2  Economy / Digital goods / Re: [UK] Papa Johns 20£ Vouchers Shop [BTC] $5.00 each on: April 03, 2015, 09:42:44 PM
Are these codes just added to an account and then they can just sit there?

Do they expire?

Thanks for the replies, I'm still only upto 48 connections (max set at 200)

Code:
root@btcnode:~# bitcoind getinfo
{
    "version" : 90100,
    "protocolversion" : 70002,
    "walletversion" : 60000,
    "balance" : 0.00000000,

}

Upload speed is increasing over time, not really sure why its so slow compared to other nodes, it has 120Mb/s upstream bandwidth and is in Dallas Texas

For anyone who is interested my upload amounts have massively increased, I assume the IP addresses gains a reputation as a good node and the protocol serves it more connections over time.

These are the current stats for anyone interested:

Yep, netstat shows all the connections

upto 26 connections now:

Code:
root@btcnode:/# bitcoind getinfo
{
    "version" : 90100,
    "protocolversion" : 70002,
    "walletversion" : 60000,

    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "errors" : ""
}


The amount of bandwidth it is using is increasing over time, maybe it takes the network some time to trust a new node and give its IP out?

There is no firewall infront of the server, only iptables.

No router or NAT device just "pure" internet?

I have not purchased a router but ofc there is a router somewhere between me and the internet, do you think the hosting provider might throttle the traffic or something?

There is nothing to NAT that I have purchased, again I'm sure there is some-ware between my VM and the internet. It is uploading constantly at roughly 20 kbit/s but that might be my SSH sessions, there is nothing else on this server apart from bitcoind
7  Bitcoin / Bitcoin Technical Support / New Server Node not uploading (max 23 connections) on: May 10, 2014, 01:15:11 PM
Hi guys,

I am training into Linux and decided to make a full node on Ubuntu (13.1) as a learning project and to help the cause.

I started by following this guide: http://www.reddit.com/r/Bitcoin/comments/1se3zd/how_to_create_a_full_bitcoin_node_in_a_5_ubuntu/
(if you dont want to click the link its basically a scrypt that installs bitcoind and its dependencies and then configures iptables to open port 8333)

I let it download the whole blockchain but now it only has 21 connections (see below) and does not appear to be uploading.

Code:
root@btcnode:/# bitcoind getinfo
{
    "version" : 90100,
    "protocolversion" : 70002,
    "walletversion" : 60000,
    "balance" : 0.00000000,
    "blocks" : 300052,
    "timeoffset" : -1,
    "connections" : 21,
    "proxy" : "",
    "difficulty" : 8000872135.96816349,
    "testnet" : false,
    "keypoololdest" : 1399644917,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "errors" : ""
}

I read that alot of these problems are solved by opening port:8333 but I know its open

Code:
root@btcnode:/# iptables -L

*snip*

Chain ufw-user-input (1 references)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:8333

I changed bitcoin.conf to allow upto 200 connections which didn't help.

I have installed vnstat to check my bandwith and its using almost none. The server is a VPS with 240Mb/s bandwith (upload is capped at 120Mb/s) so it should be uploading far more than 9Mb per hour.

Code:
root@btcnode:/# vnstat -h
 eth0                                                                     13:04

Anyone got any ideas of what to try next?

8  Alternate cryptocurrencies / Mining (Altcoins) / Anyone got 5+ R9 series cards working on 1 mobo? on: January 21, 2014, 03:36:45 PM
Hi guys,

As the subject says I have bought 6 R9 290's and a mobo with enough PCI-E slots for them.

I hear that drivers 13.x + are needed for the R9 290/x but these dont allow more than 4 cards. Someone here: http://www.gobitgo.com/articles/1002...ne-with-6-GPU/ claims to have done it by installing seperate drivers on the 5th card (but not on R9 290/x)

The 5th card is showing up in windows but wont run in cgMiner (in windows it says it has no driver)

Anyone tried this? I have 4 cards running and todays prices thats about £15 per card so I am reluctant to power it off and start messing trying to get the 5th working.

I know its possible to get 5+ cards mining on 1 mobo but I find no reference to getting this working on the R9 series, can anyone shed any light on this?

I have yet to see anyone running 5 or more R9 series cards on 1 mobo

Regards,
Danny

is there a power supply that can handle 5+ R9 ?

Probably an industrial one but I am using 3 separate ones 1000/850/850  (I have used a paper clip on green to black so they fire up with power)
