The cool thing here is that we only need 1 drive to make a RAID 10 or RAID 1 array, we just tell the Linux mdadm utility that the other drive is "missing" and we can then add our original drive to the array after booting into our new RAID array.
Step#1 Install tools we need
yum -y install mdadm rsync
Step #2 Create your partitions on the drive that will be our RAID array
Here I assume it is /dev........
One simple way to keep your server public but almost impossible to hack via SSHis to disable password authentication over SSH. This means the only way in is via your own private key that only you should have.
Edit your /etc/ssh/sshd.conf file
Set this option
PasswordAuthentication no
Restart your SSH server.
service sshd restart

The solution is simple but strange, if you copy your /var/lib/mysql directory to another server and think it will work, be sure to check if you have /var/log/mysql and binary log files. If you do, the server will not work and will give you errors like below and crash without the proper log files.
UPDATE user SET password=password("newpass") WHERE user='root';
flush privileges;

Here is the scenario you or a client have a remote machine that was installed as a standard/default minimal Centos 6.x machine on a single disk with LVM for whatever reason. Often many people do not know how to install it to a RAID array so it is common to have this problem and why reinstall if you don't need to? In some cases on a remote system you can't easily reinstall without physical or KVM access.
So in this case you add a second physical or disk or already ha........
I was worried the server was hacked, I was logged in already as root but couldn't login to CPanel or a new SSHsession. I even reset the password from the shell and it did not work still.
The reason is CPanel Hulk, it detected a brute-force attack so it locked down the root account entirely even from the correct password. According to cPanel the best way around this is to whitelist your IP.........

Here is a quick script that works on most Centos versions to disable the virus/SELinux from blocking basic functionality.
The first echo 0 statement disables SELinux instantly but it will still be enabled on reboot.
The second line disables it permanently.
#!/bin/bash
#disable SELinux Immediately
echo 0 > /selinux/enforce
#disable SELinux Permanently
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config........
I searched for days after getting my Galaxy Note and couldn't find a way to do this (at least not without buying programs for either Android/Windows). All I read was ways to sync and import the contacts to GMail but I don't want to use GMail for privacy reasons. GMail/Google steal all of your personal information and use it for whatever purposes they want to and may sell or release it to who knows where (I don't care what their policy says but this stuff happens), just like the default........
This is a very simple solution, but most guides out there make you login twice (once to scp the key) and once to put the key in authorized_keys. There's no need for that.
If you don't already have a ~/.ssh/id_rsa.pub just type "ssh-keygen -t rsa" and keep hitting enter until it's done :)
Just use this code to easily enable passwordless login with SSHD
key=`cat ~/.ssh/id_rsa.pub`;ssh user@192.168.5.25 "echo $key >> ~/.ssh/auth........
./ntfs-3g /dev/sda1 /mnt -o force
Unexpected sectors per cluster value (127).
Failed to mount '/dev/sda1': Invalid argument
The device '/dev/sda1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
This is happening on a system I've come across an HP 6930P running Windows XP Professional. The partition appears to be very norm........
Telus Begins Enforcing Bandwidth CapsIt appears Telus has begun to send e-mails out and is planning on enforcing bandwidth caps of only 10gigs/month for their 1.5mbit plan and 20gigs/month for 2.5mbit
The state of Canadian ISPs is horrible :(
In the east coast, Bell Sympatico will allow you to have unlimited bandwidth and even Aliant will and they have 3mbit for a much more affordable price than our 2.5mbit on Telus.
Telus needs to get wit........
Yes, Iadmit I finally got bitten by the hype as much as I can usually see through it all. Keep in mind this review is of the "stock" phone, no jailbreaking yet which is what really unleashes the customizability and whyI bought iPhone.
I had better things to say about this phone before buying it, and it is a great phone, perhaps the best on the market by far, if not because of the Mac OS port onto the iPhone and all the apps, etc, etc.
With that said........
