Solving some NFS issues on Hikvision cameras

I got this off comments people posted on my blog at NetworkCameraCritic.com, so hope it helps a wider audience. Thanks to s400py and peter. This is not for the novice, but hopefully after a few people do it they can comment on their experience. OK, here’s the bug: When you “format” the hard drive, a file “info.bin” is generated in the root of the directory. It contains the number of “datadirs” at the very end, i.e. available space in the network share divided by maximum size of a single datadir. When the firmware tries to reconnect to the NFS share, it assumes that the full drive capacity (not the free space) reported by the NFS server can be fully utilized. The file “info.bin” only contains the number associated with the free available space (<= HDD capacity) so it fails. I've patched out that check in /dav/davinci so everything's working now. 5.0.2 Version telnet into the device, copy /dav/davinci to your network share (‘mount’ tells you the directory). open the file with a hex editor, search this hexadecimal string: 5001D4C09DE52C00001A07005CE12A00001A replace with: 5001D4C09DE50000000007005CE100000000 save. copy the file from the network share back to /dav, reboot the device. 5.1 Version search for the following hex string: 5001DCC09DE54900001A0B005CE14700001A and change it to 5001DCC09DE5000000000B005CE100000000
