentiment completely

Could you elaborate on what the security issues are, and what you mean by ineffecient?

I don't mean to be lazy, but if I read through the boards on these issues I'll likely find lots of conflicting information. 

Security issues... What if I'm behind a Barracuda Firewall?

Inefficiency... Meaning a more current version of Cgminer would hash faster?

Many thanks,

Strato

[PatMan]

The most dangerous security vulnerability in that version of cgminer is called the "stratum redirect" issue. It allows a third party to redirect your hashing to a different pool of their choice & claim the BTC mined with your miner. This was fixed in a later version, as well as other fixes & improvements to drivers etc - increasing performance & using less cpu/resources.

Edit: No matter what firewall you use.

Edit1: I believe it affected all miners that used the stratum protocol - not just cgminer.

[IYFTech]

Exactly. Meaning everyone using Bitmain hardware is at risk having their hashing power redirected to a different pool without their knowing, losing valuable BTC to a third, unscrupulous party/person.

Not good.

But wouldn't the attacker have to know or have some information about your miner? Such as IP, etc?
