I donwloaded the source from the FTP server (ftp.dlink.com/GPL/DNS-343/); unfortunately, the file is corrupted. The following error has been replicated on FreeBSD, Ubuntu and Mac OS X, all independently downloading the source (using wget, wget and Cyberduck, respectively)
$~/Sources$ tar -zxvf dns343_GPL_v1.03_08142009.tgz
dns343_GPL/
dns343_GPL/Readme.TXT
dns343_GPL/D-Link GPL Written Offer.HTML
dns343_GPL/firmware_description.HTML
dns343_GPL/GPL_License
dns343_GPL/dns343_GPL.tgz
gzip: stdin: invalid compressed data--crc error
tar: Child returned status 1
I'd really like to play around with it, but the above is sort of a hindrance.
