I-ping evela kugeyithi ye-IPsec isebenzisa ikheli lomthombo elihlukile
I-ping eqalwa kugeyithi ngokwayo izikhethela umthombo wayo, futhi lowo mthombo ushintsha inqubomgomo kanye nomzila wokubuya. Khetha isivivinyo esikhombisa lokho okudingayo.
Thumela i-ping ohlangothini olukude kusuka kugeyithi ye-IPsec, ungatholi mpendulo bese uphetha ngokuthi ithunjana liphukile, kuyilapho wonke umthwalo womsebenzi ngemuva kwegeyithi udlulisa ithrafikhi ngokujwayelekile. Le miphumela emibili ayiphikisani. I-ping eqalwa kugeyithi iyiphakethe elinomthombo wasendaweni, futhi igeyithi ikhetha ikheli lomthombo kusuka kuthebula layo yomzila. Lokho kukhetha kungahluka kumakheli asetshenziswa ithrafikhi yangempela yesayithi, lokho kushintsha ukuthi iyiphi inqubomgomo efanayo nokuthi umuphi umzila wokubuya osebenzayo. Nquma ukuthi isivivinyo kufanele sikhombise ini ngaphambi kokufunda noma yini emphumeleni waso.
Imibuzo emithathu ehlukene i-ping engayiphendula
Umbuzo wokuqala ukuthi ingabe uhlangothi olukude luyafinyeleleka nhlobo kusuka kuleli hosti. Owesibili ukuthi ingabe izikhethi zethunjana noma inqubomgomo esekelwe emizileni zivumela ithrafikhi evela kumthombo othile. Owesithathu ukuthi ingabe ithrafikhi edluliselwe phambili kusuka kumthwalo womsebenzi ngemuva kwegeyithi isebenza kusukela ekupheleni kuya ekupheleni. Umyalo owodwa awukwazi ukuphendula yomithathu, futhi ikheli lomthombo yilona elihlukanisa.
Qala ngokukhetha umbuzo. Uma kungenjalo, i-ping ehlulekile iba ubufakazi bomqondo owawunayo kakade.
Kungani igeyithi ikhetha ikheli obungakulindelanga
Uma u-ping indawo oya kuyo, isitaki sasendaweni sikhetha umthombo kumzila ohambisana nayo. Ethunjwaneni elisekelwe emizileni lokho kungaba ikheli lokuxhumana lesixhumi sethunjana, okumiklamo eminingi yesayithi kuyipheya lika-169.254.x.x elikhethelwe ukweqa kwephuzu-kuya-phuzu. Lawo makheli akhona ukuze isixhumanisi sisebenze; awamenyezelwa njengamanethiwekhi omthombo wezinhlelo zokusebenza ohlangothini olukude.
Ngakho-ke uhlangothi olukude lungathola isicelo se-echo esivela kukheli olungenayo indlela yokubuya kulo, noma kwelinye elingafaniswa nanoma yisiphi isikhethi. Ithunjana lingaba nempilo futhi i-ping yehluleke, futhi yilokho kanye okungekho ngempela okuphambene okukhulunywa ngakho kulesi sihloko.
Khetha umthombo ngamabomu
Kugeyithi ye-Linux elawulwayo, khetha umthombo osunikezwe endaweni: ping -c 4 -I 10.30.0.1 10.40.0.20. Amakheli lapha ayizibonelo, ngakho faka ikheli langempela langaphakathi legeyithi nendawo yokugcina ekude yangempela, futhi qinisekisa ukuthi umthombo owukhethayo ungowalolu hlelo futhi uvunyelwe inqubomgomo yesayithi.
Ungaboleki ikheli lomthwalo womsebenzi ukuze ulisebenzise esivivinyweni. Ukuzenza umuntu ongenayo igeyithi kudala umphumela ongeke ukwazi ukuphindwa muntu, futhi kwezinye izitaki kwehluleka ngezindlela ezibonakala njengokonakala kwethunjana.
Funda umzila wokubuya, hhayi isicelo kuphela
Hlola ukuthi imuphi umthombo ofika ngempela endaweni ekude, kuhlanganise noma yikuphi ukuhumusha ngamabomu endleleni. Bese uhlola umzila wokubuya wohlangothi olukude oya kulowo mthombo kanye nezikhethi noma inqubomgomo eziwuvumelayo. Isicelo esifika nomthombo ongalindelekile siyindaba yomzila nenqubomgomo, hhayi ye-cryptography.
Lapha futhi ukubamba amaphakethe kusiza ngaphezu kwenye i-ping: kukhombisa umthombo owabonwa uhlangothi olukude, futhi yiloyo kheli okufanele lifinyelelwe impendulo yalo.
Bese uvivinya umthwalo womsebenzi
Isivivinyo esinqumayo i-ping esuka kuhosti evamile ngemuva kwegeyithi iya kuhosti evamile ngemuva kwegeyithi ekude. Lokho kuvivinya indima yegeyithi yokudlulisa, umthombo wangempela wohlelo lokusebenza kanye nomzila wokubuyayo wangempela, futhi yilokho ukuhamba okukhathaza abasebenzisi.
Gcina imiphumela ihlukene kumanothi akho: ukufinyeleleka kusuka kugeyithi, ukuvunyelwa kwenqubomgomo komthombo okhethiwe, kanye nethrafikhi edluliselwe phambili. I-ping ehlanganisiwe ngempumelelo iyubufakazi obusizo bokuthi ithunjana lithwala okuthile; akusibufakazi bokuthi konke ukuhamba okudluliselwe phambili kuyasebenza. Futhi umthombo wegeyithi ozikhethele wona ongafinyeleleki awusibufakazi bokuthi ithunjana lesayithi livaliwe.
Ungangezi umzila ojwayelekile we-169.254.0.0/16 ukuze nje uthole impendulo eyodwa yokuxilonga. Lokho kushintshanisa isivivinyo esikhohlisayo nesinqumo somzila esihlala njalo, futhi umuntu olandelayo usithola njengefa ngaphandle komongo.
