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. IBM Corporation 2001 pSeries Technical Conference My Experience Unix user/admin for 16 years Self-Taught networking HP OpenView Certified Veritas NerveCenter Certified IBM Corporation 2001 pSeries Technical Conference Linux Networking "Recent changes in the areas of both software and hardware are combining to revolutionize networking." -- Marcio Saitio, Director of Technology Cyclades Corporation IBM Corporation 2001 pSeries Technical Conference Revolution Linux is positioned to ride the wave of the next revolution in the computer industry IBM Corporation 2001 pSeries Technical Conference Next Revolution Further integration of - Network Devices - Servers/Services No longer a clear definition between network and other devices Added functionality to network devices IBM Corporation 2001 pSeries Technical Conference Why Linux? Open Source Flexibility Security IBM Corporation 2001 pSeries Technical Conference Open Source Open Source is a key to the popularity of Linux today. IBM Corporation 2001 pSeries Technical Conference Open Source Open Source has allowed Linux to grow and expand beyond markets IBM Corporation 2001 pSeries Technical Conference Open Source Open Source has allowed Linux to become a fertile growing ground for new ideas IBM Corporation 2001 pSeries Technical Conference Open Source Has made Linux a popular "first port" platform for new embedded hardware. IBM Corporation 2001 pSeries Technical Conference Linux Flexibility Not locked to one protocol/stack Uses "common" Unix API's and interfaces IBM Corporation 2001 pSeries Technical Conference Linux Flexibility Ability to add and modify where needed/wanted IBM Corporation 2001 pSeries Technical Conference Linux Security Allow you to manage your own level of security IBM Corporation 2001 pSeries Technical Conference Revolution Examples IBM Corporation 2001 pSeries Technical Conference Example Linux Machines Router Web Server VPN Server Network Monitor Traffic Recorder IBM Corporation 2001 pSeries Technical Conference Packaged Software Solutions Linux Routers Linux Firewalls Linux VPN Servers Linux Data/Stats Servers IBM Corporation 2001 pSeries Technical Conference Example Linux Devices Linux Routers Cyclades Terminal Server Running Linux Sun Cobalt server IBM Corporation 2001 pSeries Technical Conference Linux Routers NetMax - www.netmax.com Linux Router Project - www.linuxrouter.org IBM Corporation 2001 pSeries Technical Conference Linux Data Collection/NMS MRTG on Linux Debian Telemetry Box Distribution www.debian.org/News/2001/20010125 IBM Corporation 2001 pSeries Technical Conference Tools for the Revolution IBM Corporation 2001 pSeries Technical Conference Revolution Tools Linux Kernel 2.4 Linux Kernel Devices Linux Kernel Software Server Network Applications Other IBM Corporation 2001 pSeries Technical Conference Linux 2.4 Kernel Improved TCP/IP IPTables NFS Version 3 Rewritten Firewall/NAT ATM Networking Kernel Web Daemon "Soft Net" IBM Corporation 2001 pSeries Technical Conference Device Support WAN Cards LAN Cards Wireless More...
