Kulezi zinsuku bengizama kancane ngokuxhumana okungenayo, ikakhulukazi ukuphatha i-laptop ne-PC yasekhaya ngisebenzisa iselula yami (nge-SSH), ukuze ngiqiniseke ukuthi ukuxhumana kwe-SSH kulungile bengidinga ukubheka ukuthi ngabe ukuxhumana kuvuleke kahle yini kwi-laptop yami.
Leli icebo elincane engithemba ukuthi lizosebenza ngaphezu kweyodwa 🙂
Ngakho-ke ... lapha ngizokukhombisa ukuthi wazi kanjani ukuxhumana noma amachweba owavulile kukhompyutha yakho, nokunye
Kulokhu sizosebenzisa uhlelo lokusebenza: netstat
Isibonelo, ukukhombisa yonke idatha yokuxhuma esiyivulile nezinye ku-ukuphela esikubekayo:
sudo netstat -punta
Endabeni yami kungikhombisa okulandelayo:
Njengoba ukwazi ukubona, ungabona umthetho olandelwayo, idatha etholakele, imbobo yokulalela ne-IP kanye nechweba ne-IP yokuxhumeka okuvunyelwe, uma kungukuxhumeka osekuvele kusunguliwe noma cha, i-PID, njll. Noma kunjalo, idatha eningi 🙂
Uma ngokwesibonelo ufuna ukwazi kuphela ukuxhumana okuvele kusunguliwe, sizosebenzisa i-grep:
sudo netstat -punta "ESTABLISHED"
Endabeni yami kubuya kuphela:
i-tcp 0 0 10.10.0.51:22 10.10.0.10: 37077 ESTABLISHED 23083 / sshd
Lokhu kusho ukuthi nginesicelo se-SSH (port 22) esivulekile kusuka ku-IP 10.10.0.10 (iselula yami).
Kulungile yithiphu nje encane engithemba ukuthi izoba wusizo kuwe 😉
Phendula ngokucaphuna
Njengenjwayelo, ngikhanyisa usuku lwami ngamathiphu awusizo afika kahle.
I-PS: futhi okuhle kakhulu, cishe njalo amathiphu avela esigungwini sethu esimthandayo .. 😀
HAHAHAHA 😀 😀
Ngiyabonga 🙂 futhi yebo, empeleni ngihlala ngithanda ukubeka elinye icebo elithandekayo ukuze ngisebenze ne-terminal hehe
Njengenjwayelo konke akusizi futhi akusho lutho
Kuyathakazelisa. Ngingathanda ukukhomba kakhulu iTheminali, ukuyisebenzisa, ngoba ngibonile ukuthi ziningi izinto ezingenziwa ukusuka lapho.
Yebo, empeleni ungenza izinto eziningi hehehe, kuyamangalisa 🙂
Lapha sibeke okokufundisa okuningi kokuthi ungasebenza kanjani ne-terminal, bheka futhi uma udinga ukuholwa, ngitshele 😀
Phendula ngokucaphuna
Yebo, lokhu kuyindlela enhle.
Empeleni, kukhona "abahlaziyi bembobo" abaningana. Isincomo sami yi-nmap. Kulabo abanentshisekelo ngishiya isixhumanisi: https://blog.desdelinux.net/como-detectar-los-puertos-abiertos-en-nuestra-computadora-o-router/
Halala! UPaul.
Yebo hehe, ngaphandle kokungabaza i-nmap iyithuluzi elihle, kepha kwesinye isikhathi sidinga nje into elula, njengoba isisho noma ibinzana lithi: "awudingi ukubulala umiyane nge-bazooka" 😀
Wow, yeka ukuthi ibinzana libuyekezwe kanjani!
Yebo, ngoba ngokwazi kwami ukuthi uConfucius wakusho lokho, ngabe kwakukhona ama-bazooka ngaleso sikhathi?
Noma kungenzeka ukuthi kwenzeke ngendaba yempisi kanye nendawo encane yokugibela ebomvu:
Impisi: uyaphi, ingubo encane ebomvu ebomvu?
ILittle Red Riding Hood: emfuleni, ukugeza imbongolo yami.
Impisi: Hawu, ishintshe kanjani lendaba!
😀
Enye ewusizo kakhulu: i-sockstat
Futhi muva nje ngifuna enye indlela elula ngaphezu kwe-ntop ukubona ukusetshenziswa kwesixhumanisi, ngithole igugu langempela (okungenani ngombono wami): iftop.
Ungathola imininingwane ethokozisayo ngento efana ne-lsof -Pni: numpuerto
hahaha yebo yebo, umngane wangikhombisa iftop, kuyasiza uma ngiphatha i-server noma into enjalo kodwa ... kwi-laptop yami, ngiyizamile futhi ayingitsheli lutho engingakwaziyo hahaha
Yebo, ngama-iptables ane-deni ngokuzenzakalela, akusekho okuningi okusele ethubeni (ngisho ukuthi, uma usenalo kanjalo), hehe
uzame ukuvivinya i- "iptraf" yize kufanele ugijime njengezimpande isikhombimsebenzisi esibonakalayo esimnandi kakhulu ... kuyasebenza nokubona isivinini ngesikhathi sangempela esixhunywe kuso
Ngisebenzise umyalo ofanayo ku-Windows eminyakeni eyedlule ukubona ukuthi izinto bezihamba kanjani ngezikhathi ezithile kepha kwesinye isikhathi bengidideka, bese ngikhathala bese ngifaka i-firewall ekhombisa konke lokho ngesikhathi sangempela, Ingabe kukhona uhlelo lokusebenza ku-Linux ukwenza ngokufanayo?
Kubonakala kimi ukuthi kukhona konke ukusatshalaliswa okunikezelwe kulokhu. Ngicabanga ukuthi u-Astaro wayengomunye wabo, angiyisebenzisi kepha umngane wami wayenenguqulo yamahhala efakiwe futhi ngokuqinisekile yanikela ngemininingwane eminingi ngesikhathi sangempela sakho konke okwakwenzeka. Impela bakhona abanye abanjalo. Njengamanje ngisebenzisa i-pfSense kuseva futhi yize imininingwane ayinikezayo inganingilizi kangako, ilusizo kakhulu njenge-firewall futhi ngaphandle kokunethezeka ukuphatha, inamandla (iyimfoloko ye-m0n0wall, esekwe kanye ku-FreeBSD).
Ngiyabonga
Ngincoma lapho kwenziwa imihlahlandlela, ukuzama ukuthi ayinikezwa njengezindlela zokupheka okufanele zilandelwe ngaphandle kokunikeza izincazelo zalokho okwenziwayo. Isibonelo, yini i- "-punta"?
Ukusho ukuthi "grep" kusetshenziselwa ukuhlunga imigqa ngokuya ngentambo yombhalo. Unesistimu ngesiNgisi, abanye bangaba nayo ngeSpanishi. Ngakho-ke ukuhlunga imiphumela kungaba ngcono ukukwenza ngentambo "ezinzile" ukumboza womabili amacala:
I-sudo netstat -tip | grep -i esitebeleni
Inketho «-i» Izosinika njengemiphumela imigqa enaleyo ntambo kungakhathalekile ukuthi isonhlamvukazi abakhulu noma abancane.
Ngiyabonga
ngiyaxolisa, kufanele kube yiyunithi yezinhlamvu "establ" 🙂
I-sudo netstat -tip | grep -i isekela
Yize kulula ukubheka amapharamitha, ukubonwa kwakho kuvumelekile:
-p Khombisa i-PID negama lezinqubo
-u khombisa amaphakheji we-udp
-n amakheli wokubonisa namachweba ngenombolo
-t bonisa amaphakheji we-tcp
-a ukukhombisa amasokhethi ukuthi bayalalela noma cha
Kunemingcele eminingi, kepha lokhu kuyasiza kakhulu futhi kuma-Hispanics akha kulula ukubamba ngekhanda ngekhanda
Ithiphu enhle kakhulu. Bengazi nge-netstat -putall ekhombisa namagama wesizinda, noma kwesinye isikhathi kuthatha isikhashana ukuxazulula.
I-athikili inhle kakhulu futhi ngaphezu kokuthi ilusizo kakhulu, ngincoma kuphela ukuthi ubambe okuku-PNG futhi okunesisindo esingu-246kb futhi ngemuva kokuyisebenzisela iwebhu ngekhwalithi engu-60% kubukeka kufana futhi kunesisindo esingu-3kb kuphela.
