Ungabathola kanjani abangena ngaphakathi kunethiwekhi yakho ye-Wi-Fi

Ngaphandle kwe izinyathelo zokuphepha ukuthi sisebenzisa amanethiwekhi wethu we-WiFi, lezi yizisulu ezingaba namandla okuhlaselwa ukuxhumana okungafuneki okungagcini lapho izosebenzisa umkhawulokudonsa wethu, kodwa futhi finyelela kumafayela ethu, yingakho kungcono ukuthi uzilungiselele lokhu okungenzeka unombhalo wokuthi ukuqapha inethiwekhi yethu ye-WiFi.

Esikhathini esedlule sibone ukuthi singalisebenzisa kanjani ithuluzi elibiziwe nmap ukuthola amachweba avulekile we-PC, i-laptop, ucingo noma i-router ngokuchaza ikheli laso le-IP.

Leli thuluzi elifanayo livumela nokuthola ama-IPs ama-PC, ama-laptops, izingcingo, ama-routers noma yini enye exhunywe kwinethiwekhi yakho. Lokhu kungaba wusizo olukhulu, vele, ukuthola abangena kunethiwekhi yakho ye-Wi-Fi.

Indlela yokuthola abangenayo

1.- Faka i-nmap. Ku-Ubuntu nakokuphuma kokunye, lokhu kungaba kanjena:

sudo apt-get ukufaka nmap

Labo abasebenzisa amanye ama-distros bazothola i-nmap ezinqolobaneni ezisemthethweni, ngakho ukufakwa kwayo kulula kakhulu. Endabeni ye-Arch Linux, i-nmap isezinqolobaneni ze-AUR.

2.- Qalisa i-nmap

i-nmap -sP 192.168.100.1/24

… Kuphi 192.168.100.1 Yi-IP yomzila wami.

Ngalo myalo, sicela i-nmap ukuthi isibonise kuphela (-sP) ama-IPs abasingathi axhunywe kunethiwekhi, kufanele ukuthi sisho ukuthi .1 ekugcineni ayinandaba kusukela lapho kuthunyelwa imaski yenethiwekhi engu-24 scan 255-2 = 253 ababungazi abakhona.

Umphumela uzoba into enjengale:

Ukuqala kweNmap 5.51 (http://nmap.org) ngo-2011-08-23 01:27 Umbiko wokuskena we-ART Nmap we-192.168.0.1 Host is up (0.0019s latency). Umbiko weskena weNmap we-192.168.0.102 Host is up (0.00037s latency). I-Nmap yenziwe: Amakheli we-IP we-256 (2 host up up) askenwe ngemizuzwana engu-2.78

Endabeni yami, kuphela i-router ne-laptop yami esebenzayo.

Uma uma senza lokhu sibona umphathi, onenombolo ye-IP ehambisanayo, esingayazi, kungenzeka ukuthi basebenzisa inethiwekhi yethu ye-Wi-Fi ngaphandle kwemvume yethu.

Iskripthi sokusazisa uma othile exhuma

UFranklin Aliaga ubenomusa ngokwanele ukudala iskripthi esisebenzisa ngokuzenzakalela ukusetshenziswa kwe-nmap ukuskena inethiwekhi yakho yabangenayo.

Izinyathelo okufanele zilandelwe yilezi:

1.- Faka ukuncika okudingekayo:

sudo apt-get ukufaka libnotify-bin nmap

2.- Dala iskripthi.

isudo gedit ixwayisiwe

bese sinamathisela umbhalo olandelayo ngaphakathi kwefayela elisanda kudalwa:

#! / bin / bash #script eyenziwe ngu: franklin aliaga # uma ungenalo uhlobo lwe-nmap sudo apt-get ukufaka i-nmap # ngalo myalo we-nmap isibonisa abaphathi abaxhunyiwe # futhi sibasindise kufayela le- *. iskripthi esithuthukisiwe futhi sibuyekezwe ngu: microstudi (tuxapuntes reader) # Guqula lo mugqa ngendlela oyithandayo uma ufuna ukugcina ama-tempos kwenye indlela.

3.- Siyinika izimvume zokwenza:

I-sudo chmod + x ixwayisiwe

4.- Ekugcineni, sifaka iskripthi ku- i-crontab ukusebenzisa njalo kaningi:

i-crontab-e
