2 Agenda 1. Presenta*on: Virtual Appliance overview 2. Demo: acquire / deploy virtual appliance 3. Demo: brief overview of included tools sample network (Cisco VIRL) 4. Support / contact informa*on 5. Q & A 2 8/18/15

3 Challenges of Network Management 3 8/18/15

4 Network Management Challenges n Why is my network so slow? n Do I have enough network capacity to meet demand for this BYOD / 1:1 project? n I just pasted a switch config into the wrong terminal window! Hope I have backups! 4 8/18/15

5 Network Management Challenges (contd.) n I wish I could get alerts when the portable air conditioner in my server room stops working! n It would be nice to get alerts from my UPS units when the power is out for more than 30 minutes. n I need to find out who is using BitTorrent on my network. n I don t think my WAN provider is giving me the bandwidth I m paying for. 5 8/18/15

6 Virtual Appliance Overview n What is it? n Tools Included n What can it do? n What can t it do? n Why Virtual? 6 8/18/15

7 What is it? n Virtual appliance with pre-configured open-source network monitoring tools n Includes open-source tools for: Realtime Network Performance Analysis Historical Network Performance Monitoring Network Status Monitoring (Alerts) Network Troubleshooting 7 8/18/15

8 What is it? (contd.) n Available as a virtual package (OVA) that can be deployed on your local machine or virtual infrastructure n A good solution for those needing to quickly evaluate the included tools n An all-in-one package to facilitate monitoring small networks 8 8/18/15

9 Tools Included n NDT n IPERF n NTOP / NTOPNG n Cacti n SmokePing n Nagios 3 n NCONF n Webmin n Web-based Console n TSHARK n NMAP n MTR n RANCID / ViewVC 9 8/18/15

10 What can it do? n Realtime Network Performance Analysis NDT Server / Client (TCP throughput testing) IPERF Server / Client (TCP / UDP throughput testing) NTOP / NTOPNG (Identify top flows on the network, usually to and from the Internet) n Network Performance Data Collection (Historical) Cacti (SNMP Polling / Graphing Tool; Bandwidth & Utilization Graphing) 10 8/18/15

11 What can it do? (contd.) n Network Performance Data Collection (contd.) SmokePing (poll / graph network latency / loss) n Alerting Nagios 3 (up / down monitoring and alerts; availability reporting) n Configuration Management / Backups RANCID (Really Awesome New Cisco config Differ) / ViewVC (configuration archiving / revision diffing / annotation tool) 11 8/18/15

12 What can it do? (contd.) n System / Tool Configuration (contd.) Webmin (Linux system GUI config tool) NCONF (GUI Configuration tool for Nagios 3) Web Console (shellinaboxd) n Network Troubleshooting Tools TSHARK (command-line version of Wireshark) NMAP (Host / Service Scanning) MTR (monitor traceroute hops with ICMP) 12 8/18/15

13 What can it do? (contd.) n Web-based menu UI to access tools and documentation n Inline documentation of command-line tools with examples n Easy access to official documentation of tools via web menu UI n Easy access to MCNC Resources (contact info, website, K-12 Landing Page) from web menu UI 13 8/18/15

14 What can t it do? n Provide full performance for throughput testing tools like NDT and IPERF (due to the virtual networking stack) n Provide full performance for utilities that capture packets to analyze data like TSHARK, NTOP, or NTOPNG (due to the virtual networking stack) n Not recommended for permanent / production use as a syslog server storing, indexing, and analyzing large quantities of syslog messages is outside this project s scope 14 8/18/15

15 Why Virtual? n Consistent deployments; easier to support n Capitalize on virtualization features such as Portability Snapshots Cloning n Facilitates taking the included tools for a test drive without having to manually install / deploy them 15 8/18/15

16 Acquisition Methods n Download OVA file from Google Drive link provided n Download Clonezilla image from Google Drive link provided for physical hardware n Request CNE assistance for deployment n Request during Network Health Assessment (we will provide your Assessment tool configurations) n Utilize MCNC CNE Probe Build Service 16 8/18/15

17 Google Drive Download n Updated OVA image for VMWare available later today (1 st revision for Virtualbox is already available for download) n Updated Clonezilla restore ISO / image coming soon (1 st revision already available for download) n Quick Start and Clonezilla Guides available n /18/15
