Is it possible to dual boot from a USB flash drive? Also is it possible to boot the operating system from an ISO image (like the Ubuntu Live CD)?
How would you go about doing this and what software would be needed?
When compared to a 'real' server does a cloud-hosted virtual server of a similar specification (available RAM, processer, disk etc) have a noticable performance cost?
I would like to shrink the size of a partition containing an Ubuntu distribution and files. Is it safe to assume that I will not lose or corrupt any of the files as long as I don't make the partition smaller than the amount of data that is currently on it? I am planning to use GParted from the Ubuntu LiveCD.
I have two servers, one a development server that is accessible internally on our company's local network and the other a public-facing web server. The development server hosts several tools that we use to manage our projects internally but now we need to access them externally too whilst maintaining security.
I have set up mod_proxy on the external server using the ProxyPass and ProxyPassReverse directives to map external requests to the internal server. I have also set up authentication on these external virtual hosts to provide security for outside access. I also need to use SSL for external access but would ideally prefer to keep the internal tools accessible by plain HTTP for people within the intranet.
Is it possible to achieve this behaviour and if so what directives and Apache modules should I be using and on which servers do they need to be setup?
