Bengihlala ngicabanga ukuthi ukuphepha akukaze kulimaze, futhi akwenele (Yingakho ke izinga Ungibiza njengomuntu ophambene ngokweqile nangokuphepha kwengqondo ...), ngakho-ke noma ngisebenzisa i-GNU / Linux, angikunaki ukuphepha kohlelo lwami, amaphasiwedi wami (okwenziwa ngokungahleliwe nge pwgen), njll.
Ngaphezu kwalokho, noma ngabe kuthayipha izinhlelo Unix ngokungangabazeki ziphephe kakhulu, ngokungangabazeki kunconywa ukusebenzisa indlela ye- firewall, ilungiselele kahle, ukuze ivikelwe kahle ngangokunokwenzeka 🙂
Lapha ngizokuchazela ngaphandle kobunzima obuningi, ama-tangles noma imininingwane eyinkimbinkimbi yokuthi ungazazi kanjani izisekelo ze- iptables.
Kepha… Yini isihogo ama-iptables?
iptables Kuyingxenye ye-Linux kernel (imodyuli) esebenza ngokuhlunga iphakethe. Lokhu kusho ngenye indlela, kusho ukuthi iptables yingxenye ye-kernel umsebenzi wayo ukwazi ukuthi yiluphi ulwazi / idatha / iphakethe ofuna ukufaka ikhompyutha yakho, nokuthi yini (futhi yenza izinto eziningi, kepha ake sigxile kulokhu okwamanje hehe).
Lokhu ngizochaza ngenye indlela 🙂
Abaningi kuma-distros abo basebenzisa izibhulamlilo, I-firestarter o Umlilo, kepha lezi firewall empeleni 'zivela ngemuva' (ngemuva) sebenzisa iptables, bese ... kungani ungasebenzisi ngqo iptables?
Futhi yilokho engizokuchaza kafushane lapha 🙂
Kuze kube manje kukhona ukungabaza? 😀
Ukusebenzisana iptables kuyadingeka ukuthi ube nezimvume zokuphatha, ngakho-ke lapha ngizosebenzisa sudo (kepha uma ufaka uthanda izimpande, asikho isidingo).
Ukuze ikhompyutha yethu ivikeleke ngokweqiniso, kufanele sivumele esikufunayo kuphela. Bona ikhompyutha yakho kube sengathi bekuyikhaya lakho, ekhaya lakho wena ngokwakhona awuvumeli noma ngubani angene, kuphela abantu abathile obavumile ngaphambili abangangena, akunjalo? Nge-firewalls kwenzeka okufanayo, ngokuzenzakalela akekho umuntu ongangena kwikhompyutha yethu, kuphela labo abafuna ukungena abangena 🙂
Ukufeza lokhu ngichaza, nazi izinyathelo:
1. Vula i-terminal, kuyo faka okulandelayo bese ucindezela [Faka]:
sudo iptables -P INPUT DROP
Lokhu kuzokwanela ukuze kungabikho muntu, akekho noyedwa ongangena kwikhompyutha yakho ... futhi, lo "muntu" akazibandakanyi 😀
Incazelo yomugqa owedlule: Ngayo sibonisa ama-iptables ukuthi inqubomgomo ezenzakalelayo (-P) yakho konke okufuna ukufaka ikhompyutha yethu (INPUT) ukungakunaki, ukungakunaki (DROP)Akekho umuntu ojwayelekile, empeleni, futhi nawe ngeke ukwazi ukungena kwi-inthanethi noma yini, yingakho kuleso sikhumulo kufanele sibeke okulandelayo bese sicindezela [Faka]:
sudo iptables -A INPUT -i lo -j ACCEPT
sudo iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
... angiqondi shit, Yenzani leyo migqa emibili exakile manje? ...
Okulula 🙂
Ulayini wokuqala okushoyo ukuthi ikhompyutha uqobo (ngendlela, lo = localhost) angenza noma yini ayithandayo. Okuthile okusobala, okungahle kubonakale kungenangqondo ... kepha ngikholwe, kubalulekile njengomoya haha.
Umugqa wesibili ngizochaza ngisebenzisa isibonelo / ukuqhathanisa / isingathekiso engangikusebenzisa ngaphambili, ngiqonde ukuqhathanisa ikhompyutha nendlu 🙂 Isibonelo, ake sithi sihlala nabantu abaningi endlini yethu (umama, ubaba, abafowethu, intombi, njll. ). Uma omunye walaba bantu ephuma endlini, kusobala / kunengqondo ukuthi sizobangenisa lapho sebebuyile, cha?
Yilokho kanye okwenziwa yilowo mugqa wesibili. Konke ukuxhumana esikuqalayo (okuvela kwikhompyutha yethu), lapho ngokusebenzisa lolo xhumano ufuna ukufaka imininingwane ethile, iptables izovumela leyo datha in. Ukubeka isibonelo esisodwa sokuyichaza, uma sisebenzisa isiphequluli sethu sizama ukungena kwi-inthanethi, ngaphandle kwale mithetho emi-2 ngeke sikwazi, yebo yebo ... isiphequluli sizoxhuma ku-inthanethi, kepha uma sizama ukulanda idatha ( .html, .gif, njll) kwikhompyutha yethu ukusikhombisa, ngeke ukwazi iptables Izokuphika ukungena kwamaphakethe (idatha), ngenkathi inale mithetho, njengoba siqala ukuxhumeka kusuka ngaphakathi (kusuka kwikhompyutha yethu) futhi ukuxhumana okufanayo yilokho okuzama ukufaka idatha, kuzovumela ukufinyelela.
Ngalokhu silungile, sesivele simemezele ukuthi akekho umuntu ongafinyelela noma iyiphi insizakalo kukhompyutha yethu, akekho umuntu ngaphandle kwekhompyutha uqobo (127.0.0.1) futhi, ngaphandle kokuxhumana okuqalwe kukhompyutha uqobo.
Manje, ngizochaza imininingwane eyodwa ngokushesha, ngoba ingxenye yesi-2 yalesi sifundo izocacisa futhi ikhave kabanzi ngaleli hehe, angifuni ukuthuthuka kakhulu 😀
Kwenzeka ukuthi ngokwesibonelo, bane-website eshicilelwe kwikhompyutha yabo, futhi bafuna leyo webhusayithi ibonwe yiwo wonke umuntu, njengoba besimemezele ngaphambilini ukuthi konke okuzenzakalelayo AKUVUMELEKILE, ngaphandle kwalapho kuboniswe ngenye indlela, akekho noyedwa ozokwazi ukubona iwebhusayithi. Manje sizokwenza noma ngubani abone iwebhusayithi noma amawebhusayithi esinawo kukhompyutha yethu, ngoba lokhu sikubeka:
sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT
Lokhu kulula kakhulu ukukuchaza 😀
Ngalolo layini simemezela ukuthi wamukela noma uvumela (-J YAMUKELA) wonke umgwaqo oya ethekwini 80 (–Bika 80kwenze kube yi-TCP (-p tcp), nokuthi futhi ithrafikhi engenayo (-OKUFAKELWA). Ngibeka i-port 80, ngoba lelo yitheku lomphathi wewebhu, okungukuthi ... lapho isiphequluli sizama ukuvula isayithi kukhompyutha ye-X, kuhlala kubukeka ngokuzenzakalela kulelo chweba.
Manje ... okufanele ukwenze uma wazi ukuthi imiphi imithetho okufanele uyibeke, kepha lapho siqala kabusha ikhompyutha siyabona ukuthi ushintsho aluzange lulondolozwe? ... kahle, ngalokho sengivele ngenza esinye isifundo namuhla:
Ungaqala kanjani imithetho ye-iptables ngokuzenzakalela
Lapho ngiyichaza kabanzi 😀
Futhi lapha kuyaphela Isifundo sokuqala cishe iptables yama-newbies, anelukuluku futhi anentshisekelo Don't… ungakhathazeki, ngeke kube owokugcina hehe, olandelayo uzobhekana nento efanayo, kepha imithetho ecacisiwe, echaza yonke into kancane futhi yande ezokuphepha. Angifuni ukunweba lokhu okuningi, ngoba empeleni kuyadingeka ukuthi izisekelo (okufunde lapha ekuqaleni) zikuqonde kahle 🙂
Sanibonani futhi ... wozani, ngicacisa ukungabaza, inqobo nje uma niyazi impendulo LOL !! (Angiyena uchwepheshe kulokhu kude hahaha)
Kuhle kakhulu! Umbuzo nje? Ngabe unawo umqondo wokuthi ziyini izilungiselelo ezizenzakalelayo? Umbuzo uphikisana nokuthi ngimane nje: D.
Ngiyabonga kakhulu
Ngokuzenzakalelayo, kahle ngokwakhona kwamukela yonke into. Ngamanye amagama, insizakalo oyifaka kukhompyutha yakho ... isevisi ezoba sesidlangalaleni kwabanye 😀
Uyaqonda?
Ngakho-ke ... lapho ungafuni iwebhusayithi ye-X ukuyibona KANYE nomngane wakho, noma i-IP ethile, kuza i-firewall, i-htaccess, noma enye indlela yokwenqaba ukufinyelela.
Ukulawula,
Mfowethu, Kuhle kakhulu !!!! Manje sengizofunda owokuqala ...
Ngiyabonga ngosizo lwakho…
I-Disla
Siyabonga ngesifundo, siza kahle.
Ukuphela kwento engingathanda ukuyazi noma ukuqiniseka ukuthi uma ngalezi ziqondiso ngeke ngibe nezinkinga ukwenza ukudluliselwa kwe-p2p, ukulanda amafayela noma ukushaya izingcingo zevidiyo, isibonelo. Ngokwalokho engikufunde cha, akufanele kube nezinkinga, kepha ngincamela ukuqiniseka ngaphambi kokungena kolayini.
Ngiyabonga kusukela manje.
Ukubingelela
Akufanele ube nezinkinga, kepha lokhu kungukucushwa okuyisisekelo, esifundweni esilandelayo ngizochaza ngokugcwele ukuthi ungayengeza kanjani imithetho yakho, kuya ngesidingo sayo, njll.
Kepha ngiyaphinda ngithi, akufanele ube nezinkinga, uma unazo nje qala kabusha ikhompyutha futhi kuphelele lapho, njengokungathi awukaze ulungiselele ama-iptables ables
Qala kabusha? Kuzwakala kakhulu windowsero. Esimweni esibi kakhulu, kufanele nje ukhiphe imithetho ye-iptables bese usetha izinqubomgomo ezizenzakalelayo UKWAMUKELA futhi udaba lulungisiwe, ngakho-ke i-rockandroleo, ngeke ube nezinkinga.
Ukubingelela!
Futhi, ngiyaxolisa ukwenza esinye isicelo, kepha njengoba sisesihlokweni se-firewall, kungenzeka ukuthi uchaze ukuthi ungayisebenzisa kanjani le miyalo efanayo kuzindawo zokuqhafaza zomlilo ezinjenge-gufw noma i-firestarter.
I-De antemano, gracias.
Ukubingelela
Ngizochaza i-Firestarter, i-gufw ngiyibonile kuphela futhi angizange ngiyisebenzise kanjalo, mhlawumbe ngizoyichaza kafushane noma mhlawumbe izinga ngizenzele 🙂
Lapho-ke lapho ngifuna ukuzizwa njengesigebhuzi ngizoyifunda, bengihlala ngifuna ukufunda ngezokuphepha
Isifundo esihle kakhulu, ngicabanga ukuthi sichazwe kahle kanti ngenkathi kuyisinyathelo ngesinyathelo kungcono, njengoba besho lapho, kuma-dummies.
Ukubingelela
hahahaha ngiyabonga 😀
Kuhle.
Kuchazwe ngokusobala.
Kuzodingeka ukuthi uyifunde futhi uphinde uyifunde kuze kube yilapho ulwazi selulungisiwe bese uqhubeka ngezifundo ezilandelayo.
Ngiyabonga ngale ndatshana.
Ngiyabonga 😀
Ngizamile ukuyichaza njengoba ngifisa ukuthi ngabe ngichazelwe okokuqala, LOL !!
Sanibonani
Kuhle kakhulu, ngiyahlola futhi kusebenza kahle, okuhambelana nokuqala imithetho ngokuzenzakalela ekuqaleni ngizoyishiya lapho ushicilela ingxenye yesibili, kuze kube yileso sikhathi ngizoba nomsebenzi omncane wokuthayipha imiyalo njalo lapho ngiqala kabusha I-PC, ngiyabonga mngani nge-tuto nangendlela oyishicilele ngayo ngokushesha.
ngiyabonga ngesincomo nezincazelo.
Ungabona ukuthi yini esebenza ngama-iptables nge:
sudo iptables -L
Ngqo 😉
Ngifaka i- n empeleni:
iptables -nLNgiyabonga ngesifundo, ngibheke phambili engxenyeni yesibili, imikhonzo.
ingxenye yesibili izophuma nini
Ngine-proxy ene-squid ku-Machine1, izonikeza ukuphequlula i-inthanethi kweminye imishini kuleyo lan 192.168.137.0/24, futhi ilalele ngo-192.168.137.22: 3128 (ngivula itheku 3128 kunoma ngubani onomlilo) Ngafaka i-firefox ukusebenzisa ummeleli 1: 192.168.137.22 kuyasebenza. Uma kusuka kwenye i-pc ene-ip 3128 ngokwesibonelo, i-Machine192.168.137.10, ngiyibeka ukuze isebenzise ummeleli 2: 192.168.137.22 ayisebenzi, ngaphandle kokuthi uma ku-Machine3128 ngifaka i-firestarter ukwabelana nge-inthanethi ne-lan, lapho uma ummeleli iyasebenza, idatha yokugeleza nge-proxy, kepha uma ku-Machine1 basusa ukusetshenziswa kommeleli futhi bakhombe isango kahle bazokwazi ukuhamba ngokukhululeka.
Kumayelana nani lokhu?
Ngama-iptable imithetho ingaba yini?
"Ngizama ukuhlala ohlangothini olumnyama lombutho, ngoba kulapho kumnandi khona impilo." futhi nge-delirium ye-jedi hahahahaha
Kuhle kakhulu! Ngiphuzile kancane angithi? haha okuthunyelwe kucishe kube yiminyaka emi-2 ubudala kepha bengisizakala kakhulu .. Ngiyabonga ukukuchazela kalula ukuze ngikuqonde haha ngiqhubeka nezinye izingxenye ..
Siyabonga ngokufunda 🙂
Yebo, okuthunyelwe akuyona into entsha ngokuphelele kepha kusasebenza kakhulu, akukashintshi cishe noma yini ngokusebenza kwezingilazi kule minyaka eyishumi edlule engicabanga ukuthi 😀
Ngiyabingelela futhi ngiyabonga ngokuphawula kwakho
Yeka incazelo ngezimbali nakho konke. Ngingumsebenzisi "we-novice" kepha nginesifiso esiningi sokufunda i-Linux, muva nje bengifunda okuthunyelwe mayelana neskripthi se-nmap ukubona ukuthi ngubani oxhumeke kunethiwekhi yami futhi angakwenzi ube mude, emazwaneni kulokho okuthunyelwe umsebenzisi akusho ukuthi Sizosebenzisa umugqa wokuqala odumile owufake kuma-iptables futhi lokho kwakwanele, futhi njengoba ngiyi-noobster enkulu, ngiyisebenzise kepha njengoba ubhalile lapha, ayifakanga kwi-Intanethi 🙁
Ngiyabonga ngalokhu okuthunyelwe okuchaza ukusetshenziswa kwama-iptables, ngethemba lokuthi uzokwelula futhi uchaze ngokuphelele ukusebenza kwawo kimi. Halala!
Ngiyabonga ngokufunda nokuphawula 🙂
iptables iyamangalisa, iyawenza umsebenzi wayo wokucisha, ngakho-ke ... asikwazi nokuzikhipha thina, nakanjani, ngaphandle kokuthi sazi ukuthi singayilungisa kanjani. Kungakho ngizamile ukuchaza ama-iptable ngokulula ngangokunokwenzeka, ngoba kwesinye isikhathi akubona bonke abantu abakwaziyo ukuqonda okuthile okokuqala.
Siyabonga ngamazwana, maqondana ^ _ ^
I-PS: Mayelana nokwelula okuthunyelwe, nansi ingxenye yesi-2: https://blog.desdelinux.net/iptables-para-novatos-curiosos-interesados-2da-parte/
Ngiyabonga kakhulu, uma ngifunde ingxenye yesibili bese ngiqala ukudlala ikhonsoli ngesiqondisi sakho esikhulu. Ngiyabonga kakhulu, awu ngendlela engithemba ukuthi ungangisiza ngayo njengoba nginokungabaza okuncane futhi njengoba wazi kahle ukuthi ngingu-newbie ozama ukufunda ngale software enhle emahhala, kuze kube manje, ngisanda kufaka i-distro ehlukile lapho ngiguqule khona ifayela le-dhcp.config umugqa futhi ngalishiya kanjena:
#send host-name ""; Yebo, kungisebenzele kuleyo distro futhi konke bekuhamba kahle, igama lami le-pc aliveli kuseva ye-dhcp yomzila wami, kuphela isithonjana se-pc, kepha kule distro entsha ngishintshe umugqa ofanayo ngiwushiya unjalo kodwa akuzange kusebenze. Ungakwazi ukungiqondisa kancane? Ngiyacela ...
Njengoba lokhu kungase kube yinto eyinkimbinkimbi noma ebanzi, dala isihloko esithangamini sethu (inkundla.desdelinux.net) futhi lapho sindawonye sizokusiza 🙂
Siyabonga ngokufunda nokuphawula
Silungile, ngiyabonga ngempendulo. Kusasa ekuseni ngizokwenza isihloko futhi ngithemba ukuthi ungangisiza, ukubingelela futhi nakanjani ukunganga.
Indatshana enhle kakhulu.
Ngabe ucabanga ukuthi ngalokhu ngingaqalisa ukusebenzisa i-firewall ngisebenzisa iptables endlini yami noma ngidinga ukwazi okwengeziwe? Ngabe unakho okokufundisa kokumisa noma okusala nalezi zihloko?
imikhonzo
Empeleni lokhu bekulokhu kuyisisekelo naphakathi, uma ufuna okuthile okuthuthuke kakhulu (njengemikhawulo yokuxhuma, njll) ungabheka konke okuthunyelwe okukhuluma ngama-iptables lapha - » https://blog.desdelinux.net/tag/iptables
Kodwa-ke, ngalokhu cishe nginazo zonke i-firewall yangakithi 🙂
Akubonakali kubi nhlobo ekuqaleni.
Kepha kungashintsha okuthile.
Bengizolahla okokufaka bese ngidlulisa bese ngamukela umphumela
-P INPUT -m state-state ESTABLISHED, RELATED -j ACCEPT
Lokho kunganela i-newbi kuma-iptables ukuthi "iphephe kahle"
Ngemuva kwalokho, vula amachweba esiwadingayo.
Ngilithanda kakhulu ikhasi, banezinto ezinhle kakhulu. Siyabonga ngokwabelana!
Ukubingelela!
Sanibonani kusihlwa kubo bonke abaphawulile, kepha ake sibheke ukuthi ungacacisa yini ukuthi kungani ngilahlekile kakhulu kunempisi emgodini wendle, nginguCuba futhi ngicabanga ukuthi siqhubeka njalo kuzo zonke izihloko ezikhona futhi kahle: Uxolo ngaphambi kwesikhathi uma akuhlangene neze nesihloko !!!
Ngineseva ye-UBUNTU Server 15 futhi kuvela ukuthi nginensizakalo ebanjwe ngaphakathi enikezwa olunye uhlelo olusakaza i-TV kepha ngiyazama ukuyilawula ngekheli le-MAC ukuze ichweba lilawule ngokwesibonelo 6500 elikhetha ngokungahleliwe Akekho umuntu ongangena kulelo chweba ngaphandle uma kunekheli le-MAC eliboniswe kuma-iptables. Ngenze ukucushwa kwalesi sihloko kunombolo eyodwa futhi kusebenza kakhuluyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy kahle, kangcono kunalokho ebengikufuna kodwa ngifune imininingwane ku-todoooooooooooo futhi angitholanga ukulungiswa okuhle ukuvumela ikheli le-mac ukuthi lisebenzise ichweba elithile kuphela hhayi okunye.
Ngikubonga kusengaphambili!
Sawubona, unjani, ngifunde i-athikili iptables yama-newbies, muhle kakhulu, ngiyakuhalalisela, angazi okuningi nge-linux, yingakho ngifuna ukukubuza umbuzo, nginenkinga, uma ukwazi ngisize ngiyabonga, ngine-server enama-IP amaningi futhi njalo ezinsukwini ezimbalwa, lapho iseva ithumela ama-imeyili ngama-IP akuseva, iyeka ukuthumela ama-imeyili, ukuze ikwazi ukuthumela ama-imeyili futhi kufanele ngibeke:
/etc/init.d/iptables ayeke
Lapho ngikubeka lokho, iqala ukuthumela ama-imeyili futhi, kepha ngemuva kwezinsuku ezimbalwa iphinde ivinjwe futhi, ungangitshela ukuthi yimiphi imiyalo okufanele ngiyibeke ukuze iseva ingavimbi ip? Bengifunda futhi kulokho okushoyo ekhasini, ngale migqa emi-2 kuzofanele ixazululwe:
ama-sudo iptables -I-INPUT -i lo -j YAMUKELA
ama-sudo iptables -I-INPUT -m state-state ESTABLISHED, RELATED -j ACCEPT
kepha njengoba ngingazi ukuthi yilokho okuyikho, ngaphambi kokufaka leyo miyalo bengifuna ukubheka ukuthi ngabe ama-IPs eseva ngeke esavinjelwa yini, ngilindele impendulo yakho esheshayo. Ozithobayo. UNicholas.
Sawubona, sawubona, ngifunde isifundo sakho esincane futhi kwabonakala kukuhle kakhulu futhi ngenxa yalesi sizathu ngithanda ukukubuza umbuzo:
Ngingaqondisa kanjani kabusha izicelo ezifakwa kusixhumi esibonakalayo (i-localhost) ziye kwenye ikhompyutha (enye i-IP) enembobo efanayo, ngisebenzisa into enjengale
iptables -t nat -A PREROUTING -p tcp –dport 3306 -j DNAT –kuya ku-148.204.38.105: 3306
kepha ayingiqondisi kabusha, ngiqapha itheku 3306 nge-tcpdump futhi uma ithola amaphakethe kepha ingawathumeli ku-IP entsha, kepha uma ngenza izicelo kwenye ikhompyutha iyaziqondisa kabusha. Ngamafuphi, ingiqondisa kabusha lokho okungena nge -i eth0, kepha hhayi lokho okungena nge -i lo.
Ngaphambi kwesikhathi ngithokozela usizo oluningi noma oluncane onganginika lona. salu2.
Sawubona, unjani, leli khasi lihle kakhulu, linemininingwane eminingi.
Nginenkinga futhi bengifuna ukubona ukuthi ungangisiza yini, nginePowerMta efakwe kuCentos 6 neCpanel, inkinga ukuthi ngemuva kwezinsuku ezimbalwa iPowerMta iyeka ukuthumela ama-imeyili ngaphandle, kufana nokuthi ama-IP avinjiwe, futhi usuku ngalunye kufanele ngibeke umyalo /etc/init.d/iptables ume, ngalokho i-PowerMta iqala ukuthumela ama-imeyili futhi phesheya, inkinga ixazululwe izinsuku ezimbalwa, kodwa iphinde yenzeke futhi.
Uyazi ukuthi ngingenza kanjani ukuxazulula le nkinga? Ngabe kukhona engingakulungisa kwiseva noma ku-firewall ukuze lokho kungaphindi kwenzeke? Njengoba angazi ukuthi kungani lokho kwenzeka, uma ungangisiza mina ngiyabonga, ngiyethemba impendulo yakho izosheshe.
