SSH (Secure Shell) is a well known protocol that allows remote execution of software but it can offer much more and we’re going to see how to use all it can offer. As a side note, in Linux’s world the most commonly used software implementation is OpenSSH (http://www.openssh.org). Enough theoretical stuff, we need action !
As much as I care about having open source software as much as possible, sometimes you find out that there’s no real good alternative for some of the proprietary software out there. Take Skype, for example. Everyone would like to have a Skype client on Pandora but it’s just not possible since it’s closed source. Dropbox is another example of an excellent application where no open source (and even closed source, for that matter) client is available for GNU/Linux ARM devices. Now since last week, we however have Bittorrent Sync. Not open source, but available for ARM Linux. Is it any good?
