comment How do I make sure I have dedicated SSL for my site on a shared server?
It could, but it could also mean the web server needs the site name as well as the IP address to find your site.

comment IP segmentation occouring at irregular boundaries
I just noticed that the title of your question doesn't seem to relate to the body of your question at all. What does the body of your question have to do with "irregular boundaries"?

comment Hotmail wants me to modify my SPF record
The exact answer will depend on why the ptr is in there. If it was added for no particular reason, it can just be removed. It was added for a particular reason, some other way to do whatever made it required will be needed.

comment IP segmentation occouring at irregular boundaries
Well, one thing that's definitely off is that the MTU has to include the IP header as well as the data. Each packet has an IP header that cuts into how much data it can carry.

comment Apache on linux with two real certificates (.com and .co.uk)
What are you trying to accomplish? What problem is this the solution to? (Also, this won't work if both services are using the same IP address. SNI is not production-ready yet.)

comment swap partition alignment: is there any benefit?
The system may dribble swap out under normal load a bit. But the system shouldn't swap enough for swap performance to make any difference at all. But there is a myth that literally no swapping should occur under normal load, and that's false for precisely the reason womble mentioned.

comment How can I find out what user from a specified IP is doing with my server?
You should always keep logs like this, and make sure to also keep a timestamp of when the log was created that is as exact as possible (with the time zone).

comment Apache rewrites custom reason phrases in HTTP header to a standard one
Check the logs for your customer's server. It's most likely not ignoring the additional message but in fact encountering an internal server error.

comment D-Link override DNS for all computers on network?
Unfortunately, there is no open source software for it because it uses the Ubicom IP5160. You're stuck with the factory firmware.

What protocol? You only told us what it's not. That's not helpful.

The system does not assume that everyone using it is in the same time zone the system is in.

comment Software RAID setup questions
@jdickson: If you are worried about losing your data, you need to back it up. RAID is about minimizing and avoiding down time, not protecting against data loss.

It is marked as spam by who or what? You forgot to tell us what this problem is about.

comment Different results from GnuPG and OpenSSL when using AES256 encryption
Both of these tools internally use AES256, but their output formats are completely different. Can you be more specific about what you're trying to do? Do you really need deterministic encryption where the same input always produces the same output?

comment Why does RAID5 with an odd number of data disks have poor write performance
@psusi: You're taking us in circles. Right, we all agree on that. Again, the question is: After this aggregation, do you think more writes will be an even multiple of 2MB or more writes will be an even multiple of 2.5MB?

comment Why does RAID5 with an odd number of data disks have poor write performance
@psusi: I don't understand why you keep taking us in circles. Yes, there's aggregation. But after aggregation, if the write is an even multiple of the stripe size, no read before write is needed. Otherwise, a read is needed before the write. Do you think more writes will be even multiples of 2MB or will be even multiple of 2.5MB? If more writes are even multiples of 2MB than 2.5MB, then a RAID with a stripe size of 2MB will perform better since less data will need to be read in order to write.
