comment 100% uptime for a web application
I beg to differ. "Not useful at all?" It was most certainly useful for me and contrary to your "hire someone else to do it" comment, I suppose with your reasoning the guy should trench his own fiber optic cable and design his own switches rather than buy them too? Are you serious, Yves? You sound like someone who has not spent much time in the IT field.

comment Using NTP to sync a group of linux servers to a common time source
@MattBianco: No. We use a custom script for that. It is an implementation detail specific to the environment. To shed some light on this, the script runs on our masters and requests the time from each client node out there. It knows of the clients as all our hosts use central LDAP. This script is part of many we run as a daily "morning report" we call it. Variables in the script allow us to set thresh holds which we report out through a nagios dashboard.

comment Is it normal to get hundreds of break-in attempts per day?
while I agree with others this is normal on common ports required (80, 443) I practically eliminated these attempts against my SSH port by simply changing the default port from 22 to something obscure like 6022 for example. Just doing that, alone, nearly eliminated 99% of that type of attack.

comment Best VoIP VPS Location?
QoS does you no good against in-bound traffic, keep in mind. It's good to have but it's not a complete solution by itself. The answer, however, to #1 should be obvious. Lower latency is always better.

comment Apache RewriteRule with a RewriteMap variable substitution for the VAL argument to environment variable
I solved it. I overlooked the fact that the md5digesthex.pl had to be a long running app. So I change the perl code run inside a while(<STDIN>) loop instead and I now get the desired results... Thanks for the help.

comment Apache RewriteRule with a RewriteMap variable substitution for the VAL argument to environment variable
Yes, wish I was around to slap the original developers. Anyway, the output of the md5inhex is just a hex string. I pass it the name of a file, it computes the MD5 and returns the hex value i.e. 0xBADBEEF.... I've tested it on the command line and it works and a browser test prompts me to download the file but HTTP header never gets set.

comment Apache RewriteRule with a RewriteMap variable substitution for the VAL argument to environment variable
very true. I guess I need to explain why I need to solve this? OK, it's a very large system. Some 4 or 5 back end systems that all use the same MD5 in hex format and the client is at some 30,000 locations. When you have a very large system such as this, you simply can not change the client and be done. This is a tactical approach until a more strategic architecture can be developed. We currently serve up binaries from a database application and the load is growing too high hence the reason to move to a web server.
