PROBLEM WITH AUTH TLS COMMAND

#1 Post by jricaurte » 2018-09-12 17:51

I'm doing an FTP connection between Filezilla server and a client programmed in c, but when i send the AUTH TLS command, the server responds "234 Using authentication type TLS" and then "421 Login time exceeded.Closing control connection". I tried to fix this by disabling the firewalls, but nothing happens. Please help to solve this.

Sounds like you aren't performing a TLS handshake.

AUTH TLS is just stating your intent to perform the handshake. How to shake hands is explained in https://tools.ietf.org/html/rfc5246
