I- Transmission Control Protocol (TCP) isebenzisa iiseti zonxibelelwano ezibizwa ngokuba ngamachwep ukulawula phakathi kwezicelo ezininzi ezahlukeneyo ezisetyenziswa kwisixhobo esifanayo. Ngokungafani nezibuko ezibonakalayo kwiikhomputha ezifana neechwep ze-USB okanye ii- Ethernet , ii-TCP ii-port ziyi-virtual-program inputable numbers between 0 and 65535.
Uninzi lwee-TCP ziii-channel zenjongo eziqhelekileyo ezinokuthi zinikezelwe kwinkonzo njengoko zifunwa kodwa ngenye indlela zihlale zingenzi lutho. Amanye amachweba angaphantsi-manani, kodwa, anikezelwa kwizicelo ezithile. Nangona iipropathi ezininzi zeTCP zizo zicelo ezingasabikho, ezinye zithandwa kakhulu.

Port TCP 0
I-TCP ayisebenzisi ngokwenene i-port 0 yokunxibelelana kwenethiwekhi, kodwa le port iyaziwa kubaxhasi beprogram. Iiprogram ezisekhompyutheni ze-TCP zisebenzisa i-port 0 ngqungquthela ukucela ichweba elikhoyo likhethwe kwaye linikezelwe yinkqubo yokusebenza. Oku kusindisa umprofeti ekufuneka ukhethe ("i-hardcode") inombolo yefowuni engenakusebenza kakuhle kwimeko. Kaninzi "

I-TCP ii-20 nee-21
Iiseva ze- FTP zisebenzisa i- port ye- TCP 21 ukulawula icala labo lweeseshoni ze-FTP. Iseva iphulaphula imiyalelo yeFTP efika kule port kwaye iphendula ngokufanelekileyo. Kwimodi esebenzayo ye-FTP, umncedisi ukongeza ngokusebenzisa i-port 20 ukuqalisa ukudluliselwa kwedatha kumthengi we-FTP.
03 we-08
Port TCP 22
I-Shell ekhuselekileyo (SSH) isebenzisa iiports 22. Iislayiti ze-SSH ziphulaphule kule port ngenxa yezicelo zokungena ngemvume ezivela kubaxhasi abade. Ngenxa yobume bokusetyenziswa, i-port 22 yalo naluphi na umncedisi woluntu uhlala ehlolwe ngabaculi bee-network kwaye ihlolwe ngokubanzi kwiinkonzo zolonxibelelwano lwenethiwekhi. Abanye abameli bezokhuseleko bancoma ukuba abalawuli bafake i-SSH ukufakwa kwipropati eyahlukileyo ukuze bancede ukuphepha ukuhlaselwa, ngelixa abanye baphikisana nolu luhlobo olusebenzayo olusezantsi.
04 we-08
UDP kumachwep 67 no-68
I-Dynamic Host Configuration Protocol (DHCP) iseva isebenzisa i-UDP port 67 ukuphulaphula izicelo ngelixa abathengi be-DHCP badibanisa kwi-port ye-UDP 68.
05 ka 08
Port TCP 80
Ngokuqinisekileyo ichweba elidumileyo kwi-Intanethi, i-port ye-TCP 80 yinto engagqibekanga ukuba iseva ye-HyperText Transfer Protocol (HTTP) kwiWeb kwi-Intanethi ziphulaphule izicelo ze-Web browser.
06 we-08
IDP 88
Inkonzo yebhola ye-Inthanethi ye-Xbox Live isebenzisa amanani amaninzi eefrethi ahlukeneyo kuquka i-port ye-UDP 88.
07 ka 08
UDP amachwep 161 no-162
Ngokungagqibekanga iProsoft Network Management Protocol (SNMP) isebenzisa i-UDP port 161 ngokuthumela nokufumana izicelo kwinethiwekhi elawulwayo. Isebenzisa i-port ye-UDP 162 njengento engagqibekanga yokufumana izibambiso ze-SNMP kwizixhobo ezilawulwayo.

Izibuko ezingasentla 1023
Izinombolo zee-TCP kunye ne-UDP eziphakathi kwe-1024 ne-49151 zibizwa ngokuba zizibuko ezibhalisiweyo . I-Intanethi Echazwe Amanani Eenombolo igcina uluhlu lweenkonzo ezisebenzisa ezi zibuko ukwenzela ukunciphisa ukusebenzisa okuphikisanayo.
Ngokungafani namachweba anamanani aphantsi, abaphuhlisi beenkonzo ezintsha ze-TCP / UDP bangakhetha inani elithile ukuba babhalise ne-IANA kunokuba babe nenani elibelwe lona. Ukusebenzisa izibuko ezibhalisweyo kugweba izithintelo ezongezelelweyo zokukhusela ezisebenzayo iinkqubo kwiindawo ezibuchwebeni ezinamazantsi aphantsi.
