If you're running an online business like I am, there are times when you need to connect and log in to the server to tweak or check things. It can't be helped and while the Cpanel solution and related are often splendid, sometimes I just like to get bits all over my hands as I "go old school" on my server and use a command line.

In those instances there's a nice solution on the Mac called "Terminal", included with Mac OS X, and there's a rudimentary terminal window app for Windows too, but once you move onto mobile devices of any nature, nothing's available.

That's why I was so interested in iSSH [iTunes link], a low-cost iPad application that lets me connect directly to my Web server via a secure, encrypted connection (SSH = secure shell, it's the secure alternative to "telnet') from my iPad and, in case of a crisis, even my iPhone.

I have a Virtual Private Server or a dedicated server running Linux, but I'm not sure which version of Linux (Fedora, CentOS, Debian, etc.) the server is running. How do I find out?

Help! For some reason when I try to use "ssh" to connect to my server from my Mac, it fails and is saying that I might be a victim of a "DNS Spoof"? What's going on, and how do I fix the problem?
