comment List all DNS records in a domain using dig?
@markdrayton, although the scan will send out 2^16 ping requests (~50Mb of raw data, filtered out by most network interfaces), it will only perform reverse-DNS lookups for the hosts that are online.

comment How to access localhost from by ip address?
@Malte Werschy: Sorry, I must have missed your reply until now. I've updated my answer with information about local IPs (192.168.X.X) which should hopefully allow you to bypass whatever security policy is denying you access.

comment Temporarily set ENV variable for just one shell command?
I think the [shell] tag should be more specific ([bourne-shell] I assume).

comment Temporarily set ENV variable for just one shell command?
The [python] tag should only be used when the question directly relates to Python (e.g. it is written in Python). The same idea applies to tags in general.

comment ubuntu - backup mysql directory
@ruigoncalves: You could do a manual backup, but a MySQL-dump would be better.

@Webnet: That seems odd - I'm not sure what to do, try updating the original question with your new problem.

comment RAID 1+0 vs RAID 0+1
A hot spare is a disk that's on standby, and when another disk fails it is activated to replace the failed disk: en.wikipedia.org/wiki/Hot_spare. This would save you if one disk failed, and then the mirrored disk failed before you had time to replace the first failed disk. This is quite an unlikely situation, but not as unlikely as it may appear: en.wikipedia.org/wiki/RAID#Correlated_failures

comment RAID 1+0 vs RAID 0+1
@Webnet: For RAID 1+0 you setup two mirrors first, then stripe them - all of which should be done by the controller, while the OS sees only one disk (as shown in the diagram).
