A good diagnostic tool for any sysadmin is a port scanner to ensure a firewall is working as intended to open or close ports. When you want a quick and dirty scanning tool, there are some great free apps in the Market to do the trick. A quick search in the Market shows two apps which seem to be popular: OscanO and Port Scandroid.

Port Scandroid

This free app in the Market was written by Rich Jones of NewFreedomApps, found at http://www.thenewfreedom.net/ and the app is described by the author like this:

Port Scandroid is a port scanner for Android.

Apple iOS 3 & 4 VS Android 2.1

In This Corner!

For better or worse Apple has dropped their latest update regarding the groundbreaking iPhone this week along with the official release date for their next version of the phone’s operating system, which has now been dubbed ‘iOS’.

Apple iOS 3 & 4 VS Android 2.1 "Eclair" & 2.2 "Froyo": Fight!

A big thanks to Ian Douglas for all the work he did putting the chart together, and to my fiancee for the image

The announcement comes on the heels of last Friday’s uber-successful launch of the Sprint EVO 4G, which shares many of the same features with the new iPhone.

UK readers only: if you like adorable handsets running an operating system with an adorable mascot or, and perhaps more importantly, if you like free things, then you owe the X10 Mini a few minutes of your time.

It’s not the most powerful Android handset on the block, and hell, it’s not even running Android 2.1, for an attractive, and again, free, Android handset, it’s not a bad deal.

Of course, as with most free phone offers, it will require you to sign your soul away for two years with a new contract, but on the bright side, you have your choice of four carriers to deal with.

Nagios is by far one of the best solutions for monitoring just about everything on a server, and it’s excellent API system means that anything it doesn’t include out of the box can be written in just about any programming language as long as the program output conforms to their standard. I’ve personally written dozens of modules for micro-managing network interfaces, disk IO and so on. I’ve even heard of elaborate schemes of detecting when system load is too high on web servers and launching more Amazon EC2 instances, or checking when load is low enough to terminate EC2 instances, all fully automated.

Rooted EVO 4G Users Can Now Enjoy Unlimited Free WiFi/Bluetooth Tether (Hotspot) As Android-wifi-tether App Adds Support For EVO
Last Updated: June 12th, 2010

EVO 4G users, rejoice! As of a few minutes ago, you can enjoy unlimited free WiFi/Bluetooth tethering using the Wireless Tether for Root users (or simply android-wifi-tether) app.

The app's main committer Harald Mue, who doesn't even have the EVO in his possession, together with a community contributor Andrew Robinson (who does have one) have figured out what was going wrong with the EVO compared to other phones and together collaborated on a fix all within 2 days of finding the problem

Hey, wait a minute, wasn't the EVO released the same 2 days ago?

This article mentions rooting and the flashing of non-stock roms. If you’re unfamiliar with either term, hit up our primers here and here for additional information

Good news for those of you that were hoping to root your EVO the minute you tear it free from the box: the instructions and files needed in order to root the device have been officially released online.

User ‘toastcfh’ over at XDA-Developers, who’s been providing us with teaser images and video of his rooted EVO for the last couple of weeks, has come clean with detailed instructions on how you can get sweet, sweet root access on your EVO.

Decaf by 9Apps
Last Updated: July 24th, 2011

Welcome back to the SysAdmin Series, where we pick apart another app geared towards system administration. My apologies for missing Sunday’s post, a family emergency kept me offline most of the weekend.

One of the very first apps I installed on my Nexus One when it arrived in February, was Decaf by 9Apps; it was also the first paid app I bought for my Nexus One. They’ve played with their pricing scheme over time – I bought the app for 4.99 Euros mid-February, they raised the price to 9.99 Euros a month later, then up to 24.99 Euros a few weeks ago, before settling on the current 19.99 Euros price.

Forget Using Your HTC EVO 4G's Screen As A Flashlight - Use Its Blinding Dual LED Flash Instead
Last Updated: June 6th, 2010

The EVO 4G, which is coming out in only 2 days on June 4th, comes with a pretty decent 8MP camera. One of the best things about the camera is that it in turn comes with a shockingly bright for a cell phone dual LED flash. Here it is:

Forget Using Your HTC EVO 4G's Screen As A Flashlight - Use Its Blinding Dual LED Flash Instead

Wouldn't it be perfect if you could use these LEDs on demand, turning the EVO into a bright flashlight? You can do that with some other phones, and EVO's little sister HTC HD2, which has essentially the same body but runs WinMo, even includes a native app to do so.

Our friends over at Engadget have published a kick ass guide on how to take advantage of Froyo’s cloud to device messenger capability. You may recall the demonstration during the Android keynote at Google I/O, where they pushed directions to their phone from Google Maps with the click of a button. Well, someone hacked together a quick app and accompanying Chrome and Firefox extensions that will allow you to do the same.

Welcome to the new SysAdmin Series, where we will cover apps and other tips and tricks for using your Android device to help you get the job done and stay on top of things in the realm of system administration.

Probably the foremost tool for any sysadmin is a good SSH client. My favorite so far is ConnectBot, by Kenny Root and Jeffrey Sharkey. At the time of this writing, this free, lean, simple SSH client is at version 1.6.2, weighs in at 352KB and has had more than 250,000 downloads and enjoys a 5-star rating from over 10,000 users, and describes itself as such in the Android Market:

ConnectBot is a powerful open-soure Secure Shell (SSH) client.
