Centos: Squid + Report + Webmin gui

1) to install WEBMIN administration gui , you first have to manually ad the repository for YUM:

$ vi /etc/yum.repos.d/webmin.repo

----- add ----
[Webmin]
name=Webmin Distribution Neutral
#baseurl=http://download.webmin.com/download/yum
mirrorlist=http://download.webmin.com/download/yum/mirrorlist
enabled=1
----- add ----

2) then you have to download & install the webmin GPG public key:

$ wget http://www.webmin.com/jcameron-key.asc
$ rpm --import jcameron-key.asc

3) install webmin with yum:

$ yum install webmin

4) at this point you should have you GUI already running on port 10000:

open url: http://servername:10000

5) now you can install SQUID and SARG (squid analysis report generator):

$ rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
$ yum install squid sarg

$ find / -name sarg.conf

6) UPDATE:

due to some needs, i ended up using the latest SARG version instead of the one supplied via YUM which is quite old and lacking of some nice features!

So these are the steps i followed:

1) unistalled sarg via YUM --> yum unistall sarg
2) download latest SARG --> wget http://sourceforge.net/projects/sarg/files/latest/download
3) extract it to /usr/src --> tar xvzf sarg.latest.tgz
4) install it --> basically you have to follow the isntruction in the README file

$ cd /usr/src/sarg-2.3.8
$ ./configure
$ make
$ sudo make install

remember to update your /etc/sarg/sarg.conf for your needs, especially for the folder where you want to save your reports.

NOTE for WEBMIN --> be sure to have the same config parameters in your sarg.cong and in your webming interface.

5) i installed my own version of cronjob to create a report every 15 minutes:

*/15 9-19 * * * /usr/local/bin/sarg -d day-0 -f /etc/sarg/sarg.conf -n

6) last but not least, i also added an "hostalias" file to summarize the logs coming from the same domains:

--- add this line in the /etc/sarg/sarg.conf ---
hostalias /etc/sarg/hostalias

--- and add a new file named /etc/sarg/hostalias containing something like that ---
*.googlevideo.com www.googlevideo.com
*.googlevideo.com:443 www.googlevideo.com

DOS Batch to backup virutalbox machines

This DOS script can be used to schedule backups of your virtuabox machines.

The backup consist in a simple copy of the VMs file into a backup folder.
But this script, in case of a RUNNING machine, will also change the state of the vm to SAVESTATE before proceding with the backup, and will bring it back to RUNNING after the copy is completed.

Requirements:

gnugrep must be installed (download it from here . PS: remember to dowload also the "Dependencies" package form here, which contains the required DLLs if you don't already have it);
change the 3 variabiles (highlithed in red) according to your needs (without trailing backslash):

VBDIR --> the location of the virtualbox manager installation
VMDIR --> the base forder of your virtualmachines files
BAKDIR --> the folder where you want to copy the VMs to

create as many SUBSCRIPT as you need, one per each VM you want to backup;
in each SUBSCRIPT, update the MYVM (yellow) variable with the name of the virtual machine (the one you see in the virtual box manager);

Script:

@echo off

set VMDIR="c:\virtual_machines"
set VBDIR="C:\Program Files\Oracle\VirtualBox"
set BAKDIR="D:\Backup\VM"

date /t > %BAKDIR%\bak.log
time /t >> %BAKDIR%\bak.log
@echo using virtualbox bin folder: %VBDIR%
@echo using virtualbox machines folder: %VMDIR%
@echo using backup folder: %BAKDIR%
cd /d %VBDIR% >> %BAKDIR%\bak.log
