Join Greg Sowell for an in-depth discussion in this video SMB, part of Networking Foundations: Protocols and CLI Tools.
- [Voiceover] Server Message Block is an application…layer protocol for sharing files,…printers, and serial ports.…It can run directly on TCP port 445,…which is how it's most often used.…It can also run on Legacy NetBIOS,…but it's seldom seen doing so.…It's best known as a mechanism…behind Windows file sharing.…SMB 2.0 was released in 2006 with Windows Vista.…The supposed chattiness of the protocol was reduced.…
They took the volume of commands…from over 100 to just 19.…Multiple commands can be submitted in a single request,…further increasing efficiencies.…The block size was also increased…from 16-bit to 128-bit, in some cases,…which improves performance for large file transfers.…SMB 2.1 was introduced with Windows 7…and Server 2008 RC2.…This brought some performance enhancements.…SMB 3.0 shipped with Windows 8 and Windows Server 2012.…
This saw additional performance boost,…as well as some new functionality.…Additional security enhancements were seen,…including end-to-end encryption,…which was introduced using AES signing.…
Protocols are the lifeblood of modern communication. By the end of this course, you'll know what you need to troubleshoot any network connection and keep the communication flowing.
Note: This course maps to domain 3 of the MTA Networking Fundamentals exam.
- Identify reasons why connectionless transmissions are faster.
- Determine what type of attack a gratuitous ARP announcing itself as a legitimate host indicates.
- State what IGMP snooping is useful for.
- Describe the best approach to use FTP to view and rename files on a server when your client is behind a firewall.
- Assess whether SSH is natively supported on Windows or not.
- List good uses for the arp command.
