comment how does ntfs implement raid 0
A file system filter driver filters filesystem requests (like 'open file', 'remove directory', and so on). The RAID is implemented more like a block device filter, handling the requests issued by the filesystem (like 'read block', 'write block'). When the filesystem goes to write a block, a mirroring RAID driver will write the block to both drives. When the filesystem goes to read a block, the mirroring RAID driver will try to read the block from one drive and if it fails, the other. There are a few reasons you can't do it the other way. (How would 'chkdsk' work?)

comment apache-memory-hacker-linux
"Once it take the memory it is nuable to rlease the memory." It's not that it's unable, it's that there's no point. Free memory does no good, it might as well not be there. Only memory that is in use helps performance. If you want free memory, take it out of the computer and put it on your desk. If you put it in the computer, the computer will use it. The more memory the computer uses, the faster it runs. That's why you put more memory in a computer.

Software RAID is usually implemented by a block driver below the filesystem, not a filter driver above it.

comment Forward my http requests from my ip to another server
I think you probably forwarded the packets rather than the connections (through NAT). Forwarding the connections should work.

comment thttpd: Daemon exiting, I don't know why
I think arjarj nailed it. There's probably something like a logrotate script that sends a fatal signal or the like.

comment Does forwarding Email leak the destination address to the public?
You can test by forwarding to a non-existent address and then sending an email. Look very closely at the headers in the error reply you get.

comment NAT UDP Hole punching beginner's basic Qn
@abhinav: Your router will only send a packet to your ISP if the ISP's side of the link is its final destination or if it doesn't have a more specific route to that destination. Neither condition applies here -- your router has a more specific route to its own interface, the interface route.

Yes. Then it would know which interface to associate each packet with by VLAN.

comment multiple wildcard entries
I don't quite follow. You mean like "ww1.foo.mydomain.com" and "ww1.bar.mydomain.com" and so on should point to 24.24.24.24?

comment Setting http://domain and http://ip to show different directories
You would be relying on the server to use DNS to find the IP. If that failed for some reason, the server couldn't configure itself.

comment Setting http://domain and http://ip to show different directories
If you do that, and anything is wrong with DNS when Apache starts up, Apache will misconfigure itself.
