I-EPSV isusa inkinga yekheli le-FTP, hhayi ukuxhumana kwesibili
Qonda indawo yokugcina idatha ye-passive lapho ukungena kwe-FTP kusebenza nge-proxy kodwa uhlu noma ukulungiselela ukudlulisa kwehluleka.
I-EPSV isavula uxhumano lwedatha lwe-FTP oluhlukile. Ishintsha imininingwane yendawo yokugcina, hhayi inani lezixhumano.
Impendulo ye-PASV evamile inikeza ikheli nechweba. Lelo kheli lingase lingasebenzi ngaphandle kwenethiwekhi yeseva. I-EPSV inikeza ichweba futhi isebenzisa ikheli leseva elihambisana nokuxhumana kokulawula.
Nge-proxy, gcina ubuwena obunengqondo beseva le-FTP. Ikheli lokulalela lomxhumanisi akulona ngokuzenzakalela iseva ephethe ichweba ledatha elibuyisiwe.
Uxhumano lwedatha ludinga futhi umzila we-proxy ohlosiwe kanye nemvume yokufinyelela ichweba elikhethiwe. Ukwamukela i-CONNECT echwebeni lokulawula le-FTP akukuvumeli ukuxhumana kwedatha ngakunye okulandelayo.
Ngaphambi kokucisha i-EPSV, hlola impendulo ye-passive kanye nekheli leseva nechweba elicelelwe ukudlulisa. Ukungena nge-FTP okuphumelelayo kusungula uxhumano lokulawula; kushiya uxhumano lwedatha ukuze luhlolwe. Nge-Python ftplib, landelela zombili izakhi zesokhethi esikhundleni sokuncika kuphela kwisimo esizenzakalelayo se-PySocks.
