How To Perform HTTP-GET via Curl Commands inside PHP

PHP supports libcurl that allows you to connect and communicate to many different types of servers with many different types of protocols.

libcurl currently supports the http, https, ftp, gopher, telnet, dict, file, and ldap protocols. libcurl also supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, and user+password authentication.

Here's a quick scan of how I just wasted several days and couple of hours trying to integrate simple PHP curl codes with existing API backends from Enom and Namecheap. Currently Namecheap does not have publicly available integration interface that is as simple as 1-2-3 site installation.

Now the fun begins.

$url = 'API server host';
$curl;
$curl = curl_init();
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($curl, CURLOPT_URL, $url);
$result = curl_exec($curl);
curl_close($curl);
header('Content-Type: application/xml; charset=ISO-8859-1');
print $result;

By default, curl makes use of HTTP-GET unless explicitly specified to be false and as HTTP-POST method.

This PHP codes simply checks a specified particular domain TLD via PHP form, for the possibiblity of domain existence. That's it. As we all know, the free WHOIS and DOMAINTOOLS servers are limited by request for security reason, that is why this code has been created for some time. Note that the return results from Namecheap API server https://api.sandbox.namecheap.com comes in XML format.

Probability is, this is the same approach that has been utilized for desktop and web applications like twitter, entrecard, myblog, and even YMail and GMail - the difference is that the front-end differs, where a few of them enjoyed more of AJAX and SOAP. :) The rest are PHPs.

Furthermore, these codes can also be expanded to actually register domains, and even have a full-pledged DNS control and management system acting as domain registrar platform, like Godaddy, Namecheap, Onlinenic and Enoms.

Fedora 11 - HTML Doc Installation

Have you ever needed a tool that converts HTML source files, into indexed HTML, or adobe postscripts or even to adobe PDF files? Here's a quick post on how to convert HTML files into indexed HTML, postscript or adobe PDF file.

What is HTMLDOC?

HTMLDOC converts HTML source files into indexed HTML, PostScript, or Portable Document Format (PDF) files that can be viewed online or printed. With no options a HTML document is produced on stdout. The second form of HTMLDOC reads HTML source from stdin, which allows you to use HTMLDOC as a filter. The third form of HTMLDOC launches a graphical interface that allows you to change options and generate documents interactively.

HTMLDOC converts Hyper-Text Markup Language ("HTML") input files into indexed HTML, Adobe® PostScript®, or Adobe Portable Document Format ("PDF") files.

HTMLDOC supports most HTML 3.2 elements, some HTML 4.0 elements, and can generate title and table of contents pages. The 1.8.x releases do not support stylesheets. HTMLDOC can be used as a standalone application, in a batch document processing environment, or as a web-based report generation application.

How To Install HTMLDOC into Fedora 11?

HTMLDOC Installation on Fedora

HTMLDOC is supported by Fedora 11 yum repos. To install, simply

# yum -y install htmldoc

The above command will also install C++ user interface toolkit called fltk.

HTMLDOC Usage

Executing HTMLDOC binary launches a GUI window where in you can customize its default settings and feed in the required input files and eve specify the output file as shown from the captured HTMLDOC window below

# htmldoc

How To Reconfigure X From Terminal on Fedora 9

First time Fedora installation on untested hardware sometimes needs some tweaking encouragement and tips from time to time. At times, X just would not work. Sometimes, X is misconfigured and needs to be reconfigured. Reconfiguring X takes no standard approach depending on the type of video card you have from your box.

As long as you have access to shell or terminal, the chance of reconfiguring X successfully increases. 

How To Reconfigure X from Terminal on Fedora 9

If by chance, your screen  is showing display error message like Input Signal Out of Range, simply press Ctrl + F1 to gain access to your linux terminal. Super user details is required, enter your root as username and your root password. Backup Xorg conf file

# cp /etc/X11/xorg.conf /etc/X11.xorg.conf.BAK

During the old Redhat days, executing redhat-config-xfree86 should give you access to reconfigure X. But in Fedora, every redhat-config-* command is renamed to system-config-* commands. Issue

# system-config-display

If problem persists, go back to Ctrl + F1, press Ctrl + C to gain back shell access and try issuing

# system-config-display --reconfig

Issuing system-config-display gives you access to reconfigure your X and build your /etc/X11/xorg.conf X file. If the problem could not be resolved, try issuing

# system-config-display --reconfig --noui

to force the command not to use GUI on reconfiguring X in Fedora.  This command rebuilds xorg.conf file.

For every play around with the above command, remember to check X if it has been properly configured by pressing Ctrl + F7 and afterwards, hitting Ctrl + BackSpace. This should restart X daemon.

If all fails, and reconfiguring X using system-config-display --reconfig did not work, try to copy the original Xorg conf file like so

# cp /etc/X11/xorg.conf.BAK /etc/X11/xorg.conf

and edit it

# nano -w /etc/X11/xorg.conf

From the last few lines of the file, hack the Xorg conf file to have

Modes     "800x600" "640x400"

for the most basic display screen modes. 

Restart X by going back to Ctrl + F7 or by rebooting the system. Make sure that your system would start in level 5 by editing the file /etc/inittab . The file /etc/inittab should have the line

id:5:initdefault:

If the problem of reconfiguring X is still not solved, try changing and using a default VGA display driver like the ones from intel . Simply edit /etc/xorg.conf and have

#Drive    "nv"   # for nvidia cards

Driver     "intel"

under Device section. Save, exit, restart X and try again all previous commands until you get the system-config-display working. Most times, a tweak of video driver and modes from /etc/X11/xorg.conf should do it.

If you happen to have NVidia video card, simply head on here.

 

How To Selectively Archive and Backup MBox/IMAP Mails Using ArchiveMail

Maybe some of your mailboxes are quite large (eg, over 10,000 messages) and they are taking a while to load in your mail reader. Perhaps they are taking up too much space on your disk. Archiving old messages to a separate, compressed mailbox is possible. Here's a quick post on managing your mbox/imap mailboxes directly. Using this tool, you can move mail messages older than x days to a separate mbox file, or even to a compressed backup file.

What is Archivemail?

Archivemail is a tool written in Python for archiving and compressing old email in mailboxes. Archivemail can move specific and/or group of mbox/imap email messages older than the specified number of days to a separate mbox format mailbox that is compressed with gzip, or optionally just delete old email or simply archive it to separate mbox/imap file.

Here are several advantages of implementing archivemail:

1. Your mail reader will get a huge performance boost loading and reading your mail.
2. You will be taking up less disk space, since old mail will be compressed. (Mail usually compresses quite nicely.)
3. You won't be confronted with semi-obsolete mail all the time.

Features overview

* Supports archiving IMAP, mbox, MH and Maildir format mailboxes.
* Old mail can be either archived or just deleted.
* The age in days that is considered old is configurable – it defaults to 180 days. You can also set an absolute limit date.
* Messages that are flagged important are not archived or deleted unless explicitely requested.
* Can be configured to preserve unread mail.
* Can be configured to only archive messages over a given byte size.
* Stores the compressed archive mailboxes in a directory of your choice, with an extension of your choice.
* Easy read-only testing, not touching your valuable data.
* Supports IMAPS/SSL.
* When archiving IMAP mailboxes, the message selection can be refined by extending the underlying IMAP SEARCH command with arbitrary search keys (you will have to cope with the raw IMAP protocol, though).

How To Install ArchiveMail in Fedora 9

Simply issue yum

# yum -y install archivemail

Sample usage of archivemail

To archive mails older than 10 days, simply

# archivemail -d 10 root

legend:
10 - number of past days
root - mbox/imap mail

Result:
root:
archived 133 of 540 message(s) (128.0kB of 142.6MB) in 13.3 seconds

The above archivemail command moves all mbox mails that is older than 10 days and store it to root_archive.tgz as a backup mbox file. If the archive file is already existing, archivemail simple appends any results to existing archivemail archive.


To archive mbox mails older than 2008-08-10

# archivemail -D "2008-08-10" root

To specify destination folder when archiving mail, simply make use of -o parameter

# archivemail -d 30 root -o /root/archive

To delete all mails rather than archiving it, simply use archivemail as shown

# archivemail --delete -d 100 root

Use the above command with caution as it handling the mbox/imap mails directly.

To copy archived mails rather than archive it, simply

# archivemail -v --copy -d 360 mymail


By default, all archivemail output files are compressed and follow the format mailbox_archived.tgz file format. You can override the compression setting by issuing

# archivemail -d 15 root --no-compress

The above command does not compressed the file.

If you wish to execute an archivemail dry run, without actually arching mail, simply

# archivemail -v -n -d 15 mymail

All is done.

How To Scan DNS BIND Conf File For Errors On Fedora

What is BIND?

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. BIND includes a DNS server (named), which resolves host names to IP addresses; a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating properly.

When you install BIND on Fedora, BIND comes with command line utilities that you can use to check your DNS status, DNS statistics and even DNS configuration file.

Here's a quick post on how to check your DNS BIND Conf file for errors. As a requirement, DNS BIND should be currently installed from your Fedora box.

To check and scan DNS BIND configuration file for possible errors, simply issue

# named-checkconf /etc/named.conf

If you are running a chrooted-BIND, simply issue

# named-checkconf /var/named/chroot/etc/named.conf

Issuing the above commands would display any erroneous DNS BIND configuration lines. If you did not see any output from your screen, that is a good sign that your DNS BIND service would start normally.

As an example result of using named-checkconf :

# named-checkconf /var/named/chroot/etc/named.conf
/var/named/chroot/etc/named.conf:28: missing ';' before '}'

The above simply means that DNS bind is expecting a character from line 28 which is currenty missing from DNS BIND configuration file. DND BIND is expecting either the ; or } character , which is usually located at the end line from the DNS conf file.

How To Convert White Spaces To Line Break

At times, when dealing with text file that contains numeric values that are separated by white space, there is a need to convert white spaces between numbers into line breaks or new lines.

Here's a quick tip on how to convert white space to new lines or line breaks.

As an example, a created text file contains numeric values as shown below


# cat file.txt
123 456 768
312 654 987
123 456 768
312 654 987
123 456 768
312 654 987



To remove white spaces of text file located between numbers as shown above, simply use linux tr command to convert those white spaces into line breaks or new lines.

# cat file.txt | tr ' ' '\n'

Results:

123
456
768

How To Install PHPMyAdmin on Fedora 9

phpMyAdmin is an opensource tool written in PHP intended to handle the administration of MySQL database and table over the web. Currently, phpmyadmin can create and drop databases, create/drop/alter tables, delete/edit/add fields, execute any SQL statement, manage keys on fields, manage privileges, export data into various formats and is being distributed in more than 50 languages.

PHPMyAdmin Installation on Fedora

Fedora 9 ISO images comes with PHP, MySQL and Apache as part of its distribution release. It is a requirement for PHPMyAdmin to work that the below services are currently installed, and running.

• MySQL as Backend Database Server
• Apache as HTTP Web server - Installation Here
  
• PHP scripting language - Installation Here
  

Step One

To install PHPMyAdmin using yum, simply issue

# yum -y install phpMyAdmin.noarch

Step Two

PHPMyAdmin Security Access

By default installation, phpmyadmin administration page can only be accessed from localhost via web browser for added security. If you wish to access phpmyadmin page from multiple hosts, modify phpmyadmin conf page as shown below

# vi /etc/httpd/conf.d/phpMyAdmin.conf

and edit the necessary settings. For example, if you require phpmyadmin web page to be accessible from a computer host with an IP address of 123.123.123.123, edit phpMyAdmin.conf to reflect the below similar lines


order deny,allow
deny from all
allow from 127.0.0.1
allow from 123.123.123.123


Save, exit and reload apache web server.

# service httpd reload

Step Three

PHPMyAdmin User Access Authentication

Before PHPMyAdmin can successfully connect to MySQL backend database, a MySQL username and password is needed to gain authorization to MySQL database server . To do this, simply edit PHPMyAdmin conf file like so

# vi /etc/phpMyAdmin/config.inc.php

and modify the similar lines.

$cfg['Servers'][$i]['auth_type'] = 'http'; // Authentication method (config, http or cookie based)?
$cfg['Servers'][$i]['user'] = 'USERNAME'; // MySQL user
$cfg['Servers'][$i]['password'] = 'PASSWORD'; // MySQL password (only needed

Replace USERNAME and PASSWORD with your MySQL username and password respectively.

By default, PHPMyadmin connects to MySQL via localhost with default port and socket. If you wish to modify these settings, change the below similar lines

$cfg['Servers'][$i]['host'] = 'localhost'; // MySQL hostname or IP address
$cfg['Servers'][$i]['port'] = ''; // MySQL port - leave blank for default port
$cfg['Servers'][$i]['socket'] = ''; // Path to the socket - leave blank for default socket

to fit your needs.

And finally, launch your browser and point it to your PHPMyAdmin web page.

For localhost
http://localhost/phpMyAdmin/

For non-localhost apache server
http://123.123.123.123/phpMyAdmin/

Enter your MySQL username and password.

When starting K3B, a friend of mine complained about a MP3 decoder message that appears everytime he starts K3B. The K3B warning message is similar below

Mp3 Audio Decoder plugin not found.
K3b could not load or find the Mp3 decoder plugin. This means that you will not be able to create Audio CDs from Mp3 files. Many Linux distributions do not include Mp3 support for legal reasons.
Solution: To enable Mp3 support, please install the MAD Mp3 decoding library as well as the K3b MAD Mp3 decoder plugin (the latter may already be installed but not functional due to the missing libmad)

K3B is an opensource CD/DVD linux burning software that has a lot of useful and creative features on handling copying CD/DVD images and data. However, there are propriety library modules and rpms that were not included with the releases of Fedora for legal reasons.

To make use of a feature-rich and easy to handle CD/DVD burning application, here's how to install K3B Audio MP3 decoder.

Step One.

Install K3B. Simply instructions can be found here.

Step Two

How To Install Python Module for Google Data API Services on Fedora

Recent repetitive job for the past several days triggers my subtle and sleeping mind from doing another playful hobby. Just a thought, I have convinced myself, to do some boring but interesting play, atleast give Google API a try.That is, manage and administer Google data like Blogger posts via Google Data API connecting locally using python, or even Java, from my Fedora desktop.

Did my research and found some leads.

I managed to learn few tricks and Google API tips on managing posts (Google data) to and from Google blogger using Google API, :) it is tedious but interestingly open. You can learn it too!

If you wish to access your google data and services using google API via phyton, this can be done by using Google Data APIs or Google data. This Google API provides simple protocol for reading and writing data on Google web.

Each of the following Google services provides a Google data API:

    * Base
    * Blogger
    * Calendar
    * Picasa Web Albums
    * Spreadsheets
    * Documents List
    * Contacts
    * YouTube
    * Google Apps Provisioning
    * Code Search
    * Notebook

Sourced from Google API.

The Google Data Python Client Library provides a library and source code that make it easy to access data through Google Data APIs.

Now, one way to access Google data using Fedora is by using and installing python modules.

What is Python GData Module?

Python Gdata, sometimes referred to as python-gdata, in shortest definition, is a Python module for accessing online Google services, such as:

- Blogger
- Calendar
- Picasa Web Albums
- Spreadsheets
- YouTube
- Notebook

If you need to experiment stuff with Google data via python, python gdata installation is the first step.

How To Install Python GData on Fedora 9

# yum -y install python-gdata.noarch

The above would install the necessary requirements for you to be able to launch and execute python commands to access your Google data via web. Several requirements and dependencies are shown below:

  ElementTree - For XML parsing
  httplib - Part of the core Python library since version 2.0, so it should
already be present.
  urllib - For URL creation and URL encoding, should already be present in
current versions of Python.

Shown below is a snipped python code via python-data on managing and playing around with Google blogger data, as an example.

    # Demonstrate how to publish a public post.
    public_post = self.CreatePost("Back from vacation",
      "I didn't want to leave Aruba, but I ran out of money :(
",
      "Post author", False)
    print "Successfully created public post: \"" + public_post.title.text + "\".\n"

    # Demonstrate various feed queries.
    print "Now listing all posts."
    self.PrintAllPosts()
    print "Now listing all posts between 2007-04-04 and 2007-04-23."
    self.PrintPostsInDateRange("2007-04-04", "2007-04-23")

    # Demonstrate updating a post's title.
    print "Now updating the title of the post we just created:"
    public_post = self.UpdatePostTitle(public_post, "The party's over")
    print "Successfully changed the post's title to \"" + public_post.title.text + "\".\n"

Using this approach, and several hours of python programming, steps can be taken to extend your knowledge and  accomplish simple to complex Google API functions such as:

• blogger batch postings
• blogger batch deletions 
• add/edit/delete/view of blogger posts
  
• blogger posts/posts tags edits indirectly or directly and more
  

or even migrate and repost your thousand wordpress backup XML data to blogger. This has been possible with an extra help from the nice and wonderful Google staff like Mr. Jeffrey and Mr. Trevor.

I have to contact them since Blogger data posting has a default 50 limit posts per day quota. Thanks for the override help! :)

More Google API documentation can be found here.

Enjoy and have fun!

How To Install Beautiful Soup in Fedora 9

What is beautiful soup?

Beautiful Soup is a Python HTML/XML parser designed for quick turnaround projects like screen-scraping. Three features that makes Beautiful Soup powerful:

• Beautiful Soup won't choke if you give it bad markup.
• Beautiful Soup provides a few simple methods and Pythonic idioms for navigating, searching, and modifying a parse tree.
• Beautiful Soup automatically converts incoming documents to Unicode and outgoing documents to UTF-8.

Beautiful Soup parses anything you give it.

Valuable data that was once locked up in poorly-designed websites is now within your reach. Projects that would have taken hours take only minutes with Beautiful Soup.

Beautiful Soup Installation on Fedora 9

Launch yum installer to install beautiful soup rpm for Fedora 9 as shown below.

# yum -y install python-BeautifulSoup.noarch

Beautiful soup requires python to be currently installed from the system.

More information can be obtained from here along with beautiful soup documentation.

How To Install PHP Tidy on Fedora 9

How To Install Tidy on Fedora 9

What is Tidy?

Tidy is fundamentally a tool that reads in HTML cleans it up and writes it out again. It was developed as a program you run from the console prompt, but there are GUI encapsulations available, e.g. HTML-Kit, which you might prefer.

Tidy is a standard PHP module provides tidy library support. Tidy is currently available for PHP 4.3.x and PHP 5 as a PECL extension. Tidy can easily be installed to Fedora OS.

Tidy Installation on Fedora 9

The hard way to install tidy is by manual installation, which was based from PHP site here. The below code is a sniff copy from it taken from PHP tidy help site:

gunzip tidy-xxx.tgz

tar -xvf tidy-xxx.tar

cd tidy-xxx

phpize

./configure && make && make install

Alternatively, fedora repo supports tidy rpm, and can easily be installed using yum installer.

Step One

To install PHP Tidy module and tidy shared libraries for fedora, simply

# yum -y install libtidy.i386

# yum -y install php-tidy.i386


The default PHP-tidy conf file would be pointed to /etc/php.d/tidy.ini with a tiny library file to /usr/lib/php/modules/tidy.so .

To install tidy for Fedora as a stand alone terminal component, simply

# yum -y install tidy

If you want to use tidy with python, optionally you can install tidy phyton wrapper like so

# yum -y install python-tidy.noarch

and for perl programmers that makes use of tidy, simply install tidy perl tools

# yum -y perltidy.noarch

# yum -y perl-HTML-Tidy.i386


There is no need to edit php.ini for tidy to properly work. However, for PHP tidy reference, the default tidy configuration file set inside /etc/php.ini is currently pointed to

/usr/local/lib/php/default.tcfg

which does not bother my need at all.

More PHP TIdy info can be read here.

Adobe® Flash® Player 10, code-named "Astro," introduces new expressive features and visual performance improvements that allow interactive designers and developers to build the richest and most immersive Web experiences.  These new capabilities also empower the community to extend Flash Player and to take creativity and interactivity to a new level.

The Flash Player has been improved to support new and cool internet browsing features such as 3D effects, advanced 3D layouts and more. You can visit Adobe Flash Player 10 cool features here.

Adobe Flash Player 10 Installation into Firefox 3 under Fedora 9

To install flash 10 with your Firefox browser under Fedora 9 OS, simply follow the following steps.

Step One

As root, uninstall any existing adobe flash player named flash-plugin rpm package like so

# rpm -qa | grep flash-plugin | xargs rpm -e

Uninstall Fedora's gnash and swfdec rpm packages like so

# rpm -qa | grep swfdec | xargs rpm -e
# rpm -qa | grep gnash | xargs rpm -e

Uninstalling Fedora's mozplugger rpm is not required but can be optional. Removing mozpluggerrc would disable other browser plugins of Firefox. If you wish to uninstall mozpluggerrc rpm package, simply

# rpm -qa | grep mozpluggerrc | xargs rpm -e

Step Three

For i386 machines, download and install every rpm that you can find from this link

To install, simply

# rpm -ivh curl-7.18.2-3.fc9.i386.rpm
# rpm -ivh curl-debuginfo-7.18.2-3.fc9.i386.rpm
# rpm -ivh libcurl-7.18.2-3.fc9.i386.rpm
# rpm -ivh libcurl-devel-7.18.2-3.fc9.i386.rpm

If you have any existing rpm package simply use rpm upgrade like so

# rpm -Uvh curl-7.18.2-3.fc9.i386.rpm
# rpm -Uvh curl-debuginfo-7.18.2-3.fc9.i386.rpm
# rpm -Uvh libcurl-7.18.2-3.fc9.i386.rpm
# rpm -Uvh libcurl-devel-7.18.2-3.fc9.i386.rpm

If you your platform is not of i386 type, locate your machine's architecture here and download those rpms located under platform folder and install it into your F9 using the same rpm command as shown recently.

If you have earlier Fedora versions, you could get libcurl rpm of your old Fedora versions here

Step Four
Now, get back to your terminal window. Ensure that curl library is within the search path

# updatedb ; locate libcurl.so.3
/usr/lib/libcurl.so.3

Ensure also that Firefox binary can be found from default path as well


# which firefox
/usr/bin/firefox

Step Five

Download Adobe Flash Player rpm plugin and install it via rpm


# wget -c http://download.macromedia.com/pub/...081108.i386.rpm



# rpm -ivh flashplayer10_install_linux_081108.i386.rpm

The above adobe flash rpm is for compiled for Fedora 9 i386 platforms, no other rpms are available for other linux platforms as of this posting.

Step Six

Go to /usr/lib/mozilla/plugins/ folder

# cd /usr/lib/mozilla/plugins/
# ls -la /usr/lib/mozilla/plugins/

and make sure you have the following lines

lrwxrwxrwx 1 root root 39 2008-08-20 08:40 libflashplayer.so -> /usr/lib/flash-plugin/libflashplayer.so

Step Seven

Restart your firefox browser and head on to www.youtube.com to test your latest installation of adobe flash player 10.

Congratulations, you've just installed Adobe Flash Player 10!

Adobe Flash Player 10 Installation Verification
Launch Firefox browser and enter about:config as your URL . Check for adobe flash plugin lines.

Troubleshooting

How To Monitor and Be Informed of IP Address Changes From Your Network

An IT client enters your company, your boss ordered you to provide a browsing local IP address for that client's laptop for one week. Your boss gave emphasis to also monitor his IP address changes if any and let him be informed immediately for such IP address changes. But you don't have access to your client's laptop. And you don't want to request access from him as well as he would immediately comprehend your intentions somehow.

And so, you provided him his temporary browsing IP address as your LAN does not support DHCP nor boot from network services. How would you monitor and log any possible IP address changes coming from the said IT client's laptop.

Introducing Arpwatch

The arpwatch package contains arpwatch and arpsnmp.  Arpwatch and arpsnmp are both network monitoring tools.  Both utilities monitor Ethernet or FDDI network traffic and build databases of Ethernet/IP address pairs, and can report certain changes via email. In short, arpwatch  is a linux network monitoring tools for tracking IP addresses on your network.

Arpwatch Installation

# yum -y install arpwatch

Monitoring IP Address Changes By Email via Arpwatch

Edit /etc/sysconfig/arpwatch and make sure the below similar conf files exists

OPTIONS="-u arpwatch  -e ver -s 'Arpwatch'"

Save and exit.

Make sure your system is configured to accept and deliver mails.

Start Arpwatch Service

# service arpwatch start

Stop Arpwatch Service

# service arpwatch start

Permanent Arpwatch Startup Between Reboot

# chkconfig --levels 35 arpwatch on

Monitoring IP Address Changes By Log via Arpwatch

By default, arpwatch send its log details to /var/log/messages. To monitor all arpwatch log messages

# tail -f /var/log/messages | grep arpwatch

# cat /var/log/messages | grep arpwatch

Monitoring IP Address Conflicts By Log via Arpwatch

To list down all IP address changes occurrences within your network reachable by your current IP address configurations

# cat /var/log/messages | grep arpwatch | grep 'flip\|flop'

Tracing IP Address Changes using Arpwatch

Get the last and known IP address changes from the target host

# cat /var/log/messages | grep "192.168.2.33"

Tracing MAC Address of IP Address Changes using Arpwatch

Retrieve all MAC Address of all host that changed their IP address to 192.168.2.33 and count their occurrences

#  cat messages | grep '192.168.2.33'

Aug 14 18:05:49 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f
Aug 14 18:05:54 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f
Aug 14 18:06:05 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f
Aug 14 18:06:31 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f

Filter and  count all occurrences using grep, awk, sort and uniq linux command as shown

#  cat messages | grep '192.168.2.33' | awk '{print $8}' | sort | uniq -c

Tracing Other IP Address Changes Used by Target Host using Arpwatch

From the recent command, copy the MAC Address and use it as a grep filter from arpwatch log file. For example, using 0:2:6f:46:74:f as the target MAC Address, simply

# cat /var/log/messages | grep arpwatch | grep '0:2:6f:46:74:f'

Aug 16 14:03:51 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f
Aug 16 14:04:03 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f
Aug 16 14:04:03 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f
Aug 16 14:04:03 ver arpwatch: bogon 192.168.2.33 0:2:6f:46:74:f

The above would give you all details of IP address changes coming from the source host including the source MAC address.

Taken from the result is the MAC Address 0:2:6f:46:74:f . You can further filter out and count the number of occurrences by using grep and awk like so

# cat messages | grep arpwatch | grep '0:2:6f:46:74:f' | awk '{print $7}' | sort | uniq -c

32365 192.168.2.33
5130 192.168.100.33

The above shows more than 32,000 occurrences of bogon from 192.168.2.33 and more than 5,000 from 192.168.100.333. You can further filter out by adding IP address changes only by using flip flop filter word

# cat messages | grep arpwatch | grep 'flop' | grep '192.168.2.33' | awk '{print $7}' | sort | uniq -c

All is done
