Networking in a Linux Environment Pete Eby Dan Thomas Robert Zurawski

Why Linux? 60% of web hosting is Linux based Linux is Open Source As effective as paid solutions Free to change for your needs – scalable Widely supported

Nagios Network Monitor Easy integration into existing networks GUI can immediately alert you to network errors Supports server, client, printer, and service monitor Can use environment sensors as well

Cacti Network statistics tool Uses Round Robin Archives MySQL & PHP Based – Customizable Robust and precise graphs Highly configurable Great network management tool

Nmap/Zenmap Network security auditing tool Find live hosts, report on any services that are running, detect the OS of the scanned system, and report on the version of the OS and services detected Strong port scanner Highly configurable Helps to harden your network from attacks

Iptraf Reports network traffic Supports a wide range of traffic including: IP, TCP, UDP, ICMP, IGMP, IGP, IGRP, OSPF, ARP, and RARP Interfaces supported: loopback, ethernet, FDDI, SLIP, Async PPP, Sync PPP over ISDN, ISDN IP encapsulation, ISDN Cisco HDLC encapsulation, and Parallel line IP Useful tool for determining what traffic is traveling on the network and where it is going

Mtr Combination of ping and traceroute Mtr reports: current, last, best, and worse latency, loss percentage, and sent packets to each hop that is taken to the destination Allows troubleshooting of any links that are down or might be running slow
