Te Whirihora i tētahi Pūoko hei Kohi Raraunga Rere
- Ka hangaia e te pūoko ngā rekoata rere mai i te waka i runga i ōna atanga Ethernet mā te taunoa. E whakaaro ana tēnei whirihoranga taunoa kua honoa te pūoko ki tētahi tauranga SPAN, ki tētahi tauranga Ethernet whakaata rānei. Mena ka taea e ētahi atu taputapu i runga i tō whatunga te whakaputa rekoata rere, ka taea e koe te whirihora i te pūoko i roto i te web te atanga kaiwhakamahi o te tomokanga hei kohikohi i ngā rekoata rere mai i ēnei pūtake ka tuku atu ki te kapua.
- Mena ka whakaputahia e ngā taputapu whatunga ngā momo rere rerekē, me whirihora te pūoko kia kohia ia momo mā runga i tētahi tauranga UDP rerekē. Mā tēnei ka taea hoki te whakatau raruraru
māmā ake. Mā te taunoa, kei te tuwhera ngā tauranga 2055/UDP, 4739/UDP, me te 9995/UDP i te pareārai pūoko ā-rohe (iptables). Ki te hiahia koe ki te whakamahi i ētahi atu tauranga UDP, me whirihora e koe i roto i
te web tomokanga.
Ka taea e koe te whirihora i te kohinga o ngā momo rere e whai ake nei i roto i te web atanga kaiwhakamahi o te tomokanga:
- NetFlow v5 – Tauranga 2055/UDP (tuwhera taunoa)
- NetFlow v9 – Tauranga 9995/UDP (tuwhera taunoa)
- IPFIX – Tauranga 4739/UDP (tuwhera taunoa)
- sFlow – Tauranga 6343/UDP
Kua whakaratohia e mātou ngā tauranga taunoa, engari ka taea ēnei te whirihora ki ō tauranga e pai ana ki a koe i roto i te web atanga kaiwhakamahi o te tomokanga.
Me whiriwhiri ētahi taputapu whatunga i roto i te web te atanga kaiwhakamahi o te tomokanga i mua i te mahi tika:
- Cisco Meraki – Tauranga 9998/UDP
- Cisco ASA – Tauranga 9997/UDP
- SonicWALL – Tauranga 9999/UDP
Ka hāngai te pūmanawa Meraki putanga 14.50 i te hōputu kaweake rangitaki Meraki ki te hōputu NetFlow. Mena kei te whakahaerehia e tō pūrere Meraki te pūmanawa putanga 14.50, neke atu rānei, whirihorahia tō pūoko ki te Momo Probe o NetFlow v9 me te Pūtake o Paerewa. Mena kei te whakahaerehia e tō pūrere Meraki he pūmanawa putanga tawhito ake i te 14.50, whirihorahia tō pūoko ki te Momo Probe o NetFlow v9 me te Pūtake o Meraki MX (kei raro i te putanga 14.50).
Te Whirihora i ngā Pūoko mō te Kohinga Rere
- Takiuru ki te Secure Cloud Analytics hei kaiwhakahaere.
- Tīpakohia Tautuhinga > Pūoko.
- Pāwhiritia te tahua taka-iho Tautuhinga mō te pūoko i tāpirihia e koe.
- Kōwhiria te whirihora i te NetFlow/IPFIX.
Me whai putanga pūoko hou tēnei kōwhiringa. Ki te kore koe e kite i tēnei kōwhiringa, tīpakohia te Āwhina (?) > Tāuta Pūoko On-Prem hei tango i te putanga o nāianei o te ISO pūoko. - Pāwhiritia Tāpirihia he Pūtirotiro Hou.
- Kōwhiria he momo rere mai i te tahua taka-iho Momo Tirotiro.
- Whakauruhia he nama Tauranga.
Ki te hiahia koe ki te tuku i te Enhanced NetFlow ki tō pūoko, kia mōhio koe kāore te tauranga UDP e whirihorahia ana e koe i te tauranga e whirihorahia ana mō te Flexible NetFlow, te IPFIX rānei i roto i tō whirihoranga pūoko. Hei tauiraampWhirihorahia te tauranga 2055/UDP mō te Enhanced NetFlow, me te tauranga 9995/UDP mō te Flexible NetFlow. Tirohia te Aratohu Whirihoranga mō te Enhanced NetFlow mō ētahi atu kōrero. - Kōwhiria he Kawa mai i te tahua taka-iho.
- Kōwhiria he Pūtake mai i te tahua taka-iho.
- Pāwhiritia Tiaki.
E 30 meneti pea te roa ka puta mai ngā whakahōutanga whirihoranga pūoko i roto i te tomokanga.

Hopukia ngā Mōkihi mai i te Pūoko
I ētahi wā, me manatoko pea e te Tautoko Cisco ngā raraunga rere e whiwhihia ana e te pūoko. Ka tūtohu mātou kia mahia tēnei mā te whakaputa i tētahi hopunga mōkihi o ngā rere. Ka taea hoki e koe te whakatuwhera i te hopunga mōkihi i roto i te Wireshark hei whakahou.view nga raraunga.
- SSH ki roto i te pūoko hei kaiwhakahaere.
- I te tohu, patohia te sudo tcpdump -Dā, pēhi i te Enter hei view he rārangi o ngā atanga. Tuhia te ingoa o te atanga Mana o tō pūoko.
- I te tohu, patohia te sudo tcpdump -i -n -c 100 “tauranga "-w" , whakakapi me tō ingoa atanga Mana, me te tau tauranga e rite ana ki ō raraunga rere kua whirihorahia, me me te ingoa mō te pcap i hangaia file, kātahi ka pēhi i te Enter. Ka whakaputa te pūnaha i tētahi pcap file me te ingoa kua tohua mō te rere o taua atanga, mā runga i te tauranga kua tohua.
- Takiuru atu i tō pūoko.
- Mā te whakamahi i tētahi papatono SFTP, pērā i te PuTTY SFTP (PSFTP), WinSCP rānei, takiuru ki te pūoko.
- I te tohu, patohia te "get" , whakakapi me tō pcap i hangaia file ingoa, ka pēhi i te Enter hei whakawhiti i te file ki tō teihana mahi ā-rohe.
Tātarihia te Hopu Packet i roto i te Wireshark
- Tikiake me te tāuta i te Wireshark, kātahi ka whakatuwhera i te Wireshark.
- Tīpakohia File > Whakatuwheratia, kātahi ka tīpako i tō pcap file.
- Tīpakohia Tātari > Wetewaehere Hei.
- Pāwhiritia te + hei tāpiri i tētahi ture hou.
- Tīpakohia te CFLOW mai i te tahua taka-iho o nāianei, kātahi ka pāwhiri i te ĀE. Ka whakahōu te atanga kaiwhakamahi ki te whakaatu i ngā mōkihi e pā ana ki a NetFlow, IPFIX, sFlow rānei. Ki te kore he hua e puta mai, kāore te pcap i roto i ngā mōkihi e pā ana ki a NetFlow, ā, kua hē te whirihoranga o te kohinga raraunga rere i runga i te pūoko.
