Set up a wireless server, allowing access to files on computer, without offering internet
Pretty much all you need to do is to set up a router somehow - I
do believe some wireless adaptors would do that, and/or you can
use hostapd. Tricky thing really is to get the users
to find the server - you would need to set up a captive portal for that - the firewall approach
makes most sense here. If you wanted to make it even simpler,
just name the AP in some way its obvious how to find the server
;)
Something that might work perfectly, with a few tweaks is the
piratebox - these installations scripts would be what you're looking
for, and there's more usecases here.

Linux server broken packages
Ok here's what I ended up doing:
First of all, I would recommend using aptitude
instead of apt-get because it makes better choices
by default. So, I went ahead and accepted aptitude's first
solution, which was to leave everything the same version except
for php5-curl which was to be installed. Trust me,
you don't want to update the php5-common or
libapache2-mod-php5 packages on a mission-critical
server because they have a million dependencies. Then the server
couldn't download the package because the repositories are
outdated on this server (it's 10.04 remember) and it couldn't
find the .deb file. So, I copied the name
php5-curl-5.2.10.dfsg.1-2ubuntu6_amd_64.deb and
Google'd it and found site hosting the .deb file. I then did the
following commands to install this package without causing
dependency hell:
$ wget http://www.thesitewhereyoufounditongoogle.com/php5-curl-5.2.10.dfsg.1-2ubuntu6_amd_64.deb
$ sudo dpkg -i php5-curl-5.2.10.dfsg.1-2ubuntu6_amd_64.deb
and then of course restart Apache
$ sudo /etc/init.d/apache2 restart
And voila! cURL was installed.

See active connection on apache web server

I think for seeing current ip connectivity only this is the
command there . You can refer this for advacned usage
http://www.thegeekstuff.com/2010/03/netstat-command-examples/

It shows all type of connections time_out , Time_wait , and
connected and established in state .
For the above commands, you can do google

View specific virtualhost from within Virtualbox Windows XP?
I have the same setup as you do (Debian host, VirtualBox, WinXP
guest {plus a Win2k3 server guest}), and IP-based routing works
fine without using ports.
Although I did create a hosts file entry in each VM that points
to 192.168.56.1, there is no "harm" in doing that since the IP
will never change.

Creating a separate access_log and error_log for Apache2
An .htaccess file won't work, sorry. You need to put it in a
logfile.
From the config docs at apache
CustomLog Directive
Description: Sets filename and format of log file
Syntax: CustomLog file|pipe format|nickname [env=[!]environment-variable]
Context: server config, virtual host
Status: Base
Module: mod_log_config
I haven't tested to see if it works in blocks though. You might
want to experiment with that. Failing that, they have an example
of SetEnfIf and CustomLog based on env vars
which would work for what you wanted.

Apache can't bind to address [::]:80, already in use
Chrome is not listening on a local port 80 but just
connected to a remote port 80.
I don't really see a problem. But try to specify an IP to listen
on, as it seems to be failing on IPv6 right now...

httpd running but Apache not listening
This turned out to be a firewall issue. The IP address for dev
was not opened in the firewall.

How do I save log files to another partition?
You can configure the location of the log files in
apache2 in /etc/httpd/conf/httpd.conf:
ErrorLog "/var/log/httpd/error_log"
<IfModule log_config_module>
CustomLog "/var/log/httpd/access_log" common
</IfModule>
If you feel like too much information is being logged by apache,
you can change the log level in
/etc/httpd/conf/httpd.conf to warn,
crit or alert (please see the apache documentation page for more information
on loglevel values):
LogLevel warn
If that's not enough, you can also modify the
logrotate config for apache2 in
/etc/logrotate.d/httpd. The logrotate for
apache2 is usually configured as a daily cron job.

How to make SSHFS case sensitive
The problem is not SSHFS but the file system on OS X. HFS is case
per default case-insensitve. HFS remembers the case of a name but
the file system is case insensitive.
It is now possible to format an OS X partition with HFS Plus with
the "case sensitive" option, but Apple is still prudent and
cannot guarantee that applications will not have problems.

How do I prevent Apache service from auto-starting on Linux?
Depending on your distro, you should be able to execute a command
to disable the service on startup. Doing this it will be stopped
until you manually start it. Here are some examples on different
distros:
- Ubuntu/Debian:
update-rc.d -f apache2 remove
- Gentoo:
rc-update del apache2
- ArchLinux:
systemctl disable apache2

Apache2 + mod_fcgid + php stopped working after upgrade from Debian squeeze to wheezy
Now I stumbled upon the solution by myself. The problem is caused
by an update of mod_fcgid which changed the directives used in
the vhost configs. The changes could be seen here (this is what I stumbled upon).
The directive
FCGIWrapper /var/www/example.com/php-fcgi/php-fcgi-starter .php
has to be changed to
FcgidWrapper /var/www/example.com/php-fcgi/php-fcgi-starter .php
The documentation says
"All directives have been renamed in order to use a common
prefix "Fcgid". Underscores in directive names have been
eliminated in favor of CamelCase. The old directive names will
still work but are deprecated. To fix your configuration you
can use the sed script build/fixconf.sed."
but it seems like the old directive names didn't work anymore for
now. The changes have done the trick for me, maybe this will help
someone else.

Apache2 mod_mono ubuntu virtual hosting
You can check the apache log file and see what the error is and
search for solution on it.
/var/log/apache2/error.log
In my case, I have installed mono and mod_mono from source. They
work on apache with PHP working on it. Here is a link that will
help you get started:

Setting local network via WiFi
1) Introduce, in your DHCP server config file (located
differently on different distros, in Debian and derivatives it is
/etc/default/dhcp3-server, for other distros you will have to
hunt it don), the following line:
option domain-name "your-domain.org";
inside the subnet stanza.
2) use the following iptables rules:
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
iptables -I INPUT 2 -p tcp --dport ! 80 -j DROP
iptables -I INPUT 3 -p udp -j DROP
options
-d
serverroot
Set the initial value for the
ServerRoot directive to serverroot. This can be
overridden by the ServerRoot directive in the configuration
file.
-f config
Uses the directives in the file
config on startup. If config does not begin
with a /, then it is taken to be a path relative to the
ServerRoot. The default is /etc/apache2/apache2.conf.
-k
start|restart|graceful|stop|graceful-stop
Signals apache2 to start,
restart, or stop. See Stopping Apache for more
information.
-C directive
Process the configuration
directive before reading config files.
-c directive
Process the configuration
directive after reading config files.
-D parameter
Sets a configuration
parameter which can be used with <IfDefine>
sections in the configuration files to conditionally skip or
process commands at server startup and restart.
-e level
Sets the LogLevel to
level during server startup. This is useful for
temporarily increasing the verbosity of the error messages
to find problems during startup.
-E file
Send error messages during
server startup to file.
-R directory
When the server is compiled
using the SHARED_CORE rule, this specifies the
directory for the shared object files.
-h
Output a short summary of available command line
options.
-l
Output a list of modules compiled into the server. This
will not list dynamically loaded modules included
using the LoadModule directive.
-L
Output a list of directives together with expected
arguments and places where the directive is valid.
-M
Dump a list of loaded Static and Shared Modules.
-S
Show the settings as parsed from the config file
(currently only shows the virtualhost settings).
-t
Run syntax tests for configuration files only. The
program immediately exits after these syntax parsing tests
with either a return code of 0 (Syntax OK) or return code
not equal to 0 (Syntax Error). If -D
DUMP_VHOSTS is also set, details of the
virtual host configuration will be printed. If -D
DUMP_MODULES is set, all loaded modules will
be printed.
-v
Print the version of apache2, and then exit.
-V
Print the version and build parameters of apache2, and
then exit.
-X
Run apache2 in debug mode. Only one worker will be
started and the server will not detach from the console.
documentation
The full documentation is available in the apache2-doc package or
at http://httpd.apache.org/docs/2.2/ . Information about Debian
specific changes and configuration can be found in
/usr/share/doc/apache2.2-common/README.Debian.gz .
summary
apache2 is the Apache HyperText Transfer Protocol (HTTP) server
program. It is designed to be run as a standalone daemon process.
When used like this it will create a pool of child processes or
threads to handle requests.
In general, apache2 should not be invoked directly, but rather
should be invoked via /etc/init.d/apache2 or apache2ctl. The
default Debian configuration requires environment variables that
are defined in /etc/apache2/envvars and are not available if
apache2 is started directly. However, apache2ctl can be used to
pass arbitrary arguments to apache2.
