I have some servers.
I try not to update them.
They are tools, not toys.

The lights are all out.
The servers chanting loud.
Like monks at compline.

comment How do DNS servers interact?
@fahad - that should be a separate question, not a comment to an answer. In the early days, domain registration was run by the department of defense and no fee was charged. Nowadays there is so much administrative overhead in keeping track of millions of domains that people must be employed specifically to do this work.

comment Using NTP to sync a group of linux servers to a common time source
" NTP provides accuracies generally in the range of 0.1 ms with fast LANs and computers and up to a few tens of milliseconds in the intercontinental Internet." cis.udel.edu/~mills/ntp.html

See Eric's answer. I've always used multiple sources.

Your title is "concurrent user" and your content is "concurrent connections" - these are different things - which do you want?

comment Calculate the size of multiple folders accros network
I used to use Perl to recursively sum and display sorted totals. I imagine that this can also be done in any scripting language you are familiar with (VB, Python, ...)

comment Nameserver setup problem - cannot add hostname
It sounds like the hosting company want Godadday to delegate mysite.tw to them. That is delegate the nameservice for the domain mysite.tw. See amended answer

comment Need help trying understanding how to configure DNS
It depends on the protocol to some extent. At the IP-layer, the packet addresses are based only on IP-addresses and Port-numbers, not on DNS hostnames. Your router operates at the IP-layer. Check your router manual but don't hold your breath.

comment Should / Can I use DNS Records to list “Private Hosts in Private LANs”?
(Answer converted to comment to earlier similar answer) You need to configure Split-horizon DNS. When I've done this, it was by having internal computers configured to use an internal DNS server that had zone-files containing the internal names and addresses. These internal DNS servers are configured to refer queries for other domains out to Internet DNS servers. For a large corporation this does mean duplicating the external zone data into the internal zone data. I suspect there are better ways of handling this nowadays (see ref above)

comment File not found problem on VPS vhost environment
I'd use Wireshark (or equivalent) to see what gets sent to the server for the troublesome URL and what, if anything, Apache sends back. Which end closes the TCP connection? I've not encountered a situation where Apache returns nothing and also has no relevant information in (one of) it's errors_log. If that's the case I suggest scrutinising the problematic PHP file and maybe simplifying it drastically to see if you can isolate some PHP code that is triggerring the problem.

No problem, no offence meant on my part. Usually I answer without researching people's posting history to gauge their level of expertise. So sometimes I pitch my answer at the wrong level.

comment File not found problem on VPS vhost environment
You can (as you originally put it) "access a file DIRECTLY" (my emphasis) by using a file: protocol specifier in the URL. You can access the same file INDIRECTLY via a HTTP server on the same computer by using a http: protocol specifier in the URL. If the file is not on the same computer as firefox then using a file: specifier or using the menu File, Open will look in the wrong computer.

comment Virtual hosts pointing to the same directory
I imagine the changes you are making via the shell may be inconsistent with changes that Kloxo has introduced. Since you have a VPS and not shared hosting, I'd ignore Kloxo and reset the httpd.conf to a standard Apache default state and then add the vhosts manually. I'd start by putting the vhost directives in the main file rather than including them. If that worked, maybe move them to separate files - if that's what you prefer.

Is this your own server or a VPS? Are you doing some edits manually and some via Kloxo?

comment Virtual hosts pointing to the same directory
You say "both of the sites show Kloxo Default Page as an error" - is there a numeric error code? Is there a corresponding entry in any of the error logs? I'd check the default log as well as the vhost specific logs.
