Using SSH without using or needing a password

By SteveK | Published: September 23, 2010

Linux SSH keygen -t DSA command executionI’ve tried many methods now of using SSH keys to login without a password.  Needless to say, I had to mix a couple methods to make this work.  This isn’t that hard.

Step 1) You’re on a linux machine (or putty’d into a linux box) trying to SSH into a remote host without having to use a password.   In my case i need to run automated commands to upload files to a remote host.  You need to create a SSH key for both machine.  Do this by running the following command:

ssh-keygen -t rsa

The default file should already be set, press enter.

The passphrase will remain empty (since you don’t want to type it every time you log in) Press Enter again.

Then press Enter for a third time to confirm the empty passphrase.

It should look something like the picture above.

Step 2) Upload the SSH Public Key to the remote server.  Use the following command:

scp ~/.ssh/id_rsa.pub username@whateveryourdomain.com:.ssh/authorized_keys

This will upload the file to your remote and will place the pub key file in .ssh/authorized_keys.

upload ssh key to remote host

Now type “logout” to get out of your remote host’s SSH.  Then log back in via:

SSH user@remotehost.com

It shouldn’t ask for a password anymore.  If any of this information doesn’t apply to you, or you have any questions please feel free to ask.  Thanks for reading.

Thanks to the 2 sources that I used to come up with my own, thank you:

WordPress custom menu disappear on home page when using custom post types and/or taxonomies.

By SteveK | Published: August 18, 2010
Wordpress custom menu disappears on home page.

As you’re developing a theme, you try one of WordPress’s newer options: Custom Post Types.  Searching the internet you stumble upon Justin Tadlock’s blog.  You try his way of showing custom post types on your home page of your wordpress blog.  Then boom. You’re custom menu is not showing on your homepage.  Now what do you do.

I spent about a week going back and forth with my custom taxonomies, and WordPress 3.0′s new custom menu editor trying to figure out why the hell my home page isn’t showing my custom menu.  It shows all on my other pages.

Out of all the code, from all over the internet, that I used.  I had put the following code in my functions.php hoping to show my custom post types.

add_filter( 'pre_get_posts', 'my_get_posts' );

function my_get_posts( $query )
{
    if ( is_home() )
    {
        $query->set( 'post_type', array( 'any' ) );
        //$query->set( 'post_type', array( 'post', 'products', 'downloads' ) );
        return $query;
    }
}

add_filter( 'pre_get_posts', 'my_get_posts' );

function my_get_posts( $query )
{
    if ( is_home() )
    {
        $query->set( 'post_type', array( 'products' ) );
	  //$query->set( 'post_type', array('post', '{CUSTOM-POST-TYPE-NAME}') );
        return $query;
    }
}

This code works, unless you’re using a custom menu you’ve made in the back end of wordpress.  This will for whatever reason (to which I have not investigated) make your custom menu’s disappear from your home page faster than a rabbit can crap.  So I’ve spent a whole week investigating my custom taxonomies, and wordpress’s custom menu editor, when the only thing I messed up was using Justin Tadlock’s code.

Here is what you do instead of putting that jargon of a excuse for code into your functions.php:

Pick any of your template files that show your posts or pages: pages, loop, home, index, or whatever single-{taxonomy name}.php you want to edit and add your custom post types to and add the following code above the loop:

query_posts( 'post_type=products&posts_per_page=20');

or whatever you needs may be:

query_posts( 'post_type={custom_post_types_name}');

Happy coding, and careful who’s blog you read ;) Thanks JustinTadlock I was stuck on that crap for a week.

Intelligent Security? Or a Demon Service? Here’s an article i strongly agree with…

How do I unlock my LG LW 310 Helix Phone when I never set a lock code?

By SteveK | Published: June 9, 2010

A question that pondered me for about 10 minutes. I search google and all I come across is Q & A websites with this question, and NO ANSWERS. Thanks to my co-worker for his brilliance in user electronics. He suggested trying the last 4 digits of my phone #. THAT WORKED!

SOLUTION: Last 4 Digits of your Cell Phone #

A great and FREE alternative to CPANEL or PLESK (WEBMIN in VIRTUALMIN)

By SteveK | Published: June 3, 2010

step 1: cut a hole in the box

Anyways i got all this from: http://www.howtoforge.com/virtual-hosting-with-virtualmin-on-centos5.1-p2

Love this, virtualmin / webmin kick the shit out of cpanel or plesk.. For full control of your web server use webmin instead of paying for cpanel or plesk. Webmin and virtualmin are both free and opensource. Feel free to try this out on your linux webservers.

To enhance security and free system resources on the system we need to disable any services that are not required. You can run this script to do this for you.

* acpid
* anacron
* apmd
* autofs
* bluetooth
* cups
* firstboot
* gpm
* haldaemon
* messagebus
* mdmonitor
* hidd
* ip6tables
* kudzu
* lvm2-monitor
* netfs
* nfslock
* pcscd
* portmap
* rpcgssd
* rpcidmapd
* sendmail
* smartd
* yum-updatesd

Basics

We need to fix a few issues to prepare the system for configuration.

* Install updates

yum upgrade

* Switch the mta to postfix

alternatives –config mta

There are 2 programs which provide ‘mta’.
Selection Command
———————————————–
1 /usr/sbin/sendmail.postfix
*+ 2 /usr/sbin/sendmail.sendmail
Enter to keep the current selection[+], or type selection number: 1

* Install caching-nameserver config:

yum install caching-nameserver

* Install Build tools:

yum install gcc cpp gcc-c++ automake automake14 automake15 automake16 automake17 openssl-devel subversion ncurses-devel -y

Configure Network Alias

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:1
Modify the file /etc/sysconfig/network-scripts/ifcfg-eth0:1 to look like this:

DEVICE=eth0:1
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.6
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes

Install Webmin / Virtualmin

* Import webmin pgp key:

wget http://www.webmin.com/jcameron-key.asc
rpm –import jcameron-key.asc

* Download the rpm:

wget http://prdownloads.sourceforge.net/webadmin/webmin-1.390-1.noarch.rpm

* Verify the rpm (should say OK or else download again):

rpm –checksig webmin-1.390-1.noarch.rpm

* Install the rpm:

rpm -Uvh webmin-1.390-1.noarch.rpm

Initial Webmin Config

We need to secure webmin by editing /etc/webmin/miniserv.conf and make the following changes:

* Using SSL only:

ssl=1

* Change the port to 443 and bind to the second nic only:

port=443
bind=192.168.1.6

* Disable UDP broadcasts:

#listen=10000

* Change host lockout on login failures to 3 :

blockhost_failures=3

* Increase host lockout timeout to 120:

blockhost_time=120

* Change user lockout on login failures to 3:

blockuser_failures=3

* Change user lockout timeout to 120:

blockuser_time=120

* Change the realm to something else:

realm=cpanel

* Log logins to utmp:

utmp=1

Install the webmin Tiger theme:

* Login to webmin via https://192.168.1.5:10000 using root and your password.
* Go to webmin ? Configuration ? webmin themes.
* Select From ftp or http URL and enter http://www.stress-free.co.nz/files/theme-stressfree.tar.gz
* Click install theme.
* Click “return to list themes”.
* Select StressFree as the Current theme then click change.

Install php-pear module:
Click Here!

* Go to webmin ? webmin configuration ? webmin modules.
* Select Third party module from and enter http://www.webmin.com/download/modules/php-pear.wbm.gz.
* Click install module.

Install virtualmin:

* Go to webmin ? webmin configuration ? webmin modules.
* Select install from ftp or http URL and enter http://download.webmin.com/download/virtualmin/virtual-server-3.51.gpl.wbm.gz

Remove unwanted modules Go to webmin ? webmin configuration ? delete and select the following:

* ADSL client
* Bacula backup system
* CD Burner
* CVS Server
* Cluster change passwords
* Cluster copy files
* Cluster cron jobs
* Cluster shell commands

Zen Cart Override Structure

By SteveK | Published: April 23, 2010

Zencart has a great override system. I’m currently setting up a Zen Cart website and loving this override system. The only improvement I see that is REALLY NEEDED is an ADMIN OVERRIDE. That would be terrific. Until then here’s a schematic of the current Zen Cart override system.
