comment How to make folders 00-99 with a single command in Ubuntu?
@Andrew yes I am aware of that, but I prefer to stay with the coding style of whatever I'm replying to.

You can ditch the loop and just do mkdir $(seq -w 0 99). Or use backticks instead of $(), but I can't put backticks in because of serverfault syntax.

comment Write, wall, who and mesg
What is the difference between wall and a simple loop to do a write to all users one by one? So why block one and not the other?

comment Iptable Rule to redirect all traffic requesting a specific domain
A better solution would be to work with the DNS requests. Either run a DNS proxy and filter the domain out, or do an iptables text match on the DNS queries and reject those packets.

comment (Serving PHP) Does Apache2 will create new thread on every connection?
Creating threads/processes does not equate to 'resource hungry'. With threads they share memory due to being in the same process. With forks (processes) they still share memory due to linux's copy-on-write memory management. In both models, each worker (for each connection) still has to maintain its own data though. Basically dont jump to conclusions. If this model was bad, it wouldnt exist...

comment Intel server hardware failure; does not work
Why not contact intel? There are likely way too many possible causes for this to be answerable.

comment postfix relay access denied from some IPs
This is likely because you are setting mynetworks and sending from one of those networks when at home or on your phone (which I assume is using your home network). You need to set up user authentication so you can send from any network.

comment smartcheck Possible Hard Drive Failure Soon
I have seen such issues caused by things other than the drive itself (such as the controller, or other devices on the same bus). Without seeing exactly what the error is, its hard to tell. You can run smartctl -l error /dev/sda to get more info on what those errors were.

comment CentOS 5/Linux UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
What does /dev/sda/* have to do with /dev/VolGroup00/LogVol00? Also running fsck on multiple devices which arent necessarily filesystems is a really bad idea, especially if youre going to tack -y on to that command.

comment How do I delete everything in the /tmp/ folder?
This is insane overkill. You were asked for additional info which you didnt provide, thus nobody was able to explain why you were having issues.

comment Linux router: ping doesn't route back
@ElBarto I have a sneaking suspicion what it is. Run echo 0 > /proc/sys/net/ipv4/conf/eth1/rp_filter and see if pings work then.

comment Linux router: ping doesn't route back
NAT is already configured. Notice that the packets in both the tcpdump on the router, and the tcpdump on the remote server both show the packets having been SNATed to the new address. The tcpdumps also show the return packets being properly restored.

FORWARD chain has its policy set to ACCEPT, its fine. The tcpdump also shows the packets being properly forwarded (both directions).
