Hi, anyone want to help Oliver? His ftp search site: www.filewatcher.org keeps track of 450 million ftp-able files including lots of Linux stuff. I have a 771,000+ ftp archive that his scanner hickups on so he is going to re-write it.....<br><br>Tom Miller<br><br><b><i>Oliver Maruhn <oliver@maruhn.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Subject: RE: Yet another ftp site: ftp://ftp.chatnfiles.com<br>Date: Wed, 17 May 2006 16:12:15 -0400<br>From: "Oliver Maruhn" <oliver@maruhn.com><br>To: "Tom Miller" <tlgalenson@yahoo.com><br><br> Hi Tom, <br><br>> Thank you for the reply. I have a suspicion that one of the <br>> issues you will have to address are longer file paths. It <br>> seems to me Unix/Linux etc has a much shorter file-path <br>> length limit than Windows. <br><br>FileWatcher has its own Datababase which supports Filenames/Path up to
a<br>length of 255 characters. I guess there is some string buffer overflow<br>in our current scanner which prevents scanning your site correctly.<br><br>> I know the webmaster specifically <br>> took advantage of the long-path-names to help identify the <br>> downloads. And he does use/allow blanks in the file paths.... <br><br>That is good practise and fully supported by FileWatcher.<br> <br>> Oh, yes, what language is the scanner written in? <br><br>The current scanner is written in C. That was necessary because we scan<br>many ftp sites simultaniously and therefore needed a program which had a<br>small memory/load footprint. The current scanner is very fast an needs<br>very few resources. But the problem is that C is not very good in<br>string handling and that it is next to impossible to debug the code for<br>buffer overflows.<br><br>Today servers have much more power so we decided to rewrite our scanner<br>in PERL. The new scanner will need much
more CPU time and RAM since<br>PERL is a pseudo-interpreted language. On the other side PERL offers<br>very good string manipulations and buffer overflows are unknown to this<br>language.<br><br>> Maybe I can find some free help to do your coding.... :) <br><br>Thanks for you offer. If one really wants to help rewriting the scanner<br>from scratch he must have very good knowledge about PERL, unix sockets,<br>and of course the ftp protocol. Also he should understand some C to<br>read the source of the current scanner.<br><br></blockquote><br><BR><BR><div id="RTEContent"><div>---------<br>Do you need computer help?
