- Ethereal for Windows
- Ethereal for Unix
Ethereal is a GTK+-based network protocol analyzer, or sniffer, that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and to give Ethereal features that are missing from closed-source sniffers. Changes: Many protocol decoders updated (RTP, IP, ISAKMP, ICMP, SMB, SMB-PIPE, VTP, SNMPv3, Ethernet, GRE, EIGRP, DHCP, IPX, X.25, RSVP, and L2TP) new decoders for Mobile IP and COPS. A new API for the dissectors has been implemented which catches more compile time errors. Also added the ability to read compressed sniffer files and many small tweaks and bugfixes.

Analyzer v2.02 is a full configurable windows packet sniffer and network analyzer. Developed in a Win32 environment, it works on both Windows 95/98 and Windows NT/2000 platforms. It features a GUI, an analysis engine and a capture program. Changes: Packet Capture performance greatly improved, support for Windows 2000 added, and many bugs fixed. Requires a packet driver, available here. Homepage here. By Piero Viano
- Sniffit for UNIX
Sniffit 0.3.7beta - Very good packet sniffer for unix. Has an interactive mode where you can select connections in progress to watch, or a mode to log packets to a file in the background. Supports a configuration file and tpcdump like packet filtering. Sniffit runs on LINUX, SunOS, Solaris, FreeBSD and IRIX. Homepage here.
- Sniffit for Windows NT/2000
Sniffit 0.3.7 beta for Windows NT/2000. This package requires winpcap, available here. Homepage here. By Symbolic Worldwide
dsniff is a suite of utilities that are useful for penetration testing. It consists of the following programs: arpredirect intercepts packets from a target host on the LAN intended for another host on the LAN by forging ARP replies. findgw determines the local gateway of an unknown network via passive sniffing. macof floods the local network with random MAC addresses. tcpkill kills specified in-progress TCP connections. dsniff is a powerful sniffer which automatically detects and parses many protocols, only saving the interesting bits. filesnarf saves files sniffed from network file system traffic. mailsnarf outputs all messages sniffed from SMTP traffic in Berkeley mbox format. webspy sends URLs sniffed from a client to your local Netscape browser for display, updated in real-time. Changes: New programs: dnsspoof, msgsnarf, sshmitm, webmitm. Dnsspoof forges DNS queries and answers, msgsnarf records selected messages from sniffed AOL Instant Messenger, ICQ 2000, IRC, and Yahoo! Messenger chat sessions, sshmitm monkey-in-the-middle. proxies and sniffs SSH traffic redirected by dnsspoof(8), capturing SSH password logins, and optionally hijacking interactive sessions. webmitm transparently proxies and sniffs web traffic redirected by dnsspoof(8), capturing most "secure" SSL-encrypted webmail logins and form submissions. Also added VRRP, pcAnywhere 7, 9.x, SMTP, rexec, RPC ypserv, NNTPv2, Checkpoint Firewall-1 Session Authentication Agent, and Microsoft PPTP MS-CHAP (v1, v2) parsing to dsniff.

Ngrep is a powerful network sniffing tool which strives to provide most of GNU grep's common features, applying them to all network traffic. ngrep is a pcap-aware tool that will allow you to specify extended regular expressions to match against data payloads of packets. It currently recognizes TCP, UDP and ICMP across Ethernet, PPP, SLIP, FDDI, and null interfaces, and understands bpf filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop. Changes: Updating the display when window sizes change in standard match mode, new configure options to compile with the pcre library (which is more license-friendly, albeit slower) and --without restart (remove the pcap restart API call), and bug fixes.
