thanks guys but I've already done everything here, not in my dhcp table on the router, even did an arp lookup on the switch. I'm a network admin this isn't something new to me Smiley

bobsag3: nope only the 2 blue lights on the board, this is why I'm thinking it is dead

The combination of NIC chipset + linux driver used by some miners, is not compatible with some switches (dell), such that dhcp doesn't work. Are your switches by chance Dell? Maybe try a different switch or router? (not saying X1 has this issue; no dell switch to test it on)

Also, the rpi version of x1 had a 192.168.1.x address. Might try them too.

Who's got the best p2pool UI?

The block hash is excluded from generation signature.

Code:
    block.payloadHash = digest.digest();

    // ???

    block.generationSignature = Crypto.sign(Block.getLastBlock().generationSignature, secretPhrase);

Flaw: Blocks can be mutated after the fact, by the account which generated the block.

The block payload hash and generation signature excluded from the block signature.

Code:
			byte[] data = block.getBytes();
			byte[] data2 = new byte[data.length - 64];
			System.arraycopy(data, 0, data2, 0, data2.length);
			block.blockSignature = Crypto.sign(data2, secretPhrase);

These bytes shouldn't be excluded from the generation signature or the block signature.

The code above, surrounding code, and relevant code in verifyBlockSignature() and verifyGenerationSignature() is fatally flawed.

Yep.

7  Other / Beginners & Help / just another developer: intro post! on: December 26, 2013, 07:45:18 AM
Interested in contributing improvements - code, devops, etc - while also looking for parties interested in developing systems for blockchain management, SVP clients, and processing transactions. Beginning w/an SVP client for Electrum and a little tool which I hope everyone will find useful. If you'd like to know more, please PM, otherwise my posts here will usually be technical. (Questions are welcome in the post too! And yes, this post is a request for whitelisting.)
