Abstract This guide provides an overview of many of the tools available for IP network administration of the linux operating system, kernels in the 2.2 and 2.4 series. It covers Ethernet, ARP, IP routing, NAT, and other topics central to the management of IP networks. List of Examples 1.1. Sample ifconfig output1.2. Testing reachability of a locally connected host with ping1.3. Testing reachabilit

Address Resolution Protocol (ARP) hovers in the shadows of most networks. Because of its simplicity, by comparison to higher layer protocols, ARP rarely intrudes upon the network administrator's routine. All modern IP-capable operating systems provide support for ARP. The uncommon alternative to ARP is static link-layer-to-IP mappings. ARP defines the exchanges between network interfaces connected

Software was once delivered as monolithic, fear-inducing, complex forklift upgrades, with database schema migrations, application updates, library updates, configuration updates and plenty of downtime. Sometimes, there was a gut-wrenching irrevocable critical step in the process (often a schema update). Today, this is largely a relic and bad memory now, thanks, in part, to Virtualization and Conta
