PuTTY, WinSCP and VNC

VNC

VNC support is installed natively, it just needs to be configured. VNC is like Remote Assistance from Microsoft; you are able to remotely view and control Gnome and all open windows interactively. Of course there are a few limitations (such as applications relying on OpenGL). XBMC for example cannot be controlled via VNC.

1. From the Gnome System menu select preferences and then Remote Desktop

2. Configure according to your own security requirements. I wasn’t worried about limiting my exposure except for a password for inbound connections. Plus, I have a permimeter firewall; these boxes are not in a DMZ.

3. Install VNC viewer on the machine that you would like to connect from

4. Open VNC viewer on the machine you would like to connect from, insert the IP address of the remote machine and connect.

Tip: If Gnome Menus do not load, disable system effects (System, Preferences, Appearance)

PuTTY

First you need to install OpenSSH server on the remote machine

Put simply, PuTTY is software that allows you to run terminal commands/applications from a remote system. In other words, anything that is not GUI you can do remotely without VNC’ing to the box or logging into the physical box.

From Windows

1. Grab a copy of PuTTY; I prefer PuTTY portable

http://lmgtfy.com/?q=Putty+Portable

2. Open PuTTY.exe (or PuTTYportable.exe)

IP Address (or host) of server

Port 22

Username/Password

WinSCP

First you need to install OpenSSH server on the remote machine

According to the WinSCP website

“WinSCP is an open source SFTP client and FTP client for Windows. Its main function is the secure file transfer between a local and a remote computer. Beyond this, WinSCP offers basic file manager functionality. It uses Secure Shell (SSH) and supports, in addition to Secure FTP, also legacy SCP protocol.”

Put simply, WinSCP is software that allows you to upload files to and download files from your Linux server.

From Windows

1. Grab a copy of WinSCP; I prefer WinSCP portable

http://lmgtfy.com/?q=WinSCP+Portable

2. Open WinSCP.exe (or WinSCPportable.exe)

IP Address (or host) of server

Port 22

Username/Password

1. I installed OpenSSH server

sudo apt-get install openssh-server

2. That’s it; because I only have two accounts with very secure passwords, I wasn’t worried about limiting my exposure in any way. Plus, I have a permimeter firewall; these boxes are not in a DMZ.

For details on accessing the boxes using WinSCP and PuTTY see here

First you need to install Wine

1. Download the utorrent 1.8.2 setup file; do not download the latest version directly from utorrent, unfortunately it fails to open and says that uTorrent is already running.

http://lmgtfy.com/?q=utorrent+1.8.2+download

From Wine Utilities I seleted drive, added a new drive (e:), then mapped it to /dev/md0

1. Add the nvidia repo

sudo add-apt-repository ppa:nvidia-vdpau/ppa

2. Update to find the latest packages

sudo apt-get update

2. I created a backup of the original Samba configuration

cd /etc

cd samba

sudo mv smb.conf  smb.conf.old

I didn’t learn to do this by choice! I mucked up my video configuraiton and couldn’t boot into the gnome… after spending about 4 or 5 hours trying to fix it; I “bit the bullet” and reinstalled ubuntu.

1. I installed mdadm

sudo apt-get install mdadm

2. I (re) assembled the array

sudo mdadm –assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1

3. I got the details of the array

sudo mdadm –detail –scan

Output on this occasion was as follows; do not copy and paste this directly – it will be a different UUID for future arrays I create

ARRAY /dev/md0 level=raid5 num-devices=6 metadata=00.90 UUID=58155936:66553965:01f9e43d:ac30fbff

I found out later that I needed to remove one of the zeroes from the metadata version… when I did a sudo mdadm -D it gave me an error for the version information.

ARRAY /dev/md0 level=raid5 num-devices=6 metadata=0.90 UUID=58155936:66553965:01f9e43d:ac30fbff

4. I copied and pasted the above line into mdadm.conf

sudo nano /etc/mdadm.conf

File now has the following entry:

# definitions of existing MD arrays

ARRAY /dev/md0 level=raid5 num-devices=6 metadata=0.90 UUID=58155936:66553965:01f9e43d:ac30fbff

5. I created somewhere for the array to be mounted

cd /mnt

sudo mkdir raid

6. I wanted the drive to be mounted automaticaly on startup

sudo nano /etc/fstab

7. I added the following line

/dev/md0                /mnt/raid                ext3                defaults                0                0

8. I mounted all arrays without rebooting

sudo mount -a

Originaly found here http://www.jamierf.co.uk/2009/11/04/software-raid-5-using-mdadm-in-ubuntu-9-10/ but stored on my blog for reference incase their blog dies one day.

1. I installed mdadm

sudo apt-get install mdadm

2. I listed all the drives

sudo fdisk -l

3. I edited each drive that was to be part of the array, for me my system drive and spare drive was /dev/sdg and /dev/sdh respectively

sudo fdisk /dev/sda (but I also did this for the other drives in the array) /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf

4. I edited each drive that was to be part of the array, for me my system drive and spare drive was /dev/sdg and /dev/sdh respectively so obviously I didn’t touch them

n (for new drive)

p (for primary partition

1 (for partition 1)

enter (to select first cylinder

enter (to select last cylinder)

t (to set disk type)

1 (for partition 1)

fd (for Linux Raid Autodetect)

w (to write changes to disk)

5. I created the array

sudo mdadm –create –verbose /dev/md0 –level=5 –raid-devices=6 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1

6. I watched the progress

sudo mdadm -D /dev/md0

7. I got the details of the array

sudo mdadm –detail –scan

Output on this occasion was as follows; do not copy and paste this directly – it will be a different UUID for future arrays I create

ARRAY /dev/md0 level=raid5 num-devices=6 metadata=00.90 UUID=58155936:66553965:01f9e43d:ac30fbff

found out later that I needed to remove one of the zeroes from the metadata version… when I did a sudo mdadm -D it gave me an error for the version information.

ARRAY /dev/md0 level=raid5 num-devices=6 metadata=0.90 UUID=58155936:66553965:01f9e43d:ac30fbff

8. I copied and pasted the above line into mdadm.conf

sudo nano /etc/mdadm.conf

File now has the following entry:

# definitions of existing MD arrays

ARRAY /dev/md0 level=raid5 num-devices=6 metadata=0.90 UUID=58155936:66553965:01f9e43d:ac30fbff

9. I created the file system

sudo mkfs.ext3 /dev/md0

10. I removed the default 5% reserved space from the drive

sudo tune2fs -m 0 /dev/md0

11. I created somewhere for the array to be mounted

cd /mnt

sudo mkdir raid

12. I wanted the drive to be mounted automaticaly on startup

sudo nano /etc/fstab

13. I added the following line

/dev/md0                /mnt/raid                ext3                defaults                0                0

14. I mounted all arrays without rebooting

sudo mount -a

sudo fdisk -l
