I installed Apache 2.2 from the Debian repository (6.0/Squeeze). By default, Debian installs the prefork module and comes with the following (default) configuration:

<IfModule mpm_prefork_module>
  StartServers          5
  MinSpareServers       5
  MaxSpareServers      10
  MaxClients          150
  MaxRequestsPerChild   0
</IfModule>

Looking at the scoreboard on the status page, I see there are 256 workers available:

Current Time: Sunday, 05-Jun-2011 22:50:00 CEST
Restart Time: Saturday, 04-Jun-2011 05:49:50 CEST
Parent Server Generation: 3
Server uptime: 1 day 17 hours 9 seconds
Total accesses: 208737 - Total Traffic: 4.6 GB
CPU Usage: u1.08 s.18 cu0 cs0 - .000854% CPU load
1.41 requests/sec - 32.6 kB/second - 23.0 kB/request
1 requests currently being processed, 9 idle workers

I wonder whether it actually is 256, since the list of requests ranges from 0 to 149. Due to a (yet-to-be-discovered) bug, Apache grinds to a halt with 150 active servers, which matches the MaxClients setting. I wonder if the display with 4 rows of 64 characters is misleading and should display 150 characters in total.

Is it possible to extract some details from a file generated with the dump(8) command on a FreeBSD system? Preferably, I'd like to see the file sizes for each file inside, to see what exactly makes my incrementals so large.

I know there's the interactive mode with restore, but the most detail I can get out of it are inode numbers, which I find quite uninteresting.

Or maybe there's a way to mount a dump file as a loopback filesystem, that would be great too.

Is there a way to have a file in the user's FTP home directory without the ability to modify/remove it from that directory over FTP?

So the user has write permissions on his own home folder, thus the ability to remove files. An exception should be made for a single file, which has the same filename and contents for each account.

The solution I'm thinking of right now to run a periodic script to check the presence of that file, and if not, put it back. But I wonder whether there's a better solution than this.
