[resolved] sFTP problem

[Anonymous]

Hello,
When i try to connect to my sFTP server i've got the following message :
Exception in component tFTPConnection_1
com.jcraft.jsch.JSchException: Algorithm negotiation fail
    at com.jcraft.jsch.Session.receive_kexinit(Session.java:583)
    at com.jcraft.jsch.Session.connect(Session.java:320)
    at com.jcraft.jsch.Session.connect(Session.java:183)
(same problem in password mode or private key mode)
I use TOS 5.6.2 and "jsch-0.1.51.jar"

Thanks.

It looks like you are trying to use Kerberos authentication correct or the server expect this.

Hi

I had the same issue using TOS 6.1 to connect to a FTP with implicit TLS.

I had the sftp support checked.

Following this thread, I downloaded jsch-0.1.55, copied it into D:\Talend\TOS_DI-20151214_1327-V6.1.1\workspace\.Java\lib and renamed it jsch-0.1.51.jar. After restzrting the studio, same issue.

I then copied it to D:\Talend\TOS_DI-20151214_1327-V6.1.1\configuration\.m2\repository\org\talend\libraries\jsch-0.1.51\6.0.0-SNAPSHOT to replace the existing jsch-0.1.51-6.0.0-SNAPSHOT.jar

It now works after restarting the studio

Hope it helps !
