BASH: How to check if your router has a door open


You want to check if your router has correctly open a door ?

k dude here we go

the fist get your ip from internet
the second command uses NMAP , sudo apt-get install nmap

it checks a range of port UDP and TCP from 20000 to 20001
brainless should not try this at home ūüėÄ but with UDP THERE IS A PROBLEM WITH THIS CODE SO SEE THE NEXT

ip=$(dig +short myip.opendns.com @resolver1.opendns.com); nmap -p U:20000-20001,T:20000-20001 $ip 

USE ROOT USER TO RUN THIS :d

 ip=$(dig +short myip.opendns.com @resolver1.opendns.com); nmap -T5 -A -p 20000 -sU $ip

Kde Pulse microphone settings, change microphone on the fly


I was using some software that uses microphone , and i had some problems , for example on palava.tv which is a service like skype o google talk you can  speak and see your friends for free, without registration.

So i had this problem , the default microphone was the internal one so ….i tried to change it on the icon , like you can see here , and i have even reloaded the page but microphone was always the internal one.

i knew that on gnome desktop you have the ability to change mic on the fly and i was searching a way to do the same on kde desktop , so i tried on system settings multimedia but it was not working at all .

so ?         SOLUTION

just install veromix and plasma script engine python  :

         sudo apt-get install plasma-scriptengine-python plasma-widget-veromix ladspa-sdk  swh-plugins 

add vermix to your panel and you will be able to change microphone on the fly , i will use palava.tv to show this feature .

so go here with chrome or chromium www.palava.tv/123testkdemic   now it will ask to allow or deny just use allow button , if you check VEROMIX now you will see RECORDSTREAM with chrome \chromoium icon just click on the ARROW ON THE RIGHT and click again on MOVE TO  ==> so you can select your preferred mic!
