would be nice to present the difference between IKEv1 and IKEv2

I'm nine years late, but thank you for sharing this video! I was struggling with understanding how the dynamic routing protocol fits into DMVPNs and NHRP and this video helped me greatly.

Almost wish TTL had an option like sending it with a -1 so it generates the ICMP message on each hop but still continues towards destination.

Hi Jack, yes I have a CompTIA Network Plus course published through Pearson IT Certification. It's available to the public but also included in many university and public education programs. Maybe for free through your library if in the US. www.pearsonitcertification.com/store/comptia-network-plus-n10-008-complete-video-course-9780137507412

The ICMP wiki page has been updated to say it is Layer 3. "ICMP is a network-layer protocol, this makes it layer 3 protocol by the 7 layer OSI model." and "There is no TCP or UDP port number associated with ICMP packets as these numbers are associated with the transport layer above." -- What are your thoughts today on this?

@RyanLindfield Жыл бұрын

There is a lot of bad information out there, thanks for asking. All ICMP messages (ping , mtu , redirect etc) are included withing a header (ICMP) which is carried within (encapsulation) an IP header. ICMP, IGMP, TCP, UDP, OSPF, GRE are all alike these are messages carried by IP,. Layer 4 goes into Layer 3, always. Check out how many layer 4 protocols exist it's wild :) www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml

Als SSL-VPN (englische Schreibweise: SSL VPN ohne durchkoppelnden Bindestrich) bezeichnet man Systeme, die den Transport privater Daten über öffentliche Netzwerke ermöglichen (siehe VPN) und als Verschlüsselungsprotokoll TLS (alte Bezeichnung: SSL) verwenden. Prinzipiell ist SSL als Verschlüsselungsprotokoll für VPN sowohl für Site-to-Site- als auch End-to-Site-VPNs geeignet. In den 1990er-Jahren gab es Systeme, die SSL als Sicherungsschicht für Site-to-Site-VPNs einsetzten. Mit der Entwicklung von IPsec und der zunehmenden Vernetzung über Organisationsgrenzen hinaus hat das standardisierte, interoperable IPsec sich als Alternative etabliert. Der entscheidende Vorteil von SSL-VPN gegenüber IPsec ist die Bereitstellung des Netzwerk- und Applikationszugriffs für mobile Anwender, da die Konfiguration der Clients einfacher möglich ist als mit einer Lösung durch IPsec. de.wikipedia.org/wiki/SSL-VPN

zenmap, nmap and visualtraceroute are very useful tools that can be used to have resources to deflect a lot of these hacking technologies that are out there. zenmap / nmap can help "map" out on how certain services may work through the internet and how they interconnected. visualtraceroute will assists on locating on where the service may be hosting at geographically and studies on how the communication works with delay if there is.
