  4. Linux Networking Linux is a powerful operating system and tool. One of the reasons for this is the flexibility of Linux Networking. We will look at what advantages Linux networking has, why Linux Networking has made Linux a powerful platform. Also we will look at what exciting advances are being made with Linux Networking that will rocket Linux into the future.

  5. My Experience Unix user/admin for 16 years Self-Taught networking HP OpenView Certified Veritas NerveCenter Certified

  6. Linux Networking "Recent changes in the areas of both software and hardware are combining to revolutionize networking." -- Marcio Saitio, Director of Technology Cyclades Corporation

  7. Revolution Linux is positioned to ride the wave of the next revolution in the computer industry

  8. Next Revolution Further integration of - Network Devices - Servers/Services No longer a clear definition between network and other devices Added functionality to network devices

  9. Why Linux? Open Source Flexibility Security

  10. Open Source Open Source is a key to the popularity of Linux today.

  11. Open Source Open Source has allowed Linux to grow and expand beyond markets

  12. Open Source Open Source has allowed Linux to become a fertile growing ground for new ideas

  13. Open Source Has made Linux a popular "first port" platform for new embedded hardware.

  14. Linux Flexibility Not locked to one protocol/stack Uses "common" Unix API's and interfaces

  15. Linux Flexibility Ability to add and modify where needed/wanted

  16. Linux Security Allow you to manage your own level of security

  17. Revolution Examples

  18. Example Linux Machines Router Web Server VPN Server Network Monitor Traffic Recorder

  19. Packaged Software Solutions Linux Routers Linux Firewalls Linux VPN Servers Linux Data/Stats Servers

  20. Example Linux Devices Linux Routers Cyclades Terminal Server Running Linux Sun Cobalt server

  21. Linux Routers NetMax - www.netmax.com Linux Router Project - www.linuxrouter.org

  22. Linux Data Collection/NMS MRTG on Linux Debian Telemetry Box Distribution - www.debian.org/News/2001/20010125

  23. Tools for the Revolution

  24. Revolution Tools Linux Kernel 2.4 Linux Kernel Devices Linux Kernel Software Server Network Applications Other

  25. Linux 2.4 Kernel Improved TCP/IP IPTables NFS Version 3 Rewritten Firewall/NAT ATM Networking Kernel Web Daemon "Soft Net"

  26. Device Support WAN Cards LAN Cards Wireless More...

  27. LAN Devices Ethernet 10/100/1000 Token Ring FDDI ATM Other...

  28. WAN Devices T1 CSU/DSU High Speed Serial Synchronous Serial HSSI T3 Other...

  30. Protocols IPv4 IPv6 DECNet ARCNet PPP (rewritten in 2.4) HDLC

  31. Kernel Software Masquarding IPChains/IPTables Kernel Daemons QoS Managment Specialized Soft Devices

  32. Masquarding/NAT An important key to Linux networking Really brought Linux to being a Router Is more flexible than other propriety solutions

  33. IP Tables/IP Chains IP Chains gave great control to admin IP Tables will continue that will added flexibility Port Forwarding Packet Filtering

  34. QoS TOS Support Packet Mangling Packet Filtering MAC address matching More....

  35. Kernel Daemons Khttp Knfs

  36. Kernel Http Daemon Strange but true Is a fast server

  37. Kernel NFS Better NFS support Supports NFSv3 Better user and file managment

  38. Specialized Soft Devices MultLink Devices VPN/Tunneling Devices Network Block Device PPP
