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.

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.

My Backup Pro For Google Nexus 7 Won’t Accept Email & Password

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.

Developer Options Not Showing On Google Nexus 7 Android Version 4.2.1 Build JPO40D

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.

Google Calendar – Can Only Share Calendar In See Only Free/Busy (Hide Details) Mode

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.
