Natty Narwhal Netbook: Ultimate Network Admin Toolkit
Natty Narwhal's baked-in software
There is a wide range of networking software included in the default Natty LiveCD image, so you don't have to install them. These break down into several useful categories.
* bind9-host helps with DNS lookups.
* dnsutils provides the dig DNS querying command, nslookup (deprecated DNS query), and nsupdate for dynamic DNS updates.
* isc-dhcp-client is a client for DHCP networks.
* cifs-utils provides the SMB/CIFS protocol for cross-platform file-sharing with Unix, Mac OS X, and Windows.
* ftp is command-line file transfer protocol client.
* lftp is an advanced CLI FTP client that supports FTP, HTTP, FISH, SFTP, HTTPS, FTPS, IPv4, and IPv6, works in the background, and resumes interrupted transfers.
* mount displays and manages local and remote filesystems.
* rsync provides fast, efficient remote file copying.
* wget is a reliable HTTP and FTP file retriever.
Network and host discovery and connectivity
* tcpdump is a powerful workhorse packet sniffer for most packet types and protocols.
* mtr-tiny is an ncurses traceroute tool that combines the functionality of the traceroute and ping programs.
* iputils-arping sends ICMP echo requests to an ARP address.
* iputils-ping is the good ol' ping command that tests to see if a network host is reachable.
* iputils-tracepath traces network paths to remote hosts.
* net-tools is a suite of networking commands, including arp, ifconfig, netstat, rarp, nameif, route, plipconfig, slattach, mii-tool, iptunnel, and ipmaddr.
* netcat-openbsd is a versatile tool that reads and writes data across TCP and UDP connections.
* iproute includes commands for networking and traffic control.
* telnet -- wait, really? Yes! It's insecure as it sends traffic in cleartext, but it's still a useful server diagnostic tool.
Hardware tools: Discover, configure, and manage hardware devices
* bluez, bluez-alsa, bluez-cups, and bluex-gstreamer are all Bluetooth utilities.
* hplip includes tools for Hewlett-Packard printers and multifunction printer/scanner/fax devices.
* cups, cups-bsd, cups-client all constitute a printing subsystem with query and test commands.
* ifupdown configures and control network interfaces.
* pciutils detects and identifies PCI bus devices.
* pcmciautils controls PCMCIA devices on laptops.
* parted takes care of disk partitioning and resizing.
* wireless-tools provides essential utilities for managing wireless interfaces.
* rfkill enables and disables wireless devices.
Security: Basic tools for secure network connections
* wpasupplicant is a client for WPA and WPA2 wireless networks.
* iptables provides packet filtering and network address translation.
* openssh-client is a client for connecting to SSH servers.
* openssl provides essential network cryptography and useful commands; one of the most important is s_server, which tests TLS/SSL on mail and other servers, and verifies encryption certificates.
A few miscellaneous (but important!) programs
* coreutils provides essential file, shell, and text commands.
* lsof shows what files have been opened by running processes.
