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 RAID 1E with ZFS
Yes! With 27 physical disk, you may build 9 raid 1E using HW-Raid controlers, than you could build 3 Linux MD Raid-1e, useable as 3 physical devices for ZFS, from where you may use copies=2 to be able to use 1.5x size of 1 disk... data would be redundants!

comment Possible to build a RAID 1 with only one drive with LSI 9260-4i?
Under Linux MD, you could build a degraded array than repair them lather: mdadm --create md0 --level=1 --raid-devices=2 /dev/sda1 "missing". But I agree with @Adrian, this has nothing to do there...

comment LVM, Soft RAID1, and Replication?
Remember: the more are technologies involved, the more chance is to see bug or failure in one of each stacked system... border effect and other funny/interesting things! Keep your backups up to date!!!

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!?

comment Secure a live server
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.
