On Android devices, ConnectBot by Kenny Root and Jeffrey Sharkey is probably the best choice at this time (Figure 3).įigure 3: SSH with ConnectBot (from the developers’ website). If you frequently manage Unix and Linux servers, your primary tool is going to be an SSH client. Setting up this connection is described for Android and iOS elsewhere. Most systems are not exposed to the Internet without protection but are, instead, well hidden behind a firewall, so access can only be made via a VPN connection in most cases. Additionally, a variety of tools sprinkled throughout the web make life easier for IT professionals.

If you rummage through the Google Play Store or Apple’s App Store, you are likely to find a large number of mostly free apps that help sys admins manage the systems they support in a reasonably convenient way while using a fairly small mobile device. A current, reasonably secure Android with VPN is a must-have in this case. On the Apple front, we had access to an iPhone with iOS 6 and a first-generation iPad with iOS 5 – again, with no compatibility issues (Figures 1 and 2).įigure 2: Even elderly devices like the HTC Desire Z, which is several years old, can be used for quick admin work on the go. None of the tested programs had compatibility issues on any of the devices. Smartphones and tablets with sufficiently large screen sizes are mutating into multifunctional tools that can do most of the important tasks while on the road or in an emergency.Īndroid devices are not characterized by any kind of version homogeneity, so we decided to test the programs on various devices: a Nexus 4 with the latest Android 4.3, a Nook HD+ with a slightly older version of Android 4, an ancient Motorola Defy with Cyanogen Mod 7 Android 2.3.7, a Sony Experia with Android 2.3 and many backports by the manufacturer, and an HTC Desire Z with Android AOSP 4.2.2. In the pre-smartphone era, which was not so long ago, it was hard to imagine a practical use for a mobile device in system administration – if you discount laptops with graphical and web interfaces or terminal software designed for high latency.Īll that has changed: With ubiquitous broadband and mobile data connections and with hotspots and WLANs widespread in the enterprise, admins are increasingly able to leave their desks and get out of the server room.
