[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

[datguywhowanders]

Seems like an old friend is stopping by slush's pool again.
Not sure if it's just the pool being overloaded or an attack.

First time I saw the unhandled exception btw.

I've been seeing (hearing really as my fans die down and then wind back up again a few minutes later) a lot of problems communicating today as well.

Are we having issues or seeing another DDoS, Slush?

Random question:  Did anyone think to take dynamic IP addresses into account when putting together this whitelist?  Having your IP address change and then suddenly having your connection refused kinda sucks.  In actuality, there's better ways of mitigating against DDoS attacks than creating a whitelist.  However, some of these ways would end up adding some overhead so I can see why you did what you did.  Still, when my miners go blank because of my dynamic IP address, that's indication that some other method needs to be thought of.

You can use dyndns. Slush has also provisioned it to allow for a domain name.

Sorry, didn't see your reply.  I just looked again and it's not me - you didn't reply.   But thanks for replying now.

Ah, sorry, I know that I wrote you a reponse, but then obviously forgot to send the form .

I'm using firefox 4.0.1 on win7 64bit.  It happens every time. 

What form/url is that? Can you catch post request somehow (for example using firebug) and send me a PM? I tested all forms but don't see anything wrong. Also application logs are empty. Weird...

I go to mining.bitcoin.cz, click on "my account", click on "lost password", enter my email address, click the button, get the error.
JS console in firefox gives me:

What's the format for a domain or IP range?

For example can I enter *.pool.provider.net ?

i'm sitting on quite a bit of unconfirmed rewards from this pool atm, and it doesnt seem to update.

Nor do my confirmed rewards seem to update at this point, has been like that since yesterday evening.

Am i doing something wrong or does it just have to do with the increased difficulty on finding blocks?

Watch the blocks and confirmations on the "Statistics" page. If you see a block get fully confirmed and you have an estimated reward for it you should see the confirmed reward move up slightly. Write the number down and track it like this.

If it's not moving at all then I would say you have some issue. What are you hashing out rate wise?

i have the same problem. the blocks get confirmed in statistics but the number for 'confirmed reward' didn't change.

Not sure what you mean there. I'll give you an example of what I use.

I use zoneedit for dynamic dns. www.zoneedit.com It's free.

Set up a free account with them.

Get yourself a domain name and use that on zoneedit's site.

I have a Linux box that is my gateway/router/firewall/web server. On that computer in my /etc/rc.d/rc.local file I added the following line.

/usr/local/bin/ddns.update

Then you can paste the following into a file and give it execute permissions. I called it ddns.update and put it in /usr/local/bin.

#!/bin/sh
#
#       DDNS Automation Script - ZoneEdit.com
#       File: /bin/ddns-update

# Set ZoneEdit.com Account Details
USER=myzoneeditusername
PASS=mypasswordatzoneedit
HOST=xxx.com,ftp.xxx.com,server1.xxx.com,www.xxx.com
EMAIL=root@server1.xxx.com

# Constants - change files if needed
TMP1=/tmp/ddns_tmp1
TMP2=/tmp/ddns_tmp2

# Send update request and save results
wget -O $TMP1 --http-user=$USER --http-passwd=$PASS --no-check-certificate \
     "https://dynamic.zoneedit.com/auth/dynamic.html?host=$HOST"

echo ZoneEdit.com - DDNS Update > $TMP2
echo Time: `date '+%T - %e %B'` >> $TMP2
cat $TMP1 >> $TMP2

cat $TMP2 | mail -s "ZoneEdit.com - DDNS Update for $HOST" $EMAIL
rm -f $TMP1 $TMP2


You could probably launch it via cron as well in case your isp updates your IP even if you do not restart your modem.

ZoneEdit may have a newer script. I've been using this one for 4 years now. You could google "zoneedit script".

If you are using a wireless router you could put dd-wrt firmware on it and simply fill in a few boxes with your info and it will do the same thing.


Then instead of putting in an ip address on slush's site you put your domain name. Ex... xxx.com

There are other dynamic dns services out there as well.

I hope this was helpful.

You have to write out the 8 digits. Some of the changes can be very small and imperceptible. If you are getting a reward of .00234561 it may get confirmed and you might not notice unless you have written it out.

i have compared the numbers. my normally reward is .01, so i would mention if the counter changes. now, everything is back to normal and it wouldn't be that tragic to loose .3 btc. i just wanted to report, there's maybe a problem.

it might be moving up very minimally, but considering the pending rewards are 0.00xxxx, it's a bit hard to track, but i'll note it down & keep comparing

hash wise, i hash out about 63 Mhash (which is low, i know)

[Justsomeforumuser]

I meant the whitelist format on slush.

[jdebunt]

on an update, the blocks are being confirmed as we speak, rewards are updating, albeit slowly

awesome tbh

[slush]

on an update, the blocks are being confirmed as we speak, rewards are updating, albeit slowly

Blocks are processed once per hour, so small delay is expected.

[slush]

on the statistics page we only go back so far...is it possible for me to see the stats for 3-4 weeks somewhere?

Try ?history=1000 as argument of stats page...

First time I saw the unhandled exception btw.

I know about "too many connections" and I'm solving that, but the rest might be normal network issue on the route...

As already mentioned, you can use domain/dyndns solution, pool is resolving actual IP. Subnets/masks are not supported yet. However whitelist is not enabled by default, so don't worry that you'll lose some shares in normal run.

[slush]

What's the format for a domain or IP range?

For example can I enter *.pool.provider.net ?

No, I cannot do DNS resolve for every incoming IP (and definitely not in time of DDoS ). Please use domain/dyndns or static IP. Subnets are not yet supported.

Reward calculation works without any problem, there is just small latency between time when block is 'confirmed' on stats page and writing block reward to confirmed rewards...
