I'm an old open-source independent hacker,

concerned about concepts of ethical hacking, teaching and sharing.

I like to play with shell, perl, lisp (sometime), sed and lot of other languages/environments.

Co-system administrator in several configurations, after various SMEs, I like to sometimes take time to focus on methods that I can improve or re-create (for example to change the level of abstraction).

In this, surfing on differents StackExchange's sites is a good way to boost my inspiration!

comment How can I replicate this tricky password hashing scheme with ProFTPD authentication?
Bad idea! Don't re-invent the wheel! There is already crypto libs that does this job.

comment Cofiguring DHCP server on ubuntu
There is a lot of conjections in this thread. There is a lot of info missing in the question: What's exact configuration of host ip/mask for interfaces eth1 and even what's others? Question's last report is check syslog for diagnostics, so what's dumped in this f... log!?

It's theorically possible to do: .1 grow physically, .2 grow crypted, than .3 grow fs, or in the other way .1 shrink fs, .2 shrink crypted than .3 shrink partition, but overkill and dangerous as a little error may render your partition unreadable.

comment Preparing for RAID5 failure
Raid 5 is quick and efficient for temporary files or swap (even if hibernation with new linux kernel and proper initrd) but not recommended for storing long term datas.
