Menene bambanci tsakanin wannan Na'urar Duba Tasha da Na'urar Duba Proxy?

Na'urar Duba Tasha tana gwada samun damar Layer 4 TCP (SYN / SYN-ACK) a kowace tasha ba tare da aika bayanan shiga na proxy ba. Proxy Checker kuma tana gwada tantancewar proxy ta Layer 7 (HTTP CONNECT ko SOCKS5) sannan tana tabbatar da IP na fita.

Me ya sa Na'urar Duba Tasha ke toshe adiresoshin `127.0.0.1` ko `192.168.x.x`?

Don tsaro (kariyar SSRF), uwar garkermu tana kiran adiresoshin intanet na jama'a kawai (isPublicIp) kuma tana kin kewayon loopback, keɓaɓɓen LAN na RFC1918, da kewayon link-local.

Me ya sa tashata ke OPEN a nan, amma ba a iya samun ta daga Wi-Fi na ofis dina?

Hanyoyin sadarwa na Wi-Fi na kamfanoni, jami'o'i, ko otal-otal sukan toshe hanyoyin fita zuwa tashoshi masu lamba mai yawa da ba daidaitattu ba (kamar 3128 ko 30000+). Gwada canza hanyar sadarwa ko amfani da proxy mai sauraro a daidaitacciyar tasha.
