I have tested it before but i have two problems: it is true that ethereal reads a number of file formats, including the file formats of AiroPeek but i can't save it as libpcap format (when i click in save as i only can save as AiroPeek trace (V9 file format). I have also tested using editcap but an error message appear: i put in the command line this: C:\>editcap inputfile.apc outputfile.dmp editcap: Can't open or create outputfile.dmp: Files from that network type can't be saved in that format The same message appear if i put: C:\>editcap -F libpcap inputfile.apc outputfile.dmp
That's one problem, not two - the underlying problem is that we don't support writing out that particular style of 802.11+radio information in a libpcap capture.
I've checked in a change to do that, for now, by discarding the radio information. At some point we'll choose one of the many different 802.11+radio header formats in libpcap and use that. (My favorite is the BSD radiotap format, but I need to get that working in tcpdump first - patches exist, but they depend on 64-bit integer support, including printing 64-bit integers, and "%ll[dox]" does *NOT* work on all platforms supported by tcpdump, *OR* all platforms supported by Ethereal, for that matter - and should get libpcap able to handle at least that flavor of variable-length link-layer header, which I think might be a bit easier than Token Ring or full support for 4-MAC-address 802.11 as it doesn't involve conditional branches.)
