Repeated checksum failure -- how to find the cause
 
I have repeatedly downloaded a mageia iso and always get a checksum failure. I tried it to two different hard drives and it always fails. It also fails with download as a torrent. Both drives check OK with gsmart.

I downloaded it onto my Mac using a physically different network and it was OK, but when I transferred it via my home network from my mac to may Linux box the checksum failed again.

I am using Mandriva 2011, have two HDD's and both seem OK. I have a network at home behind a router and have disabled the firewall on the Linux box, but not on the router.

I don't know where to look or what are the next steps to resolve this problem of file corruption. Any suggestions would be gratefully appreciated.

Am using Mandriva 2011, Firefox 15.0, Ktorrent 4.1.1, and have tried different mirrors for the Mageia download. The Ktorrent download never ends because it always has some chunk failures and keeps trying to correct them.

Thanks in advance.

How are you transferring the file and how are verifying the checksum?

I am doing a sha1sum.
sha1sum /path/to/file

I transferred it via torrent as well as a direct download.

I just turned off my router's firewall and downloaded the file to a new partition on the HDD and the checksum is OK!

That seems to have solved the issue, though I don't understand. Before this I had tried to download it about 8 times with a checksum failure everytime. This is the first time I turned off the router firewall.

Thanks for offering to help.

Nice that you found a solution to your problem. If you want to mark a thread as solved please don't manually change the thread title, but use the thread tools at the top of the thread. This way your thread will be recognized by the search function of the forum as resolved, which is not the case if you just change the title.

Thank you. I did not realize that.

Please post what router firewall you are using. This could be useful to others.

FWIW, I have a WRT300N Linksys, Firmware 0.93.0, and just went to <Security->Firewall> and then just Disabled the SPI Firewall Protection.

I hope this is what you were looking for.
