They’re few tools out there which are most common in use to do benchmarking and stess test on webservers. One of them “the most common one”is called “ab” or apache benchmark Check it out here another very common tool is called flood Check it here Flood seems to be the newer and most accurate tool to use for stress testing unfortunately it has one weakness. It only works with configuration file which is in xml format. So every time before you start it you have to generate a new xml file to suite your needs. Also a tool recommended to me in the #apache in the irc.freenode.net network is called “jmeter”, it’s located here . I personally didn’t tested it because it uses Java as a back end. While googling around I also have stucked on this interesting project PHPSPEED although I wasn’t able to test it looks like a promising test suite.END—–

Apache Benchmarking
Monday, January 14th, 2008How to use wget and curl via HTTP Proxy server / How to set a HTTPS proxy server on a bash shell on Linux
Wednesday, January 27th, 2016 
I've been working a bit on a client's automation, the task is to automate process of installations of Apaches / Tomcats / JBoss and Java servers, so me and colleagues don't waste too
much time in trivial things. To complete that I've created a small repository on a Apache with a WebDav server with major versions of each general branch of Application servers and Javas.
In order to access the remote URL where the .tar.gz binaries archives reside, I had to use a proxy serve as the client runs all his network in a DMZ and all Web Port 80 and 443 HTTPS traffic inside the client network
has to pass by the network proxy.
Thus to make the downloads possible via the shell script, writting I needed to set the script to use the HTTPS proxy server. I've been using proxy earlier and I was pretty aware of the http_proxy bash shell
variable thus I tried to use this one for the Secured HTTPS proxy, however the connection was failing and thanks to colleague Anatoliy I realized the whole problem is I'm trying to use http_proxy shell variable
which has to only be used for unencrypted Proxy servers and in this case the proxy server is over SSL encrypted HTTPS protocol so instead the right variable to use is:
https_proxy
The https_proxy var syntax, goes like this:
proxy_url='http-proxy-url.net:8080';
export https_proxy="$proxy_url"
Once the https_proxy variable is set UNIX's wget non interactive download tool starts using the proxy_url variable set proxy and the downloads in my script works.
Hence to make the different version application archives download work out, I've used wget like so:
wget –no-check-certificate –timeout=5 https://full-path-to-url.net/file.rar
For other BSD / HP-UX / SunOS UNIX Servers where shells are different from Bourne Again (Bash) Shell, the http_proxy and https_proxy variable might not be working.
In such cases if you have curl (command line tool) is available instead of wget to script downloads you can use something like:
curl -O -1 -k –proxy http-proxy-url.net:8080 https://full-path-to-url.net/file.rar
The http_proxy and https_proxy variables works perfect also on Mac OS X, default bash shell, so Mac users enjoy.
For some bash users in some kind of firewall hardened environments like in my case, its handy to permanently set a proxy to all shell activities via auto login Linux / *unix scripts .bashrc or .bash_profile that saves the inconvenience to always
set the proxy so lynx and links, elinks text console browsers does work also anytime you login to shell.
Well that's it, my script enjoys proxying traffic 🙂
How to Remove Firefox TABS all time Moving Backward / Forward (Waiting) Wheel cursor – Browser and OS Wheel Ring cursor might affect hypnotically
Monday, September 7th, 2015 
I've been annoying for quite a long time by the the Clockwise moving backward and Forward Wheel (Ring) on Top of browser Tabs everytime I navigate to a new Internet domain or request a resource on the Net.
I'm aware that seeing the wheel all the time move back and forward is a very bad manipulation technique that is often used in advertisements in old movies and some advertisements in the start of the video . I'm talking about the infamous backward counting technique in a Circle (it was moer commonly used in the dawn of Television) aiming to induce watchers mind into hypnotic state …
Those who have a degree in psychology or have been into marketing or human resources fields or any field involved where you have to influence the masses are already aware of the backward counting methology which has been practiced heavily by hypnosis practisioners such as Sigmund Freud, to induce any kind of hypnotic state the hypnotist always asks the object of hypnotism to watch closely into a moving back and forwards clock, often accompanied by counting backwards …
Well my Theory here is that the same techniques is well aware of those who planned Windows OS in which if you remember the Sand Clock has been substituted in Windows 7 / 8 and Windows 10 with the rotating back and foward Wheel for the reason that this aims to influence people mind to go into Alpha state from Beta state and thus make them feel more relaxed while doing stuff on the PC.
One thing to mention here is Back and Forward wheel is not only into OS level it has been heavily adopted by leading Software as a Service (SAS) UIs such as Google's and probably more importantly Youtube (have you noticed the Cycling Wheel when waiting for a Youtube movie to Load), the Wheel is also heavily incoruprated in most if not all biggest Websites on the Net. Even If you have noticed these days Google's Cycling (Waiting) Wheel is not only Cycling but has the colorful programming incorporated.
Well probably many people who use computers daily did not really realize that the Computer OS and Programs GUI Interface they're using is influencing their mind and some famous psychological methods such as color programming and hypnotic tricks could be used more or less.
In that regard as a Firefox user I decided to change tne Back and Forward Wheel with another one which will not trigger my subconsciousness / mind all the time while browing on the Net into Alpha State. As I'm not a Firefox expert and my quick research on search Engines on how to achieve changing or removing the Browser Tabs all time turning wheel did not led me to nothing positive, I've consulted the experts in irc.freenode.net #firefox.
As always the guys were helpful and pointed me out to UserStyles.org website's Static-Throbbler CSS. I've mirrored the CSS script under a name remove-firefox-tab-wheel-script.css in case if UserSpace.org disappears in future, below is also a paste of the script:

To use the script you will first need to install the Stylish FF plugin, then:
1. Enable Stylish plugin and Restart firefox when prompted
2. Click on Write New Style
3. Paste above CSS script and click on Save button
Now instead of the moving wheel you will get just a circle appearing as a static image while the page is loading.
If you want to absolutely remove any circles or images and show nothing when loading, e.g. not have any mean to monitor whether page is loaded or not, but also make it easier for the eye I even finally decided to completely remove the all time moving Wheel from Firefox Tabs even the static picture out using below CSS script with Stylish:
@namespace url(https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul); @-moz-document url(chrome://browser/content/browser.xul) { .tab-throbber { list-style-image: none !important; animation-name: none !important; } .tab-throbber[progress] { list-style-image: none !important; } }
After all even after removing the FF Tabs wheel, there is the Status being printed down the webpage, showing text based the connection status. I find this kind of page loading status much less agressive and preferrable, than the current verions Firefox 4 onwards ..
One other thing I do to prevent the annoying Windows OS default Theme wheel is to change it to the old fashioned sand clock as well as bring back the theme of Windows 7 / 8 to Classic Theme of Win 2000, as I believe this reduced the level of zoombification the PC imposes on self 🙂
Enjoy!
Axion Estin – It is Truly Meet feast in Bulgarian Orthodox Church
Thursday, June 11th, 2015Today is a glorious feast in Eastern Orthodox Churches (especially in Slavonic ones) because on this day an ArchAngel Gabiel on Holy Mount Athos in year 773 handed an Angel song in praise of the Theotokos (Virgin Mary), Mother of our Lord and Saviour Jesus Christ.
Liturgical use
The hymn is chanted at Matins, Compline, and other services; but its most important occurrence is at the Divine Liturgy, where it is chanted at the conclusion of the Anaphora. The second half of the hymn, "More honorable…" is frequently chanted before the dismissal which concludes services.
Often, the chanting of this hymn is followed by either a metania or a prostration.
It is truly meet In Church Slavonic
Досто́йно ’е́сть ’я́ко вои́стину блажи́ти Тѧ֨, Богоро́дицу,
Присноблаже́нную ’и Пренепоро́чную ’и Ма́терь Бо́га на́шего.
Честне́йшую херуви́мъ ’и сла́внейшую безˈ сравне́ния серафи́мъ, безי ᾿истле́ния Бо́га Сло́ва ро́ждшую,
су́щую Богоро́дицу, Тя֙ велича́емъ.
It is Truly Meet in Bulgarian / Достойно есть
Достойно е, наистина, да Те облажаваме, Богородице,
винаги блажена и пренепорочна и Майка на нашия Бог.
По-чтима от херувимите и несравнено по-славна от серафимите,
нетленно родила Бог Слово, същинска Богородица, Те величаем.
All the World rejoices in You Holy Icon
Axion Estin (Greek) – It is truly meet
It is truly right to bless thee, O Theotokos,
thou the ever blessed, and most pure, and the Mother of our God.
Thou the more honorable than the cherubim,
and beyond compare more glorious than the seraphim,
who without corruption gavest birth to God the Word,
thou the true Theotokos, we magnify thee.
How to remove Google Logo from Searches in Firefox and Chrome and Safari Web browsers – Disable seeing Annoying Google Doodles content with ABP
Tuesday, May 26th, 2015 
Most of people nowadays are using Google as a default search engine for different reasons, some because of its popularity and most importantly because Google is considered the Largest and most used and superior in quality Internet Search Engine in the World as of time of writting this post.
However as most (if not all) Companies and Corporations nowdays in this terrible freedom enslaving Globalistic world, Google's popularity is not only a result of their superiority of service but a consequence of 17 years constant branding (or better to say user brainwashing) to addict peoples arround the world to their colorful logo and their Loud name GOOGLE (contains 2G's 2O's 1L and 1E or as it might be associated subsconsciously = Le, 2 G, 2 O or LE 2 GO – looks pretty much like the English LET GO – doesn't it??) .
Color programming has become a popular way for companies and brands to keep our minds affected the Colorful addiction and has been definitely quite seriously researched throughout World War I and World War II and Post war times by Governments and Psychological institute studies some of which tried to call it and name it as NLP (Neuro Linguistic Programming) and made a pseudo-science that is more of a spiritual new age occult thing than really based on facts. I guess some of this studies were put in action by most if not all big companies to influence their customer / users.
Google's Logo
Some example that such a mind psyche manipulation techniques are reality could be seen by simply comparing the Color Gamma of Google's Logo, Microsoft Flag (See your start button logo), Ebay Logo, Google Play's logo, Microsoft (Windows)Flag logo, Windows Media Player, Google Chrome, Microsoft Visual Studio, Apple's Old Logo … etc. etc. and a number of key applications we use daily is not a coincidence but a smartly crafted methodology to make people regularly exposed to combination of colors be psychologically influenced and attracted by the Colorful flag message not only in these company Software programs but also in daily products we buy from Shops / Supermarkets.
Windows Flag (Also present on every Windows PC in the start button and during PC boot)
However color programming that Google inflicts (is not really a prooved science but is based on a number of occult gnostic believes combined with some pseudo scientific research on associative human thinking).
Hence these colorful manipulation / programming technique so much adopted by companies is believed to effect on adult people and kids throughout the world because even from kids we're being exposed to this colors in many children books, cartoons cartoons and most importantly by the market which produces this "interesting" entertaining fun colorful kid toys.
Apple's Computer Company Inc Old Logo
In other words these corporations are trying to influence and bring up a postive reaction in us by using these colorful logos propaganda because it has to do with how people were learned to think from the Kinder Garden onwards, especially in democratic countries and probably less in ex-communist totalitarian countries (because they were excluded more or less fromt he global rest of the world for many years), though color programming was partially used also in ex-communist contries too but in a less agressive way than in democratic countries.
With all said above I guess / assume Google (creators) or some of the management and CEO personal undertstood this people's natural daily inflicted love for colorfulness quite well not only because of its psychological materrial meaning but also because Google founders Larry Page and Sergey Brin have been told a mystical teaching about colors that is being preached heavily in recent years by pseudo scientific (occult) companies like Herrmann Brain Dominance Institute HBDI the infamous business module so much loved and adopted by modern businesses – (HBDI) as well as the colors hidden meanings as believed in secret (closed) societies such a masonry fraternities and their front organizations such as Rainbow Girls, Shriners etc..
Logo of Masonic Order Rainbow girls together with Masonic Square and Compass famous symbol
Probably the importance of exposed Google Logo colors is not a coincidence but same colors order is important for both Jewish (because of the Rainbow's importance in the Holy Bible Old testament as a sign of covenant God give between God and man as a promise the world will be no more destroyed by Water Flood), that is still strictly followed by Jewish.
Besides that the Google logo colors are also to be seen as one of central symbols of Free Masonry the Eastern Star (note that it is the same as the Satanists Pentagram), Partially in Gay Lesbian and Homosexual Movement's flag logo and many new founded companies that are adopting and embedding occult meaning it in their company brands exposing them selve who are their masters.
An important Masonic Star (Same is seen in Lavey's Church of Satan but in a circle)
Homosexuals movement logo (flag)
With all said, if you're like me and you want to continue use Google as a Search engine and not switch to Something like Russian's Yandex / Yahoo or DuckDuckGo etc. and want to keep using Google but disable annoying Color propaganda of Google Logo and the Google Doodle's that exposes you to people and events that are often anti-Christian (or never related to Christianity) but showing a pop-culture idolizing personalities many of whom are known for their liberal ideas and non-christian world view (e.g. indoctrinating you slowly but surely with secularism and globalistic) ideas, or if you want me to be "politically incorrect" to save yourself from Google Brainwashing.
Strangely perhaps not a co-incidence this colorfulness and order of color, very much resembles the Buddhist prayer flags used heavily by Buddhists (hanged on their large temples), I guess this is not strange since nowdays the Western culture is crazy of integrating Eastern teachings into their Post-Christian "enlightenment" world.
Removing the Google Search Colorful Logo (Substitute Logo with Blank Space) in Mozilla Firefox Web Browser
I've tried a couple of methodologies to get rid of Annoying Google colorful logo that started to be really irritating for me by using DOOD Remove Firefox plugin which was supposed to be able to allow me change the Google Logo site to whatever I like but the link pointing to the FF DOOD Remove plugin was broken, I then tried using a simple hack with GreaseMonkey and My Google Logo and Background changer on my Firefox Version 38.0.1 but as the script used to be last tested reported working on 18-05-2013 as of time of writting this article it didn't work nomore because of some changes in how google serve its Logo Images. I knew there is a way to also dump the logo using some of the embedded Firefox Javascripts but as I was lazy and don't have a good understanding on JS, I decided to not continue that way and instead tried another method with Adblock Plus's custom Filterint capabilities that is able to filter any picture or object out of a html web page.
Using ABP to remove Google Logo turned to be the easiest and only working solution to remove Google's Logo, to do you need to:
1. Have AdBlockPlus extension for Firefox installed first
2. Enter ABP Options menu by either right-clicking the extension's icon and choose Filter Preferences as shown in prior screenshot.
3. Go to the Add filter Group button (Type Google and then, click Add Filter button and enter google.*/logos/doodles/, as shown in below screenshot
Then give it a try just open www.google.com and you will not see anymore the Google logo, unfrotunately the Logo flashes for less than a second until it is removed but this is the best I can achieve at current point.
Removing the Google Search Colorful Logo (Substitute Logo with Blank Space) in Google Chrome Browser
I've also done a short research on how is possible to Remove Google logo if using Google's Chrome browser and it seems the only meaningful thing I found here is again DOOD Remove (extension) for Chrome.
I've give DOOD Remove for Chrome a try and it works fine, however when you want to open Google you get a short second flash of the Google Logo (after typing google.com in URL bar) before you get the logo wiped so though this works the solution is unfortunately not perfect, the other option to remove the Google Logo branding from searches in Chrome was also to use the Greasemonkey + Userscript as well as Tampermonkey + DoodleGone's script as explained in this post however after enabling TamperMonkey + DoodleGone, the Google logo still was appearing in a behind the search bar (so this worked not), the Google Chrome version where I tried this solution is
Google Chrome 43.0.2357.81 (Official Build) m (32-bit).
So finally it turned out that in order to Disable Google's Kindergarden like looking Logo in Chrome (which is manipulately crafted to inflict kiddish feelings in yourself), I had to Adblock Plus Methodology as described above.
The ABP method to get rid of the ugly google logo also seems to be the only Method that works to remove the Google Logo on Mac OS's (Safari browser).
Hope my article helps others who want to Ban the Google Doodles Logo in your favourite web browser the only condition is to have the Adblock Plus for the browser.
Enjoy Google free logo browsing Google Search engine ! 🙂
Resume sftp / scp cancelled (interrupted) network transfer – Continue (large) partially downloaded files on Linux / Windows
Thursday, April 23rd, 2015 
I've recentely have a task to transfer some huge Application server long time stored data (about 70GB) of data after being archived between an old Linux host server and a new one to where the new Tomcat Application (Linux) server will be installed to fit the increased sites accessibility (server hardware overload).
The two systems are into a a paranoid DMZ network and does not have access between each other via SSH / FTP / FTPs and even no Web Access on port (80 or SSL – 443) between the two hosts, so in order to move the data I had to use a third HOP station Windows (server) which have a huge SAN network attached storage of 150 TB (as a Mapped drive I:/).
On the Windows HOP station which is giving me access via Citrix Receiver to the DMZ-ed network I'm using mobaxterm so I have the basic UNIX commands such as sftp / scp already existing on the Windows system via it.
Thus to transfer the Chronos Tomcat application stored files .tar.gz archived I've sftp-ed into the Linux host and used get command to retrieve it, e.g.:
sftp UserName@Linux-server.net
Password:
Connected to Linux-server.
sftp> get Chronos_Application_23_04_2015.tar.gz
….
The Secured DMZ Network seemed to have a network shaper limiting my get / Secured SCP download to be at 2.5MBytes / sec, thus the overall file transfer seemed to require a lot of time about 08:30 hours to complete. As it was the middle of day about 13:00 and my work day ends at 18:00 (this meant I would be able to keep the file retrieval session for a maximum of 5 hrs) and thus file transfer would cancel when I logout of the HOP station (after 18:00). However I've already left the file transfer to continue for 2hrs and thus about 23% of file were retrieved, thus I wondered whether SCP / SFTP Protocol file downloads could be resumed. I've checked thoroughfully all the options within sftp (interactive SCP client) and the scp command manual itself however none of it doesn't have a way to do a resume option. Then I thought for a while what I can use to continue the interrupted download and I remembered good old rsync (versatile remote and local file copying tool) which I often use to create customer backup stragies has the ability to resume partially downloaded files I wondered whether this partially downloaded file resume could be done only if file transfer was only initiated through rsync itself and luckily rsync is able to continue interrupted file transfers no matter what kind of HTTP / HTTPS / SCP / FTP program was used to start file retrieval. rsync is able to continue cancelled / failed transfer due to network problems or user interaction activity), that turned even pretty easy to continue failed file transfer download from where it was interrupted I had to change to directory where file is located:
cd /path/to/interrupted_file/
and issue command:
rsync -av –partial username@Linux-server.net:/path/to/file .
the –partial option is the one that does the file resume trick, -a option stands for –archive and turns on the archive mode; equals -rlptgoD (no -H,-A,-X) arguments and -v option shows a file transfer percantage status line and an avarage estimated time for transfer to complete, an easier to remember rsync resume is like so:
rsync -avP username@Linux-server.net:/path/to/file .
Password:
receiving incremental file list
chronos_application_23_04_2015.tar.gz
4364009472 8% 2.41MB/s 5:37:34
To continue a failed file upload with rsync (e.g. if you used sftp put command and the upload transfer failed or have been cancalled:
rsync -avP chronos_application_23_04_2015.tar.gz username@Linux-server.net:/path/where_to/upload
Of course for the rsync resume to work remote Linux system had installed rsync (package), if rsync was not available on remote system this would have not work, so before using this method make sure remote Linux / Windows server has rsync installed. There is an rsync port also for Windows so to resume large Giga or Terabyte file archive downloads easily between two Windows hosts use cwRsync.
Windows add / delete services command sc.exe create/delete – Create or Delete services
Thursday, April 9th, 2015 
If you end up in situation where you need to delete or create services from current existing ones with a batch script because it is existing on multiple servers and you want to automate / deploy it via batch (.bat) script you will have to use sc.exe tool – Service Controller Command Tool
SC.EXE command is standard windows console tool to create and delete services. If you want to create a new service, you can use the "create" parameter.
1. Deleting Service with Windows Service Controller Tool
Deleting service is very easy to do you just have to know the service you like to remove not to be listed or Automatically start
sc delete SERVICE_NAME_TO_BE_REMOVED
Below is a real time example on how to remove Apache webserver configured to auto-start
sc.exe delete ApacheService
[SC] DeleteService SUCCESS
2. Create / Add service to existing to auto start on Windows
Before running sc.exe create command with arguments for service you will need to know following info:
- What will be the Service Name: A single word to name the new service.
- Full Binary Path: The path name where the executable program for new service is currently located.
- Dispaly Name for service: A short name for the new service.
C:\Windows>sc.exe create ApacheService
binPath= "C:\local\apache\bin\httpd.exe -k runservice"
DisplayName= "Apache Server"
[SC] CreateService SUCCESS
Once service is added to be showing in services.msc GUI you can start the newly added Apache service with:
C:\Windows>sc.exe start ApacheService
SERVICE_NAME: ApacheService
TYPE : 10 WIN32_OWN_PROCESS
STATE : 2 START_PENDING
(NOT_STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x2
WAIT_HINT : 0x7530
PID : 2552
FLAGS :
To stop the ApacheService or any other service:
C:\Windows>sc.exe stop ApacheService
SERVICE_NAME: ApacheService
TYPE : 10 WIN32_OWN_PROCESS
STATE : 3 STOP_PENDING
(NOT_STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x4
WAIT_HINT : 0x7530
To get the status of a running service lets say the recently ran ApacheService:
C:\Windows>sc.exe query ApacheService
SERVICE_NAME: ApacheService
TYPE : 10 WIN32_OWN_PROCESS
STATE : 4 RUNNING
(STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
As you see from above output the STATE of service is RUNNING. If Apache Webserver was not running you will get an error like:
[SC] EnumQueryServicesStatus:OpenService FAILED 1060:
The specified service does not exist as an installed service.
Enjoy sc-ing 🙂
How to check Java JAR JDBC / ODBC version on Linux / Unix and Windows server
Tuesday, March 31st, 2015 
If you're forced to update some Java based Web application using Java + Tomcat / WebSphere / Weblogic it is a common thing that the Java App developer handed to you will ask you which version is the Oracle JDBC / ODBC driver on current Java Virtual Machine version installed.
Actually there are few methods to check Java JDBC / ODBC version:
1. Check Java ODBC version greeping it in WEB-INF/MANIFEST.MF
Usually the .jar file comes archived in a .ZIP – i.e. application-name5 .zip
server:~# unzip application-name5.zip
Then if the .zip file contains the OJDBC as a .JAR extension – (Java Archive), inflate it with jar tool.
server:~# jar -xvf ojdbc7.jar META-INF/MANIFEST.MF
inflated: META-INF/MANIFEST.MF
server:~# grep Implementation META-INF/MANIFEST.MF
Implementation-Vendor: Oracle Corporation
Implementation-Title: JDBC
Implementation-Version: 12.1.0.1.0
Alternative way to check the info (if you don't have java or jar installed on the Linux / Unix machine) is simply with unzip + grep like so:
server:~# unzip -p ojdbc14.jar META-INF/MANIFEST.MF | grep -C 1 version
Manifest-Version: 1.0
Implementation-Version: "Oracle JDBC Driver version – 10.1.0.5.0"
Specification-Title: "Oracle JDBC driver classes for use with JDK1.4"
Specification-Version: "Oracle JDBC Driver version – 10.1.0.5.0"
Implementation-Title: "ojdbc14.jar"
If you're on a Windows (and you have Windows server grep.exe installed), use instead:
C:\jar> unzip -p ojdbc14.jar META-INF/MANIFEST.MF | grep -C version
2. Getting some info with Java JRE tool
You can check some useful Java version info also just with Java Runtime Environment (java) tool
server:~# java -jar ojdbc5.jar
Oracle 11.1.0.7.0-Production JDBC 3.0 compiled with JDK5
TinyProxy Quick and Easy way to run a Proxy Caching server to protect and speed up web traffic on Linux / BSD and Mac
Tuesday, March 24th, 2015 
If you happen to have SSH account on a Dedicated server or a VPS that runs on some kind of UNIX like OS such as Linux / *BSD or just a friends Mac OS notebook and you don't want your HTTP traffic to be sniffed (spyed) by your local ISP, e.g. you want to get some kind of simple Web browsing anonimity on the Internet, easier alternative to using SSH Dynamic Tunnel to Proxify encrypted traffic is to just run a Proxy Cache server on remote *nix host to which you have access and configure your browser to use the host as proxy. Besides enhanced traffic privacy other advantage of running a Proxy server is of course the fact that using proxy server cache significantly improve page speed opening times, optimize web-sites content delivery saving you a lot of bandwidth and off-loads remote sites because already cached content at the proxy is served directly from the proxy server instead of each time requested from the server. Those admins who remember "the dawn of mass internet use" should remember that a lot of the small and middle sized internet providers were into the habit to use Squid transparent proxy with huge Disk Cache in order to speed-up their customers internet page opening times and thus offer a superior service and save money for themselves since the ISPs were also paying not for a bandwidth to end providers but for used overall Traffic.
Historically I've personally used TinyProxy a lot to "obfuscate" my traffic (hide my originating host IP) and to save-bandwidth cause in late 1990's I paid my internet bills based on used traffic and starting a TinyProxy saved me network traffic and hence cut my Internet bill but even today it is great to optimize web traffic.
Usually for a single or few persons proxy it is not worthy to use "Full Featured" Complex Caching servers such as Squid Cache because installing and configuring one has plenty of dependency packages and a lot of time to spend in configuring (dealing with squid's cryptic squid.conf) it is much better and easier to use a light-weight HTTP/HTTPS proxy service (daemon) such as TinyProxy if using Tor Project (Anonymity Online) Network to protect against network surveillance / traffic analysis Privoxy.
Below is TinyProxy package description from Debian
apt-cache show tinyproxy|grep -i desc -A 5
Description: A lightweight, non-caching, optionally anonymizing http proxy
An anonymizing http proxy which is very light on system resources,
ideal for smaller networks and similar situations where other proxies
(such as Squid) may be overkill and/or a security risk. Tinyproxy can
also be configured to anonymize http requests (allowing for exceptions
on a per-header basis).
To install TinyProxy on Debian Linux:
root@debian:~# apt-get update && apt-get install –yes tinyproxy
To TinyProxy on CentOS 6.5 / 7 Linux:
Install first EPEL (Packages for Enterprise Linux) RPM repository (included by default in CentOS 6 / 7) – also possible to install easily on RHELs (but on RHEL you need to add epel rpm package manually)
[root@centos ~]# yum install -y epel-release
[root@centos ~]# yum -y install tinyproxy
Configuring TinyProxy Linux:
On Debian Linux config is in:
vim /etc/tinyproxy.conf
On CentOS / Fedora / RHEL RPM based ones:
vim /etc/tinyproxy/tinyproxy.conf
You might want to change some of below default values:
# User and Group with which TinyProxy will be running
User nobody
Group nogroup
# Default proxy listen port
Port 8888
# Specifies IP (interface) to be used for outgoing proxy host connections
Bind 192.168.0.1
# To which IP address (interface) tinyproxy will listen for connections. If uncommented it will listen to all available network interfaces
Listen 192.168.0.1
# Seconds after which connection will be terminated
Timeout 600
# Where proxy queries will be logged (very useful to keep a history for yourself on pages you have visted), sometimes useful if you wipe out browser cache
Logfile "/var/log/tinyproxy/tinyproxy.log"
# How many clients (connections) can be made to tinyproxy for one client (personal use) 100 is a good value
MaxClients 100
# This two values are settings on how many (minumum and maximum) tinyproxy instances will listen for connection from remote hosts – this should be familiar to people who configured Apache webserver, note that tinyproxy uses process fork and not threads
MinSpareServers 5
MaxSpareServers 20
# This is how many sites connections the proxy will listen to
# if you open 20 sites in 20 tabs which will refresh make here 20
# you might need to raise this if you have 10 clients
StartServers 10
# hosts to allow connection to proxy server from (Be careful to allow only access from your network otherwise you might end up being an open proxy), allowing some hax0r to do something terrible proxying through you
Allow 127.0.0.1
#The Log Level – "Error" is generally Okay, who may like more information can take Notice – Connect and Info
LogLevel Error
# pidfile location
PidFile "/var/run/tinyproxy/tinyproxy.pid"
# The "Via" header is required by the HTTP RFC, but using the real host name
# is a security concern. If the following directive is enabled, the string
# supplied will be used as the host name in the Via header; otherwise, the
# server's host name will be used.
#
ViaProxyName "tinyproxy
To install TinyProxy on FreeBSD
freebsd# cd /usr/ports/www/tinyproxy
freebsd# make install distclean
If you need to change the default TinyProxy port from port 8888 to something else for security reasons edit:
vim /usr/local/etc/tinyproxy.conf
Find port and change is to lets say 7000 or whatever network port is good for you
To make TinyProxy auto start on BSD boot time:
freebsd# vim /etc/rc.conf
tinyproxy_enable="YES"
To start / stop tinyproxy any time use:
freebsd# /usr/local/etc/rc.d/tinyproxy start
For Firefox users I also recommend using TinyProxy is to install FoxyProxy FF extension
Securing TinyProxy traffic with SSH Tunnel
If you're concerned about transferred data security between your client host (Desktop) machine and remote installed Proxy server that your ISP or some malicious guy could sniff your website login credentials using Man in the Middle attack, its also a good idea to use TinyProxy together with SSH Tunnel, that's pretty easy if you have an SSH client on your machine (if you're on a Mac OS X).
ssh User@server.remote-tinyproxy-server-host.com -L 1234:localhost:8888 -N
To make SSH Tunnel Windows users could use Plink or MobaXterm embedded Tunneling interface
Then setup your Firefox / Chrome / Opera browser to use as a Proxy localhost:1234
Secure your work PC internet traffic using SSH Dynamic Tunnel as Proxy to get around Corporate Spy Proxy and Site Filtering
Friday, March 20th, 2015 
If you work for some huge corporations such as IBM / Sony / Toshiba / Concentrix / HP etc. and you're using a Windows Work Computer (notebook), pre-installed with a custom Company software which is by default configured to use a Proxy Server for all your Browsing activities and at a certain point you start being filtered some of the websites you love to visit so much because of some Corporate policies (limitations) at some filtered sites you will start getting empty pages or some nasty filtering messages.
Even if you don't get a filtering message but you know all your Company Internal Network traffic is proxified for the sake of keeping your personal (privacy) high stop browsing using company's default proxy, because all your access requests (passwords) and queries to the internet are probably logged for later (review) in case if you enter the company's paragraph of "non-compliant employee".
If you fail on time to get around the default set "Corporate Proxy", sooner or later you will start getting filtering messages to some of the regular websites you use daily, as I did today while trying to open my personal blog (to check if there are new user comments):
Your request was denied because of its content categorization: "Hacking;Malicious Sources/Malnets;Religion"
For assistance, contact your network support team.
Screenshot of above message from today here
You see this guys or automated Proxy filter became so prudent that my site was filtered because it contains some Proof of Concept (PoC) security tools and content related to Christian (Faith) Religion. I guess its the time to think seriously is there a censorship in large corporations and how far could censorship go and if such censorship so easily adopted in large companies wouldn't same happen also on a backbone ISP level in short future??
If today my site is being filtered out to be unable to open from a corporation network because it contains "Religious" contain I would not be surprised if tomorrow, I've been prohibited to confess publicly my faith in salvation power of the Cross of our Lord Jesus Christ or even already in a blacklist because I'm trying to be a dedicated Orthodox Christian …
The fact that Religion is already perceived in same light as Hacking and Malicious Source or Malnet bots is also very eloquent and shows how very big part of people nowdays (including the person that added my site to this proxy filtering rules) think of religion and in what bad state our society and understanding of freedom and respect for others went.
Obviously it is time to react to this censorship and stop the evil corporation from spying on your traffic and logging all that matches there "kilometer long" prohibited sites filter lists. There are few ways to do that and the most straight forward is to set-up and use a Own Proxy server such as Privoxy / Polipo or Squid Proxy, however the proxy method requires that your company local network doesn't have too strick (restrictive) firewall rules (e.g. you need some port opened to the Internet such as 8080, 3128, 8118, 1080 standard port for (socks) etc.
As many companies are too restrictive in their outbound firewall rules and you might be in situation like with me where Browsers such as Internet Explorer / Opera / Firefox and Chrome are configured to use by default company proxy host (autocache.proxy-ur-company.hp.com:80) (with a custom Proxy PAC file filtering out a whole ranges of useful domains and IPs) and only allowed firewall access outside of local corporate network in on port 22 (for outside ssh session purposes) only.
Then your best way to get across such restrictive network configuration is to run your own home Linux / BSD / Windows server with opensshd installed and use OpenSSH protocol Dynamic Tunneling (Proxy socks5 like) capabilities to tunnel all your favourite Web Browser Traffic (lets say Firefox's) through your remote-home-host.com:22.
- From Windows PC to Create Dynamic SSH Tunnel to remote home SSH use plink
In short once you have installed plink.exe on your PC run manually from command line (cmd.exe)
plink.exe -ssh UserName@remote-home-host.com -P 22 -pw Secret_Password -D 127.0.0.1:8080 -N
For people who use MobaXTerm it is even easier as there is an integrated SSH tunneling input interface which can be used to create the SSH tunnel.
To have a quick way to Enable SSH Dynamic Tunnel button on your Desktop make a SymLink to Plink with Target below command line:
- If from Linux / *BSD / Mac OS host to create Dynamic SSH Tunnel to your remote home SSH server host run in a Terminal
ssh -D 8080 Username@remote-home-host.com
To start tunneling all your Web traffic via just created Dynamic SSH Tunnel to host remote-home-host.com, just set in browser's proxy options to use as proxy socks5 – localhost:8080
To test whether your traffic is going to the Internet from remote-home-host.com open in just set proxy browser www.myip.ru .
You should see your home SSH server IP as IP which made the request to www.myip.ru.
