Unpack target archive as instructed by the README: $ tar jxvf 2 So, no libraries, programs or kernel recompiling involved. In fact, we won’t need to recompile anything, as the target overlay we’ll be enough for us to neutralize scfgmgr. View the official README procedure for rebuilding custom firmware: $ cat README Grab the firmware’s source code from Netgear’s site &. blah blah blah …Insert here the usual disclaimers… blah blah blah. I’m not liable for any damage to your computer system or loss of data. WARNING: Use these directives at your own risk. So, here is a try at rebuilding a firmware (version 2.00.27_WW) with a neutralized /usr/sbin/scfgmgr. However, perhaps we can simply neutralize it (in the target overlay) hoping that there won’t be any wrong side effects with the overall working of the firmware? Looking in the DM111P firmware, you’ll find that the despicable scfgmgr is bundled as a binary in 2, so it cannot be edited and recompiled to get rid of it’s infamous behaviour. Perhaps we could recompile a firmware with a « fixed » version of scfgmgr? Looking for a way to close this « back » door, I noticed that most of Netgear’s firmwares source codes are available from their site.
Lately you found that your DSL modem/router was wide open, and you want to fix it.
