Which error do you get?

 

[basicuser27]

sorry, this is the error I got..
1.txt, Success=false
java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

Is the server using a self signed certificate?

 

[basicuser27]

Hi,

yes I am using a self signed certificate with a Filezilla Server (in Feature it will be a Proftpd)

with this code I get the following message on the filezilla server

FTP.PassiveMode=True
FTP.UseSSL = True
FTP.UseSSLExplicit = True

ssltrustmanager.InitializeAcceptAll

FTP.SetCustomSSLTrustManager(ssltrustmanager)
FTP.Initialize("FTP",ftpshost,ftpsport, ftpsuser,ftpspass)

Filezilla FTP Log:
4 07:59:07 - (not logged in) (10.168.0.175)> Connected on port 990, sending welcome message...


Filezilla Server:
Flag on Enable FTP over SSL/TLS support (FTPS)
Flag on Allow explicit FTP over TLS

Thanks

Call FTP.Initialize before you do anything else.

Either set UseSSL or UseSSLExplicit. Not both of them.

 

[basicuser27]

with this settings

Dim ssltrustmanager As CustomTrustManager
FTP.Initialize("FTP",ftpshost,ftpsport, ftpsuser,ftpspass)

FTP.PassiveMode=True
FTP.UseSSL = True
FTP.UseSSLExplicit = False
ssltrustmanager.InitializeAcceptAll
FTP.SetCustomSSLTrustManager(ssltrustmanager)


I am getting

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

 

[Erel]

TrustManager is currently only relevant for explicit SSL connections.

 

[basicuser27]

Ok, thanks

with
FTP.UseSSL = False
FTP.UseSSLExplicit = True

i am getting
- (not logged in) (x.x.x.x)> Connected on port 990, sending welcome message...

i have already tried to import the custom signed certificate under the security settings on the phone...

 

[basicuser27]

now i have set the port to 21, not to 990

FTP.Initialize("FTP",ftpshost,ftpsport, ftpsuser,ftpspass)    
       FTP.PassiveMode=True
       FTP.UseSSL = False
       FTP.UseSSLExplicit = True
       ssltrustmanager.InitializeAcceptAll
         FTP.SetCustomSSLTrustManager(ssltrustmanager)

with this is now working with authentication with TLS

 234 Using authentication type TLS
