Hi ,
I am trying to connect from a stand alone SFTP client using jsch 0.1.36 to
an SFTP server and getting exceptions:
The key pair were created by some one else and it uses a passphrase. We
are able to login to the server via command prompt using the same key
pair.
I have gone through the archive and spotted similar question but no
solution. Can you please help on why this can happen?
Sample program;
ChannelSftp sftpChannel = null;
UserInfo userInfo = null;
int TRY_ESTABLISH_CONNECTION = 10;
String hosts_FileName = null;
try
{
jsch = new JSch();
jsch.setKnownHosts("C:\\.ssh\\known_hosts");
com.jcraft.jsch.Logger l = new myLogger();
JSch.setLogger(l);
session = jsch.getSession("***", "***", 22);
userInfo = new MyUserInfo();
session.setUserInfo(userInfo);
jsch.addIdentity("***", "***");
session.connect();
sftpChannel = (ChannelSftp)session.openChannel("sftp");
sftpChannel.connect();
sftpChannel.disconnect();
}
catch (Exception e) {
e.printStackTrace();
}
