Cov lus txib los tshuaj xyuas yog tias ib qho chaw nres nkoj qhib ntawm peb lub PC / Server lossis lwm qhov chaw deb

Qee lub sijhawm peb yuav tsum paub yog X chaw nres nkoj qhib ntawm lub computer deb (lossis server), lub sijhawm ntawd peb tsis muaj ob peb txoj kev xaiv lossis khoom siv los siv:

nmap

Thawj qhov kev daws teeb meem uas peb txhua tus xav hais tias yog: nmap , saib tsab xov xwm hu ua: Saib qhib cov chaw nres nkoj nrog NMap thiab ntsuas kom tiv thaiv peb tus kheej 

Nyob rau hauv rooj plaub koj tsis xav ua tag nrho scan, tab sis tsuas yog xav paub yog tias muaj qee qhov chaw nres nkoj qhib ntawm X computer / server, nws yuav zoo li no:

nmap {IP_O_DOMINIO} -p {PUERTO} | grep -i tcp

Piv Txwv:

nmap localhost -p 22 | grep -i tcp

O zoo:

nmap 127.0.0.1 -p 22 | grep -i tcp

Qhov no ua tau li cas yooj yim, nws nug tus IP lossis tus tswv yog qhov chaw nres nkoj qhib lossis tsis yog, tom qab ntawd grep lim thiab tsuas yog qhia cov kab uas lawv xav nyeem, ib qho uas qhia lawv yog tias nws qhib (qhib) lossis kaw (kaw) qhov chaw nres nkoj:

nmap

Zoo ... yog, nmap (Kev tshawb nrhiav Network thiab chaw nres nkoj soj ntsuam cov cuab yeej) ua haujlwm rau peb, tab sis tseem muaj lwm cov qauv sib txawv uas koj yuav tsum tau ntaus tsawg dua 🙂

nc

nc lossis netcat, nws yog qhov kev xaiv muaj ntau qhov yooj yim kom paub tias lub chaw nres nkoj qhib lossis tsis yog:

nc -zv {IP_O_DOMINIO} {PUERTO}

Uas yog:

nc -zv 192.168.122.88 80

Ntawm no yog qhov screenshot ua ib qho kev sim rau qhov chaw nres nkoj uas qhib (80) thiab lwm qhov mus rau lwm qhov chaw nres nkoj uas tsis yog (53):

nc

El -zv qhov nws ua yog yooj yim, cov v tso cai rau peb pom tias lub chaw nres nkoj qhib lossis tsis, thaum z kaw qhov kev sib txuas ceev nrooj thaum qhov chaw nres nkoj tshawb xyuas, yog tias peb tsis tso lub z ces peb yuav tau ua a Ctrl + C los kaw cov nc.

telnet

Qhov no yog qhov txawv uas kuv tau siv rau ib ntus (vim tsis lees paub los ntawm cov tau hais tseg), hauv xov tooj telnet ua haujlwm rau peb ntau ntau dua li tsuas yog paub tias lub chaw nres nkoj qhib lossis tsis.

telnet {IP_O_HOST} {PUERTO}

Ntawm no yog ib qho piv txwv:

telnet 192.168.122.88 80

Cov teeb meem nrog telnet yog kaw qhov kev sib txuas. Hauv lwm lub sijhawm, peb yuav tsis muaj peev xwm kaw qhov kev thov telnet thiab peb yuav raug yuam kom kaw lub davhlau ya nyob twg, lossis lwm yam hauv lwm lub davhlau ya dav hlau ua telnet killall lossis qee yam zoo sib xws. Yog vim li cas kuv zam kev siv telnet tshwj tsis yog kuv xav tau tiag tiag.

Qhov kawg!

Xijpeem, Kuv vam tias qhov no tau nthuav rau koj, yog tias ib tug neeg paub lwm txoj hauv kev paub yog tias ib lub chaw nres nkoj qhib lossis tsis muaj lwm lub computer, tso nws hauv cov lus.

    Thiab ua li cas kuv txuas rau VPS dua SSL?

  5.   vidagnu said

    Qhov kuv ib txwm ua yog khiav nmapfe host-ip kom nws muab tag nrho cov tcp ports, tam sim no kom pom qhov qhib udp ports koj yuav tsum khiav:

    nmap -sU tus tswv-ip

    Kuv kuj tau siv telnet ntau dua li lwm yam ntawm lub qhov rais yog tias kuv tsis muaj nmap ntsia, netcat variant tsis rov hais dua rau kuv ...

    Kuv nyuam qhuav pom tias kuv tsis muaj cov chaw nres nkoj uas kuv xav tau qhib, tam sim no kuv yuav tau tshawb nrhiav yuav ua li cas qhib lawv thiaj li yuav ua qhov kuv xav tau. Ua tsaug rau qhov kev koom tes, nws tau pab kuv ntau.
