Inquiry:problem on unzip a file?

hadimotamedi · 11-28-2009, 11:41 PM

Dear All
I have tried to get a backup from my Red Hat 7.2 server , as the followings :
#tar -czf conf.tgz conf
Then I got a copy from it on my MS Windows client , through sftp .
At now , when I want to unzip it on my Virtual Box Red Hat 7.2 as guest on Windows XP as host it returns as "incomplete literal tree , format violated" . It cannot even be unzipped on my MS Windows client . But it still can be unzipped on the original RedHat 7.2 server, as the followings :
#tar -zxvf conf.tgz
Can you please do me favor and let me know what is wrong in the above scenario that the backup file is no longer useful ?
Let me thank you in advance

I expect you have not installed gzip on your windows machine. I don't use windows but I would be amazed if by default it comes with a tool that can decompress gziped files.

Sorry . But the WinRar is installed on my MS Windows client . Can you please let me know why the file cannot be uncompressed ?
Thank you in advance

Ok, check if it has been corrupted. Check the md5sum

Code:

md5sum conf.tgz

Make sure that the output is the same on both the original Red Hat machine and on the virtual machine.

You should also check on the windows machine, but I don't know how to do that.

From the Command Window prompt: md5sum file.tgz

Edit: sorry, I forgot that md5sum is not a windows command. I installed it from here.

Thank you for your reply . I checked its checksum on my Linux & Windows machine , as the below and attached :
"C:\Documents and Settings\user>md5sum wxc2.tgz
8b4bc0f33bbca8a820bd920239812ee5 *wxc2.tgz"
Please let me know what is wrong here ?
Thank you in advance

Now compare it with the checksum of the original file on the Red Hat server. If they are not the same, something went wrong in the transfer process (and you have to download it again), if they are the same you have to further investigate in order to discover where the problem resides.
