+ | ==== Speedup login by using ssh keys ==== | ||
+ | |||
+ | An alternative method of authenticating via ssh is by using ssh keys. | ||

+ | ==== How not to loose all your job because you closed a ssh terminal ==== | ||
+ | |||
+ | Use **screen**. //GNU screen// is an amazing tool that opens a remote terminal that is independent on your ssh connection. If the connection drops or you accidentally close the ssh window, it will still run your jobs on the cluster. | ||
+ | |||
+ | A quick and dirty tutorial can be read [[:it_tips#screen|here]], but there's plenty more on the internet. | ||
