Uyini umehluko phakathi kwe-IP, Port ne-Protocol?
Ukuze amadivayisi axhumane kunethiwekhi eyodwa, kungaba inethiwekhi yangaphakathi (i-LAN) noma ku-inthanethi (i-WAN), sidinga izinto ezintathu ezibaluleke kakhulu:
Ikheli lasesizindeni se-inthanethi ( 192.168.1.1 ) ( 10.0.0.2 )
Imbobo ( 80 - 25 - 110 - 21 - 53 - 23 )
Iphrothokholi (HTTP - SMTP -pop - ftp - DNS - telnet noma i-HTTPS
Okokuqala
Ikheli le-IP:
Yisihlonzi sedijithali sanoma iyiphi idivayisi (ikhompyutha, iselula, iphrinta) exhunywe kunethiwekhi yolwazi esebenza kuphakheji yephrothokholi ye-inthanethi, kungakhathaliseki ukuthi inethiwekhi yangaphakathi noma i-inthanethi.
Okwesibili
Iphrothokholi:
Iwuhlelo olutholakala ngokuzenzakalelayo kunoma iyiphi isistimu yokusebenza (Windows - Mac - Linux) Noma iyiphi isistimu yokusebenza emhlabeni inephrothokholi ye-HTTP enesibopho sokuphequlula i-inthanethi.
Okwesithathu
Imbobo:
Ukuba sengozini kwesofthiwe kumasistimu okusebenza, kanye nenani lalobu bungozi busukela phakathi kuka-0 - 65536 wobungozi besofthiwe, futhi ukuba sengozini ngakunye kusebenza kuphrothokholi ehlukile kwenye.
Ukuba sengozini kwesoftware: ukuvulwa noma isango kuwo wonke amasistimu wokusebenza ukuze kulawuleke ukungena nokuphuma kwedatha.
Izinhlobo zamaphrothokholi nezimbobo
Manje sesijwayelene nenani lezivumelwano ezidume kakhulu ze-inthanethi:
I-SMTP noma Iphrothokholi Elula Yokudlulisa Imeyili:
Kuyiphrothokholi yokuthumela i-imeyili nge-inthanethi esebenza ku-Port 25.
Iphrothokholi ye-POP noma Yeposi:
Kuyiphrothokholi yokwamukela i-imeyili nge-inthanethi futhi isebenza ku-Port 110.
I-FTP noma Ifayela Lephrothokholi Yokudlulisa:
Kuyiphrothokholi yokulanda ku-inthanethi futhi isebenza ku-Port 21.
I-DNS noma Isistimu Yegama Lesizinda:
Kuyiphrothokholi ehumusha amagama wesizinda ukusuka emagameni ukuya ezinombolweni okwaziwa njengekheli le-IP elisebenza ku-Port 53.
Inethiwekhi ye-Telnet noma yetheminali:
Kuyiphrothokholi evumela abasebenzisi ukuthi baqhube izinhlelo bekude futhi basebenze ku-Port 23.
