Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

I've been working with rav3n_pl to find out why my local Stratum mining proxy cannot connect to p2pool anymore, after upgrading to p2pool v10.
Finally we reported an issue on Stratum mining proxy: https://github.com/slush0/stratum-mining-proxy/issues/6
That's what slush respond:
Quote
slush0 commented a day ago

It is server side problem; server should send mining.notify message directly after mining.subscribe and not wait for mining.authorize.

Please ask server operator to fix it on his side.
Help needed Smiley

I was about to reply with the same problem that saw the updated version. I just updated hope that it solved the issue, I had lots of orphaned shares on v10 so far...

btw is there any way to prevent the statictic's reset when restarting p2pool?

Nope. Number of shares is counted from 0.
But rest of stats is in the graphs, they are not lost.

Source tarball: https://github.com/forrestv/p2pool/tarball/11.0

Changes:

I not understand, why ppl hacking code so bad...
Code:
2013-01-04 11:22:16.984000 Outgoing connection to peer 82.224.192.145:9323 established. p2pool version: 1100 '9.4-45-g0981bdf'
2013-01-04 11:22:32.818000 Outgoing connection to peer 94.224.37.118:51333 established. p2pool version: 1000 '10.0-dirty'
2013-01-04 11:22:33.972000 Outgoing connection to peer 91.235.254.37:9323 established. p2pool version: 1100 '11.0-2-g0981bdf'
2013-01-04 11:23:41.505000 Outgoing connection to peer 46.105.103.55:9323 established. p2pool version: 1100 '9.4-45-g0981bdf'
2013-01-04 15:07:00.230000 Outgoing connection to peer 81.83.16.111:51333 established. p2pool version: 1000 '10.0-dirty'
Find 2 bad hacks.
This is on TRC nodes, will check other ones later.
It is so easy to keep things updated, why messing in code this way? It is always bad way...

Edit:
On BTC I found:
Code:
connection to peer 71.227.175.139:9333 established. p2pool version: 1000 '3.1-236-g2dffea0'
connection to peer 84.208.55.32:9333 established. p2pool version: 1100 '9.0-140-g5c1786a'
connection to peer 71.227.175.139:58337 established. p2pool version: 1100 '3.1-244-g0981bdf'
And few funny "version: 1100 'madness'" and lots of "unknowns".

On LTC side only some unknowns.
