Failed to extract download in 7 Zip

Submitted by Helen Gao on Mon, 05/02/2011 - 16:52

I just downloaded owasp-wte-Feb-2011.iso.rar. When I tried to extract it using Windows 7 Zip, I got an error message: "Data error in owasp-wte-Feb-2011.iso. File is broken." Your advice will be most appreciated.

Hi all, I downloaded the WTE

Hi all,

I downloaded the WTE a few times by now. I always get the same error when trying to decompress it. I tried 7zip, winrar and a couple of other tools.

It seems that the file is "broken" or something.

Also, the download speed is very slow (~20KS/s).

Is there any mirror or other site that I can use for the download?

I am currently located in Greece.

Thank you all.

Failed to extract download in 7 Zip

Helen,

The first thing I would check is the MD5 sum of the .rar file to make sure your download wasn't corrupt/bad. I just checked both a downloaded version and the original and I get the same value:
$ md5sum owasp-wte-Feb-2011.iso.rar
9bdc6a6d3cecba44e0165387ec2a8d18 owasp-wte-Feb-2011.iso.rar

I used Linux tools to create those rar files so perhaps there's an implementation difference between Linux's rar command and 7 Zip. I did successfully unrar the file with IZArc under Windows which you can get here:
http://www.izarc.org/

Finally, I should note under full disclosure that there are some known bugs in the .iso image. If you are going to be launching that .iso in a virtual machine, I'd suggest you get the VirtualBox .vdi file or the VMware .vmdk. The .iso bugs are not present in those versions.

HTH
