Bheka amachweba avulekile ku-Ubuntu

Noma yiluphi uhlelo luxhumana nomunye nge-Intanethi noma ngenethiwekhi yendawo. Amachweba akhethekile asetshenziselwa lokhu, imvamisa i-TCP ne-UDP. Ungathola ukuthi imaphi amachweba akhona asasetshenziswa njengamanje, okungukuthi, athathwe evulekile, usebenzisa amathuluzi atholakalayo ohlelweni olusebenzayo. Ake sibhekisise le nqubo usebenzisa isibonelo sokusatshalaliswa Ubuntu.

Bheka amachweba avulekile ku-Ubuntu

Ukuze ufeze lo msebenzi, siphakamisa ukusebenzisa ikhonsoli ejwayelekile nezinye izinto ezikuvumela ukuthi ubheke inethiwekhi. Ngisho nabasebenzisi abangenalwazi bazokwazi ukuqonda amaqembu, njengoba sizonikeza incazelo ngayinye. Siphakamisa ukuthi uzijwayeze ngezinsiza ezimbili ezihlukile ngezansi.

Indlela 1: lsof

Isisetshenziswa esibizwa ngokuthi i-lsof siqapha konke ukuxhumana kwesistimu futhi sibonisa imininingwane eningiliziwe mayelana nalowo nalowo wabo esibukweni. Udinga ukwaba kuphela impikiswano efanelekile ukuthola imininingwane oyithandayo.

1. Gijima "Isiginali" ngemenyu noma umyalo I-Ctrl + Alt + T.



2. Faka umyalosudo lsof -ibese uqhafaza Ngena.



3. Faka iphasiwedi yokufinyelela ezimpandeni. Qaphela ukuthi uma uthayipha, kufakwa izinhlamvu, kepha azikhonjiswa kukhonsoli.



4. Ngemuva kwakho konke, uzobona uhlu lwazo zonke izixhumi nazo zonke izinhlaka zokuthakaselwayo.



5. Lapho uhlu lokuxhumana likhulu, ungathinta umphumela ukuze isisetshenziswa sibonise kuphela leyo migqa lapho ichweba oludingayo litholakala khona. Lokhu kwenziwa ngokufaka.sudo lsof -i | grep 20814kuphi 20814 - Inani lechweba elidingekayo.



6. Kuhlala kuphela ukufunda imiphumela esevelile.

Indlela 2: nmap

Isoftware yomthombo ovulekile we-Nmap iyakwazi futhi ukwenza umsebenzi wokuthwebula amanethiwekhi wokuxhuma okusebenzayo, kepha isetshenziswa ngendlela ehluke kakhulu. I-Nmap ibuye ibe nenguqulo enesimo sokuqhafaza, kepha namhlanje ngeke ibe lusizo kithi, ngoba akusiluleki ngokuphelele ukuyisebenzisa. Umsebenzi osuselweni ubukeka kanjena:

1. Hola ikhonsoli bese ufaka umsebenzi ngokungenasudo apt-get ukufaka nmap.



2. Ungakhohlwa ukufaka iphasiwedi ukuhlinzeka ukufinyelela.



3. Qinisekisa ukungeza amafayela amasha ohlelweni.



4. Manje, ukubonisa ulwazi oludingekayo, sebenzisa umyalonmap sendhost.



5. Bheka imininingwane emachwebeni avulekile.

Imiyalo engenhla ilungele ukwamukela amachweba angaphakathi, kepha uma unesifiso emachwebeni angaphandle, kufanele wenze izenzo ezihlukile ngokuhlukile:

1. Thola ikheli le-IP yakho yenethiwekhi ngokusebenzisa insizakalo online ye-Icanhazip. Ukuze wenze lokhu, kukhonsoli, fakawget -O - -q icanhazip.combese uqhafaza Ngena.



2. Khumbula ikheli lakho lenethiwekhi.



3. Ngemuva kwalokho, gijimani scan kuyo ngokungenanmapkanye ne-IP yakho.



4. Uma ungatholi imiphumela, kuzobe sekuvalwa wonke amachweba. Uma zivulekile, zizovela ngaphakathi "Isiginali".

Sihlole izindlela ezimbili, ngoba ngayinye yazo ifuna ulwazi kuma-algorithms ayo. Kumele ukhethe okukhethwa kukho okungcono kakhulu futhi ngokubheka inethiwekhi ukuthola ukuthi imaphi amachweba avulekile njengamanje.
