DSM-G600, DNS-3xx and NSA-220 Hack Forum

I remember having also once a weird problem with unrar 3.71 beta 1.
One folder with file inside the rar gave some kind of crc error and was not extracted.
This file was giving no problems with unrar for Windows.

I guess we have to live with it that sometimes you need a Windows box.

Thanks for the ipkg link, after successfully installing it I now find that the 7za binary built for the DNS-323 does NOT support RAR files...

drat drat drat... anyone have a different utility that can deal with RAR files on the DNS-323 ?

I have looked into this as well, trying it with the latest sources available from rarlab at http://www.rarlab.com/rar/unrarsrc-3.9.3.tar.gz
It is actually quite simple to build (just use the provided makefile.unix) to build on your DNS323 use

make -f makefile.unix unrar

to build the unrar binary. Latest sources are 3.90 beta 2.

However, the same problem is there (CRC failed). I found the code that actually determines the CRC_ERROR at the extract.cpp file, line 833 and 834. A check is done on the CRC of the unpacked file and the data IO. I am not sure what actually happens, but in GDB I see that the CRCs are indeed not the same. However, when unpacking the same rar sets on windows using winrar, there is no problem at all....

Now unrar plugin has been added to optware p7zip ipk.
Another difference is libc, DNS323 uses uclibc. Would be interesting to see how unrar/p7zip under chroot debian fares.

I only tested p7zip on other optware feeds. Since I don't have DNS323, I'd rely on other people to test and report.

Anybody some more luck investigating this problem?

I have downloaded terrabytes with nzbget already and before that i was  having severe issues with finding and using the correct unrar

ULI has made a package for unrar and I am using it for my nzbget installation I created for those who has not a lot of scripting skills
find here the unrar I am really happy about http://www.aroundmyroom.com/ch3snas-fun … .7.8-1.tgz

and to be honest, not all files will be 100% unpacked correctly, sometimes i see that the RAR files do have a CRC error, than it's (for nzbget) just not unpacked available in the Download folder.
but 99% of all my usenet files are unpacked without issue, but than with this version of unrar cause others do crash or have strange behaviour.

Hi There,

I have installed the same package than zeroday above but none of my rared files are decompressed after the download.
The sfv check and repair are working fine though.

Try setting the permissions to 777.

Hi guys,

any chance somebody has another idea ?

Thank You !

Thanks for your feedback StealthOne, I will try to replace the unrar version I have with the one you gave however I believe it is more a script issue.
I have tweaked my scripts and fixed the problem posted above but I have now this persistent error each time the download has been done, checked and repaired :

Apparently, it creates a temporary config file to operate as it can't find the settings but they are well populated that s why I do not understand.
The new temporary config file is based on the .config.example in the folder when you read the full unpak script.
maybe somebody has an idea to fix this...
