To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h domU-12-31-39-13-CD-47 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!

Squid Proxy Cache Server Installation and Configuration
Squid
is a proxy caching server. If you are Linux sysadmin, you can use squid
to control internet access at your work environment.This beginners guide will give a jump-start on how to setup squid on Linux to restrict internet access in an network.
Install Squid
You should install the following three squid related packages on your system.- squid
- squid-common
- squid-langpack
$ yum install squid
Check Configuration and Startup scripts
Apart from installing the squid related packages, it also creates the /etc/squid/squid.conf and /etc/init.d/squid startup script.By default Squid runs on 3128 port. You can verify this from the squid.conf file. You can also set the visible_hostname parameter in your squid.conf, which will be used in error_log. If you don’t define, squid gets the hostname value using gethostname() function.
# vim /etc/squid/squid.conf visible_hostname ubuntuserver httpd_port 3128Note: The http port number (3128) specified in the squid.conf should be entered in the proxy setting section in the client browser. If squid is built with SSL, you can use https_port option inside squid.conf to define https squid.
Start Squid and View Logs
Start the Squid proxy caching server as shown below.# service squid start squid start/running, process 11743Squid maintains three log files (access.log, cache.log and store.log) under /var/log/squid directory.
From the /var/log/squid/access.log, you can view who accessed which website at what time. Following is the format of the squid access.log record.
time elapsed remotehost code/status bytes method URL rfc931 peerstatus/peerhostTo disable logging in squid, update the squid.conf with the following information.
# to disable access.log cache_access_log /dev/null # to disable store.log cache_store_log none # to disable cache.log cache_log /dev/null
Squid Usage 1: Restrict Access to Specific Websites
This is how you can restrict folks from browsing certain website when they are connected to your network using your proxy server.Create a file called restricted_sites and list all sites that you would want to restrict the access.
# vim /etc/squid/restricted_sites www.youtube.com mail.yahoo.com
www.hotmail.com
www.gmail.com
Modify the squid.conf to add the following.
# vim /etc/squid/squid.conf acl RestrictedSites dstdomain "/etc/squid/restricted_sites" http_access deny RestrictedSites
Squid Usage 2: Allow Access to Websites Only During Specific Time
Some organization might want to allow employees to surf or download from the internet only during specific timeperiods.The squid.conf configuration shown below will allow internet access for employees only between 9:00AM and 18:00 during weekdays.
# vim /etc/squid/squid.conf acl official_hours time M T W H F 09:00-18:00 http_access deny all http_access allow official_hours
Squid Usage 3 : Restrict Access to Particular Network
Instead of restricting specific sites, you can also provide access only to certain network and block everything else. The example below, allows access only to the 192.168.10.* internal network.# vim /etc/squid/squid.conf acl branch_offices src 192.168.10.0/24 http_access deny all http_access allow branch_offices
Squid Usage 4 : Use Regular Expression to Match URLs
You can also use regular expression to allow or deny websites.First create a blocked_sites files with a list of keywords.
# cat /etc/squid/blocked_sites soccer movie www.example.comModify the squid.conf to block any sites that has any of these keywords in their url.
# vim /etc/squid/squid.conf acl blocked_sites url_regex -i "/etc/squid/blocked_sites" http_access deny blocked_sites http_access allow allIn the above example, -i option is used for ignoring case for matching. So, while accessing the websites, squid will try to match the url with any of the pattern mentioned in the above blocked_sites file and denies the access when it matches.
SARG – Squid Analysis Report Generator
Download and install SARG to generate squid usage reports.Use the sarg-reports command to generate reports as shown below.
# to generate the report for today sarg-report today # on daily basis sarg-report daily # on weekly basis sarg-report weekly # on monthly basis sarg-report monthly
Add the sarg-report to the crontab.
The reports generated by sarg are stored under /var/www/squid-reports. These are html reports can you can view from a browser.
$ ls /var/www/squid-reports Daily index.hyml $ ls /var/www/squid-reports/Daily 2010Sept1-2010Sept2 images index.html

How to Recover Deleted Files in Fedora / Ubuntu
foremost
is a forensics application to recover
files based on their headers, footers, and internal data structures.
Foremost can work on image files, such as those generated by dd,
Safeback, Encase, etc, or directly on a drive. This short article shows
how you can use foremost to recover deleted files.
Currently foremost can recover the following file types:
Please note that there's no guarantee that foremost will succeed in recovering your files, but at least there's a chance.
#yum install foremosrt
#apt-get install foremost
#apt-get install scalpel
Press Alt + F2 and type: gedit /etc/scalpel/scalpel.conf
and uncomment these lines:
After Scalpel has finished, you will find a folder called output in the directory from where you called Scalpel. The audit.txt contains a summary of what Scalpel has done and the pdf-0-0/ subdirectory contains the pdf files that Scalpel has recovered.
Before you run Scalpel the next time from the same directory, you must either delete/rename the current output/ directory (because Scalpel will not start if the output directory is already existing) or use specify another output directory.
Using Foremost
Foremost Syntax
Currently foremost can recover the following file types:
- jpg - Support for the JFIF and Exif formats including implementations used in modern digital cameras.
- gif
- png
- bmp - Support for windows bmp format.
- avi
- exe - Support for Windows PE binaries, will extract DLL and EXE files along with their compile times.
- mpg - Support for most MPEG files (must begin with 0x000001BA)
- wav
- riff - This will extract AVI and RIFF since they use the same file format (RIFF). note faster than running each separately.
- wmv - Note may also extract -wma files as they have similar format.
- mov
- ole - This will grab any file using the OLE file structure. This includes PowerPoint, Word, Excel, Access, and StarWriter
- doc - Note it is more efficient to run OLE as you get more bang for your buck. If you wish to ignore all other ole files then use this.
- zip - Note is will extract .jar files as well because they use a
similar format. Open Office docs are just zipâd XML files so they are
extracted
as well. These include SXW, SXC, SXI, and SX? for undetermined OpenOffice files. - rar
- htm
- cpp - C source code detection, note this is primitive and may generate documents other than C code.
Please note that there's no guarantee that foremost will succeed in recovering your files, but at least there's a chance.
2 Installing foremost
On Fedora and Ubuntu, foremost can be installed as follows:#yum install foremosrt
#apt-get install foremost
#apt-get install scalpel
Press Alt + F2 and type: gedit /etc/scalpel/scalpel.conf
and uncomment these lines:
pdf y 5000000 %PDF %EOF\x0d REVERSE
pdf y 5000000 %PDF %EOF\x0a REVERSEscalpel /dev/sda1 -o output After Scalpel has finished, you will find a folder called output in the directory from where you called Scalpel. The audit.txt contains a summary of what Scalpel has done and the pdf-0-0/ subdirectory contains the pdf files that Scalpel has recovered.
Before you run Scalpel the next time from the same directory, you must either delete/rename the current output/ directory (because Scalpel will not start if the output directory is already existing) or use specify another output directory.
Using Foremost
Foremost Syntax
foremost [-h][-V][-d][-vqwQT][-b][-o ] [-t ][-s ][-i ]
Available Options
-h Show a help screen and exit.
-V Show copyright information and exit.
-d Turn on indirect block detection, this works well for Unix file systems.
-T Time stamp the output directory so you don’t have to delete the output dir when running multiple times.
-v Enables verbose mode. This causes more information regarding the current state of the program to be dis-played on the screen, and is highly recommended.
-q Enables quick mode. In quick mode, only the start of each sector is searched for matching headers. That is,the header is searched only up to the length of the longest header. The rest of the sector, usually about 500 bytes, is ignored. This mode makes foremost run con- siderably faster, but it may cause you to miss files that are embedded in other files. For example, using quick mode you will not be able to find JPEG images embedded in Microsoft Word documents.
-V Show copyright information and exit.
-d Turn on indirect block detection, this works well for Unix file systems.
-T Time stamp the output directory so you don’t have to delete the output dir when running multiple times.
-v Enables verbose mode. This causes more information regarding the current state of the program to be dis-played on the screen, and is highly recommended.

Quick
mode should not be used when examining NTFS file systems. Because
NTFS will store small files inside the Master File Table, these files
will be missed during quick mode.
-Q Enables Quiet mode. Most error messages will be sup-pressed.
-w Enables write audit only mode. No files will be extracted.
-a Enables write all headers, perform no error detection in terms of corrupted files.
-b number Allows you to specify the block size used in foremost. This is relevant for file naming and quick searches. The default is 512. ie. foremost -b 1024 image.dd
-w Enables write audit only mode. No files will be extracted.
-a Enables write all headers, perform no error detection in terms of corrupted files.
-b number Allows you to specify the block size used in foremost. This is relevant for file naming and quick searches. The default is 512. ie. foremost -b 1024 image.dd
-k
number Allows you to specify the chunk size used in foremost.This can
improve speed if you have enough RAM to fit the image in. It reduces
the checking that occurs between chunks of the buffer. For example if
you had > 500MB of RAM. ie. foremost -k 500 image.dd
-i file The file is used as the input file. If no input file is specified or the input file cannot be read then stdin is used.
-o directory Recovered files are written to the directory directory.
-c
file Sets the configuration file to use. If none is speci-fied, the
file “foremost.conf” from the current direc-tory is used, if that
doesn’t exist then “/etc/fore-most.conf” is used. The format for
the configuration file is described in the default configuration
file included with this program. See the CONFIGURATION FILE section
below for more information.
-s number Skips number blocks in the input file before beginning the search for headers. ie.
foremost -s 512 -t jpeg -i /dev/hda1
Foremost examples
Search for jpeg format skipping the first 100 blocks
su -c foremost -s 100 -t jpg -i image.dd
Only generate an audit file, and print to the screen (verbose mode)
su -c foremost -av image.dd
Search all defined types
su -c foremost -t all -i image.dd
Search for gif and pdf
su -c foremost -t gif,pdf -i image.dd
Search for office documents and jpeg files in a Unix file sys-tem in verbose mode.
su -c foremost -v -t ole,jpeg -i image.dd
Run the default case
su -c foremost image.dd
image.dd means you need to enter your hardisk mount point i.e /dev/sda1 or /dev/sda2
