He aha nā protocol ʻelua i hoʻohana ʻia no ka hoʻouna ʻana i nā leka uila?
ʻO IMAP a me POP3 ʻelua mau kaʻina leka uila maʻamau no ka lawe ʻana i nā leka uila. Kākoʻo ʻia nā protocol ʻelua e nā mea kūʻai leka uila hou a me nā kikowaena pūnaewele.
He aha ka protocol e hoʻohana ʻia e Windows e kaʻana like i nā faila a me nā mea paʻi ma kahi pūnaewele?
ʻO ka "pūnaewele hana mua" ʻo ia ka ʻōnaehana hana kahi i hoʻohana pinepine ʻia ai ka protocol sharing file i nīnau ʻia. Ma Microsoft Windows, hāʻawi ʻia kahi mahele pūnaewele e ka ʻāpana pūnaewele Windows "File and Printer Sharing for Microsoft Networks", me ka hoʻohana ʻana i ka protocol SMB (Server Message Block) o Microsoft.
He aha nā huaʻōlelo ʻelua i hoʻohana ʻia e wehewehe i ka User Datagram Protocol UDP?
ʻO ka UDP (User Datagram Protocol) kahi protocol pili ʻole o ka ʻohana protocol internet e hana ana ma ka ʻaoʻao transport a ua kuhikuhi ʻia ma 1980 ma RFC (Noi no nā Manaʻo) 768. Ma ke ʻano he lean a aneane hiki ʻole ke hoʻopaneʻe i ka TCP, hoʻohana ʻia ʻo UDP. no ka lawe wikiwiki ʻana i nā ʻeke ʻikepili ma nā pūnaewele IP.
He aha ka mea i hoʻohana ʻia e ʻike ai i ka ʻāpana pūnaewele o kahi helu IP?
ʻO ka "ʻāpana hoʻokipa" o ka helu IP he 0.0.1.22. Ke hoʻohana nei i kāu notation, ʻo ke kolu octet o ip 192.168.33.22 (mask 255.255.224.0) ʻo ia: 001. 00001 . No ka loaʻa ʻana o ka ʻāpana pūnaewele o kahi helu IP, pono ʻoe e hana i kahi binary AND o ka IP address a me kāna netmask.
Pehea e hana ai nā kikowaena DNS?
ʻO Domain Name Servers (DNS) ka like o ka Pūnaewele me kahi puke kelepona. Mālama lākou i ka papa kuhikuhi o nā inoa kikowaena a unuhi iā lākou i nā helu wahi o ka Internet Protocol (IP). Pono kēia no ka mea, ʻoiai he maʻalahi nā inoa kikowaena no ka poʻe e hoʻomanaʻo, nā kamepiula a i ʻole nā mīkini, e komo i nā pūnaewele e pili ana i nā helu IP.
He aha nā awa e wehe ai no ka kaʻana like ʻana i nā faila Windows?
E wehe ana i nā awa kaʻana like ʻana o Windows 2012
- UDP 138, Kaʻana ʻana i ka faila a me ka mea paʻi (NB-Datagram-In)
- UDP 137, Kaʻana ʻana i ka faila a me ka mea paʻi (NB-Name-In)
- TCP 139, Kaʻana ʻana i ka faila a me ka mea paʻi (NB-Session-In)
- TCP 445, Kaʻana ʻana i ka faila a me ka mea paʻi (SMB-In)
He aha ke awa e hoʻohana ai ʻo Windows no ka kaʻana like ʻana i nā faila?
Kaʻana like ʻana o nā faila Microsoft SMB: User Datagram Protocol (UDP) ports mai 135 a hiki i 139 a me Transmission Control Protocol (TCP) awa mai 135 a hiki i 139. Hoʻokipa pololei ʻia ka SMB me ka ʻole o kahi ʻōnaehana kumu hoʻokomo/puka puka (NetBIOS): awa 445 (TCP). a me UPD).
He aha ka Windows file sharing protocol?
ʻO ka Server Message Block (SMB) Protocol kahi protocol kaʻana like ʻana i nā faila, a e like me ka hoʻokō ʻana ma Microsoft Windows ua ʻike ʻia ʻo Microsoft SMB Protocol. ʻO ka pūʻulu o nā ʻeke memo e wehewehe ana i kahi ʻano o ka protocol i kapa ʻia he dialect. ʻO ka Pūnaehana Pūnaewele Pūnaewele maʻamau (CIFS) Protocol kahi dialect o SMB.
Pehea wau e ʻike ai i nā helu IP ma kaʻu pūnaewele?
Ke ʻimi nei i kāu helu IP me ka hoʻohana ʻole ʻana i ke kauoha kauoha
- Kaomi i ka ikona hoʻomaka a koho i nā Settings.
- Kaomi i ka ikona Pūnaewele & Pūnaewele.
- No ka ʻike ʻana i ka IP address o kahi pilina uea, koho iā Ethernet ma ka ʻaoʻao hema hema a koho i kāu pili pūnaewele, e ʻike ʻia kāu IP IP ma hope o "IPv4 Address".
He aha ka Netid a me Hostid?
Hoʻopili pūnaewele. Kaʻana like. Ma ka papa helu ʻōlelo, ua māhele ʻia kahi helu IP o ka papa A, B a me C i netid a me hostid. Hoʻoholo ka netid i ka helu pūnaewele aʻo ka hostid e hoʻoholo i ka mea hoʻokipa i pili i kēlā pūnaewele.
He aha ka ʻāpana pūnaewele a me ka mea hoʻokipa ma kahi helu IP?
ʻO ka octet i loko o ka subnet mask i loaʻa ka 224 he ʻekolu mau 1 binary i loko: 11100000 . No laila ʻo ka "ʻāpana pūnaewele" o ka helu IP holoʻokoʻa: 192.168.32.0. ʻO ka "ʻāpana hoʻokipa" o ka helu IP he 0.0.1.22. Ke hoʻohana nei i kāu notation, ʻo ke kolu octet o ip 192.168.33.22 (mask 255.255.224.0) ʻo ia: 001.
No ke aha e pono ai ka DNS?
ʻO ka mea nui o DNS. Hoʻohana ʻia ka Domain Name System (DNS) e hoʻololi i nā helu IP i nā kikowaena hiki ke heluhelu ʻia e like me bbc.co.uk. Me ka ʻole o DNS, pono e hoʻomanaʻo nā mea a pau i nā kaula helu helu e hiki ai i nā pūnaewele like ʻole, a i ʻole ka helu IP o Google.
He aha nā 13 kumu kumu?
Ma ka huina, aia he 13 mau kikowaena kumu DNS, ua kapa ʻia kēlā me kēia me nā leka 'A' a i 'M'. Loaʻa iā lākou a pau he helu IPv4 a he helu IPv6 ka hapa nui. ʻO ka mālama ʻana i ke kikowaena kumu ke kuleana o ICANN (Internet Corporation for Assigned Names and Numbers).
Pehea ka hana ʻana o DNS i kēlā me kēia pae?
E nānā hohonu kākou i ke kaʻina hana:
- KaʻAnuʻu Hana 1: Noi ʻike.
- KaʻAnuʻu Hana 2: E nīnau i nā kikowaena DNS recursive.
- KaʻAnuʻu Hana 3: E nīnau i nā kikowaena inoa kumu.
- KaʻAnuʻu Hana 4: E noi i nā kikowaena inoa TLD.
- KaʻAnuʻu Hana 5: E nīnau i nā kikowaena DNS mana.
- KaʻAnuʻu Hana 6: E kiʻi i ka mooolelo.
- KaʻAnuʻu Hana 7: Loaʻa ka pane.
He aha ka TCP 139 e hoʻohana ai?
He aha ka Port 445 a me Port 139 i hoʻohana ʻia no? ʻO NetBIOS ke kū nei no ka Pūnaehana Hoʻokomo Kumu Pūnaewele. He polokalamu polokalamu ia e hiki ai i nā noi, nā PC, a me nā Desktops ma kahi pūnaewele puni honua (LAN) e kamaʻilio me ka lako pūnaewele a me ka hoʻounaʻana i nāʻikepili ma o ka pūnaewele.
ʻO wai ke awa i hoʻohana ʻia no ka waihona like?
Ka papa inoa o nā helu Ports: Hoʻomaopopo i nā Folders Shared a me ka Windows Firewall
| Hoʻohui | Ports |
|---|---|
| TCP | 139, 445 |
| UDP | 137, 138 |
Ua paʻa anei ke awa 445?
ʻO ka nui o nā hoʻouka palekana he pāʻani helu; ʻO ia ke kumu o ka nui o nā hoʻouka ʻana me ka hoʻohana ʻana i kahi port TCP 445 he mea kupanaha. Me nā awa 135, 137 a me 139, port 445 kahi awa kuʻuna Microsoft. ʻO ka Malware e ʻimi nei e hoʻohana i nā ʻōnaehana Windows i hoʻopaʻa ʻole ʻia.
He aha ka ʻokoʻa ma waena o SMB a me NFS?
ʻO NFS kahi protocol maoli i nā ʻōnaehana UNIX, ʻoiai ʻo Samba kahi papahana e hāʻawi iā SMB, kahi protocol maoli i nā ʻōnaehana Windows. Kākoʻo ʻo Linux i nā ʻōnaehana faila. Mai ka manaʻo o kahi mea hoʻohana Windows, ʻo SMB wale nō ke koho i loaʻa. ʻAʻole hana like ʻo SMB.
Hiki iā Windows ke hoʻohui iā NFS?
Hoʻoiho a hoʻokomo iā Microsoft Windows Services no Unix (SFU). Pono wale ʻoe e hoʻokomo i ka NFS Client a me ka Mea Hoʻohana Inoa Mapping. Ke hoʻokomo ʻia a hoʻonohonoho ʻia ʻo SFU, e kau i ka pūpū a palapala ʻia i kahi kaʻa me ka hoʻohana ʻana i ka mea hana Map Network Drive a i ʻole mai ka laina kauoha.
ʻOi aku ka wikiwiki o FTP ma mua o SMB?
ʻO SMB kahi mea hana "ʻoiaʻiʻo" kaʻana like ʻana i nā faila akā hilinaʻi ia ma kahi hoʻokō "virtual network" i hiki ʻole ke kaupalena i kāna hana ma ka pae TCP/IP. Hiki i ka FTP ke wikiwiki loa i ka hoʻoili ʻana i nā palapala nui (ʻoiai ʻoi aku ka maikaʻi me nā faila liʻiliʻi).
Hiki i nā kamepiula ʻelua me nā subnet mask ʻokoʻa ke kamaʻilio?
ʻO ka ʻōlelo maʻamau, ʻaʻohe mea ʻelua e loaʻa i ka leka uila IP like ke ʻole lākou ma hope o kahi hāmeʻa NAT. Pono nā kamepiula i nā mea alalai e kamaʻilio me nā polokalamu ʻaʻole ma kā lākou subnet logical like.
He aha ka IP subnetting?
ʻO ka subnetwork a i ʻole ka subnet kahi māhele kūpono o kahi pūnaewele IP. ʻO ka maʻamau o ka hoʻokaʻawale ʻana i kahi pūnaewele i ʻelua a ʻoi aku paha nā pūnaewele i kapa ʻia ʻo subnetting. Hoʻopili ʻia nā lolouila i kahi subnet me kahi hui bit-nui like ʻole i kā lākou mau IP address.
Pehea ka hana ʻana o ka subnetting?
ʻO ka hoʻohana maʻamau o ka subnetting ʻo ia ka hoʻomalu ʻana i ka hele ʻana o ka pūnaewele. Hana ʻia ka subnetting ma ka hōʻaiʻē ʻana i nā bit host a me ka hoʻohana ʻana iā lākou e like me nā bits network. No ka hoʻomaka ʻana, e nānā kāua i kā mākou ʻoihana ʻoihana ABC (192.168.1.0) a me kāna subnet mask (255.255.255.0) e like me ka mea i hōʻike ʻia ma ka binary.
