# Williams Monero gruvedrift eventyr
Dette dokumentet er for å hjelpe meg, men kanskje det kan hjelpe deg også? :)
# Statistikk
Her finner du statistikk til gruvearbeiderene.

# Gruvedrifting
Her finner du litt informasjon om åssen ting er satt opp.
Jeg bruker
* [XMR-stak](https://github.com/fireice-uk/xmr-stak/releases) til 'mining'
* [2Miners](https://xmr.2miners.com/) som mitt PPLNS basseng.
Min konto adresse for innkommende XMR:

# Installasjon av gruvearbeider
Debian Buster/Ubuntu 20.04
Installer pakker som trengs:
apt install msr-tools numactl
Jeg legger til mer ting senere

* Network timeouts.
* Because of the way this client is written it doesn't need to constantly talk (keep-alive) to the server to make
* sure it is there. We detect a buggy / overloaded server by the call timeout. The default values will be ok for
* nearly all cases. If they aren't the pool has most likely overload issues. Low call timeout values are preferable -
* long timeouts mean that we waste hashes on potentially stale jobs. Connection report will tell you how long the
* server usually takes to process our calls.
*
* call_timeout - How long should we wait for a response from the server before we assume it is dead and drop the connection.
* retry_time - How long should we wait before another connection attempt.
* Both values are in seconds.
* giveup_limit - Limit how many times we try to reconnect to the pool. Zero means no limit. Note that stak miners
* don't mine while the connection is lost, so your computer's power usage goes down to idle.

/*
* LARGE PAGE SUPPORT
* Large pages need a properly set up OS. It can be difficult if you are not used to systems administration,
* but the performance results are worth the trouble - you will get around 20% boost. Slow memory mode is
* meant as a backup, you won't get stellar results there. If you are running into trouble, especially
* on Windows, please read the common issues in the README and FAQ.
*
* On Linux you will need to configure large page support and increase your memlock limit (ulimit -l).
*
* To set large page support, add the following to "/etc/sysctl.d/60-hugepages.conf":
* vm.nr_hugepages=128
* You WILL need to run "sudo sysctl --system" for these settings to take effect on your system (or reboot).
* In some cases (many threads, very large CPU, etc) you may need more than 128
* (try 256 if there are still complaints from thread inits)
*
* To increase the memlock (ulimit -l), add following lines to /etc/security/limits.d/60-memlock.conf:
* * - memlock 262144
* root - memlock 262144
* You WILL need to log out and log back in for these settings to take effect on your user (no need to reboot, just relogin in your session).
*
* Check with "/sbin/sysctl vm.nr_hugepages ; ulimit -l" to validate
*
* Memory locking means that the kernel can't swap out the page to disk - something that is unlikely to happen on a
* command line system that isn't starved of memory. I haven't observed any difference on a CLI Linux system between
* locked and unlocked memory. If that is your setup see option "no_mlck".
*
*
* use_slow_memory defines our behaviour with regards to large pages. There are three possible options here:
* always - Don't even try to use large pages. Always use slow memory.
* warn - We will try to use large pages, but fall back to slow memory if that fails.
* no_mlck - This option is only relevant on Linux, where we can use large pages without locking memory.
* It will never use slow memory, but it won't attempt to mlock
* never - If we fail to allocate large pages we will print an error and exit.

* TLS Settings
* If you need real security, make sure tls_secure_algo is enabled (otherwise MITM attack can downgrade encryption
* to trivially breakable stuff like DES and MD5), and verify the server's fingerprint through a trusted channel.

* tls_secure_algo - Use only secure algorithms. This will make us quit with an error if we can't negotiate a secure algo.
