To change the keyboard layout on Lubuntu after you have installed the OS use:
setxkbmap -layout gb
I have come to the conclusion that I am a non specialist, I have many skills such as system admin, web site development, coding etc but have never had the time to become an expert in all but a few, the client or employer really just needs the job completed.
This could seem like a weakness but I have found over the years that the majority of projects require a wide skill base even if you are not a CSS guru even knowing the basics means that you can track the problem down and start to resolve it.
when I have put my project management hat on in the past having an overview of all the parts has been a massive advantage.
But for the few projects that do require very specific skills being able to talk the problem through with a guru once again give me an advantage.
My simple solution to monitor servers.
A friend of mine (yes I do have some) is the admin for a company that have a server room with lots of servers :-
- Windows file servers.
- Windows mail server running exchange.
- Linux server running their web sites.
- The list goes on………..
My solution to monitor these and report any problems was to use a Raspberry PI and a SMS module bought from Ebay, the PI also has a temperature and humidity sensor and runs a small internal web site.
A python script runs every minute and performs the following :
- Pings each servers network card.
- Attempts to connect to any special ports (SMTP, HTTP, HTTPS).
- Web scrapes several sites to check that they are up.
- Records the Temperature and humidity.
If there are any errors the PI attempts to email all the admins and me it will also send a SMS message to the admin users with a brief message.
Every day the PI Emails the admins with a basic report and a link the the data log.
Its has been running for 3 weeks now without any problems and has already detected several errors that normally would have gone unnoticed.
