PortQRY Native Windows command line Nmap like port scanner – Check status of remote host ports on Windows

Monday, June 30th, 2014

Linux users know pretty well Nmap (network mapper) tool which is precious in making a quick server host security evaluation.
Nmap binary port is available for Windows too, however as nmap is port for its normal operation you have to install WinPcap (Packet Capture Library).
And more importantly it is good to mention if you need to do some remote port scanning from Windows host, there is Microsoft produced native tool called PortQry (Port Query).

PortQRY is a must have tool for the Windows Admin as it can help you troubleshoot multiple network issues.

As of time of writting this post PortQRY is at version 2, PortQRY tool has also a GUI (UI) Version for those lazy to type in command line.

Port Query UI tool (portqueryui.exe) is a tool to query open ports on a machine. This tool makes use of command line version port query tool (portqry.exe). The UI provides the following functionalities:

   1. Following "Enter destination IP or FQDN to query:”, an edit box needs the user to specify the IP address or FDQN name of the destination to query port status.

   2. The end user is able to choose Query type:

        – Predefined services type. It groups ports into service, so that you can query multiple ports for a service by a single click. Service includes "Domains and Trusts", "DNS Queries", "NetBIOS     communication", "IPSEC", "Networking", "SQL Service", "WEB Service", "Exchange Server",          "Netmeeting", and other services.

You can check detail port and protocol info for each service category by opening Help -> Predefined Services…

PORTQRY is part of Windows Server 2003 Support Tools and can be added to any NT based Windows (XP, 2003, Vista, 7, 8)
 You can download portqry command line tool here or my mirrored portqry version command line port scanner here and PortQRY UI here.

PortQRY comes in PortQryV2.exe package which when run extracts 3 files: PortQry.exe program, EULA and readme file. Quickest way to make portqry globally accessible from win command prompt is to copy it to %SystemRoot% (The environment variable holding default location for Windows Installation directory).
It is good idea to add PortQRY to default PATH folder to make it accessible from command line globally.

PorQry has 3 modes of operation:

Command Line Mode, Interactive Mode and Local Mode


Command Line Mode – is when it is invoked with parameters.

Interactive Mode is when it runs in interactive CLI console


and Local Mode is used whether information on local system ports is required.


Here are some examples on basic usage of portqry:

1. Check if remote server is running webserver is listening on (HTTPS protocol) TCP port 80

portqry -n servername -e 80

Querying target system called:

Attempting to resolve name to IP address…

Name resolved to


TCP port 80 (http service): FILTERED

2. Check whether some common Samba sharing and DNS UDP ports are listening

portqry -n servername -p UDP -o 37,53,88,135

Querying target system called:


Attempting to resolve name to IP address…

Name resolved to


UDP port 37 (time service): NOT LISTENING

UDP port 53 (domain service): NOT LISTENING

UDP port 88 (kerberos service): NOT LISTENING

UDP port 135 (epmap service): NOT LISTENING

3. Scan open ports in a port range – Check common services port range (port 1-1024)

portqry -n -r 1:1024 | find ": LISTENING"

4. Logging network scan output to file

Portqry –n localhost –e 135 -l port135.txt

Querying target system called:


Attempting to resolve name to IP address…

Name resolved to


TCP port 135 (epmap service): LISTENING

Using ephemeral source port
Querying Endpoint Mapper Database…
Server's response:

UUID: d95afe70-a6d5-4259-822e-2c84da1ddb0d

UUID: 2f5f6521-cb55-1059-b446-00df0bce31db Unimodem LRPC Endpoint

Total endpoints found: 38

5. Scanning UDP and TCP protocols port

PortQry -n -e 25 -p both


Querying target system called:

Attempting to resolve name to IP address…

Name resolved to


TCP port 53 (domain service): LISTENING

UDP port 53 (domain service): LISTENING or FILTERED

Sending DNS query to UDP port 53…


6. Checking remote server whether LDAP ports are listening

Portqry -p tcp -e 389
Portqry -n -p tcp -e 636
Portqry -n -p both -e 3268
Portqry -n -p tcp -e 3269

7. Making SNMP community name requests

portqry -n host2 -cn !my community name! -e 161 -p udp

8. Initiating scan from pre-selected source port

A network socket request initiation is useful from certain port because, some remote services expect connection from certain ports, lets say you're connecting to mail server, you might want to set as a source port – port 25, to make remote server another SMTP is connecting.

portqry -n -e 25 -sp 25

9. Scanning whether server ports required by Active Directories are opened

Common ports used in Windows hosts to communicate between each other to sustain Active Directory are:

88 (Kerberos)
135 (RPC)
389 (LDAP)
445 (CIFS)
3268 (Global Catalog)

portqry -n -o 88,135,389,445,3268 -p both

portqry has also a silent mode with the "-q" switch if you want to get only whether a port is LISTENING (opened).

On port scan it returns three major return codes (very useful for scripting purposes);

  • returncode 0 – if port / service is listening
  • returncode 1 – if service is not listening
  • returncode 2 – if service is listening or filtered

PortQry is very simple port scanner for win sysadms and is precious tool for basic network debugging (services)  on Windows farms, however it doesn't have the powerful cracker functionality, application / OS versioning etc. like Nmap.


Windows add command to PATH variable – Adding (Putty, VIM) new binaries folder to windows %PATH%

Friday, June 27th, 2014

I want to use vim (text editor) on my Windows 7 work computer and hence installed VIM (VI Improved) port for Windows GVim.
VIM works perfect on Windows and for those coming from UNIX background having it installed is a must, however vim doesn't include a PATH location to its (vim) executable in Windows %PATH%.
PATH command line variable stores path locations to all binaries that could be executed directly from cmd line with no need to type full directory path to binary.

To illustrate what PATH is lets say you want to make Putty accessible straight from Windows command line (cmd.exe), you can add Putty's installation Path Folder to global Windows %PATH%. On my 64-bit Windows PC Putty binary is installed in C:Program Files (x86)PuTTY.

echo %PATH%

C:Perl64sitebin;C:Perl64bin;C:Program FilesRA2HP;C:Windowssystem32;C:
Program FilesWIDCOMMBluetooth Software;C:Program FilesWIDCOMMBluetooth Sof
twaresyswow64;C:Program Files (x86)Hewlett-PackardHP ProtectTools Security M
anagerBin;C:Program FilesActivIdentityActivClient;C:Program Files (x86)A
ctivIdentityActivClient;C:Program Files (x86)QuickTimeQTSystem

To make Putty accessible only by typing Putty instead of typing C:Program Files (x86)PuTTYPutty.exe, it has to be included in PATH, normally from Win command line (cmd.exe). This is done with:


set PATH=%PATH%;C:Program Files (x86)PuTTY


echo %PATH%


C:Usersggeorgi7Desktop>echo %PATH%
C:Perl64sitebin;C:Perl64bin;C:Program FilesRA2HP;C:Windowssystem32;C:
Program FilesWIDCOMMBluetooth Software;C:Program FilesWIDCOMMBluetooth Sof
twaresyswow64;C:Program Files (x86)Hewlett-PackardHP ProtectTools Security M
anagerBin;C:Program FilesActivIdentityActivClient;C:Program Files (x86)A
ctivIdentityActivClient;C:Program Files (x86)QuickTimeQTSystem;C:Program
Files (x86)PuTTY

To check all the exported variables, use SET command, here is my default SET variables:


CLASSPATH=.;C:Program Files (x86)
CommonProgramFiles=C:Program FilesCommon Files
CommonProgramFiles(x86)=C:Program Files (x86)Common Files
CommonProgramW6432=C:Program FilesCommon Files

To make inclusion of VIM, Putty or other binary directory) into PATH variable permanent:

From Windows desktop, right-click My Computer and click Properties.
In the Advanced system settings click on Properties window, click on the Advanced tab.
In the Advanced System section, click the Environment Variables button.

Finally, in the Environment Variables window, search for the Path variable in Systems Variable section and click the Edit button.
Add or modify the path lines including the paths to binaries you wish to be easy access.
Note that each different directory should be separated with a semicolon (;), e.g.

C:Program Files;C:Winnt;C:WinntSystem32; C:Perl64bin



How to configure equivalent of Linux /etc/resolv.conf search in MS Windows – DNS Suffix

Thursday, June 26th, 2014


Linux's default file that defines what DNS servers will be used /etc/resolv.conf typically contains directives with the default search domain or domains; used for FQDN (Fully Qualified Domain Name) completion when no domain suffix is supplied as part of the  DNS query. Lets say sub-domains under  has to be accessed (in /etc/resolv.conf) there is:


That is very handy whether you have to ssh or open in web browser (sites) or multiple servers each residing under a single main domain name (for example:,, etc.) by typing in browser or SSH by only passing the sub-domain name i.e.:



ssh user@server1
ssh user@server2

Here is /etc/resolv.conf from

# cat /etc/resolv.conf



Here is example of what I mean, ascii-games is a sub-domain of ( and is resolved with no need to type full FQDN


# host ascii-games has address

The DNS server knows that all failed to resolve queries by set DNS should be searched (resolved) under the defined search domain, i.e. each DNS query for server2, serverX (would try to be resolved as a subdomain of

Therefore, a very good question is what is Microsoft Windows (2000, 2003, 8) OS equivalent way to define search into /etc/resolv.conf?

In Windows the same /etc/resolv.conf hosts search is done using the so called "DNS Suffixes".

DNS Suffixes are used for resolv of (domain name strings with no dots).

Adding a new DNS Suffix in Windows is done from



Control Panel -> Network and Sharing Center -> Change Adapter Settings


Here select LAN card Adapter used to bring Internet to Win host,be it Local Area Connection or

Wireless Network Connection

 and choose:






Network Connection Properties

dialog select

Internet Protocol Version 4 (TCP/IPv4)

and again click on




On next dialog click on


Advanced (button) -> DNS (tab)


In field

DNS Suffix for this connection

fill in host which you would like to resolve with no need for FQDN and press the


(exactly like adding search in  /etc/resolv.conf on Linux host). Add multiple hosts DNS Suffix, if you want to access subdomains naming from multiple base domain.

Check your Joomla Security with OWASP Joomla Vulnerability Scanner

Wednesday, June 25th, 2014


If you working in field of Computer Security you should have definitely heard of OWASP (Open Web Application Security Project).
OWASP is very much like MetaSploit – Penetration Testing Framework except it is focusing mostly on web security.
As of time of wrtitting this post OWASP Project is probably the largest contributor in Web Security tools. If you're somehow in the field of Web and Middleware (Security team) or writting Web Application software (with security in mind) OWASP is definitely a project you should study well and the provided tools can help you develop your web services server infrastructure or application design with top security in mind.

One of the famous OWASP tools is Joomla Security Scanner – a toll that can scan and find all potential and present vulnerability in a Joomla (Pure Joomla or Joomla Based  website). OWASP Joomla Security Scanner script is written in Perl, making it possible to run on any OS Platform that can run Perl and CPAN modules. Thus Joomla Security Scanner is running on Windows, Linux and Mac OS X.

  • To use OWASP Joomla Security scanner on Linux (depending on Linux distribution install perl via deb or rpm package manager – most Linux distributions have it already pre-installed).
  • For Joomla Security scanner on Windows you will have to install one of Perl Windows ports either Active Perl or Strawberry Perl.

Once perl interpreter is up installed, e.g. test it with:

# perl --version

This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi
(with 61 registered patches, see perl -V for more detail)

Download Latest Joolma Vulnerability Scanner (here), in case if tool disappears in future a mirrored version for download of Joomla Vulnerability Scanner is (here)
UnZIP the scanner in new created directory start it run Windows command line (I use ConEmu) – Press Windows button + R (and type ConEmu) – or if you don't have conemu cmd.exe, go to whenever the archive was dearchived:

cd UsersgeorgiDownloadsJoomla-scanner

Install all required CPAN perl modules for Joomla Scanner


This will launch perl cpan installation console, you will see a prompt:


The console is a front end which uses Perl's Cpan modules site to download libraries, CPAN is doing quite a good job as it also downloads dependencies if installed perl module has such.

Inside CPAN console type:

install local::lib

Answer any further prompts by simply pressing Enter a lot of times.
Next install App::cpanminus:

install App::cpanminus

Then Exit CPAN, type:


This should have installed cpanminus to test it run in Linux shell / win command prompt:



Usage: cpanm [options] Module [...]
Try `cpanm --help` or `man cpanm` for more options.


As a last step install Switch from cpanminus:

cpanm -f install Switch

Run Joomla Scanner






Anmap network port scanner – Nmap security scanner for your Android Mobile and Tablet

Tuesday, June 24th, 2014


Those who have to deal with network security or do periodic UNIX / Windows server security audits know  well Nmap (Network Mapper).
NMAP is the swiss army knife tool of choice of both crackers and security exports and it is a must have exploration tool.
For those who just heard of Nmap or want  to learn more on Nmap basics, I recommend my previos articles how to check Windows / Linux host port security (by examples)  and test a local network for open Windows shares.

Nmap is one of the most improtant tools for every cracker (white, grey black hat "hacker"). Nmap is a legendary hack tool and probably the prevelent networt security port scanner tool over the last 10 years on all major Operating Systems. Nmap's high portability is thanks to being open source, being ported so far for:

Window – Zen, Mac OS and Linux, FreeBSD, OpenBSD, NetBSD and even obscure proprietary operating systems like Hewlett Packard's UNIX – HP-UX, Sun Microsystems's UNIX variant Solaris. It is in an interesting fact to mention probably not much known Sun Solaris's core code base is based on Berkley's BSD 4.4 whose fork nowadays give birth to FreeBSD and rest of *BSD family OSes. 
Nmap evolved a lot through the last 7 years from only having a command line interface for hardcode console geeks like me to having a nice shiny GUI frontendinterface ZenMap.
Nmap is popular for being one of the hack tools in the famous move The Matrix (II) – Reloaded.

As hacking and security penetration is quickly moving from PC Desktops and Notebooks to more mobile and stealth variants with recent boom of smartphones – it is no strange that Nmap got ported to the most wide-spread (and very Linux compatible) – Android OS under the name ANmap (Android Map).


ANMap source code and apk – (Android Package file) is on GoogleCode here.

By the way using your android device to scan your own Android device on localhost (just like on above screenshot), could be quite helpful and often could reveal some unwated services, run by malware or viruses application.

To get full use of ANmap's full functionality (Stealth Scan, Full version and port scan etc.)  just like on other operating systems ANmap has to run with super user privileges .

To be able to run applications with Super user access on Android you need to have ROOTED ANDROID  (Tablet / Phone) device – rooting android is just a simply hack that makes Android OS to run certain applciations with root (administrator privileges). Usually Rooting a device breaks ups vendor (reseller) guarantees, so if you root your device to run ANmap on it be very careful to which application you give access to run as super user!
As Anmap page reads: There are some little bugs, as domain names resolving and unroot scanning.

If you want to use Anmap only command line interface (without gui).
Download compiled nmap with data files in this tar ball or this zip archive and keep it in one folder.

Than connect to localhost via ConnectBot, untar and start scanning:

$ tar -xvf nmap-5.51-1.tar
$ su
# ./nmap

Happy scanning 🙂

Run 2 and more Skypes simultaneously on Mac OS X – Run multiple Skype acccounts on same Mac

Saturday, June 21st, 2014

For people running Mac OS X, the question of 
how is it possible to use 2 skype accounts in parallel on Mac probably makes good sense?

I don't own a Mac notebook and thefore I'm a Mac newbie, however, I'm into situation where I and my wife Svetlana went (for 3 days) to my hometown Dobrich and we have with us only her Mac OS X powered Mac Book air.


One user is already logged in Skype, (my wife) is expecting some relatives and friends to contact us and  same time I had to login to check few servers via ssh and discuss some server downtime issues from yesterday in Skype .
Thus we
need 2 skype instances to run separately on her Macbook air powered PC with Mac OS X Leopard

Earlier I've blogged how to make 2 and more Skype accounts work simultaneously on one Windows PC because I had to set it up for a company, in this short article I will explain how is possible to run many skype clients on Mac OS X.


1. Open Mac Terminal from Finder


2. In Terminal run the first Skype Instance

Type in Terminal:

open /Applications/

3. Run Second Skype instance

In older Skype Mac OS versions, I read the


Skype command option was there and could be used to run a second parallel skype instance on Mac, however in newer releases this option was removed and if you try to invoke it warning window pops up saying an instance is already running.


To get around the issue and run the second Skype, quickest way is to run another Skype client under privileged user through sudo command (this is unsecure – but anyways as Mac OS is proprietary and we don't have access to code and probably there are tons of spy and report software integrated into the OS, it doesn't really matter.)


To get around the issue and run the second Skype, quickest way is to run another Skype client under privileged user through sudo command (this is unsecure – but anyways as Mac OS is proprietary and we don't have access to code and probably there are tons of spy and report software integrated into the OS, it doesn't really matter.)

4. Script it into for later use

To run and use two parallel skypes regularly it might be useful to make shell script out of it and place it somewhere, script should be something like:

open /Applications/
sudo /Applications/

Then make the script executable with:

chmod a+x

5. Run more than 2 Skypes (Run multiple Skypes on same Mac PC hack)

There is another "hack" method with deleting the (Process ID). Skype recognize where it is running by checking its on start up.

Deleting the pid after each next Skype client launch,  allow the user to run as many Skypes as you want on Mac OS X but it is not clear for how long it time it will work.

rm -f ~/Library/Application Support/Skype/

Then launch again Skype in background from Mac Terminal

open -nW '/Application/' &

In case if you wonder why the open command is used, since above line could be run also directly and Skype will pop-up, by using open command you instruct the program to detach itself from Terminal from which it run, so later if Terminal is closed Skype app. will not terminate.

Another approach is to create, a many users lets say 5 users and use the Skype sudo run method each client with a separate user.

sudo user1 /Applications/
sudo user2 /Applications/
sudo user3 /Applications/
sudo user4 /Applications/

sudo user5 /Applications/

I enclose the script with the custom icon (Skype) ready to be launched and Voila, on script launch Skype multiple login prompts pops up.

For the lazy ones who don't want to tamper with writting scripts or doing hacks to run Skype multiple times on Mac there is even a Multi Skype Launcher app for Mac.



Allowing MySQL users access from all hosts – Fixing mysql ERROR 1045 (28000): Access denied for user ‘root’@’’ (using password: YES)

Friday, June 20th, 2014


I recently migrated MySQL database server from host A to host B (, because I wanted to have the mysql database server on a separate machine (have separation of server running services and have a dedicated mysql server).

MySQL server host (running on localhost previously was set from my mysql config my.cnf to listen and serve connections on localhost with

bind-address =

). MySQL is used by a Tomcat running Java application on localhost and my task was to set the Tomcat to use the MySQL database remotely to MySQL host B (new remote hostname where MySQL is moved is and is running on IP

Migration from MySQL Db server 1 (host A) to MySQL Db server 2 (host B) is done by binary copying the mysql database directory which in this case is (as it is a Debian server installed MySQL), the standard directory where mysql stores its database data is /var/lib/mysql ( datadir = /var/lib/mysql in /etc/mysql/my.cnf)

Binary copying of data from MySQL db (host A) to MySQL Db (host B) is done with rsync

After migrating and trying to login on migrated mysql  database on with mysql cli client:

remotesysadmin:~$ mysql -u root -p

I got following error:

ERROR 1045 (28000): Access denied for user 'root'@'' (using password: YES)

To fix the issue I had to login remotely from old migration server mysql (host A) cli:

mysql:~$ mysql -u root -p -h

and  run SQL commands:

GRANT USAGE ON *.* TO 'root'@'' IDENTIFIED BY 'secret-mysql-pass';

Query OK, 0 rows affected (0.03 sec)
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)

Another way to solve the problem is to add the root user to be able to connect from any host (Enable MySQL root access from all host), to do so issue:


Note: In newer version of MySQL, flush privileges could be omitted.

Another approach if you want to substitute access from localhost for all users and enable all users to be able to authenticate to mysql remotely is to execute SQL Query:

UPDATE USER SET host='%' WHERE host='localhost';

Allowing all users to be able to connect from anywhere on the internet is a very bad security practice anyways, if you already have a tight firewall setup and you can only access the server via specific remote IP addresses allowing MySQL access from all hosts / ips should be ok.

Screenshot expanded menus on GNOME / KDE in Linux and BSD desktop

Thursday, June 19th, 2014


If you're using actively Linux or FreeBSD on Desktop PC and experimenting with software, taking personal notes, developing software for Linux, writting documentation, participating in free software community etc., you will certainly need use screenshot heavily.

Taking a screenshot in Linux is done in same way as in any modern operating system by using the Print Screen (PrtScr) button, however there are few Nuts & Bolts of Linux screenshotting, to take advantage of full power of screenshot creation (i.e. be able to do some screenshot customization) which are not offered by default screenshot utilities (GNOMEgnome-screenshot and KDE's KSnapshot)

Here are few useful Linux /BSD Screenshot Tips and Tricks:

If you have done screenshots of Linux running programs more than few times already, you have probably noticed the usual way to screenshot by pressing Print Screen (PrtScr) button to take snapshot of the expanded GNOME / KDE menu is not working. In that order of thought you probably wondered whether it is possible to take a screenshot of an expanded menus? As a Linux user, I've been asking myself this question too, and feeling irritated that  I cannot prepare screenshot of a GNOME running application expanded menu. I've found two ways (though there are probably many more to make screenshot of an expanded Linux menu). Here is how:

Create screenshot of running application expanded menus

1. Taking screenshot of expanded menu using the command line

As with everything in Linux, there aremultiple ways to make screenshot of expanded Linux menus.

  • Make timed screenshot of the screen scheduled to screenshot after a set number of seconds.

The quickest way for to screenshot expanded menu is to use gnome-panel-screenshot or ksnapshot from command line. It is interesting pressing Prt Sc kbd button in GNOME invokes gnome-screenshot and in KDE uses ksnapshot


gnome-panel-screenshot --delay 5


To not spend time running it from gnome-terminal (in GNOME desktop), press Alt+F2 (simultaneously) and use the Run Application command shortcut.


This will instruct Screenshot utility to wait for 5 seconds before capturing your desktop this should be enough time for you to go to navigate to expanded menu which you want to get screenshotted.


  • Make timed screenshot of the screen in GUI with GIMP


(If you're wonderhing what kind of Linux is on screenshot – this is Trisquel – Run Free! GNU / Linux. It is a Spanish distribution focused on providing 100% free software in it – without proprietary firmware or software. Trisquel is based on Debian and uses the dpkg / apt-get package managers. Trisquel is a recommended Linux to use by Richard Stallman and The Free Software Foundation).
To make timed screenshot with GIMP use menus:


File -> Create -> Screenshot



Chosee whether you want to Take screenshot of the entire screen or a Region to Grab and set your wanted Delay

Screenshot will be prepared on $HOME/Desktop, after set time.

Linux: basic system CPU, Disk and Network resource monitoring via phpsysinfo lightweight script

Wednesday, June 18th, 2014


There are plenty of GNU / Linux softwares to monitor server performance (hard disk space, network and CPU load) and general hardware health both text based for SSH console) and from web.

Just to name a few for console precious tools, such are:

And for web based Linux / Windows server monitoring my favourite tools are:

phpsysinfo is yet another web based Linux monitoring software for small companies or home router use it is perfect for people who don't want to spend time learning how to configure complicated and robust multiple server monitoring software like Nagios or Icanga.

phpsysinfo is quick and dirty way to monitor system uptime, network, disk and memory usage, get information on CPU model, attached IDEs, SCSI devices and PCIs from the web and is perfect for Linux servers already running Apache and PHP.

1. Installing PHPSysInfo on Debian, Ubuntu and deb derivative Linux-es

PHPSysInfo is very convenient and could be prefered instead of above tools for the reason it is available by default in Debian and Ubuntu package repositories and installable via apt-get and it doesn't require any further configuration, to roll it you install you place a config and you forget it.

 # apt-cache show phpsysinfo |grep -i desc -A 2

Description: PHP based host information
 phpSysInfo is a PHP script that displays information about the
 host being accessed.


Installation is a piece of cake:

# apt-get install --yes phpsysinfo

Add phpsysinfo directives to /etc/apache2/conf.d/phpsysinfo.conf to make it accessible via default set Apache vhost domain under /phpsysinfo

Paste in root console:

cat > /etc/apache2/conf.d/phpsysinfo.conf <<-EOF
Alias /phpsysinfo /usr/share/phpsysinfo
<Location /phpsysinfo>
 Options None
 Order deny,allow
 Deny from all
 #Allow from localhost
 #Allow from
 Allow from all


Above config will allow access to /phpsysinfo from any IP on the Internet, this could be a security hole, thus it is always better to either protect it with access .htaccess password login or allow it only from certain IPs, from which you will access it with something like:

Allow from

Then restart Apache server:

# /etc/init.d/apache2 restart


To access phpsysinfo monitoring gathered statistics, access it in a browser


2. Installing PHPSysinfo on CentOS, Fedora and RHEL Linux

Download and untar

# cd /var/www/html
# wget
# tar -zxvf phpsysinfo-3.1.13.tar.gz
# ln -sf phpsysinfo-3.1.13 phpsysinfo
# mv phpsysinfo.ini


Install php php-xml and php-mbstring RPM packages

yum -y install php php-xml php-mbstring

Start Apache web service

[root@ephraim html]# /etc/init.d/httpd restart

[root@ephraim html]# ps ax |grep -i http
 8816 ?        Ss     0:00 /usr/sbin/httpd
 8819 ?        S      0:00 /usr/sbin/httpd


As PhpSysInfo is written in PHP it is also possible to install phpsysinfo on Windows.

phpsysinfo is not the only available simple monitoring server performance remotely tool, if you're looking for a little bit extended information and a better visualization interface alternative to phpsysinfo take a look at linux-dash.

In context of web monitoring other 2 web PHP script tools useful in remote server monitoring are:

OpenStatus – A simple and effective resource and status monitoring script for multiple servers.
LookingGlass – User-friendly PHP Looking Glass (Web interface to use Host (Nslookup), Ping, Mtr – Matt Traceroute)

SEO: Best day and time to write new articles and tweet to get more blog reads – Social Network Timing

Tuesday, June 17th, 2014


I'm trying to regularly blog – as this gives me a roadmap what I'm into and how I spent my time. When have free time,  I blog almost daily except on weekends (as in weekends I'm trying to stay away from computers). So if you want to attract more readers to your blog the interesting question arises

What time is best to hit publish on your posts?

Now there are different angles from where you can extract conclusions on best timing to blog post.One major thing to consider always when posting is that highest percentage of users read blogs in the morning with their morning coffee. Here are some more facts on when web content is more red:

  • 70% of users say they read blogs in the morning
  • More men read blogs at night than woman
  • Mondays are the highest traffic days for avarage blogs
  • 11 a.m. is normally the highest traffic hour for blogs
  • Usually most comments are put on Saturdays
  • Blogs with more than one post a day has higher chance of inbound links and usually get more unique visitors

As my blog is more technical oriented most of my visitors are men and therefore posting my blogs at night doesn't interfere much with my readers.
However, I've noticed that for me personally posting in time interval from 13:00 to 17:00 influence positively the amount of unique visitors the blog gets.

According to research done by Social Fresh – Thursday is the best day to publish an article if you want to get more Social SharesBest-Day-to-Blog-to-get-more-shares-in-social-networks

As a rule of thumb Thursday wins 10% more shares than all other days. In fact, 31% of the top 100 social share days in 2011 fell on Thursday.
My logical explanation on this phenomenon is that people tend to be more and more bored from their work and try to entertain more and more as the week progresses.

To get more attention on what I'm writting I use a bit of social networking but I prefer using only a micro blogging social networking.  I use Twitter to share what I'm into. When I write a new article on my blog I tweet its title with a link to my article, because this drives people attention to what I have to say.

In overall I am skeptical about social siting like Facebook and MySpace because it has negative impact on how people use their time and especially negative on youngsters Other reason why I don't like Friends Networks is because sharing what you have to say on sites like FB, Google+ or "The Russian Facebook" –  Vkontekte are not respecting privacy of your data.


You write free fresh content for their website for free and you get nothing!


Moreover by daily posting latest buzz you read / watched on Facebook etc. or simply saying what's happening with you, where you're situated now etc., you slowly get addicted to posting – yes for good or bad people tend to be maniacal).

By placing all of your pesronal or impersonal stuff online, you're making these sites better index their sites into Google / Yahoo / Yandex search engines and therefore making them profitable and high ranked websites on the internet and giving out your personal time for Facebook profit? + you loose control over your data (your data is not physically on your side but situated on some remote server, somewhere on the internet).
