| Monitor users via VNC |

Hi,
I have been wondering if anyone knows how to monitor users on the network via vnc
so you can login into there screen and watch what they are doing?
I looked at kdenetwork3-vnc which I was able to login on a users session and watch what they
were doing, I was also able to type and control there mouse. It would be better if I could of
disabled them using the mouse and keyboard.

| install mmcache for php |

Maybe you have heard about Turck MMCache, basically it caches php code into memory to help speed up dynamic content based sites. Its a great little php addon for forums and heavily used sites. This will go through how to install mmcache for your rpm based installs for apache/php on fedora/redhat systems.
First lets download mmcache from sourceforge
Code: wget http://superb-west.dl.sourceforge.net/sourceforge/turck-mmcache/turck-mmcache-2.4.6.tar.gz
Now lets extract it and go into the mmcache source directory
Code: tar zxfv turck-mmcache-2.4.6.tar.gz
cd turck-mmcache-2.4.6
Now we need to set a var. If you are using the standard rpms it will be in /usr so lets set that.
Code: export PHP_PREFIX="/usr"
Now lets compile mmcache
Code: $PHP_PREFIX/bin/phpize
./configure --enable-mmcache=shared --with-php-config=$PHP_PREFIX/bin/php-config
make
make install
Now lets copy over the compiled mmcache module into the same place where the php module is installed for apache. This is just to keep it neater. You are free to put it anywhere you want. Just make sure you make the same changes below when we edit the php.ini file
Code: cp modules/mmcache.so /usr/lib/httpd/modules/
Now lets edit the php.ini file. It is in /etc/php.ini in the rpm installs. We want to add the following lines at the bottom of the file
Code: zend_extension="/usr/lib/httpd/modules/mmcache.so"
mmcache.shm_size="16"
mmcache.cache_dir="/tmp/mmcache"
mmcache.enable="1"
mmcache.optimizer="1"
mmcache.check_mtime="1"
mmcache.debug="0"
mmcache.filter=""
mmcache.shm_max="0"
mmcache.shm_ttl="0"
mmcache.shm_prune_period="0"
mmcache.shm_only="0"
mmcache.compress="1"
Now lets make the temp directory for mmcache and then chmod it correctly
Code: mkdir /tmp/mmcache
chmod 777 /tmp/mmcache
Now lets restart apache
Code: service httpd restart
Now just load up a php page on your website and you should see files in the /tmp/mmcache directory. If you don't then change the zend_extension part to extension in your php.ini and then restart apache again.
Using mmcache should increase your php content driven sites around 1-10 times their load times and bring your load down on the server also since your server isn't always re-compiling php pages over and over again

| Wildcard in DNS & Apache |
|

Here is a nice idea for people that have like webhosting or just run any websites with subdomains. Also i often type a url like ww.domain.com.
So a wildcard will catch any not matched dns entry and point it to a IP. Say I have this simple dns zone file
Code: NS ns1.domain.com.
NS ns2.domain.com.
NS ns3.domain.com.
domain.com. MX 5 flood.domain.com.
domain.com. MX 20 web2.domain.com.
domain.com. A 66.111.22.33
www CNAME domain.com.
Now I add the following to the end of the zone file for the wildcard
Code: *.domain.com. IN A 66.111.22.33
Now reload named.
Code: service named reload
So that will take all random subdomains people may try and then send them to the IP of my webserver for example. We can easily test that
Code: [root@web1 named]# host bla.domain.com
bla.domain.com has address 66.111.22.33
[root@web1 named]# host jy.rules.domain.com
jy.rules.domain.com has address 66.111.22.33
[root@web1 named]# host AHHHHHHHHH.domain.com
AHHHHHHHHH.domain.com has address 666.111.22.33
So now that bind is all setup we need to do the same for apache. You need to have your virtualhosting setup in apache for this to work
So we add the following simple section at the bottom of the httpd.conf file
Code: <VirtualHost 66.111.22.33>
DocumentRoot /var/www/html
ServerAlias *.domain.com
ServerName www.domain.com
</VirtualHost>
That is very simplified.. so you can always add more entries if needed like the logs or such. Now just restart apache
Code: service httpd restart
Now you should be able to enter ww.domain.com into your browser and it should take you to your website.

| Changing directorys like a stack |

Heres a little trick on how to change directorys like a stack with push and pop :)
push == add directory to the stack
pop == remote the last directory form the stack
The first thing we are going to do is change to a directory with push this done by
entering pushd /path/ as shwon below.
Code: [damian@localhost ~]$ pushd /home/damian/public_html
~/public_html ~
[damian@localhost public_html]$ pwd
/home/damian/public_html
[damian@localhost public_html]$
Now you can see that the directory has changed if we wanted to go back a directory we would
pop the directory like popd as shown below.
Code: [damian@localhost public_html]$ pwd
/home/damian/public_html
[damian@localhost public_html]$ popd
~
[damian@localhost ~]$ pwd
/home/damian
[damian@localhost ~]$
Well enjoy poping and pushing your directorys :)

Hi,
I installed debian starge on my server the other day, and also installed vncserver (or if it came with debian by default ..) on it. However, now that i try to reach it from outside, i get the password prompt of course. And thats then i struck me that i never got the option to choose a password for vncserver ...
So is there some default password for vnc that i can use? Cause i can connect to it, but i dont know the password hehe :)
