Ka taea te whakamahi ratou sniffers ki te kino me te painga.

Ko te momo matua o sniffers

Ko nga momo matua o sniffers, e kore ai tika te mea te pūmanawa tāutatia e te i runga i te kāpeka rorohiko, ranei hanga i roto i te puka o te āporoiti ipurangi.

He sniffers whai wāhi tātaitanga anake o te tauwhāiti kāpeka IP-wāhitau i roto i te tikanga ki te uru i te rorohiko kaiwhakamahi me rongoa i roto i tona mōhiohio.

Pehea e mahi i te reira?

He hāngai anake ki whatunga i runga i ngā kawa TCP / IP waka hangarau whatunga haukoti a whakatinana hononga mā kāri whatunga Itarangi. taea hoki te tātarihia whatunga ahokore, tuatahi tonu te mea i roto i te pūnaha taua i reira ko te hononga whaiaho (ki te pouara, te taata horo'a ki te pona papamahi ranei PC).

tuku Raraunga kore he wae wāhi i roto i te kupenga, a mā tona wehenga ki pākete me wāhanga paerewa, e, ka te fariiraa i te taha tangohanga e ngā ki te kōwae kotahi. taea ki te aru i te pareparenga katoa tuku taea o ia wāhanga Program-sniffer ko, me i te wa o te whakawhiti (whakamua) pākete wateatanga ki te whakaaro hono ki te whatunga (pouara, ä, whakakā, rorohiko pūrere pūkoro ranei) whakaputaina wāhanga raraunga e hāngai ana, e ai roto i te taua kupuhipa. Ko te kupu, whawhati te kupuhipa riro te tikanga noa, rawa ki te kore e whakamuna reira.

Otiia ara ka whakamahi i ngā hangarau whakamunatanga kupuhipa matatau, e taea te tuku i te reira tahi ki te kī hāngai. Ki te he reira tuwhera ki te kī tiki i te kuware kupuhipa. Ki te whakamunatia te kī te, Ka taea e te hoariri ngāwari te whakamahi i tetahi pūmanawa-pūwetewaehere, e te mutunga hoki arahi ki te hangai raraunga.

Hea ki te whakamahi i whatunga sniffer?

Ko te tino motuhake mara o te whakamahi sniffers. e kore whakaaro ahau e tetahi sniffer watea i Russian he anake nga tikanga e muru ngana ana ki te hanga i te pokanoa kāore i roto i te waka whatunga i roto i te tikanga ki te tiki i ētahi mōhiohio nui.

Ki te taea te whakamahi sniffers angitu rite e ngā kaiwhakarato e kua hāngai i runga i to ratou tātaritanga o hokohoko raraunga hua ona kaiwhakamahi, te whakarei ake i te haumarutanga o ngā pūnaha rorohiko. Ahakoa tuku taua taputapu me tono antisnifferami, i roto i te meka ko reira rite te sniffers tino mau ki te mahi i roto i te huarahi i te ritenga.

O te akoranga, kaiwhakamahi o taua mahi ki kahore tetahi whakamōhio te kaiwhakarato, a kia nui tikanga i roto i tenei. Ko te pea ki te e taea ki te tango i takitahi tetahi fakafepaki'i kaiwhakamahi Private. A maha Ko te tino nui te kaiwhakarato o te tātari waka no te mea e taea te ārai i te reira whakamātau ki te pokanoa i te mahi o whatunga waho, no te tātari uru ki te tuku pākete, ka taea e koe te aroturuki i te whakaurunga ki a ratou i te iti rawa i runga i te pūtake o te taua apatoko IP-wāhitau, e ngana ana ki te haukoti i te wāhanga tuku. Ko Ko te tauira tino māmā tenei, no te mea he nui atu matatini te hangarau katoa.

Whakatau i te aroaro o te sniffer

I mahue peka he taua mea rite te "sniffer". He aha te mea, he inaianei kite i te mārama iti i runga i te mea e taea whenua tautuhi i te "wiretap" sniffer ake.

Ki te he OK te pūnaha rorohiko, me te rere i te hononga whatunga Ipurangi ranei pai, te tohu tuatahi o te wawaotanga i waho ko ki te whakaiti i te auau pākete, whakaritea ki i kī e te ISP. I roto i ngā pūnaha-e hāngai ana Windows i te paerewa tikanga ki te whakatau i te tere o te kaiwhakamahi toharite e whakauaua noa, no te te whatunga tahua mana karanga mā te pāwhiri i runga i te ata ki te hono. Here whakapūtā koe te maha anake o tono tangata, ka riro pākete.

Waihoki, ka taea te hono mahi i roto i te mōhiohio "kaiwhakahaere mahi" whakaatu e hiahiatia ana i roto i te ki tonu, ki te whakaiti tere ano ki te whāititanga o te rauemi ki te e te uru e kawea i roto i. He pai ki te whakamahi i ngā taputapu motuhake, analyzers, e, i te ara, me te mahi i runga i te parau tumu o te sniffer. Ko te mea anake e hiahia ana koe ki te utu i whakarongo, ko tenei te meka anake e tenei momo o te hōtaka i muri tāutanga taea meinga hapa e puta tika ana ki papā ki pātūahi (he pātūahi hanga-i roto i te Windows pūmanawa me te pūmārō "rino" momo tuatoru-rōpū ranei). Na reira, i te wa o nga whiriwhiringa tātari, he reira e minaminatia ki te mono.

mutunga

Here, mau, me nga mea katoa ki te mahi ki te taua mea rite te "sniffer". He aha te mea i roto i ngā o hacking taputapu tiaki ranei, i roto i te parau tumu, kia waiho reira mārama. tonu te reira ki te tāpiri i te kupu torutoru e pā ana ki ngā aporoiti ipurangi. Ratou tika e te nuinga whakamahia e te mūrere ki te whiwhi i te IP-wāhitau o te patunga me te whai wāhi ki te pārongo muna. Ano, e taua ipurangi-sniffer e tona mahi tika, puta ke ano hoki te IP-wāhitau o te hoariri. I roto i tenei whakaaro, he ahua rite ki te tūmau takawaenga ingoamuna e huna i te IP kaiwhakamahi tūturu enei āporoiti. No te mau tumu kitea, e kore raraunga i runga i enei rauemi ipurangi kei rite pokanoa ki tetahi o rorohiko i te tikanga o enei, he ture me te whiua hōtaka rite, a mana e tu.
