Upgrading from Ubuntu 11.10 to 12.04 via command line

Posted by admin on May 16, 2012 in Uncategorized |

I’ve had nothing but problems upgrading from 11.10 to 12.04, googling it looks like a bunch of others are having the same issues. I recommend doing a fresh install instead.

 

Like any upgrade there’s a risk, make sure you backup your data if your concerned. Use these instructions at your own risk.

Find out what version of unbuntu your running

lsb_release -a

Output:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 11.10
Release: 11.10
Codename: oneiric

 

Now to upgrade run the following.

sudo apt-get install update-manager-core

sudo do-release-upgrade

sudo apt-get update && sudo apt-get upgrade

 

Output:

This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because it is harder to
recover in case of failure.

If you continue, an additional ssh daemon will be started at port
‘1022’.
Do you want to continue?

Continue [yN] y

If you click y and doesn’t go to the next stage like it didnt for me. Type in the command:

do-release-upgrade

Output:

Starting additional sshd

To make recovery in case of failure easier, an additional sshd will
be started on port ‘1022’. If anything goes wrong with the running
ssh you can still connect to the additional one.
If you run a firewall, you may need to temporarily open this port. As
this is potentially dangerous it’s not done automatically. You can
open the port with e.g.:
‘iptables -I INPUT -p tcp –dport 1022 -j ACCEPT’

To continue please press [ENTER]

 

Follow the prompts. If you have problems you can SSH into the port above. Use these instructions at your own risk. Size for my version above, it said around 900mb of updates and taking roughly an hour for the upgrade.

 

Hope these instructions help someone!

Making Ubuntu 11.10 run x11vnc on startup (solution/resolved)

Posted by admin on February 24, 2012 in Uncategorized |

SSH into the box. I use putty from a windows machine for ssh’n

Step 1:
Install x11vnc:

sudo apt-get install x11vnc

 

Set a password:

sudo x11vnc -storepasswd /etc/x11vnc.pass

This will prompt you for a password. This is just basic security and I recommend setting your firewall to only allow local access to your vnc server.
Step 2: Create the start up job for 11.10, this is different to previous Ubuntu versions.
Put this in /etc/init/x11vnc.conf :

To edit a the file type open up a text editor:

sudo nano /etc/init/x11vnc.conf

 

Type the following in:

start on login-session-start
script
/usr/bin/x11vnc -xkb -auth /var/run/lightdm/root/:0 -noxrecord -noxfixes -noxdamage -rfbauth /etc/x11vnc.pass -forever -bg -rfbport 5900 -o /var/log/x11vnc.log
end script

 

Press CTRL+X, Y to exit and save the file

Happy days

Making Telstra Bigpond 3G MF633BP some what more reliable

Posted by admin on February 4, 2012 in Project #2 - Make Bigpond 3G MF633BP more reliable |

Well like many others in regional areas, I went with the Telstra Bigpond 3G due to no access to ADSL. Satellite prices were about the same price however download limits weren’t the greatest with satellite compared to 3G(slightly better). At the time of searching for a company the options were very limited and other ISPs weren’t providing very good signal. So….. Telstra bigpond ended up being the choice.

The device which came was the MF633BP USB. http://www.zte.com.au/main/MF633BP.htm

So the fun begins!……..

Using the device within the house provided 2 – 3 signal bars, The original setup was Windows vista running the bigpond connection manager software with the latest drivers at the time. I would have to say, It was lucky to use the device for 10mins without a dropout or slow performance issues. It was like having a dial-up connection without the re-dial fee’s! something had to change.

 

Update: Havent finished writing this but I’m currently running it on ubuntu 11.10, PC starts up and automatically connects and shares the internet out.

Copper pipes

Posted by admin on July 15, 2010 in Project #1 - Pool Heater |

Quick and simple, I tried to buy the copper pipes locally however when first looking all prices were too expensive for short lengths. I ended up buying 18metres of 1/2 inch copper pipe on ebay from America. The shipping cost was something like $50 however as I was going over to America in a few weeks time I had it delivered for a small fee to my other half’s parents place. I don’t recall the exact price however it was around $35 AU

The heater

Posted by admin on July 15, 2010 in Project #1 - Pool Heater |

I was planning on using a gas cylinder or possibly two joined together with fire bricks on the bottom as the “heater” however I was struggling to find the sizes I was after. While searching I came across a Cast Iron heater for sale at Big W (wallmart). My sole decision on going with the cast iron heater was the hope it would last a lot longer then a custom made gas cylinder.

Pump Attempt #1 (fail)

Posted by admin on July 15, 2010 in Project #1 - Pool Heater |

For the pool heater I need a pump to pump the water from the pool through the copper pipes and back to the pool. First attempt I used a fish filter and removed all the filter options from the pump. However I was unable to get it to suck enough water up from the pool, it would work one mintue and not the next and when it did work it was very slow flowing. I was also put off as it was an AC device in water which would have people in it.  Before testing the pump I jumped ahead and tried to add the filter “plug” onto the end of the hose in the hope that I could add a small bit of hose to keep the AC pump out of the water. However with and without the hose ended in bad results. It just wasn’t powerful enough as the plan would be for the pump to pump it into a long hose.
