Yadda ake gano masu kutse a cikin hanyar sadarwar Wi-Fi

Beyond da matakan tsaro cewa muke aiwatarwa a cikin hanyoyin sadarwarmu ta WiFi, waɗannan sune masu yuwuwar cutarwa ta hanyar haɗin da ba'a so ba kawai ba zai cinye bandwidth din mu, amma kuma isa ga fayilolinmu, don haka yana da kyau a shirya don wannan lamarin tare da rubutun cewa saka idanu hanyar sadarwar mu ta WiFi.

Wani ɗan lokaci da ya gabata mun ga yadda ake amfani da kayan aikin da ake kira yanci don gano buɗe tashoshin jirgi na PC, kwamfutar tafi-da-gidanka, tarho ko ma na'ura mai ba da hanya tsakanin hanyoyin sadarwa kawai ta hanyar tantance adireshin IP ɗinsa.

Wannan kayan aikin yana ba da damar gano IPs na PC, kwamfyutocin tafi-da-gidanka, tarho, wayoyi, duk wani abin da aka haɗa da hanyar sadarwar ku. Wannan na iya zama da matukar amfani, ba shakka, don gano masu kutse a cikin hanyar sadarwar ku ta Wi-Fi.

Yadda ake gano masu kutse

1.- Sanya nmap. A cikin Ubuntu da Kalam, wannan zai zama kamar haka:

sudo dace-samun shigar nmap

Waɗanda suke amfani da wasu abubuwan hargitsi za su sami nmap a cikin wuraren aikin hukuma, don haka girkawarsa mai sauƙi ne. Dangane da Arch Linux, nmap yana cikin wuraren ajiye AUR.

2.- Gudu nmap

nmap -sp 192.168.100.1/24

… Ina 192.168.100.1 Yana da IP na na'ura mai ba da hanya tsakanin hanyoyin sadarwa.

Tare da wannan umarnin, muna neman nmap don nuna mana kawai (-sP) IPs na rundunonin da aka haɗa da hanyar sadarwar, yana da kyau a faɗi cewa .1 a ƙarshen ba shi da mahimmanci tunda lokacin aikawa da mashin cibiyar sadarwa / 24 scan 255-2 = 253 mai yiwuwa runduna.

Sakamakon zai zama wani abu kamar haka:

Fara Nmap 5.51 (http://nmap.org) a 2011-08-23 01:27 ART Rahoton binciken Nmap na 192.168.0.1 Mai watsa shiri ya ƙare (latency 0.0019s). Rahoton binciken Nmap don 192.168.0.102 Mai watsa shiri ya tashi (0.00037s latency). Nmap yi: Adireshin IP 256 (2 runduna sama) an bincika cikin dakika 2.78

A halin da nake ciki, na'ura mai ba da hanya tsakanin hanyoyin sadarwa da kwamfutar tafi-da-gidanka kawai ke aiki.

Idan yayin yin haka zamu ga mai masauki, tare da lambar IP daidai, wanda bamu gane ba, akwai yiwuwar suna amfani da hanyar sadarwarmu ta Wi-Fi ba tare da izininmu ba.

Rubuta don faɗakar da mu lokacin da wani ya haɗu

Franklin Aliaga ya kasance mai kirki don ƙirƙirar rubutun da ke sarrafa atomatik yin amfani da nmap don bincika cibiyar sadarwar ku don masu kutse.

Matakan da za a bi su ne:

1.- Sanya abubuwan da ake buƙata:

sudo apt-samun shigar libnotify-bin nmap

2.- Irƙiri rubutun.

sudo gedit faɗakarwa

sannan, muna liƙa rubutu mai zuwa a cikin sabon fayil ɗin da aka ƙirƙira:
