November Newsletter Published

This newsletter talks about the changes in NetScanTools Pro 10.94 in detail. It covers new record types that it can retrieve: NSEC, DNSKEY, RRSIG and the new Get Basic DNS Records tool. There is also a discussion about using the Passive Discovery tool and the changes made to make it easier to use.

There is a status report on NetScanTools LE (law enforcement edition).

I added in a paragraph about my experience upgrading a computer from Windows Vista x64 to Windows 7 x64. It was actually pretty painless. And it even worked!

The newsletter can be found on this page:

NetScanTools (TM) Pro 10.94 USB Version Patch Ready

I should have posted this a couple days ago, but for those of you who are NetScanTools Pro USB Version users, the patch to upgrade to the latest version 10.94 is ready. You will need an active maintenance plan to access the patch. Login through Help/Check for New Version.

NetScanTools Pro USB Version is a fully portable software application that runs from a USB flash drive. It is self-contained and does not require installation on the target computer. All data is saved on the USB drive and not saved to the hard drive of the computer hosting it. NetScanTools Pro USB Version runs on Windows 7, Vista, XP, and 2000. It runs on both the 64 and 32 bit versions of the operating systems and is a 32 bit application itself.

Right now we are having a sale. Get the installed version on CDROM and the USB Version for the price of the USB Version. More details:

NetScanTools (TM) Pro 10.94 Published

The installed version of this release was posted on November 2. This release is geared towards improved Windows 7 compatibility.

It now includes the latest version of WinPcap 4.1.1 (just released last week) which has been extensively tested on Windows 7. NetScanTools Pro uses WinPcap for packet capture and generation of specialized packets. Previously we used 4.0.2 which seems to work fine on Windows 7 for our purposes.

We've also updated the SQLite DLL to the latest version 3.6.19 and made it statically linked to avoid SxS DLL problems.

Feature-wise there are several changes to the "DNS Tools-Core" toolset. There is a new tool called "Get Basic DNS Records". This tool requests SOA, A, NS, MX, CNAME, PTR and TXT resource records as applicable for a given input IP address, hostname or domain name. It saves time by combining all those queries into one query.

DNS Tools - Core also now includes options for requesting the NSEC, DNSKEY and RRSIG resource records. We have had the ability to parse those records for awhile, but now you can directly request them and the parsing has now been significantly improved. When parsing NSEC, we added showing the list of resource records (RR) covered. In DNSKEY we added display of the public key as hex and also now also compute and display the Key ID. The Key ID can be correlated with the corresponding Key ID from the RRSIG records. The RRSIG record parsing was improved by adding display of the signature in hex and we now parse many more "types covered".

DNS Tools - Core also had a problem when doing a Zone Transfer of a medium to large zone. They would crash the program. This was due to a memory allocation error and also due to the fact that in C "static int x = 0;" is not reset to zero when the function is re-entered.

Passive Discovery has a change which is more user related. We had heard from people who saw a "Error compiling filter" when they tried to run it. This was due to a mismatch between the WinPcap interface they selected, the subnet mask and the starting network IP address. We are no longer saving the subnet mask and starting IP, they are being recalculated. We also reworded the Recalculate button to better explain what it does and we improved the error messages.

There were some other minor changes but I won't go into those. As usual the database were updated. If you have NetScanTools Pro with an active maintenance plan, click on Help/Check for New Version to get 10.94.
