Over at The Complete Geek my friend Jered posted a really nice howto on remote X11 forwarding the other day.

Like uses of Synergy, remote X can be extremely useful when you’re working with multiple machines, or even if you’re working with a virtual machine and need to run some of the applications on the host without constantly flipping windows back and forth.

xclip is a command line interface to the X11 selections (X11 clipboard). It can also be used for copying files, as an alternative to sftp/scp, thus avoiding password prompts when X11 forwarding has already been setup. xclip reads from Standard Input or from one or more files and copy it to the X11 clipboard making it available to the X applications.

Full screen ncurses and X11 traceroute tool.mtr combines the functionality of the ‘traceroute’ and ‘ping’ programs in a single network diagnostic tool.
