The dnsenum.pl Perl script as described in its Perl documentation is a multithreaded script to enumerate information on a domain and to discover non-contiguous IP blocks. So the gist of dnsenum is to gather information about a specific domain using various sources. Information gathered about a domain includes sub domains, associated IP ranges, name servers, mx records, reverse DNS records, hostname IP addresses, and potential vulnerabilities via zone transfers. Below we go into detail regarding the switches available with dnsenum as well as what the command returns by default without and CLI switches.
I downloaded My Backup Pro to use as a secondary backup on my Google Nexus 7 device which is running Android 4.2. When attempting to configure the the email address and password associated to the My Backup Pro account it continued to reject the information I was providing. Initially I thought the password must be too long, which it was, but even after shortening it to the allowed fifteen characters it continued to reject my settings. It ended up being the email address I used not being accepted because it included a “-“. Below I describe a bit more and provide a screenshot of the screen in question.
I have never had an Android device before so pretty much everything is new to me at this point. I will be writing a bunch of articles regarding the basics of Android and more specifically the basics of Android 4.2 on a Google Nexus 7. In the process of working to root the Nexus 7 I needed to backup everything on the Nexus 7 device including everything that has been configured to date. I also have taken a bunch of screenshots that I wanted to make sure got backed up before I proceed with rooting it. Backing up the Google Nexus 7 is easy but there are a couple steps to make sure you get everything which I have outlined below.
I just started getting a little time to play around with my new Google Nexus 7 32GB tablet and so far I am loving it. It will be the first Android device that I have spent much time on so its pretty exciting! I love the size of the Nexus 7 because it still fits in my pocket and will be perfect to read or watch movies while flying around the country. Obviously the first thing I wanted to do was root the Nexus 7 so I could have full control of it but the Developer Options setting was missing from my Android 4.2.1 Settings screen. Below I show an image of my default Android Settings screen and explain how to display the Developer Options menu item in Settings.
This morning I was attempting to share one of my Google Apps Google Calendars with my default Gmail account with full access rights however it kept changing the sharing mode from Manage Changes and Manage Sharing to See Only Free/Busy (Hide Details). At first I thought it had to do with the calendar I was sharing too already being shared back to this calendar with lower calendar event rights however after I deleted all traces of the calendar I was still running into the same issue. Turns out the issue was in the Google Apps dashboard for the Google Apps Calendar I was attempting to share to the normal Google account. Below I describe the issue in more detail and what settings need to be modified in the Google Apps dashboard to allow you to share Google Apps Calendars with full admin privileges.
