There are some other ".CAP" file types. One site listed these: Network Associates Sniffer Capture File Agilent LAN Analyzer Capture File Fluke Protocol Inspector Capture File Microsoft NetMon Capture File Shomiti Surveyor Capture File Sun Snoop Capture File TTC FireBerd 500 PC Capture File WWG Domino Capture File WWG LinkView PRO Capture File Fluke Optiview cap-format (same as Finisar Surveyor ????) might be based on the snoop format: http://www.ethereal.com/lists/ethereal-users/200208/msg00149.html http://techupdate.zdnet.com/eweek/stories/pipreviews/0,11535,436131,00.html http://www.thetechfirm.com/fluke_ope/ However it seems that maybe it is possible to convert to NAI Sniffer enc-format (and Internet Advisor format) directly from the Optiview. The enc-format files might work better with Ethereal. Regards, Martin
