My wife accidentally dropped her Macbook Pro off the sofa and broke the screen. Amazingly the computer was still running but she could no longer interact with it because the screen was completely blank. She was just finishing some work and didn’t have a backup. I think that the best thing to do in this scenario is remotely connect to the computer and rescue it. I don’t recommend restarting the computer because there is always a chance that it won’t come back up. You will need another working computers (preferably a Mac) to follow these instructions.
Here is how I did this:
1 – Open The Terminal On Broken Computer
Although, you can’t see the screen, you will need to open the terminal. You can open the terminal using the shortcut: command-space and typing terminal and pressing enter.
2 – Allow ssh connections
On the broken computer, you will need enable SSH. This requires some accurate typing because again you can’t see what you are typing. You need to enter this command (from within the terminal that you have just launched).
sudo systemsetup -setremotelogin on
3 – Find the computer’s IP Address
Using another computer, you will need to find the IP Address of your broken computer. The best way is to connect to your router and view the DHCP leases table. I can’t provide instructions for this stage because it varies so much between different routers. Here is how my Virgin router’s DHCP lease / reservation tables looked. I’ve covered over the mac addresses for privacy.
You can see the entry at the bottom shows a computer with an IP Address of 192.168.0.8. This was my wifes Macbook.
4 – SSH into the Macbook
From your working computer – you should then be able to SSH into the broken computer by opening the terminal.
ssh username@ipaddress
5 – Enable remote desktop
You should now be connected over SSH to the broken computer and should be able to enable remote desktop. This varies depending on the version of OSX that you are using. You can see full instructions on the Apple website. This is the command that I used:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -activate -configure -access -on -restart -agent -privs -al
6 – Connect Via Remote Desktop
You should now be able to connect the broken computer via remote desktop. The best tool that I’ve found for this job is Easy Remote Desktop. You open it and enter the IP address of the broken computer:
And voila…. you are connected to the computer…
I hope that this helps someone.
There isn’t a clear way to uninstall the Synology Cloud Station client on Ubuntu from the GUI. The only ways seems to be from the command line and it took me a while to find it.
Cloud Station is installed in your home directory in a hidden folder called ./Cloudstation. There is an uninstall script buried in a few folders down.
Open a terminal and run:
./CloudStation/CloudStation-app/package/uninstall
Job done.
I hope this helps someone.
I host a couple of WordPress sites on Ubuntu hosted on Digital Ocean droplets. I use their standard WordPress application (pre built WordPress on Ubuntu) with the smallest size Droplet possible. It has just 512MB Ram and 20GB SSD Disk and 1 logical core – i.e. it isn’t very quick.
Anyhow, I started to have a few problems with MySQL crash. I manifested itself by WordPress complaining that it could not connect to the database. I could fix the problem by restarting MySQL – ‘sudo service mysql restart’.
The longterm fix is to give MySQL more memory but I didn’t really want to do that. So, I opted to provide the server with more swap space. Given that Digital Ocean server are SSD’s this would be quite quick.
https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04
Here is how you add swap to an Ubuntu server:
1 – Check you what swap you have.
sudo swapon -s
If you get blank response then you don’t have any swap. Digital Ocean doesn’t seem to provide swap by default.
2 – Check how much disk space you have.
df -h
Filesystem Size Used Avail Use% Mounted on udev 234M 0 234M 0% /dev tmpfs 49M 528K 49M 2% /run /dev/vda1 20G 2.3G 17G 12% / tmpfs 245M 0 245M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 245M 0 245M 0% /sys/fs/cgroup tmpfs 49M 0 49M 0% /run/user/1000
I had 17G and so could easily give the server 1g swap.
3 – Use fallocate to reserve space on the file system. Fallocate is used because it doesn’t bother to write anything to the file system. It just allocates the space on the disk.
sudo fallocate -l 4G /swapfile
4 – Set file permissions
sudo chmod 600 /swapfile
5 – Convert it to a swap file
sudo mkswap /swapfile
6 – Add the swap
sudo swapon /swapfile
7 – Check that the swap is there
sudo swapon -s
8 – Add it to the fstab
so that it is mounted when the server reboots
sudo nano /etc/fstab
and put this line at the bottom:
/swapfile none swap sw 0 0
Finally, you can check it has all worked…
sudo swapon -s
Filename Type Size Used Priority /swapfile file 1194300 103160 -1
I am just installing Nagios on a Digital Ocean Droplet and wanted to know what specification server to purchase. According to the Nagios website the minimum requirements for Nagios are:
| Monitored Nodes | Hard Drive Space | CPU Cores | RAM |
|---|---|---|---|
| 50 – 250 | 40 GB | 1 – 2 | 1 – 4 GB |
| 100 – 500 | 80 GB | 2 – 4 | 4 – 8 GB |
I just visited the Headington Festival and saw the Headington Hillbillies playing. They were really good fun and played so great songs.
There was also a really cool classically jazz pianist with a portable piano.
The Headington festival was great fun and I’ll definitely be going next year.
I just discovered a nice little word count plugin which adds your the total word count for your WordPress site. I was really surprise to discover that I have written 23,700 Words over 3 years.
I’ve just launched a new website for our flat rental in Aberdovey called Aberdovey Sea Front Accommodation. We started to rent the flat last year and it has been going really well.
I’ve just been trying to buy a few hundred pallets and confusingly there seems to be licensed pallets and unlicensed pallets.
A licensed (or stamped) pallet is a pallet that has been made to a particular specification and is guaranteed to carry 1 ton. All licensed pallets are made in the same way, using the same thickness wood, the same number of planks, the same type of nails etc etc.
An unlicensed pallet will fit the size specifications but cannot be guaranteed to hold a ton. You can send an unlicensed pallet through a carrier (pallet network) no problem.
