1 Ethereal is a GUI network protocol analyzer.
3 It lets you interactively browse packet data from a live network or from a previously saved capture file.
5 See: http://www.ethereal.com for new versions, documentation, ...
7 Ethereal's native capture file format is libpcap format, which is also the format used by tcpdump and various other tools. So Ethereal can read capture files from:
11 -Shomiti/Finisar Surveyor
13 -Network General/Network Associates DOS-based Sniffer (compressed or uncompressed),
14 -Microsoft Network Monitor
16 -Cinco Networks NetXRay
17 -Network Associates Windows-based Sniffer
18 -AG Group/WildPackets EtherPeek/TokenPeek/AiroPeek
19 -RADCOM's WAN/LAN analyzer
20 -Lucent/Ascend router debug output
22 -the dump output from Toshiba's ISDN routers
23 -the output from i4btrace from the ISDN4BSD project
24 -the output in IPLog format from the Cisco Secure Intrusion Detection System,
25 -pppd logs (pppdump format)
26 -the output from VMS's TCPIPtrace utility
27 -the text output from the DBS Etherwatch VMS utility
28 -traffic capture files from Visual Networks' Visual UpTime
29 -the output from CoSine L2 debug
31 There is no need to tell Ethereal what type of file you are reading; it will determine the file type by itself. Ethereal is also capable of reading any of these file formats if they are compressed using gzip. Ethereal recognizes this directly from the file; the '.gz' extension is not required for this purpose.
