In the other way, with virtualization like openVz you may have many differents hosts after only one mac address.

Not if server use two ethernet cards, for sample on backbones or with backup lines

comment Computing entropy for a passphrase ( minimal word length … )
In fine, I've followed your recommendation to set default random generator to /dev/urandom, but I've added an option to let user ability to choose another way genpassphrase.pl -d wl_15bits.lst -r <(echo -ne '\001\002\003\004\005\006\007\010\011\012').

comment Computing entropy for a passphrase ( minimal word length … )
While I could use this to generate sometime (no more than 10 per a day) one passphrase, with the need of only 10 bytes, is there a good reason to not use /dev/random and to prefer /dev/urandom ??

No, I'm pretty sure in my second sample, using 450bits to humanly choose 5 words would drop entropy down under 75bit in fine. This seem paradoxal, but... There must exist a mathematical demonstration.

This seem UTF8 or UTF16 viewed in Ascii console. There miss some values replaced there by an interrogation point: . Decoding this not possible in this state. we need original raw dumper in hex maybe.

@D3C4FF Yes, of course as there is no external requirement, all this would be better done offline. (In fact the host I use to do this is not configured with a default route)

comment Writing file shredder
Nice exploration of what's about! Just: In order to install a decoy, you have to: .1 shred all blocks, .2 fill all block with 0 (0x00) and finaly .3 install a fake. For ensuring not to leave suspect random data in the last block!
