I-Port Checker ye-TCP Ne-Proxy Kwe-inthanethi

Updated: 2026-11-05

Ngaphambi kokuxazulula izinkinga zokuqinisekisa kwe-proxy (407) noma amaphutha okumisa isiphequluli, qinisekisa ukuthi iphothi ye-TCP yeseva ekude iyafinyeleleka ngempela ku-inthanethi yomphakathi. Faka noma iyiphi i-IP yomphakathi noma igama lomsingathi kanye namaphothi e-TCP angafika kwangu-8 ngenhla ukuze ulinganise ukubambezeleka kwangempela kokuxhumana kwe-TCP handshake yezinyathelo ezintathu (SYN → SYN-ACK).

Izinkomba Zamaphothi e-TCP E-Proxy Neseva Avamile

Ama-daemon e-proxy ahlukene (Squid, 3proxy, Dante, HAProxy, Nginx) kanye nezinsizakalo zeseva alalela kumaphothi e-TCP ajwayelekile noma asezingeni eliphezulu:

Amaphothi e-TCP	Iphrothokholi / Insizakalo Evamile	Ukusetshenziswa Kwe-Proxy Neseva Okujwayelekile
`8080`, `3128`, `8888`	HTTP / HTTPS CONNECT Proxy	Amaphothi ajwayelekile e-Squid, 3proxy, kanye namasango e-HTTP(S) e-VinaProxy
`1080`, `1081`	SOCKS4 / SOCKS5 Proxy	Amaphothi okulalela azenzakalelayo e-Dante nama-relay e-SOCKS5
`80`, `443`	HTTP / TLS Web Server	Amaseva ewebhu, ama-reverse proxy, kanye nabalaleli be-proxy abangavinjwa yi-firewall
`10000–60000`	Dedicated High-Range Ports	Yabelwe izabelo ze-proxy ezizinikele ze-IPv4 emile kanye ne-ISP

Ukuxilonga 'Connection Refused' maqondana ne-'Timeout'

OPEN (nokubambezeleka kwe-ms): Umsingathi okude wamukele iphakethe lethu le-TCP SYN futhi wabuyisela i-SYN-ACK—i-daemon ye-proxy noma insizakalo ilalele ngokugcwele.
CLOSED (refused): I-IP yomsingathi iku-inthanethi, kodwa akukho okulalela kuleyo phothi (noma umthetho we-iptables REJECT uthumele iphakethe le-RST).
CLOSED (timeout): I-firewall (AWS Security Group, UFW, Cloudflare, noma isihlungi se-ISP) ilahle ngokuthula iphakethe le-SYN ngaphambi kokuba lifike kuhlelo lokusebenza.

Isinyathelo ngesinyathelo

1
Faka i-IP yomphakathi eqondiwe noma igama lomsingathi
Namathisela i-IP yeseva yakho ye-proxy noma igama lomsingathi le-VPS enkundleni ethi 'Target Public IP'.
2
Cacisa amaphothi e-TCP angafika kwangu-8
Bhala izinombolo zamaphothi ezihlukaniswe ngokhefana (isb., 80, 443, 1080, 3128, 8080 noma iphothi yakho ethile oyabelwe ye-proxy).
3
Chofoza u-'Check Ports' ukuze usebenzise ukuhlola bukhoma kwe-TCP
Iseva yethu iqala ukuxhumana kwangempela kwe-TCP socket kwiphothi ngayinye ngaphansi kokuvikelwa okuqinile kwe-SSRF.
4
Hlola isimo esithi Kuvuliwe/Kuvaliwe kanye ne-RTT ye-handshake
Uma iphothi IVULIWE kodwa i-proxy yakho isahluleka kusiphequluli, qinisekisa imininingwane yakho ye-username:password ku-Proxy Checker yethu.

Imibuzo evame ukubuzwa

Uyini umehluko phakathi kwale Port Checker kanye ne-Proxy Checker?

I-Port Checker ihlola ukufinyeleleka kwe-Layer 4 TCP (SYN / SYN-ACK) kunoma iyiphi iphothi ngaphandle kokuthumela imininingwane ye-proxy. I-Proxy Checker ihlola ukuqinisekiswa kwe-proxy ye-Layer 7 (HTTP CONNECT noma SOCKS5) futhi iqinisekisa i-IP yokuphuma.

Kungani i-Port Checker ivimba amakheli e-`127.0.0.1` noma e-`192.168.x.x`?

Ukuze kube nokuvikeleka (isivikelo se-SSRF), iseva yethu ishaya kuphela amakheli e-inthanethi e-unicast yomphakathi (isPublicIp) futhi yenqaba i-loopback, i-LAN yangasese ye-RFC1918, kanye namabanga we-link-local.

Kungani iphothi yami IVULIWE lapha, kodwa ingafinyeleleki ku-Wi-Fi yasehhovisi lami?

Amanethiwekhi e-Wi-Fi ezinkampani, awamanyuvesi, noma awamahhotela avame ukuvimba ukuxhumana okuphumayo okuya kumaphothi aphezulu angajwayelekile (njenge-3128 noma 30000+). Zama ukushintsha amanethiwekhi noma usebenzise i-proxy elalela kwiphothi ejwayelekile.
