...although I put the filter into a file on UNIX, so there were only LFs at the ends of lines, not CR/LFs.
Exactly. scanner.l doesn't understand '\'r' in line-endings. I tried to modify scanner.l to say "[ \r\n\t] ;" instead of "[ \n\t] ;", but that didn't work. So I modified read_infile() to strip all CR and LF from buffer and now it works. PS. There should IMHO be a more detailed error when parser fails. A line + column position perhaps? I'm no flex expert, but might contribute a patch.
If I create the file with Notepad (good old Microsoft - they let me do notepad e:\filterfile.txt from the command line!), and then try .\windump -r {capture file} -dF e:\filterfile.txt I get .\windump: short read e:\filterpoop.txt (156 != 162)
Something to do with _fmode or fstat() returning wrong size for DOS/Win files perhaps. IMHO, would be better to use filelength() under Win32. Gisle V. - This is the TCPDUMP workers list.
