We are pleased to announce the latest NST release: "NST 18 SVN:4509". This release is based on Fedora 18 using Linux Kernel: "3.8.6-203.fc18". This is the most robust and stable release of NST to date. Significant effort has been devoted to integrate "systemd" service control support with all network services applications thus providing enhanced management and flexibility when using the NST WUI.
Here are some of the highlights for this release:
- Created a more friendly and intuitive user experience when booting NST Live and performing a Hard Disk installation.
- Added a new NST script: "nstipconf" which provides management to easily setup IPv4 Address and stealth network configurations in an NST system equipped with multiple network interface adapters for performing network surveillance tasks.
- Many new NST WUI enhancements and refinements including:
- The NST WUI network monitoring management pages (i.e., Nagios Core, Zabbix and Argus Monitor) have been refactored for ease of use, enhanced management and setup capability.
- The "Snort" network Intrusion Detection System (IDS) page now uses Barnyard2 integration for Unified2 IDS event data storage to the MySQL database.
- A new system SCSI storage device information page was added.
- SSH access using the Google Chrome Secure Shell has now been integrated into the NST IPv4 Tools widget. This allows SSH access using the Google Chrome Browser on any OS platform without the need to install a native SSH client.
- Many new NST Network Interface Bandwidth Monitor features including:
- Added a Query Update Rate Monitor.
- Significantly increased the query update rate performance.
- Added the ability to create two Custom Bandwith Monitors. This will allow one to simultaneously display network bandwidth rate graphs from two different network interfaces. This can be quite useful for displaying bandwidth network traffic at full line rates when using a non-aggregational network TAP (See the example network diagram below.).
*Each Bandwidth Monitor can now have its appearance customized using a NST Options Widget popup. One can adjust the background color and the color of each monitor graph. The opacity levels can also be adjusted on a per graph basis. These controls use to be global and applied to all monitors, but now they can be applied individually.
Now optionally collecting Bandwidth Monitor Data Rates when the monitor is hidden from view.
- Added clearer Threshold Pause State Change information in each status area.
A Threshold Pause Session can now be automatically enabled upon page load.
- The Bandwidth Monitor Background Color can change when a Threshold Pause Trigger Event occurs. This can be used in conjunction with the "Auto ReArm" option for a Visual Alarm Display when a Threshold Pause Trigger Event occurs.
- You can now download or export Bandwidth Monitor Data Rates as a CSV formatted file which can then be used by most data analysis applications.
- A new Threshold Pause Trigger Event Action has been added: The Bandwidth Monitor Data Rates can now be exported as a CSV formatted file to the NST system when a Threshold Pause Trigger Event occurs. A selection of Pause NICs and their associated data rate values can be included in the file.
- As always, the networking and security applications included have been updated to their latest version which can be found in the manifest.
