Install Miner with EthOs with your Mac Osx


Install an usb stick with EthOs (1.2.9) on your Mac OS X

Open a Terminal (in /Applications/Utilities/)

Download (and buy) the EthOs from:
unpack the file with : xz -d ethos-1.2.9.img.xz or if you don’t have the xz decompressor use
gunzip ethos-1.2.9.img.xz
Nou you have a file called: ethos-1.2.9.img

Insert your flash media USB stick
Run: diskutil list and determine the device node assigned to your flash media (e.g. /dev/disk2)

Run diskutil unmountDisk /dev/disk2 (replace 2 with the disk)

Execute: sudo dd if=/path/to/ethos-1.2.9.img of=/dev/rdisk2 bs=1m (replace /path/to/ethos-1.2.9.img with the path where If you see the error dd: Invalid number `1m’, you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
This take a while… take coffee and a lunch!
Run diskutil eject /dev/disk2 and remove your flash media when the command completes

Now you can boot de server with the USB stick and install the software on the miner…

restore telnet in Mac OSX High Sierra

You can use “nc” to check for (open) ports
This program NetCat is included in Mac OSX High Sierra
nc 25
if this is not enough you can install telnet from HomeBrew

# install HomeBrew as a regular user (not root)
/usr/bin/ruby -e “$(curl -fsSL”

# get telnet
brew tap theeternalsw0rd/telnet

# install telnet
brew install telnet

telnet 25

Install FreeRadius on CentOs 5 and 6, Using Mysql, with NT-Hash passwd’s for Wifi Routers

install freeRadius
# source

CentOS 5:
 yum install freeradius2 freeradius2-mysql freeradius2-utils mysql-server -y
CentOS 6:
 yum install freeradius freeradius-mysql freeradius-utils mysql-server -y

They should install without any problems. To setup MySQL, start the service by running below:

 service mysqld start

Now run the following to set your password and security settings:

mysql -uroot -p
 GRANT ALL PRIVILEGES ON radius.* TO [email protected] IDENTIFIED BY "radpass";
 flush privileges;
mysql> use radius;
 SOURCE /etc/raddb/sql/mysql/schema.sql
Now open up CentOS: /etc/raddb/sql.conf and enter your mysql database details you just created, Example:  # Connection info: server = "localhost" #port = 3306 login = "radius" password = "radpass"

# Database table configuration for everything except Oracle radius_db = “radius”

In /etc/raddb/radiusd.conf ensure that the line saying:
$INCLUDE sql.conf is uncommented.
Edit /etc/raddb/sites-available/default and uncomment the line containing
 ‘sql’ in the authorize{} section and ‘sql’ in the accounting {} section, also uncomment ‘sql’ under session {}.
Additionally, edit /etc/raddb/sites-available/inner-tunnel and uncomment the line containing
 ‘sql’ under “authorize {}” and under session {}.
Open up /etc/raddb/clients.conf set your secret to something a bit more random, example:
secret = testing123 To something like: secret = 3c23498n349c3yt290y93b4t3
service radiusd restart
 service radiusd stop
To add clients (External VPN Servers) you would edit CentOS: /etc/raddb/clients.conf Ubuntu: /etc/freeradius/clients.conf and directly under this line:
 # coa_server = coa
 } Add a block such as this:
client VPN_SERVER_IP { secret = YOUR SECRET HERE shortname = yourVPN nastype = other }

To allow external servers and software to authenticate off your FreeRADIUS, this has to be done every time you setup an external server to use this FreeRADIUS database.

Everytime you add a client or change a value in the config files you need to restart radius like this:


service radiusd restart

Add a test user to the radius database, first you need to login to your mysql radius database:
mysql -uroot -pyourrootpass

Switch to the radius database:

use radius;

Once there execute the below commands:

# overview of the user table

desc radcheck -> ; +———–+————–+——+—–+——————–+—————-+ | Field | Type | Null | Key | Default | Extra | +———–+————–+——+—–+——————–+—————-+ | id | int(11) | NO | PRI | NULL | auto_increment | | username | varchar(64) | NO | MUL | | | | attribute | varchar(64) | YES | | Cleartext-Password | | | op | char(2) | YES | | := | | | value | varchar(253) | NO | | | | +———–+————–+——+—–+——————–+—————-+ 5 rows in set (0.04 sec)

if you want “plain passwd’s you can use this.

mysql> INSERT INTO `radcheck` (`id`, `username`, `attribute`, `op`, `value`) VALUES (1,'test','Cleartext-Password',':=','test');
radtest test test 0 mysecret

If you see “rad_recv: Access-Accept” then your installation is working fine.

If you want to use “NT-Hash passwd” it’s more save then plain-text. (not 100% save)

INSERT INTO `radcheck` (`id`, `username`, `attribute`, `op`, `value`) VALUES (1,’test’,’NT-Password’,’:=’,’0CB6948805F797BF2A82807973B89537′);

With the following command you can add users into the mysql table (perl and libraries required)
you need to :

yum install perl-Crypt-SmbHash.noarch perl-Class-DBI-mysql.noarch libdbi-dbd-mysql.x86_64

 ( raduseradd.cgi download here)

use DBI;
use Crypt::SmbHash;
# script by Marcel Kraan 
$dserver        =       "localhost";
$ddatabase      =       "radius";
$duser          =       "radius";
$dpassword      =       "radpass";
undef $usercheck;
undef $doublecheck;

$dbh = DBI->connect("DBI:mysql:database=$ddatabase;host=$dserver", "$duser", "$dpassword")||die "login/dbase/passwd/host error";

$username = $ARGV[0];
$password = $ARGV[1];
if ( !$password ) {
        print "Not enough arguments\n";
        print "Usage: $0 username password\n";
        exit 1;
ntlmgen $password, $lm, $nt;

$query = "SELECT username from radcheck where username = '$username'";
$sth = $dbh->prepare("$query");
die $dbh->errstr unless $sth && $sth->execute;
while(@row = $sth->fetchrow) {
        $usercheck          =       $row[0];

if ($usercheck){
        print "user: $username already exist\n";
        $query = "SELECT username from radcheck where username = '$username'";
        $sth = $dbh->prepare("$query");
        die $dbh->errstr unless $sth && $sth->execute;
        while(@row = $sth->fetchrow) {
                $doublecheck          =       $row[0];
        if ($doublecheck){
                print "user $username succesfully added to the database\n";

sub useradd {
        $query = "INSERT INTO radcheck (username,attribute,value) VALUES ('$username','NT-Password','$nt')";
        $sth = $dbh->prepare("$query");
        die $dbh->errstr unless $sth && $sth->execute;

If you have any problems with FreeRADIUS you can run FreeRADIUS in debug mode to help pinpoint any issues, to do that just do the following:

 service radiusd stop
 radiusd -X
