A Guided Tour of Ethereal
For more information on Ethereal, start with www.ethereal.com. This page includes links to the Ethereal manual, downloads and mailing lists.
To understand better what Ethereal is showing you, you need the appropriate documentation on the network protocol. Those protocols, codified by the Internet Engineering Task Force, are available at www.rfc-editor.org.
rsync is an efficient network file transfer application originally developed by Andrew Tridgell (of Samba fame). See rsync.samba.org.
zcip is a tool for automatic assignment (zeroconf) of IPv4 addresses, without needing a DHCP server. See zeroconf.sourceforge.net.
Service Location Protocol is a way for clients to find servers in a network-efficient way. See www.srvloc.org for more details on the protocol, or refer to RFC 2608, RFC 2609, RFC 2610 and RFC 2614, available from www.rfc-editor.org. A free implementation, mainly developed by Matt Peterson, is available at www.openslp.org.
The capturing capabilities of Ethereal depend on libpcap, developed by the TCPDUMP Group. You need libpcap to build Ethereal, although most distributions ship with libpcap packages. See www.tcpdump.org.
The Windows version of libpcap is WinPcap. See winpcap.polito.it for more information and to download the installer package.
IMAP (Internet Message Access Protocol) is a server-based e-mail protocol, in many ways superior to the Post Office Protocol (POP) that is widely used. For more details, get RFC 2060 from www.rfc-editor.org.
distcc is a distributed compilation application developed by Martin Pool that uses various network machines to participate in building C code. See distcc.samba.org.
