Yes, they do. Web browsers are often not good at downloading binary files; they all too often try to "fix" files as if they were text files, by converting line endings - e.g., converting CR/LF to LF if downloading on UNIX, or converting LF to CR/LF if downloading on Windows. > Could u give me any suggestion of how to fixed the download problem. thanks > a lot! > > the web data i will download from is > http://www.ll.mit.edu/IST/ideval/data/1999/1999_data_index.html > The darpa Instrusion detection dataset. Has anyone download this before? Web browsers are especially not good at downloading binary files if some stupid broken or misconfigured Web server is lying and saying the files *aren't* binary files, as the www.ll.mit.edu Web server appears to be doing; when I tried downloading the Monday "inside tcpdump data" file from http://www.ll.mit.edu/IST/ideval/data/1999/training/week1/index.html i.e., the file with the URL http://www.ll.mit.edu/IST/ideval/data/1999/training/week1/monday/inside.tcpdump.gz the Web server put a "Content-Type: text/plain" header into the reply, the fact that a gzipped tcpdump file is not even *close* to being plain text nonwithstanding! If you're downloading this on UNIX, you might try downloading it with the "wget" utility, instead. It may be available as part of your Linux distribution or as a port or package in the FreeBSD port collection. You might have to type in the URL - or use "Copy Link Location" or something such as that and then paste the URL with the middle mouse button - but at least "wget" might just download the raw data and not try to treat it as text. "wget" might be available for Windows as well; I don't know. - This is the TCPDUMP workers list.
